@Cinderella Man Prince brings up some valid points. Since your character is still a work in progress, I won't get after it for now. It wouldn't hurt, however, to write down some of the history that Taene's forgotten, and to give him some traits, redeeming or no, beneath the exterior.
The only technical flaw you've got is the Rationale section. The Rationale is meant to explain why the character would want to join up with the Reclaimers. Basically, why he'd abandon his allies and turn coat in the middle of battle to join us. Doing so just because he doesn't know what he's doing anymore isn't very sensible reason. Now if it's part of Taene's character that he's unintelligent, the lack of depth and rationale would make more sense, but otherwise, it is not preferable.
