What about the accepted theory that the Erlking was responsible somehow for the hexenwulfen belts? I haven't been able to find that post anywhere.
When is something considered an "accepted theory"? Myself, I've always thought the idea of the Erlking being responsible for the belts was a WAG with little or nothing to support it. To be a reference item, shouldn't a theory have some kind of structure of related facts in the books supporting the idea?
I'm not trying to start up a debate here about the belts and the Erlking, I'm just saying that the only supporting clue in favor of that theory is the fact that the Erlking is a hunter, and the belts turned people into insane werewolves. Given the fact that practically every major supernatural being is a predator of some kind, that's not a very strong connection.
