The MV is split in to many regions that each have a god that that rein over them and ensure there safety. These Gods are called Multi-Verse Regional Gods, and they are gods that have gotton there universe to Elder stages and have chosen to rank up.
A Tree of Life gives birth to the energies that form universes. The energies made from A Tree of Life want to be close to The Tree of Life that birthed them causing the universes to bunch together and orbit The Tree of Life that birthed them.This is what creates a Multiverse.

Every Multiverse has a Supreme god that lords over it. They are sometimes refered to as the Multi-Verses caretaker or a Multi-Verse God. They are the next step after MVRG.
When a Universe dies in the Multi-Verse the energy goes into the surrounding universes and makes the surrounding universes unstable.
The Tree of Life after 1 full Multi-Verse cycle will bear 2 Multi-Verse Seeds and then begins to wither. 1 MV seed is usually sacrificed to the withering tree to allow it to live for 1 More MV cycle and the other one is given to a senior MVRG to start a new MV.
