I don't really see anything wrong with Asuma either (surprised no one's thought of making an Akavir OC) but I am iffy on the subject of a wooden sword being able to [i]cut through anything[/i].  Even if the blade was enchanted, I doubt it would have any effect on structural integrity and the blade would still snap like pocky.  Plus I don't see what's wrong with a fifteen year old using a real sword, but that's just my two cents.  Not meaning to dog your character, just find it bizarre to use a wooden weapon in battle, essentially a toy.  But yeah, still a neat character ^.^

As for Skharn....errrr....in the words of Enthir: "Intriguing...but highly disturbing." O.o. Buuuuuut he can be Tarja's pet if you want \^o^/
