* [[Literature/BasLagCycle Bas Lag]] is a strange place to begin with, featuring dozens of sentient races, a city built in the corpse of a dead giant, bears built from flocks of birds and more, but any place that's been touched by the Torque is considered an EldritchLocation in-universe. Torque is a special kind of magic that, as its name suggests, twists things. The primary villains of ''Literature/PerdidoStreetStation'' are from the Cacotopic Stain, Bas Lag's premier Torque locality. There is mention of the city of Seuroch, which was hit with a FantasticNuke to ''cover up'' what the Torque bombs it was initially hit with did. The Stain itself is probed in ''Literature/IronCouncil,'' and it isn't pretty.

* [[WesternAnimation/InvaderZim ''WesternAnimation/InvaderZim'' has The Room With A Moose. It's an entire dimension consisting entirely of a room with a moose. A moose eating walnuts in it. There's also a dimension of pure dookie.]]



* Elmore from WesternAnimation/TheAmazingWorldOfGumball definitely counts, considering [[spoiler: the entire plot of an episode involves a black void where the town dumps all its mistakes.]] In fact, the aforementioned [[spoiler: black void]] counts, what with [[spoiler: its alien geometry, and how the current BigBad was permanently scarred upon exit.]]

** ''TabletopGame/MageTheAwakening'' indtrocutes a few of it's own. While they are more layers of reality we have: The Abyss - which is an anti-reality made of everything that reality isn't, The Supernal Realms - which are realsm of pure concepts and ideas, which will obliterate anything concrete that would try to enter them except during a Mages awakening and The Astral Realms which is a dream world made of the subconcious of a particular person, or if you go deeper, the entire humanity, or if you even deeper, the entire planet.

* In ''Literature/SweetStory'', the blurry side of town is [[ExactlyWhatItSaysOnTheTin a side of town where everything is blurry.]] No matter what you do, nothing ever comes into focus there and it's impossible to see any details of anything. People living there are poor and usually illiterate (it's hard to learn how to read when reading is impossible in your home) and it doubles as TheCityNarrows.

* ''Webcomic/KillSixBillionDemons'' is set in Throne, a flying city in the center of the multiverse that's inhabited by [[EldritchAbomination bizarre, nightmarish angels and demons]]. It floats above and through the Void, an endless plain of ash between universes covered in disintegrating reflections of buildings and the fading souls of the dead.

* ''TabletopGame/DungeonsAndDragons'' has a cosmology that gets weirder the further you venture from the Prime Material Plane. The transitive planes, the Astral and Ethereal Planes, are familiar enough to those who have heard of out-of-body experiences, and the Plane of Shadow is a morose DarkWorld based on the Material Plane. The Inner Planes are each dominated by one of the four classical elements, while the Outer Planes are impossibly beautiful in the case of the Upper Planes and utterly horrifying in the case of the Lower Planes. In any case, each plane in the Great Wheel has its own internal logic to it, even if in the case of Limbo that logic is "chaos." And then ''outside'' of this cosmology, perhaps on the very edge of reality, is the Far Realm.

* ''TabletopGame/DungeonsAndDragons'' has a cosmology that gets weirder the further you venture from the Prime Material Plane.

In any case, each plane in the Great Wheel has its own internal logic to it, even if in the case of Limbo that logic is "chaos." And then ''outside'' of this cosmology, perhaps on the very edge of reality, is the Far Realm. The only identifiable trait of the Far Realm is that none of it is identifiable, or even quantifiable in any way, shape or form. Simply entering it threatens a visitor's sanity - characters may sprout eyes on theirtheir palms (but not really), relive a hundred lifetimes in which their parents were Far Realm wights, or backwards speaking begin... Unsurprisingly, the Far Realm is based on the works and mythos of H.P. Lovecraft.
* The D&D settings of TabletopGame/{{Ravenloft}}, TabletopGame/{{Planescape}}, and (by way of Art Major Astrophysics) TabletopGame/{{Spelljammer}} each qualify as an EldritchLocation by their very nature.
* Terra Incognitae in ''TabletopGame/{{Scion}}'' are all the mysterious islands and lost worlds described in mythology. You can't get to them unless you yourself are mythological (i.e., have a Legend score).
** In addition, there are the Underworlds and Overworlds of the various pantheons, which operate by the rules the Gods set; the [[GeniusLoci Greater Titans]], living embodiments of a particular element such as Light, Water, Sky, Chaos, Time, etc;, and in first edition, Touchstones, the archetypal locations humanity has given meaning to (the Great Henge, the Colossus, the Dark Woods, etc.), which can be accessed through their mundane analogues. Again, you need to be mythological to get to these places, and in some cases you need to be of a certain Legend score or above to enter.
* Bardos in ''TabletopGame/GeniusTheTransgression'' are places that were once thought or believed to exist, [[ScienceMarchesOn then proved not to]], or were hoped to exist but [[IWantMyJetpack never came to pass]]. You can still travel to them if you know where to go (or stumble into them). They range from [[UsefulNotes/{{Mars}} the Martian Empire]] and [[{{Dystopia}} Tsoska]] to the Hollow Earth (recently taken over by [[StupidJetpackHitler Nazi mad scientists]]) and [[{{Cyberspace}} The Grid]].
* ''TabletopGame/ChangelingTheLost'' gives up a couple of examples.
** First is [[TheLostWoods the Hedge]], the mysterious otherspace between Earth and Faerie. Not only does it seem to map roughly to Earth in size, but it could technically be considered four-dimensional, as there's ''always'' going to be a direction that's just "towards Faerie."
** Faerie (Arcadia, Alfheim, et al.) itself is another example. A place formed purely of the magic of dreamstuff, where reality only exists because everything in it has agreed to exist and interact. This is completely disregarding the fact that many of the Realms in Arcadia are [[spoiler: [[GeniusLoci The True Fae themselves]]]].
* ''TabletopGame/BeastThePrimordial'' has the Lairs, individual to each Beast, an otherspace that is reflective of their own power (the higher their PowerStat goes, the more chambers it gains) that can be entered through any doorway.
* Pretty much everywhere outside of Illusion in TabletopGame/{{Kult}}. Weird geoscapes are the least of your worries. Gaia is the primal world where even the ''earth'' can get hungry and swallow people, Metropolis is a city filled with lunatics and Inferno is a classic {{hell}}.
* The Mad City of TabletopGame/DontRestYourHead is pretty much made of this trope.
* ''TabletopGame/{{Exalted}}'':
** The Wyld, in which reality as we know it pretty much stops working. Divided into the Bordermarches, the closest regions to normal reality, which are only mildly weird, the Middlemarches, where the laws of physics cease to be reliable and movement and distance are [[TheoryOfNarrativeCausality based more around narrative conventions than concrete measurements]], the Deep Wyld, where reality is officially [[RealityIsOutToLunch Out To Lunch]], and the Pure Chaos, which isn't so much a location as it is the unshaped, incoherent chaos outside of the universe.
** And then there are the Shadowlands, sites of past atrocities and mass murder where the border between Creation and the Underworld is just a bit thinner. Regaining Essence is hampered (unless you're a creature of the Underworld, in which case it picks up by comparison), ghosts can get around more easily, and improperly buried bodies tend to rise as zombies.
** Several of the Primordials/Yozis [[GeniusLoci are this]] as well. Things like the local geography, physical laws, and even time flow are often at the whims of the Titan that is the world. The most notable are Malfeas (the Demon King/City whose body acts as the prison of his fellows, and consists of multiple layers that constantly change shape and correspondence, and all inexplicably have the green sun of Hell right above them), Cecylene (the Endless Desert who is accessible from every layer of Malfeas and always takes ''exactly'' five days to cross) and Autochthon (who needed to deliberately modify his world body to make it habitable; the deeper parts of it show the reason for this).
** There are even a few places in Creation that work like this. One is the Well of Udr, overseen by [[NamesToRunAwayFromReallyFast the Dowager of the Irreverent Vulgate in Unrent Veils]]. It's a nexus of all possible dimensions where the strata of potential worlds collide and crash against one another, occasionally disgorging impossibilities. It's very tricky to get anywhere within its vicinity and hold onto your marbles, let alone stare into it. It's from here that the Dowager retrieved [[TheEndOfTheWorldAsWeKnowIt the Great Contagion]].
** The Elemental Poles, too, each of which is an unending font of elemental power. The trees at the Elemental Pole of Wood are infinitely tall.
* The Umbra from the ''TabletopGame/OldWorldOfDarkness'' folds in itself any sort of alternative reality and other states of being. And one has to step ''sideways'' to reach it. Sideways to reality as a whole. Furthermore, different places in the Umbra have their own laws, and the further one gets from Earth, the weirder and more hostile the worlds become, until the Deep Umbra is reached. Things are just plain ''wrong'' there. And very, ''very'' inhospitable for almost any type of earth-like life.
** And then there's the [[NamesToRunAwayFromReallyFast Black Spiral]], located in Malfeas (the Shenti of the Wyrm). Depending on [[CanonDiscontinuity which game in the cobbled together setting]] you happen to be operating in, the Black Spiral is either in [[TabletopGame/WerewolfTheApocalypse the Deep Umbra]], [[TabletopGame/ChangelingTheDreaming the Dark Dreaming]], [[TabletopGame/WraithTheOblivion the center of the Maelstrom]], or is either a convergence or a place that has doorways to all three. Put simply, it's Hell, but of course it's not that simple and entire books have been dedicated to describing, expanding, contradicting and redefining what the Black Spiral actually is. ''TabletopGame/WerewolfTheApocalypse'' describes it as the tormented mind of the Wyrm itself. There are even allusions that it is the dessicated husk of ancient Malfeas from ''TabletopGame/{{Exalted}}''. It breaks, reshapes and fundamentally corrupts anyone unlucky enough to find themselves there, and we're talking mentally, physically and spiritually, all at once. It is the home, seat of power, [[GeniusLoci dying body]] and [[AndIMustScream prison]] of the Wyrm, the primordial force of entropy in the setting's universe. One tribe of werewolves are called the [[NamesToRunAwayFromReallyFast Black Spiral Dancers]]. Guess what they do for an initiation rite?
* The Shadow Realm of the ''TabletopGame/NewWorldOfDarkness'' is more a DarkWorld. But if you go deep enough, you get to the parts of the Shadow Realm taken over by lords among the Spirits, and then the rules disappear.
* ''TabletopGame/{{Warhammer 40000}}''.
** Aside from the mentions in the literature section above, ''everything'' in the Eye of Terror ends up this way, as well as the Maelstrom (basically a mini Eye of Terror that doesn't even have the decency of an explanation of how it started). Any place a Warp Rift is opened starts to slowly turn into one of these, and if the rift is left unchecked it can end up turning the entire planet into a [[WorldOfChaos Daemon World]]. And that's just what happens when a ''tiny fraction'' of the Warp leaks into the real world...
** The Dark City of Commorragh, home of the Dark Eldar, is also an example, being an enormous collection of realms located inside the Webway (a network of warded tunnels in the Warp), linked together with portals. It's basically Escher on crack and populated entirely by sadistic murder-elves. To make matters worse, in some parts the wards that separate the Webway from the Warp have become weakened, leading to things like districts where shadows come to life and things from outside reality lurk.
** Necron tomb worlds are examples of non-Warp related eldritch locations. The Necrons' mastery over science allows them to create spaces that follow a higher order of geometry than we're used to, resulting in things like buildings that are bigger on the inside.
** Even Eldar Craftworlds are such. They are not planet sized spaceships, but rather entire fleets that gathered together for mutual protection, linked by gates and warps that are tangental to the Webway as a whole. Any given door doesn't open onto whatever's on the other side, but rather to wherever you are wanting to go in the Craftworld itself. On top of this, the physical linkages joining the Craftworld is made from, effectively, psychic powers turned into a solid, called Wraithbone - and acting as a conduit for the souls of every Eldar whose Soulstone was recovered. And at the core of each Craftworld is an area called the Dome of the Crystal Seers. The apparent statues in here aren't - they're the solidified bodies of the greatest farseers of the craftworld, converted into solid wraithbone.
* ''TabletopGame/MagicTheGathering'':
** The locations associated with its resident {{Eldritch Abomination}}s, the Eldrazi; in particular, a combination of solitude and proximity to the Eye of Ugin, which sealed the Eldrazi within the plane Zendikar, cost the planeswalker Sarkhan Vol his sanity for a time, and it wasn't until several months after leaving that he had fully recovered.
** Innistrad isn't as bad as Zendikar [[spoiler:until Nahiri summons Emrakul to it]] but there's clearly something ''off'' with its moon. The moon of Innistrad is a powerful source of mana of multiple types and is responsible for the existence of Innistrad's various supernatural beings: angels, werewolves, [[spoiler:and the vampires since Edgar Markov became the first vampire by drinking angel blood]]. The Helvault, a nigh indestructible prison for demons, was created from a fragment of the moon. [[spoiler:The moon itself eventually becomes Emrakul's prison.]]
* In ''TabletopGame/{{Nephilim}}'', Selenim are capable of creating Realms, pocket universes that exist according to their will, which turn out like this trope.
* Most of the ''TabletopGame/JAGSWonderland'' setting has this in spades. There are eight layers of reality, referred to as "Chessboards." You live on Chessboard Zero. Chessboard One is more or less identical, except everyone's kind of nuts. Chessboard Two is a run-down, dilapidated DarkWorld. Chessboards Three through Six are a sliding scale of CloudCuckooLand and this trope. And Chessboard Seven can barely be called reality by any stretch.
* ''TabletopGame/ArkhamHorror'' allows the players to visit the locations from H.P. Lovecraft's mythos, like the Plateau Of Leng, Yuggoth, and R'lyeh.
* In ''TabletopGame/{{Dragonstar}}'' there is a large region of space outside Imperial space known as the Dark Zone. Few who venture into it ever return, but the few who do speak of darkness and terror. It's also the setting's counterpart to the Far Realm in that it's the home of mind flayers (their original home, it is speculated) and other aberrations.
* In ''TabletopGame/BleakWorld'' this is what the Death Beyond Death is, if a ghost dies they go to a place where they are in constant pain, but can never gain the release of going insane. The whole area is guarded by [[EldritchAbomination The Caretaker]] which is liquid field of darkness filled with constantly disappearing eyes and mouths
* In the game ''Magical Burst'', Youma, the creatures {{Magical Girl}}s fight, frequently surround themselves with a distortion in the tapestry of the world called a Nightmare. For most people, this manifests as a vague feeling of dread, owing to how {{Muggles}} cannot even ''perceive'' Youma or their influence, much less hurt them. For Magical Girls and those attuned to magic, the Nightmare appears as an increasingly surreal region of distorted reality, getting weirder and weirder as one nears the Youma.
* The titular setting of ''TabletopGame/BetrayalAtHouseOnTheHill'' always has a random layout, and can have things such as walls that devour you and spit you out elsewhere.
* The cosmos of ''TabletopGame/{{Nobilis}}'' is pretty much made up of Eldritch Locations, all of which run on their own set of rules - ''including'' mundane Earth, which is a fantasy the Earth created for itself after the trauma that destroyed the dinosaurs, a way for it to deny the existence of karma and thus the belief that it deserved that trauma. It's self-maintaining, self-rationalising... and overstretched, as it's getting far too complex to sustain.
[[/folder]]

[[folder:Tropes]]
* The SugarBowl is a strange form of this. It may be depicted as a genuinely nice place, or as it was in the article. However, there's no denying that a place with licorice trees and structurally sound buildings of candy would belong here.
** Likewise, ''VideoGame/AnimalCrossing'' definitely exists in one of these [[FridgeLogic if you think about it hard enough]]. This has been well-documented in many {{Dark Fic}}s.
* The ClownCarBase also fits this trope in a way, especially when the trope is {{lampshade|Hanging}}d, revealing it to be not just a perspective oddity, but a genuine physically disproportionate building.
* A LevelAte is a place where terrain is GiantFood, often a humorous version of this sort of thing.
* Many {{Lost World}}s are this in a nutshell.
* A DarkWorld can function as an Eldritch Location when it's explicitly evil or "wrong", but a few morality neutral Dark Places are natural "night side" reality counterparts to our own.
* A PlaceBeyondTime is this by its very nature.
* An EldritchStarship can easily be an Eldritch Location with a hyperdrive.

