Universal Hierarchy

The Universal Hierarchy refers to the many layered [x]-verses.
The top layer is Our Reality, the second layer is the Fourth Wall, the third layer is The Omniversal Void, the fourth is The Multiverse, and the fifth is the xA's Universe.
The Omniversal Void splits off into The Multiverse and The Dimensionless Void.
The Multiverse splits off into an infinite amount of universes, including the xA's Universe, The Blank Plain, Polyhedral City, and The Chaos.
