History Main / PortalCrossroadWorld

* 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 four other worlds and another ruin on the same world. Of these, two of the portals connect to different parts of the a single 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]].

** [[DownplayedTrope Downplayed]] with Three Portlands, 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.

* ''WesternAnimation/FinalSpace'': {{Inverted}} with the titular alternate dimension: "All timelines flow into Final Space." What these words mean is that there's only one version of Final Space which transcends all AlternateTimeline versions of the main universe, and all the flotsam and jetsam from these timelines which get transported to Final Space -- most prominently the [[AlternateSelf alternate Gary's]] [[spoiler:and alternate Earths]] whom entered the breach -- all end up in the same dimension, as shown in Seasons 2 and 3.

** The Concordant Domain of the Outlands are said to be the "hub" of the Great Wheel cosmology, and settlements evenly-spaced about from the plane's central spire contain freestanding portals to every one of the Outer Planes. Situated atop that infinitely-tall spire is the planar metropolis of Sigil, the heart of the ''TabletopGame/{{Planescape}}'' setting. Sigil covers the inside of a torus (don't ask natives what's on the "outside") with no access points to the rest of Outland, instead the city is rife with planar gateways to more or less anywhere, assuming the would-be traveler knows how to activate the portal they seek. Sigil is thus known as the "City of Doors," though another epithet for it is "the Cage," due to both the difficulty of leaving if you lack the right key to return home, as well as the difficulty in finding a ''reason'' to leave.

* ''WebOriginal/OrionsArm'' has [[https://www.orionsarm.com/eg-article/48449f48ded67 Aksijaha, the Root of the Eye]]. It's a system with literally hundreds of wormholes and anyone who travels far enough through the wormhole network will pass through it. The Eye is an [[DeusEstMachina AI god]] who oversees the system and ensures that no one learns of the Root's location or even existence.

* In 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.

* ''VideoGame/NappleTale'' applies this trope in more than one way. In plot terms, [[DreamLand Napple World]] lies between life and death; in gameplay terms Napple Town is the HubLevel that connects all of the season-themed worlds which the main character must explore.

* In ''Literature/GloryRoad'' Earth is important because it has many portals; it might even be the birthplace of himanity- other than that, it's considered a dumpy backwater.
