Pocket Dimensions

A man playing God.

Pocket Dimensions are tiny, self-contained Universes that are created within the spacelessness between universes, within a Multiverse. They are a space within a space, but inaccessible spatially.

They can be very small, a witch with a never-ending purse, or a wizard school in Antarctic. They can occur naturally, like the latter, but oftentimes a wizard will create a tiny dimension to hold his spell book. Because they are not accessible spatially, a wizard with the know how can open a portal to a pocket dimension from anywhere.

Hierarchy

 * They exist within spacelessness, and spellcasters are able to produce them, and produce a portal to them from within their universe.

Trivia

 * They are temporary, unless grown to sufficient size, because the "gravity" of spacelessness compresses them.