[[folder:Video Games]]
* ''Franchise/ShinMegamiTenseiPersona'':
** The series in general has a more benevolent but still bizarre example in the Velvet Room, a room covered ceiling-to-floor in blue velvet that exists outside of time and space, changes appearances with each game, and sometimes isn't even a room (in ''3'' it's an ever-ascending elevator car, and in ''4'' it's a limousine traveling through space.) All of its denizens - the master, Igor, the pianist and singer in the first two games, the painter in ''2'', Elizabeth and Theodore in ''3'', Margaret in ''4'', and Caroline and Justine in ''5'' - are all AmbiguouslyHuman.
** The original ''VideoGame/{{Persona}}'' has a slew of them, courtesy of most of the game being set in [[spoiler:a parallel dimension formed from the thoughts of IllGirl Maki Sonomura, courtesy of a device called the DEVA System]]. The most prominent in the game would be [[spoiler:Avidya World, the embodiment of Maki's darkest thoughts and the VeryDefinitelyFinalDungeon]]. ''Your own high school'' can also get turned into one if you partake the optional Snow Queen Quest instead: if you find a mask inside the school's gymnasium, the spirit inheriting it turns it into a frozen ice palace surrounded by three arcane towers, and you have to trek all three and collect twelve mirror shards in order to break the spell.
** While most of the dungeons in the ''VideoGame/{{Persona 2}}'' duology are set in the real world, [[YourMindMakesItReal the ever-omnipresent ability to make rumors into reality]] add an extra layer of strangeness to them all. The most straightforward example is [[spoiler:Monado Mandala, Nyarlathotep's domain,]], which you only see in the second half of the duology (''Eternal Punishment''): it exists in a space-like area, with pathways and mandalas of light serving as its sole building bricks.
** ''VideoGame/{{Persona 3}}'' has Tartarus (pictured above), an [[ChaosArchitecture ever-changing]] tower that only exists during the Dark Hour, and acts as a pathway from the world of Death and the Collective Unconsciousness from which humanity's Shadows can manifest. [[UpdatedRerelease FES]] adds the Abyss of Time as its inverted twin.
** ''VideoGame/{{Persona 4}}'' has rather the creepy TV World, which once again, is the Collective Unconsciousness being forced to manifest via the "mind" of mass media. [[spoiler:Subverted in the True Ending, where lifting the final veil of deceit from mankind's heart turns the Collective Unconsciousness itself into the GhibliHills.]]
** ''VideoGame/{{Persona 5}}'' has the Palace, a region inside the [[MentalWorld Collective Unconsciousness]] that can create a mirror of reality based on the warped desires of humans, and you can only get there with a mysterious phone app. The underground maze of Mementos serves as the Palace for most of humanity, but those with especially potent, twisted desires can create their own palaces that reflect their state of mind, much like the dungeons of the Midnight Channel in ''Persona 4.'' The creators of the more unique palaces serve as the major bosses for the game.
* Bacterian, the BigBad of the ''VideoGame/{{Gradius}}'' series qualifies: He is a GeniusLoci HiveMind that uses psychic powers to control his fleets. Every time he's defeated, the pieces of him regenerate to form new Bacterians. Gofer, Venom, Zelos, and some other large Bacterians also qualify.
* The Pfhor ship of ''VideoGame/{{Marathon}}'' seems to be mostly organic, with green liquid all over the place. The gravity is low, too. The creepy music doesn't help either. ''Marathon's'' game engine actually ''encourages'' non-Euclidean level design because of the way it implements overpasses. Several levels have passageways that pass through each other as an intentional MindScrew, and some third-party mapmakers have taken it to a very confusing extreme.
* ''Franchise/SilentHill'' features a weird variation of this trope through the eponymous town, which may cross over with, unusually, EldritchAbomination and GeniusLoci. Though its exact nature is [[MindScrew very much up for debate]], it appears to be abandoned and shrouded in fog, day and night come randomly, and a nightmarish [[DarkWorld "otherworld"]] version of the town lurks beneath the surface and can overtake you at any moment. The otherworld draws its form [[SelfInflictedHell from people's minds]], sometimes [[PsychologicalTormentZone the protagonists]] and sometimes [[RealityWarper another character entirely]]; quite a few [[EpilepticTrees epileptic forests]] have grown from trying to explain it all. It's worth pointing out that DJ Bobby Ricks, one character in ''VideoGame/SilentHillDownpour'' has pointed out that the town has 'rules,' and it is not keen on people disobeying it. If the town wants you to stay inside, if it wants you to learn something, you will. Possibly for eternity, as one character has been stuck there, delivering mail to parties unknown (possibly from the town itself) for 200 years. Even the apparent deity or demon worshiped by the town's resident cult, [[ScaryAmoralReligion The Order]], might just be the town acting upon the cult members' beliefs and desires.
* ''VideoGame/{{MOTHER}}''
** In ''[[VideoGame/CognitiveDissonance MOTHER: Cognitive Dissonance]]'', you are sent into one of these by Niiue to distract Giygas, where everything is red, there's chaotic forces of PSI, and the alien himself waiting in the center of it all with the Devil's Machine.
** In ''VideoGame/EarthBound'', once the Devil's Machine is turned off, it's implied that Giygas might just be huge and dimension-warping enough to be not just an EldritchAbomination, but one of these in his own right. And before that, Ness and Jeff get to visit Moonside, which also qualifies.
** ''VideoGame/{{Mother 3}}'' has the Empire Pork Building, which is an unusual sort of eldritch location. Every floor you visit seems normal in its own right, at least as far as the Mother series goes. A lake full of hippos, a hall full of bathrooms, a construction site, etc. But they're all so disconnected and irrelevant to each other, and supposedly each one is the 100th floor.
* ''Franchise/TheLegendOfZelda'':
** The various incarnations of the LostWoods in the ''Zelda'' games: they either turn off your minimap, making navigation extremely difficult, or in ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle of Seasons]]'', one place is even completely off the map, plus the place where Like-Likes fall from the sky. In ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' it's implied that anyone who isn't of TheFairFolk would tend to become hopelessly lost, eventually turning into skeletal imps doomed to haunt the forest forever.
** ''VideoGame/TheLegendOfZeldaSpiritTracks'' has the final area, the Dark Realm. Accessed through a dark portal that can only be found with a magic compass, it basically looks like Van Gogh's ''Starry Night'' in a black hole. Beneath the train tracks is some kind of strange, smoky/watery "ground" that gives way to a completely different landscape right beneath it.
** The setting of ''VideoGame/TheLegendOfZeldaMajorasMask'' is a pseudo alternate dimension called Termina, with several oddities (like the physics of Stone Tower Temple, as well as the SurrealHorror elements involving the Moon and the distinct regions) that violate many logics. The fact that the game's titular villain is a reality warping, psychopathic EldritchAbomination contributes to this as well.
* The inner sections of the Pyxis (A.K.A the Box) from ''VideoGame/CliveBarkersJericho''.
* ''VideoGame/{{Chzo|Mythos}}'' is both this and an EldritchAbomination, a pain elemental who satiates himself with tortured victims trapped inside his labyrinthine corridors for all eternity.
* The interaction of {{Hyperspace|IsAScaryPlace}} and Pathspace in ''VideoGame/ImmortalDefense'' produces one of these. From Pathspace, Hyperspace looks like a twisty path across a 2D plane, and from Hyperspace, Pathspace is the home of vindictive demigods who rain psychic death upon unwary travelers. [[spoiler: The ''protagonist'' is one of these demigods.]]
* ''VideoGame/DwarfFortress'':
** [[http://www.bay12forums.com/smf/index.php?topic=61507.msg1400676#msg1400676 The Adamantine Spire]], a.k.a. the Adamantine Space Elevator. The weirdest part is that even when other people tried to recreate it using the same worldgen seed, it didn't show up. Current theories are that it's due to [[GoodBadBugs interference from old save data]].
** FridgeHorror: Considering what adamantine veins like the spire usually [[TheLegionsOfHell contain,]] it looks like whatever counts as Heaven in the Dorf 'verse is in for some serious [[UnusualEuphemism Fun.]]
** Some of the more convoluted succession forts such as ''LetsPlay/{{Battlefailed}}'' become this. Battlefields had the temporally locked dwarves in the arena, Headshoots had the room outside of space, etc.
** And then there's the evil biomes. Rains of blood and FogOfDoom that causes any living thing exposed to it a horribly painful death if they're lucky or turns them into a [[HumanoidAbomination thrall]] if they're not, eyeballs and tentacles growing out of the ground, a 50/50 chance of anything that dies there spontaneously reaminating into a zombie if the body isn't [[ChunkySalsaRule thoroughly destroyed]] and native wildlife that would make [[VideoGame/{{Doom}} Doomguy]] feel right at home.
* ''Franchise/{{Pokemon}}'':
** The Distortion World from ''[[VideoGame/PokemonDiamondAndPearl Pokémon Platinum]]'' falls under this. Floating masses of land in a giant vortex, giant plants that sprout randomly out of nowhere, disappearing platforms, and waterfalls that float up are just a few features to be found. And that the ''only'' thing living in there is the EldritchAbomination known as Giratina. There's also the immense GravityScrew of the Distortion World. The waterfall isn't the only thing that goes the wrong way there; the Distortion World is the ''only'' place in the ''whole main series'' where you navigate by jumping onto those floating platforms and ''walking sideways''. It's also impossible to ride your bike there.
** Ultra Space, the home dimension of the Ultra Beasts from ''VideoGame/PokemonSunAndMoon''. We don't see too much of it, just a multicolored barren cavern, lit up despite the absence of any apparent light source, filled with various Nihilego (read:toxic parasitic jellyfish made of shapeshifting glass) floating around and occasionally phasing in and out of existence. The characters comment that the air feels strange and it's hard to breathe properly. The Rotom Pokedex, which is otherwise always chatty and displays a map of the area, is completely silent and its screen is filled with static, completely inoperable.
** In ''VideoGame/PokemonUltraSunAndUltraMoon'', you see more Ultra Spaces and you can even fight the Ultra Beasts on their Home Turf. From what the trailers have shown, Kartana (read:living origami who can cut through steel) resides in a strange forest, Buzzwole (read:muscular humanoid mosquito) resides in one of the least eldritch of them as it looks more like a jungle in broad daylight (though that may invoke [[DaylightHorror another trope]]) and Xurkitree resides in what looks like the inside of a chaotic machine.
* The Dark Rift from ''VideoGame/SkiesOfArcadia'', a high-pressure storm system that can't be crossed the way regular rifts can even with a fully-upgraded ship and remains even after the other rifts have calmed. Inside it is an alien landscape full of corridors that connect in odd ways, strangely-oriented landmasses, and plants and creatures very much unlike the ones seen anywhere else in the game. At its heart is a moon stone that doesn't match any of Arcadia's 6 moons.
* ''VideoGame/{{Skullgirls}}'':
** Gehenna, a WombLevel set before a lake of blood whose background features several eyes imbedded into the level that follow the characters as they fight. [[HellIsThatSound Yes, that's screaming you can hear in the soundtrack.]]
** Nightmare Crest is a twisted version of the familiar Maplecrest stage that acts as a setting for the game's BattleInTheCentreOfTheMind stages - the surroundings are muted and greyscale, the people that are normally bright and colourful on Maplecrest are formless shades with glowing white eyes and while the black leaves are frozen in mid-fall, the sky above is a rapidly-swirling red and purple storm.
* ''Franchise/{{Castlevania}}'':
** It's an Eldritch Location and houses several {{Eldritch Abomination}}s to boot. The discrepancy that crops up between the games is {{lampshade|Hanging}}d and {{handwav|ing}}ed with a comment that the castle is "[[ChaosArchitecture a creature of chaos]]." The castle can take many shapes and forms, picking and choosing when and if it wants to follow the laws of physics.
** In ''VideoGame/CastlevaniaSymphonyOfTheNight''), the whole castle ''has an inverted duplicate'' revealed halfway through. You and the monsters fall towards and walk around on the ceiling. All the furniture is still on the floor. It is never explained why a second castle just appears out of the clouds, nor why it's upside down. And then there's the two mirrored split castles in ''VideoGame/CastlevaniaHarmonyOfDissonance'', which are somehow both the extension of Maxim's will.
** Dracula's demon castle continues to follow tradition in the [[VideoGame/CastlevaniaLordsOfShadow2 Lords of Shadow]] subseries, with that twist that an entire city gets built onto the ruins at one point. While being on top of the castle usually isn't a problem, it does mean that someone can occasionally walk right outside of their office and wind up right in the seat of Dracula's power.
* ''Franchise/KingdomHearts'':
** Both [[VeryDefinitelyFinalDungeon final levels]] of ''Franchise/KingdomHearts I'' and ''II''. The one from [[VideoGame/KingdomHearts the first game]], appropriately titled The End Of The World, is basically the remains of any and every world destroyed by TheHeartless, and the one from [[VideoGame/KingdomHeartsII the second game]], The World That Never Was is a dark city overrun by Heartless overlooked by the warped castle that is the headquarters of Organization XIII, and its ''[[WeirdMoon moon]]'' is [[MacGuffinLocation the heart of reality itself,]] [[TitleDrop Kingdom Hearts]] (or at least, a functional replica).
** In fact, the concept of the worlds makes them Eldritch Locations: they are apparently separated, but are described as sharing the same skies. All the worlds used to be one large world, but it was shattered in the Keyblade War, leaving only shards behind, forever separated by metaphysical barriers that few can traverse.
** The Realm of Darkness is its own twisted version of reality. As the name suggests, it's pretty dark, much of it seemingly made up of gray rocks with cracks out of which ghostly blue light faintly shines. There is no sky, no horizon, just pure blackness. Seemingly no living things other than the Heartless (if they count as such). But the most disturbing thing about it is that ''time'' doesn't flow in the Realm of Darkness. Characters who are trapped there do not age and do not sleep, and have no way of marking the passage of time. [[spoiler:Aqua is surprised to hear that she's been trapped in there for ''over ten years'' from the perspective of everyone else.]] And the worlds that fall to darkness? They get trapped in the Realm as well, transformed into twisted caricatures of themselves floating in a void that only barely obey the laws of physics.
* ''VideoGame/ShinMegamiTenseiStrangeJourney'' has the [[DarkWorld Schwarzwelt]]. It is effectively a [[NegativeSpaceWedgie void]] over Antarctica where [[HellGate demons appear]], overwriting Earth with their own reality. The Investigation Team's mission is to analyze and nullify the Schwarzwelt before it can consume the entire world. The game over screen shows what happens if your character dies...it ain't pretty. The fun part is that the UN sent cameras into the Schwarzwelt during the planning stages...and ''nobody'' believed the results (one of them was a ''shopping mall''). Turns out they were all accurate (but you don't want to eat the food in the shopping mall...).
* ''[[VideoGame/ShinMegamiTenseiIIINocturne Shin Megami Tensei: Nocturne]]'' mostly takes place within the Vortex World, a chaotic, demon infested realm that the Earth reverts to when it comes time for a new world order to be decided. Naturally, it's up to you to shape it as you see fit. For bonus points, it's a truly literal form of TokyoIsTheCenterOfTheUniverse.
* And in ''VideoGame/ShinMegamiTenseiIV'', we have the final dungeons for Law and Chaos, respectively: Purgatorium and Lucifer Palace. The Monochrome Forest also counts, as well as the various Demon Domains littered around Tokyo.
* Xen, the "border-world" from ''VideoGame/HalfLife1''. It seems to consist of a bunch of small rocky islands floating in the middle of a greenish void, and yet apparently has gravity independent of those islands and a breathable atmosphere. It's also inhabited, although [[AllThereInTheManual the fluff]] indicates that the current inhabitants are not native to the dimension, and came from someplace else.
* Every time you fly through Bydo Dimension in ''VideoGame/RType'', especially the MindScrew territory of the final stages of ''Delta'' and, well, ''Final''. To put in specific terms, the Bydo Dimension in ''Delta'', which is depicted in the picture above, looks like a twisted version of our world with babies encased in crystals, upside-down buildings, huge strands of DNA, and a weird forest of Bydo Trees. The Bydo Dimension in ''Final'' is an abyss full of fluid inhabited by eyeballs and the creature implied to be the real source of the Bydo. The Bydo Tree forest bit also appears in ''Final'' as a hidden stage. There is also a stage in ''Final'' that takes place in a weird dimension where there is only the player, a slug Bydo named Nomemayer, and particles of light that can turn anything and anyone into a Bydo. And there's Anti-Space, a dimension ''created'' by some Bydo guys named Gridlock.
* On the final floor of ''[[VideoGame/{{Dgeneration}} D/Generation]]'', what once looked like an ordinary office building (albeit with hyperactive security measures) suddenly turns into a bizarre surreal nightmare thanks to the title entity. There's also a headless guy.
* ''Franchise/DragonAge'':
** The Fade, the place people (except dwarves) go when they dream, full of spirits and demons and doubling as Heaven, Hell and everything in between. Characters are trapped in their own "mini-Hells" ([[IronicHell reflecting their own lives]]), the sky is full of floating mountains (heavily implied to be other, infinitely large hells) and the [[{{Hell}} Black City]] is visible wherever you go.
** And in the DLC ''Witch Hunt,'' Morrigan implies that beyond the Fade there are places that are even stranger where [[spoiler: she's keeping her Demon Baby safe from her evil mom.]]
** Amgarrak Thaig, the titular location of ''Golems of Amgarrak'' is definitely one, protected from the outside by a maze of shifting mist and having Lyrium Wells that were designed to phase-shift people into alternate versions of the Thaig in order to better safeguard its secrets.
** The sequel has [[spoiler:Kirkwall. Yes, that's right: the main setting. It's subtle, though; you can go through the whole game just thinking the whole place is a [[CrapsackWorld Crapsack City-State]], but certain notes you find indicate that not only is the Veil unnaturally thin over the entire area, entire neighborhoods are constructed in the shapes of blood magic sigils, there are likely lakes of blood beneath the streets that still haven't dried, but demons are actively drawn to the place like flies to the point where they occasionally hunt non-mages because ''there's too much competition''. And that's ''before'' you factor in [[SealedEvilInACan Corypheus']] [[TheCorruption corrupting]] presence from his Grey Warden Prison in the nearby Vimmark Mountains.]] It - or very nearby - is actually where [[spoiler: the magisters entered the Black City (sacrificing hundreds of slaves in a blood ritual in the process) and were transformed, like Corypheus, into darkspawn, causing the Blights.]]
** The [[spoiler: Primeval Thaig]] is definitely one, [[spoiler: built by prehistoric Dwarves that worshipped a pantheon of deities, constructed using magic thus giving it some degree of AlienGeometry, posessing a unique form of Red Lyrium running throughout the structure itself and inhabited by creatures like the Profane that Varric claims were supposed to be ''myth''. It was also the location where Hawke and company first encountered the [[ArtefactOfDoom Lyrium Idol]]]].
** In an older Creator/BioWare example, the Spirit World of ''VideoGame/JadeEmpire'' is similarly weird.
* ''VideoGame/{{Homeworld}}: Cataclysm'''s Beast is said to come from "Outside".
* The NES game ''VideoGame/TheMagicOfScheherazade'' has the EldritchAbomination Goragora [[SealedEvilInACan trapped in ancient times]] in the "Dark World" (not to be confused with a DarkWorld), and the villain threatening to release it once more. He eventually learns the hard way that EvilIsNotAToy, and begs the heroes to enter the Dark World and keep it from escaping. Beyond the gate and past the PointOfNoReturn, the VeryDefinitelyFinalDungeon looks like a starswept black abyss with walls and columns made out of transparent bubbles.
* The GBA and PSP remakes of ''VideoGame/FinalFantasyI'' have the four special dungeons that change floor permutation with every visit. Furthermore, some of these floors have environments that should not be able to exist in a subterranean environment, such as overworlds, {{Floating Continent}}s, and thriving towns that look just like the ones on the surface, ''complete with shops and inns''.
* In ''VideoGame/FinalFantasyII'', [[spoiler:the Jade Passage and Pandaemonium]].
* In ''VideoGame/FinalFantasyIX'':
** [[spoiler:Terra, a parasitic other planet, actually inserted itself into Gaia long ago and is feeding off the planet from the inside.]] Creepy.
** Another present in the same game is [[spoiler: Memoria, a world formed from the collective memory of the entire planet.]]
** The Hill of Despair where the party fights Necorn which is apparently the [[spoiler: Afterlife.]]
* ''VideoGame/FinalFantasyV'' has the [[VeryDefinitelyFinalDungeon Cleft of Dimensions]], which is a patchwork of areas earlier swallowed up in the Void and home to many {{Eldritch Abomination}}s including the game's two NintendoHard {{Bonus Boss}}es. The UpdatedRerelease added the [[BonusDungeon Sealed Temple]], home to even more {{Bonus Boss}}es, including the HumanoidAbomination who the legendary weapons were crafted specifically to fight.
* ''VideoGame/FinalFantasyXI'' has a few that qualify, and they all tend to follow the "islands floating in nothingness" style:
** The Promyvion areas appear to be corrupted, shadowy versions of other existing areas, topped off with haunting music and freakish looking monsters.
** The Walk of Echoes is an area of disconnected structures floating in nothingness. [[spoiler: It pretty much exists outside of time, and Atomos himself can be seen in the sky at all times.]]
** The added Provenance areas, [[spoiler: which are described as being the place where the source of all life comes from.]]
* Although featuring fewer locations than one might expect, ''VideoGame/FinalFantasyXIV'' still features some notable examples, especially those found in the ''Heavensward'' expansion. Perhaps the most obviously eldritch is [[spoiler: the Aery, Nidhogg's lair, which is a ruined Avalonian city held together in a storm of aetheric energy fueled by the dragon's blinding rage.]]
** The strangest location has to be the Palace Of the Dead (making a cameo from TacticsOgre); accessible only through a strange portal in the Black Shroud, the Palace of the Dead is an ever shifting maze filled with monsters, traps, and strange magical items that only seem to function within. The entire palace is filled with a gloom that saps the strength of anyone who enters, reducing them to Level 1 and rendering their equipment useless. Only by condensing one's life force into weapons and armor made of magic can one hope to survive. What's even stranger is how, while decending in the palace, players will rapidly gain levels to the point of exceeding their job level back in the 'real world'. Prior to Stormblood, this even meant learning spells and abilities meant for max level characters while still being low leveled in the "real world". The deeper you go in the Palace, the stranger things become; eventually falling apart into a series of pathways in a misty white void. The 200th floor features [[spoiler:a tranquil looking bench underlooking a tree, in a place completely devoid of enemies. Some players have joked that this is the Palace inviting you to be it's latest denizen. Thankfully it doesn't object if you refuse.]]
* The inside of [[EldritchAbomination Sin]] in ''VideoGame/FinalFantasyX''.
* In ''VideoGame/{{Xenogears}}'', [[spoiler:Deus, already an EldritchAbomination, becomes an enormous EldritchLocation in its own right.]]
* The Dead Sea from ''VideoGame/ChronoCross''. It's the site of a massive TimeCrash, where the canceled BadFuture from ''VideoGame/ChronoTrigger'' tried to reassert itself over Chronopolis. Waves of water, forever frozen in time, wash over the wreckage of the city, and at the heart is the Tower of Geddon, a conglomeration of locations from said canceled timeline haphazardly mashed together. Much later, you also go to the Darkness Beyond Time, where cancelled timelines are sent [[spoiler:and where the Time Devourer lurks]].
* Its predecessor ''VideoGame/ChronoTrigger'' already had the [[PlaceBeyondTime End of Time]], the place where all possible time lines meet. As far as eldritch locations go, it's actually fairly harmless. The UpdatedRerelease added a few more such as the [[BonusDungeon Dimensional Vortexes]], areas where time and space are essentially broken. The Darkness Beyond Time also makes an appearance.
* In ''VideoGame/WildArms2'', [[spoiler:the Encroaching Parallel Universe "Kuiper Belt" is one of the most terrifying examples yet]].
* In the original ''VideoGame/PhantasyStar'' series, the very Algol star system it takes place in is an enormous lock for a dreadful SealedEvilInACan. And the lock isn't exactly completely intact.
* The titular planet in ''VideoGame/{{Albion}}'' looks like some alien world with primitive civilizations at first. Until it is revealed that it operates under completely different laws the Earth does. [[spoiler:The fact that it's actually a sentient (benevolent) being, has something to do with it]].
* The tunnels under ''VideoGame/PathwaysIntoDarkness'''s pyramid are actually the nightmares of a catatonic EldritchAbomination made real.
* Several places in the ''VideoGame/{{Warcraft}}'' universe qualify.
** Chief among them is Outland. It was formed when the planet Draenor was torn apart by multiple interdimensional gateways being opened on the surface. It's now a continent with several different ecosystems, some of which are healthy and normal, or at least, [[PatchworkMap as normal as the rest of this universe]]. However, the [[FloatingContinent continent]] is surrounded by, rather than an ocean, an edge, and if you walk off it you fall into nothingness. It also has an AlienSky, which is sunless but otherwise mysteriously normal in some zones, but looks like energy cascading through space in other places. In several places there are {{Floating Island}}s, some of which have water perpetually falling off them with no source.
** The Netherstorm. Not only is it even more surreal than the rest of Outland, being just a collection of massive floating rocks instead of a single land mass, no one knows where it came from. Every other zone has a clear analogue on Draenor but the Netherstorm doesn't.
** The Maelstrom. A eternal whirlpool full of unstable energies surrounded by an eternal hurricane that was formed when the Well of Eternity was destroyed. The black dragon Deathwing used it as a portal back to Azeroth, almost causing the world to blow up. The constant attention of several powerful shamans is required to keep the world from falling apart through it.
** Deepholm. It can be reached by flying into the Maelstrom. It is the home of earth elementals and other creatures native to the elemental plane, so it's not ''supposed'' to be comfortable to flesh-and-blood creatures like playable races. It is a massive cave with a rock-based ecosystem, rock pillars that float in the air, and spires that regularly explode and reform. Most of the elemental planes are odd like this, but with another element in the place of rock.
** Karazhan is a large black tower in the mostly empty Deadwind Pass. It was once home to Medivh, The Last Guardian, and sits atop a point where every ley line (think veins, but instead of blood it's magic) in the entire world intersects. Time itself gets lost within Karazhan, allowing visions of past, future and other worlds to pop in and out unexpectedly. One of Medivh's theories is that the Deadwind Pass was formed because someone would eventually build a tower there, rather than the tower being built where the Pass was. Also, there is an inverted Karazhan under the main one, and the main one exists in at least two parallel universes at once. There's also the odder features inside and around the tower.
* The World of Mammon in ''VideoGame/{{Quest 64}}''. The environment drastically changes with each transition, doors never lead to the same place twice, the sky is always the wrong the color, and the music is creepy as heck. The inhabitants are just as unnerving: among them are [[LivingStatue Living Statues]] that have more than a passing resemblance to [[Series/DoctorWho the Weeping Angels]]. Of course, the entire place is the prison/domain of a demonic EldritchAbomination.
* ''VideoGame/{{Minecraft}}'' has a couple of these:
** The Nether is a [[HyperspaceIsAScaryPlace deliberate example]]. Once you finish the mining tech tree and craft a diamond pickaxe, you can build an obsidian HellGate and enter a skyless world filled with steep cliffs, lava lakes, and giant jellyfish that spit fireballs at you while flying out of reach of your arrows. Not only will your compass spin around aimlessly, so will your watch. However, any distance traveled inside the Nether is multiplied by eight once you return to the normal world, so it can be used to travel long distances relatively quickly, once you finish digging tunnels and building bridges.
** The End, a single barren island floating in an infinite void. It's home to the Endermen, and can only be accessed by portals deep in underground ruins... and can only be exited by defeating the [[FinalBoss Ender Dragon]].
** An [[MinusWorld unintentional version]] of this is the Far Lands. In the pre-release versions of Minecraft, travelling roughly 12 million meters in any one direction makes the game generate areas like [[http://hydra-media.cursecdn.com/minecraft.gamepedia.com/c/cc/12550821line.png?version=6d6925e5d08789a5400fcd256252a8dd this]], in addition to huge amounts of lag and "stuttery" movement. Travel even farther, and around 32 million meters, physics and lighting just stop working altogether. The Far Lands were acknowledged by the creators, who [[AscendedGlitch planned to keep them in the game]], but changes to the way terrain is generated effectively removed them before release.
** ''VideoGame/{{Thaumcraft}}'', a popular GameMod, contains a more traditional example, called the Outer Lands. You get there by [[spoiler:performing a ritual called "Opening the Eye" on a floating Eldritch Obelisk]]. When you arrive, you'll find [[spoiler:a dark maze filled with Eldritch Abominations, with a boss at the end]].
* ''VideoGame/TheBreach'' starts off on an ordinary spaceship, but towards the end things start to ''shift'' into a mountainous region filled with yellow mist and glowing glyphs.
* ''VideoGame/MassEffect2'' has [[spoiler:the derelict Reaper, which can still indoctrinate despite being dead for ''37 million years'', a not-so-derelict Collector vessel and finally the Collector Base, an immense space station located in the accretion disc at the heart of the galaxy, which serves as TheVeryDefinitelyFinalDungeon. The vessel is even creepier than the base itself since in the latter, you are almost continuously under attack, while in the former, about the first two thirds of the mission consist of exploration without enemy contact - [[{{NothingIsScarier}} which, in this environment, only makes it worse]].]]
* The Subspace of "Subspace Emissary" in ''[[VideoGame/SuperSmashBros Super Smash Bros. Brawl]]'' is this coupled with AmazingTechnicolorBattlefield. And it only gets weirder when the parts of the regular world that were dragged into the Subspace are assembled into the [[MarathonLevel Great Maze.]]
** In ''Wii U/3DS'', [[spoiler:Master Core itself turns into one of these, named 'Master Fortress'.]]
* ''VideoGame/TheLegendOfSpyro'' has Convexity, a gateway between the main world and the Dark Realms, occupied by the Dark Master. It's the location of the final boss battle, featuring floating platforms and strange whale-like creatures with tentacles.
* ''VideoGame/ElShaddaiAscensionOfTheMetatron'' has the Tower, where the majority of the game takes place. Each floor of the tower is ruled by a fallen angel and is essentially its own pocket universe where that angel and its followers live. Locations range from a burned-out wasteland to a cutesy cartoon-like world of colorful blocks and balloons to a futuristic {{Tron}}-like cityscape (complete with cycle combat!) to an underwater world. There's also the Darkness, a location that corrupts everything that falls into it [[spoiler:and is where the souls of the angels' followers end up instead of Heaven]].
* ''VideoGame/FallenLondon'':
** The Neath from the first game and its spinoff ''VideoGame/SunlessSea''. There is a theory that the giant cavern is the skull of a dead god. It is very difficult to die there because it's downstream of Hell. Finding one's way around it can be ''literally'' maddening. An unnerving number of the places you visit are probably alive. You might accidentally walk into someone else's memories. People there keep tigers as pets, make wine out of mushrooms, and play a boyish game based upon stabbing other people. The islands far beyond London keep swapping places when you aren't looking, making maps useless after enough time. You can become used to much of the Neath, but there are a couple places in it that are... different.
** In Polythreme, inanimate objects come alive. A Clay Man explains, "IN POLYTHREME THE BED I SLEPT ON WAS A SLAVE. THE ROOM WHERE I SLEPT WAS HACKED FROM SCREAMING STONE. THE WATER I DRANK BEGGED ME TO STOP. THEY PAID ME IN COIN THAT PLOTTED MY DOWNFALL. THE MEMORIES ARE TROUBLING. THIS PLACE IS BETTER."
** The Iron Republic is a place of true freedom - not even the tyranny of nature rules there. Everything is in a constant state of flux, and the straightforwards interface becomes deranged ramblings. Writing a report on it will net you something either completely blank or ''explosive'', and the punctuation's practically guaranteed to try to eat you. Gather enough protesters and you can literally protest something into existence, or make it disappear completely. The laws of mathematics change every Thursday, which makes accounting just plain intolerable. And even then, what Thursday is probably also changes constantly. And, since it's in both Fallen London and Sunless Sea, you can even ''buy items for the wrong game''[[labelnote:*]]It's been documented you can buy Supplies and Fuel, vital for Sunless Sea but absolutely useless in Fallen London, for no reason at all beyond the fact it's the Iron Republic[[/labelnote]]. The only law is, there is no law.
** The Cave of the Nadir. Lost to history for quite a while, a pain to find even with an enormous archaeological team, pretty much ''everyone'' has an interest in knowing its location, and once there you might wish you never found it. Why? [[spoiler:The entire cave is Irrigo, a mysterious and horribly dangerous color resembling a deep, intense violet. It soaks into you, and stays with you like an insidious radiation, eating away at your memories, your thoughts, and eventually your mind itself. The cavern is full of individuals of all kinds and species that have completely lost themselves, and are completely unable to remember anything, or think clearly. Prolonged exposure will cause your skull to ''grow bone over your eye sockets'' in a futile effort to stop it. Forgotten memories bounce around the place with no rhyme or reason, and make you remember things you never experienced before departing just as quickly as they came. And if you forget your own name, [[AndIMustScream you can never, ever leave]]. And there are theories this color is what makes the entire Neath an Eldritch Location in itself]].
** Irem was strange. Irem is strange. Irem will be strange. It's basically what happens when you sail straight to the edge of dreams (coming in from an actual physical place), and found a city in the border. Or what happens when you will do that in the future. Either way, it hasn't been founded yet, but you can visit it, and have a jolly good time over there, and come back with not much trouble. You'll have been there when the time comes. And yes, in case you haven't noticed TimeTravelTenseTrouble is a ''huge problem'' when writing port reports.
** The Twin Castles of Frostfound, up North where the ice and cold reign. These two are very, very deeply linked to the Gods of the Zee, and entering them will piss them off, with no seeming reason given. Entering any of the two will start eating away at your mind, particularly your memories and stories, until there's nothing left of you. And a little less unnervingly (which shows by what standards we're playing by now), space inside the castles just doesn't seem to work right. Bringing a certain crewmate inside will lead to you spotting him disappearing through the wall never to be seen again, for example. And if you want to enter, there's no doors. You have to close your eyes and go forward, and you'll just... be there, in a series of chambers that will eat at your mind and/or possessions.
** Avid Horizon. No matter how you twist and turn in your road, if you travel North for long enough, you will end up here. There is no way to continue further North. It's an enormous, unbreachable gate with an odd rubbery texture, guarded by two statues, all of a deep Gant colour. Gant being what remains when all other colors have been eaten. Everyone, even your fungal cargo, is unnerved when approaching the place. The fake stars above start flickering like they're going out as you approach. And the gate isn't a thing. It's a Law. And sometimes, when the guardians aren't aware... the law can be breached. [[spoiler:And somehow, ''somehow'', it leads to outer space]].
** Kingeater Castle. Nobody has any idea what the hell is up with the place. People can willingly give up their sanity, and even their past and future. The sense of a great impending mistake pervades the air as you approach. Praying to the most mysterious of the three local deity-like beings can occasionally send you there for no given reason. Something about the place just conducts you towards the most horrible decisions. And a terrible hunger seems to reign all throughout it. It's quite remarkable that even in a place like the Neath, where the strangest of all things get explanations and are considered normal, this is one place that is still feared and unexplained.
** And in this literal ocean of madness, there manages to be an inversion to this trope in the form of Aestival. A simple, quiet island of sand and rocks and some vegetation. Nothing more to it, because the Sun shines from outside and into it through a hole in the Neath, and the Neath's local variety of weirdness tends to react [[WeakenedByTheLight very badly]] to it. Shame this also includes people who've lived in the Neath for any significant length of time.
** The zeefloor proves itself just as strange with the ''Zubmariner'' expansion. It rearranges itself ''much'' more often than the surface does, the wildlife goes from merely being more awful than surface versions of the same to making absolutely no biological sense, it occasionally grows bubbles of impossible colors with terrifying effects, random clouds of pure darkness can appear from out of nowhere, it occasionally has a gigantic eye that can be sailed into and contains MindScrew incarnate and the shadow is so intense ''[[EldritchAbomination things]]'' can slither out of it every now and then. And then there's the various Abysses, where [[HumanoidAbomination the Lady in Black]] can be found... Ironically enough, the underwater ''ports'' are all relatively normal in comparison to some of the above. The strangest of them by our standards ([[ElephantGraveyard the Gant Pole]], [[CyberneticsEatYourSoul Anthe]], [[WombLevel Nook]] and [[StarfishAlien Aigul]]) are just par for the course by the time you can submerge, and the strangest for the Neathers (Hideaway, a city atop a GiantEnemyCrab) is outright ''normal''.
** Not only does the Neath contain several of these locations, it's the only place where the usual pathways to yet another, ''much'' bigger Eldritch Location will work as such. The place is Parabola, and the pathways are dreams, Prisoner's Honey, and mirrors. Yes, normal mirrors, and any sort of dream you have will take you to Parabola for a brief time. And people that are going entirely insane and having the most horrible nightmares have been known to just... ''stumble'' into the place by accident with no way out for a long time. Its outer borders, the Mirror-Marches, look like an endless jungle with oddly familiar ruins of the previous four cities, Earthen fauna that acts a little too strangely, and with framed mirrors partially embedded into the ground everywhere. These mirrors are the other side of regular mirrors back in the Neath, and you can peer back into reality through them. The laws of reality are just a bit more tenuous here, and you can pull off certain tricks that even the Neath's lax rules don't allow. It's also stated that deeper into Parabola, things get much stranger, including things like a marsh where the light of every snuffed candle comes alive. The rulers here are known as the Fingerkings, [[spoiler:who are tiny, flying snakes with RealityWarper powers within Parabola and who like to [[GrandTheftMe snatch up dreamers' bodies to check out reality]], and also make deals with people to give them strange powers, being particularly fond of stage magicians]]. Cats love the place, however (though they despise the Fingerkings), probably because they get to decide their forms in here and [[PantheraAwesome enjoy being big, badass cats]].
* The Otherworld, the final location and lair to the FinalBoss from ''VideoGame/{{Miitopia}}''. It is a strange, allegedly cursed place in which, according to [[spoiler:the Ex-Dark Lord]], no regular human could survive. It is a psychedelic and eerie place populated by sentient rocks and aliens, with weird undulating lines dancing in front of a deep purple void and the floor is in blurry colors with occastional star patterns racing through it. Its most distinctive feature though is the countless luminescent stolen Mii facial features seen floating in the background and the occasional purple bubble floating in the foreground. It is also unclear whever the Otherworld is set in space or in another dimension.
* The '''entire''' world of ''VideoGame/{{Limbo}}''. It's dark (as in pitch-black save for the rare spot of light), silent, and [[EverythingTryingToKillYou literally everything is after your blood]]. [[PuppeteerParasite Or your brains]].
* ''VideoGame/{{STALKER}}'' is set in the Zone of Exclusion surrounding the Chernobyl Nuclear Power Plant after its infamous meltdown. Referred to simply as "the Zone", said location has become a place when only the most heavily-armed and foolhardy ever set foot due to massive amounts of both leftover nuclear radiation and ''[[RealityIsOutToLunch incredibly weird shit]]''. Aside from all the "normal" stuff - wild dogs, mutants, bandits, military troops, radiation pockets, and hostile factions - you have the anomalies: getting too close to what looks like a patch of empty air can [[LudicrousGibs reduce you to bloody chunks]]; that lightning-looking ball hovering over the ground can electrocute you; that patch of air that looks like it's shimmering in the sun can spit out a jet of fire that will burn you alive instantly if you're not protected enough. And those are just the ''obvious'' hazards. At one point, you encounter an endlessly looping room. At another, [[AlienGeometries you find a lake that is also a hill, and that lake flows several yards into the air]]. If you're caught improperly sheltered during a [[RedSkyTakeWarning blowout]], you'll find it's even more bizarre and even more dangerous than ever. [[YourHeadAsplode Briefly.]] [[BilingualBonus If you understand Russian]], the other stalkers have some... ''interesting'' stories to tell by the campfires, too. And lastly, the artifacts, your main source of income and stat boosts for the games, are are formed by the previously mentioned anomalies, so they're found exclusively around these areas.
* ''Franchise/MortalKombat'':
** The Netherrealm, which is home to the demonic Oni and is generally about the most depressing place you can be. Of course, it is the MK universe's equivalent of Hell.
** There's also the Chaosrealm, where, as the name would imply, nothing makes any sense whatsoever. The prevailing theme of the realm and all of its inhabitants is that they adamantly refuse to conform to any set of rules (especially the laws of physics). It is even implied at one point in [[VideoGame/MortalKombatDeception Deception's]] Konquest mode that natives of other realms who stay there long enough will inevitably be driven insane as their mind struggles to make sense of the place.
* ''VideoGame/BlazBlue'':
** The Boundary can be classified as this - a nexus for all timelines, and so chock-full of nastiness and {{mindrape}} that mere ''entry'' can destroy you in some shape or form. Precisely eight beings are known to have traveled through the Boundary, either for TimeTravel or some other reason.
** Ragna the Bloodedge: Involuntarily dumped into the Cauldron at Kagutsuchi by Nu-13. [[spoiler:Not much is known happens to him at this point, though it's assumed that his soul was either ripped apart by the Boundary or became a new Black Beast, smelted in the cauldron and later released. He later does it again in Chrono Phantasma, this time in a controlled scenario with Rachel's assistance, and emerges 100 years in the past and eventually becomes Bloodedge.]]
** Nu-13: Tosses herself into the Cauldron at Kagutsuchi together with Ragna after impaling them both with her Calamity Sword. [[spoiler:It's never revealed what happens to her at this point, though it's assumed that she either was torn apart by the Boundary or was smelted into a new Black Beast before the ResetButton was pushed.]]
** Lotte Carmine: Willfully entered the Boundary ForScience [[GoMadFromTheRevelation Goes insane due to exposure to forbidden knowledge]], loses his body soon thereafter and becomes Arakune.
** Litchi Faye-Ling: Momentarily enters the Boundary to gain the knowledge and power to save Lotte above. Gains telekinesis and the ability to tap into the power of the Boundrary, but is slowly developing memory loss symptoms and is in danger of turning into another Arakune.
** Hakumen[[spoiler:/Jin Kisaragi]]: [[spoiler:Jumps into the Cauldron after Ragna and Nu-13. Goes back 100 years in time, succumbs to injuries sustained prior to dive, but otherwise emerges unharmed - all mental damages relate to transfer to the Susano'o Unit shortly thereafter. Also engages Yuuki Terumi in a duel as a diversion so Jubei and Claudius Alucard can banish Terumi to the Boundary, [[HeroicSacrifice in the process sealing away Hakumen as well]]. Emerges 90 years later at 20% power, but has remained physically and mentally sound due to sheer force of will.]]
** Yuuki Terumi: [[spoiler:Banished to the Boundary during engagement with Hakumen. Lost the artificial body he was possessing at the time. Effects on mental state indeterminate due to prior batshit insanity.]]
** Relius Clover: [[spoiler:Enters the Cauldron for reasons unknown. Emerges 80 years later, physically unharmed; memories are jumbled during transfer, but are quickly reset to pre-jump state.]]
** Makoto Nanaya: [[spoiler:Loses her consciousness in proximity to Cauldron at Ibukido due to Prime Field Device activity and emerges in the ''Wheel of Fortune'' timeline. Travels back to ''Continuum Shift'' timeline with aid of Rachel Alucard. Zero physical and mental degradation in both transfers.]]
* ''[=BlazBlue's=]'' predecessor, ''VideoGame/GuiltyGear'', has the Backyard, a parallel world teeming with information which also serves as the source of magical energy for the world. Entry for most people into the Backyard is dangerous: without "tuning" to the Backyard's frequency, they risk being destroyed by the information inside it.
* Historia in ''VideoGame/RadiantHistoria'', [[spoiler:as well as Granorg's Royal Hall. Its final boss Apocrypha also looks something like this, albeit shrunk.]]
* ''Franchise/TheElderScrolls'':
** The series' universe itself. Starting with the AlienSky itself, the sun and stars are not typical balls of burning gas but holes punctured in reality by escaping spirits during the creation of Mundus, the mortal plane, and magic flows through them into Mundus which is visible in the night sky as nebulae. The [[WeirdMoon two moons]] of Nirn (the planet within Mundus that all of the action to date in the series' has taken place on) are said to be the rotting and sundered "flesh divinity" of Lorkhan (also known by [[IHaveManyNames other names]]), the [[TheMaker creator god]] of Mundus who was [[GodIsDead "killed"]] by the other spirits who aided in creation, now known as the [[OurGodsAreDifferent Aedra]]. The planets visible from Nirn are not typical planets, but are the planes and "flesh divinity" of the eight most significant of these Aedra. It is said that these forms all appear as they do because [[YouCannotGraspTheTrueForm it is the only way for a mortal's mind to comprehend it]]. That said, this information primarily comes from subjective in-universe sources who often conflict with each other, as the series is well-known for its [[UnreliableCanon intentionally contradictory lore]]. Just like many [[ScienceMarchesOn discredited beliefs]] in [[{{RealLife}} the real world]], the "true nature" of the TES universe could very much be as "normal"/conventional as our real universe is, or it could be something else entirely.
** The various planes of Oblivion, the "infinite void" surrounding Mundus, may be the [[GeniusLoci physical forms]] of the [[OurGodsAreDifferent Daedric Princes]] they are associated with. They are not bound to any of the laws of nature and physics that bind Mundus, and are subject to change on the whim of the associated Prince. Even [[YearInsideHourOutside time does not flow normally]] within Oblivion, though the exact details often vary. For example, when [[TheGoodKing Emperor Uriel Septim VII]] was imprisoned there by his EvilChancellor CourtMage Jagar Tharn for 10 Nirn years, he did not age a day. For specific details on the planes of the Daedric Princes, see the series' [[Characters/TheElderScrollsDaedra "Daedra" Characters]] sub-page.
** The island of Artaeum combines this with {{Bizarrchitecture}} and AlienGeometries. Artaeum is the home of the [[TheOrder Psijic Order]], a powerful MagicalSociety and the oldest monastic order in Tamriel. Artaeum shifts continuously either at random or by decree of the Psijiic Council. It can also be made to disappear ''entirely'' from Mundus.
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]''
*** In the ''Dawnguard'' DLC, you visit the [[SpiritWorld Soul Cairn]], a realm of Oblivion created by the Ideal Masters, a group of immortal beings who [[WasOnceAMan were once powerful mortal sorcerers]]. The Ideal Masters have a HorrorHunger for souls, especially the "Black" souls of sapient beings, and they [[YourSoulIsMine are always seeking to claim more]]. The Ideal Masters prefer [[EnergyBeing forms of pure energy]], as they find physical forms to be "too limiting". However, they will take the form of giant crystalline soul gems within the Soul Cairn, and can drain the souls of mortals who venture too close. Other Soul Cairn inhabitants include the captured souls [[FateWorseThanDeath doomed to spend eternity there]], grotesque undead monstrosities that randomly appear from the ground, and a {{Dracolich}} [[NinjaPirateZombieRobot zombie dragon necromancer]].
*** In the ''Dragonborn'' DLC, you visit Apocrypha, the realm of Hermaeus Mora, the Daedric Prince of Knowledge (with a particular specialty in [[TheseAreThingsManWasNotMeantToKnow Things Man Was Not Meant To Know]]. Reading one of Mora's "[[TomeOfEldritchLore Black Books]]" causes you to be ensnared by a tentacle that formed from letters which float off the pages, pulling you inside. The realm itself is a place Cthulhu would find comfy. All the walls are made of books, the water is slime and sprouts tentacles to attack you if you get too close, there are invisible monsters roaming the halls and sea mutants in the slime, certain areas have darkness that can kill you, and the architecture isn't necessarily static. On a more meta note, it also does not help that the area is notoriously [[GameBreakingBug glitchy]] so that when the when the layout of certain tunnels shifts, the Dovahkiin tends to clip and fall through the floors and walls into the deadly slime. But if you brave these horrors, the Black Books will grant you amazing powers.
* Astral Chaos in the ''VideoGame/SoulSeries'' is a timeless alternate dimension from which the Soul Swords originate, and is filled with lost souls and an EldritchAbomination or two.
* The Labyrinth of Deceit in ''VideoGame/KidIcarusUprising'' is a maze full of fake walls, holographic asteroid belts, gravity inversion switches, and disappearing paths. And even when you're not caught up in an illusion, the walls, ceilings, and floors are decorated... odd. And did we mention it's found inside a [[OurWormholesAreDifferent Space Rift]]?
** [[spoiler: And then Chapter 21 has the Chaos Vortex, which is basically the Labyrinth of Deceit taken UpToEleven. It contains replicas of ''every'' enemy from all four factions, [[LivingShadow living shadows]] that attack, eye-shaped portals that spring up out of nowhere, pieces of buildings that randomly move about, floating islands. It's just weird.]]
* ''VideoGame/Kirby64TheCrystalShards'' has [[spoiler:Dark Star, a planet made of [[EldritchAbomination Dark Matter]] and the {{Very Definitely Final Dungeon}}. Not much time is spent inside of it, but its red skies, ribbons of darkness and crystalline hexagonal tiles give it this vibe and make it significantly more alien than any of the planets visited in the game.]]
* Hang Castle in ''VideoGame/SonicHeroes'', but especially its interior, Mystic Mansion. In the daytime, it's a normal abandoned castle, albeit an exceptionally large one. At night, the exteriors seemingly extend endlessly in all directions, and gravity doesn't always point downwards. Once inside, rooms suddenly change topography (sometimes when Sonic and the others are in it), things pop in and out from impossible places, there seems to be a physical upside-down version of the mansion underneath the normal one, dumbwaiter tracks twist and contort while zooming off at high speeds, Eggman's robots pop up out of thin air (presumably intentionally), and what is supposed to be a well is full of weird vaguely water-like texture in all directions with a few small brick platforms suspended in it.
* The ''Franchise/TombRaider'' series has had a few of these, but two that stand out are the Atlantean Temple in the first game and ''[[VideoGame/TombRaider Anniversary]]'', and ''Tomb Raider II'''s Floating Islands level. In the first example, the deeper into the complex you go, the more organic the architecture gets, until the walls are made of pulsing muscles. The Floating Islands are...well, ExactlyWhatItSaysOnTheTin, a series of floating islands inside of a Chinese tomb.
* ''VideoGame/TheSecretWorld'' features several:
** One of the more benevolent examples arrives in the form of Agartha, a hollow Earth filled with branching trees, giant robotic caretakers, and a lot of bees, perpetually lit by sourceless golden light. It's actually a divine biocomputer and font of anima (i.e. magic), and it also functions as a weird PortalNetwork usable only by those touched by Agartha's bees (it "precipitates a messy discord" in the flesh of the uninitiated).
** On the other side of the metaphysical spectrum, places severely impacted by [[TheCorruption the Filth]] begin to corrode reality, opening starry portals to distant and lifeless space. One of the worst areas is "The Breach," an excavation site in Transylvania that's been converted into a massive wellspring of the Filth by the Orochi Group and the Vampire Army. We see another such location during the prologue, where Ground Zero for the Filth bomb detonated in the Tokyo subway has all but completely lost contact with reality. For the player, such locations are also a doorway to...
** ...the Dreaming Prison. A semi-metaphysical landscape of glittering black-sanded beaches under a midnight sky with a broken moon and blocks of white ice drifting overhead, dotted with massive cuboid shapes of an unknown material called the Gaia Engines. These things ''literally'' keep the world running, though Freddy Beaumont implies they can be used for "[[TakeOverTheWorld other things]]." For good measure, it's also a prison for the monstrous beings that produce the Filth, kept dormant by the Engines, and it's up to you to either reinforce the prison or help the inmates escape.
** The City of the Sun God. Built by Pharaoh Akhenaten in Egypt as an act of devotion to the Aten, it's on another Filth wellspring, and the results have turned into into a gathering point for just about any malevolent force in the area. The ''portals to {{Hell}}'' open in two corners of the valley don't help, but they're ''not the most eldritch things in the area''. The centerpiece of the alley is the Black Pyramid, Akehnaten's resting place. Thanks to a combination of arcane magic and the Filth's reality-warping influence, massive chambers and hallways fit inside despite clearly being too large for the structure. One of these rooms is a literally bottomless pit - above which the dormant [[HumanoidAbomination Akhenaten]] slumbers.
** In the update "The Vanishing of Tyler Freeborn", the Mist surrounding Solomon Island is revealed to be hiding one of these. [[spoiler:Specifically, the Red Sargassum Dream, a twisted recreation of the town of Kingsmouth under a perpetual midnight sky, inhabited only by Filth-infected versions of the locals.]]
** The Hell Dimensions are a FireAndBrimstoneHell that's almost completely starved of anima. The creatures inhabiting the place, identified in human folklore as demons, frequently try to steal anima from Earth, occasionally through [[HellOnEarth demonic invasions]] but more commonly by tempting humans into [[DealWithTheDevil signing over their souls]]. The environment in Hell is toxic to humans and capable of turning blood to metal, such that only those touched by Agartha's bees can survive down there. Theodore Wicker, a human mage interested in Hell, had to perform heavy magical alterations on his body (including tearing his heart out) in order to adapt to Hell's conditions, such that life on Earth became uncomfortable for him; he wound up leading a rebellion against [[{{Satan}} Eblis]].
* ''VideoGame/StarWarsTheOldRepublic'' has the Voss [[IDontLikeTheSoundOfThatPlace Nightmare Lands]], filled with barren soil, twisted trees, mutated wildlife, and a pervasive corruption field that reduces the weak of mind (read: everyone but the player characters) into violent psychopaths or blubbering vegetables. As an added bonus, there are no less than 5 quests available to deal with {{Eldritch Abomination}}s.
* The ''VideoGame/{{Thief}}'' series contains a few of these, notably Constantine's mansion, the Old Quarter and the Lost City in ''[[VideoGame/ThiefTheDarkProject The Dark Project]]'', and Shalebridge Cradle in ''[[VideoGame/ThiefDeadlyShadows Deadly Shadows]]''.
* ''Franchise/SuperMarioBros'':
** The level Matter Splatter Galaxy in ''VideoGame/SuperMarioGalaxy'', due to the unusual physics of the solid objects and grounds that only appear when a particular field of matter gets close enough. The green-colored background of the level is even more surreal.
** Compared to the rest of the DreamLand, Dream's Deep from ''VideoGame/MarioAndLuigiDreamTeam'' counts. While most of the other dream locations are more-or-less surreal versions of the area Luigi sleeps in, this place is implied to take on the appearance of the sleeper's subconcious. In this case, it's a large purple space with floating neon Luigi faces and holograms, with quotes representing his thoughts flying around. [[AlienGeometries There are places where going off on one end of the screen takes you to another location of another, and even how this works doesn't have to be constant. On the first visit, (the dreamed version of) Luigi goes missing until the boss fight, yet if you leave before said boss, he's back and claims that he was right behind Mario the entire time.]] And finally, the only "natural" inhabitants are Dark Blocks, [[SpritePolygonMix which are animated in actual 3D]] in contrast to game's "pseudo [=3D=]" sprites seen in the normal battle mode.
** The whole Violet Sector of ''VideoGame/PaperMarioColorSplash''. We have a sentient ocean, a whirlpool that never goes away, an area of the ocean that is pitch black in broad daylight, and smoke coming from out of nowhere. Except for the first thing, everything is a result of things going on in the Alternate World.
* In ''VideoGame/FarCry3'', it's implied that there is something subtly but fundamentally ''wrong'' with the Rook Islands. The extremely hostile animal life, the gradual madness that consumes anyone who goes into the jungle, the strange and mystical relics, the drugs giving accurate prophetic visions, [[spoiler: the ink demon]], and so on. It's not obvious, but the islands are ''doing things'' to the people who spend time there. However, due to the game's MaybeMagicMaybeMundane nature, it's left unanswered whether there is actually something wrong with the place, or if it's just the player character [[{{SanitySlippage}} losing his mind to drugs and trauma]].
* ''Videogame/KerbalSpaceProgram'' has Jool, which at first just looks like a green Jupiter. And then you get anywhere remotely close to it, and physics start getting more than a little odd, and only get nastier as your ship gets close, culminating in it spontaneously exploding while you're still several hundred miles from the surface. And then your poor astronauts fall in, and [[WreakingHavok their limbs]] [[BodyHorror flail in impossible ways]] before they simply die. And that's the ''best'' case scenario; there's the occasional tale of ships that survive entry getting flung out of the galaxy at FTL speeds. Of course, it's not actually meant to be that way - it's just glitchy as hell - but the fans have latched on to the first interpretation to match with a certain GoodBadBug being blamed on an EldritchAbomination. Funnily enough, it's this exact same weirdness that makes it completely immune to any and all attempts to (further) glitch it out, and not from lack of trying. And since many of those glitches tend to destroy entire planets...
* ''VideoGame/{{Dishonored}}'' has the aptly named Void, which consists of a series of islands floating in space, depicting fragments of real world buildings and characters frozen in time. It's the home of [[HumanoidAbomination the Outsider]], who will quite effortlessly and arbitrarily drag people there to mess with them or grant them magical powers or both, and it seems to bend to his whims.
* You've got your Shadow Lairs in ''Videogame/SpiralKnights'', but after the boss(es) are defeated, your team is whisked away to a frighteningly empty monochrome (especially compared to the colorful gameworld) tunnel called the Unknown Passage. Some really creepy ambience plays in the background as you prepare for a wave of enemies, and when they arrive, you'll fight TheSwarm.
* The [[OrphanageOfFear Edgewood Home for Lost Children]] in ''VideoGame/OurDarkerPurpose''. Inanimate objects come to often-malevolent life, the architecture shifts unpredictably, and the plants are twisted if not actively vicious. It's hinted that the lands outside the gate are ''even worse''.
* The ''VideoGame/MetroidPrimeTrilogy'' features a few planets that are more than a little twisted because of [[TheCorruption Phazon]] exposure.
** In ''VideoGame/MetroidPrime2Echoes'', Aether was split into two when it got hit by a Phazon meteor (which, in ''VideoGame/MetroidPrime3Corruption'', is revealed to be a Leviathan from planet Phaaze): the light world had some catastrophic global changes, such as plains becoming barren or a woodland jungle flooding but the serious issue was the creation of [[DarkWorld Dark Aether]] which has an atmosphere so toxic it kills any non native in seconds (eating through almost any sheilding), truly sinister landscapes and the locals are always chaotic evil and really don't like light.
** Phaaze, the Phazon planet, [[spoiler: by virtue of being a sentient being that is trying to spread and corrupt other planets]]. It also has some very organic looking natural structures. Lore surrounding the planet suggests that it's an EldritchAbomination existing in a higher dimension, with the planet merely being its form in our Universe. Phaaze is the source of all Phazon, which seems connected no matter how far apart its fragments are. Leviathans are birthed inside its crust, and Phazon versions of the Ing from the previous game appear as common enemies.
* ''{{VideoGame/Rift}}'' features the Planes of Water and Death. The first of these 2 Planes the Plane of Death appeared in the raid: Endless Eclipse and was not only a combination of bones and flesh yet most bizzarely the sky has an sun in an eclipse surrounded by Eldritch symbols.
** The Plane of Water is going to make it's debut in an upcoming expansion and it's first zone Goboro Reef is a sea with spaces of Water carved out of the zone due to the zone's creator waking up(the Plane of Water is actually a DreamLand) leaving walls of water rippling vertically around those waterless spaces.
** The Plane of Water's second zone Draumheim is a city with an ocean suspended over it(due to the inside of the city being effected by the aforementioned water being carved out of the Plane of Water) filled with every creature from everyone's dreams with the southern portion being a desert containing a forest and a bigger and nastier copy of Port Scion ruled by the Lord of Nightmares himself.
** The Plane of Water's third zone Tarkin Glacier is less of an EldritchLocation than the other two due to being a SlippySlideyIceWorld with the mountain at the end being filled with minature Air rifts with it's peaks being floating rocks which are the only Eldritch things about the zone despite the developers' claims of a heavy Lovecraftian influence.
* The ''VideoGame/DarkSouls'' franchise has a number of these:
** The Abyss could practically have a whole entry to itself:
*** The Abyss in New Londo. It's black. And that's pretty much it. No light. No landscape. No horizon. No ground. Just black in every direction, going on forever. You can only survive in the place by wearing a particular magic ring; if you don't, you just fall. Forever. [[spoiler:It was born out of concentrated human essence. That's right, apparently the source of this empty nothingness is ''humanity itself''.]]
*** The ''Artorias of the Abyss'' DLC takes you back to the Abyss, which is represented as an utterly lightless cavern filled with bizarre pitch-black ghosts that look like concentrated Humanity. The worst part is that the Abyss is clearly spreading outward, as strange blue-black ichor covers the surrounding landscape, getting more prevalent the closer to the Abyss one gets.
*** The Abyss is back in ''Dark Souls II'', now called the Dark Chasm of Old, where it can only be entered as a spirit, and contains spirits of other warriors endlessly wandering its cave-like halls killing anything they see, alongside these weird tree-sorcerer things. And the boss of the area is a creepy angelic being called the Darklurker, which absolutely nothing is known about.
** The Crystal Cavern. It's a huge cave that is home to bizarre monsters and invisible platforms. The sheer wrongness of the place seems to reflect the madness of the being who made the cave his sanctuary, Seath the Scaleless.
** Ash Lake. It's a small remnant of what the world looked like before the Fire and before the Lords defeated the Everlasting Dragons. It's a seemingly endless expanse of grey water, with gigantic, utterly massive trees extending up beyond the clouds that blanket the sky. All you find down here are a scarce few enemies, and even the small beach you explore is huge compared to most other areas in the game. The sheer scale, uniformity, and silence of the place, combined with the mournful music, just creates a feeling of emptiness.
** The Old Chaos in ''Crown of the Ivory King''. Beneath the frozen land of Eleum Loyce lies a giant inferno with tree roots branching all over the place yet not burning, and the battle takes place on an inexplicably floating stone platform far above an endless sea of flame, with doorways that contain fiery portals that spawn corrupted knights. [[spoiler:The roots and branches are meant to evoke Lost Izalith from the first game, where the Bed of Chaos was fought. It seems to be hinted that the Old Chaos is the Bed in a new form.]]
** The Untended Graves in the third game are a near-exact replica of [[spoiler:the tutorial area and Firelink Shrine... except crawling with much more powerful Undead, Black Knights, and covered in pitch darkness. One character's dialogue implies that the place is a look into an AlternateUniverse where the Fire has finally died and the Age of Dark has come. Since Firelink Shrine can only be accessed via bonfire-warping, while the Untended Graves can be reached on foot from the rest of the game, this has disturbing implications.]]
** The entire realm of Lothric is implied to be one in ''Dark Souls III'', as it's an amalgamation of different lands once ruled over by their respective Lords of Cinder, summoned across time. Even more so in the Kiln of the First Flame, which seems to be made up of an illogical jumble of buildings and architecture haphazardly piled on top of one another across an endless plain of ash and half-melted spires of rock.
* [[OurVampiresAreDifferent The Forest of Einnashe]] in ''Franchise/{{Nasuverse}}'', first mentioned in ''{{VisualNovel/Tsukihime}}''. It's a forest that acts like a vampire, in that it eats every person and animal that comes upon it. And yes, it can move and hunt ''cities'' on its own. Good thing it's only shown itself every 50 years.
* ''Franchise/{{Nasuverse}}'' also gives us [[MentalWorld Reality Marbles]]. It is a high-level magical barrier that forced reality around oneself to ''obey'' your vision of the world. As a result, it turns reality within one's proximity into one's own mental landscape, allowing them to use their ultimate techniques. These are traditionally possessed by [[EldritchAbomination Ultimate Ones]] and high-level spirits.
* The Red Night in ''VisualNovel/ElevenEyes''.
* ''VideoGame/{{Diablo}}'''s Tristram Cathedral definitely qualifies. It begins with ''mere'' demon infested crypts, and only gets worse from there. It's revealed that [[RealityWarper Diablo's mere presence]] is warping the lower floors into Hell.
* ''VideoGame/FlightRising'' has the Starfall Isles, the homeland of the Arcane Flight. The ''first sentence'' of its encyclopedia page describes it as "the twisted, broken islands of the Arcanist and his scholars" and it only gets creepier from there. Every part of the region, including the wildlife, is being mutated by the magical energy flowing through the area, from the mountains which have curved inwards, the shoreline that is now a glowing forest, and the formerly-low island which keeps growing higher. There's also the [[ExtraEyes eight-eyed]] hummingbirds, levitating pill bugs, and owlets that turn pink when they hatch at the Observatory...
* ''VisualNovel/{{Demonbane}}'':
** The first game's final battle took place in a succession of these taken from the ''Literature/CthulhuMythos'' itself, as the sheer power being exchanged between Demonbane and Liber Legis causes "dimensional quakes" that randomly throw them all over time and space. They visit, in order: the chaotic darkness of the Void Beyond, the Great Library of Celeano, a ruined Yaddith of the far future, a living asteroid field, Prehistoric Earth, the Darkness of N'Kai, and in a couple of routes finally end up on the dead world of Yith.
** The Shining Trapezohedron is ''itself'' an EldritchLocation, and sealed within it are [[spoiler:all of the evil gods that Demonbane could not kill, trapped within one universe and screaming to get out. Slashing something with the Trapezohedron sends it to that universe... where that thing will be at the [[FateWorseThanDeath mercy of all those extremely angry, immortal, evil beings.]]]]
** The sequel's villain turns Arkham City into an EldritchLocation, as it becomes a patchwork of different time periods, urban city and wilderness melting into each other, buildings that are upside-down and right-side up and everything in between, and time moves faster, slower, backwards, or not at all in various places.
* VideoGame/TheEvilWithin: The entire setting. What starts out as an odyssey into a zombie-infested county gives way to SchizoTech, frequently shifting landscapes, and a slew of {{Eldritch Abomination}}s. It's revealed two-thirds into the story that [[spoiler:Sebastian is inside a hive-mind controlled by an extremely deranged sociopath. Which explains the monsters and why he's able to upgrade himself and his weapons by injecting himself with brain fluid - the monsters are the manifested nightmares of the various minds inside a simulation, and injecting himself with the defeated brains represents taking control of the simulation]].
* ''Videogame/{{Bloodborne}}'': It's never quite clear where the normal places end and the stranger places begin, considering some of the weird stuff your character starts to find once you start acquiring Insight, but a few places stand out:
** Byrgenwerth College's Lecture Building, and the college in general, which [[spoiler:seems to have been dragged off screaming into the Nightmare realm, and while it still more or less looks normal, it's warped inhabitants (which include its old students turned into slime monstrosities) will quickly tell you otherwise. Oh, and it somehow hid an entire, endless lake of shimmering white in the moon's reflection in a small pool. And killing the entity you find there will quickly drag the whole town into madness]].
** Yahar'Gul, [[spoiler:a town within a town. Somehow, the entities in charge of the whole MindScrew managed to hide a large, nightmarish citadel that resembles an earthbound R'lyeh, within the small town of Yarnham. Most specifically, in one of the cathedrals]].
** And, of course, the Nightmare Frontier, [[spoiler:the Great Ones' actual realm, crawling with stuff that will destroy your sanity in seconds, and housing the nightmares of several important players in the whole scheme, in particular one that acts as a freaking EldritchAbomination ''nursery'']].
** In a way, the Hunter's Dream and possibly [[spoiler:''every single thing after the blood transfusion at the start of the game'']] counts. It's simultaneously AllJustADream and a real, actual place you can go to. And sometimes, for extra MindScrew, you can access the dream part and the real part separately, leading to oddities such as finding the long-dead corpses of people you met minutes ago. And while they seemingly don't affect each other, as the game goes, you learn that it most definitely ''does''.
** There's also the Nightmare of Mensis, what is essentially a giant castle in the middle of a mental dreamscape that houses multiple EldritchAbomination s and appears to be the headquarters of the School of Mensis, a faction of the game's CorruptChurch that wishes to contact the ''other'' {{Eldritch Abomination}}s.
** ''The Old Hunters'' introduces the Hunter's Nightmare, a twisted version of Yharnam (which is already twisted as it is) populated by AxCrazy Hunters who have been damned to this realm. There's so much carnage to be found, that a river of blood cuts through the city from thousands of mutilated corpses that turn out to be NotQuiteDead once you come close to them. And at the end, after traveling through the clocktower of a BedlamHouse, you come to the source of it all: [[spoiler:[[Literature/TheShadowOverInnsmouth a small fishing hamlet]] populated by FishPeople that's been dragged into a nightmare dreamt by the unholy spawn of a dead Great One.]]
* ''VideoGame/TheBindingOfIsaac'':
** A couple of late-game stages could count, but none, more than the stage accessed after killing Isaac's Mom: [[WombLevel The Womb]]. Despite the title giving you an idea of where you are, it's best not to think about it too much beyond that, as it's accessed through a fleshy hole in the floor after beating Mom, is a giant labyrinth of enemy-filled rooms (including Mom's sentient, severed hands in ''[[UpdatedRerelease Rebirth]]'',) and the final stage boss is Mom's ''heart''. Not to mention that there's a literally doorway to ''Hell'' (well, Sheol, but still) in there. And then there's the Scarred Womb in ''Afterbirth'', a variation of the previous dungeon that looks like [[{{Gorn}} someone took a chainsaw to the inside.]]
** The "I AM ERROR Room," a deeply-hidden area that can only be reached by through either random teleportation or, as of ''Afterbirth'', causing a paradox[[labelnote:As in...]]Using a Blank Card (an activated item that replicates the card held by the player) on a ? Card (a card that replicates the activated item held by the player) or using Teleport 2.0 (teleports to the next unexplored room) after exploring every possible room in the map[[/labelnote]]. It has a glitchy floor along a black void, an equally-glitchy shopkeeper with a word balloon reading "I AM ERROR," a direct way to the next floor, and a number of rather random possible items, pickups, or other objects. It cannot be escaped by anything other than teleportation and little to no real in-story reason for its existence.
** The VeryDefinitelyFinalDungeon in ''Afterbirth +'': the Void. The entrance appears at random after major boss fights (always after one particular boss), and appears to be a twisted black portal similar to those that have been spawning enemies. The floor itself is made up of a random assortment of rooms from all other floors, and occasionally is subject to bursts of static that alter the landscape entirely. It's also the only floor in the game to have multiple boss rooms, as many as ''eight'', and only one of them contains the actual boss. Which one it is is entirely random. [[spoiler:The Void and its boss Delirium are a representation of Isaac's mind breaking down as he suffocates to death. If he dies here, the game over screen refers to dying "In some dying memory".]]
* The eponymous dungeons from the ''VideoGame/PokemonMysteryDungeon'' series are explained in-story as this. In ''[[VideoGame/PokemonMysteryDungeonExplorers Explorers]]'', they're said to be the result of temporal and spatial distortions.
* ''VideoGame/MinecraftStoryMode'': The Farlands. Unlike Minecraft, where it was simply a glitch, here it's basically the literal edge of the world and an area of chaos incarnate.
* ''VideoGame/{{DownWell}}'': The Abyss
* ''VideoGame/CorpseParty'' features Heavenly Host Elementary School. It's a haunted, [[GeniusLoci sentient]], [[AlienGeometries multi-layered]] dimension that consists of just the rundown school (it was originally in the real world, but after a series of murders it was torn down) and a never-ending expanse of trees with ceaseless rainfall. Anyone who is unfortunate to be caught in it can and most likely ''will'' die from either hunger or starvation, vengeful spirits, or any number of creative traps [[ChaosArchitecture the school]] will lure the player into, all if the person doesn't commit suicide. Even worse, a person can succumb to the [[TheCorruption darkening]] the school exerts, become insane and contribute to the problem by killing their fellow members. Let's not forget that anyone who dies in the school not only experiences the pain and agony of their death ''forever'', but is also ''[[RetGone erased]] from existence'' in the real world.
** Made even worse with the reveal of [[spoiler:the GroundhogDayLoop and time travel]]. Just as space and planes of existence are warped in this dimension, so is the concept of [[spoiler:time and parallel timelines. It's told that even if you tried to save someone who died before, they will just [[YouCantFightFate die a far more gruesome death]]. Sachiko has mentioned that Yoshiki has died a few times in other timelines, which leads to [[FridgeHorror the realization]] that ''every possible timeline was exhausted'' and Yui, Morishige, Mayu, and Seiko always ended up dying in the school so it was impossible to ever save them.]]
* The ''VideoGame/TalesSeries'' has had its great shares of bizarre locations over the course of its many games, but one area in ''VideoGame/TalesOfVesperia'' is noteworthy: [[spoiler:the parallel dimension where the Adephagos is imprisoned, a ''planet-sized'' squid that sucks aer dry]].
** There's also Tarqaron, a massive floating city that was converted into a weapon to counter [[spoiler:the Adephagos]]. The inside has warped pathways and structures built in every which way, and the party debates on just "what the hell were the ancients thinking when they built this?"
** ''VideoGame/TalesOfZestiria'' has [[spoiler:Artorius' Throne, the final dungeon]]. It's a sealed section of Glenwood that contains a massive palace suspended over an empty void, with collapsed and broken pathways surrounding it leading in every which way. The sky is blood red and the sun is black, and the entire area is engulfed in malevolence. [[spoiler:Makes sense, since a hellonized Maotelus was sealed in there.]]
* In ''VideoGame/ShadowWarrior2'', the in-game justification for the game's ProceduralGeneration is that Earth's landscape is constantly in flux.
* In the ''VideoGame/AlanWake'' games, Cauldron Lake is home to a RealityWarper EldritchAbomination called the Dark Presence, that desires to enter into our world fully as a MonsterFromBeyondTheVeil. In service of its goal, proximity to the lake grants creative humans the power of RewritingReality, though the beneficiaries of this power, protagonist included, tend to exploit it to defy the Presence's will once they glean its malign nature. Cauldron Lake itself is far more [[BiggerOnTheInside deep and vast]] than it appears, as a deep sea fishing trawler has somehow found a way to its suspiciously oceanic depths.
* Indie horror game ''Kholat'' gives us ''[[https://en.wikipedia.org/wiki/Kholat_Syakhl Kholat Syakhl]]'', a.k.a. the ''"Dead mountain"'', a real-life place in northern Urals, Russia.
* ''Franchise/{{Halo}}'':
** [[SubspaceOrHyperspace Slipstream space]] is a set of eleven non-visible and highly radioactive "nondimensions" that has markedly different laws of physics and "topology" from normal space, with FTL travel requiring you to enter it. It was known for making some people disappear without a trace when it was first put to use, and for the longest time it was nearly impossible for the [[TheFederation UNSC]] to accurately plot courses within it at distances smaller than a planetary system, though the [[ScaryDogmaticAliens Covenant]] and [[ThePrecursors Forerunners]] had already mastered that part. These effects worsen as jumps are made further inside a gravity well.
** Additionally, slipspace travel inherently causes all sorts of chronological and causal paradoxes which the universe then has to "reconcile"; if too much FTL travel is happening at once, than slipspace will automatically slow down or halt all traffic within it until reality has finished reconciling itself, with the strange part being that this "reconciliation" affects events both forwards and ''backwards'' in time. Due to humanity's inferior understanding of this phenomenon, two of their ships traveling through slipspace together to the same place will often either exit slipspace at different times or, if they do exit at the same time, experience time with slipspace differently (to the point where one ship's clock might be an entire week ahead of the other's).
** The dimension encountered in ''Literature/HaloFirstStrike'' when the ship containing the main characters enters slipspace using a [[MacGuffin Forerunner crystal]] takes the weirdness [[UpToEleven a step further]]. Energy Projectiles would randomly teleport or follow random trajectories while kinetic weapons were unaffected, with the crystal itself emitting massive amounts of radiation, causing some... [[TimeyWimeyBall contradictions in the recorded timelines]], and [[ArsonMurderAndJaywalking allowing ships to travel much greater distances across space than usual]].
** According to ''Literature/TheForerunnerSaga'', Forerunners discovered a large variety of strange alternate realms, including one composed solely of photons.
** The Domain appears to be depicted in such a way in ''VideoGame/Halo5Guardians'', though no physics defying effects occurred. This makes sense, given that it was created by [[spoiler:the Precursors, who themselves were {{Eldritch Abomination}}s]].
* The upcoming video game ''VideoGame/LittleNightmares'' takes place in a place only known as the Maw, filled with giant monsters and seems to be a cross between a hotel and a steampunk nightmare.
* The Room in ''VideoGame/{{OFF}}''. The rest of the game is [[WidgetSeries bizarre,]] but internally consistent and stable, [[spoiler:if undergoing some sudden changes after being purified]]. The Room is a small area that the Batter goes through multiple times spread across different "chapters" in reverse chronological order. The place changes in each iteration, there's one section where the camera inverts for no explainable reason (and remains upside-down until after solving a puzzle), a portion where you're taken to a mock-up of the main menu and pick three different "save files," a gigantic NPC that wants to play a game where you tell him numbers that appear in other sections, and it includes a segment that appears like a child's crayon drawings. It's implied that the whole thing is ''some'' sort of flashback from [[spoiler:its guardian, a sickly boy seen briefly after beating the first two bosses]].
* The planet Mira in ''VideoGame/XenobladeChroniclesX'' is an unusual planet which is acknowledged by the Earthlings that crash land on it. It features a lot of different climates in close proximity to each other and is crawling incredibly hostile {{Eldritch Abomination}}s, and those are the normal parts. The weird parts are the how the planet does not appear on any star map, the way it draws different alien species to it and prevents them from leaving, the way it acts as a UniversalTranslator for the aliens, and [[spoiler: how it can keep sentient androids running without a power source.]]
* In both games in the ''{{VideoGame/Fairune}}'', the Secret File, a room based around either a desktop file system, an old RPG or a roguelike populated by unkillable Space Invader-styled bit monsters, is this. [[spoiler: In 1, these seem to bleed into the final dungeon, and in 2, this could count for both Ashen World and it's underground, Sky Land.]]
* In ''VideoGame/MapleStory'', there is Ludibrium. On the surface, it's a toy world BuiltWithLEGO, but as you dive deep into its towers, the LEGO walls grow thin, eventually giving you view of some outer-space vista which shouldn't have been possible. It doesn't help that that deep in the towers, you'll see lots of ghosts.
* ''Videogame/HelloNeighbor'': The Neighbor's house, which becomes even more twisted and nonsensical with every update. As of Alpha 4, making it far enough into the house reveals rooms leading to nowhere, a fully-operating train supported by nothing, winding hallways, and all sorts of additional physics-defying hazards.
* In ''Videogame/Metro2033'' and ''Videogame/MetroLastLight'', the nuclear war that wiped out human civilization on the surface also broke the barrier between heaven, hell, and reality. Throughout the series, there's a number of locations where they all blend together, some of which are benevolent, and others that are antagonist either through malice or [[PleaseDontLeaveMe their own isolated misery]]:
** In ''2033'', you can find the ghost of a ''subway train'' that endlessly moves across the tunnel before being crushed in a tunnel collapse. On the actual wreckage, ghosts sit on their morning commute.
** In ''Last Light'', the passenger plane that crashed into Moscow is haunted, and those that enter the cockpit see the plane's last moments as the disables plane plows into an apartment block being blown apart in nuclear fire.
** In ''Last Light'', there is a tunnel on the surface haunted by the corpses of the untold millions that died. Their ghostly arms try to grab anyone stepping through because they are lonely and afraid.
** The weirdest is The River of Fate in ''Last Light'', a GeniusLoci where the dead can place phone calls, skeletons stare you down as you pass by, oh and you can [[TimeTravel view the past with your buddies]].
* In ''Warframe'' there is the Void, a dimension that can only be accessed through special keys. The area appears as a vast expanse of space and pure energy, with only the occasional abandoned Orokin tower [[spoiler: or the moon]] floating in it's space. It is the source of all energy that the Tenno use and it has close ties to the lost god-like race of the Orokin. Occasionally fissures in space leak void energy and allow the Orokin towers to use their mind controlling power extend their reach. [[spoiler: General Vor was even able to become a pure godlike being of energy with the use of a special void key.]]
* ''VideoGame/{{Sundered}}'' takes place in a series of impossibly vast caverns deep beneath the earth, [[ChaosArchitecture whose layout and architecture change every time the protagonist dies]]. The environments within the caverns start out relatively mundane, but become progressively more bizarre and disturbing the further down you go:
** The Valkyrie Encampment seems fairly normal at first, being a lush, jungle-like region with strange rock formations and seemingly endless waterfalls in the background. Then you realize that the only living things in this area are strange metallic plants that can grow through metal, and hideous man-sized arthropods with electrical powers that throw themselves at the player character in suicidal swarms. And the robots that guard the abandoned Valkyrie military base have tumorous organic growths coming out of themÖ
** The Holy City of the Eschaton is located in a rocky cavern where the walls are covered in carvings of bones and alien eyes, geysers of purple energy erupt from the ceiling, stone stairways float in midair, dark tentacles occasionally form within the shadows (sometimes forming walls to block your passage), and towering structures and statues loom in the background. And thatís not getting into the masked, robed, shrieking monstrosities that call this place homeÖ
** The Cathedral is a gargantuan edifice where AlienGeometries are in full effect: pieces of the structure float in an endless void, giant fists made of tentacles will lash out at the player from patches of dark fog (which can appear out of nowhere), and glowing fungi will spew clouds of poisonous spores if you get too close.
* ''VideoGame/SpecOpsTheLine'' takes place in a version of UsefulNotes/{{Dubai}} that is subtly this trope. The city looks mostly normal enough, putting aside the battle damage and corpses scattered everywhere, or Walker's hallucinations where the sky catches fire and hellspawn claw out of the ground. But it's also surrounded by an impossible, continuous sandstorm cutting it off from the outside world, and riven with great unexplained chasms. More important is the fact that a level usually starts with Walker and his team repelling or zip-lining down from one skyscraper to another, descending deeper into the war-torn city... and then when the next stage starts, they're back in a high place, and have to go down once more.
* ''VideoGame/DarkestDungeon'' has the titular dungeon, a combination of WombLevel and AlienGeometries. Being in it is so [[GoMadFromTheRevelation stressful]] that heroes who go in their once will refuse to return.

