Extradimensionality

Cobyslarni opens a portal in his third eye to an extradimensional archive.

The term extradimensional describes a metaphysical existence outside of any plane or dimension. (The term nondimensional is synonymous.) For example, a bag of holding stores objects in a tiny extradimensional space that does not exist as part of any other dimension, including the dimension on which the container itself exists.

Extradimensional interactions

Extradimensional spaces can serve many functions, and are most often created as a result of magic, particularly spells and magic items.

Extradimensional spaces are often useful for moving cumbersome or dangerous objects, as their weight does not increase with their contents and are sealed environments not prone to outside contamination when closed. Likewise, extradimensional shelters can protect creatures inside them from the elements, though some rely on circulating air from outside.

An entrance to extradimensional spaces created by certain spells, such as mage's magnificent mansion or rope trick, does not move with ships.

Reactions between extradimensional objects

Extradimensional spaces can be subject to unusual reactions when combined. For instance, placing an extradimensional container into the extradimensional space of a rope trick prevents access to the container's extradimensional space until the container is removed from the space. Another example involves direct interactions between a bag of holding and a portable hole, which can destroy or exile both objects and create a planar rift or portal to the Astral Plane.
