Feel free to debate, but for me it seems like it would work well with a non-canon affiliation if you really need to be able to warp from this world to other worlds. The in canon multiverse in this roleplay has nothing able to flow out of this world, being a one way trip in due to the twisted up energy imbalance mumbo jumbo sciency/magicy stuff. It's an inescapable world where they have to adapt, not simply be able to go back where they came from (yes, I know it wouldn't be that simple, but still).