[[folder:Web Comics]]
* Ravenfell in ''Webcomic/OverlordOfRavenfell'' is a sentient fortress made of black crystal, created through mysterious means. Beneath it is a magically shifting maze full of traps and monsters.
* The Corpse in ''Webcomic/CogaNito'' is a blue-tinted forest studded with random chunks of orange machinery, so named because neither the trees are alive nor the machinery functioning.
* ''WebComic/{{Homestuck}}'':
** The Furthest Ring, a PlaceBeyondTime which is the home of the [[EldritchAbomination Horrorterrors]], the Green Sun (a star with the mass of two universes, which breaks several laws of physics), and the afterlife (which exists as a series of Dream Bubbles). It is said that if one were to draw an accurate map of the place, the result would be a page completely and uniformly covered in black. Time and space behave in incomprehensible ways in the Furthest Ring, and both become less reliable the longer you stay (or the further you go). For example, when Dave and Rose try to fly out to the Green Sun, [[spoiler:they end up arriving in the distant past]].
** Dream Bubbles themselves may count, as within them the conventional laws of time and space don't apply, as one can warp from memory to memory, effectively traveling forward and back in time and anywhere in space. Locations can even converge in such a way that they're a mis-match of memories of the various dreamers/dead people. For example, in one there was a mixture between Jade's island, Kanaya's home, a ruin Aradia was exploring, and some other elements.
* ''Webcomic/SluggyFreelance'' has plenty. The alternative dimensions vary from almost identical to the "normal" one to as bizarre as you like. One example: The Never is a hellish world where spirits become solid and living creatures become even more so than usual. Other Eldritch Locations can be found without even travelling between dimensions. Each dimension is surrounded by Timeless Space, where time is only carried by objects and creatures and will eventually run out for each of them, freezing it in place. The two [[TomeOfEldritchLore Tomes of Eldritch Lore]] ''Book of E-Ville'' and ''Wayang Kulit'' each contain or give access into a different kind of symbolic nightmarish world that builds itself around the thoughts of an entering character.
* The Palm Tree Ghost's realm is turning out to be [[http://danielscreations.com/ola/comics/ep0296.html more and more this way]] in ''Webcomic/OurLittleAdventure''.
* Webcomic/TalesOfTheQuestor has the Unseleighe castle of Princeling Dolan in Tir Na Nogh. Simply navigating the halls can make you arf your cookies.
* In ''Webcomic/MetroidThirdDerivative'', Planet Nemesis as named by Samus. She identified it at the source of all Phazon with the core of the planet being pure Phazon while the atmosphere and various landmasses that float above it having heavy concentrations of Phazon. A ring of Phazon meteors circle the planet destined to be thrown into space and affect other planets. Lifeforms not resistant to Phazon will die quickly on Nemesis.
* The forest in ''Webcomic/LucidSpring'' transforms into this whenever Viktor and Pacem's [[http://lucidspring.thecomicseries.com/comics/36 hallucinations]] [[http://lucidspring.thecomicseries.com/comics/37 are seen.]] The world takes on a red tint, Viktor and Pacem have wounds they don't really have, and trees ''bleed.''
* Often PlayedForLaughs in ''Webcomic/{{Nedroid}}'', including [[http://nedroid.com/2010/07/ask-your-travel-agent/ the Magma Zone]] and in [[http://nedroid.com/2009/10/fall-foliage/ this]] strip.
-->'''Reginald:''' Autumn is [[DissonantSerenity especially beautiful]] here in the Nightmare Zone.
-->'''Beartato:''' My heart is screaming with joy.
* ''Webcomic/ZebraGirl'': Sandra's house. It began to change when Sandra transformed into a demon, with shadows becoming darker and bigger, and decided to have a growth spurt on its own while Sandra was away.
[[/folder]]

[[folder:Web Original]]
* Many Wiki/{{SCP|Foundation}}s are {{Eldritch Location}}s. Some of them also qualify as {{Eldritch Abomination}}s since they are ''[[GeniusLoci alive]]''. There's also [[http://scp-wiki.wikidot.com/scp-093 the "Red Sea Object"]], which takes people into an alternate universe where [[spoiler:"a god-like being of unknown origin" instigated a massive holy war hundreds of years ago, with apocalyptic results, and now giant, immortal UncannyValley monsters roam the land, absorbing anyone who catches their attention]].
** According to [[http://www.scp-wiki.net/exploratory-mission-354-alpha this tale]], [[http://www.scp-wiki.net/scp-354 SCP-354]] leads to a world like this. Days last 43 1/2 hours, the sun is bright red, and the laws of physics don't seem to be consistent. Compasses shift daily and liquid water exists alongside liquid carbon dioxide. And there's also [[spoiler: the heavy implication that the world can erase people from existence.]]
* ''WebAnimation/HomestarRunner'':
** [[http://www.homestarrunner.com/sbemail174.html Sweet Puttin' Cakes]], a miniature golf course "every bit as messed up as the cartoon on which it's based." Residents of Free Country, USA find themselves inexplicably teleported there simply by desiring to play miniature golf. The first hole is the [[VisualPun "worm"hole]], the 18th hole has par infinity, and the only way to leave is to will yourself back to reality. When Strong Bad returns, he remarks that his mouth "[[TastesLikePurple tastes like backwards]]."
** We could go ahead and classify the Sweet Cuppin' Cakes world (which is apparently a real location) as an Eldritch Location. Just think of the inhabitants! A Strong Bad with a keyboard head, a black-and-white-talking wheelchair, a talking worm in a hole that appears to be able to warp from place to place. There's also the fact that characters can come from nowhere and that everything appears to be able to utilize hammerspace.
* ''Roleplay/RubyQuest'':
** Cold Storage.
** Much of the whole facility, really. Especially the brig, with that growing dark pit and half of its gravity reversed.
* Brian's house in ''WebVideo/MarbleHornets'' became this, thanks to [[Franchise/TheSlenderManMythos a certain someone]]. It doesn't fully follow the laws of reality and is connected to a burnt-out, industrial-looking building that is laden with even more horror.
* Sarah Waite's (yes, the last name is meaningful) dorm room at [[SuperheroSchool Whateley Academy]] in the Literature/WhateleyUniverse. It's even ''called'' the Lovecraft Room.
* WebVideo/NyxCrossing, a mysterious area that centers around a section of railroad track. According to the natives, "There is no distance," and there is a mysterious monster that stalks the characters.
* The [[http://bogleech.tumblr.com/post/74701719961/i-know-that-the-noisy-tenant-universe-the-one-where Noisy Tenant Creepypasta mythos]] is very much set in this this, given that in the core premise is that people suddenly wake up, out of nowhere, in the titular building, an endless place where space [[spoiler: and time, if the ending to Dr. Phage's Hospital is any indication]] doesn't work the same as in our reality and where there's been no exit shown in-setting.
** The place itself can be described as what would happen if Franchise/SilentHill were designed by Creator/SidAndMartyKrofftProductions , with whimsical inhabitants (An anthropomorphic hamburger chef made of rotting meat and a man-sized bacteriopage doctor with glasses and a bow-tie being the most prominent) who do horrible; horrible things to the people stuck in their realms...
** And, as a bonus, [[Website/{{Bogleech}} the creator]] has said that it's not anything as banal as another planet or another dimension, but rather something humankind has no context whatsoever for. He compared trying to explain the reason why it exists to explaining to a Pilgrim the concept of a WebAnimation/YouTubePoop without explaining computers, videos or electricity.
* ''Franchise/TheFearMythos'' has the Empty City: a possibly [[EldritchAbomination living]] city located in an alternate dimension. The city is ''huge'', changes every time you turn a corner, and is completely devoid of all souls.
* In ''Literature/TheDionaeaHouse'', the titular "dionaea house".
* Parodied in LetsPlay/ChipCheezum's LetsPlay of ''VideoGame/FiftyCentBloodOnTheSand'' with the "Fiddy Zone", a glitch where background textures fail to load during a [[ActionCommands Counter Kill]], leaving Fiddy and his opponent in a void covered by film grain.
%%* Wherever the hell it is that the WebAnimation/HappyTreeFriends universe takes place in.
* in ''Webcomic/DemonThesis'', the four main characters attend a small liberal arts college in Canada, when a [[ManipulativeBastard manipulative entity]] from another dimension begins altering reality. Only afterward do the main characters learn that their school was originally founded by an occultist who knew that the location was a place where our dimension was unusually close to and could interact with other dimensions. Said occultist intended the university to inform about the dangers of this and form a line of defense against threats, but over time the school transformed into a fairly normal university and most occult/supernatural elements have been discarded.
* ''WebVideo/CollegeSaga'' has the Cursed Structure (i.e. Babson College's Fountain of Flags). As long as it exists, mankind will continue eating vegetables.
* Prominently featured in [[http://wanderers-library.wikidot.com/the-tomb-war The Tomb War]] from ''Wiki/TheWanderersLibrary''.
* ''Literature/TheSickLand'' revolves around such a location. The titular Sick Land is a massive patch of land where strange plant life grows; people and animals that stay there for too long suffered bizarre, incurable, and fatal mutations and sickness. [[spoiler: Later it's revealed to be ''spreading'' at a slow rate, corrupting the land around it.]]
* ''Podcast/WelcomeToNightVale'', where everything paranormal is true.
* The Fineum Cuniculum from Wiki/TheWorldbuildProject probably qualifies. No one knows how it got there? Check. Mysterious engraving all down the walls of a three kilometer tunnel? Check. People randomly disappearing? Check.
* In ''Podcast/AliceIsntDead'', a long haul trucker {{Narrator}} keeps encountering paranormal places in the course of her work, from an EvilTowerOfOminousness looming in the distance to Charlatan, a traveling VanishingVillage trapped in a GroundhogDayLoop that repeatedly violates the laws of physics in increasingly disturbing ways every time she passes through.
* ''WebOriginal/ProtectorsOfThePlotContinuum'' has Headquarters, an unimaginably huge building located in the space between worlds that the PPC calls home. It's constructed from {{metafiction}}al materials like {{Plot Hole}}s and "concrit" ([[{{Pun}} concrete made from constructive criticism]]) and a portal to it exists in one specific location in each world of TheMultiverse, usually an extremely innocuous one nobody would check if they weren't specifically looking for it. Its most famous feature is that, as a defense against MarySue attacks, it's impossible to ''intentionally'' find your destination within it; PPC agents are well trained to "switch off" their minds whilst trying to get from one part of the building to another, something the simple brains of Sues are incapable of. A RunningGag in the stories is that it supposedly has a pool, but nobody, whether intentionally or not, has ever been able to find it.
* ''Literature/GreenAntarctica'': The glacier at the center of the continent is seen as one by the Tsalal, one so evil that they refuse to give it a name. While their entire culture [[SnowMeansDeath fears the color white]], it goes beyond just that. The glacier is the size of a country and half a mile thick. The dry, chilled air above it is unnaturally lit by the sun and carries sounds differently, giving it the feeling that reality is warped by its very presence. The entire thing moans and creaks as fissures open up and water erupts outward. Its edges expand and retreat like the pseudopods of a vast amoeba. There are times when the winds will trigger a sudden torrent of frigid air that splashes outward and kills everything in its path. The Tsalal cultures alternatively view it as the source of all death and suffering, hell, the abode of the gods, or even a sleeping god itself. What they can all agree on is that, when it awakens, it will bring about the end of all worlds.
[[/folder]]

[[folder:WebVideo]]
* The second chapter of [[WebVideo/MLPAnalysis Dr. Wolf's]] OriginEpisode takes place in such a place that takes the form of a library in the middle of a vast desert. Time doesn't move in the library, as Wolf doesn't age or require food, water, or rest the entire time he's there. The structure goes on forever in any direction, smells do not grow stronger or weaker anywhere or at any time, and Wolf always sensed a feeling of intrusion, as if the library sensed he and his master didn't belong and desired to expell or assimilate them.
* ''WebVideo/CarmillaTheSeries'' has the library. While more or less the entire campus is [[ExtranormalInstitute weird]], the library is above and beyond anything there, described as a sentient Escher painting with shelves and a force to be reckoned with against even the most powerful beings of the series. It stuck someone into a computer system before computers were even invented, has portals [[NotHyperbole literally]] everywhere, and a personality that ranges from [[PokeThePoodle comedically annoying]] to outright terrifying when enraged.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/JackieChanAdventures'' has the [[PrisonDimension Netherworld]], a dimension that the [[OurDemonsAreDifferent Demon]] [[EvilSorcerer Sorcerers]] were banished to by the [[Myth/ChineseMythology Eight Immortals]]. The Netherworld is a seemingly infinite void filled with floating rocks, which condemns [[SorcerousOverlord the]] [[DemonLordsAndArchdevils Demons]] to an eternity of boredom.
* The Spirit World in ''WesternAnimation/AvatarTheLastAirbender''. Shown in more detail in ''WesternAnimation/TheLegendOfKorra'', as we see such thing as [[FisherKing the terrain and inhabitants being affected by the emotions of humans inside of it]], [[GravityScrew gravity not going in any particular direction]], and [[AlienGeometry conventional concepts of location and distance being violated.]]
* The Ghost Zone in ''WesternAnimation/DannyPhantom'' which serves as an "opposite" dimension to Earth. Home to ghosts, it's a massive world where its sky is a swirl of eerie green and black. Surrounding the majority of the GZ are (usually small) floating lands--it's rare to find giant land masses since ghosts don't really need to walk--and multiple floating doors that lead to various ghostly realms, all unique, surreal, and different based on how it fits the ghostly inhabitants.
** Those large landmasses include a giant prison, an island that's the home base of an EgomaniacHunter, and the ''temple of Pandora''.
* ''WesternAnimation/SouthPark'':
** The evil half of Imaginationland. They never allow anyone or anything good to cross into their territory or else they'll be killed. Otherwise, they have no interest in war, [[PretextForWar until the terrorists attacked both halves of Imaginationland and pinned attacks on the Evil territory on the Good Imaginary Characters.]]
** The Dark Oblivion, also known as the Sunken City of R'lyeh in Coon 2 literally personifies this trope, as it is supposed to be Cthulhu's home plane.
* Possibly the emperor's palace in ''WesternAnimation/XiaolinShowdown'' as it is one of the only places where, if a Showdown is declared, the participant's clothing does ''not'' change. While this could be written off as for sake of plot (Kimiko's formal but awkward kimono made it more of a challenge for her to overcome) [[FridgeLogic it makes sense]] if you consider the societal rules of etiquette of such a place; the palace emits a spiritual counter spell to prevent other sources of magic to break such taboos.
* Although it's much more light-hearted than most, Wacky Land in ''WesternAnimation/TinyToonAdventures'' probably qualifies. The original Wacky Land, however, featured in at least one Looney Toon short and its color remake, varies from merely inexplicable to subtly menacing in its bizarreness.
* The Web in ''WesternAnimation/ReBoot''. Dark and organic looking in comparison to The Net's bright technological look.
* ''WesternAnimation/SpongeBobSquarePants'' gives us "The Fly of Despair" from "Shangheid", a dimension that only the Flying Dutchman and Squidward know about which is nothing but a dark tunnel of surreal, demonic imagery.
* ''WesternAnimation/TheRealGhostbusters''[=/=]''WesternAnimation/ExtremeGhostbusters'' made regular use of these. From the Bogeyman's home dimension to a sneak peek at the end of the world to a ghostly pirate TV station, the series enjoyed dropping the Ghostbusters in places where physics didn't work right and the architect expected the residents to be capable of phasing through walls. Some examples:
** New York in general seems to be this in their universe, it is constantly attacked by all sorts of spirits, monsters, demons, LegionsOfHell and interidmensional creatures.
** The Containment Unity evolved into this after a while. How exactly become BiggerOnTheInside is never explained but it seems to be its own immense PocketDimension, very similar in look to the Netherworld.
** The Neterworld which is basically AnotherDimension from where ghosts are original. Winstons describes it as a place full of spirits, demons and souls of people that couldnít reach other realms. The look of it varies from episode to episode (justified as itís said by Ray that it has the size of our universe) but itís mostly shown as a huge wasteland with floating boulders and mist.
** The cabinet dimension: a dimension connected to our world from a magicians cabinet is pretty much a [[FireAndBrimstoneHell hell dimension with boiling lava and snakes raining from the sky]].
* ''WesternAnimation/TheSimpsons'':
** Springfield could very well count at this point. One look at the JustForFun/SeparateSimpsonsGeographyThing page should tell you all you need to know.
** The occasionally mentioned "Springfield Mystery Spot". It's unclear if Ozzy Smith was ever seen again
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** [[PlayingWithATrope It plays with this]] via the Everfree Forest. While home to an assortment of beastly critters -- like manticores, sea serpents and cockatrices -- and weather that is consistently "dark and stormy", the ponies also regard it as horrific and unnatural because ''everything there takes care of itself''. The plants grow on their own, the animals don't need to be looked after, the weather runs without help... it's '''surreal'''! ([[PaintingTheFrostOnWindows From their point of view, anyway.]])
** Played straight in the season 2 premiere with Discord's hedge maze, which could be best described as [[Creator/MCEscher Escherian]] shrubbery. Not really a surprise when the architect is a [[RealityWarper Reality Warping]] spirit of chaos. In the second episode he turns all of Ponyville into this, [[WorldGoneMad and drives its inhabitants insane for good measure]].
** We get to follow Discord home in season five. It's a PocketDimension that does ''not'' disappoint in terms of WorldGoneMad. As such... [[UnstoppableMailman the mail is sometimes delivered *slightly* late]].
** In ''WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames'', the Twilight Sparkle who originates from the human world briefly stumbles into [[spoiler:the pony world]] [[GoMadFromTheRevelation and returns completely insane]], hinting that to regular humans, [[spoiler:the pony world itself]] is an Eldritch location.
* ''WesternAnimation/{{Superjail}}'' is full of these, especially within Superjail itself, but the [[TimePolice Time Court and Time Jail]] in "Time Police" take the cake. Considering it's a place where all living beings from all corners of the universe and time work or are tried and imprisoned, this is to be expected.
* A ''WesternAnimation/FamilyGuy'' skit shows Peter going into the 'beyond' section of 'Bed, Bath, and Beyond' which is a black void filled with various floating formulas and the like...and the coffee mugs he was looking for.
* [[WesternAnimation/InvaderZim A room with a moose. A dimension of pure dookie.]]
* ''WesternAnimation/AdventureTime'':
** The Nightosphere, home loads of creepy demons and is essentially Hell.
** The rest of the land of Ooo is pretty weird too. There's a kingdom ''made of candy'' that is ''populated by candy''.
* ''WesternAnimation/CourageTheCowardlyDog'': Nowhere, Kansas. It looks like a desert wasteland where strange monsters show up for no real reason at all. [[StealthPun And the main cast lives in the middle of it.]]
* ''WesternAnimation/RegularShow'' the park is constantly swarming with weird people, bizarre creatures, and EldritchAbomination that appear by ripping of the very fabric of reality.
* ''WesternAnimation/GravityFalls'' is a magnet for all sorts of bizarre people, creatures and entities, including a clan of macho minotaurs, a bear with more than a dozen heads, and a walking mass of rejected Halloween candy. There's also a LostWorld in the caves beneath the town, complete with still-living dinosaurs [[HumanPopsicle encased in tree-sap]].
** [[spoiler: There's also the Nightmare Realm. A decaying dimension that is the home of several interdimensional criminals and nightmares, all of which are leaked into the titular town in Weirdmagedon by Bill Cipher.]]
* Elmore from WesternAnimation/TheAmazingWorldOfGumball definitely counts, considering [[spoiler: the entire plot of an episode involves a black void where the town dumps all its mistakes.]] In fact, the aforementioned [[spoiler: black void]] counts, what with [[spoiler: its alien geometry, and how the current BigBad was permanently scarred upon exit.]]
* Many locations in ''WesternAnimation/StevenUniverse'' are peculiar or exceptional (such as the pyramid from ''Serious Steven'' or the Lunar Sea Spire in ''Cheeseburger Backpack''), but the inside of the Gem Temple easily takes the cake as one of the weirder and more frequently seen locations. The main door opens up to different locations depending on who operates it, it has multiple organs including a colossal pulsating heart, and there are corridors that twist on themselves while still maintaining a nebulous sense of gravity... to say nothing of the personalized rooms each of the gems have:
** Pearl's room is a series of freestanding waterfalls which she [[WalkOnWater stands atop]] and keeps objects inside the water. It also features what looks to be a starry sky overhead, completely ignoring the fact that this is supposed to be indoors. Further down, the waterfalls flow sideways and even upwards.
** Amethyst's room is a section of shallow purple coastline below Pearl's, littered with an assortment of objects including a palm tree and piles of gold coins. Huge crystals grow out of the walls and floor. Said coast is littered with puddles where, if you submerge yourself on one side, you emerge from the ceiling or floor of a different room.
** Garnet's room is a low, circular area floored in stone. Unlike the others it actually seems like it could feasibly be inside, but the ''veins'' of the temple feed into the walls on all sides and the ceiling is filled with bubbled gems. There's also a pit of exposed lava in the center [[KillItWithFire which sees occasional use]].
** Rose's room is a huge expanse of sparkling pink clouds that has this little thing of recreating anything its occupants ask for out of said clouds. It also operates like a computer simulation and [[OminousVisualGlitch crashes]] if asked to create anything too grandiose.
*** There's also the inside of Lion's mane, a PocketDimension that could be best described as an airless, Pink version of The Moon from Majora's Mask. It contains several things that were important to Rose, such as one of Greg's t-shirts, her sword, a video for Steven, and, formerly, [[spoiler: a bubble containing Bismuth's gem.]]
** Sardonyx's room, a black expanse that looks similar to a talk show room complete with an unseen audience, which Sardonyx can manipulate however she wants. It also only exists when Pearl and Garnet are fused as Sardonyx.
* In an episode of ''WesternAnimation/TheNewMrPeabodyAndShermanShow'' the show gets consumed by a black hole. Mr. Peabody keeps hosting from inside, a bizarre space where the rules of physics do not apply and anyone can become anything.
* In ''WesternAnimation/InfinityTrain'', a girl named Tulip is stuck on a seemingly endless train in the middle of nowhere. Tulip has spent a week traversing the cars to no avail. The train seemingly has no end, it possesses creatures which defy logic, and the cars themselves have properties which don't fit their external design. The train does have a front end, as seen in the opening, but would have to be impossibly long for Tulip to have spent as long as she has moving through cars.

[[folder:Real Life]]
* The [[EldritchLocation page quote]] from ''Zauriel'', above, well describes the [[http://en.wikipedia.org/wiki/Photosphere surface of the sun]]. The innards of a star, the depths of a [[http://en.wikipedia.org/wiki/Gas_giant gas giant]] and the vacuum of [[http://en.wikipedia.org/wiki/Outer_space deep space]] all feature mechanical properties that are incomprehensibly alien in comparison to the natural laws as we know them. Small and frail is the magical bubble in which we live and thrive.
** We can do better than that: Black holes! Also, Calabi-Yau space, the universe before the Big Bang, and pretty much anything beyond the universe. And the inside of an atom. Actually, the modern understanding of physics pretty much [[ThisIsYourPremiseOnDrugs requires a lot of drugs to understand]].
** Some of these have since put to contest - for example, the quantum physics as we know it doesn't allow an absolute singularity to form, even though General Relativity does, which may mean that no "true" black holes exist, whereas other theories challenge the idea of the Big Bang as the start of the Universe - it has already been all but disproved in the form it's being taught in schoolbooks, but the event's exact nature still eludes the scientists, and there are multiple conflicting theories without enough evidence to pick one over the others.
** Understanding the singularity that was the entire universe could require a higher level of maths than we have so far. [[http://io9.com/?_escaped_fragment_=5773158/what-really-happened-right-after-the-big-bang#!5773158/what-really-happened-right-after-the-big-bang Considering that the physics at the literal instant after the expansion began were so much different than what's in the universe now, it's not hard to conceive that.]]
** Black holes aside, neutron stars also qualify. They are so far removed from our everyday life that they are basically incomprehensible to the human mind. Their surface is so smooth that a mirror is a mountain range in comparison, and so dense and hard that a diamond is like the vacuum of outer space in comparison. The surface gravity is so strong that it very visibly bends light, and any matter will get crushed into it so hard that even its constituent particles will break and fuse into neutrons. The whole star has a mass of tens of suns and can rotate even at over a thousand revolutions per second. Because of this incomprehensibly rapid rotation speed, the star is actually a spheroid instead of a pure sphere, regardless of its density: That's how fast it rotates. And when the rotation slows down over time due to loss of energy, an unstoppable force (gravity) will acting on an immovable object (the surface of the star)... When the rotation speed has slowed down enough, the surface will give way and the ''entire'' star will restructure as a slightly less elongated spheroid... an event that's so immensely powerful that it emits an incredible amount of energy to outer space as a big flash.
** The spacetime inside of a black hole is one of the most alien regions we have yet speculated. While black holes do not "suck" things in, past the event horizon the gravity from the singularity has distorted space time so much that all paths lead deeper into the black hole. This is why light cannot escape a black hole, not because the escape velocity would exceed the speed of light, but because there is literally no path out, only deeper.
* Singularities in general are this in whatever system they might manifest in. Simply, a "singularity" is an instance in a system where the normal rules of the system are inapplicable.
* Planets with high gravity or atmospheric pressure can make for some extremely odd locations. There is one exoplanet for example that the scientists believe to be covered in boiling hot ice due to such conditions.
* Our planet itself has one in the form of the ocean, especially deep down in the trenches.
** Creatures born without what we would see as vital to living, pillars of sulfur belch toxic superheated smoke, the pressure so intense even thick steel can be crushed easily; and that's just scraping the surface of what's down there. Supposedly, there's more undiscovered species down there than there are extinct species.
** [[http://en.wikipedia.org/wiki/Undersea_lake Brine lakes]]. They are, for all intents and purposes, lakes under the ocean, complete with a shoreline. Even more [[MindScrew mind screw-y]], the density of the brine lake's surface means that any submarine that visits it can "float" on top of the denser brine lake surface. While already underwater. That's right, scientists found [[WesternAnimation/SpongeBobSquarePants Goo Lagoon]]!
** There is also the phenomenon of [[https://en.wikipedia.org/wiki/Deep-sea_gigantism deep-sea gigantism]], as well. For unknown reasons, with theories ranging from greater energy conservation, to protection against the pressure and cold of the deep sea, several animal species grow several times larger than relative species in other parts of the ocean. Such creatures include [[https://en.wikipedia.org/wiki/Giant_isopod giant isopods]], ''[[https://en.wikipedia.org/wiki/Alicella Alicella]]'', [[https://en.wikipedia.org/wiki/Japanese_spider_crab the Japanese spider crab]] and various forms of giant mollusk, such as the [[https://en.wikipedia.org/wiki/Seven-arm_octopus seven-arm octopus]] and the [[https://en.wikipedia.org/wiki/Giant_squid giant squid]]. While many of these creatures are more or less larger versions of animals found elsewhere, it only adds to the strangeness of the abyssal ocean.
* Conceptualizing how the world appears to animals with radically-different BizarreAlienSenses -- echolocation, electroreception, vibratory sense, etc -- can reveal how different even an ordinary room must seem to them.
** Any species that can perceive radio signals as sound or sight would be driven blind or deaf immediately, if not completely insane.
** Imagine getting trapped in a strange dimension where dozens or even hundreds of suns blink in and out seemingly at random, populated by [[HumansAreCthulhu titanic monsters that will brutally crush you for merely annoying them with your existence whenever you stop to take a rest.]] This could very well be how a flying insect experiences a building they have flown into.
** The universe of the fairy fly. Air is an all-encompassing jelly that it has to grab onto to fly.
* Antarctica. So many things make this place this. From four month summers and four month winters, places that look similar to Mars, hurricane winds that constantly happen with category 5 winds happening once every winter, green lights constantly appearing, it is one weird place.
** And that is not even touching on what may be preserved under the ice...
* The [[https://en.wikipedia.org/wiki/Darvaza_gas_crater Darvaza gas crater.]] Geologists broke through to a huge gas cavern, decided it was too dangerous, set it on fire, and left it burning for over ''40 years.'' It's literally called the ''gate to hell.''

* ''FanFic/TopHatsAndTigers has the Mindspace'', a place where the conscious minds go while the subconscious minds are swapping bodies. It resembles a WhiteVoidRoom, except it is checker-patterned.

* ''FanFic/TopHatsAndTigers ''FanFic/TopHatsAndTigers'' has the Mindspace'', Mindspace, a place where the conscious minds go while the subconscious minds are swapping bodies. It resembles a WhiteVoidRoom, except it is checker-patterned.



* ''TabletopGame/DungeonsAndDragons'' has a cosmology that gets weirder the further you venture from the Prime Material Plane. The transitive planes, the Astral and Ethereal Planes, are familiar enough to those who have heard of out-of-body experiences, and the Plane of Shadow is a morose DarkWorld based on the Material Plane. The Inner Planes are each dominated by one of the four classical elements, while the Outer Planes are impossibly beautiful in the case of the Upper Planes and utterly horrifying in the case of the Lower Planes. In any case, each plane in the Great Wheel has its own internal logic to it, even if in the case of Limbo that logic is "chaos." And then ''outside'' of this cosmology, perhaps on the very edge of reality, is the Far Realm. The only identifiable trait of the Far Realm is that none of it is identifiable, or even quantifiable in any way, shape or form. Simply entering it threatens a visitor's sanity - characters may sprout eyes on their palms (but not really), relive a hundred lifetimes in which their parents were Far Realm wights, or backwards speaking begin... Unsurprisingly, the Far Realm is based on the works and mythos of H.P. Lovecraft.
* The D&D settings of TabletopGame/{{Ravenloft}}, TabletopGame/{{Planescape}}, and (by way of Art Major Astrophysics) TabletopGame/{{Spelljammer}} each qualify as an EldritchLocation by their very nature.
* Terra Incognitae in ''TabletopGame/{{Scion}}'' are all the mysterious islands and lost worlds described in mythology. You can't get to them unless you yourself are mythological (i.e., have a Legend score).
** In addition, there are the Underworlds and Overworlds of the various pantheons, which operate by the rules the Gods set; the [[GeniusLoci Greater Titans]], living embodiments of a particular element such as Light, Water, Sky, Chaos, Time, etc;, and in first edition, Touchstones, the archetypal locations humanity has given meaning to (the Great Henge, the Colossus, the Dark Woods, etc.), which can be accessed through their mundane analogues. Again, you need to be mythological to get to these places, and in some cases you need to be of a certain Legend score or above to enter.
* Bardos in ''TabletopGame/GeniusTheTransgression'' are places that were once thought or believed to exist, [[ScienceMarchesOn then proved not to]], or were hoped to exist but [[IWantMyJetpack never came to pass]]. You can still travel to them if you know where to go (or stumble into them). They range from [[UsefulNotes/{{Mars}} the Martian Empire]] and [[{{Dystopia}} Tsoska]] to the Hollow Earth (recently taken over by [[StupidJetpackHitler Nazi mad scientists]]) and [[{{Cyberspace}} The Grid]].
* ''TabletopGame/ChangelingTheLost'' gives up a couple of examples.
** First is [[TheLostWoods the Hedge]], the mysterious otherspace between Earth and Faerie. Not only does it seem to map roughly to Earth in size, but it could technically be considered four-dimensional, as there's ''always'' going to be a direction that's just "towards Faerie."
** Faerie (Arcadia, Alfheim, et al.) itself is another example. A place formed purely of the magic of dreamstuff, where reality only exists because everything in it has agreed to exist and interact. This is completely disregarding the fact that many of the Realms in Arcadia are [[spoiler: [[GeniusLoci The True Fae themselves]]]].
* ''TabletopGame/BeastThePrimordial'' has the Lairs, individual to each Beast, an otherspace that is reflective of their own power (the higher their PowerStat goes, the more chambers it gains) that can be entered through any doorway.
* Pretty much everywhere outside of Illusion in TabletopGame/{{Kult}}. Weird geoscapes are the least of your worries. Gaia is the primal world where even the ''earth'' can get hungry and swallow people, Metropolis is a city filled with lunatics and Inferno is a classic {{hell}}.
* The Mad City of TabletopGame/DontRestYourHead is pretty much made of this trope.
* ''TabletopGame/{{Exalted}}'':
** The Wyld, in which reality as we know it pretty much stops working. Divided into the Bordermarches, the closest regions to normal reality, which are only mildly weird, the Middlemarches, where the laws of physics cease to be reliable and movement and distance are [[TheoryOfNarrativeCausality based more around narrative conventions than concrete measurements]], the Deep Wyld, where reality is officially [[RealityIsOutToLunch Out To Lunch]], and the Pure Chaos, which isn't so much a location as it is the unshaped, incoherent chaos outside of the universe.
** And then there are the Shadowlands, sites of past atrocities and mass murder where the border between Creation and the Underworld is just a bit thinner. Regaining Essence is hampered (unless you're a creature of the Underworld, in which case it picks up by comparison), ghosts can get around more easily, and improperly buried bodies tend to rise as zombies.
** Several of the Primordials/Yozis [[GeniusLoci are this]] as well. Things like the local geography, physical laws, and even time flow are often at the whims of the Titan that is the world. The most notable are Malfeas (the Demon King/City whose body acts as the prison of his fellows, and consists of multiple layers that constantly change shape and correspondence, and all inexplicably have the green sun of Hell right above them), Cecylene (the Endless Desert who is accessible from every layer of Malfeas and always takes ''exactly'' five days to cross) and Autochthon (who needed to deliberately modify his world body to make it habitable; the deeper parts of it show the reason for this).
** There are even a few places in Creation that work like this. One is the Well of Udr, overseen by [[NamesToRunAwayFromReallyFast the Dowager of the Irreverent Vulgate in Unrent Veils]]. It's a nexus of all possible dimensions where the strata of potential worlds collide and crash against one another, occasionally disgorging impossibilities. It's very tricky to get anywhere within its vicinity and hold onto your marbles, let alone stare into it. It's from here that the Dowager retrieved [[TheEndOfTheWorldAsWeKnowIt the Great Contagion]].
** The Elemental Poles, too, each of which is an unending font of elemental power. The trees at the Elemental Pole of Wood are infinitely tall.
* The Umbra from the ''TabletopGame/OldWorldOfDarkness'' folds in itself any sort of alternative reality and other states of being. And one has to step ''sideways'' to reach it. Sideways to reality as a whole. Furthermore, different places in the Umbra have their own laws, and the further one gets from Earth, the weirder and more hostile the worlds become, until the Deep Umbra is reached. Things are just plain ''wrong'' there. And very, ''very'' inhospitable for almost any type of earth-like life.
** And then there's the [[NamesToRunAwayFromReallyFast Black Spiral]], located in Malfeas (the Shenti of the Wyrm). Depending on [[CanonDiscontinuity which game in the cobbled together setting]] you happen to be operating in, the Black Spiral is either in [[TabletopGame/WerewolfTheApocalypse the Deep Umbra]], [[TabletopGame/ChangelingTheDreaming the Dark Dreaming]], [[TabletopGame/WraithTheOblivion the center of the Maelstrom]], or is either a convergence or a place that has doorways to all three. Put simply, it's Hell, but of course it's not that simple and entire books have been dedicated to describing, expanding, contradicting and redefining what the Black Spiral actually is. ''TabletopGame/WerewolfTheApocalypse'' describes it as the tormented mind of the Wyrm itself. There are even allusions that it is the dessicated husk of ancient Malfeas from ''TabletopGame/{{Exalted}}''. It breaks, reshapes and fundamentally corrupts anyone unlucky enough to find themselves there, and we're talking mentally, physically and spiritually, all at once. It is the home, seat of power, [[GeniusLoci dying body]] and [[AndIMustScream prison]] of the Wyrm, the primordial force of entropy in the setting's universe. One tribe of werewolves are called the [[NamesToRunAwayFromReallyFast Black Spiral Dancers]]. Guess what they do for an initiation rite?
* The Shadow Realm of the ''TabletopGame/NewWorldOfDarkness'' is more a DarkWorld. But if you go deep enough, you get to the parts of the Shadow Realm taken over by lords among the Spirits, and then the rules disappear.
* ''TabletopGame/{{Warhammer 40000}}''.
** Aside from the mentions in the literature section above, ''everything'' in the Eye of Terror ends up this way, as well as the Maelstrom (basically a mini Eye of Terror that doesn't even have the decency of an explanation of how it started). Any place a Warp Rift is opened starts to slowly turn into one of these, and if the rift is left unchecked it can end up turning the entire planet into a [[WorldOfChaos Daemon World]]. And that's just what happens when a ''tiny fraction'' of the Warp leaks into the real world...
** The Dark City of Commorragh, home of the Dark Eldar, is also an example, being an enormous collection of realms located inside the Webway (a network of warded tunnels in the Warp), linked together with portals. It's basically Escher on crack and populated entirely by sadistic murder-elves. To make matters worse, in some parts the wards that separate the Webway from the Warp have become weakened, leading to things like districts where shadows come to life and things from outside reality lurk.
** Necron tomb worlds are examples of non-Warp related eldritch locations. The Necrons' mastery over science allows them to create spaces that follow a higher order of geometry than we're used to, resulting in things like buildings that are bigger on the inside.
** Even Eldar Craftworlds are such. They are not planet sized spaceships, but rather entire fleets that gathered together for mutual protection, linked by gates and warps that are tangental to the Webway as a whole. Any given door doesn't open onto whatever's on the other side, but rather to wherever you are wanting to go in the Craftworld itself. On top of this, the physical linkages joining the Craftworld is made from, effectively, psychic powers turned into a solid, called Wraithbone - and acting as a conduit for the souls of every Eldar whose Soulstone was recovered. And at the core of each Craftworld is an area called the Dome of the Crystal Seers. The apparent statues in here aren't - they're the solidified bodies of the greatest farseers of the craftworld, converted into solid wraithbone.
* ''TabletopGame/MagicTheGathering'':
** The locations associated with its resident {{Eldritch Abomination}}s, the Eldrazi; in particular, a combination of solitude and proximity to the Eye of Ugin, which sealed the Eldrazi within the plane Zendikar, cost the planeswalker Sarkhan Vol his sanity for a time, and it wasn't until several months after leaving that he had fully recovered.
** Innistrad isn't as bad as Zendikar [[spoiler:until Nahiri summons Emrakul to it]] but there's clearly something ''off'' with its moon. The moon of Innistrad is a powerful source of mana of multiple types and is responsible for the existence of Innistrad's various supernatural beings: angels, werewolves, [[spoiler:and the vampires since Edgar Markov became the first vampire by drinking angel blood]]. The Helvault, a nigh indestructible prison for demons, was created from a fragment of the moon. [[spoiler:The moon itself eventually becomes Emrakul's prison.]]
* In ''TabletopGame/{{Nephilim}}'', Selenim are capable of creating Realms, pocket universes that exist according to their will, which turn out like this trope.
* Most of the ''TabletopGame/JAGSWonderland'' setting has this in spades. There are eight layers of reality, referred to as "Chessboards." You live on Chessboard Zero. Chessboard One is more or less identical, except everyone's kind of nuts. Chessboard Two is a run-down, dilapidated DarkWorld. Chessboards Three through Six are a sliding scale of CloudCuckooLand and this trope. And Chessboard Seven can barely be called reality by any stretch.
* ''TabletopGame/ArkhamHorror'' allows the players to visit the locations from H.P. Lovecraft's mythos, like the Plateau Of Leng, Yuggoth, and R'lyeh.
* In ''TabletopGame/{{Dragonstar}}'' there is a large region of space outside Imperial space known as the Dark Zone. Few who venture into it ever return, but the few who do speak of darkness and terror. It's also the setting's counterpart to the Far Realm in that it's the home of mind flayers (their original home, it is speculated) and other aberrations.
* In ''TabletopGame/BleakWorld'' this is what the Death Beyond Death is, if a ghost dies they go to a place where they are in constant pain, but can never gain the release of going insane. The whole area is guarded by [[EldritchAbomination The Caretaker]] which is liquid field of darkness filled with constantly disappearing eyes and mouths
* In the game ''Magical Burst'', Youma, the creatures {{Magical Girl}}s fight, frequently surround themselves with a distortion in the tapestry of the world called a Nightmare. For most people, this manifests as a vague feeling of dread, owing to how {{Muggles}} cannot even ''perceive'' Youma or their influence, much less hurt them. For Magical Girls and those attuned to magic, the Nightmare appears as an increasingly surreal region of distorted reality, getting weirder and weirder as one nears the Youma.
* The titular setting of ''TabletopGame/BetrayalAtHouseOnTheHill'' always has a random layout, and can have things such as walls that devour you and spit you out elsewhere.
* The cosmos of ''TabletopGame/{{Nobilis}}'' is pretty much made up of Eldritch Locations, all of which run on their own set of rules - ''including'' mundane Earth, which is a fantasy the Earth created for itself after the trauma that destroyed the dinosaurs, a way for it to deny the existence of karma and thus the belief that it deserved that trauma. It's self-maintaining, self-rationalising... and overstretched, as it's getting far too complex to sustain.
[[/folder]]

[[folder:Tropes]]
* The SugarBowl is a strange form of this. It may be depicted as a genuinely nice place, or as it was in the article. However, there's no denying that a place with licorice trees and structurally sound buildings of candy would belong here.
** Likewise, ''VideoGame/AnimalCrossing'' definitely exists in one of these [[FridgeLogic if you think about it hard enough]]. This has been well-documented in many {{Dark Fic}}s.
* The ClownCarBase also fits this trope in a way, especially when the trope is {{lampshade|Hanging}}d, revealing it to be not just a perspective oddity, but a genuine physically disproportionate building.
* A LevelAte is a place where terrain is GiantFood, often a humorous version of this sort of thing.
* Many {{Lost World}}s are this in a nutshell.
* A DarkWorld can function as an Eldritch Location when it's explicitly evil or "wrong", but a few morality neutral Dark Places are natural "night side" reality counterparts to our own.
* A PlaceBeyondTime is this by its very nature.
* An EldritchStarship can easily be an Eldritch Location with a hyperdrive.
[[/folder]]

