CRAU characters cannot have been written as AUs in the game they are being taken from; they must have been brought to that game from their original universe.

I'm considering apping in a character who has memories of two previous multiverse games, and that's the only 'au' to him. I'd thought to take him straight from the second game to here, but I don't mind him having been sent back briefly before coming here instead.

Question itself is, is that generally permissible? Or is the type of AU you meant more "this character but genderbent/can spit fire/fell out a window and lost a leg as a child" AU and thus I can relax? :)

Thank you for any clarification!
