pocket dimension
Contained separate space
A pocket dimension is a small, self-contained reality separate from the main universe—a bounded space with its own rules, accessible through portals or magic.
The term comes from science fiction and fantasy, where characters might store objects, hide, or trap enemies in these isolated realms: The wizard kept his library in a pocket dimension.
In gaming, pocket dimensions often serve as personal sanctuaries or dungeons.