[[folder:Video Games]]
* ''Franchise/ShinMegamiTenseiPersona'':
** The series in general has a more benevolent but still bizarre example in the Velvet Room, a room covered ceiling-to-floor in blue velvet that exists outside of time and space, changes appearances with each game, and sometimes isn't even a room (in ''3'' it's an ever-ascending elevator car, and in ''4'' it's a limousine traveling through space.) All of its denizens - the master, Igor, the pianist and singer in the first two games, the painter in ''2'', Elizabeth and Theodore in ''3'', Margaret in ''4'', and Caroline and Justine in ''5'' - are all AmbiguouslyHuman.
** The original ''VideoGame/{{Persona}}'' has a slew of them, courtesy of most of the game being set in [[spoiler:a parallel dimension formed from the thoughts of IllGirl Maki Sonomura, courtesy of a device called the DEVA System]]. The most prominent in the game would be [[spoiler:Avidya World, the embodiment of Maki's darkest thoughts and the VeryDefinitelyFinalDungeon]]. ''Your own high school'' can also get turned into one if you partake the optional Snow Queen Quest instead: if you find a mask inside the school's gymnasium, the spirit inheriting it turns it into a frozen ice palace surrounded by three arcane towers, and you have to trek all three and collect twelve mirror shards in order to break the spell.
** While most of the dungeons in the ''VideoGame/{{Persona 2}}'' duology are set in the real world, [[YourMindMakesItReal the ever-omnipresent ability to make rumors into reality]] add an extra layer of strangeness to them all. The most straightforward example is [[spoiler:Monado Mandala, Nyarlathotep's domain,]], which you only see in the second half of the duology (''Eternal Punishment''): it exists in a space-like area, with pathways and mandalas of light serving as its sole building bricks.
** ''VideoGame/{{Persona 3}}'' has Tartarus (pictured above), an [[ChaosArchitecture ever-changing]] tower that only exists during the Dark Hour, and acts as a pathway from the world of Death and the Collective Unconsciousness from which humanity's Shadows can manifest. [[UpdatedRerelease FES]] adds the Abyss of Time as its inverted twin.
** ''VideoGame/{{Persona 4}}'' has rather the creepy TV World, which once again, is the Collective Unconsciousness being forced to manifest via the "mind" of mass media. [[spoiler:Subverted in the True Ending, where lifting the final veil of deceit from mankind's heart turns the Collective Unconsciousness itself into the GhibliHills.]]
** ''VideoGame/{{Persona 5}}'' has the Palace, a region inside the [[MentalWorld Collective Unconsciousness]] that can create a mirror of reality based on the warped desires of humans, and you can only get there with a mysterious phone app. The underground maze of Mementos serves as the Palace for most of humanity, but those with especially potent, twisted desires can create their own palaces that reflect their state of mind, much like the dungeons of the Midnight Channel in ''Persona 4.'' The creators of the more unique palaces serve as the major bosses for the game.
* Bacterian, the BigBad of the ''VideoGame/{{Gradius}}'' series qualifies: He is a GeniusLoci HiveMind that uses psychic powers to control his fleets. Every time he's defeated, the pieces of him regenerate to form new Bacterians. Gofer, Venom, Zelos, and some other large Bacterians also qualify.
* The Pfhor ship of ''VideoGame/{{Marathon}}'' seems to be mostly organic, with green liquid all over the place. The gravity is low, too. The creepy music doesn't help either. ''Marathon's'' game engine actually ''encourages'' non-Euclidean level design because of the way it implements overpasses. Several levels have passageways that pass through each other as an intentional MindScrew, and some third-party mapmakers have taken it to a very confusing extreme.
* ''Franchise/SilentHill'' features a weird variation of this trope through the eponymous town, which may cross over with, unusually, EldritchAbomination and GeniusLoci. Though its exact nature is [[MindScrew very much up for debate]], it appears to be abandoned and shrouded in fog, day and night come randomly, and a nightmarish [[DarkWorld "otherworld"]] version of the town lurks beneath the surface and can overtake you at any moment. The otherworld draws its form [[SelfInflictedHell from people's minds]], sometimes [[PsychologicalTormentZone the protagonists]] and sometimes [[RealityWarper another character entirely]]; quite a few [[EpilepticTrees epileptic forests]] have grown from trying to explain it all. It's worth pointing out that DJ Bobby Ricks, one character in ''VideoGame/SilentHillDownpour'' has pointed out that the town has 'rules,' and it is not keen on people disobeying it. If the town wants you to stay inside, if it wants you to learn something, you will. Possibly for eternity, as one character has been stuck there, delivering mail to parties unknown (possibly from the town itself) for 200 years. Even the apparent deity or demon worshiped by the town's resident cult, [[ScaryAmoralReligion The Order]], might just be the town acting upon the cult members' beliefs and desires.
* ''VideoGame/{{MOTHER}}''
** In ''[[VideoGame/CognitiveDissonance MOTHER: Cognitive Dissonance]]'', you are sent into one of these by Niiue to distract Giygas, where everything is red, there's chaotic forces of PSI, and the alien himself waiting in the center of it all with the Devil's Machine.
** In ''VideoGame/EarthBound'', once the Devil's Machine is turned off, it's implied that Giygas might just be huge and dimension-warping enough to be not just an EldritchAbomination, but one of these in his own right. And before that, Ness and Jeff get to visit Moonside, which also qualifies.
** ''VideoGame/{{Mother 3}}'' has the Empire Pork Building, which is an unusual sort of eldritch location. Every floor you visit seems normal in its own right, at least as far as the Mother series goes. A lake full of hippos, a hall full of bathrooms, a construction site, etc. But they're all so disconnected and irrelevant to each other, and supposedly each one is the 100th floor.
* ''Franchise/TheLegendOfZelda'':
** The various incarnations of the LostWoods in the ''Zelda'' games: they either turn off your minimap, making navigation extremely difficult, or in ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle of Seasons]]'', one place is even completely off the map, plus the place where Like-Likes fall from the sky. In ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' it's implied that anyone who isn't of TheFairFolk would tend to become hopelessly lost, eventually turning into skeletal imps doomed to haunt the forest forever.
** ''VideoGame/TheLegendOfZeldaSpiritTracks'' has the final area, the Dark Realm. Accessed through a dark portal that can only be found with a magic compass, it basically looks like Van Gogh's ''Starry Night'' in a black hole. Beneath the train tracks is some kind of strange, smoky/watery "ground" that gives way to a completely different landscape right beneath it.
** The setting of ''VideoGame/TheLegendOfZeldaMajorasMask'' is a pseudo alternate dimension called Termina, with several oddities (like the physics of Stone Tower Temple, as well as the SurrealHorror elements involving the Moon and the distinct regions) that violate many logics. The fact that the game's titular villain is a reality warping, psychopathic EldritchAbomination contributes to this as well.
* The inner sections of the Pyxis (A.K.A the Box) from ''VideoGame/CliveBarkersJericho''.
* ''VideoGame/{{Chzo|Mythos}}'' is both this and an EldritchAbomination, a pain elemental who satiates himself with tortured victims trapped inside his labyrinthine corridors for all eternity.
* The interaction of {{Hyperspace|IsAScaryPlace}} and Pathspace in ''VideoGame/ImmortalDefense'' produces one of these. From Pathspace, Hyperspace looks like a twisty path across a 2D plane, and from Hyperspace, Pathspace is the home of vindictive demigods who rain psychic death upon unwary travelers. [[spoiler: The ''protagonist'' is one of these demigods.]]
* ''VideoGame/DwarfFortress'':
** [[http://www.bay12forums.com/smf/index.php?topic=61507.msg1400676#msg1400676 The Adamantine Spire]], a.k.a. the Adamantine Space Elevator. The weirdest part is that even when other people tried to recreate it using the same worldgen seed, it didn't show up. Current theories are that it's due to [[GoodBadBugs interference from old save data]].
** FridgeHorror: Considering what adamantine veins like the spire usually [[TheLegionsOfHell contain,]] it looks like whatever counts as Heaven in the Dorf 'verse is in for some serious [[UnusualEuphemism Fun.]]
** Some of the more convoluted succession forts such as ''LetsPlay/{{Battlefailed}}'' become this. Battlefields had the temporally locked dwarves in the arena, Headshoots had the room outside of space, etc.
** And then there's the evil biomes. Rains of blood and FogOfDoom that causes any living thing exposed to it a horribly painful death if they're lucky or turns them into a [[HumanoidAbomination thrall]] if they're not, eyeballs and tentacles growing out of the ground, a 50/50 chance of anything that dies there spontaneously reaminating into a zombie if the body isn't [[ChunkySalsaRule thoroughly destroyed]] and native wildlife that would make [[VideoGame/{{Doom}} Doomguy]] feel right at home.
* ''Franchise/{{Pokemon}}'':
** The Distortion World from ''[[VideoGame/PokemonDiamondAndPearl Pokémon Platinum]]'' falls under this. Floating masses of land in a giant vortex, giant plants that sprout randomly out of nowhere, disappearing platforms, and waterfalls that float up are just a few features to be found. And that the ''only'' thing living in there is the EldritchAbomination known as Giratina. There's also the immense GravityScrew of the Distortion World. The waterfall isn't the only thing that goes the wrong way there; the Distortion World is the ''only'' place in the ''whole main series'' where you navigate by jumping onto those floating platforms and ''walking sideways''. It's also impossible to ride your bike there.
** Ultra Space, the home dimension of the Ultra Beasts from ''VideoGame/PokemonSunAndMoon''. We don't see too much of it, just a multicolored barren cavern, lit up despite the absence of any apparent light source, filled with various Nihilego (read:toxic parasitic jellyfish made of shapeshifting glass) floating around and occasionally phasing in and out of existence. The characters comment that the air feels strange and it's hard to breathe properly. The Rotom Pokedex, which is otherwise always chatty and displays a map of the area, is completely silent and its screen is filled with static, completely inoperable.
** In ''VideoGame/PokemonUltraSunAndUltraMoon'', you see more Ultra Spaces and you can even fight the Ultra Beasts on their Home Turf. From what the trailers have shown, Kartana (read:living origami who can cut through steel) resides in a strange forest, Buzzwole (read:muscular humanoid mosquito) resides in one of the least eldritch of them as it looks more like a jungle in broad daylight (though that may invoke [[DaylightHorror another trope]]) and Xurkitree resides in what looks like the inside of a chaotic machine.
* The Dark Rift from ''VideoGame/SkiesOfArcadia'', a high-pressure storm system that can't be crossed the way regular rifts can even with a fully-upgraded ship and remains even after the other rifts have calmed. Inside it is an alien landscape full of corridors that connect in odd ways, strangely-oriented landmasses, and plants and creatures very much unlike the ones seen anywhere else in the game. At its heart is a moon stone that doesn't match any of Arcadia's 6 moons.
* ''VideoGame/{{Skullgirls}}'':
** Gehenna, a WombLevel set before a lake of blood whose background features several eyes imbedded into the level that follow the characters as they fight. [[HellIsThatSound Yes, that's screaming you can hear in the soundtrack.]]
** Nightmare Crest is a twisted version of the familiar Maplecrest stage that acts as a setting for the game's BattleInTheCentreOfTheMind stages - the surroundings are muted and greyscale, the people that are normally bright and colourful on Maplecrest are formless shades with glowing white eyes and while the black leaves are frozen in mid-fall, the sky above is a rapidly-swirling red and purple storm.
* ''Franchise/{{Castlevania}}'':
** It's an Eldritch Location and houses several {{Eldritch Abomination}}s to boot. The discrepancy that crops up between the games is {{lampshade|Hanging}}d and {{handwav|ing}}ed with a comment that the castle is "[[ChaosArchitecture a creature of chaos]]." The castle can take many shapes and forms, picking and choosing when and if it wants to follow the laws of physics.
** In ''VideoGame/CastlevaniaSymphonyOfTheNight''), the whole castle ''has an inverted duplicate'' revealed halfway through. You and the monsters fall towards and walk around on the ceiling. All the furniture is still on the floor. It is never explained why a second castle just appears out of the clouds, nor why it's upside down. And then there's the two mirrored split castles in ''VideoGame/CastlevaniaHarmonyOfDissonance'', which are somehow both the extension of Maxim's will.
** Dracula's demon castle continues to follow tradition in the [[VideoGame/CastlevaniaLordsOfShadow2 Lords of Shadow]] subseries, with that twist that an entire city gets built onto the ruins at one point. While being on top of the castle usually isn't a problem, it does mean that someone can occasionally walk right outside of their office and wind up right in the seat of Dracula's power.
* ''Franchise/KingdomHearts'':
** Both [[VeryDefinitelyFinalDungeon final levels]] of ''Franchise/KingdomHearts I'' and ''II''. The one from [[VideoGame/KingdomHearts the first game]], appropriately titled The End Of The World, is basically the remains of any and every world destroyed by TheHeartless, and the one from [[VideoGame/KingdomHeartsII the second game]], The World That Never Was is a dark city overrun by Heartless overlooked by the warped castle that is the headquarters of Organization XIII, and its ''[[WeirdMoon moon]]'' is [[MacGuffinLocation the heart of reality itself,]] [[TitleDrop Kingdom Hearts]] (or at least, a functional replica).
** In fact, the concept of the worlds makes them Eldritch Locations: they are apparently separated, but are described as sharing the same skies. All the worlds used to be one large world, but it was shattered in the Keyblade War, leaving only shards behind, forever separated by metaphysical barriers that few can traverse.
** The Realm of Darkness is its own twisted version of reality. As the name suggests, it's pretty dark, much of it seemingly made up of gray rocks with cracks out of which ghostly blue light faintly shines. There is no sky, no horizon, just pure blackness. Seemingly no living things other than the Heartless (if they count as such). But the most disturbing thing about it is that ''time'' doesn't flow in the Realm of Darkness. Characters who are trapped there do not age and do not sleep, and have no way of marking the passage of time. [[spoiler:Aqua is surprised to hear that she's been trapped in there for ''over ten years'' from the perspective of everyone else.]] And the worlds that fall to darkness? They get trapped in the Realm as well, transformed into twisted caricatures of themselves floating in a void that only barely obey the laws of physics.
* ''VideoGame/ShinMegamiTenseiStrangeJourney'' has the [[DarkWorld Schwarzwelt]]. It is effectively a [[NegativeSpaceWedgie void]] over Antarctica where [[HellGate demons appear]], overwriting Earth with their own reality. The Investigation Team's mission is to analyze and nullify the Schwarzwelt before it can consume the entire world. The game over screen shows what happens if your character dies...it ain't pretty. The fun part is that the UN sent cameras into the Schwarzwelt during the planning stages...and ''nobody'' believed the results (one of them was a ''shopping mall''). Turns out they were all accurate (but you don't want to eat the food in the shopping mall...).
* ''[[VideoGame/ShinMegamiTenseiIIINocturne Shin Megami Tensei: Nocturne]]'' mostly takes place within the Vortex World, a chaotic, demon infested realm that the Earth reverts to when it comes time for a new world order to be decided. Naturally, it's up to you to shape it as you see fit. For bonus points, it's a truly literal form of TokyoIsTheCenterOfTheUniverse.
* And in ''VideoGame/ShinMegamiTenseiIV'', we have the final dungeons for Law and Chaos, respectively: Purgatorium and Lucifer Palace. The Monochrome Forest also counts, as well as the various Demon Domains littered around Tokyo.
* Xen, the "border-world" from ''VideoGame/HalfLife1''. It seems to consist of a bunch of small rocky islands floating in the middle of a greenish void, and yet apparently has gravity independent of those islands and a breathable atmosphere. It's also inhabited, although [[AllThereInTheManual the fluff]] indicates that the current inhabitants are not native to the dimension, and came from someplace else.
* Every time you fly through Bydo Dimension in ''VideoGame/RType'', especially the MindScrew territory of the final stages of ''Delta'' and, well, ''Final''. To put in specific terms, the Bydo Dimension in ''Delta'', which is depicted in the picture above, looks like a twisted version of our world with babies encased in crystals, upside-down buildings, huge strands of DNA, and a weird forest of Bydo Trees. The Bydo Dimension in ''Final'' is an abyss full of fluid inhabited by eyeballs and the creature implied to be the real source of the Bydo. The Bydo Tree forest bit also appears in ''Final'' as a hidden stage. There is also a stage in ''Final'' that takes place in a weird dimension where there is only the player, a slug Bydo named Nomemayer, and particles of light that can turn anything and anyone into a Bydo. And there's Anti-Space, a dimension ''created'' by some Bydo guys named Gridlock.
* On the final floor of ''[[VideoGame/{{Dgeneration}} D/Generation]]'', what once looked like an ordinary office building (albeit with hyperactive security measures) suddenly turns into a bizarre surreal nightmare thanks to the title entity. There's also a headless guy.
* ''Franchise/DragonAge'':
** The Fade, the place people (except dwarves) go when they dream, full of spirits and demons and doubling as Heaven, Hell and everything in between. Characters are trapped in their own "mini-Hells" ([[IronicHell reflecting their own lives]]), the sky is full of floating mountains (heavily implied to be other, infinitely large hells) and the [[{{Hell}} Black City]] is visible wherever you go.
** And in the DLC ''Witch Hunt,'' Morrigan implies that beyond the Fade there are places that are even stranger where [[spoiler: she's keeping her Demon Baby safe from her evil mom.]]
** Amgarrak Thaig, the titular location of ''Golems of Amgarrak'' is definitely one, protected from the outside by a maze of shifting mist and having Lyrium Wells that were designed to phase-shift people into alternate versions of the Thaig in order to better safeguard its secrets.
** The sequel has [[spoiler:Kirkwall. Yes, that's right: the main setting. It's subtle, though; you can go through the whole game just thinking the whole place is a [[CrapsackWorld Crapsack City-State]], but certain notes you find indicate that not only is the Veil unnaturally thin over the entire area, entire neighborhoods are constructed in the shapes of blood magic sigils, there are likely lakes of blood beneath the streets that still haven't dried, but demons are actively drawn to the place like flies to the point where they occasionally hunt non-mages because ''there's too much competition''. And that's ''before'' you factor in [[SealedEvilInACan Corypheus']] [[TheCorruption corrupting]] presence from his Grey Warden Prison in the nearby Vimmark Mountains.]] It - or very nearby - is actually where [[spoiler: the magisters entered the Black City (sacrificing hundreds of slaves in a blood ritual in the process) and were transformed, like Corypheus, into darkspawn, causing the Blights.]]
** The [[spoiler: Primeval Thaig]] is definitely one, [[spoiler: built by prehistoric Dwarves that worshipped a pantheon of deities, constructed using magic thus giving it some degree of AlienGeometry, posessing a unique form of Red Lyrium running throughout the structure itself and inhabited by creatures like the Profane that Varric claims were supposed to be ''myth''. It was also the location where Hawke and company first encountered the [[ArtefactOfDoom Lyrium Idol]]]].
** In an older Creator/BioWare example, the Spirit World of ''VideoGame/JadeEmpire'' is similarly weird.
* ''VideoGame/{{Homeworld}}: Cataclysm'''s Beast is said to come from "Outside".
* The NES game ''VideoGame/TheMagicOfScheherazade'' has the EldritchAbomination Goragora [[SealedEvilInACan trapped in ancient times]] in the "Dark World" (not to be confused with a DarkWorld), and the villain threatening to release it once more. He eventually learns the hard way that EvilIsNotAToy, and begs the heroes to enter the Dark World and keep it from escaping. Beyond the gate and past the PointOfNoReturn, the VeryDefinitelyFinalDungeon looks like a starswept black abyss with walls and columns made out of transparent bubbles.
* The GBA and PSP remakes of ''VideoGame/FinalFantasyI'' have the four special dungeons that change floor permutation with every visit. Furthermore, some of these floors have environments that should not be able to exist in a subterranean environment, such as overworlds, {{Floating Continent}}s, and thriving towns that look just like the ones on the surface, ''complete with shops and inns''.
* In ''VideoGame/FinalFantasyII'', [[spoiler:the Jade Passage and Pandaemonium]].
* In ''VideoGame/FinalFantasyIX'':
** [[spoiler:Terra, a parasitic other planet, actually inserted itself into Gaia long ago and is feeding off the planet from the inside.]] Creepy.
** Another present in the same game is [[spoiler: Memoria, a world formed from the collective memory of the entire planet.]]
** The Hill of Despair where the party fights Necorn which is apparently the [[spoiler: Afterlife.]]
* ''VideoGame/FinalFantasyV'' has the [[VeryDefinitelyFinalDungeon Cleft of Dimensions]], which is a patchwork of areas earlier swallowed up in the Void and home to many {{Eldritch Abomination}}s including the game's two NintendoHard {{Bonus Boss}}es. The UpdatedRerelease added the [[BonusDungeon Sealed Temple]], home to even more {{Bonus Boss}}es, including the HumanoidAbomination who the legendary weapons were crafted specifically to fight.
* ''VideoGame/FinalFantasyXI'' has a few that qualify, and they all tend to follow the "islands floating in nothingness" style:
** The Promyvion areas appear to be corrupted, shadowy versions of other existing areas, topped off with haunting music and freakish looking monsters.
** The Walk of Echoes is an area of disconnected structures floating in nothingness. [[spoiler: It pretty much exists outside of time, and Atomos himself can be seen in the sky at all times.]]
** The added Provenance areas, [[spoiler: which are described as being the place where the source of all life comes from.]]
* Although featuring fewer locations than one might expect, ''VideoGame/FinalFantasyXIV'' still features some notable examples, especially those found in the ''Heavensward'' expansion. Perhaps the most obviously eldritch is [[spoiler: the Aery, Nidhogg's lair, which is a ruined Avalonian city held together in a storm of aetheric energy fueled by the dragon's blinding rage.]]
** The strangest location has to be the Palace Of the Dead (making a cameo from TacticsOgre); accessible only through a strange portal in the Black Shroud, the Palace of the Dead is an ever shifting maze filled with monsters, traps, and strange magical items that only seem to function within. The entire palace is filled with a gloom that saps the strength of anyone who enters, reducing them to Level 1 and rendering their equipment useless. Only by condensing one's life force into weapons and armor made of magic can one hope to survive. What's even stranger is how, while decending in the palace, players will rapidly gain levels to the point of exceeding their job level back in the 'real world'. Prior to Stormblood, this even meant learning spells and abilities meant for max level characters while still being low leveled in the "real world". The deeper you go in the Palace, the stranger things become; eventually falling apart into a series of pathways in a misty white void. The 200th floor features [[spoiler:a tranquil looking bench underlooking a tree, in a place completely devoid of enemies. Some players have joked that this is the Palace inviting you to be it's latest denizen. Thankfully it doesn't object if you refuse.]]
* The inside of [[EldritchAbomination Sin]] in ''VideoGame/FinalFantasyX''.
* In ''VideoGame/{{Xenogears}}'', [[spoiler:Deus, already an EldritchAbomination, becomes an enormous EldritchLocation in its own right.]]
* The Dead Sea from ''VideoGame/ChronoCross''. It's the site of a massive TimeCrash, where the canceled BadFuture from ''VideoGame/ChronoTrigger'' tried to reassert itself over Chronopolis. Waves of water, forever frozen in time, wash over the wreckage of the city, and at the heart is the Tower of Geddon, a conglomeration of locations from said canceled timeline haphazardly mashed together. Much later, you also go to the Darkness Beyond Time, where cancelled timelines are sent [[spoiler:and where the Time Devourer lurks]].
* Its predecessor ''VideoGame/ChronoTrigger'' already had the [[PlaceBeyondTime End of Time]], the place where all possible time lines meet. As far as eldritch locations go, it's actually fairly harmless. The UpdatedRerelease added a few more such as the [[BonusDungeon Dimensional Vortexes]], areas where time and space are essentially broken. The Darkness Beyond Time also makes an appearance.
* In ''VideoGame/WildArms2'', [[spoiler:the Encroaching Parallel Universe "Kuiper Belt" is one of the most terrifying examples yet]].
* In the original ''VideoGame/PhantasyStar'' series, the very Algol star system it takes place in is an enormous lock for a dreadful SealedEvilInACan. And the lock isn't exactly completely intact.
* The titular planet in ''VideoGame/{{Albion}}'' looks like some alien world with primitive civilizations at first. Until it is revealed that it operates under completely different laws the Earth does. [[spoiler:The fact that it's actually a sentient (benevolent) being, has something to do with it]].
* The tunnels under ''VideoGame/PathwaysIntoDarkness'''s pyramid are actually the nightmares of a catatonic EldritchAbomination made real.
* Several places in the ''VideoGame/{{Warcraft}}'' universe qualify.
** Chief among them is Outland. It was formed when the planet Draenor was torn apart by multiple interdimensional gateways being opened on the surface. It's now a continent with several different ecosystems, some of which are healthy and normal, or at least, [[PatchworkMap as normal as the rest of this universe]]. However, the [[FloatingContinent continent]] is surrounded by, rather than an ocean, an edge, and if you walk off it you fall into nothingness. It also has an AlienSky, which is sunless but otherwise mysteriously normal in some zones, but looks like energy cascading through space in other places. In several places there are {{Floating Island}}s, some of which have water perpetually falling off them with no source.
** The Netherstorm. Not only is it even more surreal than the rest of Outland, being just a collection of massive floating rocks instead of a single land mass, no one knows where it came from. Every other zone has a clear analogue on Draenor but the Netherstorm doesn't.
** The Maelstrom. A eternal whirlpool full of unstable energies surrounded by an eternal hurricane that was formed when the Well of Eternity was destroyed. The black dragon Deathwing used it as a portal back to Azeroth, almost causing the world to blow up. The constant attention of several powerful shamans is required to keep the world from falling apart through it.
** Deepholm. It can be reached by flying into the Maelstrom. It is the home of earth elementals and other creatures native to the elemental plane, so it's not ''supposed'' to be comfortable to flesh-and-blood creatures like playable races. It is a massive cave with a rock-based ecosystem, rock pillars that float in the air, and spires that regularly explode and reform. Most of the elemental planes are odd like this, but with another element in the place of rock.
** Karazhan is a large black tower in the mostly empty Deadwind Pass. It was once home to Medivh, The Last Guardian, and sits atop a point where every ley line (think veins, but instead of blood it's magic) in the entire world intersects. Time itself gets lost within Karazhan, allowing visions of past, future and other worlds to pop in and out unexpectedly. One of Medivh's theories is that the Deadwind Pass was formed because someone would eventually build a tower there, rather than the tower being built where the Pass was. Also, there is an inverted Karazhan under the main one, and the main one exists in at least two parallel universes at once. There's also the odder features inside and around the tower.
* The World of Mammon in ''VideoGame/{{Quest 64}}''. The environment drastically changes with each transition, doors never lead to the same place twice, the sky is always the wrong the color, and the music is creepy as heck. The inhabitants are just as unnerving: among them are [[LivingStatue Living Statues]] that have more than a passing resemblance to [[Series/DoctorWho the Weeping Angels]]. Of course, the entire place is the prison/domain of a demonic EldritchAbomination.
* ''VideoGame/{{Minecraft}}'' has a couple of these:
** The Nether is a [[HyperspaceIsAScaryPlace deliberate example]]. Once you finish the mining tech tree and craft a diamond pickaxe, you can build an obsidian HellGate and enter a skyless world filled with steep cliffs, lava lakes, and giant jellyfish that spit fireballs at you while flying out of reach of your arrows. Not only will your compass spin around aimlessly, so will your watch. However, any distance traveled inside the Nether is multiplied by eight once you return to the normal world, so it can be used to travel long distances relatively quickly, once you finish digging tunnels and building bridges.
** The End, a single barren island floating in an infinite void. It's home to the Endermen, and can only be accessed by portals deep in underground ruins... and can only be exited by defeating the [[FinalBoss Ender Dragon]].
** An [[MinusWorld unintentional version]] of this is the Far Lands. In the pre-release versions of Minecraft, travelling roughly 12 million meters in any one direction makes the game generate areas like [[http://hydra-media.cursecdn.com/minecraft.gamepedia.com/c/cc/12550821line.png?version=6d6925e5d08789a5400fcd256252a8dd this]], in addition to huge amounts of lag and "stuttery" movement. Travel even farther, and around 32 million meters, physics and lighting just stop working altogether. The Far Lands were acknowledged by the creators, who [[AscendedGlitch planned to keep them in the game]], but changes to the way terrain is generated effectively removed them before release.
** ''VideoGame/{{Thaumcraft}}'', a popular GameMod, contains a more traditional example, called the Outer Lands. You get there by [[spoiler:performing a ritual called "Opening the Eye" on a floating Eldritch Obelisk]]. When you arrive, you'll find [[spoiler:a dark maze filled with Eldritch Abominations, with a boss at the end]].
* ''VideoGame/TheBreach'' starts off on an ordinary spaceship, but towards the end things start to ''shift'' into a mountainous region filled with yellow mist and glowing glyphs.
* ''VideoGame/MassEffect2'' has [[spoiler:the derelict Reaper, which can still indoctrinate despite being dead for ''37 million years'', a not-so-derelict Collector vessel and finally the Collector Base, an immense space station located in the accretion disc at the heart of the galaxy, which serves as TheVeryDefinitelyFinalDungeon. The vessel is even creepier than the base itself since in the latter, you are almost continuously under attack, while in the former, about the first two thirds of the mission consist of exploration without enemy contact - [[{{NothingIsScarier}} which, in this environment, only makes it worse]].]]
* The Subspace of "Subspace Emissary" in ''[[VideoGame/SuperSmashBros Super Smash Bros. Brawl]]'' is this coupled with AmazingTechnicolorBattlefield. And it only gets weirder when the parts of the regular world that were dragged into the Subspace are assembled into the [[MarathonLevel Great Maze.]]
** In ''Wii U/3DS'', [[spoiler:Master Core itself turns into one of these, named 'Master Fortress'.]]
* ''VideoGame/TheLegendOfSpyro'' has Convexity, a gateway between the main world and the Dark Realms, occupied by the Dark Master. It's the location of the final boss battle, featuring floating platforms and strange whale-like creatures with tentacles.
* ''VideoGame/ElShaddaiAscensionOfTheMetatron'' has the Tower, where the majority of the game takes place. Each floor of the tower is ruled by a fallen angel and is essentially its own pocket universe where that angel and its followers live. Locations range from a burned-out wasteland to a cutesy cartoon-like world of colorful blocks and balloons to a futuristic {{Tron}}-like cityscape (complete with cycle combat!) to an underwater world. There's also the Darkness, a location that corrupts everything that falls into it [[spoiler:and is where the souls of the angels' followers end up instead of Heaven]].
* ''VideoGame/FallenLondon'':
** The Neath from the first game and its spinoff ''VideoGame/SunlessSea''. There is a theory that the giant cavern is the skull of a dead god. It is very difficult to die there because it's downstream of Hell. Finding one's way around it can be ''literally'' maddening. An unnerving number of the places you visit are probably alive. You might accidentally walk into someone else's memories. People there keep tigers as pets, make wine out of mushrooms, and play a boyish game based upon stabbing other people. The islands far beyond London keep swapping places when you aren't looking, making maps useless after enough time. You can become used to much of the Neath, but there are a couple places in it that are... different.
** In Polythreme, inanimate objects come alive. A Clay Man explains, "IN POLYTHREME THE BED I SLEPT ON WAS A SLAVE. THE ROOM WHERE I SLEPT WAS HACKED FROM SCREAMING STONE. THE WATER I DRANK BEGGED ME TO STOP. THEY PAID ME IN COIN THAT PLOTTED MY DOWNFALL. THE MEMORIES ARE TROUBLING. THIS PLACE IS BETTER."
** The Iron Republic is a place of true freedom - not even the tyranny of nature rules there. Everything is in a constant state of flux, and the straightforwards interface becomes deranged ramblings. Writing a report on it will net you something either completely blank or ''explosive'', and the punctuation's practically guaranteed to try to eat you. Gather enough protesters and you can literally protest something into existence, or make it disappear completely. The laws of mathematics change every Thursday, which makes accounting just plain intolerable. And even then, what Thursday is probably also changes constantly. And, since it's in both Fallen London and Sunless Sea, you can even ''buy items for the wrong game''[[labelnote:*]]It's been documented you can buy Supplies and Fuel, vital for Sunless Sea but absolutely useless in Fallen London, for no reason at all beyond the fact it's the Iron Republic[[/labelnote]]. The only law is, there is no law.
** The Cave of the Nadir. Lost to history for quite a while, a pain to find even with an enormous archaeological team, pretty much ''everyone'' has an interest in knowing its location, and once there you might wish you never found it. Why? [[spoiler:The entire cave is Irrigo, a mysterious and horribly dangerous color resembling a deep, intense violet. It soaks into you, and stays with you like an insidious radiation, eating away at your memories, your thoughts, and eventually your mind itself. The cavern is full of individuals of all kinds and species that have completely lost themselves, and are completely unable to remember anything, or think clearly. Prolonged exposure will cause your skull to ''grow bone over your eye sockets'' in a futile effort to stop it. Forgotten memories bounce around the place with no rhyme or reason, and make you remember things you never experienced before departing just as quickly as they came. And if you forget your own name, [[AndIMustScream you can never, ever leave]]. And there are theories this color is what makes the entire Neath an Eldritch Location in itself]].
** Irem was strange. Irem is strange. Irem will be strange. It's basically what happens when you sail straight to the edge of dreams (coming in from an actual physical place), and found a city in the border. Or what happens when you will do that in the future. Either way, it hasn't been founded yet, but you can visit it, and have a jolly good time over there, and come back with not much trouble. You'll have been there when the time comes. And yes, in case you haven't noticed TimeTravelTenseTrouble is a ''huge problem'' when writing port reports.
** The Twin Castles of Frostfound, up North where the ice and cold reign. These two are very, very deeply linked to the Gods of the Zee, and entering them will piss them off, with no seeming reason given. Entering any of the two will start eating away at your mind, particularly your memories and stories, until there's nothing left of you. And a little less unnervingly (which shows by what standards we're playing by now), space inside the castles just doesn't seem to work right. Bringing a certain crewmate inside will lead to you spotting him disappearing through the wall never to be seen again, for example. And if you want to enter, there's no doors. You have to close your eyes and go forward, and you'll just... be there, in a series of chambers that will eat at your mind and/or possessions.
** Avid Horizon. No matter how you twist and turn in your road, if you travel North for long enough, you will end up here. There is no way to continue further North. It's an enormous, unbreachable gate with an odd rubbery texture, guarded by two statues, all of a deep Gant colour. Gant being what remains when all other colors have been eaten. Everyone, even your fungal cargo, is unnerved when approaching the place. The fake stars above start flickering like they're going out as you approach. And the gate isn't a thing. It's a Law. And sometimes, when the guardians aren't aware... the law can be breached. [[spoiler:And somehow, ''somehow'', it leads to outer space]].
** Kingeater Castle. Nobody has any idea what the hell is up with the place. People can willingly give up their sanity, and even their past and future. The sense of a great impending mistake pervades the air as you approach. Praying to the most mysterious of the three local deity-like beings can occasionally send you there for no given reason. Something about the place just conducts you towards the most horrible decisions. And a terrible hunger seems to reign all throughout it. It's quite remarkable that even in a place like the Neath, where the strangest of all things get explanations and are considered normal, this is one place that is still feared and unexplained.
** And in this literal ocean of madness, there manages to be an inversion to this trope in the form of Aestival. A simple, quiet island of sand and rocks and some vegetation. Nothing more to it, because the Sun shines from outside and into it through a hole in the Neath, and the Neath's local variety of weirdness tends to react [[WeakenedByTheLight very badly]] to it. Shame this also includes people who've lived in the Neath for any significant length of time.
** The zeefloor proves itself just as strange with the ''Zubmariner'' expansion. It rearranges itself ''much'' more often than the surface does, the wildlife goes from merely being more awful than surface versions of the same to making absolutely no biological sense, it occasionally grows bubbles of impossible colors with terrifying effects, random clouds of pure darkness can appear from out of nowhere, it occasionally has a gigantic eye that can be sailed into and contains MindScrew incarnate and the shadow is so intense ''[[EldritchAbomination things]]'' can slither out of it every now and then. And then there's the various Abysses, where [[HumanoidAbomination the Lady in Black]] can be found... Ironically enough, the underwater ''ports'' are all relatively normal in comparison to some of the above. The strangest of them by our standards ([[ElephantGraveyard the Gant Pole]], [[CyberneticsEatYourSoul Anthe]], [[WombLevel Nook]] and [[StarfishAlien Aigul]]) are just par for the course by the time you can submerge, and the strangest for the Neathers (Hideaway, a city atop a GiantEnemyCrab) is outright ''normal''.
** Not only does the Neath contain several of these locations, it's the only place where the usual pathways to yet another, ''much'' bigger Eldritch Location will work as such. The place is Parabola, and the pathways are dreams, Prisoner's Honey, and mirrors. Yes, normal mirrors, and any sort of dream you have will take you to Parabola for a brief time. And people that are going entirely insane and having the most horrible nightmares have been known to just... ''stumble'' into the place by accident with no way out for a long time. Its outer borders, the Mirror-Marches, look like an endless jungle with oddly familiar ruins of the previous four cities, Earthen fauna that acts a little too strangely, and with framed mirrors partially embedded into the ground everywhere. These mirrors are the other side of regular mirrors back in the Neath, and you can peer back into reality through them. The laws of reality are just a bit more tenuous here, and you can pull off certain tricks that even the Neath's lax rules don't allow. It's also stated that deeper into Parabola, things get much stranger, including things like a marsh where the light of every snuffed candle comes alive. The rulers here are known as the Fingerkings, [[spoiler:who are tiny, flying snakes with RealityWarper powers within Parabola and who like to [[GrandTheftMe snatch up dreamers' bodies to check out reality]], and also make deals with people to give them strange powers, being particularly fond of stage magicians]]. Cats love the place, however (though they despise the Fingerkings), probably because they get to decide their forms in here and [[PantheraAwesome enjoy being big, badass cats]].
* The Otherworld, the final location and lair to the FinalBoss from ''VideoGame/{{Miitopia}}''. It is a strange, allegedly cursed place in which, according to [[spoiler:the Ex-Dark Lord]], no regular human could survive. It is a psychedelic and eerie place populated by sentient rocks and aliens, with weird undulating lines dancing in front of a deep purple void and the floor is in blurry colors with occastional star patterns racing through it. Its most distinctive feature though is the countless luminescent stolen Mii facial features seen floating in the background and the occasional purple bubble floating in the foreground. It is also unclear whever the Otherworld is set in space or in another dimension.
* The '''entire''' world of ''VideoGame/{{Limbo}}''. It's dark (as in pitch-black save for the rare spot of light), silent, and [[EverythingTryingToKillYou literally everything is after your blood]]. [[PuppeteerParasite Or your brains]].
* ''VideoGame/{{STALKER}}'' is set in the Zone of Exclusion surrounding the Chernobyl Nuclear Power Plant after its infamous meltdown. Referred to simply as "the Zone", said location has become a place when only the most heavily-armed and foolhardy ever set foot due to massive amounts of both leftover nuclear radiation and ''[[RealityIsOutToLunch incredibly weird shit]]''. Aside from all the "normal" stuff - wild dogs, mutants, bandits, military troops, radiation pockets, and hostile factions - you have the anomalies: getting too close to what looks like a patch of empty air can [[LudicrousGibs reduce you to bloody chunks]]; that lightning-looking ball hovering over the ground can electrocute you; that patch of air that looks like it's shimmering in the sun can spit out a jet of fire that will burn you alive instantly if you're not protected enough. And those are just the ''obvious'' hazards. At one point, you encounter an endlessly looping room. At another, [[AlienGeometries you find a lake that is also a hill, and that lake flows several yards into the air]]. If you're caught improperly sheltered during a [[RedSkyTakeWarning blowout]], you'll find it's even more bizarre and even more dangerous than ever. [[YourHeadAsplode Briefly.]] [[BilingualBonus If you understand Russian]], the other stalkers have some... ''interesting'' stories to tell by the campfires, too. And lastly, the artifacts, your main source of income and stat boosts for the games, are are formed by the previously mentioned anomalies, so they're found exclusively around these areas.
* ''Franchise/MortalKombat'':
** The Netherrealm, which is home to the demonic Oni and is generally about the most depressing place you can be. Of course, it is the MK universe's equivalent of Hell.
** There's also the Chaosrealm, where, as the name would imply, nothing makes any sense whatsoever. The prevailing theme of the realm and all of its inhabitants is that they adamantly refuse to conform to any set of rules (especially the laws of physics). It is even implied at one point in [[VideoGame/MortalKombatDeception Deception's]] Konquest mode that natives of other realms who stay there long enough will inevitably be driven insane as their mind struggles to make sense of the place.
* ''VideoGame/BlazBlue'':
** The Boundary can be classified as this - a nexus for all timelines, and so chock-full of nastiness and {{mindrape}} that mere ''entry'' can destroy you in some shape or form. Precisely eight beings are known to have traveled through the Boundary, either for TimeTravel or some other reason.
** Ragna the Bloodedge: Involuntarily dumped into the Cauldron at Kagutsuchi by Nu-13. [[spoiler:Not much is known happens to him at this point, though it's assumed that his soul was either ripped apart by the Boundary or became a new Black Beast, smelted in the cauldron and later released. He later does it again in Chrono Phantasma, this time in a controlled scenario with Rachel's assistance, and emerges 100 years in the past and eventually becomes Bloodedge.]]
** Nu-13: Tosses herself into the Cauldron at Kagutsuchi together with Ragna after impaling them both with her Calamity Sword. [[spoiler:It's never revealed what happens to her at this point, though it's assumed that she either was torn apart by the Boundary or was smelted into a new Black Beast before the ResetButton was pushed.]]
** Lotte Carmine: Willfully entered the Boundary ForScience [[GoMadFromTheRevelation Goes insane due to exposure to forbidden knowledge]], loses his body soon thereafter and becomes Arakune.
** Litchi Faye-Ling: Momentarily enters the Boundary to gain the knowledge and power to save Lotte above. Gains telekinesis and the ability to tap into the power of the Boundrary, but is slowly developing memory loss symptoms and is in danger of turning into another Arakune.
** Hakumen[[spoiler:/Jin Kisaragi]]: [[spoiler:Jumps into the Cauldron after Ragna and Nu-13. Goes back 100 years in time, succumbs to injuries sustained prior to dive, but otherwise emerges unharmed - all mental damages relate to transfer to the Susano'o Unit shortly thereafter. Also engages Yuuki Terumi in a duel as a diversion so Jubei and Claudius Alucard can banish Terumi to the Boundary, [[HeroicSacrifice in the process sealing away Hakumen as well]]. Emerges 90 years later at 20% power, but has remained physically and mentally sound due to sheer force of will.]]
** Yuuki Terumi: [[spoiler:Banished to the Boundary during engagement with Hakumen. Lost the artificial body he was possessing at the time. Effects on mental state indeterminate due to prior batshit insanity.]]
** Relius Clover: [[spoiler:Enters the Cauldron for reasons unknown. Emerges 80 years later, physically unharmed; memories are jumbled during transfer, but are quickly reset to pre-jump state.]]
** Makoto Nanaya: [[spoiler:Loses her consciousness in proximity to Cauldron at Ibukido due to Prime Field Device activity and emerges in the ''Wheel of Fortune'' timeline. Travels back to ''Continuum Shift'' timeline with aid of Rachel Alucard. Zero physical and mental degradation in both transfers.]]
* ''[=BlazBlue's=]'' predecessor, ''VideoGame/GuiltyGear'', has the Backyard, a parallel world teeming with information which also serves as the source of magical energy for the world. Entry for most people into the Backyard is dangerous: without "tuning" to the Backyard's frequency, they risk being destroyed by the information inside it.
* Historia in ''VideoGame/RadiantHistoria'', [[spoiler:as well as Granorg's Royal Hall. Its final boss Apocrypha also looks something like this, albeit shrunk.]]
* ''Franchise/TheElderScrolls'':
** The series' universe itself. Starting with the AlienSky itself, the sun and stars are not typical balls of burning gas but holes punctured in reality by escaping spirits during the creation of Mundus, the mortal plane, and magic flows through them into Mundus which is visible in the night sky as nebulae. The [[WeirdMoon two moons]] of Nirn (the planet within Mundus that all of the action to date in the series' has taken place on) are said to be the rotting and sundered "flesh divinity" of Lorkhan (also known by [[IHaveManyNames other names]]), the [[TheMaker creator god]] of Mundus who was [[GodIsDead "killed"]] by the other spirits who aided in creation, now known as the [[OurGodsAreDifferent Aedra]]. The planets visible from Nirn are not typical planets, but are the planes and "flesh divinity" of the eight most significant of these Aedra. It is said that these forms all appear as they do because [[YouCannotGraspTheTrueForm it is the only way for a mortal's mind to comprehend it]]. That said, this information primarily comes from subjective in-universe sources who often conflict with each other, as the series is well-known for its [[UnreliableCanon intentionally contradictory lore]]. Just like many [[ScienceMarchesOn discredited beliefs]] in [[{{RealLife}} the real world]], the "true nature" of the TES universe could very much be as "normal"/conventional as our real universe is, or it could be something else entirely.
** The various planes of Oblivion, the "infinite void" surrounding Mundus, may be the [[GeniusLoci physical forms]] of the [[OurGodsAreDifferent Daedric Princes]] they are associated with. They are not bound to any of the laws of nature and physics that bind Mundus, and are subject to change on the whim of the associated Prince. Even [[YearInsideHourOutside time does not flow normally]] within Oblivion, though the exact details often vary. For example, when [[TheGoodKing Emperor Uriel Septim VII]] was imprisoned there by his EvilChancellor CourtMage Jagar Tharn for 10 Nirn years, he did not age a day. For specific details on the planes of the Daedric Princes, see the series' [[Characters/TheElderScrollsDaedra "Daedra" Characters]] sub-page.
** The island of Artaeum combines this with {{Bizarrchitecture}} and AlienGeometries. Artaeum is the home of the [[TheOrder Psijic Order]], a powerful MagicalSociety and the oldest monastic order in Tamriel. Artaeum shifts continuously either at random or by decree of the Psijiic Council. It can also be made to disappear ''entirely'' from Mundus.
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]''
*** In the ''Dawnguard'' DLC, you visit the [[SpiritWorld Soul Cairn]], a realm of Oblivion created by the Ideal Masters, a group of immortal beings who [[WasOnceAMan were once powerful mortal sorcerers]]. The Ideal Masters have a HorrorHunger for souls, especially the "Black" souls of sapient beings, and they [[YourSoulIsMine are always seeking to claim more]]. The Ideal Masters prefer [[EnergyBeing forms of pure energy]], as they find physical forms to be "too limiting". However, they will take the form of giant crystalline soul gems within the Soul Cairn, and can drain the souls of mortals who venture too close. Other Soul Cairn inhabitants include the captured souls [[FateWorseThanDeath doomed to spend eternity there]], grotesque undead monstrosities that randomly appear from the ground, and a {{Dracolich}} [[NinjaPirateZombieRobot zombie dragon necromancer]].
*** In the ''Dragonborn'' DLC, you visit Apocrypha, the realm of Hermaeus Mora, the Daedric Prince of Knowledge (with a particular specialty in [[TheseAreThingsManWasNotMeantToKnow Things Man Was Not Meant To Know]]. Reading one of Mora's "[[TomeOfEldritchLore Black Books]]" causes you to be ensnared by a tentacle that formed from letters which float off the pages, pulling you inside. The realm itself is a place Cthulhu would find comfy. All the walls are made of books, the water is slime and sprouts tentacles to attack you if you get too close, there are invisible monsters roaming the halls and sea mutants in the slime, certain areas have darkness that can kill you, and the architecture isn't necessarily static. On a more meta note, it also does not help that the area is notoriously [[GameBreakingBug glitchy]] so that when the when the layout of certain tunnels shifts, the Dovahkiin tends to clip and fall through the floors and walls into the deadly slime. But if you brave these horrors, the Black Books will grant you amazing powers.
* Astral Chaos in the ''VideoGame/SoulSeries'' is a timeless alternate dimension from which the Soul Swords originate, and is filled with lost souls and an EldritchAbomination or two.
* The Labyrinth of Deceit in ''VideoGame/KidIcarusUprising'' is a maze full of fake walls, holographic asteroid belts, gravity inversion switches, and disappearing paths. And even when you're not caught up in an illusion, the walls, ceilings, and floors are decorated... odd. And did we mention it's found inside a [[OurWormholesAreDifferent Space Rift]]?
** [[spoiler: And then Chapter 21 has the Chaos Vortex, which is basically the Labyrinth of Deceit taken UpToEleven. It contains replicas of ''every'' enemy from all four factions, [[LivingShadow living shadows]] that attack, eye-shaped portals that spring up out of nowhere, pieces of buildings that randomly move about, floating islands. It's just weird.]]
* ''VideoGame/Kirby64TheCrystalShards'' has [[spoiler:Dark Star, a planet made of [[EldritchAbomination Dark Matter]] and the {{Very Definitely Final Dungeon}}. Not much time is spent inside of it, but its red skies, ribbons of darkness and crystalline hexagonal tiles give it this vibe and make it significantly more alien than any of the planets visited in the game.]]
* Hang Castle in ''VideoGame/SonicHeroes'', but especially its interior, Mystic Mansion. In the daytime, it's a normal abandoned castle, albeit an exceptionally large one. At night, the exteriors seemingly extend endlessly in all directions, and gravity doesn't always point downwards. Once inside, rooms suddenly change topography (sometimes when Sonic and the others are in it), things pop in and out from impossible places, there seems to be a physical upside-down version of the mansion underneath the normal one, dumbwaiter tracks twist and contort while zooming off at high speeds, Eggman's robots pop up out of thin air (presumably intentionally), and what is supposed to be a well is full of weird vaguely water-like texture in all directions with a few small brick platforms suspended in it.
* The ''Franchise/TombRaider'' series has had a few of these, but two that stand out are the Atlantean Temple in the first game and ''[[VideoGame/TombRaider Anniversary]]'', and ''Tomb Raider II'''s Floating Islands level. In the first example, the deeper into the complex you go, the more organic the architecture gets, until the walls are made of pulsing muscles. The Floating Islands are...well, ExactlyWhatItSaysOnTheTin, a series of floating islands inside of a Chinese tomb.
* ''VideoGame/TheSecretWorld'' features several:
** One of the more benevolent examples arrives in the form of Agartha, a hollow Earth filled with branching trees, giant robotic caretakers, and a lot of bees, perpetually lit by sourceless golden light. It's actually a divine biocomputer and font of anima (i.e. magic), and it also functions as a weird PortalNetwork usable only by those touched by Agartha's bees (it "precipitates a messy discord" in the flesh of the uninitiated).
** On the other side of the metaphysical spectrum, places severely impacted by [[TheCorruption the Filth]] begin to corrode reality, opening starry portals to distant and lifeless space. One of the worst areas is "The Breach," an excavation site in Transylvania that's been converted into a massive wellspring of the Filth by the Orochi Group and the Vampire Army. We see another such location during the prologue, where Ground Zero for the Filth bomb detonated in the Tokyo subway has all but completely lost contact with reality. For the player, such locations are also a doorway to...
** ...the Dreaming Prison. A semi-metaphysical landscape of glittering black-sanded beaches under a midnight sky with a broken moon and blocks of white ice drifting overhead, dotted with massive cuboid shapes of an unknown material called the Gaia Engines. These things ''literally'' keep the world running, though Freddy Beaumont implies they can be used for "[[TakeOverTheWorld other things]]." For good measure, it's also a prison for the monstrous beings that produce the Filth, kept dormant by the Engines, and it's up to you to either reinforce the prison or help the inmates escape.
** The City of the Sun God. Built by Pharaoh Akhenaten in Egypt as an act of devotion to the Aten, it's on another Filth wellspring, and the results have turned into into a gathering point for just about any malevolent force in the area. The ''portals to {{Hell}}'' open in two corners of the valley don't help, but they're ''not the most eldritch things in the area''. The centerpiece of the alley is the Black Pyramid, Akehnaten's resting place. Thanks to a combination of arcane magic and the Filth's reality-warping influence, massive chambers and hallways fit inside despite clearly being too large for the structure. One of these rooms is a literally bottomless pit - above which the dormant [[HumanoidAbomination Akhenaten]] slumbers.
** In the update "The Vanishing of Tyler Freeborn", the Mist surrounding Solomon Island is revealed to be hiding one of these. [[spoiler:Specifically, the Red Sargassum Dream, a twisted recreation of the town of Kingsmouth under a perpetual midnight sky, inhabited only by Filth-infected versions of the locals.]]
** The Hell Dimensions are a FireAndBrimstoneHell that's almost completely starved of anima. The creatures inhabiting the place, identified in human folklore as demons, frequently try to steal anima from Earth, occasionally through [[HellOnEarth demonic invasions]] but more commonly by tempting humans into [[DealWithTheDevil signing over their souls]]. The environment in Hell is toxic to humans and capable of turning blood to metal, such that only those touched by Agartha's bees can survive down there. Theodore Wicker, a human mage interested in Hell, had to perform heavy magical alterations on his body (including tearing his heart out) in order to adapt to Hell's conditions, such that life on Earth became uncomfortable for him; he wound up leading a rebellion against [[{{Satan}} Eblis]].
* ''VideoGame/StarWarsTheOldRepublic'' has the Voss [[IDontLikeTheSoundOfThatPlace Nightmare Lands]], filled with barren soil, twisted trees, mutated wildlife, and a pervasive corruption field that reduces the weak of mind (read: everyone but the player characters) into violent psychopaths or blubbering vegetables. As an added bonus, there are no less than 5 quests available to deal with {{Eldritch Abomination}}s.
* The ''VideoGame/{{Thief}}'' series contains a few of these, notably Constantine's mansion, the Old Quarter and the Lost City in ''[[VideoGame/ThiefTheDarkProject The Dark Project]]'', and Shalebridge Cradle in ''[[VideoGame/ThiefDeadlyShadows Deadly Shadows]]''.
* ''Franchise/SuperMarioBros'':
** The level Matter Splatter Galaxy in ''VideoGame/SuperMarioGalaxy'', due to the unusual physics of the solid objects and grounds that only appear when a particular field of matter gets close enough. The green-colored background of the level is even more surreal.
** Compared to the rest of the DreamLand, Dream's Deep from ''VideoGame/MarioAndLuigiDreamTeam'' counts. While most of the other dream locations are more-or-less surreal versions of the area Luigi sleeps in, this place is implied to take on the appearance of the sleeper's subconcious. In this case, it's a large purple space with floating neon Luigi faces and holograms, with quotes representing his thoughts flying around. [[AlienGeometries There are places where going off on one end of the screen takes you to another location of another, and even how this works doesn't have to be constant. On the first visit, (the dreamed version of) Luigi goes missing until the boss fight, yet if you leave before said boss, he's back and claims that he was right behind Mario the entire time.]] And finally, the only "natural" inhabitants are Dark Blocks, [[SpritePolygonMix which are animated in actual 3D]] in contrast to game's "pseudo [=3D=]" sprites seen in the normal battle mode.
** The whole Violet Sector of ''VideoGame/PaperMarioColorSplash''. We have a sentient ocean, a whirlpool that never goes away, an area of the ocean that is pitch black in broad daylight, and smoke coming from out of nowhere. Except for the first thing, everything is a result of things going on in the Alternate World.
* In ''VideoGame/FarCry3'', it's implied that there is something subtly but fundamentally ''wrong'' with the Rook Islands. The extremely hostile animal life, the gradual madness that consumes anyone who goes into the jungle, the strange and mystical relics, the drugs giving accurate prophetic visions, [[spoiler: the ink demon]], and so on. It's not obvious, but the islands are ''doing things'' to the people who spend time there. However, due to the game's MaybeMagicMaybeMundane nature, it's left unanswered whether there is actually something wrong with the place, or if it's just the player character [[{{SanitySlippage}} losing his mind to drugs and trauma]].
* ''Videogame/KerbalSpaceProgram'' has Jool, which at first just looks like a green Jupiter. And then you get anywhere remotely close to it, and physics start getting more than a little odd, and only get nastier as your ship gets close, culminating in it spontaneously exploding while you're still several hundred miles from the surface. And then your poor astronauts fall in, and [[WreakingHavok their limbs]] [[BodyHorror flail in impossible ways]] before they simply die. And that's the ''best'' case scenario; there's the occasional tale of ships that survive entry getting flung out of the galaxy at FTL speeds. Of course, it's not actually meant to be that way - it's just glitchy as hell - but the fans have latched on to the first interpretation to match with a certain GoodBadBug being blamed on an EldritchAbomination. Funnily enough, it's this exact same weirdness that makes it completely immune to any and all attempts to (further) glitch it out, and not from lack of trying. And since many of those glitches tend to destroy entire planets...
* ''VideoGame/{{Dishonored}}'' has the aptly named Void, which consists of a series of islands floating in space, depicting fragments of real world buildings and characters frozen in time. It's the home of [[HumanoidAbomination the Outsider]], who will quite effortlessly and arbitrarily drag people there to mess with them or grant them magical powers or both, and it seems to bend to his whims.
* You've got your Shadow Lairs in ''Videogame/SpiralKnights'', but after the boss(es) are defeated, your team is whisked away to a frighteningly empty monochrome (especially compared to the colorful gameworld) tunnel called the Unknown Passage. Some really creepy ambience plays in the background as you prepare for a wave of enemies, and when they arrive, you'll fight TheSwarm.
* The [[OrphanageOfFear Edgewood Home for Lost Children]] in ''VideoGame/OurDarkerPurpose''. Inanimate objects come to often-malevolent life, the architecture shifts unpredictably, and the plants are twisted if not actively vicious. It's hinted that the lands outside the gate are ''even worse''.
* The ''VideoGame/MetroidPrimeTrilogy'' features a few planets that are more than a little twisted because of [[TheCorruption Phazon]] exposure.
** In ''VideoGame/MetroidPrime2Echoes'', Aether was split into two when it got hit by a Phazon meteor (which, in ''VideoGame/MetroidPrime3Corruption'', is revealed to be a Leviathan from planet Phaaze): the light world had some catastrophic global changes, such as plains becoming barren or a woodland jungle flooding but the serious issue was the creation of [[DarkWorld Dark Aether]] which has an atmosphere so toxic it kills any non native in seconds (eating through almost any sheilding), truly sinister landscapes and the locals are always chaotic evil and really don't like light.
** Phaaze, the Phazon planet, [[spoiler: by virtue of being a sentient being that is trying to spread and corrupt other planets]]. It also has some very organic looking natural structures. Lore surrounding the planet suggests that it's an EldritchAbomination existing in a higher dimension, with the planet merely being its form in our Universe. Phaaze is the source of all Phazon, which seems connected no matter how far apart its fragments are. Leviathans are birthed inside its crust, and Phazon versions of the Ing from the previous game appear as common enemies.
* ''{{VideoGame/Rift}}'' features the Planes of Water and Death. The first of these 2 Planes the Plane of Death appeared in the raid: Endless Eclipse and was not only a combination of bones and flesh yet most bizzarely the sky has an sun in an eclipse surrounded by Eldritch symbols.
** The Plane of Water is going to make it's debut in an upcoming expansion and it's first zone Goboro Reef is a sea with spaces of Water carved out of the zone due to the zone's creator waking up(the Plane of Water is actually a DreamLand) leaving walls of water rippling vertically around those waterless spaces.
** The Plane of Water's second zone Draumheim is a city with an ocean suspended over it(due to the inside of the city being effected by the aforementioned water being carved out of the Plane of Water) filled with every creature from everyone's dreams with the southern portion being a desert containing a forest and a bigger and nastier copy of Port Scion ruled by the Lord of Nightmares himself.
** The Plane of Water's third zone Tarkin Glacier is less of an EldritchLocation than the other two due to being a SlippySlideyIceWorld with the mountain at the end being filled with minature Air rifts with it's peaks being floating rocks which are the only Eldritch things about the zone despite the developers' claims of a heavy Lovecraftian influence.
* The ''VideoGame/DarkSouls'' franchise has a number of these:
** The Abyss could practically have a whole entry to itself:
*** The Abyss in New Londo. It's black. And that's pretty much it. No light. No landscape. No horizon. No ground. Just black in every direction, going on forever. You can only survive in the place by wearing a particular magic ring; if you don't, you just fall. Forever. [[spoiler:It was born out of concentrated human essence. That's right, apparently the source of this empty nothingness is ''humanity itself''.]]
*** The ''Artorias of the Abyss'' DLC takes you back to the Abyss, which is represented as an utterly lightless cavern filled with bizarre pitch-black ghosts that look like concentrated Humanity. The worst part is that the Abyss is clearly spreading outward, as strange blue-black ichor covers the surrounding landscape, getting more prevalent the closer to the Abyss one gets.
*** The Abyss is back in ''Dark Souls II'', now called the Dark Chasm of Old, where it can only be entered as a spirit, and contains spirits of other warriors endlessly wandering its cave-like halls killing anything they see, alongside these weird tree-sorcerer things. And the boss of the area is a creepy angelic being called the Darklurker, which absolutely nothing is known about.
** The Crystal Cavern. It's a huge cave that is home to bizarre monsters and invisible platforms. The sheer wrongness of the place seems to reflect the madness of the being who made the cave his sanctuary, Seath the Scaleless.
** Ash Lake. It's a small remnant of what the world looked like before the Fire and before the Lords defeated the Everlasting Dragons. It's a seemingly endless expanse of grey water, with gigantic, utterly massive trees extending up beyond the clouds that blanket the sky. All you find down here are a scarce few enemies, and even the small beach you explore is huge compared to most other areas in the game. The sheer scale, uniformity, and silence of the place, combined with the mournful music, just creates a feeling of emptiness.
** The Old Chaos in ''Crown of the Ivory King''. Beneath the frozen land of Eleum Loyce lies a giant inferno with tree roots branching all over the place yet not burning, and the battle takes place on an inexplicably floating stone platform far above an endless sea of flame, with doorways that contain fiery portals that spawn corrupted knights. [[spoiler:The roots and branches are meant to evoke Lost Izalith from the first game, where the Bed of Chaos was fought. It seems to be hinted that the Old Chaos is the Bed in a new form.]]
** The Untended Graves in the third game are a near-exact replica of [[spoiler:the tutorial area and Firelink Shrine... except crawling with much more powerful Undead, Black Knights, and covered in pitch darkness. One character's dialogue implies that the place is a look into an AlternateUniverse where the Fire has finally died and the Age of Dark has come. Since Firelink Shrine can only be accessed via bonfire-warping, while the Untended Graves can be reached on foot from the rest of the game, this has disturbing implications.]]
** The entire realm of Lothric is implied to be one in ''Dark Souls III'', as it's an amalgamation of different lands once ruled over by their respective Lords of Cinder, summoned across time. Even more so in the Kiln of the First Flame, which seems to be made up of an illogical jumble of buildings and architecture haphazardly piled on top of one another across an endless plain of ash and half-melted spires of rock.
* [[OurVampiresAreDifferent The Forest of Einnashe]] in ''Franchise/{{Nasuverse}}'', first mentioned in ''{{VisualNovel/Tsukihime}}''. It's a forest that acts like a vampire, in that it eats every person and animal that comes upon it. And yes, it can move and hunt ''cities'' on its own. Good thing it's only shown itself every 50 years.
* ''Franchise/{{Nasuverse}}'' also gives us [[MentalWorld Reality Marbles]]. It is a high-level magical barrier that forced reality around oneself to ''obey'' your vision of the world. As a result, it turns reality within one's proximity into one's own mental landscape, allowing them to use their ultimate techniques. These are traditionally possessed by [[EldritchAbomination Ultimate Ones]] and high-level spirits.
* The Red Night in ''VisualNovel/ElevenEyes''.
* ''VideoGame/{{Diablo}}'''s Tristram Cathedral definitely qualifies. It begins with ''mere'' demon infested crypts, and only gets worse from there. It's revealed that [[RealityWarper Diablo's mere presence]] is warping the lower floors into Hell.
* ''VideoGame/FlightRising'' has the Starfall Isles, the homeland of the Arcane Flight. The ''first sentence'' of its encyclopedia page describes it as "the twisted, broken islands of the Arcanist and his scholars" and it only gets creepier from there. Every part of the region, including the wildlife, is being mutated by the magical energy flowing through the area, from the mountains which have curved inwards, the shoreline that is now a glowing forest, and the formerly-low island which keeps growing higher. There's also the [[ExtraEyes eight-eyed]] hummingbirds, levitating pill bugs, and owlets that turn pink when they hatch at the Observatory...
* ''VisualNovel/{{Demonbane}}'':
** The first game's final battle took place in a succession of these taken from the ''Literature/CthulhuMythos'' itself, as the sheer power being exchanged between Demonbane and Liber Legis causes "dimensional quakes" that randomly throw them all over time and space. They visit, in order: the chaotic darkness of the Void Beyond, the Great Library of Celeano, a ruined Yaddith of the far future, a living asteroid field, Prehistoric Earth, the Darkness of N'Kai, and in a couple of routes finally end up on the dead world of Yith.
** The Shining Trapezohedron is ''itself'' an EldritchLocation, and sealed within it are [[spoiler:all of the evil gods that Demonbane could not kill, trapped within one universe and screaming to get out. Slashing something with the Trapezohedron sends it to that universe... where that thing will be at the [[FateWorseThanDeath mercy of all those extremely angry, immortal, evil beings.]]]]
** The sequel's villain turns Arkham City into an EldritchLocation, as it becomes a patchwork of different time periods, urban city and wilderness melting into each other, buildings that are upside-down and right-side up and everything in between, and time moves faster, slower, backwards, or not at all in various places.
* VideoGame/TheEvilWithin: The entire setting. What starts out as an odyssey into a zombie-infested county gives way to SchizoTech, frequently shifting landscapes, and a slew of {{Eldritch Abomination}}s. It's revealed two-thirds into the story that [[spoiler:Sebastian is inside a hive-mind controlled by an extremely deranged sociopath. Which explains the monsters and why he's able to upgrade himself and his weapons by injecting himself with brain fluid - the monsters are the manifested nightmares of the various minds inside a simulation, and injecting himself with the defeated brains represents taking control of the simulation]].
* ''Videogame/{{Bloodborne}}'': It's never quite clear where the normal places end and the stranger places begin, considering some of the weird stuff your character starts to find once you start acquiring Insight, but a few places stand out:
** Byrgenwerth College's Lecture Building, and the college in general, which [[spoiler:seems to have been dragged off screaming into the Nightmare realm, and while it still more or less looks normal, it's warped inhabitants (which include its old students turned into slime monstrosities) will quickly tell you otherwise. Oh, and it somehow hid an entire, endless lake of shimmering white in the moon's reflection in a small pool. And killing the entity you find there will quickly drag the whole town into madness]].
** Yahar'Gul, [[spoiler:a town within a town. Somehow, the entities in charge of the whole MindScrew managed to hide a large, nightmarish citadel that resembles an earthbound R'lyeh, within the small town of Yarnham. Most specifically, in one of the cathedrals]].
** And, of course, the Nightmare Frontier, [[spoiler:the Great Ones' actual realm, crawling with stuff that will destroy your sanity in seconds, and housing the nightmares of several important players in the whole scheme, in particular one that acts as a freaking EldritchAbomination ''nursery'']].
** In a way, the Hunter's Dream and possibly [[spoiler:''every single thing after the blood transfusion at the start of the game'']] counts. It's simultaneously AllJustADream and a real, actual place you can go to. And sometimes, for extra MindScrew, you can access the dream part and the real part separately, leading to oddities such as finding the long-dead corpses of people you met minutes ago. And while they seemingly don't affect each other, as the game goes, you learn that it most definitely ''does''.
** There's also the Nightmare of Mensis, what is essentially a giant castle in the middle of a mental dreamscape that houses multiple EldritchAbomination s and appears to be the headquarters of the School of Mensis, a faction of the game's CorruptChurch that wishes to contact the ''other'' {{Eldritch Abomination}}s.
** ''The Old Hunters'' introduces the Hunter's Nightmare, a twisted version of Yharnam (which is already twisted as it is) populated by AxCrazy Hunters who have been damned to this realm. There's so much carnage to be found, that a river of blood cuts through the city from thousands of mutilated corpses that turn out to be NotQuiteDead once you come close to them. And at the end, after traveling through the clocktower of a BedlamHouse, you come to the source of it all: [[spoiler:[[Literature/TheShadowOverInnsmouth a small fishing hamlet]] populated by FishPeople that's been dragged into a nightmare dreamt by the unholy spawn of a dead Great One.]]
* ''VideoGame/TheBindingOfIsaac'':
** A couple of late-game stages could count, but none, more than the stage accessed after killing Isaac's Mom: [[WombLevel The Womb]]. Despite the title giving you an idea of where you are, it's best not to think about it too much beyond that, as it's accessed through a fleshy hole in the floor after beating Mom, is a giant labyrinth of enemy-filled rooms (including Mom's sentient, severed hands in ''[[UpdatedRerelease Rebirth]]'',) and the final stage boss is Mom's ''heart''. Not to mention that there's a literally doorway to ''Hell'' (well, Sheol, but still) in there. And then there's the Scarred Womb in ''Afterbirth'', a variation of the previous dungeon that looks like [[{{Gorn}} someone took a chainsaw to the inside.]]
** The "I AM ERROR Room," a deeply-hidden area that can only be reached by through either random teleportation or, as of ''Afterbirth'', causing a paradox[[labelnote:As in...]]Using a Blank Card (an activated item that replicates the card held by the player) on a ? Card (a card that replicates the activated item held by the player) or using Teleport 2.0 (teleports to the next unexplored room) after exploring every possible room in the map[[/labelnote]]. It has a glitchy floor along a black void, an equally-glitchy shopkeeper with a word balloon reading "I AM ERROR," a direct way to the next floor, and a number of rather random possible items, pickups, or other objects. It cannot be escaped by anything other than teleportation and little to no real in-story reason for its existence.
** The VeryDefinitelyFinalDungeon in ''Afterbirth +'': the Void. The entrance appears at random after major boss fights (always after one particular boss), and appears to be a twisted black portal similar to those that have been spawning enemies. The floor itself is made up of a random assortment of rooms from all other floors, and occasionally is subject to bursts of static that alter the landscape entirely. It's also the only floor in the game to have multiple boss rooms, as many as ''eight'', and only one of them contains the actual boss. Which one it is is entirely random. [[spoiler:The Void and its boss Delirium are a representation of Isaac's mind breaking down as he suffocates to death. If he dies here, the game over screen refers to dying "In some dying memory".]]
* The eponymous dungeons from the ''VideoGame/PokemonMysteryDungeon'' series are explained in-story as this. In ''[[VideoGame/PokemonMysteryDungeonExplorers Explorers]]'', they're said to be the result of temporal and spatial distortions.
* ''VideoGame/MinecraftStoryMode'': The Farlands. Unlike Minecraft, where it was simply a glitch, here it's basically the literal edge of the world and an area of chaos incarnate.
* ''VideoGame/{{DownWell}}'': The Abyss
* ''VideoGame/CorpseParty'' features Heavenly Host Elementary School. It's a haunted, [[GeniusLoci sentient]], [[AlienGeometries multi-layered]] dimension that consists of just the rundown school (it was originally in the real world, but after a series of murders it was torn down) and a never-ending expanse of trees with ceaseless rainfall. Anyone who is unfortunate to be caught in it can and most likely ''will'' die from either hunger or starvation, vengeful spirits, or any number of creative traps [[ChaosArchitecture the school]] will lure the player into, all if the person doesn't commit suicide. Even worse, a person can succumb to the [[TheCorruption darkening]] the school exerts, become insane and contribute to the problem by killing their fellow members. Let's not forget that anyone who dies in the school not only experiences the pain and agony of their death ''forever'', but is also ''[[RetGone erased]] from existence'' in the real world.
** Made even worse with the reveal of [[spoiler:the GroundhogDayLoop and time travel]]. Just as space and planes of existence are warped in this dimension, so is the concept of [[spoiler:time and parallel timelines. It's told that even if you tried to save someone who died before, they will just [[YouCantFightFate die a far more gruesome death]]. Sachiko has mentioned that Yoshiki has died a few times in other timelines, which leads to [[FridgeHorror the realization]] that ''every possible timeline was exhausted'' and Yui, Morishige, Mayu, and Seiko always ended up dying in the school so it was impossible to ever save them.]]
* The ''VideoGame/TalesSeries'' has had its great shares of bizarre locations over the course of its many games, but one area in ''VideoGame/TalesOfVesperia'' is noteworthy: [[spoiler:the parallel dimension where the Adephagos is imprisoned, a ''planet-sized'' squid that sucks aer dry]].
** There's also Tarqaron, a massive floating city that was converted into a weapon to counter [[spoiler:the Adephagos]]. The inside has warped pathways and structures built in every which way, and the party debates on just "what the hell were the ancients thinking when they built this?"
** ''VideoGame/TalesOfZestiria'' has [[spoiler:Artorius' Throne, the final dungeon]]. It's a sealed section of Glenwood that contains a massive palace suspended over an empty void, with collapsed and broken pathways surrounding it leading in every which way. The sky is blood red and the sun is black, and the entire area is engulfed in malevolence. [[spoiler:Makes sense, since a hellonized Maotelus was sealed in there.]]
* In ''VideoGame/ShadowWarrior2'', the in-game justification for the game's ProceduralGeneration is that Earth's landscape is constantly in flux.
* In the ''VideoGame/AlanWake'' games, Cauldron Lake is home to a RealityWarper EldritchAbomination called the Dark Presence, that desires to enter into our world fully as a MonsterFromBeyondTheVeil. In service of its goal, proximity to the lake grants creative humans the power of RewritingReality, though the beneficiaries of this power, protagonist included, tend to exploit it to defy the Presence's will once they glean its malign nature. Cauldron Lake itself is far more [[BiggerOnTheInside deep and vast]] than it appears, as a deep sea fishing trawler has somehow found a way to its suspiciously oceanic depths.
* Indie horror game ''Kholat'' gives us ''[[https://en.wikipedia.org/wiki/Kholat_Syakhl Kholat Syakhl]]'', a.k.a. the ''"Dead mountain"'', a real-life place in northern Urals, Russia.
* ''Franchise/{{Halo}}'':
** [[SubspaceOrHyperspace Slipstream space]] is a set of eleven non-visible and highly radioactive "nondimensions" that has markedly different laws of physics and "topology" from normal space, with FTL travel requiring you to enter it. It was known for making some people disappear without a trace when it was first put to use, and for the longest time it was nearly impossible for the [[TheFederation UNSC]] to accurately plot courses within it at distances smaller than a planetary system, though the [[ScaryDogmaticAliens Covenant]] and [[ThePrecursors Forerunners]] had already mastered that part. These effects worsen as jumps are made further inside a gravity well.
** Additionally, slipspace travel inherently causes all sorts of chronological and causal paradoxes which the universe then has to "reconcile"; if too much FTL travel is happening at once, than slipspace will automatically slow down or halt all traffic within it until reality has finished reconciling itself, with the strange part being that this "reconciliation" affects events both forwards and ''backwards'' in time. Due to humanity's inferior understanding of this phenomenon, two of their ships traveling through slipspace together to the same place will often either exit slipspace at different times or, if they do exit at the same time, experience time with slipspace differently (to the point where one ship's clock might be an entire week ahead of the other's).
** The dimension encountered in ''Literature/HaloFirstStrike'' when the ship containing the main characters enters slipspace using a [[MacGuffin Forerunner crystal]] takes the weirdness [[UpToEleven a step further]]. Energy Projectiles would randomly teleport or follow random trajectories while kinetic weapons were unaffected, with the crystal itself emitting massive amounts of radiation, causing some... [[TimeyWimeyBall contradictions in the recorded timelines]], and [[ArsonMurderAndJaywalking allowing ships to travel much greater distances across space than usual]].
** According to ''Literature/TheForerunnerSaga'', Forerunners discovered a large variety of strange alternate realms, including one composed solely of photons.
** The Domain appears to be depicted in such a way in ''VideoGame/Halo5Guardians'', though no physics defying effects occurred. This makes sense, given that it was created by [[spoiler:the Precursors, who themselves were {{Eldritch Abomination}}s]].
* The upcoming video game ''VideoGame/LittleNightmares'' takes place in a place only known as the Maw, filled with giant monsters and seems to be a cross between a hotel and a steampunk nightmare.
* The Room in ''VideoGame/{{OFF}}''. The rest of the game is [[WidgetSeries bizarre,]] but internally consistent and stable, [[spoiler:if undergoing some sudden changes after being purified]]. The Room is a small area that the Batter goes through multiple times spread across different "chapters" in reverse chronological order. The place changes in each iteration, there's one section where the camera inverts for no explainable reason (and remains upside-down until after solving a puzzle), a portion where you're taken to a mock-up of the main menu and pick three different "save files," a gigantic NPC that wants to play a game where you tell him numbers that appear in other sections, and it includes a segment that appears like a child's crayon drawings. It's implied that the whole thing is ''some'' sort of flashback from [[spoiler:its guardian, a sickly boy seen briefly after beating the first two bosses]].
* The planet Mira in ''VideoGame/XenobladeChroniclesX'' is an unusual planet which is acknowledged by the Earthlings that crash land on it. It features a lot of different climates in close proximity to each other and is crawling incredibly hostile {{Eldritch Abomination}}s, and those are the normal parts. The weird parts are the how the planet does not appear on any star map, the way it draws different alien species to it and prevents them from leaving, the way it acts as a UniversalTranslator for the aliens, and [[spoiler: how it can keep sentient androids running without a power source.]]
* In both games in the ''{{VideoGame/Fairune}}'', the Secret File, a room based around either a desktop file system, an old RPG or a roguelike populated by unkillable Space Invader-styled bit monsters, is this. [[spoiler: In 1, these seem to bleed into the final dungeon, and in 2, this could count for both Ashen World and it's underground, Sky Land.]]
* In ''VideoGame/MapleStory'', there is Ludibrium. On the surface, it's a toy world BuiltWithLEGO, but as you dive deep into its towers, the LEGO walls grow thin, eventually giving you view of some outer-space vista which shouldn't have been possible. It doesn't help that that deep in the towers, you'll see lots of ghosts.
* ''Videogame/HelloNeighbor'': The Neighbor's house, which becomes even more twisted and nonsensical with every update. As of Alpha 4, making it far enough into the house reveals rooms leading to nowhere, a fully-operating train supported by nothing, winding hallways, and all sorts of additional physics-defying hazards.
* In ''Videogame/Metro2033'' and ''Videogame/MetroLastLight'', the nuclear war that wiped out human civilization on the surface also broke the barrier between heaven, hell, and reality. Throughout the series, there's a number of locations where they all blend together, some of which are benevolent, and others that are antagonist either through malice or [[PleaseDontLeaveMe their own isolated misery]]:
** In ''2033'', you can find the ghost of a ''subway train'' that endlessly moves across the tunnel before being crushed in a tunnel collapse. On the actual wreckage, ghosts sit on their morning commute.
** In ''Last Light'', the passenger plane that crashed into Moscow is haunted, and those that enter the cockpit see the plane's last moments as the disables plane plows into an apartment block being blown apart in nuclear fire.
** In ''Last Light'', there is a tunnel on the surface haunted by the corpses of the untold millions that died. Their ghostly arms try to grab anyone stepping through because they are lonely and afraid.
** The weirdest is The River of Fate in ''Last Light'', a GeniusLoci where the dead can place phone calls, skeletons stare you down as you pass by, oh and you can [[TimeTravel view the past with your buddies]].
* In ''Warframe'' there is the Void, a dimension that can only be accessed through special keys. The area appears as a vast expanse of space and pure energy, with only the occasional abandoned Orokin tower [[spoiler: or the moon]] floating in it's space. It is the source of all energy that the Tenno use and it has close ties to the lost god-like race of the Orokin. Occasionally fissures in space leak void energy and allow the Orokin towers to use their mind controlling power extend their reach. [[spoiler: General Vor was even able to become a pure godlike being of energy with the use of a special void key.]]
* ''VideoGame/{{Sundered}}'' takes place in a series of impossibly vast caverns deep beneath the earth, [[ChaosArchitecture whose layout and architecture change every time the protagonist dies]]. The environments within the caverns start out relatively mundane, but become progressively more bizarre and disturbing the further down you go:
** The Valkyrie Encampment seems fairly normal at first, being a lush, jungle-like region with strange rock formations and seemingly endless waterfalls in the background. Then you realize that the only living things in this area are strange metallic plants that can grow through metal, and hideous man-sized arthropods with electrical powers that throw themselves at the player character in suicidal swarms. And the robots that guard the abandoned Valkyrie military base have tumorous organic growths coming out of themÖ
** The Holy City of the Eschaton is located in a rocky cavern where the walls are covered in carvings of bones and alien eyes, geysers of purple energy erupt from the ceiling, stone stairways float in midair, dark tentacles occasionally form within the shadows (sometimes forming walls to block your passage), and towering structures and statues loom in the background. And thatís not getting into the masked, robed, shrieking monstrosities that call this place homeÖ
** The Cathedral is a gargantuan edifice where AlienGeometries are in full effect: pieces of the structure float in an endless void, giant fists made of tentacles will lash out at the player from patches of dark fog (which can appear out of nowhere), and glowing fungi will spew clouds of poisonous spores if you get too close.
* ''VideoGame/SpecOpsTheLine'' takes place in a version of UsefulNotes/{{Dubai}} that is subtly this trope. The city looks mostly normal enough, putting aside the battle damage and corpses scattered everywhere, or Walker's hallucinations where the sky catches fire and hellspawn claw out of the ground. But it's also surrounded by an impossible, continuous sandstorm cutting it off from the outside world, and riven with great unexplained chasms. More important is the fact that a level usually starts with Walker and his team repelling or zip-lining down from one skyscraper to another, descending deeper into the war-torn city... and then when the next stage starts, they're back in a high place, and have to go down once more.
* ''VideoGame/DarkestDungeon'' has the titular dungeon, a combination of WombLevel and AlienGeometries. Being in it is so [[GoMadFromTheRevelation stressful]] that heroes who go in their once will refuse to return.

