@Dinh AaronMK: Frankly I assumed it was irrelevant. Incidentally, the multiverse(I assumed this was obvious) is literally the space between dimensions. I didn't even think it was worth explaining why it can function because, again, it's not immediately irrelevant, but I'd assume people from different universes still have a link to their universe, or simply inherently operate under the rules of their own universe. As would be, you know, logical, simple, and consistent.

I am absolutely not depriving people of their characters' abilities just because they decided not to place them in a faction at the start. It's grossly unfair and quite the opposite of "balance". Frankly there are plenty of plot hooks I can devise for something vast like this without doing something that eliminates the abilities of unaffiliated characters.

As for the abilities you mentioned, I would never accept someone who can read minds infinitely or effortlessly generate black holes, so it's really rather irrelevant.

@SillyGoy: Try adjusting the personality and I'll consider it.
