History Main / PortalCrossroadWorld

* The Nexus in ''VideoGame/HeroesOfTheStorm'' is implied to be one, connecting through the universes of various [[Creator/BlizzardEntertainment Blizzard]] games and franchises like ''VideoGame/StarCraft'', ''VideoGame/{{Warcraft}}'', ''VideoGame/{{Diablo}}'', ''VideoGame/{{Overwatch}}'', and even to the classic ones like the ''VideoGame/TheLostVikings''.

* The ''Anime/{{Pokemon}}'' short ''[[Recap/PokemonPK26PikachuWhatsThisKey Pikachu, What's this Key?]]'', Klefki is a DimensionalTraveller who takes Pikachu and friends along on one of its adventures. Klefki's own realm, whose key it keeps on its person at all times, is an area of parkland containing countless keyholes to other dimensions and a massive pile of keys to open them. The local plants resemble keys of varying designs to keep with the visual motif.

* ''WesternAnimation/StarWarsRebels'' introduces the [[PlaceBeyondTime World Between Worlds]] near the end of the show, which is basically this. Since it allows not only fast travel via fold space, but also TimeTravel, it is very dangerous to use, especially if put in the wrong hands. This is why only select individuals like [[BalanceBetweenGoodAndEvil Ezra]], [[IncorruptiblePurePureness Ahsoka]], [[GaiasVengeance lothwolves]], and [[{{Familiar}} Mo]][[BalefulPolymorph rai]] can access it, while [[BigBad Palpatine]], even while using Sith alchemy, can only stick his hand in. From what is currently known, there are portals on Lothal, Malachor, and Coruscant. The "wood between the worlds" from ''Literature/TheChroniclesOfNarnia'' are specifically stated to be an influence.

* ''Wiki/SCPFoundation'':

** Wiki/TheWanderersLibrary connects to countless interdimensional pathways called Ways that in turn connect to countless worlds. This along with its nature as a multiversal GreatBigLibraryOfEverything makes it the perfect base of operations for the Serpent's Hand. It also has its own wiki for content unrelated to the SCP Foundation's setting.

* ''TabletopGame/{{Rifts}} has Phase World. A mega city on a planet with portals (rifts) to a lot of planets and dimensions. These rifts are controlled and stable on the upper floors of the city, but will open and close randomly on the lower levels. On earth the resurfaced continent of Atlantis is a smaller example and the high amount of magic on earth makes it popular for those that can control rifts.

%%Belongs in ExtradimensionalShortcut* ComicBook/{{Nightcrawler}} teleports by travelling through a parallel dimension. The black smoke he leaves behind while teleporting is that dimension's atmosphere.

* [[FanFic/TheHeartTrilogy The]] ''[[FanFic/TheHeartTrilogy Heart]]'' [[FanFic/TheHeartTrilogy Trilogy]]: The Path of Dreams which [[spoiler:Irmo]] rules over is said to connect Middle-Earth ([[AlternateUniverse more than one version]] as it turns out) and [[TheMultiverse all alternate realities]] to Valinor via dreams. Kathryn at one point visits an [[AlternateUniverseFic Alternate Universe]] by touching the Path's gate per Irmo's command, and [[spoiler:Fankil]] believes the Path can be used to [[spoiler:find the Door of Night]].

* ''WesternAnimation/TransformersCyberverse'' introduces Unspace, a dimension that lies between Spacebridges across the {{Multiverse}}. Escaping requires a tremendous amount of energy and anything that stays there too long spontaneously disintegrates.

* The Gateway of the Ancients in ''VideoGame/AmidEvil'' is an overgrown ruin that serves as the game's HubLevel. It has six portals connecting to five worlds, which two of the portals connecting to the different parts of the same world. [[spoiler:Once the evil force that corrupted those worlds finds the gateway, it forcibly opens a seventh portal to the Void in the Gateway's basement]].

Where the Portal Crossroad World is populated and has widespread portal travel, expect the [[CultureChopSuey culture to be a strange mishmash of elements from other worlds.]]

* ''Literature/TheChroniclesOfNarnia'': ''Literature/TheMagiciansNephew'' (pub. 1955) has a universe/dimension referred to only as "The Wood Between the Worlds". It's a forest that stretches as far as the eye can see, dotted with [[PortalPool pools of ankle-deep water]]. With the proper magic (such as the rings created by Digory's uncle) these pools become portals to other universes, like our Earth or the land of Narnia. On the one hand the Wood is described as bright, peaceful and serene, but it is also completely silent and devoid of life apart from the trees and the grass. It seems to come with a dangerous, if not sinister side in that it gradually induces drowsiness in anyone inside it, and eventually to sleep - forever. All the pools also look exactly the same, meaning one can easily become hopelessly lost and never be able to find one's home pool again.
* In ''Literature/JonathanStrangeAndMrNorrell'' (pub. 2004) The King's Roads, created by John Uskglass, serve as a way to travel from place to place through mirrors. The Roads are described by magician Jonathan Strange as “...great stone halls that lead off in every direction," and with “canals of still water in stone embankments.“...staircases that rose up so high I could not see the top of them, and others that descended into utter blackness."
* The Neitherlands in ''Literature/TheMagicians'', specifically ''The Magician's Land'' (Book III, pub. 2014) The Neitherlands are an intentional variation on "The Wood Between the Worlds" of the ''[[Literature/TheChroniclesOfNarnia Narnia]]'' series.

** ''VideoGame/{{Riven}}'' has the 233rd Age, which contains linking books to all of Riven's islands, and is the only way to access Prison Island.

* Near the end of ''VideoGame/BioshockInfinite'' you will enter one of these and travel around to different {{Alternate Universe}}s.

* In the MagicalGirl CrossOver ''FanFic/ShatteredSkiesTheMorningLights'', the Lighthouse is a crystalline structure in [[VoidBetweenTheWorlds interdimensional space]] that works like this. Refugees [[Franchise/SailorMoon from]] [[Manga/CardcaptorSakura five]] [[Franchise/PrettyCure different]] [[Franchise/LyricalNanoha parallel]] [[Franchise/MadokaMagica universes]] are brought there to escape the [[ApocalypseHow destruction of their homes]].

* Sakaar from ''Film/ThorRagnarok'' is a planet surrounded by thousands of portals from across the universe, many of which appear and disappear at random. [[BlindJump Blind FTL jumps]] and other errors during teleportation can lead to you being dumped there. You can use the portals to leave, but that's easier said than done when the planet's ruled by an [[GodEmperor immortal]], [[{{Cloudcuckoolander}} questionably sane]] tyrant who ''really'' doesn't want anybody to do so.

* [[DownplayedTrope Downplayed]] with Three Portlands from the ''Wiki/SCPFoundation'', which only connects three locations within the same universe (Portland, Oregon; Portland, Maine and the Isle of Portland in the UK). It is more notable for being an anomalous city-state that operates within TheMasquerade and being neutral ground for various anomalous organizations. The Foundation and the GOC both have a presence in Three Portlands, but mostly let them go about their business as long as they keep it under wraps.

''TabletopGame/WarhammerAgeOfSigmar'' has an extra-dimensional space once known as the Allpoints, outside the Eight Mortal Realms, but connected to all of them through the [[PortalNetwork Realmgates]]. Since it was conquered and corrupted by Chaos, it is now known as the Eightpoints, and at its center is [[EvilTowerOfOminousness The Varanspire]], home base for Archaon the Everchosen, [[NamesToRunAwayFromReallyFast Exalted Grand Marshal of the Apocalypse]].