[[folder:Web Comics]]
* Ravenfell in ''Webcomic/OverlordOfRavenfell'' is a sentient fortress made of black crystal, created through mysterious means. Beneath it is a magically shifting maze full of traps and monsters.
* The Corpse in ''Webcomic/CogaNito'' is a blue-tinted forest studded with random chunks of orange machinery, so named because neither the trees are alive nor the machinery functioning.
* ''WebComic/{{Homestuck}}'':
** The Furthest Ring, a PlaceBeyondTime which is the home of the [[EldritchAbomination Horrorterrors]], the Green Sun (a star with the mass of two universes, which breaks several laws of physics), and the afterlife (which exists as a series of Dream Bubbles). It is said that if one were to draw an accurate map of the place, the result would be a page completely and uniformly covered in black. Time and space behave in incomprehensible ways in the Furthest Ring, and both become less reliable the longer you stay (or the further you go). For example, when Dave and Rose try to fly out to the Green Sun, [[spoiler:they end up arriving in the distant past]].
** Dream Bubbles themselves may count, as within them the conventional laws of time and space don't apply, as one can warp from memory to memory, effectively traveling forward and back in time and anywhere in space. Locations can even converge in such a way that they're a mis-match of memories of the various dreamers/dead people. For example, in one there was a mixture between Jade's island, Kanaya's home, a ruin Aradia was exploring, and some other elements.
* ''Webcomic/SluggyFreelance'' has plenty. The alternative dimensions vary from almost identical to the "normal" one to as bizarre as you like. One example: The Never is a hellish world where spirits become solid and living creatures become even more so than usual. Other Eldritch Locations can be found without even travelling between dimensions. Each dimension is surrounded by Timeless Space, where time is only carried by objects and creatures and will eventually run out for each of them, freezing it in place. The two [[TomeOfEldritchLore Tomes of Eldritch Lore]] ''Book of E-Ville'' and ''Wayang Kulit'' each contain or give access into a different kind of symbolic nightmarish world that builds itself around the thoughts of an entering character.
* The Palm Tree Ghost's realm is turning out to be [[http://danielscreations.com/ola/comics/ep0296.html more and more this way]] in ''Webcomic/OurLittleAdventure''.
* Webcomic/TalesOfTheQuestor has the Unseleighe castle of Princeling Dolan in Tir Na Nogh. Simply navigating the halls can make you arf your cookies.
* In ''Webcomic/MetroidThirdDerivative'', Planet Nemesis as named by Samus. She identified it at the source of all Phazon with the core of the planet being pure Phazon while the atmosphere and various landmasses that float above it having heavy concentrations of Phazon. A ring of Phazon meteors circle the planet destined to be thrown into space and affect other planets. Lifeforms not resistant to Phazon will die quickly on Nemesis.
* The forest in ''Webcomic/LucidSpring'' transforms into this whenever Viktor and Pacem's [[http://lucidspring.thecomicseries.com/comics/36 hallucinations]] [[http://lucidspring.thecomicseries.com/comics/37 are seen.]] The world takes on a red tint, Viktor and Pacem have wounds they don't really have, and trees ''bleed.''
* Often PlayedForLaughs in ''Webcomic/{{Nedroid}}'', including [[http://nedroid.com/2010/07/ask-your-travel-agent/ the Magma Zone]] and in [[http://nedroid.com/2009/10/fall-foliage/ this]] strip.
-->'''Reginald:''' Autumn is [[DissonantSerenity especially beautiful]] here in the Nightmare Zone.

* ''Webcomic/ZebraGirl'': Sandra's house. It began to change when Sandra transformed into a demon, with shadows becoming darker and bigger, and decided to have a growth spurt on its own while Sandra was away.

[[folder:Web Original]]
* Many Wiki/{{SCP|Foundation}}s are {{Eldritch Location}}s. Some of them also qualify as {{Eldritch Abomination}}s since they are ''[[GeniusLoci alive]]''. There's also [[http://scp-wiki.wikidot.com/scp-093 the "Red Sea Object"]], which takes people into an alternate universe where [[spoiler:"a god-like being of unknown origin" instigated a massive holy war hundreds of years ago, with apocalyptic results, and now giant, immortal UncannyValley monsters roam the land, absorbing anyone who catches their attention]].
** According to [[http://www.scp-wiki.net/exploratory-mission-354-alpha this tale]], [[http://www.scp-wiki.net/scp-354 SCP-354]] leads to a world like this. Days last 43 1/2 hours, the sun is bright red, and the laws of physics don't seem to be consistent. Compasses shift daily and liquid water exists alongside liquid carbon dioxide. And there's also [[spoiler: the heavy implication that the world can erase people from existence.]]
* ''WebAnimation/HomestarRunner'':
** [[http://www.homestarrunner.com/sbemail174.html Sweet Puttin' Cakes]], a miniature golf course "every bit as messed up as the cartoon on which it's based." Residents of Free Country, USA find themselves inexplicably teleported there simply by desiring to play miniature golf. The first hole is the [[VisualPun "worm"hole]], the 18th hole has par infinity, and the only way to leave is to will yourself back to reality. When Strong Bad returns, he remarks that his mouth "[[TastesLikePurple tastes like backwards]]."
** We could go ahead and classify the Sweet Cuppin' Cakes world (which is apparently a real location) as an Eldritch Location. Just think of the inhabitants! A Strong Bad with a keyboard head, a black-and-white-talking wheelchair, a talking worm in a hole that appears to be able to warp from place to place. There's also the fact that characters can come from nowhere and that everything appears to be able to utilize hammerspace.
* ''Roleplay/RubyQuest'':
** Cold Storage.
** Much of the whole facility, really. Especially the brig, with that growing dark pit and half of its gravity reversed.
* Brian's house in ''WebVideo/MarbleHornets'' became this, thanks to [[Franchise/TheSlenderManMythos a certain someone]]. It doesn't fully follow the laws of reality and is connected to a burnt-out, industrial-looking building that is laden with even more horror.
* Sarah Waite's (yes, the last name is meaningful) dorm room at [[SuperheroSchool Whateley Academy]] in the Literature/WhateleyUniverse. It's even ''called'' the Lovecraft Room.
* WebVideo/NyxCrossing, a mysterious area that centers around a section of railroad track. According to the natives, "There is no distance," and there is a mysterious monster that stalks the characters.
* The [[http://bogleech.tumblr.com/post/74701719961/i-know-that-the-noisy-tenant-universe-the-one-where Noisy Tenant Creepypasta mythos]] is very much set in this this, given that in the core premise is that people suddenly wake up, out of nowhere, in the titular building, an endless place where space [[spoiler: and time, if the ending to Dr. Phage's Hospital is any indication]] doesn't work the same as in our reality and where there's been no exit shown in-setting.
** The place itself can be described as what would happen if Franchise/SilentHill were designed by Creator/SidAndMartyKrofftProductions , with whimsical inhabitants (An anthropomorphic hamburger chef made of rotting meat and a man-sized bacteriopage doctor with glasses and a bow-tie being the most prominent) who do horrible; horrible things to the people stuck in their realms...
** And, as a bonus, [[Website/{{Bogleech}} the creator]] has said that it's not anything as banal as another planet or another dimension, but rather something humankind has no context whatsoever for. He compared trying to explain the reason why it exists to explaining to a Pilgrim the concept of a WebAnimation/YouTubePoop without explaining computers, videos or electricity.
* ''Franchise/TheFearMythos'' has the Empty City: a possibly [[EldritchAbomination living]] city located in an alternate dimension. The city is ''huge'', changes every time you turn a corner, and is completely devoid of all souls.
* In ''Literature/TheDionaeaHouse'', the titular "dionaea house".
* Parodied in LetsPlay/ChipCheezum's LetsPlay of ''VideoGame/FiftyCentBloodOnTheSand'' with the "Fiddy Zone", a glitch where background textures fail to load during a [[ActionCommands Counter Kill]], leaving Fiddy and his opponent in a void covered by film grain.
%%* Wherever the hell it is that the WebAnimation/HappyTreeFriends universe takes place in.
* in ''Webcomic/DemonThesis'', the four main characters attend a small liberal arts college in Canada, when a [[ManipulativeBastard manipulative entity]] from another dimension begins altering reality. Only afterward do the main characters learn that their school was originally founded by an occultist who knew that the location was a place where our dimension was unusually close to and could interact with other dimensions. Said occultist intended the university to inform about the dangers of this and form a line of defense against threats, but over time the school transformed into a fairly normal university and most occult/supernatural elements have been discarded.
* ''WebVideo/CollegeSaga'' has the Cursed Structure (i.e. Babson College's Fountain of Flags). As long as it exists, mankind will continue eating vegetables.
* Prominently featured in [[http://wanderers-library.wikidot.com/the-tomb-war The Tomb War]] from ''Wiki/TheWanderersLibrary''.
* ''Literature/TheSickLand'' revolves around such a location. The titular Sick Land is a massive patch of land where strange plant life grows; people and animals that stay there for too long suffered bizarre, incurable, and fatal mutations and sickness. [[spoiler: Later it's revealed to be ''spreading'' at a slow rate, corrupting the land around it.]]
* ''Podcast/WelcomeToNightVale'', where everything paranormal is true.
* The Fineum Cuniculum from Wiki/TheWorldbuildProject probably qualifies. No one knows how it got there? Check. Mysterious engraving all down the walls of a three kilometer tunnel? Check. People randomly disappearing? Check.
* In ''Podcast/AliceIsntDead'', a long haul trucker {{Narrator}} keeps encountering paranormal places in the course of her work, from an EvilTowerOfOminousness looming in the distance to Charlatan, a traveling VanishingVillage trapped in a GroundhogDayLoop that repeatedly violates the laws of physics in increasingly disturbing ways every time she passes through.
* ''WebOriginal/ProtectorsOfThePlotContinuum'' has Headquarters, an unimaginably huge building located in the space between worlds that the PPC calls home. It's constructed from {{metafiction}}al materials like {{Plot Hole}}s and "concrit" ([[{{Pun}} concrete made from constructive criticism]]) and a portal to it exists in one specific location in each world of TheMultiverse, usually an extremely innocuous one nobody would check if they weren't specifically looking for it. Its most famous feature is that, as a defense against MarySue attacks, it's impossible to ''intentionally'' find your destination within it; PPC agents are well trained to "switch off" their minds whilst trying to get from one part of the building to another, something the simple brains of Sues are incapable of. A RunningGag in the stories is that it supposedly has a pool, but nobody, whether intentionally or not, has ever been able to find it.
* ''Literature/GreenAntarctica'': The glacier at the center of the continent is seen as one by the Tsalal, one so evil that they refuse to give it a name. While their entire culture [[SnowMeansDeath fears the color white]], it goes beyond just that. The glacier is the size of a country and half a mile thick. The dry, chilled air above it is unnaturally lit by the sun and carries sounds differently, giving it the feeling that reality is warped by its very presence. The entire thing moans and creaks as fissures open up and water erupts outward. Its edges expand and retreat like the pseudopods of a vast amoeba. There are times when the winds will trigger a sudden torrent of frigid air that splashes outward and kills everything in its path. The Tsalal cultures alternatively view it as the source of all death and suffering, hell, the abode of the gods, or even a sleeping god itself. What they can all agree on is that, when it awakens, it will bring about the end of all worlds.
[[/folder]]

