I always thought that a good trollish martial art would be Pankraten. I am
told that this is a Greek martial art that involves a lot of wrestling and
punching with moves for wrenching joints and breaking bones. I can't say for
sure that this is a "real" martial art, but it could just be obscure like
Savate.
Owen James' rune looks suspiciously like the Hunger rune. Considering who it
is associated with, I could quite easily consider them Chaotic. :)
