Type VI

A Type VI or K6 civilization exists in the megaverse and is capable of creating and maintaining the fundamental laws of universes and multiverses. They exist in an infinite amount of simultaneously existing multiverses that represent an infinite amount of time-based outcomes and inter-universal laws for every one. They can also be regarded as paraversal as they exist outside or in parallel to the space-time continuum.
