* ''Series/TheMagicians'':

How can this door bend space and time like a Dali painting? It may be a technological {{teleportation}} device, a TimeMachine (or both). It could also be made through magic (which usually justifies it being otherwise mundane looking), and may lead to the MagicLand, SpiritWorld or DarkWorld. Lastly, it may be some form of "naturally" occurring gateway of Eldritch origin that leads to an AnotherDimension.
