Type VII

A type VII or K7 civilization would travel, transcend and potentially encompass the omniverse which is the collection of every single universe, multiverse, megaverse, paraverse, 11d dimension and 1st realm (reality).

It is likely that such power would come from an individual rather than a civilization, as the civilization would have transcended and merged into a single mind that would encompass all thoughts and all timelines, thus being omnipotent, omnipresent, and omniscient within the confines of the 11 dimensions of the omniverse. Such a being is godly, but not to be confused with the Creator who is the ultimate supreme being outside of reality.
