I really love what you've come up with here. 
There are three things in question, however:
1.) What doesn't "Elewani" mean? (curious is all)
2.) What about his Earth skill? I know you mentioned in the IntChk that he would be an Expert, but you didn't list it under Martial Arts. I am also curious as to how he might implement it in his own way (which I will do in a bit for my own character).
3.) When did he start practicing Tsuchi-Furo? It does not say when in the History. If he just picked it up or began to experiment with it, that'd be interesting to know as well.

Overall, very interesting character. Seems cliche (darn you A:tLA) that he's blind, but I still love the idea. I can tell we're going to have fun. ^^
