Pocket World

A Pocket World is a vastly different area that can be found hidden behind the doors of something small like a closet or wardrobe. It is often almost indefinitely larger on the inside.

Description
This location is popular with kids as it fulfills the imaginative idea of finding hidden worlds and caves within your cabinets and closets. It will usually be a very vast and different environment inside, but it's also possible to lead into thematically closer places such as dark caves, dungeons, or even the Attic Zone. Once entered, it's unlikely to be able to return, as the entrance will easily disappear or be lost as soon as you start exploring.
