For the spell, see Demiplane (spell).

A demiplane is a small plane with its own unique properties.[1] They may be created by powerful forces,[2] but wizards and other spellcasters can create demiplanes using spells such as demiplane[3] and Mordenkainen's magnificent mansion.[4] Demiplanes are known to form naturally as well, as small sections of reality separated from the larger multiverse; a demiplane may even be a "baby universe" of its own.[2]

Demiplanes can generally be entered through a specific point where it touches on another plane,[2] such as the door generated by the demiplane spell.[3] Plane shift can also transport individuals to a demiplane, but it is difficult to find the proper frequency for the required tuning fork; the gate spell is a more reliable option.[2]

Portals to many demiplanes can be found within the Ethereal Plane,[5] but demiplanes can be connected to other planes as well.[1]

Other planes have been mistaken for demiplanes. The Shadowfell was once known as the Demiplane of Shadow, before it was revealed to be a plane unto itself.[6][7]
