Yes I am rewriting the bio as we speak, it somehow did not get copied when I posted, and afterwards I deleted the word file it was in with the thought that everything was here anyway ^^.

The ambition question is spot on, he has it, but will only try to seize power when a lot of factors are swinging his way.
In line with that is his use of the force, he values controll, but he can only display truely powerfull feats in the force when in genuine rage.

As for a master: EVERYONE: consider this an open application. Do you want somebody to push around? Do you want someone that is loyal dispite most things? Arunash is the man for you!

as for force powers, working on them as well, but I am thinking of investing him in the defensive powers mainly (tutaminis) as those are the powers he uses while not in rage, than having a few that he can use when he taps into his anger. I haven't had the time to look at the list you put up though.