[[folder:WebVideo]]
* The second chapter of [[WebVideo/MLPAnalysis Dr. Wolf's]] OriginEpisode takes place in such a place that takes the form of a library in the middle of a vast desert. Time doesn't move in the library, as Wolf doesn't age or require food, water, or rest the entire time he's there. The structure goes on forever in any direction, smells do not grow stronger or weaker anywhere or at any time, and Wolf always sensed a feeling of intrusion, as if the library sensed he and his master didn't belong and desired to expell or assimilate them.
* ''WebVideo/CarmillaTheSeries'' has the library. While more or less the entire campus is [[ExtranormalInstitute weird]], the library is above and beyond anything there, described as a sentient Escher painting with shelves and a force to be reckoned with against even the most powerful beings of the series. It stuck someone into a computer system before computers were even invented, has portals [[NotHyperbole literally]] everywhere, and a personality that ranges from [[PokeThePoodle comedically annoying]] to outright terrifying when enraged.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/JackieChanAdventures'' has the [[PrisonDimension Netherworld]], a dimension that the [[OurDemonsAreDifferent Demon]] [[EvilSorcerer Sorcerers]] were banished to by the [[Myth/ChineseMythology Eight Immortals]]. The Netherworld is a seemingly infinite void filled with floating rocks, which condemns [[SorcerousOverlord the]] [[DemonLordsAndArchdevils Demons]] to an eternity of boredom.
* The Spirit World in ''WesternAnimation/AvatarTheLastAirbender''. Shown in more detail in ''WesternAnimation/TheLegendOfKorra'', as we see such thing as [[FisherKing the terrain and inhabitants being affected by the emotions of humans inside of it]], [[GravityScrew gravity not going in any particular direction]], and [[AlienGeometry conventional concepts of location and distance being violated.]]
* The Ghost Zone in ''WesternAnimation/DannyPhantom'' which serves as an "opposite" dimension to Earth. Home to ghosts, it's a massive world where its sky is a swirl of eerie green and black. Surrounding the majority of the GZ are (usually small) floating lands--it's rare to find giant land masses since ghosts don't really need to walk--and multiple floating doors that lead to various ghostly realms, all unique, surreal, and different based on how it fits the ghostly inhabitants.
** Those large landmasses include a giant prison, an island that's the home base of an EgomaniacHunter, and the ''temple of Pandora''.
* ''WesternAnimation/SouthPark'':
** The evil half of Imaginationland. They never allow anyone or anything good to cross into their territory or else they'll be killed. Otherwise, they have no interest in war, [[PretextForWar until the terrorists attacked both halves of Imaginationland and pinned attacks on the Evil territory on the Good Imaginary Characters.]]
** The Dark Oblivion, also known as the Sunken City of R'lyeh in Coon 2 literally personifies this trope, as it is supposed to be Cthulhu's home plane.
* Possibly the emperor's palace in ''WesternAnimation/XiaolinShowdown'' as it is one of the only places where, if a Showdown is declared, the participant's clothing does ''not'' change. While this could be written off as for sake of plot (Kimiko's formal but awkward kimono made it more of a challenge for her to overcome) [[FridgeLogic it makes sense]] if you consider the societal rules of etiquette of such a place; the palace emits a spiritual counter spell to prevent other sources of magic to break such taboos.
* Although it's much more light-hearted than most, Wacky Land in ''WesternAnimation/TinyToonAdventures'' probably qualifies. The original Wacky Land, however, featured in at least one Looney Toon short and its color remake, varies from merely inexplicable to subtly menacing in its bizarreness.
* The Web in ''WesternAnimation/ReBoot''. Dark and organic looking in comparison to The Net's bright technological look.
* ''WesternAnimation/SpongeBobSquarePants'' gives us "The Fly of Despair" from "Shangheid", a dimension that only the Flying Dutchman and Squidward know about which is nothing but a dark tunnel of surreal, demonic imagery.
* ''WesternAnimation/TheRealGhostbusters''[=/=]''WesternAnimation/ExtremeGhostbusters'' made regular use of these. From the Bogeyman's home dimension to a sneak peek at the end of the world to a ghostly pirate TV station, the series enjoyed dropping the Ghostbusters in places where physics didn't work right and the architect expected the residents to be capable of phasing through walls. Some examples:
** New York in general seems to be this in their universe, it is constantly attacked by all sorts of spirits, monsters, demons, LegionsOfHell and interidmensional creatures.
** The Containment Unity evolved into this after a while. How exactly become BiggerOnTheInside is never explained but it seems to be its own immense PocketDimension, very similar in look to the Netherworld.
** The Neterworld which is basically AnotherDimension from where ghosts are original. Winstons describes it as a place full of spirits, demons and souls of people that couldnít reach other realms. The look of it varies from episode to episode (justified as itís said by Ray that it has the size of our universe) but itís mostly shown as a huge wasteland with floating boulders and mist.
** The cabinet dimension: a dimension connected to our world from a magicians cabinet is pretty much a [[FireAndBrimstoneHell hell dimension with boiling lava and snakes raining from the sky]].
* ''WesternAnimation/TheSimpsons'':
** Springfield could very well count at this point. One look at the JustForFun/SeparateSimpsonsGeographyThing page should tell you all you need to know.
** The occasionally mentioned "Springfield Mystery Spot". It's unclear if Ozzy Smith was ever seen again
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** [[PlayingWithATrope It plays with this]] via the Everfree Forest. While home to an assortment of beastly critters -- like manticores, sea serpents and cockatrices -- and weather that is consistently "dark and stormy", the ponies also regard it as horrific and unnatural because ''everything there takes care of itself''. The plants grow on their own, the animals don't need to be looked after, the weather runs without help... it's '''surreal'''! ([[PaintingTheFrostOnWindows From their point of view, anyway.]])
** Played straight in the season 2 premiere with Discord's hedge maze, which could be best described as [[Creator/MCEscher Escherian]] shrubbery. Not really a surprise when the architect is a [[RealityWarper Reality Warping]] spirit of chaos. In the second episode he turns all of Ponyville into this, [[WorldGoneMad and drives its inhabitants insane for good measure]].
** We get to follow Discord home in season five. It's a PocketDimension that does ''not'' disappoint in terms of WorldGoneMad. As such... [[UnstoppableMailman the mail is sometimes delivered *slightly* late]].
** In ''WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames'', the Twilight Sparkle who originates from the human world briefly stumbles into [[spoiler:the pony world]] [[GoMadFromTheRevelation and returns completely insane]], hinting that to regular humans, [[spoiler:the pony world itself]] is an Eldritch location.
* ''WesternAnimation/{{Superjail}}'' is full of these, especially within Superjail itself, but the [[TimePolice Time Court and Time Jail]] in "Time Police" take the cake. Considering it's a place where all living beings from all corners of the universe and time work or are tried and imprisoned, this is to be expected.
* A ''WesternAnimation/FamilyGuy'' skit shows Peter going into the 'beyond' section of 'Bed, Bath, and Beyond' which is a black void filled with various floating formulas and the like...and the coffee mugs he was looking for.
* [[WesternAnimation/InvaderZim A room with a moose. A dimension of pure dookie.]]
* ''WesternAnimation/AdventureTime'':
** The Nightosphere, home loads of creepy demons and is essentially Hell.
** The rest of the land of Ooo is pretty weird too. There's a kingdom ''made of candy'' that is ''populated by candy''.
* ''WesternAnimation/CourageTheCowardlyDog'': Nowhere, Kansas. It looks like a desert wasteland where strange monsters show up for no real reason at all. [[StealthPun And the main cast lives in the middle of it.]]
* ''WesternAnimation/RegularShow'' the park is constantly swarming with weird people, bizarre creatures, and EldritchAbomination that appear by ripping of the very fabric of reality.
* ''WesternAnimation/GravityFalls'' is a magnet for all sorts of bizarre people, creatures and entities, including a clan of macho minotaurs, a bear with more than a dozen heads, and a walking mass of rejected Halloween candy. There's also a LostWorld in the caves beneath the town, complete with still-living dinosaurs [[HumanPopsicle encased in tree-sap]].
** [[spoiler: There's also the Nightmare Realm. A decaying dimension that is the home of several interdimensional criminals and nightmares, all of which are leaked into the titular town in Weirdmagedon by Bill Cipher.]]
* Elmore from WesternAnimation/TheAmazingWorldOfGumball definitely counts, considering [[spoiler: the entire plot of an episode involves a black void where the town dumps all its mistakes.]] In fact, the aforementioned [[spoiler: black void]] counts, what with [[spoiler: its alien geometry, and how the current BigBad was permanently scarred upon exit.]]
* Many locations in ''WesternAnimation/StevenUniverse'' are peculiar or exceptional (such as the pyramid from ''Serious Steven'' or the Lunar Sea Spire in ''Cheeseburger Backpack''), but the inside of the Gem Temple easily takes the cake as one of the weirder and more frequently seen locations. The main door opens up to different locations depending on who operates it, it has multiple organs including a colossal pulsating heart, and there are corridors that twist on themselves while still maintaining a nebulous sense of gravity... to say nothing of the personalized rooms each of the gems have:
** Pearl's room is a series of freestanding waterfalls which she [[WalkOnWater stands atop]] and keeps objects inside the water. It also features what looks to be a starry sky overhead, completely ignoring the fact that this is supposed to be indoors. Further down, the waterfalls flow sideways and even upwards.
** Amethyst's room is a section of shallow purple coastline below Pearl's, littered with an assortment of objects including a palm tree and piles of gold coins. Huge crystals grow out of the walls and floor. Said coast is littered with puddles where, if you submerge yourself on one side, you emerge from the ceiling or floor of a different room.
** Garnet's room is a low, circular area floored in stone. Unlike the others it actually seems like it could feasibly be inside, but the ''veins'' of the temple feed into the walls on all sides and the ceiling is filled with bubbled gems. There's also a pit of exposed lava in the center [[KillItWithFire which sees occasional use]].
** Rose's room is a huge expanse of sparkling pink clouds that has this little thing of recreating anything its occupants ask for out of said clouds. It also operates like a computer simulation and [[OminousVisualGlitch crashes]] if asked to create anything too grandiose.
*** There's also the inside of Lion's mane, a PocketDimension that could be best described as an airless, Pink version of The Moon from Majora's Mask. It contains several things that were important to Rose, such as one of Greg's t-shirts, her sword, a video for Steven, and, formerly, [[spoiler: a bubble containing Bismuth's gem.]]
** Sardonyx's room, a black expanse that looks similar to a talk show room complete with an unseen audience, which Sardonyx can manipulate however she wants. It also only exists when Pearl and Garnet are fused as Sardonyx.
* In an episode of ''WesternAnimation/TheNewMrPeabodyAndShermanShow'' the show gets consumed by a black hole. Mr. Peabody keeps hosting from inside, a bizarre space where the rules of physics do not apply and anyone can become anything.
* In ''WesternAnimation/InfinityTrain'', a girl named Tulip is stuck on a seemingly endless train in the middle of nowhere. Tulip has spent a week traversing the cars to no avail. The train seemingly has no end, it possesses creatures which defy logic, and the cars themselves have properties which don't fit their external design. The train does have a front end, as seen in the opening, but would have to be impossibly long for Tulip to have spent as long as she has moving through cars.

[[folder:Real Life]]
* The [[EldritchLocation page quote]] from ''Zauriel'', above, well describes the [[http://en.wikipedia.org/wiki/Photosphere surface of the sun]]. The innards of a star, the depths of a [[http://en.wikipedia.org/wiki/Gas_giant gas giant]] and the vacuum of [[http://en.wikipedia.org/wiki/Outer_space deep space]] all feature mechanical properties that are incomprehensibly alien in comparison to the natural laws as we know them. Small and frail is the magical bubble in which we live and thrive.
** We can do better than that: Black holes! Also, Calabi-Yau space, the universe before the Big Bang, and pretty much anything beyond the universe. And the inside of an atom. Actually, the modern understanding of physics pretty much [[ThisIsYourPremiseOnDrugs requires a lot of drugs to understand]].
** Some of these have since put to contest - for example, the quantum physics as we know it doesn't allow an absolute singularity to form, even though General Relativity does, which may mean that no "true" black holes exist, whereas other theories challenge the idea of the Big Bang as the start of the Universe - it has already been all but disproved in the form it's being taught in schoolbooks, but the event's exact nature still eludes the scientists, and there are multiple conflicting theories without enough evidence to pick one over the others.
** Understanding the singularity that was the entire universe could require a higher level of maths than we have so far. [[http://io9.com/?_escaped_fragment_=5773158/what-really-happened-right-after-the-big-bang#!5773158/what-really-happened-right-after-the-big-bang Considering that the physics at the literal instant after the expansion began were so much different than what's in the universe now, it's not hard to conceive that.]]
** Black holes aside, neutron stars also qualify. They are so far removed from our everyday life that they are basically incomprehensible to the human mind. Their surface is so smooth that a mirror is a mountain range in comparison, and so dense and hard that a diamond is like the vacuum of outer space in comparison. The surface gravity is so strong that it very visibly bends light, and any matter will get crushed into it so hard that even its constituent particles will break and fuse into neutrons. The whole star has a mass of tens of suns and can rotate even at over a thousand revolutions per second. Because of this incomprehensibly rapid rotation speed, the star is actually a spheroid instead of a pure sphere, regardless of its density: That's how fast it rotates. And when the rotation slows down over time due to loss of energy, an unstoppable force (gravity) will acting on an immovable object (the surface of the star)... When the rotation speed has slowed down enough, the surface will give way and the ''entire'' star will restructure as a slightly less elongated spheroid... an event that's so immensely powerful that it emits an incredible amount of energy to outer space as a big flash.
** The spacetime inside of a black hole is one of the most alien regions we have yet speculated. While black holes do not "suck" things in, past the event horizon the gravity from the singularity has distorted space time so much that all paths lead deeper into the black hole. This is why light cannot escape a black hole, not because the escape velocity would exceed the speed of light, but because there is literally no path out, only deeper.
* Singularities in general are this in whatever system they might manifest in. Simply, a "singularity" is an instance in a system where the normal rules of the system are inapplicable.
* Planets with high gravity or atmospheric pressure can make for some extremely odd locations. There is one exoplanet for example that the scientists believe to be covered in boiling hot ice due to such conditions.
* Our planet itself has one in the form of the ocean, especially deep down in the trenches.
** Creatures born without what we would see as vital to living, pillars of sulfur belch toxic superheated smoke, the pressure so intense even thick steel can be crushed easily; and that's just scraping the surface of what's down there. Supposedly, there's more undiscovered species down there than there are extinct species.
** [[http://en.wikipedia.org/wiki/Undersea_lake Brine lakes]]. They are, for all intents and purposes, lakes under the ocean, complete with a shoreline. Even more [[MindScrew mind screw-y]], the density of the brine lake's surface means that any submarine that visits it can "float" on top of the denser brine lake surface. While already underwater. That's right, scientists found [[WesternAnimation/SpongeBobSquarePants Goo Lagoon]]!
** There is also the phenomenon of [[https://en.wikipedia.org/wiki/Deep-sea_gigantism deep-sea gigantism]], as well. For unknown reasons, with theories ranging from greater energy conservation, to protection against the pressure and cold of the deep sea, several animal species grow several times larger than relative species in other parts of the ocean. Such creatures include [[https://en.wikipedia.org/wiki/Giant_isopod giant isopods]], ''[[https://en.wikipedia.org/wiki/Alicella Alicella]]'', [[https://en.wikipedia.org/wiki/Japanese_spider_crab the Japanese spider crab]] and various forms of giant mollusk, such as the [[https://en.wikipedia.org/wiki/Seven-arm_octopus seven-arm octopus]] and the [[https://en.wikipedia.org/wiki/Giant_squid giant squid]]. While many of these creatures are more or less larger versions of animals found elsewhere, it only adds to the strangeness of the abyssal ocean.
* Conceptualizing how the world appears to animals with radically-different BizarreAlienSenses -- echolocation, electroreception, vibratory sense, etc -- can reveal how different even an ordinary room must seem to them.
** Any species that can perceive radio signals as sound or sight would be driven blind or deaf immediately, if not completely insane.
** Imagine getting trapped in a strange dimension where dozens or even hundreds of suns blink in and out seemingly at random, populated by [[HumansAreCthulhu titanic monsters that will brutally crush you for merely annoying them with your existence whenever you stop to take a rest.]] This could very well be how a flying insect experiences a building they have flown into.
** The universe of the fairy fly. Air is an all-encompassing jelly that it has to grab onto to fly.
* Antarctica. So many things make this place this. From four month summers and four month winters, places that look similar to Mars, hurricane winds that constantly happen with category 5 winds happening once every winter, green lights constantly appearing, it is one weird place.
** And that is not even touching on what may be preserved under the ice...
* The [[https://en.wikipedia.org/wiki/Darvaza_gas_crater Darvaza gas crater.]] Geologists broke through to a huge gas cavern, decided it was too dangerous, set it on fire, and left it burning for over ''40 years.'' It's literally called the ''gate to hell.''

----

to:

* ''TabletopGame/DungeonsAndDragons'' has a cosmology that gets weirder the further you venture from the Prime Material Plane. The transitive planes, the Astral and Ethereal Planes, are familiar enough to those who have heard of out-of-body experiences, and the Plane of Shadow is a morose DarkWorld based on the Material Plane. The Inner Planes are each dominated by one of the four classical elements, while the Outer Planes are impossibly beautiful in the case of the Upper Planes and utterly horrifying in the case of the Lower Planes. In any case, each plane in the Great Wheel has its own internal logic to it, even if in the case of Limbo that logic is "chaos." And then ''outside'' of this cosmology, perhaps on the very edge of reality, is the Far Realm. The only identifiable trait of the Far Realm is that none of it is identifiable, or even quantifiable in any way, shape or form. Simply entering it threatens a visitor's sanity - characters may sprout eyes on their palms (but not really), relive a hundred lifetimes in which their parents were Far Realm wights, or backwards speaking begin... Unsurprisingly, the Far Realm is based on the works and mythos of H.P. Lovecraft.
* The D&D settings of TabletopGame/{{Ravenloft}}, TabletopGame/{{Planescape}}, and (by way of Art Major Astrophysics) TabletopGame/{{Spelljammer}} each qualify as an EldritchLocation by their very nature.
* Terra Incognitae in ''TabletopGame/{{Scion}}'' are all the mysterious islands and lost worlds described in mythology. You can't get to them unless you yourself are mythological (i.e., have a Legend score).
** In addition, there are the Underworlds and Overworlds of the various pantheons, which operate by the rules the Gods set; the [[GeniusLoci Greater Titans]], living embodiments of a particular element such as Light, Water, Sky, Chaos, Time, etc;, and in first edition, Touchstones, the archetypal locations humanity has given meaning to (the Great Henge, the Colossus, the Dark Woods, etc.), which can be accessed through their mundane analogues. Again, you need to be mythological to get to these places, and in some cases you need to be of a certain Legend score or above to enter.
* Bardos in ''TabletopGame/GeniusTheTransgression'' are places that were once thought or believed to exist, [[ScienceMarchesOn then proved not to]], or were hoped to exist but [[IWantMyJetpack never came to pass]]. You can still travel to them if you know where to go (or stumble into them). They range from [[UsefulNotes/{{Mars}} the Martian Empire]] and [[{{Dystopia}} Tsoska]] to the Hollow Earth (recently taken over by [[StupidJetpackHitler Nazi mad scientists]]) and [[{{Cyberspace}} The Grid]].
* ''TabletopGame/ChangelingTheLost'' gives up a couple of examples.
** First is [[TheLostWoods the Hedge]], the mysterious otherspace between Earth and Faerie. Not only does it seem to map roughly to Earth in size, but it could technically be considered four-dimensional, as there's ''always'' going to be a direction that's just "towards Faerie."
** Faerie (Arcadia, Alfheim, et al.) itself is another example. A place formed purely of the magic of dreamstuff, where reality only exists because everything in it has agreed to exist and interact. This is completely disregarding the fact that many of the Realms in Arcadia are [[spoiler: [[GeniusLoci The True Fae themselves]]]].
* ''TabletopGame/BeastThePrimordial'' has the Lairs, individual to each Beast, an otherspace that is reflective of their own power (the higher their PowerStat goes, the more chambers it gains) that can be entered through any doorway.
* Pretty much everywhere outside of Illusion in TabletopGame/{{Kult}}. Weird geoscapes are the least of your worries. Gaia is the primal world where even the ''earth'' can get hungry and swallow people, Metropolis is a city filled with lunatics and Inferno is a classic {{hell}}.
* The Mad City of TabletopGame/DontRestYourHead is pretty much made of this trope.
* ''TabletopGame/{{Exalted}}'':
** The Wyld, in which reality as we know it pretty much stops working. Divided into the Bordermarches, the closest regions to normal reality, which are only mildly weird, the Middlemarches, where the laws of physics cease to be reliable and movement and distance are [[TheoryOfNarrativeCausality based more around narrative conventions than concrete measurements]], the Deep Wyld, where reality is officially [[RealityIsOutToLunch Out To Lunch]], and the Pure Chaos, which isn't so much a location as it is the unshaped, incoherent chaos outside of the universe.
** And then there are the Shadowlands, sites of past atrocities and mass murder where the border between Creation and the Underworld is just a bit thinner. Regaining Essence is hampered (unless you're a creature of the Underworld, in which case it picks up by comparison), ghosts can get around more easily, and improperly buried bodies tend to rise as zombies.
** Several of the Primordials/Yozis [[GeniusLoci are this]] as well. Things like the local geography, physical laws, and even time flow are often at the whims of the Titan that is the world. The most notable are Malfeas (the Demon King/City whose body acts as the prison of his fellows, and consists of multiple layers that constantly change shape and correspondence, and all inexplicably have the green sun of Hell right above them), Cecylene (the Endless Desert who is accessible from every layer of Malfeas and always takes ''exactly'' five days to cross) and Autochthon (who needed to deliberately modify his world body to make it habitable; the deeper parts of it show the reason for this).
** There are even a few places in Creation that work like this. One is the Well of Udr, overseen by [[NamesToRunAwayFromReallyFast the Dowager of the Irreverent Vulgate in Unrent Veils]]. It's a nexus of all possible dimensions where the strata of potential worlds collide and crash against one another, occasionally disgorging impossibilities. It's very tricky to get anywhere within its vicinity and hold onto your marbles, let alone stare into it. It's from here that the Dowager retrieved [[TheEndOfTheWorldAsWeKnowIt the Great Contagion]].
** The Elemental Poles, too, each of which is an unending font of elemental power. The trees at the Elemental Pole of Wood are infinitely tall.
* The Umbra from the ''TabletopGame/OldWorldOfDarkness'' folds in itself any sort of alternative reality and other states of being. And one has to step ''sideways'' to reach it. Sideways to reality as a whole. Furthermore, different places in the Umbra have their own laws, and the further one gets from Earth, the weirder and more hostile the worlds become, until the Deep Umbra is reached. Things are just plain ''wrong'' there. And very, ''very'' inhospitable for almost any type of earth-like life.
** And then there's the [[NamesToRunAwayFromReallyFast Black Spiral]], located in Malfeas (the Shenti of the Wyrm). Depending on [[CanonDiscontinuity which game in the cobbled together setting]] you happen to be operating in, the Black Spiral is either in [[TabletopGame/WerewolfTheApocalypse the Deep Umbra]], [[TabletopGame/ChangelingTheDreaming the Dark Dreaming]], [[TabletopGame/WraithTheOblivion the center of the Maelstrom]], or is either a convergence or a place that has doorways to all three. Put simply, it's Hell, but of course it's not that simple and entire books have been dedicated to describing, expanding, contradicting and redefining what the Black Spiral actually is. ''TabletopGame/WerewolfTheApocalypse'' describes it as the tormented mind of the Wyrm itself. There are even allusions that it is the dessicated husk of ancient Malfeas from ''TabletopGame/{{Exalted}}''. It breaks, reshapes and fundamentally corrupts anyone unlucky enough to find themselves there, and we're talking mentally, physically and spiritually, all at once. It is the home, seat of power, [[GeniusLoci dying body]] and [[AndIMustScream prison]] of the Wyrm, the primordial force of entropy in the setting's universe. One tribe of werewolves are called the [[NamesToRunAwayFromReallyFast Black Spiral Dancers]]. Guess what they do for an initiation rite?
* The Shadow Realm of the ''TabletopGame/NewWorldOfDarkness'' is more a DarkWorld. But if you go deep enough, you get to the parts of the Shadow Realm taken over by lords among the Spirits, and then the rules disappear.
* ''TabletopGame/{{Warhammer 40000}}''.
** Aside from the mentions in the literature section above, ''everything'' in the Eye of Terror ends up this way, as well as the Maelstrom (basically a mini Eye of Terror that doesn't even have the decency of an explanation of how it started). Any place a Warp Rift is opened starts to slowly turn into one of these, and if the rift is left unchecked it can end up turning the entire planet into a [[WorldOfChaos Daemon World]]. And that's just what happens when a ''tiny fraction'' of the Warp leaks into the real world...
** The Dark City of Commorragh, home of the Dark Eldar, is also an example, being an enormous collection of realms located inside the Webway (a network of warded tunnels in the Warp), linked together with portals. It's basically Escher on crack and populated entirely by sadistic murder-elves. To make matters worse, in some parts the wards that separate the Webway from the Warp have become weakened, leading to things like districts where shadows come to life and things from outside reality lurk.
** Necron tomb worlds are examples of non-Warp related eldritch locations. The Necrons' mastery over science allows them to create spaces that follow a higher order of geometry than we're used to, resulting in things like buildings that are bigger on the inside.
** Even Eldar Craftworlds are such. They are not planet sized spaceships, but rather entire fleets that gathered together for mutual protection, linked by gates and warps that are tangental to the Webway as a whole. Any given door doesn't open onto whatever's on the other side, but rather to wherever you are wanting to go in the Craftworld itself. On top of this, the physical linkages joining the Craftworld is made from, effectively, psychic powers turned into a solid, called Wraithbone - and acting as a conduit for the souls of every Eldar whose Soulstone was recovered. And at the core of each Craftworld is an area called the Dome of the Crystal Seers. The apparent statues in here aren't - they're the solidified bodies of the greatest farseers of the craftworld, converted into solid wraithbone.
* ''TabletopGame/MagicTheGathering'':
** The locations associated with its resident {{Eldritch Abomination}}s, the Eldrazi; in particular, a combination of solitude and proximity to the Eye of Ugin, which sealed the Eldrazi within the plane Zendikar, cost the planeswalker Sarkhan Vol his sanity for a time, and it wasn't until several months after leaving that he had fully recovered.
** Innistrad isn't as bad as Zendikar [[spoiler:until Nahiri summons Emrakul to it]] but there's clearly something ''off'' with its moon. The moon of Innistrad is a powerful source of mana of multiple types and is responsible for the existence of Innistrad's various supernatural beings: angels, werewolves, [[spoiler:and the vampires since Edgar Markov became the first vampire by drinking angel blood]]. The Helvault, a nigh indestructible prison for demons, was created from a fragment of the moon. [[spoiler:The moon itself eventually becomes Emrakul's prison.]]
* In ''TabletopGame/{{Nephilim}}'', Selenim are capable of creating Realms, pocket universes that exist according to their will, which turn out like this trope.
* Most of the ''TabletopGame/JAGSWonderland'' setting has this in spades. There are eight layers of reality, referred to as "Chessboards." You live on Chessboard Zero. Chessboard One is more or less identical, except everyone's kind of nuts. Chessboard Two is a run-down, dilapidated DarkWorld. Chessboards Three through Six are a sliding scale of CloudCuckooLand and this trope. And Chessboard Seven can barely be called reality by any stretch.
* ''TabletopGame/ArkhamHorror'' allows the players to visit the locations from H.P. Lovecraft's mythos, like the Plateau Of Leng, Yuggoth, and R'lyeh.
* In ''TabletopGame/{{Dragonstar}}'' there is a large region of space outside Imperial space known as the Dark Zone. Few who venture into it ever return, but the few who do speak of darkness and terror. It's also the setting's counterpart to the Far Realm in that it's the home of mind flayers (their original home, it is speculated) and other aberrations.
* In ''TabletopGame/BleakWorld'' this is what the Death Beyond Death is, if a ghost dies they go to a place where they are in constant pain, but can never gain the release of going insane. The whole area is guarded by [[EldritchAbomination The Caretaker]] which is liquid field of darkness filled with constantly disappearing eyes and mouths
* In the game ''Magical Burst'', Youma, the creatures {{Magical Girl}}s fight, frequently surround themselves with a distortion in the tapestry of the world called a Nightmare. For most people, this manifests as a vague feeling of dread, owing to how {{Muggles}} cannot even ''perceive'' Youma or their influence, much less hurt them. For Magical Girls and those attuned to magic, the Nightmare appears as an increasingly surreal region of distorted reality, getting weirder and weirder as one nears the Youma.
* The titular setting of ''TabletopGame/BetrayalAtHouseOnTheHill'' always has a random layout, and can have things such as walls that devour you and spit you out elsewhere.
* The cosmos of ''TabletopGame/{{Nobilis}}'' is pretty much made up of Eldritch Locations, all of which run on their own set of rules - ''including'' mundane Earth, which is a fantasy the Earth created for itself after the trauma that destroyed the dinosaurs, a way for it to deny the existence of karma and thus the belief that it deserved that trauma. It's self-maintaining, self-rationalising... and overstretched, as it's getting far too complex to sustain.
[[/folder]]

[[folder:Tropes]]
* The SugarBowl is a strange form of this. It may be depicted as a genuinely nice place, or as it was in the article. However, there's no denying that a place with licorice trees and structurally sound buildings of candy would belong here.
** Likewise, ''VideoGame/AnimalCrossing'' definitely exists in one of these [[FridgeLogic if you think about it hard enough]]. This has been well-documented in many {{Dark Fic}}s.
* The ClownCarBase also fits this trope in a way, especially when the trope is {{lampshade|Hanging}}d, revealing it to be not just a perspective oddity, but a genuine physically disproportionate building.
* A LevelAte is a place where terrain is GiantFood, often a humorous version of this sort of thing.
* Many {{Lost World}}s are this in a nutshell.
* A DarkWorld can function as an Eldritch Location when it's explicitly evil or "wrong", but a few morality neutral Dark Places are natural "night side" reality counterparts to our own.
* A PlaceBeyondTime is this by its very nature.
* An EldritchStarship can easily be an Eldritch Location with a hyperdrive.
[[/folder]]

