Multiverse

Inevitably, the local universe which most of us live in is actually one of countless universes floating in the vast multiverse which is said to stretch on for eternity however, it is not the only one.

The overall leader of this Multiverse however, is an Imperial whose said to have legendary powers compared to other beings in the multiverse including the dimensional monarchs who are able to rewrite the laws regarding causality in ways that are impossible for lesser beings with one (who we probably all know about) even plotting to usurp the power of the imperial to take control of the multiverse.

The Multiverse itself in arranged in a system where it's subdivided into sections to minimise the complication of addressing across such a vast space.

Clusters
The smallest of such subdivisions are the Universe Clusters which are reigned over by a dimension lord although, the running of individual universes is delegated to the universe-class beings along with the universe itself which is also, universe-class as it has intelligence and so, can manage itself.

An example of these universe clusters being the Kupo Cluster which this universe resides in among countless other universes which is managed by the Kupo Clan.
