Draco in Leather Pants: While he's a very cool character, it's still important to remember that Auda is never a good person.
Evil Is Cool: Auda Ibn Jad, though a despicable and evil man, is actually on the side of the protagonists and more than once risks his life to save Khardan's neck.
Ho Yay: Mathew is (legally) Khardan's wife, and admits to being in love with him even if there's an Asexual element involved. Auda hits on Mathew throughout, even after discovering "Blossom" isn't a girl, and is very affectionate with his "brother" Khardan as well, in between propositioning Zohra. Mathew was involved with another boy who was killed by Auda's slave traders and apparently homosexuality is a total non-issue in his homeland based on his confusion about why this would upset anyone.
