[@Retired] Actually what you've described has made things much clearer, thank you.

One more question; how would you feel about a character that has a concept of/travels through the multiverse already? The multiverse being an in-fiction concept that the character themselves is familiar with. I obviously don't plan to do anything game-breaking with this (say their ability to travel between universes has been restricted by Mojo somehow) but I wanted to see if that would put you off a character.
