And yeah, I think that Tieflings definitely face their fair share of discrimination, there’s almost certainly a cult out there that believes the nukes were divine retribution for the existence of Tieflings. 

The only thing I would say is that if he’s gonna be capable of doing magic of any sort, including illusion spells, he’s gonna need some kind of wand or staff to channel that through. Even harmless spells become dangerous to the caster if you can’t channel it through a piece of fancy wood or maybe a crystal.
