Layers of Existence

The "layers of existence" refers to the way the universe is build.

Universe -> Multiverse -> Omniverse

The singular omniverse contains an infinite number of multiverses which each contain a near infinite amount of universes. Kirk, existing as a paradimentional being, spawner of the old gods from the first multiverse, can travel between these layers at will and often kills multiverses when he is bored, or by accident.

While elder beings such as Kirk have created multiverses, It is unknown who created the current incarnation of the omniverse but it is believed there must be beings that exist outside in the void.

There may have been prior omniverses, though this is simply conjecture. Kirk 386 may be from this hypothetical previous, hypothetical omniverse. His book, the Abyss, may contain the answers to these questions, but translating it is near impossible with current celestial technology.
