Clichely
Something is wrong.
A multiverse's creators have been banned from their own creations, rendered unable to even see their multiverse, much less control it. It was one of the creations-which, they don't know. But if the culprit escapes, or even manages to cross over into a different multiverse? Every creator could lose everything in this world.
You and several others have been chosen to find the culprit, as well as any accomplices who may know the secrets of how to permanently ban a creator. You have few limits on what you can do; surely, at least some of the others must know who did it. Lie, cheat, bribe, interrogate-do whatever you can to find them. There is only one guideline:
Don't kill them; don't destroy the multiverse. That wouldn't be fun, now, would it?
Find the culprit. Pass judgment. Protect yourself at all costs.
