Somehow make it that he was actually born a wood elf but was raised as a wild elf, such as the mists messing with his mind thinking that he's a wild elf, somehow, I don't know.
Same thing with his occupation, turns out he was part of a tribe but did such terrible things to other rivaling groups that he's sort of went delirious OR the mists have screwed with his memories, if that's even a thing.
