So here's a quick thought. Have you considered just making your new Au Ra a skillful gladiator, who holds the same ideals that are common to the sultansworn? Â
He could still be a fiercely dedicated protector of the weak, and he could still harbour feelings of inadequacy. Maybe surrounding the fact that he never got a chance to join the sultansworn?
There is no reason that he needed to learn his swordsmanship in Ul'dah either. I'm sure there are many skilled blade masters in Doma and other lands, who could take on an Au Ra student and train him in the same skills used at the Gladiator's guild. Maybe he picked up his moral stance from that teacher in Doma but left his apprenticeship, feeling he was not worthy?