[[folder:Video Games]]
* ''Franchise/ShinMegamiTenseiPersona'':
** The series in general has a more benevolent but still bizarre example in the Velvet Room, a room covered ceiling-to-floor in blue velvet that exists outside of time and space, changes appearances with each game, and sometimes isn't even a room (in ''3'' it's an ever-ascending elevator car, and in ''4'' it's a limousine traveling through space.) All of its denizens - the master, Igor, the pianist and singer in the first two games, the painter in ''2'', Elizabeth and Theodore in ''3'', Margaret in ''4'', and Caroline and Justine in ''5'' - are all AmbiguouslyHuman.
** The original ''VideoGame/{{Persona}}'' has a slew of them, courtesy of most of the game being set in [[spoiler:a parallel dimension formed from the thoughts of IllGirl Maki Sonomura, courtesy of a device called the DEVA System]]. The most prominent in the game would be [[spoiler:Avidya World, the embodiment of Maki's darkest thoughts and the VeryDefinitelyFinalDungeon]]. ''Your own high school'' can also get turned into one if you partake the optional Snow Queen Quest instead: if you find a mask inside the school's gymnasium, the spirit inheriting it turns it into a frozen ice palace surrounded by three arcane towers, and you have to trek all three and collect twelve mirror shards in order to break the spell.
** While most of the dungeons in the ''VideoGame/{{Persona 2}}'' duology are set in the real world, [[YourMindMakesItReal the ever-omnipresent ability to make rumors into reality]] add an extra layer of strangeness to them all. The most straightforward example is [[spoiler:Monado Mandala, Nyarlathotep's domain,]], which you only see in the second half of the duology (''Eternal Punishment''): it exists in a space-like area, with pathways and mandalas of light serving as its sole building bricks.
** ''VideoGame/{{Persona 3}}'' has Tartarus (pictured above), an [[ChaosArchitecture ever-changing]] tower that only exists during the Dark Hour, and acts as a pathway from the world of Death and the Collective Unconsciousness from which humanity's Shadows can manifest. [[UpdatedRerelease FES]] adds the Abyss of Time as its inverted twin.
** ''VideoGame/{{Persona 4}}'' has rather the creepy TV World, which once again, is the Collective Unconsciousness being forced to manifest via the "mind" of mass media. [[spoiler:Subverted in the True Ending, where lifting the final veil of deceit from mankind's heart turns the Collective Unconsciousness itself into the GhibliHills.]]
** ''VideoGame/{{Persona 5}}'' has the Palace, a region inside the [[MentalWorld Collective Unconsciousness]] that can create a mirror of reality based on the warped desires of humans, and you can only get there with a mysterious phone app. The underground maze of Mementos serves as the Palace for most of humanity, but those with especially potent, twisted desires can create their own palaces that reflect their state of mind, much like the dungeons of the Midnight Channel in ''Persona 4.'' The creators of the more unique palaces serve as the major bosses for the game.
* Bacterian, the BigBad of the ''VideoGame/{{Gradius}}'' series qualifies: He is a GeniusLoci HiveMind that uses psychic powers to control his fleets. Every time he's defeated, the pieces of him regenerate to form new Bacterians. Gofer, Venom, Zelos, and some other large Bacterians also qualify.
* The Pfhor ship of ''VideoGame/{{Marathon}}'' seems to be mostly organic, with green liquid all over the place. The gravity is low, too. The creepy music doesn't help either. ''Marathon's'' game engine actually ''encourages'' non-Euclidean level design because of the way it implements overpasses. Several levels have passageways that pass through each other as an intentional MindScrew, and some third-party mapmakers have taken it to a very confusing extreme.
* ''Franchise/SilentHill'' features a weird variation of this trope through the eponymous town, which may cross over with, unusually, EldritchAbomination and GeniusLoci. Though its exact nature is [[MindScrew very much up for debate]], it appears to be abandoned and shrouded in fog, day and night come randomly, and a nightmarish [[DarkWorld "otherworld"]] version of the town lurks beneath the surface and can overtake you at any moment. The otherworld draws its form [[SelfInflictedHell from people's minds]], sometimes [[PsychologicalTormentZone the protagonists]] and sometimes [[RealityWarper another character entirely]]; quite a few [[EpilepticTrees epileptic forests]] have grown from trying to explain it all. It's worth pointing out that DJ Bobby Ricks, one character in ''VideoGame/SilentHillDownpour'' has pointed out that the town has 'rules,' and it is not keen on people disobeying it. If the town wants you to stay inside, if it wants you to learn something, you will. Possibly for eternity, as one character has been stuck there, delivering mail to parties unknown (possibly from the town itself) for 200 years. Even the apparent deity or demon worshiped by the town's resident cult, [[ScaryAmoralReligion The Order]], might just be the town acting upon the cult members' beliefs and desires.
* ''VideoGame/{{MOTHER}}''
** In ''[[VideoGame/CognitiveDissonance MOTHER: Cognitive Dissonance]]'', you are sent into one of these by Niiue to distract Giygas, where everything is red, there's chaotic forces of PSI, and the alien himself waiting in the center of it all with the Devil's Machine.
** In ''VideoGame/EarthBound'', once the Devil's Machine is turned off, it's implied that Giygas might just be huge and dimension-warping enough to be not just an EldritchAbomination, but one of these in his own right. And before that, Ness and Jeff get to visit Moonside, which also qualifies.
** ''VideoGame/{{Mother 3}}'' has the Empire Pork Building, which is an unusual sort of eldritch location. Every floor you visit seems normal in its own right, at least as far as the Mother series goes. A lake full of hippos, a hall full of bathrooms, a construction site, etc. But they're all so disconnected and irrelevant to each other, and supposedly each one is the 100th floor.
* ''Franchise/TheLegendOfZelda'':
** The various incarnations of the LostWoods in the ''Zelda'' games: they either turn off your minimap, making navigation extremely difficult, or in ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle of Seasons]]'', one place is even completely off the map, plus the place where Like-Likes fall from the sky. In ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'' it's implied that anyone who isn't of TheFairFolk would tend to become hopelessly lost, eventually turning into skeletal imps doomed to haunt the forest forever.
** ''VideoGame/TheLegendOfZeldaSpiritTracks'' has the final area, the Dark Realm. Accessed through a dark portal that can only be found with a magic compass, it basically looks like Van Gogh's ''Starry Night'' in a black hole. Beneath the train tracks is some kind of strange, smoky/watery "ground" that gives way to a completely different landscape right beneath it.
** The setting of ''VideoGame/TheLegendOfZeldaMajorasMask'' is a pseudo alternate dimension called Termina, with several oddities (like the physics of Stone Tower Temple, as well as the SurrealHorror elements involving the Moon and the distinct regions) that violate many logics. The fact that the game's titular villain is a reality warping, psychopathic EldritchAbomination contributes to this as well.
* The inner sections of the Pyxis (A.K.A the Box) from ''VideoGame/CliveBarkersJericho''.
* ''VideoGame/{{Chzo|Mythos}}'' is both this and an EldritchAbomination, a pain elemental who satiates himself with tortured victims trapped inside his labyrinthine corridors for all eternity.
* The interaction of {{Hyperspace|IsAScaryPlace}} and Pathspace in ''VideoGame/ImmortalDefense'' produces one of these. From Pathspace, Hyperspace looks like a twisty path across a 2D plane, and from Hyperspace, Pathspace is the home of vindictive demigods who rain psychic death upon unwary travelers. [[spoiler: The ''protagonist'' is one of these demigods.]]
* ''VideoGame/DwarfFortress'':
** [[http://www.bay12forums.com/smf/index.php?topic=61507.msg1400676#msg1400676 The Adamantine Spire]], a.k.a. the Adamantine Space Elevator. The weirdest part is that even when other people tried to recreate it using the same worldgen seed, it didn't show up. Current theories are that it's due to [[GoodBadBugs interference from old save data]].
** FridgeHorror: Considering what adamantine veins like the spire usually [[TheLegionsOfHell contain,]] it looks like whatever counts as Heaven in the Dorf 'verse is in for some serious [[UnusualEuphemism Fun.]]
** Some of the more convoluted succession forts such as ''LetsPlay/{{Battlefailed}}'' become this. Battlefields had the temporally locked dwarves in the arena, Headshoots had the room outside of space, etc.
** And then there's the evil biomes. Rains of blood and FogOfDoom that causes any living thing exposed to it a horribly painful death if they're lucky or turns them into a [[HumanoidAbomination thrall]] if they're not, eyeballs and tentacles growing out of the ground, a 50/50 chance of anything that dies there spontaneously reaminating into a zombie if the body isn't [[ChunkySalsaRule thoroughly destroyed]] and native wildlife that would make [[VideoGame/{{Doom}} Doomguy]] feel right at home.
* ''Franchise/{{Pokemon}}'':
** The Distortion World from ''[[VideoGame/PokemonDiamondAndPearl Pokémon Platinum]]'' falls under this. Floating masses of land in a giant vortex, giant plants that sprout randomly out of nowhere, disappearing platforms, and waterfalls that float up are just a few features to be found. And that the ''only'' thing living in there is the EldritchAbomination known as Giratina. There's also the immense GravityScrew of the Distortion World. The waterfall isn't the only thing that goes the wrong way there; the Distortion World is the ''only'' place in the ''whole main series'' where you navigate by jumping onto those floating platforms and ''walking sideways''. It's also impossible to ride your bike there.
** Ultra Space, the home dimension of the Ultra Beasts from ''VideoGame/PokemonSunAndMoon''. We don't see too much of it, just a multicolored barren cavern, lit up despite the absence of any apparent light source, filled with various Nihilego (read:toxic parasitic jellyfish made of shapeshifting glass) floating around and occasionally phasing in and out of existence. The characters comment that the air feels strange and it's hard to breathe properly. The Rotom Pokedex, which is otherwise always chatty and displays a map of the area, is completely silent and its screen is filled with static, completely inoperable.
** In ''VideoGame/PokemonUltraSunAndUltraMoon'', you see more Ultra Spaces and you can even fight the Ultra Beasts on their Home Turf. From what the trailers have shown, Kartana (read:living origami who can cut through steel) resides in a strange forest, Buzzwole (read:muscular humanoid mosquito) resides in one of the least eldritch of them as it looks more like a jungle in broad daylight (though that may invoke [[DaylightHorror another trope]]) and Xurkitree resides in what looks like the inside of a chaotic machine.
* The Dark Rift from ''VideoGame/SkiesOfArcadia'', a high-pressure storm system that can't be crossed the way regular rifts can even with a fully-upgraded ship and remains even after the other rifts have calmed. Inside it is an alien landscape full of corridors that connect in odd ways, strangely-oriented landmasses, and plants and creatures very much unlike the ones seen anywhere else in the game. At its heart is a moon stone that doesn't match any of Arcadia's 6 moons.
* ''VideoGame/{{Skullgirls}}'':
** Gehenna, a WombLevel set before a lake of blood whose background features several eyes imbedded into the level that follow the characters as they fight. [[HellIsThatSound Yes, that's screaming you can hear in the soundtrack.]]
** Nightmare Crest is a twisted version of the familiar Maplecrest stage that acts as a setting for the game's BattleInTheCentreOfTheMind stages - the surroundings are muted and greyscale, the people that are normally bright and colourful on Maplecrest are formless shades with glowing white eyes and while the black leaves are frozen in mid-fall, the sky above is a rapidly-swirling red and purple storm.
* ''Franchise/{{Castlevania}}'':
** It's an Eldritch Location and houses several {{Eldritch Abomination}}s to boot. The discrepancy that crops up between the games is {{lampshade|Hanging}}d and {{handwav|ing}}ed with a comment that the castle is "[[ChaosArchitecture a creature of chaos]]." The castle can take many shapes and forms, picking and choosing when and if it wants to follow the laws of physics.
** In ''VideoGame/CastlevaniaSymphonyOfTheNight''), the whole castle ''has an inverted duplicate'' revealed halfway through. You and the monsters fall towards and walk around on the ceiling. All the furniture is still on the floor. It is never explained why a second castle just appears out of the clouds, nor why it's upside down. And then there's the two mirrored split castles in ''VideoGame/CastlevaniaHarmonyOfDissonance'', which are somehow both the extension of Maxim's will.
** Dracula's demon castle continues to follow tradition in the [[VideoGame/CastlevaniaLordsOfShadow2 Lords of Shadow]] subseries, with that twist that an entire city gets built onto the ruins at one point. While being on top of the castle usually isn't a problem, it does mean that someone can occasionally walk right outside of their office and wind up right in the seat of Dracula's power.
* ''Franchise/KingdomHearts'':
** Both [[VeryDefinitelyFinalDungeon final levels]] of ''Franchise/KingdomHearts I'' and ''II''. The one from [[VideoGame/KingdomHearts the first game]], appropriately titled The End Of The World, is basically the remains of any and every world destroyed by TheHeartless, and the one from [[VideoGame/KingdomHeartsII the second game]], The World That Never Was is a dark city overrun by Heartless overlooked by the warped castle that is the headquarters of Organization XIII, and its ''[[WeirdMoon moon]]'' is [[MacGuffinLocation the heart of reality itself,]] [[TitleDrop Kingdom Hearts]] (or at least, a functional replica).
** In fact, the concept of the worlds makes them Eldritch Locations: they are apparently separated, but are described as sharing the same skies. All the worlds used to be one large world, but it was shattered in the Keyblade War, leaving only shards behind, forever separated by metaphysical barriers that few can traverse.
** The Realm of Darkness is its own twisted version of reality. As the name suggests, it's pretty dark, much of it seemingly made up of gray rocks with cracks out of which ghostly blue light faintly shines. There is no sky, no horizon, just pure blackness. Seemingly no living things other than the Heartless (if they count as such). But the most disturbing thing about it is that ''time'' doesn't flow in the Realm of Darkness. Characters who are trapped there do not age and do not sleep, and have no way of marking the passage of time. [[spoiler:Aqua is surprised to hear that she's been trapped in there for ''over ten years'' from the perspective of everyone else.]] And the worlds that fall to darkness? They get trapped in the Realm as well, transformed into twisted caricatures of themselves floating in a void that only barely obey the laws of physics.
* ''VideoGame/ShinMegamiTenseiStrangeJourney'' has the [[DarkWorld Schwarzwelt]]. It is effectively a [[NegativeSpaceWedgie void]] over Antarctica where [[HellGate demons appear]], overwriting Earth with their own reality. The Investigation Team's mission is to analyze and nullify the Schwarzwelt before it can consume the entire world. The game over screen shows what happens if your character dies...it ain't pretty. The fun part is that the UN sent cameras into the Schwarzwelt during the planning stages...and ''nobody'' believed the results (one of them was a ''shopping mall''). Turns out they were all accurate (but you don't want to eat the food in the shopping mall...).
* ''[[VideoGame/ShinMegamiTenseiIIINocturne Shin Megami Tensei: Nocturne]]'' mostly takes place within the Vortex World, a chaotic, demon infested realm that the Earth reverts to when it comes time for a new world order to be decided. Naturally, it's up to you to shape it as you see fit. For bonus points, it's a truly literal form of TokyoIsTheCenterOfTheUniverse.
* And in ''VideoGame/ShinMegamiTenseiIV'', we have the final dungeons for Law and Chaos, respectively: Purgatorium and Lucifer Palace. The Monochrome Forest also counts, as well as the various Demon Domains littered around Tokyo.
* Xen, the "border-world" from ''VideoGame/HalfLife1''. It seems to consist of a bunch of small rocky islands floating in the middle of a greenish void, and yet apparently has gravity independent of those islands and a breathable atmosphere. It's also inhabited, although [[AllThereInTheManual the fluff]] indicates that the current inhabitants are not native to the dimension, and came from someplace else.
* Every time you fly through Bydo Dimension in ''VideoGame/RType'', especially the MindScrew territory of the final stages of ''Delta'' and, well, ''Final''. To put in specific terms, the Bydo Dimension in ''Delta'', which is depicted in the picture above, looks like a twisted version of our world with babies encased in crystals, upside-down buildings, huge strands of DNA, and a weird forest of Bydo Trees. The Bydo Dimension in ''Final'' is an abyss full of fluid inhabited by eyeballs and the creature implied to be the real source of the Bydo. The Bydo Tree forest bit also appears in ''Final'' as a hidden stage. There is also a stage in ''Final'' that takes place in a weird dimension where there is only the player, a slug Bydo named Nomemayer, and particles of light that can turn anything and anyone into a Bydo. And there's Anti-Space, a dimension ''created'' by some Bydo guys named Gridlock.
* On the final floor of ''[[VideoGame/{{Dgeneration}} D/Generation]]'', what once looked like an ordinary office building (albeit with hyperactive security measures) suddenly turns into a bizarre surreal nightmare thanks to the title entity. There's also a headless guy.
* ''Franchise/DragonAge'':
** The Fade, the place people (except dwarves) go when they dream, full of spirits and demons and doubling as Heaven, Hell and everything in between. Characters are trapped in their own "mini-Hells" ([[IronicHell reflecting their own lives]]), the sky is full of floating mountains (heavily implied to be other, infinitely large hells) and the [[{{Hell}} Black City]] is visible wherever you go.
** And in the DLC ''Witch Hunt,'' Morrigan implies that beyond the Fade there are places that are even stranger where [[spoiler: she's keeping her Demon Baby safe from her evil mom.]]
** Amgarrak Thaig, the titular location of ''Golems of Amgarrak'' is definitely one, protected from the outside by a maze of shifting mist and having Lyrium Wells that were designed to phase-shift people into alternate versions of the Thaig in order to better safeguard its secrets.
** The sequel has [[spoiler:Kirkwall. Yes, that's right: the main setting. It's subtle, though; you can go through the whole game just thinking the whole place is a [[CrapsackWorld Crapsack City-State]], but certain notes you find indicate that not only is the Veil unnaturally thin over the entire area, entire neighborhoods are constructed in the shapes of blood magic sigils, there are likely lakes of blood beneath the streets that still haven't dried, but demons are actively drawn to the place like flies to the point where they occasionally hunt non-mages because ''there's too much competition''. And that's ''before'' you factor in [[SealedEvilInACan Corypheus']] [[TheCorruption corrupting]] presence from his Grey Warden Prison in the nearby Vimmark Mountains.]] It - or very nearby - is actually where [[spoiler: the magisters entered the Black City (sacrificing hundreds of slaves in a blood ritual in the process) and were transformed, like Corypheus, into darkspawn, causing the Blights.]]
** The [[spoiler: Primeval Thaig]] is definitely one, [[spoiler: built by prehistoric Dwarves that worshipped a pantheon of deities, constructed using magic thus giving it some degree of AlienGeometry, posessing a unique form of Red Lyrium running throughout the structure itself and inhabited by creatures like the Profane that Varric claims were supposed to be ''myth''. It was also the location where Hawke and company first encountered the [[ArtefactOfDoom Lyrium Idol]]]].
** In an older Creator/BioWare example, the Spirit World of ''VideoGame/JadeEmpire'' is similarly weird.
* ''VideoGame/{{Homeworld}}: Cataclysm'''s Beast is said to come from "Outside".
* The NES game ''VideoGame/TheMagicOfScheherazade'' has the EldritchAbomination Goragora [[SealedEvilInACan trapped in ancient times]] in the "Dark World" (not to be confused with a DarkWorld), and the villain threatening to release it once more. He eventually learns the hard way that EvilIsNotAToy, and begs the heroes to enter the Dark World and keep it from escaping. Beyond the gate and past the PointOfNoReturn, the VeryDefinitelyFinalDungeon looks like a starswept black abyss with walls and columns made out of transparent bubbles.
* The GBA and PSP remakes of ''VideoGame/FinalFantasyI'' have the four special dungeons that change floor permutation with every visit. Furthermore, some of these floors have environments that should not be able to exist in a subterranean environment, such as overworlds, {{Floating Continent}}s, and thriving towns that look just like the ones on the surface, ''complete with shops and inns''.
* In ''VideoGame/FinalFantasyII'', [[spoiler:the Jade Passage and Pandaemonium]].
* In ''VideoGame/FinalFantasyIX'':
** [[spoiler:Terra, a parasitic other planet, actually inserted itself into Gaia long ago and is feeding off the planet from the inside.]] Creepy.
** Another present in the same game is [[spoiler: Memoria, a world formed from the collective memory of the entire planet.]]
** The Hill of Despair where the party fights Necorn which is apparently the [[spoiler: Afterlife.]]
* ''VideoGame/FinalFantasyV'' has the [[VeryDefinitelyFinalDungeon Cleft of Dimensions]], which is a patchwork of areas earlier swallowed up in the Void and home to many {{Eldritch Abomination}}s including the game's two NintendoHard {{Bonus Boss}}es. The UpdatedRerelease added the [[BonusDungeon Sealed Temple]], home to even more {{Bonus Boss}}es, including the HumanoidAbomination who the legendary weapons were crafted specifically to fight.
* ''VideoGame/FinalFantasyXI'' has a few that qualify, and they all tend to follow the "islands floating in nothingness" style:
** The Promyvion areas appear to be corrupted, shadowy versions of other existing areas, topped off with haunting music and freakish looking monsters.
** The Walk of Echoes is an area of disconnected structures floating in nothingness. [[spoiler: It pretty much exists outside of time, and Atomos himself can be seen in the sky at all times.]]
** The added Provenance areas, [[spoiler: which are described as being the place where the source of all life comes from.]]
* Although featuring fewer locations than one might expect, ''VideoGame/FinalFantasyXIV'' still features some notable examples, especially those found in the ''Heavensward'' expansion. Perhaps the most obviously eldritch is [[spoiler: the Aery, Nidhogg's lair, which is a ruined Avalonian city held together in a storm of aetheric energy fueled by the dragon's blinding rage.]]
** The strangest location has to be the Palace Of the Dead (making a cameo from TacticsOgre); accessible only through a strange portal in the Black Shroud, the Palace of the Dead is an ever shifting maze filled with monsters, traps, and strange magical items that only seem to function within. The entire palace is filled with a gloom that saps the strength of anyone who enters, reducing them to Level 1 and rendering their equipment useless. Only by condensing one's life force into weapons and armor made of magic can one hope to survive. What's even stranger is how, while decending in the palace, players will rapidly gain levels to the point of exceeding their job level back in the 'real world'. Prior to Stormblood, this even meant learning spells and abilities meant for max level characters while still being low leveled in the "real world". The deeper you go in the Palace, the stranger things become; eventually falling apart into a series of pathways in a misty white void. The 200th floor features [[spoiler:a tranquil looking bench underlooking a tree, in a place completely devoid of enemies. Some players have joked that this is the Palace inviting you to be it's latest denizen. Thankfully it doesn't object if you refuse.]]
* The inside of [[EldritchAbomination Sin]] in ''VideoGame/FinalFantasyX''.
* In ''VideoGame/{{Xenogears}}'', [[spoiler:Deus, already an EldritchAbomination, becomes an enormous EldritchLocation in its own right.]]
* The Dead Sea from ''VideoGame/ChronoCross''. It's the site of a massive TimeCrash, where the canceled BadFuture from ''VideoGame/ChronoTrigger'' tried to reassert itself over Chronopolis. Waves of water, forever frozen in time, wash over the wreckage of the city, and at the heart is the Tower of Geddon, a conglomeration of locations from said canceled timeline haphazardly mashed together. Much later, you also go to the Darkness Beyond Time, where cancelled timelines are sent [[spoiler:and where the Time Devourer lurks]].
* Its predecessor ''VideoGame/ChronoTrigger'' already had the [[PlaceBeyondTime End of Time]], the place where all possible time lines meet. As far as eldritch locations go, it's actually fairly harmless. The UpdatedRerelease added a few more such as the [[BonusDungeon Dimensional Vortexes]], areas where time and space are essentially broken. The Darkness Beyond Time also makes an appearance.
* In ''VideoGame/WildArms2'', [[spoiler:the Encroaching Parallel Universe "Kuiper Belt" is one of the most terrifying examples yet]].
* In the original ''VideoGame/PhantasyStar'' series, the very Algol star system it takes place in is an enormous lock for a dreadful SealedEvilInACan. And the lock isn't exactly completely intact.
* The titular planet in ''VideoGame/{{Albion}}'' looks like some alien world with primitive civilizations at first. Until it is revealed that it operates under completely different laws the Earth does. [[spoiler:The fact that it's actually a sentient (benevolent) being, has something to do with it]].
* The tunnels under ''VideoGame/PathwaysIntoDarkness'''s pyramid are actually the nightmares of a catatonic EldritchAbomination made real.
* Several places in the ''VideoGame/{{Warcraft}}'' universe qualify.
** Chief among them is Outland. It was formed when the planet Draenor was torn apart by multiple interdimensional gateways being opened on the surface. It's now a continent with several different ecosystems, some of which are healthy and normal, or at least, [[PatchworkMap as normal as the rest of this universe]]. However, the [[FloatingContinent continent]] is surrounded by, rather than an ocean, an edge, and if you walk off it you fall into nothingness. It also has an AlienSky, which is sunless but otherwise mysteriously normal in some zones, but looks like energy cascading through space in other places. In several places there are {{Floating Island}}s, some of which have water perpetually falling off them with no source.
** The Netherstorm. Not only is it even more surreal than the rest of Outland, being just a collection of massive floating rocks instead of a single land mass, no one knows where it came from. Every other zone has a clear analogue on Draenor but the Netherstorm doesn't.
** The Maelstrom. A eternal whirlpool full of unstable energies surrounded by an eternal hurricane that was formed when the Well of Eternity was destroyed. The black dragon Deathwing used it as a portal back to Azeroth, almost causing the world to blow up. The constant attention of several powerful shamans is required to keep the world from falling apart through it.
** Deepholm. It can be reached by flying into the Maelstrom. It is the home of earth elementals and other creatures native to the elemental plane, so it's not ''supposed'' to be comfortable to flesh-and-blood creatures like playable races. It is a massive cave with a rock-based ecosystem, rock pillars that float in the air, and spires that regularly explode and reform. Most of the elemental planes are odd like this, but with another element in the place of rock.
** Karazhan is a large black tower in the mostly empty Deadwind Pass. It was once home to Medivh, The Last Guardian, and sits atop a point where every ley line (think veins, but instead of blood it's magic) in the entire world intersects. Time itself gets lost within Karazhan, allowing visions of past, future and other worlds to pop in and out unexpectedly. One of Medivh's theories is that the Deadwind Pass was formed because someone would eventually build a tower there, rather than the tower being built where the Pass was. Also, there is an inverted Karazhan under the main one, and the main one exists in at least two parallel universes at once. There's also the odder features inside and around the tower.
* The World of Mammon in ''VideoGame/{{Quest 64}}''. The environment drastically changes with each transition, doors never lead to the same place twice, the sky is always the wrong the color, and the music is creepy as heck. The inhabitants are just as unnerving: among them are [[LivingStatue Living Statues]] that have more than a passing resemblance to [[Series/DoctorWho the Weeping Angels]]. Of course, the entire place is the prison/domain of a demonic EldritchAbomination.
* ''VideoGame/{{Minecraft}}'' has a couple of these:
** The Nether is a [[HyperspaceIsAScaryPlace deliberate example]]. Once you finish the mining tech tree and craft a diamond pickaxe, you can build an obsidian HellGate and enter a skyless world filled with steep cliffs, lava lakes, and giant jellyfish that spit fireballs at you while flying out of reach of your arrows. Not only will your compass spin around aimlessly, so will your watch. However, any distance traveled inside the Nether is multiplied by eight once you return to the normal world, so it can be used to travel long distances relatively quickly, once you finish digging tunnels and building bridges.
** The End, a single barren island floating in an infinite void. It's home to the Endermen, and can only be accessed by portals deep in underground ruins... and can only be exited by defeating the [[FinalBoss Ender Dragon]].
** An [[MinusWorld unintentional version]] of this is the Far Lands. In the pre-release versions of Minecraft, travelling roughly 12 million meters in any one direction makes the game generate areas like [[http://hydra-media.cursecdn.com/minecraft.gamepedia.com/c/cc/12550821line.png?version=6d6925e5d08789a5400fcd256252a8dd this]], in addition to huge amounts of lag and "stuttery" movement. Travel even farther, and around 32 million meters, physics and lighting just stop working altogether. The Far Lands were acknowledged by the creators, who [[AscendedGlitch planned to keep them in the game]], but changes to the way terrain is generated effectively removed them before release.
** ''VideoGame/{{Thaumcraft}}'', a popular GameMod, contains a more traditional example, called the Outer Lands. You get there by [[spoiler:performing a ritual called "Opening the Eye" on a floating Eldritch Obelisk]]. When you arrive, you'll find [[spoiler:a dark maze filled with Eldritch Abominations, with a boss at the end]].
* ''VideoGame/TheBreach'' starts off on an ordinary spaceship, but towards the end things start to ''shift'' into a mountainous region filled with yellow mist and glowing glyphs.
* ''VideoGame/MassEffect2'' has [[spoiler:the derelict Reaper, which can still indoctrinate despite being dead for ''37 million years'', a not-so-derelict Collector vessel and finally the Collector Base, an immense space station located in the accretion disc at the heart of the galaxy, which serves as TheVeryDefinitelyFinalDungeon. The vessel is even creepier than the base itself since in the latter, you are almost continuously under attack, while in the former, about the first two thirds of the mission consist of exploration without enemy contact - [[{{NothingIsScarier}} which, in this environment, only makes it worse]].]]
* The Subspace of "Subspace Emissary" in ''[[VideoGame/SuperSmashBros Super Smash Bros. Brawl]]'' is this coupled with AmazingTechnicolorBattlefield. And it only gets weirder when the parts of the regular world that were dragged into the Subspace are assembled into the [[MarathonLevel Great Maze.]]
** In ''Wii U/3DS'', [[spoiler:Master Core itself turns into one of these, named 'Master Fortress'.]]
* ''VideoGame/TheLegendOfSpyro'' has Convexity, a gateway between the main world and the Dark Realms, occupied by the Dark Master. It's the location of the final boss battle, featuring floating platforms and strange whale-like creatures with tentacles.
* ''VideoGame/ElShaddaiAscensionOfTheMetatron'' has the Tower, where the majority of the game takes place. Each floor of the tower is ruled by a fallen angel and is essentially its own pocket universe where that angel and its followers live. Locations range from a burned-out wasteland to a cutesy cartoon-like world of colorful blocks and balloons to a futuristic {{Tron}}-like cityscape (complete with cycle combat!) to an underwater world. There's also the Darkness, a location that corrupts everything that falls into it [[spoiler:and is where the souls of the angels' followers end up instead of Heaven]].
* ''VideoGame/FallenLondon'':
** The Neath from the first game and its spinoff ''VideoGame/SunlessSea''. There is a theory that the giant cavern is the skull of a dead god. It is very difficult to die there because it's downstream of Hell. Finding one's way around it can be ''literally'' maddening. An unnerving number of the places you visit are probably alive. You might accidentally walk into someone else's memories. People there keep tigers as pets, make wine out of mushrooms, and play a boyish game based upon stabbing other people. The islands far beyond London keep swapping places when you aren't looking, making maps useless after enough time. You can become used to much of the Neath, but there are a couple places in it that are... different.
** In Polythreme, inanimate objects come alive. A Clay Man explains, "IN POLYTHREME THE BED I SLEPT ON WAS A SLAVE. THE ROOM WHERE I SLEPT WAS HACKED FROM SCREAMING STONE. THE WATER I DRANK BEGGED ME TO STOP. THEY PAID ME IN COIN THAT PLOTTED MY DOWNFALL. THE MEMORIES ARE TROUBLING. THIS PLACE IS BETTER."
** The Iron Republic is a place of true freedom - not even the tyranny of nature rules there. Everything is in a constant state of flux, and the straightforwards interface becomes deranged ramblings. Writing a report on it will net you something either completely blank or ''explosive'', and the punctuation's practically guaranteed to try to eat you. Gather enough protesters and you can literally protest something into existence, or make it disappear completely. The laws of mathematics change every Thursday, which makes accounting just plain intolerable. And even then, what Thursday is probably also changes constantly. And, since it's in both Fallen London and Sunless Sea, you can even ''buy items for the wrong game''[[labelnote:*]]It's been documented you can buy Supplies and Fuel, vital for Sunless Sea but absolutely useless in Fallen London, for no reason at all beyond the fact it's the Iron Republic[[/labelnote]]. The only law is, there is no law.
** The Cave of the Nadir. Lost to history for quite a while, a pain to find even with an enormous archaeological team, pretty much ''everyone'' has an interest in knowing its location, and once there you might wish you never found it. Why? [[spoiler:The entire cave is Irrigo, a mysterious and horribly dangerous color resembling a deep, intense violet. It soaks into you, and stays with you like an insidious radiation, eating away at your memories, your thoughts, and eventually your mind itself. The cavern is full of individuals of all kinds and species that have completely lost themselves, and are completely unable to remember anything, or think clearly. Prolonged exposure will cause your skull to ''grow bone over your eye sockets'' in a futile effort to stop it. Forgotten memories bounce around the place with no rhyme or reason, and make you remember things you never experienced before departing just as quickly as they came. And if you forget your own name, [[AndIMustScream you can never, ever leave]]. And there are theories this color is what makes the entire Neath an Eldritch Location in itself]].
** Irem was strange. Irem is strange. Irem will be strange. It's basically what happens when you sail straight to the edge of dreams (coming in from an actual physical place), and found a city in the border. Or what happens when you will do that in the future. Either way, it hasn't been founded yet, but you can visit it, and have a jolly good time over there, and come back with not much trouble. You'll have been there when the time comes. And yes, in case you haven't noticed TimeTravelTenseTrouble is a ''huge problem'' when writing port reports.
** The Twin Castles of Frostfound, up North where the ice and cold reign. These two are very, very deeply linked to the Gods of the Zee, and entering them will piss them off, with no seeming reason given. Entering any of the two will start eating away at your mind, particularly your memories and stories, until there's nothing left of you. And a little less unnervingly (which shows by what standards we're playing by now), space inside the castles just doesn't seem to work right. Bringing a certain crewmate inside will lead to you spotting him disappearing through the wall never to be seen again, for example. And if you want to enter, there's no doors. You have to close your eyes and go forward, and you'll just... be there, in a series of chambers that will eat at your mind and/or possessions.
** Avid Horizon. No matter how you twist and turn in your road, if you travel North for long enough, you will end up here. There is no way to continue further North. It's an enormous, unbreachable gate with an odd rubbery texture, guarded by two statues, all of a deep Gant colour. Gant being what remains when all other colors have been eaten. Everyone, even your fungal cargo, is unnerved when approaching the place. The fake stars above start flickering like they're going out as you approach. And the gate isn't a thing. It's a Law. And sometimes, when the guardians aren't aware... the law can be breached. [[spoiler:And somehow, ''somehow'', it leads to outer space]].
** Kingeater Castle. Nobody has any idea what the hell is up with the place. People can willingly give up their sanity, and even their past and future. The sense of a great impending mistake pervades the air as you approach. Praying to the most mysterious of the three local deity-like beings can occasionally send you there for no given reason. Something about the place just conducts you towards the most horrible decisions. And a terrible hunger seems to reign all throughout it. It's quite remarkable that even in a place like the Neath, where the strangest of all things get explanations and are considered normal, this is one place that is still feared and unexplained.
** And in this literal ocean of madness, there manages to be an inversion to this trope in the form of Aestival. A simple, quiet island of sand and rocks and some vegetation. Nothing more to it, because the Sun shines from outside and into it through a hole in the Neath, and the Neath's local variety of weirdness tends to react [[WeakenedByTheLight very badly]] to it. Shame this also includes people who've lived in the Neath for any significant length of time.
** The zeefloor proves itself just as strange with the ''Zubmariner'' expansion. It rearranges itself ''much'' more often than the surface does, the wildlife goes from merely being more awful than surface versions of the same to making absolutely no biological sense, it occasionally grows bubbles of impossible colors with terrifying effects, random clouds of pure darkness can appear from out of nowhere, it occasionally has a gigantic eye that can be sailed into and contains MindScrew incarnate and the shadow is so intense ''[[EldritchAbomination things]]'' can slither out of it every now and then. And then there's the various Abysses, where [[HumanoidAbomination the Lady in Black]] can be found... Ironically enough, the underwater ''ports'' are all relatively normal in comparison to some of the above. The strangest of them by our standards ([[ElephantGraveyard the Gant Pole]], [[CyberneticsEatYourSoul Anthe]], [[WombLevel Nook]] and [[StarfishAlien Aigul]]) are just par for the course by the time you can submerge, and the strangest for the Neathers (Hideaway, a city atop a GiantEnemyCrab) is outright ''normal''.
** Not only does the Neath contain several of these locations, it's the only place where the usual pathways to yet another, ''much'' bigger Eldritch Location will work as such. The place is Parabola, and the pathways are dreams, Prisoner's Honey, and mirrors. Yes, normal mirrors, and any sort of dream you have will take you to Parabola for a brief time. And people that are going entirely insane and having the most horrible nightmares have been known to just... ''stumble'' into the place by accident with no way out for a long time. Its outer borders, the Mirror-Marches, look like an endless jungle with oddly familiar ruins of the previous four cities, Earthen fauna that acts a little too strangely, and with framed mirrors partially embedded into the ground everywhere. These mirrors are the other side of regular mirrors back in the Neath, and you can peer back into reality through them. The laws of reality are just a bit more tenuous here, and you can pull off certain tricks that even the Neath's lax rules don't allow. It's also stated that deeper into Parabola, things get much stranger, including things like a marsh where the light of every snuffed candle comes alive. The rulers here are known as the Fingerkings, [[spoiler:who are tiny, flying snakes with RealityWarper powers within Parabola and who like to [[GrandTheftMe snatch up dreamers' bodies to check out reality]], and also make deals with people to give them strange powers, being particularly fond of stage magicians]]. Cats love the place, however (though they despise the Fingerkings), probably because they get to decide their forms in here and [[PantheraAwesome enjoy being big, badass cats]].
* The Otherworld, the final location and lair to the FinalBoss from ''VideoGame/{{Miitopia}}''. It is a strange, allegedly cursed place in which, according to [[spoiler:the Ex-Dark Lord]], no regular human could survive. It is a psychedelic and eerie place populated by sentient rocks and aliens, with weird undulating lines dancing in front of a deep purple void and the floor is in blurry colors with occastional star patterns racing through it. Its most distinctive feature though is the countless luminescent stolen Mii facial features seen floating in the background and the occasional purple bubble floating in the foreground. It is also unclear whever the Otherworld is set in space or in another dimension.
* The '''entire''' world of ''VideoGame/{{Limbo}}''. It's dark (as in pitch-black save for the rare spot of light), silent, and [[EverythingTryingToKillYou literally everything is after your blood]]. [[PuppeteerParasite Or your brains]].
* ''VideoGame/{{STALKER}}'' is set in the Zone of Exclusion surrounding the Chernobyl Nuclear Power Plant after its infamous meltdown. Referred to simply as "the Zone", said location has become a place when only the most heavily-armed and foolhardy ever set foot due to massive amounts of both leftover nuclear radiation and ''[[RealityIsOutToLunch incredibly weird shit]]''. Aside from all the "normal" stuff - wild dogs, mutants, bandits, military troops, radiation pockets, and hostile factions - you have the anomalies: getting too close to what looks like a patch of empty air can [[LudicrousGibs reduce you to bloody chunks]]; that lightning-looking ball hovering over the ground can electrocute you; that patch of air that looks like it's shimmering in the sun can spit out a jet of fire that will burn you alive instantly if you're not protected enough. And those are just the ''obvious'' hazards. At one point, you encounter an endlessly looping room. At another, [[AlienGeometries you find a lake that is also a hill, and that lake flows several yards into the air]]. If you're caught improperly sheltered during a [[RedSkyTakeWarning blowout]], you'll find it's even more bizarre and even more dangerous than ever. [[YourHeadAsplode Briefly.]] [[BilingualBonus If you understand Russian]], the other stalkers have some... ''interesting'' stories to tell by the campfires, too. And lastly, the artifacts, your main source of income and stat boosts for the games, are are formed by the previously mentioned anomalies, so they're found exclusively around these areas.
* ''Franchise/MortalKombat'':
** The Netherrealm, which is home to the demonic Oni and is generally about the most depressing place you can be. Of course, it is the MK universe's equivalent of Hell.
** There's also the Chaosrealm, where, as the name would imply, nothing makes any sense whatsoever. The prevailing theme of the realm and all of its inhabitants is that they adamantly refuse to conform to any set of rules (especially the laws of physics). It is even implied at one point in [[VideoGame/MortalKombatDeception Deception's]] Konquest mode that natives of other realms who stay there long enough will inevitably be driven insane as their mind struggles to make sense of the place.
* ''VideoGame/BlazBlue'':
** The Boundary can be classified as this - a nexus for all timelines, and so chock-full of nastiness and {{mindrape}} that mere ''entry'' can destroy you in some shape or form. Precisely eight beings are known to have traveled through the Boundary, either for TimeTravel or some other reason.
** Ragna the Bloodedge: Involuntarily dumped into the Cauldron at Kagutsuchi by Nu-13. [[spoiler:Not much is known happens to him at this point, though it's assumed that his soul was either ripped apart by the Boundary or became a new Black Beast, smelted in the cauldron and later released. He later does it again in Chrono Phantasma, this time in a controlled scenario with Rachel's assistance, and emerges 100 years in the past and eventually becomes Bloodedge.]]
** Nu-13: Tosses herself into the Cauldron at Kagutsuchi together with Ragna after impaling them both with her Calamity Sword. [[spoiler:It's never revealed what happens to her at this point, though it's assumed that she either was torn apart by the Boundary or was smelted into a new Black Beast before the ResetButton was pushed.]]
** Lotte Carmine: Willfully entered the Boundary ForScience [[GoMadFromTheRevelation Goes insane due to exposure to forbidden knowledge]], loses his body soon thereafter and becomes Arakune.
** Litchi Faye-Ling: Momentarily enters the Boundary to gain the knowledge and power to save Lotte above. Gains telekinesis and the ability to tap into the power of the Boundrary, but is slowly developing memory loss symptoms and is in danger of turning into another Arakune.
** Hakumen[[spoiler:/Jin Kisaragi]]: [[spoiler:Jumps into the Cauldron after Ragna and Nu-13. Goes back 100 years in time, succumbs to injuries sustained prior to dive, but otherwise emerges unharmed - all mental damages relate to transfer to the Susano'o Unit shortly thereafter. Also engages Yuuki Terumi in a duel as a diversion so Jubei and Claudius Alucard can banish Terumi to the Boundary, [[HeroicSacrifice in the process sealing away Hakumen as well]]. Emerges 90 years later at 20% power, but has remained physically and mentally sound due to sheer force of will.]]
** Yuuki Terumi: [[spoiler:Banished to the Boundary during engagement with Hakumen. Lost the artificial body he was possessing at the time. Effects on mental state indeterminate due to prior batshit insanity.]]
** Relius Clover: [[spoiler:Enters the Cauldron for reasons unknown. Emerges 80 years later, physically unharmed; memories are jumbled during transfer, but are quickly reset to pre-jump state.]]
** Makoto Nanaya: [[spoiler:Loses her consciousness in proximity to Cauldron at Ibukido due to Prime Field Device activity and emerges in the ''Wheel of Fortune'' timeline. Travels back to ''Continuum Shift'' timeline with aid of Rachel Alucard. Zero physical and mental degradation in both transfers.]]
* ''[=BlazBlue's=]'' predecessor, ''VideoGame/GuiltyGear'', has the Backyard, a parallel world teeming with information which also serves as the source of magical energy for the world. Entry for most people into the Backyard is dangerous: without "tuning" to the Backyard's frequency, they risk being destroyed by the information inside it.
* Historia in ''VideoGame/RadiantHistoria'', [[spoiler:as well as Granorg's Royal Hall. Its final boss Apocrypha also looks something like this, albeit shrunk.]]
* ''Franchise/TheElderScrolls'':
** The series' universe itself. Starting with the AlienSky itself, the sun and stars are not typical balls of burning gas but holes punctured in reality by escaping spirits during the creation of Mundus, the mortal plane, and magic flows through them into Mundus which is visible in the night sky as nebulae. The [[WeirdMoon two moons]] of Nirn (the planet within Mundus that all of the action to date in the series' has taken place on) are said to be the rotting and sundered "flesh divinity" of Lorkhan (also known by [[IHaveManyNames other names]]), the [[TheMaker creator god]] of Mundus who was [[GodIsDead "killed"]] by the other spirits who aided in creation, now known as the [[OurGodsAreDifferent Aedra]]. The planets visible from Nirn are not typical planets, but are the planes and "flesh divinity" of the eight most significant of these Aedra. It is said that these forms all appear as they do because [[YouCannotGraspTheTrueForm it is the only way for a mortal's mind to comprehend it]]. That said, this information primarily comes from subjective in-universe sources who often conflict with each other, as the series is well-known for its [[UnreliableCanon intentionally contradictory lore]]. Just like many [[ScienceMarchesOn discredited beliefs]] in [[{{RealLife}} the real world]], the "true nature" of the TES universe could very much be as "normal"/conventional as our real universe is, or it could be something else entirely.
** The various planes of Oblivion, the "infinite void" surrounding Mundus, may be the [[GeniusLoci physical forms]] of the [[OurGodsAreDifferent Daedric Princes]] they are associated with. They are not bound to any of the laws of nature and physics that bind Mundus, and are subject to change on the whim of the associated Prince. Even [[YearInsideHourOutside time does not flow normally]] within Oblivion, though the exact details often vary. For example, when [[TheGoodKing Emperor Uriel Septim VII]] was imprisoned there by his EvilChancellor CourtMage Jagar Tharn for 10 Nirn years, he did not age a day. For specific details on the planes of the Daedric Princes, see the series' [[Characters/TheElderScrollsDaedra "Daedra" Characters]] sub-page.
** The island of Artaeum combines this with {{Bizarrchitecture}} and AlienGeometries. Artaeum is the home of the [[TheOrder Psijic Order]], a powerful MagicalSociety and the oldest monastic order in Tamriel. Artaeum shifts continuously either at random or by decree of the Psijiic Council. It can also be made to disappear ''entirely'' from Mundus.
** ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]''
*** In the ''Dawnguard'' DLC, you visit the [[SpiritWorld Soul Cairn]], a realm of Oblivion created by the Ideal Masters, a group of immortal beings who [[WasOnceAMan were once powerful mortal sorcerers]]. The Ideal Masters have a HorrorHunger for souls, especially the "Black" souls of sapient beings, and they [[YourSoulIsMine are always seeking to claim more]]. The Ideal Masters prefer [[EnergyBeing forms of pure energy]], as they find physical forms to be "too limiting". However, they will take the form of giant crystalline soul gems within the Soul Cairn, and can drain the souls of mortals who venture too close. Other Soul Cairn inhabitants include the captured souls [[FateWorseThanDeath doomed to spend eternity there]], grotesque undead monstrosities that randomly appear from the ground, and a {{Dracolich}} [[NinjaPirateZombieRobot zombie dragon necromancer]].
*** In the ''Dragonborn'' DLC, you visit Apocrypha, the realm of Hermaeus Mora, the Daedric Prince of Knowledge (with a particular specialty in [[TheseAreThingsManWasNotMeantToKnow Things Man Was Not Meant To Know]]. Reading one of Mora's "[[TomeOfEldritchLore Black Books]]" causes you to be ensnared by a tentacle that formed from letters which float off the pages, pulling you inside. The realm itself is a place Cthulhu would find comfy. All the walls are made of books, the water is slime and sprouts tentacles to attack you if you get too close, there are invisible monsters roaming the halls and sea mutants in the slime, certain areas have darkness that can kill you, and the architecture isn't necessarily static. On a more meta note, it also does not help that the area is notoriously [[GameBreakingBug glitchy]] so that when the when the layout of certain tunnels shifts, the Dovahkiin tends to clip and fall through the floors and walls into the deadly slime. But if you brave these horrors, the Black Books will grant you amazing powers.
* Astral Chaos in the ''VideoGame/SoulSeries'' is a timeless alternate dimension from which the Soul Swords originate, and is filled with lost souls and an EldritchAbomination or two.
* The Labyrinth of Deceit in ''VideoGame/KidIcarusUprising'' is a maze full of fake walls, holographic asteroid belts, gravity inversion switches, and disappearing paths. And even when you're not caught up in an illusion, the walls, ceilings, and floors are decorated... odd. And did we mention it's found inside a [[OurWormholesAreDifferent Space Rift]]?
** [[spoiler: And then Chapter 21 has the Chaos Vortex, which is basically the Labyrinth of Deceit taken UpToEleven. It contains replicas of ''every'' enemy from all four factions, [[LivingShadow living shadows]] that attack, eye-shaped portals that spring up out of nowhere, pieces of buildings that randomly move about, floating islands. It's just weird.]]
* ''VideoGame/Kirby64TheCrystalShards'' has [[spoiler:Dark Star, a planet made of [[EldritchAbomination Dark Matter]] and the {{Very Definitely Final Dungeon}}. Not much time is spent inside of it, but its red skies, ribbons of darkness and crystalline hexagonal tiles give it this vibe and make it significantly more alien than any of the planets visited in the game.]]
* Hang Castle in ''VideoGame/SonicHeroes'', but especially its interior, Mystic Mansion. In the daytime, it's a normal abandoned castle, albeit an exceptionally large one. At night, the exteriors seemingly extend endlessly in all directions, and gravity doesn't always point downwards. Once inside, rooms suddenly change topography (sometimes when Sonic and the others are in it), things pop in and out from impossible places, there seems to be a physical upside-down version of the mansion underneath the normal one, dumbwaiter tracks twist and contort while zooming off at high speeds, Eggman's robots pop up out of thin air (presumably intentionally), and what is supposed to be a well is full of weird vaguely water-like texture in all directions with a few small brick platforms suspended in it.
* The ''Franchise/TombRaider'' series has had a few of these, but two that stand out are the Atlantean Temple in the first game and ''[[VideoGame/TombRaider Anniversary]]'', and ''Tomb Raider II'''s Floating Islands level. In the first example, the deeper into the complex you go, the more organic the architecture gets, until the walls are made of pulsing muscles. The Floating Islands are...well, ExactlyWhatItSaysOnTheTin, a series of floating islands inside of a Chinese tomb.
* ''VideoGame/TheSecretWorld'' features several:
** One of the more benevolent examples arrives in the form of Agartha, a hollow Earth filled with branching trees, giant robotic caretakers, and a lot of bees, perpetually lit by sourceless golden light. It's actually a divine biocomputer and font of anima (i.e. magic), and it also functions as a weird PortalNetwork usable only by those touched by Agartha's bees (it "precipitates a messy discord" in the flesh of the uninitiated).
** On the other side of the metaphysical spectrum, places severely impacted by [[TheCorruption the Filth]] begin to corrode reality, opening starry portals to distant and lifeless space. One of the worst areas is "The Breach," an excavation site in Transylvania that's been converted into a massive wellspring of the Filth by the Orochi Group and the Vampire Army. We see another such location during the prologue, where Ground Zero for the Filth bomb detonated in the Tokyo subway has all but completely lost contact with reality. For the player, such locations are also a doorway to...
** ...the Dreaming Prison. A semi-metaphysical landscape of glittering black-sanded beaches under a midnight sky with a broken moon and blocks of white ice drifting overhead, dotted with massive cuboid shapes of an unknown material called the Gaia Engines. These things ''literally'' keep the world running, though Freddy Beaumont implies they can be used for "[[TakeOverTheWorld other things]]." For good measure, it's also a prison for the monstrous beings that produce the Filth, kept dormant by the Engines, and it's up to you to either reinforce the prison or help the inmates escape.
** The City of the Sun God. Built by Pharaoh Akhenaten in Egypt as an act of devotion to the Aten, it's on another Filth wellspring, and the results have turned into into a gathering point for just about any malevolent force in the area. The ''portals to {{Hell}}'' open in two corners of the valley don't help, but they're ''not the most eldritch things in the area''. The centerpiece of the alley is the Black Pyramid, Akehnaten's resting place. Thanks to a combination of arcane magic and the Filth's reality-warping influence, massive chambers and hallways fit inside despite clearly being too large for the structure. One of these rooms is a literally bottomless pit - above which the dormant [[HumanoidAbomination Akhenaten]] slumbers.
** In the update "The Vanishing of Tyler Freeborn", the Mist surrounding Solomon Island is revealed to be hiding one of these. [[spoiler:Specifically, the Red Sargassum Dream, a twisted recreation of the town of Kingsmouth under a perpetual midnight sky, inhabited only by Filth-infected versions of the locals.]]
** The Hell Dimensions are a FireAndBrimstoneHell that's almost completely starved of anima. The creatures inhabiting the place, identified in human folklore as demons, frequently try to steal anima from Earth, occasionally through [[HellOnEarth demonic invasions]] but more commonly by tempting humans into [[DealWithTheDevil signing over their souls]]. The environment in Hell is toxic to humans and capable of turning blood to metal, such that only those touched by Agartha's bees can survive down there. Theodore Wicker, a human mage interested in Hell, had to perform heavy magical alterations on his body (including tearing his heart out) in order to adapt to Hell's conditions, such that life on Earth became uncomfortable for him; he wound up leading a rebellion against [[{{Satan}} Eblis]].
* ''VideoGame/StarWarsTheOldRepublic'' has the Voss [[IDontLikeTheSoundOfThatPlace Nightmare Lands]], filled with barren soil, twisted trees, mutated wildlife, and a pervasive corruption field that reduces the weak of mind (read: everyone but the player characters) into violent psychopaths or blubbering vegetables. As an added bonus, there are no less than 5 quests available to deal with {{Eldritch Abomination}}s.
* The ''VideoGame/{{Thief}}'' series contains a few of these, notably Constantine's mansion, the Old Quarter and the Lost City in ''[[VideoGame/ThiefTheDarkProject The Dark Project]]'', and Shalebridge Cradle in ''[[VideoGame/ThiefDeadlyShadows Deadly Shadows]]''.
* ''Franchise/SuperMarioBros'':
** The level Matter Splatter Galaxy in ''VideoGame/SuperMarioGalaxy'', due to the unusual physics of the solid objects and grounds that only appear when a particular field of matter gets close enough. The green-colored background of the level is even more surreal.
** Compared to the rest of the DreamLand, Dream's Deep from ''VideoGame/MarioAndLuigiDreamTeam'' counts. While most of the other dream locations are more-or-less surreal versions of the area Luigi sleeps in, this place is implied to take on the appearance of the sleeper's subconcious. In this case, it's a large purple space with floating neon Luigi faces and holograms, with quotes representing his thoughts flying around. [[AlienGeometries There are places where going off on one end of the screen takes you to another location of another, and even how this works doesn't have to be constant. On the first visit, (the dreamed version of) Luigi goes missing until the boss fight, yet if you leave before said boss, he's back and claims that he was right behind Mario the entire time.]] And finally, the only "natural" inhabitants are Dark Blocks, [[SpritePolygonMix which are animated in actual 3D]] in contrast to game's "pseudo [=3D=]" sprites seen in the normal battle mode.
** The whole Violet Sector of ''VideoGame/PaperMarioColorSplash''. We have a sentient ocean, a whirlpool that never goes away, an area of the ocean that is pitch black in broad daylight, and smoke coming from out of nowhere. Except for the first thing, everything is a result of things going on in the Alternate World.
* In ''VideoGame/FarCry3'', it's implied that there is something subtly but fundamentally ''wrong'' with the Rook Islands. The extremely hostile animal life, the gradual madness that consumes anyone who goes into the jungle, the strange and mystical relics, the drugs giving accurate prophetic visions, [[spoiler: the ink demon]], and so on. It's not obvious, but the islands are ''doing things'' to the people who spend time there. However, due to the game's MaybeMagicMaybeMundane nature, it's left unanswered whether there is actually something wrong with the place, or if it's just the player character [[{{SanitySlippage}} losing his mind to drugs and trauma]].
* ''Videogame/KerbalSpaceProgram'' has Jool, which at first just looks like a green Jupiter. And then you get anywhere remotely close to it, and physics start getting more than a little odd, and only get nastier as your ship gets close, culminating in it spontaneously exploding while you're still several hundred miles from the surface. And then your poor astronauts fall in, and [[WreakingHavok their limbs]] [[BodyHorror flail in impossible ways]] before they simply die. And that's the ''best'' case scenario; there's the occasional tale of ships that survive entry getting flung out of the galaxy at FTL speeds. Of course, it's not actually meant to be that way - it's just glitchy as hell - but the fans have latched on to the first interpretation to match with a certain GoodBadBug being blamed on an EldritchAbomination. Funnily enough, it's this exact same weirdness that makes it completely immune to any and all attempts to (further) glitch it out, and not from lack of trying. And since many of those glitches tend to destroy entire planets...
* ''VideoGame/{{Dishonored}}'' has the aptly named Void, which consists of a series of islands floating in space, depicting fragments of real world buildings and characters frozen in time. It's the home of [[HumanoidAbomination the Outsider]], who will quite effortlessly and arbitrarily drag people there to mess with them or grant them magical powers or both, and it seems to bend to his whims.
* You've got your Shadow Lairs in ''Videogame/SpiralKnights'', but after the boss(es) are defeated, your team is whisked away to a frighteningly empty monochrome (especially compared to the colorful gameworld) tunnel called the Unknown Passage. Some really creepy ambience plays in the background as you prepare for a wave of enemies, and when they arrive, you'll fight TheSwarm.
* The [[OrphanageOfFear Edgewood Home for Lost Children]] in ''VideoGame/OurDarkerPurpose''. Inanimate objects come to often-malevolent life, the architecture shifts unpredictably, and the plants are twisted if not actively vicious. It's hinted that the lands outside the gate are ''even worse''.
* The ''VideoGame/MetroidPrimeTrilogy'' features a few planets that are more than a little twisted because of [[TheCorruption Phazon]] exposure.
** In ''VideoGame/MetroidPrime2Echoes'', Aether was split into two when it got hit by a Phazon meteor (which, in ''VideoGame/MetroidPrime3Corruption'', is revealed to be a Leviathan from planet Phaaze): the light world had some catastrophic global changes, such as plains becoming barren or a woodland jungle flooding but the serious issue was the creation of [[DarkWorld Dark Aether]] which has an atmosphere so toxic it kills any non native in seconds (eating through almost any sheilding), truly sinister landscapes and the locals are always chaotic evil and really don't like light.
** Phaaze, the Phazon planet, [[spoiler: by virtue of being a sentient being that is trying to spread and corrupt other planets]]. It also has some very organic looking natural structures. Lore surrounding the planet suggests that it's an EldritchAbomination existing in a higher dimension, with the planet merely being its form in our Universe. Phaaze is the source of all Phazon, which seems connected no matter how far apart its fragments are. Leviathans are birthed inside its crust, and Phazon versions of the Ing from the previous game appear as common enemies.
* ''{{VideoGame/Rift}}'' features the Planes of Water and Death. The first of these 2 Planes the Plane of Death appeared in the raid: Endless Eclipse and was not only a combination of bones and flesh yet most bizzarely the sky has an sun in an eclipse surrounded by Eldritch symbols.
** The Plane of Water is going to make it's debut in an upcoming expansion and it's first zone Goboro Reef is a sea with spaces of Water carved out of the zone due to the zone's creator waking up(the Plane of Water is actually a DreamLand) leaving walls of water rippling vertically around those waterless spaces.
** The Plane of Water's second zone Draumheim is a city with an ocean suspended over it(due to the inside of the city being effected by the aforementioned water being carved out of the Plane of Water) filled with every creature from everyone's dreams with the southern portion being a desert containing a forest and a bigger and nastier copy of Port Scion ruled by the Lord of Nightmares himself.
** The Plane of Water's third zone Tarkin Glacier is less of an EldritchLocation than the other two due to being a SlippySlideyIceWorld with the mountain at the end being filled with minature Air rifts with it's peaks being floating rocks which are the only Eldritch things about the zone despite the developers' claims of a heavy Lovecraftian influence.
* The ''VideoGame/DarkSouls'' franchise has a number of these:
** The Abyss could practically have a whole entry to itself:
*** The Abyss in New Londo. It's black. And that's pretty much it. No light. No landscape. No horizon. No ground. Just black in every direction, going on forever. You can only survive in the place by wearing a particular magic ring; if you don't, you just fall. Forever. [[spoiler:It was born out of concentrated human essence. That's right, apparently the source of this empty nothingness is ''humanity itself''.]]
*** The ''Artorias of the Abyss'' DLC takes you back to the Abyss, which is represented as an utterly lightless cavern filled with bizarre pitch-black ghosts that look like concentrated Humanity. The worst part is that the Abyss is clearly spreading outward, as strange blue-black ichor covers the surrounding landscape, getting more prevalent the closer to the Abyss one gets.
*** The Abyss is back in ''Dark Souls II'', now called the Dark Chasm of Old, where it can only be entered as a spirit, and contains spirits of other warriors endlessly wandering its cave-like halls killing anything they see, alongside these weird tree-sorcerer things. And the boss of the area is a creepy angelic being called the Darklurker, which absolutely nothing is known about.
** The Crystal Cavern. It's a huge cave that is home to bizarre monsters and invisible platforms. The sheer wrongness of the place seems to reflect the madness of the being who made the cave his sanctuary, Seath the Scaleless.
** Ash Lake. It's a small remnant of what the world looked like before the Fire and before the Lords defeated the Everlasting Dragons. It's a seemingly endless expanse of grey water, with gigantic, utterly massive trees extending up beyond the clouds that blanket the sky. All you find down here are a scarce few enemies, and even the small beach you explore is huge compared to most other areas in the game. The sheer scale, uniformity, and silence of the place, combined with the mournful music, just creates a feeling of emptiness.
** The Old Chaos in ''Crown of the Ivory King''. Beneath the frozen land of Eleum Loyce lies a giant inferno with tree roots branching all over the place yet not burning, and the battle takes place on an inexplicably floating stone platform far above an endless sea of flame, with doorways that contain fiery portals that spawn corrupted knights. [[spoiler:The roots and branches are meant to evoke Lost Izalith from the first game, where the Bed of Chaos was fought. It seems to be hinted that the Old Chaos is the Bed in a new form.]]
** The Untended Graves in the third game are a near-exact replica of [[spoiler:the tutorial area and Firelink Shrine... except crawling with much more powerful Undead, Black Knights, and covered in pitch darkness. One character's dialogue implies that the place is a look into an AlternateUniverse where the Fire has finally died and the Age of Dark has come. Since Firelink Shrine can only be accessed via bonfire-warping, while the Untended Graves can be reached on foot from the rest of the game, this has disturbing implications.]]
** The entire realm of Lothric is implied to be one in ''Dark Souls III'', as it's an amalgamation of different lands once ruled over by their respective Lords of Cinder, summoned across time. Even more so in the Kiln of the First Flame, which seems to be made up of an illogical jumble of buildings and architecture haphazardly piled on top of one another across an endless plain of ash and half-melted spires of rock.
* [[OurVampiresAreDifferent The Forest of Einnashe]] in ''Franchise/{{Nasuverse}}'', first mentioned in ''{{VisualNovel/Tsukihime}}''. It's a forest that acts like a vampire, in that it eats every person and animal that comes upon it. And yes, it can move and hunt ''cities'' on its own. Good thing it's only shown itself every 50 years.
* ''Franchise/{{Nasuverse}}'' also gives us [[MentalWorld Reality Marbles]]. It is a high-level magical barrier that forced reality around oneself to ''obey'' your vision of the world. As a result, it turns reality within one's proximity into one's own mental landscape, allowing them to use their ultimate techniques. These are traditionally possessed by [[EldritchAbomination Ultimate Ones]] and high-level spirits.
* The Red Night in ''VisualNovel/ElevenEyes''.
* ''VideoGame/{{Diablo}}'''s Tristram Cathedral definitely qualifies. It begins with ''mere'' demon infested crypts, and only gets worse from there. It's revealed that [[RealityWarper Diablo's mere presence]] is warping the lower floors into Hell.
* ''VideoGame/FlightRising'' has the Starfall Isles, the homeland of the Arcane Flight. The ''first sentence'' of its encyclopedia page describes it as "the twisted, broken islands of the Arcanist and his scholars" and it only gets creepier from there. Every part of the region, including the wildlife, is being mutated by the magical energy flowing through the area, from the mountains which have curved inwards, the shoreline that is now a glowing forest, and the formerly-low island which keeps growing higher. There's also the [[ExtraEyes eight-eyed]] hummingbirds, levitating pill bugs, and owlets that turn pink when they hatch at the Observatory...
* ''VisualNovel/{{Demonbane}}'':
** The first game's final battle took place in a succession of these taken from the ''Literature/CthulhuMythos'' itself, as the sheer power being exchanged between Demonbane and Liber Legis causes "dimensional quakes" that randomly throw them all over time and space. They visit, in order: the chaotic darkness of the Void Beyond, the Great Library of Celeano, a ruined Yaddith of the far future, a living asteroid field, Prehistoric Earth, the Darkness of N'Kai, and in a couple of routes finally end up on the dead world of Yith.
** The Shining Trapezohedron is ''itself'' an EldritchLocation, and sealed within it are [[spoiler:all of the evil gods that Demonbane could not kill, trapped within one universe and screaming to get out. Slashing something with the Trapezohedron sends it to that universe... where that thing will be at the [[FateWorseThanDeath mercy of all those extremely angry, immortal, evil beings.]]]]
** The sequel's villain turns Arkham City into an EldritchLocation, as it becomes a patchwork of different time periods, urban city and wilderness melting into each other, buildings that are upside-down and right-side up and everything in between, and time moves faster, slower, backwards, or not at all in various places.
* VideoGame/TheEvilWithin: The entire setting. What starts out as an odyssey into a zombie-infested county gives way to SchizoTech, frequently shifting landscapes, and a slew of {{Eldritch Abomination}}s. It's revealed two-thirds into the story that [[spoiler:Sebastian is inside a hive-mind controlled by an extremely deranged sociopath. Which explains the monsters and why he's able to upgrade himself and his weapons by injecting himself with brain fluid - the monsters are the manifested nightmares of the various minds inside a simulation, and injecting himself with the defeated brains represents taking control of the simulation]].
* ''Videogame/{{Bloodborne}}'': It's never quite clear where the normal places end and the stranger places begin, considering some of the weird stuff your character starts to find once you start acquiring Insight, but a few places stand out:
** Byrgenwerth College's Lecture Building, and the college in general, which [[spoiler:seems to have been dragged off screaming into the Nightmare realm, and while it still more or less looks normal, it's warped inhabitants (which include its old students turned into slime monstrosities) will quickly tell you otherwise. Oh, and it somehow hid an entire, endless lake of shimmering white in the moon's reflection in a small pool. And killing the entity you find there will quickly drag the whole town into madness]].
** Yahar'Gul, [[spoiler:a town within a town. Somehow, the entities in charge of the whole MindScrew managed to hide a large, nightmarish citadel that resembles an earthbound R'lyeh, within the small town of Yarnham. Most specifically, in one of the cathedrals]].
** And, of course, the Nightmare Frontier, [[spoiler:the Great Ones' actual realm, crawling with stuff that will destroy your sanity in seconds, and housing the nightmares of several important players in the whole scheme, in particular one that acts as a freaking EldritchAbomination ''nursery'']].
** In a way, the Hunter's Dream and possibly [[spoiler:''every single thing after the blood transfusion at the start of the game'']] counts. It's simultaneously AllJustADream and a real, actual place you can go to. And sometimes, for extra MindScrew, you can access the dream part and the real part separately, leading to oddities such as finding the long-dead corpses of people you met minutes ago. And while they seemingly don't affect each other, as the game goes, you learn that it most definitely ''does''.
** There's also the Nightmare of Mensis, what is essentially a giant castle in the middle of a mental dreamscape that houses multiple EldritchAbomination s and appears to be the headquarters of the School of Mensis, a faction of the game's CorruptChurch that wishes to contact the ''other'' {{Eldritch Abomination}}s.
** ''The Old Hunters'' introduces the Hunter's Nightmare, a twisted version of Yharnam (which is already twisted as it is) populated by AxCrazy Hunters who have been damned to this realm. There's so much carnage to be found, that a river of blood cuts through the city from thousands of mutilated corpses that turn out to be NotQuiteDead once you come close to them. And at the end, after traveling through the clocktower of a BedlamHouse, you come to the source of it all: [[spoiler:[[Literature/TheShadowOverInnsmouth a small fishing hamlet]] populated by FishPeople that's been dragged into a nightmare dreamt by the unholy spawn of a dead Great One.]]
* ''VideoGame/TheBindingOfIsaac'':
** A couple of late-game stages could count, but none, more than the stage accessed after killing Isaac's Mom: [[WombLevel The Womb]]. Despite the title giving you an idea of where you are, it's best not to think about it too much beyond that, as it's accessed through a fleshy hole in the floor after beating Mom, is a giant labyrinth of enemy-filled rooms (including Mom's sentient, severed hands in ''[[UpdatedRerelease Rebirth]]'',) and the final stage boss is Mom's ''heart''. Not to mention that there's a literally doorway to ''Hell'' (well, Sheol, but still) in there. And then there's the Scarred Womb in ''Afterbirth'', a variation of the previous dungeon that looks like [[{{Gorn}} someone took a chainsaw to the inside.]]
** The "I AM ERROR Room," a deeply-hidden area that can only be reached by through either random teleportation or, as of ''Afterbirth'', causing a paradox[[labelnote:As in...]]Using a Blank Card (an activated item that replicates the card held by the player) on a ? Card (a card that replicates the activated item held by the player) or using Teleport 2.0 (teleports to the next unexplored room) after exploring every possible room in the map[[/labelnote]]. It has a glitchy floor along a black void, an equally-glitchy shopkeeper with a word balloon reading "I AM ERROR," a direct way to the next floor, and a number of rather random possible items, pickups, or other objects. It cannot be escaped by anything other than teleportation and little to no real in-story reason for its existence.
** The VeryDefinitelyFinalDungeon in ''Afterbirth +'': the Void. The entrance appears at random after major boss fights (always after one particular boss), and appears to be a twisted black portal similar to those that have been spawning enemies. The floor itself is made up of a random assortment of rooms from all other floors, and occasionally is subject to bursts of static that alter the landscape entirely. It's also the only floor in the game to have multiple boss rooms, as many as ''eight'', and only one of them contains the actual boss. Which one it is is entirely random. [[spoiler:The Void and its boss Delirium are a representation of Isaac's mind breaking down as he suffocates to death. If he dies here, the game over screen refers to dying "In some dying memory".]]
* The eponymous dungeons from the ''VideoGame/PokemonMysteryDungeon'' series are explained in-story as this. In ''[[VideoGame/PokemonMysteryDungeonExplorers Explorers]]'', they're said to be the result of temporal and spatial distortions.
* ''VideoGame/MinecraftStoryMode'': The Farlands. Unlike Minecraft, where it was simply a glitch, here it's basically the literal edge of the world and an area of chaos incarnate.
* ''VideoGame/{{DownWell}}'': The Abyss
* ''VideoGame/CorpseParty'' features Heavenly Host Elementary School. It's a haunted, [[GeniusLoci sentient]], [[AlienGeometries multi-layered]] dimension that consists of just the rundown school (it was originally in the real world, but after a series of murders it was torn down) and a never-ending expanse of trees with ceaseless rainfall. Anyone who is unfortunate to be caught in it can and most likely ''will'' die from either hunger or starvation, vengeful spirits, or any number of creative traps [[ChaosArchitecture the school]] will lure the player into, all if the person doesn't commit suicide. Even worse, a person can succumb to the [[TheCorruption darkening]] the school exerts, become insane and contribute to the problem by killing their fellow members. Let's not forget that anyone who dies in the school not only experiences the pain and agony of their death ''forever'', but is also ''[[RetGone erased]] from existence'' in the real world.
** Made even worse with the reveal of [[spoiler:the GroundhogDayLoop and time travel]]. Just as space and planes of existence are warped in this dimension, so is the concept of [[spoiler:time and parallel timelines. It's told that even if you tried to save someone who died before, they will just [[YouCantFightFate die a far more gruesome death]]. Sachiko has mentioned that Yoshiki has died a few times in other timelines, which leads to [[FridgeHorror the realization]] that ''every possible timeline was exhausted'' and Yui, Morishige, Mayu, and Seiko always ended up dying in the school so it was impossible to ever save them.]]
* The ''VideoGame/TalesSeries'' has had its great shares of bizarre locations over the course of its many games, but one area in ''VideoGame/TalesOfVesperia'' is noteworthy: [[spoiler:the parallel dimension where the Adephagos is imprisoned, a ''planet-sized'' squid that sucks aer dry]].
** There's also Tarqaron, a massive floating city that was converted into a weapon to counter [[spoiler:the Adephagos]]. The inside has warped pathways and structures built in every which way, and the party debates on just "what the hell were the ancients thinking when they built this?"
** ''VideoGame/TalesOfZestiria'' has [[spoiler:Artorius' Throne, the final dungeon]]. It's a sealed section of Glenwood that contains a massive palace suspended over an empty void, with collapsed and broken pathways surrounding it leading in every which way. The sky is blood red and the sun is black, and the entire area is engulfed in malevolence. [[spoiler:Makes sense, since a hellonized Maotelus was sealed in there.]]
* In ''VideoGame/ShadowWarrior2'', the in-game justification for the game's ProceduralGeneration is that Earth's landscape is constantly in flux.
* In the ''VideoGame/AlanWake'' games, Cauldron Lake is home to a RealityWarper EldritchAbomination called the Dark Presence, that desires to enter into our world fully as a MonsterFromBeyondTheVeil. In service of its goal, proximity to the lake grants creative humans the power of RewritingReality, though the beneficiaries of this power, protagonist included, tend to exploit it to defy the Presence's will once they glean its malign nature. Cauldron Lake itself is far more [[BiggerOnTheInside deep and vast]] than it appears, as a deep sea fishing trawler has somehow found a way to its suspiciously oceanic depths.
* Indie horror game ''Kholat'' gives us ''[[https://en.wikipedia.org/wiki/Kholat_Syakhl Kholat Syakhl]]'', a.k.a. the ''"Dead mountain"'', a real-life place in northern Urals, Russia.
* ''Franchise/{{Halo}}'':
** [[SubspaceOrHyperspace Slipstream space]] is a set of eleven non-visible and highly radioactive "nondimensions" that has markedly different laws of physics and "topology" from normal space, with FTL travel requiring you to enter it. It was known for making some people disappear without a trace when it was first put to use, and for the longest time it was nearly impossible for the [[TheFederation UNSC]] to accurately plot courses within it at distances smaller than a planetary system, though the [[ScaryDogmaticAliens Covenant]] and [[ThePrecursors Forerunners]] had already mastered that part. These effects worsen as jumps are made further inside a gravity well.
** Additionally, slipspace travel inherently causes all sorts of chronological and causal paradoxes which the universe then has to "reconcile"; if too much FTL travel is happening at once, than slipspace will automatically slow down or halt all traffic within it until reality has finished reconciling itself, with the strange part being that this "reconciliation" affects events both forwards and ''backwards'' in time. Due to humanity's inferior understanding of this phenomenon, two of their ships traveling through slipspace together to the same place will often either exit slipspace at different times or, if they do exit at the same time, experience time with slipspace differently (to the point where one ship's clock might be an entire week ahead of the other's).
** The dimension encountered in ''Literature/HaloFirstStrike'' when the ship containing the main characters enters slipspace using a [[MacGuffin Forerunner crystal]] takes the weirdness [[UpToEleven a step further]]. Energy Projectiles would randomly teleport or follow random trajectories while kinetic weapons were unaffected, with the crystal itself emitting massive amounts of radiation, causing some... [[TimeyWimeyBall contradictions in the recorded timelines]], and [[ArsonMurderAndJaywalking allowing ships to travel much greater distances across space than usual]].
** According to ''Literature/TheForerunnerSaga'', Forerunners discovered a large variety of strange alternate realms, including one composed solely of photons.
** The Domain appears to be depicted in such a way in ''VideoGame/Halo5Guardians'', though no physics defying effects occurred. This makes sense, given that it was created by [[spoiler:the Precursors, who themselves were {{Eldritch Abomination}}s]].
* The upcoming video game ''VideoGame/LittleNightmares'' takes place in a place only known as the Maw, filled with giant monsters and seems to be a cross between a hotel and a steampunk nightmare.
* The Room in ''VideoGame/{{OFF}}''. The rest of the game is [[WidgetSeries bizarre,]] but internally consistent and stable, [[spoiler:if undergoing some sudden changes after being purified]]. The Room is a small area that the Batter goes through multiple times spread across different "chapters" in reverse chronological order. The place changes in each iteration, there's one section where the camera inverts for no explainable reason (and remains upside-down until after solving a puzzle), a portion where you're taken to a mock-up of the main menu and pick three different "save files," a gigantic NPC that wants to play a game where you tell him numbers that appear in other sections, and it includes a segment that appears like a child's crayon drawings. It's implied that the whole thing is ''some'' sort of flashback from [[spoiler:its guardian, a sickly boy seen briefly after beating the first two bosses]].
* The planet Mira in ''VideoGame/XenobladeChroniclesX'' is an unusual planet which is acknowledged by the Earthlings that crash land on it. It features a lot of different climates in close proximity to each other and is crawling incredibly hostile {{Eldritch Abomination}}s, and those are the normal parts. The weird parts are the how the planet does not appear on any star map, the way it draws different alien species to it and prevents them from leaving, the way it acts as a UniversalTranslator for the aliens, and [[spoiler: how it can keep sentient androids running without a power source.]]
* In both games in the ''{{VideoGame/Fairune}}'', the Secret File, a room based around either a desktop file system, an old RPG or a roguelike populated by unkillable Space Invader-styled bit monsters, is this. [[spoiler: In 1, these seem to bleed into the final dungeon, and in 2, this could count for both Ashen World and it's underground, Sky Land.]]
* In ''VideoGame/MapleStory'', there is Ludibrium. On the surface, it's a toy world BuiltWithLEGO, but as you dive deep into its towers, the LEGO walls grow thin, eventually giving you view of some outer-space vista which shouldn't have been possible. It doesn't help that that deep in the towers, you'll see lots of ghosts.
* ''Videogame/HelloNeighbor'': The Neighbor's house, which becomes even more twisted and nonsensical with every update. As of Alpha 4, making it far enough into the house reveals rooms leading to nowhere, a fully-operating train supported by nothing, winding hallways, and all sorts of additional physics-defying hazards.
* In ''Videogame/Metro2033'' and ''Videogame/MetroLastLight'', the nuclear war that wiped out human civilization on the surface also broke the barrier between heaven, hell, and reality. Throughout the series, there's a number of locations where they all blend together, some of which are benevolent, and others that are antagonist either through malice or [[PleaseDontLeaveMe their own isolated misery]]:
** In ''2033'', you can find the ghost of a ''subway train'' that endlessly moves across the tunnel before being crushed in a tunnel collapse. On the actual wreckage, ghosts sit on their morning commute.
** In ''Last Light'', the passenger plane that crashed into Moscow is haunted, and those that enter the cockpit see the plane's last moments as the disables plane plows into an apartment block being blown apart in nuclear fire.
** In ''Last Light'', there is a tunnel on the surface haunted by the corpses of the untold millions that died. Their ghostly arms try to grab anyone stepping through because they are lonely and afraid.
** The weirdest is The River of Fate in ''Last Light'', a GeniusLoci where the dead can place phone calls, skeletons stare you down as you pass by, oh and you can [[TimeTravel view the past with your buddies]].
* In ''Warframe'' there is the Void, a dimension that can only be accessed through special keys. The area appears as a vast expanse of space and pure energy, with only the occasional abandoned Orokin tower [[spoiler: or the moon]] floating in it's space. It is the source of all energy that the Tenno use and it has close ties to the lost god-like race of the Orokin. Occasionally fissures in space leak void energy and allow the Orokin towers to use their mind controlling power extend their reach. [[spoiler: General Vor was even able to become a pure godlike being of energy with the use of a special void key.]]
* ''VideoGame/{{Sundered}}'' takes place in a series of impossibly vast caverns deep beneath the earth, [[ChaosArchitecture whose layout and architecture change every time the protagonist dies]]. The environments within the caverns start out relatively mundane, but become progressively more bizarre and disturbing the further down you go:
** The Valkyrie Encampment seems fairly normal at first, being a lush, jungle-like region with strange rock formations and seemingly endless waterfalls in the background. Then you realize that the only living things in this area are strange metallic plants that can grow through metal, and hideous man-sized arthropods with electrical powers that throw themselves at the player character in suicidal swarms. And the robots that guard the abandoned Valkyrie military base have tumorous organic growths coming out of themÖ
** The Holy City of the Eschaton is located in a rocky cavern where the walls are covered in carvings of bones and alien eyes, geysers of purple energy erupt from the ceiling, stone stairways float in midair, dark tentacles occasionally form within the shadows (sometimes forming walls to block your passage), and towering structures and statues loom in the background. And thatís not getting into the masked, robed, shrieking monstrosities that call this place homeÖ
** The Cathedral is a gargantuan edifice where AlienGeometries are in full effect: pieces of the structure float in an endless void, giant fists made of tentacles will lash out at the player from patches of dark fog (which can appear out of nowhere), and glowing fungi will spew clouds of poisonous spores if you get too close.
* ''VideoGame/SpecOpsTheLine'' takes place in a version of UsefulNotes/{{Dubai}} that is subtly this trope. The city looks mostly normal enough, putting aside the battle damage and corpses scattered everywhere, or Walker's hallucinations where the sky catches fire and hellspawn claw out of the ground. But it's also surrounded by an impossible, continuous sandstorm cutting it off from the outside world, and riven with great unexplained chasms. More important is the fact that a level usually starts with Walker and his team repelling or zip-lining down from one skyscraper to another, descending deeper into the war-torn city... and then when the next stage starts, they're back in a high place, and have to go down once more.
* ''VideoGame/DarkestDungeon'' has the titular dungeon, a combination of WombLevel and AlienGeometries. Being in it is so [[GoMadFromTheRevelation stressful]] that heroes who go in their once will refuse to return.

