The Sealed World

A mysterious entity that consumes worlds across the multiple universes has destroyed many variations of a planet that is 3rd from a sunstar--sometimes called "Earth" in some variations of the multiverse.   The Pantheon of Gods across the universes have banded together to save whom they can from the destroyed worlds and sealed off an entire universe, focusing on just this one world, that the entity should never be able to get to.   And thousands of strangers from different variations of this planet now all have to learn to live together on one world.

To create and protect this world, the Pantheon of Gods have selected individuals to anchor, protect and maintain it.   Across the world itself are various areas meant to make the people saved from their destroyed homeworlds feel more comfortable, even if they now have to share with various strangers.
