Beyond

The Beyond is an undiscoverable realm (or realms) beyond all of reality and non-reality. It is beyond the outerverse, beyond the adverse, beyond the cosmos, and beyond oblivion. The Beyonders protect entry into this realm. What lies beyond is unknown and unknowable, except for concepts passed on to lower level beings.

Concepts
There is a Gate at the edge of Beyond, which can only be opened by a Key. The Gate is the entrance to a Citadel which are protected by a class of Beyonders as well as unfathomable dimensional magic that redirects all who approach.

Beyond the Citadel is the Pyramid which has multiple levels that may or may not represent realms.