[[folder:Web Comics]]
* Ravenfell in ''Webcomic/OverlordOfRavenfell'' is a sentient fortress made of black crystal, created through mysterious means. Beneath it is a magically shifting maze full of traps and monsters.
* The Corpse in ''Webcomic/CogaNito'' is a blue-tinted forest studded with random chunks of orange machinery, so named because neither the trees are alive nor the machinery functioning.
* ''WebComic/{{Homestuck}}'':
** The Furthest Ring, a PlaceBeyondTime which is the home of the [[EldritchAbomination Horrorterrors]], the Green Sun (a star with the mass of two universes, which breaks several laws of physics), and the afterlife (which exists as a series of Dream Bubbles). It is said that if one were to draw an accurate map of the place, the result would be a page completely and uniformly covered in black. Time and space behave in incomprehensible ways in the Furthest Ring, and both become less reliable the longer you stay (or the further you go). For example, when Dave and Rose try to fly out to the Green Sun, [[spoiler:they end up arriving in the distant past]].
** Dream Bubbles themselves may count, as within them the conventional laws of time and space don't apply, as one can warp from memory to memory, effectively traveling forward and back in time and anywhere in space. Locations can even converge in such a way that they're a mis-match of memories of the various dreamers/dead people. For example, in one there was a mixture between Jade's island, Kanaya's home, a ruin Aradia was exploring, and some other elements.
* ''Webcomic/SluggyFreelance'' has plenty. The alternative dimensions vary from almost identical to the "normal" one to as bizarre as you like. One example: The Never is a hellish world where spirits become solid and living creatures become even more so than usual. Other Eldritch Locations can be found without even travelling between dimensions. Each dimension is surrounded by Timeless Space, where time is only carried by objects and creatures and will eventually run out for each of them, freezing it in place. The two [[TomeOfEldritchLore Tomes of Eldritch Lore]] ''Book of E-Ville'' and ''Wayang Kulit'' each contain or give access into a different kind of symbolic nightmarish world that builds itself around the thoughts of an entering character.
* The Palm Tree Ghost's realm is turning out to be [[http://danielscreations.com/ola/comics/ep0296.html more and more this way]] in ''Webcomic/OurLittleAdventure''.
* Webcomic/TalesOfTheQuestor has the Unseleighe castle of Princeling Dolan in Tir Na Nogh. Simply navigating the halls can make you arf your cookies.
* In ''Webcomic/MetroidThirdDerivative'', Planet Nemesis as named by Samus. She identified it at the source of all Phazon with the core of the planet being pure Phazon while the atmosphere and various landmasses that float above it having heavy concentrations of Phazon. A ring of Phazon meteors circle the planet destined to be thrown into space and affect other planets. Lifeforms not resistant to Phazon will die quickly on Nemesis.
* The forest in ''Webcomic/LucidSpring'' transforms into this whenever Viktor and Pacem's [[http://lucidspring.thecomicseries.com/comics/36 hallucinations]] [[http://lucidspring.thecomicseries.com/comics/37 are seen.]] The world takes on a red tint, Viktor and Pacem have wounds they don't really have, and trees ''bleed.''
* Often PlayedForLaughs in ''Webcomic/{{Nedroid}}'', including [[http://nedroid.com/2010/07/ask-your-travel-agent/ the Magma Zone]] and in [[http://nedroid.com/2009/10/fall-foliage/ this]] strip.
-->'''Reginald:''' Autumn is [[DissonantSerenity especially beautiful]] here in the Nightmare Zone.
-->'''Beartato:''' My heart is screaming with joy.
* ''Webcomic/ZebraGirl'': Sandra's house. It began to change when Sandra transformed into a demon, with shadows becoming darker and bigger, and decided to have a growth spurt on its own while Sandra was away.
[[/folder]]

[[folder:Web Original]]
* Many Wiki/{{SCP|Foundation}}s are {{Eldritch Location}}s. Some of them also qualify as {{Eldritch Abomination}}s since they are ''[[GeniusLoci alive]]''. There's also [[http://scp-wiki.wikidot.com/scp-093 the "Red Sea Object"]], which takes people into an alternate universe where [[spoiler:"a god-like being of unknown origin" instigated a massive holy war hundreds of years ago, with apocalyptic results, and now giant, immortal UncannyValley monsters roam the land, absorbing anyone who catches their attention]].
** According to [[http://www.scp-wiki.net/exploratory-mission-354-alpha this tale]], [[http://www.scp-wiki.net/scp-354 SCP-354]] leads to a world like this. Days last 43 1/2 hours, the sun is bright red, and the laws of physics don't seem to be consistent. Compasses shift daily and liquid water exists alongside liquid carbon dioxide. And there's also [[spoiler: the heavy implication that the world can erase people from existence.]]
* ''WebAnimation/HomestarRunner'':
** [[http://www.homestarrunner.com/sbemail174.html Sweet Puttin' Cakes]], a miniature golf course "every bit as messed up as the cartoon on which it's based." Residents of Free Country, USA find themselves inexplicably teleported there simply by desiring to play miniature golf. The first hole is the [[VisualPun "worm"hole]], the 18th hole has par infinity, and the only way to leave is to will yourself back to reality. When Strong Bad returns, he remarks that his mouth "[[TastesLikePurple tastes like backwards]]."
** We could go ahead and classify the Sweet Cuppin' Cakes world (which is apparently a real location) as an Eldritch Location. Just think of the inhabitants! A Strong Bad with a keyboard head, a black-and-white-talking wheelchair, a talking worm in a hole that appears to be able to warp from place to place. There's also the fact that characters can come from nowhere and that everything appears to be able to utilize hammerspace.
* ''Roleplay/RubyQuest'':
** Cold Storage.
** Much of the whole facility, really. Especially the brig, with that growing dark pit and half of its gravity reversed.
* Brian's house in ''WebVideo/MarbleHornets'' became this, thanks to [[Franchise/TheSlenderManMythos a certain someone]]. It doesn't fully follow the laws of reality and is connected to a burnt-out, industrial-looking building that is laden with even more horror.
* Sarah Waite's (yes, the last name is meaningful) dorm room at [[SuperheroSchool Whateley Academy]] in the Literature/WhateleyUniverse. It's even ''called'' the Lovecraft Room.
* WebVideo/NyxCrossing, a mysterious area that centers around a section of railroad track. According to the natives, "There is no distance," and there is a mysterious monster that stalks the characters.
* The [[http://bogleech.tumblr.com/post/74701719961/i-know-that-the-noisy-tenant-universe-the-one-where Noisy Tenant Creepypasta mythos]] is very much set in this this, given that in the core premise is that people suddenly wake up, out of nowhere, in the titular building, an endless place where space [[spoiler: and time, if the ending to Dr. Phage's Hospital is any indication]] doesn't work the same as in our reality and where there's been no exit shown in-setting.
** The place itself can be described as what would happen if Franchise/SilentHill were designed by Creator/SidAndMartyKrofftProductions , with whimsical inhabitants (An anthropomorphic hamburger chef made of rotting meat and a man-sized bacteriopage doctor with glasses and a bow-tie being the most prominent) who do horrible; horrible things to the people stuck in their realms...
** And, as a bonus, [[Website/{{Bogleech}} the creator]] has said that it's not anything as banal as another planet or another dimension, but rather something humankind has no context whatsoever for. He compared trying to explain the reason why it exists to explaining to a Pilgrim the concept of a WebAnimation/YouTubePoop without explaining computers, videos or electricity.
* ''Franchise/TheFearMythos'' has the Empty City: a possibly [[EldritchAbomination living]] city located in an alternate dimension. The city is ''huge'', changes every time you turn a corner, and is completely devoid of all souls.
* In ''Literature/TheDionaeaHouse'', the titular "dionaea house".
* Parodied in LetsPlay/ChipCheezum's LetsPlay of ''VideoGame/FiftyCentBloodOnTheSand'' with the "Fiddy Zone", a glitch where background textures fail to load during a [[ActionCommands Counter Kill]], leaving Fiddy and his opponent in a void covered by film grain.
%%* Wherever the hell it is that the WebAnimation/HappyTreeFriends universe takes place in.
* in ''Webcomic/DemonThesis'', the four main characters attend a small liberal arts college in Canada, when a [[ManipulativeBastard manipulative entity]] from another dimension begins altering reality. Only afterward do the main characters learn that their school was originally founded by an occultist who knew that the location was a place where our dimension was unusually close to and could interact with other dimensions. Said occultist intended the university to inform about the dangers of this and form a line of defense against threats, but over time the school transformed into a fairly normal university and most occult/supernatural elements have been discarded.
* ''WebVideo/CollegeSaga'' has the Cursed Structure (i.e. Babson College's Fountain of Flags). As long as it exists, mankind will continue eating vegetables.
* Prominently featured in [[http://wanderers-library.wikidot.com/the-tomb-war The Tomb War]] from ''Wiki/TheWanderersLibrary''.
* ''Literature/TheSickLand'' revolves around such a location. The titular Sick Land is a massive patch of land where strange plant life grows; people and animals that stay there for too long suffered bizarre, incurable, and fatal mutations and sickness. [[spoiler: Later it's revealed to be ''spreading'' at a slow rate, corrupting the land around it.]]
* ''Podcast/WelcomeToNightVale'', where everything paranormal is true.
* The Fineum Cuniculum from Wiki/TheWorldbuildProject probably qualifies. No one knows how it got there? Check. Mysterious engraving all down the walls of a three kilometer tunnel? Check. People randomly disappearing? Check.
* In ''Podcast/AliceIsntDead'', a long haul trucker {{Narrator}} keeps encountering paranormal places in the course of her work, from an EvilTowerOfOminousness looming in the distance to Charlatan, a traveling VanishingVillage trapped in a GroundhogDayLoop that repeatedly violates the laws of physics in increasingly disturbing ways every time she passes through.
* ''WebOriginal/ProtectorsOfThePlotContinuum'' has Headquarters, an unimaginably huge building located in the space between worlds that the PPC calls home. It's constructed from {{metafiction}}al materials like {{Plot Hole}}s and "concrit" ([[{{Pun}} concrete made from constructive criticism]]) and a portal to it exists in one specific location in each world of TheMultiverse, usually an extremely innocuous one nobody would check if they weren't specifically looking for it. Its most famous feature is that, as a defense against MarySue attacks, it's impossible to ''intentionally'' find your destination within it; PPC agents are well trained to "switch off" their minds whilst trying to get from one part of the building to another, something the simple brains of Sues are incapable of. A RunningGag in the stories is that it supposedly has a pool, but nobody, whether intentionally or not, has ever been able to find it.
* ''Literature/GreenAntarctica'': The glacier at the center of the continent is seen as one by the Tsalal, one so evil that they refuse to give it a name. While their entire culture [[SnowMeansDeath fears the color white]], it goes beyond just that. The glacier is the size of a country and half a mile thick. The dry, chilled air above it is unnaturally lit by the sun and carries sounds differently, giving it the feeling that reality is warped by its very presence. The entire thing moans and creaks as fissures open up and water erupts outward. Its edges expand and retreat like the pseudopods of a vast amoeba. There are times when the winds will trigger a sudden torrent of frigid air that splashes outward and kills everything in its path. The Tsalal cultures alternatively view it as the source of all death and suffering, hell, the abode of the gods, or even a sleeping god itself. What they can all agree on is that, when it awakens, it will bring about the end of all worlds.
[[/folder]]

[[folder:WebVideo]]
* The second chapter of [[WebVideo/MLPAnalysis Dr. Wolf's]] OriginEpisode takes place in such a place that takes the form of a library in the middle of a vast desert. Time doesn't move in the library, as Wolf doesn't age or require food, water, or rest the entire time he's there. The structure goes on forever in any direction, smells do not grow stronger or weaker anywhere or at any time, and Wolf always sensed a feeling of intrusion, as if the library sensed he and his master didn't belong and desired to expell or assimilate them.
* ''WebVideo/CarmillaTheSeries'' has the library. While more or less the entire campus is [[ExtranormalInstitute weird]], the library is above and beyond anything there, described as a sentient Escher painting with shelves and a force to be reckoned with against even the most powerful beings of the series. It stuck someone into a computer system before computers were even invented, has portals [[NotHyperbole literally]] everywhere, and a personality that ranges from [[PokeThePoodle comedically annoying]] to outright terrifying when enraged.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/JackieChanAdventures'' has the [[PrisonDimension Netherworld]], a dimension that the [[OurDemonsAreDifferent Demon]] [[EvilSorcerer Sorcerers]] were banished to by the [[Myth/ChineseMythology Eight Immortals]]. The Netherworld is a seemingly infinite void filled with floating rocks, which condemns [[SorcerousOverlord the]] [[DemonLordsAndArchdevils Demons]] to an eternity of boredom.
* The Spirit World in ''WesternAnimation/AvatarTheLastAirbender''. Shown in more detail in ''WesternAnimation/TheLegendOfKorra'', as we see such thing as [[FisherKing the terrain and inhabitants being affected by the emotions of humans inside of it]], [[GravityScrew gravity not going in any particular direction]], and [[AlienGeometry conventional concepts of location and distance being violated.]]
* The Ghost Zone in ''WesternAnimation/DannyPhantom'' which serves as an "opposite" dimension to Earth. Home to ghosts, it's a massive world where its sky is a swirl of eerie green and black. Surrounding the majority of the GZ are (usually small) floating lands--it's rare to find giant land masses since ghosts don't really need to walk--and multiple floating doors that lead to various ghostly realms, all unique, surreal, and different based on how it fits the ghostly inhabitants.
** Those large landmasses include a giant prison, an island that's the home base of an EgomaniacHunter, and the ''temple of Pandora''.
* ''WesternAnimation/SouthPark'':
** The evil half of Imaginationland. They never allow anyone or anything good to cross into their territory or else they'll be killed. Otherwise, they have no interest in war, [[PretextForWar until the terrorists attacked both halves of Imaginationland and pinned attacks on the Evil territory on the Good Imaginary Characters.]]
** The Dark Oblivion, also known as the Sunken City of R'lyeh in Coon 2 literally personifies this trope, as it is supposed to be Cthulhu's home plane.
* Possibly the emperor's palace in ''WesternAnimation/XiaolinShowdown'' as it is one of the only places where, if a Showdown is declared, the participant's clothing does ''not'' change. While this could be written off as for sake of plot (Kimiko's formal but awkward kimono made it more of a challenge for her to overcome) [[FridgeLogic it makes sense]] if you consider the societal rules of etiquette of such a place; the palace emits a spiritual counter spell to prevent other sources of magic to break such taboos.
* Although it's much more light-hearted than most, Wacky Land in ''WesternAnimation/TinyToonAdventures'' probably qualifies. The original Wacky Land, however, featured in at least one Looney Toon short and its color remake, varies from merely inexplicable to subtly menacing in its bizarreness.
* The Web in ''WesternAnimation/ReBoot''. Dark and organic looking in comparison to The Net's bright technological look.
* ''WesternAnimation/SpongeBobSquarePants'' gives us "The Fly of Despair" from "Shangheid", a dimension that only the Flying Dutchman and Squidward know about which is nothing but a dark tunnel of surreal, demonic imagery.
* ''WesternAnimation/TheRealGhostbusters''[=/=]''WesternAnimation/ExtremeGhostbusters'' made regular use of these. From the Bogeyman's home dimension to a sneak peek at the end of the world to a ghostly pirate TV station, the series enjoyed dropping the Ghostbusters in places where physics didn't work right and the architect expected the residents to be capable of phasing through walls. Some examples:
** New York in general seems to be this in their universe, it is constantly attacked by all sorts of spirits, monsters, demons, LegionsOfHell and interidmensional creatures.
** The Containment Unity evolved into this after a while. How exactly become BiggerOnTheInside is never explained but it seems to be its own immense PocketDimension, very similar in look to the Netherworld.
** The Neterworld which is basically AnotherDimension from where ghosts are original. Winstons describes it as a place full of spirits, demons and souls of people that couldnít reach other realms. The look of it varies from episode to episode (justified as itís said by Ray that it has the size of our universe) but itís mostly shown as a huge wasteland with floating boulders and mist.
** The cabinet dimension: a dimension connected to our world from a magicians cabinet is pretty much a [[FireAndBrimstoneHell hell dimension with boiling lava and snakes raining from the sky]].
* ''WesternAnimation/TheSimpsons'':
** Springfield could very well count at this point. One look at the JustForFun/SeparateSimpsonsGeographyThing page should tell you all you need to know.
** The occasionally mentioned "Springfield Mystery Spot". It's unclear if Ozzy Smith was ever seen again
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** [[PlayingWithATrope It plays with this]] via the Everfree Forest. While home to an assortment of beastly critters -- like manticores, sea serpents and cockatrices -- and weather that is consistently "dark and stormy", the ponies also regard it as horrific and unnatural because ''everything there takes care of itself''. The plants grow on their own, the animals don't need to be looked after, the weather runs without help... it's '''surreal'''! ([[PaintingTheFrostOnWindows From their point of view, anyway.]])
** Played straight in the season 2 premiere with Discord's hedge maze, which could be best described as [[Creator/MCEscher Escherian]] shrubbery. Not really a surprise when the architect is a [[RealityWarper Reality Warping]] spirit of chaos. In the second episode he turns all of Ponyville into this, [[WorldGoneMad and drives its inhabitants insane for good measure]].
** We get to follow Discord home in season five. It's a PocketDimension that does ''not'' disappoint in terms of WorldGoneMad. As such... [[UnstoppableMailman the mail is sometimes delivered *slightly* late]].
** In ''WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames'', the Twilight Sparkle who originates from the human world briefly stumbles into [[spoiler:the pony world]] [[GoMadFromTheRevelation and returns completely insane]], hinting that to regular humans, [[spoiler:the pony world itself]] is an Eldritch location.
* ''WesternAnimation/{{Superjail}}'' is full of these, especially within Superjail itself, but the [[TimePolice Time Court and Time Jail]] in "Time Police" take the cake. Considering it's a place where all living beings from all corners of the universe and time work or are tried and imprisoned, this is to be expected.
* A ''WesternAnimation/FamilyGuy'' skit shows Peter going into the 'beyond' section of 'Bed, Bath, and Beyond' which is a black void filled with various floating formulas and the like...and the coffee mugs he was looking for.
* [[WesternAnimation/InvaderZim A room with a moose. A dimension of pure dookie.]]
* ''WesternAnimation/AdventureTime'':
** The Nightosphere, home loads of creepy demons and is essentially Hell.
** The rest of the land of Ooo is pretty weird too. There's a kingdom ''made of candy'' that is ''populated by candy''.
* ''WesternAnimation/CourageTheCowardlyDog'': Nowhere, Kansas. It looks like a desert wasteland where strange monsters show up for no real reason at all. [[StealthPun And the main cast lives in the middle of it.]]
* ''WesternAnimation/RegularShow'' the park is constantly swarming with weird people, bizarre creatures, and EldritchAbomination that appear by ripping of the very fabric of reality.
* ''WesternAnimation/GravityFalls'' is a magnet for all sorts of bizarre people, creatures and entities, including a clan of macho minotaurs, a bear with more than a dozen heads, and a walking mass of rejected Halloween candy. There's also a LostWorld in the caves beneath the town, complete with still-living dinosaurs [[HumanPopsicle encased in tree-sap]].
** [[spoiler: There's also the Nightmare Realm. A decaying dimension that is the home of several interdimensional criminals and nightmares, all of which are leaked into the titular town in Weirdmagedon by Bill Cipher.]]
* Elmore from WesternAnimation/TheAmazingWorldOfGumball definitely counts, considering [[spoiler: the entire plot of an episode involves a black void where the town dumps all its mistakes.]] In fact, the aforementioned [[spoiler: black void]] counts, what with [[spoiler: its alien geometry, and how the current BigBad was permanently scarred upon exit.]]
* Many locations in ''WesternAnimation/StevenUniverse'' are peculiar or exceptional (such as the pyramid from ''Serious Steven'' or the Lunar Sea Spire in ''Cheeseburger Backpack''), but the inside of the Gem Temple easily takes the cake as one of the weirder and more frequently seen locations. The main door opens up to different locations depending on who operates it, it has multiple organs including a colossal pulsating heart, and there are corridors that twist on themselves while still maintaining a nebulous sense of gravity... to say nothing of the personalized rooms each of the gems have:
** Pearl's room is a series of freestanding waterfalls which she [[WalkOnWater stands atop]] and keeps objects inside the water. It also features what looks to be a starry sky overhead, completely ignoring the fact that this is supposed to be indoors. Further down, the waterfalls flow sideways and even upwards.
** Amethyst's room is a section of shallow purple coastline below Pearl's, littered with an assortment of objects including a palm tree and piles of gold coins. Huge crystals grow out of the walls and floor. Said coast is littered with puddles where, if you submerge yourself on one side, you emerge from the ceiling or floor of a different room.
** Garnet's room is a low, circular area floored in stone. Unlike the others it actually seems like it could feasibly be inside, but the ''veins'' of the temple feed into the walls on all sides and the ceiling is filled with bubbled gems. There's also a pit of exposed lava in the center [[KillItWithFire which sees occasional use]].
** Rose's room is a huge expanse of sparkling pink clouds that has this little thing of recreating anything its occupants ask for out of said clouds. It also operates like a computer simulation and [[OminousVisualGlitch crashes]] if asked to create anything too grandiose.
*** There's also the inside of Lion's mane, a PocketDimension that could be best described as an airless, Pink version of The Moon from Majora's Mask. It contains several things that were important to Rose, such as one of Greg's t-shirts, her sword, a video for Steven, and, formerly, [[spoiler: a bubble containing Bismuth's gem.]]
** Sardonyx's room, a black expanse that looks similar to a talk show room complete with an unseen audience, which Sardonyx can manipulate however she wants. It also only exists when Pearl and Garnet are fused as Sardonyx.
* In an episode of ''WesternAnimation/TheNewMrPeabodyAndShermanShow'' the show gets consumed by a black hole. Mr. Peabody keeps hosting from inside, a bizarre space where the rules of physics do not apply and anyone can become anything.
* In ''WesternAnimation/InfinityTrain'', a girl named Tulip is stuck on a seemingly endless train in the middle of nowhere. Tulip has spent a week traversing the cars to no avail. The train seemingly has no end, it possesses creatures which defy logic, and the cars themselves have properties which don't fit their external design. The train does have a front end, as seen in the opening, but would have to be impossibly long for Tulip to have spent as long as she has moving through cars.

* The [[EldritchLocation page quote]] from ''Zauriel'', above, well describes the [[http://en.wikipedia.org/wiki/Photosphere surface of the sun]]. The innards of a star, the depths of a [[http://en.wikipedia.org/wiki/Gas_giant gas giant]] and the vacuum of [[http://en.wikipedia.org/wiki/Outer_space deep space]] all feature mechanical properties that are incomprehensibly alien in comparison to the natural laws as we know them. Small and frail is the magical bubble in which we live and thrive.
** We can do better than that: Black holes! Also, Calabi-Yau space, the universe before the Big Bang, and pretty much anything beyond the universe. And the inside of an atom. Actually, the modern understanding of physics pretty much [[ThisIsYourPremiseOnDrugs requires a lot of drugs to understand]].
** Some of these have since put to contest - for example, the quantum physics as we know it doesn't allow an absolute singularity to form, even though General Relativity does, which may mean that no "true" black holes exist, whereas other theories challenge the idea of the Big Bang as the start of the Universe - it has already been all but disproved in the form it's being taught in schoolbooks, but the event's exact nature still eludes the scientists, and there are multiple conflicting theories without enough evidence to pick one over the others.
** Understanding the singularity that was the entire universe could require a higher level of maths than we have so far. [[http://io9.com/?_escaped_fragment_=5773158/what-really-happened-right-after-the-big-bang#!5773158/what-really-happened-right-after-the-big-bang Considering that the physics at the literal instant after the expansion began were so much different than what's in the universe now, it's not hard to conceive that.]]
** Black holes aside, neutron stars also qualify. They are so far removed from our everyday life that they are basically incomprehensible to the human mind. Their surface is so smooth that a mirror is a mountain range in comparison, and so dense and hard that a diamond is like the vacuum of outer space in comparison. The surface gravity is so strong that it very visibly bends light, and any matter will get crushed into it so hard that even its constituent particles will break and fuse into neutrons. The whole star has a mass of tens of suns and can rotate even at over a thousand revolutions per second. Because of this incomprehensibly rapid rotation speed, the star is actually a spheroid instead of a pure sphere, regardless of its density: That's how fast it rotates. And when the rotation slows down over time due to loss of energy, an unstoppable force (gravity) will acting on an immovable object (the surface of the star)... When the rotation speed has slowed down enough, the surface will give way and the ''entire'' star will restructure as a slightly less elongated spheroid... an event that's so immensely powerful that it emits an incredible amount of energy to outer space as a big flash.
** The spacetime inside of a black hole is one of the most alien regions we have yet speculated. While black holes do not "suck" things in, past the event horizon the gravity from the singularity has distorted space time so much that all paths lead deeper into the black hole. This is why light cannot escape a black hole, not because the escape velocity would exceed the speed of light, but because there is literally no path out, only deeper.
* Singularities in general are this in whatever system they might manifest in. Simply, a "singularity" is an instance in a system where the normal rules of the system are inapplicable.
* Planets with high gravity or atmospheric pressure can make for some extremely odd locations. There is one exoplanet for example that the scientists believe to be covered in boiling hot ice due to such conditions.
* Our planet itself has one in the form of the ocean, especially deep down in the trenches.
** Creatures born without what we would see as vital to living, pillars of sulfur belch toxic superheated smoke, the pressure so intense even thick steel can be crushed easily; and that's just scraping the surface of what's down there. Supposedly, there's more undiscovered species down there than there are extinct species.
** [[http://en.wikipedia.org/wiki/Undersea_lake Brine lakes]]. They are, for all intents and purposes, lakes under the ocean, complete with a shoreline. Even more [[MindScrew mind screw-y]], the density of the brine lake's surface means that any submarine that visits it can "float" on top of the denser brine lake surface. While already underwater. That's right, scientists found [[WesternAnimation/SpongeBobSquarePants Goo Lagoon]]!
** There is also the phenomenon of [[https://en.wikipedia.org/wiki/Deep-sea_gigantism deep-sea gigantism]], as well. For unknown reasons, with theories ranging from greater energy conservation, to protection against the pressure and cold of the deep sea, several animal species grow several times larger than relative species in other parts of the ocean. Such creatures include [[https://en.wikipedia.org/wiki/Giant_isopod giant isopods]], ''[[https://en.wikipedia.org/wiki/Alicella Alicella]]'', [[https://en.wikipedia.org/wiki/Japanese_spider_crab the Japanese spider crab]] and various forms of giant mollusk, such as the [[https://en.wikipedia.org/wiki/Seven-arm_octopus seven-arm octopus]] and the [[https://en.wikipedia.org/wiki/Giant_squid giant squid]]. While many of these creatures are more or less larger versions of animals found elsewhere, it only adds to the strangeness of the abyssal ocean.
* Conceptualizing how the world appears to animals with radically-different BizarreAlienSenses -- echolocation, electroreception, vibratory sense, etc -- can reveal how different even an ordinary room must seem to them.
** Any species that can perceive radio signals as sound or sight would be driven blind or deaf immediately, if not completely insane.
** Imagine getting trapped in a strange dimension where dozens or even hundreds of suns blink in and out seemingly at random, populated by [[HumansAreCthulhu titanic monsters that will brutally crush you for merely annoying them with your existence whenever you stop to take a rest.]] This could very well be how a flying insect experiences a building they have flown into.
** The universe of the fairy fly. Air is an all-encompassing jelly that it has to grab onto to fly.
* Antarctica. So many things make this place this. From four month summers and four month winters, places that look similar to Mars, hurricane winds that constantly happen with category 5 winds happening once every winter, green lights constantly appearing, it is one weird place.
** And that is not even touching on what may be preserved under the ice...
* The [[https://en.wikipedia.org/wiki/Darvaza_gas_crater Darvaza gas crater.]] Geologists broke through to a huge gas cavern, decided it was too dangerous, set it on fire, and left it burning for over ''40 years.'' It's literally called the ''gate to hell.''
