Multiverse

The Multiverse is the realm of the DC Universe and its Fanon. It consists of multiple versions of the same universe existing in the same physical space, but separated from each other by their vibrational resonances.

The Multiverse consists of concentric spheres, contained and separated from each other and the by walls. Its core sphere is the Orrery of Worlds, contained by the Speed Force wall. Next is the Sphere of Gods, separated by Limbo from the Monitor Sphere, which is finally contained by the Source Wall. Outside of it is the The Overvoid or The Source.
