History EldritchAbomination / Literature

* ''Franchise/HarryPotter'': The Dementors, the guards of Azkaban; ghastly and unnatural even by the standards of the wizarding world, they feed off of joy and can suck the soul right out of your body, and there is no explanation as to exactly what the hell they are. Even ''{{Muggles}}'' can feel their presence, though they [[InvisibleToNormals can't see them]], and merely being in their presence can fill humans with despair as all the happiness is leeched out of their bodies from these monsters. They can even affect the weather, as Cornelius Fudge explains the vast fog that being covering London is because ''they're breeding''. Harry muses that the reason why his Godfather Sirus Black (escaped convict) is hiding out in the tropics is because Dementors [[WeakenedByTheLight wouldn't last]] long in sunny areas. The only way wizards have to combat them at all is a defensive spell that drives them away (but doesn't actually harm them), which is apparently very difficult to preform. And of course they're [[ImmortalityImmorality immortal]].

* ''The Skin Trade'' by Creator/GeorgeRRMartin has the demonic Skinner. Skinner isn't a typical BigRedDevil, it's a legendary abomination living in mirrors and can travel through them to [[HuntingTheMostDangerousGame hunt and skin werewolves]] with its claws made of silver.

* ''Franchise/StarWarsExpandedUniverse'': ''[[Franchise/StarWarsTheHighRepublic The High Republic]]'' sub-franchise gives us the Nameless]], first introduced in ''[[Literature/StarWarsTheRisingStorm The Rising Storm]]'' via a creature known to Marchion Ro and the Nihil as "the Great Leveler". Not only was the Leveler [[SealedEvilInACan sealed away in high security]] by Marchion's ancestors, these creatures are capable of attacking Jedi through the Force. Their mere [[BrownNoteBeing presence]] can cause [[MindRape fear-heightening hallucinations]] in Jedi (obscuring what the creatures look like to them), can cut Jedi off from the Force, and at best, leave them severely traumatized, or at worst, [[TakenForGranite calcified to death]]. In short, they are one of the few things that can scare [[NervesOfSteel Jedi]]. [[spoiler:The Nameless are also the subject of many horror stories InUniverse (even being tied to a prophecy pertaining to the Chosen One), and one name given to the creatures, "Shrii-ka-rai", translates to "Eaters of the Force". And while the hallucinations the Jedi experience are horrifying as is, what little we see of the Nameless's [[https://starwars.fandom.com/wiki/Nameless actual appearance]] from a non-Force user's perspective in ''[[ComicBook/StarWarsTrailOfShadows Trail of Shadows]]'' isn't any less. It's a twitchy, deathly-looking long-limbed abomination with claws, many sharp teeth, and mouth tentacles. And the bad news is that Marchion has more of the Nameless at his beck and call.]]

** The titular Xeelee are essentially SufficientlyAdvancedAliens taken to their logical conclusion. They can [[TimeTravel travel through time]], and have used it to improve their technology and power by going back as many as ''13.5 billion years''. They also use black holes as habitats and construction devices, as well as computers. Their [[MileLongShip Nightfighters]] are built of pure spacetime, and can have wingspan of miles. They built a Ring so large that it changed the movement of galaxies, that can serve as a wormhole to another universe.

** It's implied that Sauron's resurgence has awoken a number of eldritch things that were asleep. The Barrow-wights may no longer be allied with Sauron, but Tolkien's copious notes indicate that they were probably roused by the presence of the Black Riders scouting out the edges of the Shire.

* Charybdis and Abaia from ''Literature/BookOfTheNewSun'' are enormously powerful alien beings who are fated to be the EndOfTheWorld. The ignorant mass of humanity [[TheDreaded rightfully fear them]] but believe them to be the size of houses. They're not... Both of them are the size of mountain ranges and are an alien mass of tentacles that [[HotSkittyOnWailordAction dwarf]] their [[ParentalIncest daughter-wives]], the Undines - [[BizarreSexualDimorphism beautiful albino]] HumanAliens who are the size of castles. Charybdis and Abaia's biggest threat to the world before destroying it, is that they are telepathically able to reach people and tempt them into joining violent cults.

