The Omniverse

The Omniverse is a verse that holds megaverses which holds multiverses which holds universes and so on. Basically, It's everything that exists. Time, space, reality, galaxies, stars, planets, etc. The Omniverse was created after a being sacrificed himself to create existence. It's unknown what's outside the Omniverse or if it even has an outside. It is, however, thought to have an end, but outside is just a dark void of nothingness.
