Saw the edits to the information, and I really like the extra characters and depth you've added. I do have a minor nitpick though: in the original Wormverse, Earths were named for letters of the Hebrew alphabet: Aleph, Bet, Gimel, etc. If you're looking for the last letter of the Hebrew alphabet, Wikipedia says it's Tav, not Omeg. Of course, it's your world and you're free to name it however you like, just putting that out there.

Also, since it's an AU, do Endbringers still exist? Scion? The Triumvirate? PHO? Should we assume that nothing from Earth Bet carries over except what you explicitly state?
