Ah. If that's the case, then I think it'd be quite hard to justify someone who wasn't born a demon becoming a half demon. I think I'll label the backstory as "Magically accelerated evolution." He'll still breath fire and have the weird spike that allows hit to speak demon in the back of his neck, he just won't be called a demon/half-demon.  Probably called a "Warlock." I like that name.

I'll probably keep Shep as is, a bandit outside the law, and have Hero (That's my work in progress name for him. I want his name to sound at least a little like Hitoshura without being asian.) Be the standard 'good guy' with the Kingsguard. 

If, of course, that's okay with both Ala and you.

EDIT: Does that mean Shep is accepted?
