Shatter Clusterverse

The Shattered Clusterverse is a group of universes that share the 4 realms rule (Material, Cognitive, Spiritual, and Magic). All worlds have realms. It is birthed after the Shattering - an event in which the Shattered One died and broke into pieces that formed the many universes that follow the same law through and through.

There are those who can travel between universes within the Shattered Clusterverse - aka the Worldhoppers. They're rather mysterious people who are aware of the existence of other worlds outside their own.
