Can I get Abd al-Aziz, an NPC in a 3.x campaign I'm running. He's a Draconic Sorcerer from the campaign world's NotArabia and also secretly one of the leaders of the world's Illuminati-esque Asmodeus Cult. Although his identity as a Diabolist is a secret, he is publicly known as a smug magnificent bastard. "Problem, Paladin?"
As far as appearance goes, you are now imagining Jafar from Disney's Alladin. Only actually Arab, and thus fairly dark skinned. His eyes are slit-pupil dragon eyes, owing to his Draconic ancestry, and for similar reasons his fingernails are black, and elongated and appear vaguely like claws.
