He was an alright character. I used him most of the time cuz he was pretty strong (I'm more of a physical damage guy than magical). I didn't much like the fact that there wasn't too much to his storyline, but he's a character nevertheless so there's nothing I can do about it.
Did you read that on this site? There are quite a bit of fan-made novelizations here. It might have been something to add to his storyline.
