Multiverse/Spenpiano

The Multiverse is an infinite series of parallel universes and dimensions existing separately, yet alongside one another on a continuous stream.

List of Universes

 * Reality-6217 - the prime universe, wherein nearly all known characters reside and almost all known events have occurred.