* ''Literature/{{Worm}}'':
** The eponymous "worm", aka [[spoiler: Scion]], is one of these. It is a massive wormlike SpaceWhale, composed of trillions of shards (some of which [[spoiler: can grant superpowers]]) and able to move from one alternate universe to another, even having different parts of itself in different universes at the same time. It operates on BlueAndOrangeMorality, [[spoiler: saving lives only because its [[PlanetLooters original plan]] was prevented from working by its mate's death, and becomes an OmnicidalManiac and the BigBad once Jack Slash gives it the idea]].
** It also features the [[{{Kaiju}} Endbringers]], three huge monsters that exist only to kill people. Each one has [[PersonOfMassDestruction immensely destructive superpowers]], and they have an extreme case of BizarreAlienBiology; their bodies are composed of progressively denser crystal layers, eventually reaching a literally impossible density and hardness. This makes them [[NighInvulnerable all but unkillable]], which combined with their powers and OmnicidalManiac tendencies means that humanity is pretty much doomed. On top of that, no one has any idea where they come from, and [[spoiler:it turns out they come from someone's subconscious superpower going on the fritz, taking the JackassGenie route and giving him "worthy opponents", generating enemies that could ignore the laws of physics and constantly got stronger against all logic for the sake of giving him a challenge]].
** We get a look at the shards themselves in the sequel, ''Literature/{{Ward}}''. WordOfGod originally described them as four-dimensional crystalline beings, but it turns out that doesn't do them justice: [[spoiler:they are individually intelligent and have their own personalities and desires, though certain behaviors are "hard-coded" into them by the Entity they were a part of. Each has a unique form, ranging from a vaguely human shape made entirely of spikes, a giant mass of thousands of arms, or appearing to be made of lightning. And those forms are just "cross-sections" of the being as a whole, since they are four-dimensional. This also means they move around in ways that appear impossible from a human perspective.]] The story also suggests that the Endbringers [[spoiler:are actually collections of these shards merged together in an artificial body designed to be effectively invincible to physical damage.]]

** Rh'lem, a HumanoidAbomination that looks like a man with no skin, and [[{{Cyclops}} one big yellow eye]]. [[spoiler:Rh'lem is actually [[WasOnceAMan William Howel]], [[TheProtagonist Henrietta]]'s father. He was sucked into a portal to the Ancients' world in the summer of 1822, and was warped and twisted into what eventually became Rh'lem.]]

* ''Literature/BazilBroketail'': Thingweights are creatures like huge dark clouds that live in the Void, a huge etheral plane from which a person can travel to anywhere else... assuming they avoid the Thingweights. If caught by them then people are slowly devoured. They have some kind of tentacles as well to grasp people.

* EldritchAbomination:

** Orannis the Destroyer]]. He is alternately described as a sphere of light and a column of fire, and is immortal. His [[SealedEvilInACan can]] is his own frozen body, [[HalfTheManHeUsedToBe split in half,]] buried under a hill, and encased by a seal of seven different materials, including bone. He destroyed the world several times before the Seven finally imprisoned him. Yes, that's correct: it took seven GODS to hold this thing. And his only real restriction is his power and movement; he can still communicate with and manipulate those around him. This is the most terrifying, [[MindScrew unnatural]] thing to come from the [[EldritchLocation terrifying, unnatural Kingdom.]]

* The Blight in ''Literature/AnOutcastInAnotherWorld'' warp reality by existing, and their method of passage into the world turns an area miles wide into a land that rejects life.

** Whatever it was that messed with Jake in [[BadFuture Book #41]], and "[[GiantSpaceFleaFromNowhere The One]]" (possibly the same being) in [[BolivianArmyEnding Book #54]].

%%* ''Literature/{{Animorphs}}''
%%** Crayak, and his [[TheDragon dragon]], the Drode.
%%** Whatever it was that messed with Jake in Book #41, and "The One" (possibly the same being) in Book #54.
%%** Father, in The Ellimist Chronicles.

* The titular Xeelee from the ''Literature/XeeleeSequence'' are essentially SufficientlyAdvancedAliens taken to their logical conclusion. They can [[TimeTravel travel through time]], and have used it to improve their technology and power by going back as many as ''13.5 billion years''. They also use black holes as habitats and construction devices, as well as computers. Their [[MileLongShip Nightfighters]] are built of pure spacetime, and can have wingspan of miles. They built a Ring so large that it changed the movement of galaxies, that can serve as a wormhole to another universe.

* Creator/SimonRGreen's ''Forest Kingdom'' books contain several types of Eldritch Abominations in addition to the regular [[OurDemonsAreDifferent evil demons]]. In ''Down Among The Dead Men'', the BigBad is explicitly named as an evil from beyond the dawn of time; ''Blood and Honour'' has a castle slowly turning into one (a room digests its occupants at one stage, and [[BodyHorror a person is turned into a living doorway]] to a dimension full of eldritch abominations). Amongst several others.
