[@EchoicChamber] I've mentioned that in his bio. Really the "Release of his tail" means that if he ever snaps into reality, or if something really angers him to the point where he goes completely berserk. Easiest way in doing that is to send Thor to encounter him for the third time, in which Jörm would just go out of his way to kill the Thunder God and so forth.

Granted if you have any other ideas for what could happen, by all means let me hear it.
