That's an understandable concern, but I wouldn't worry too much. Just counterpart logic, I've dealt with it before. Meanwhile I have a similar situation, but in reverse, since while the "champions" are the Rock Imperium, gotta wonder what form they might take in other universes. I did consider the idea the Goddess of the Rock Imperium(though she's not a literal deity, that's just creator worship type antics) was sucked into another universe, and has been roaming as able, either of her own accord, or to try and find a way back home. Might toy with the idea more.
