Diogenes

With a paunch, a prematurely receding hairline, and a sarcastic tone that is lost on most people, this blue-robed wizard possesses an everyman’s charm.
Diogenes is a student at Gabal's School of War, and met the party at the gate of the school during the Ragesian siege of Gate Pass. He was smoking. He suggested that Gabal may not view Jack too favorably. 
Diogenes led the party to Shealis. He was not quiet about his dislike for Shealis. After the party was roundly defeated by Shealis, Diogenes stepped in to give some guidance, and also offered two health potions.
Diogenes is funny and chill. We all love him.
