This is Odeus, he's a lizard cultist\wizard dude.

An edit! because I've added more about him.
The deity he worships is named Akh'hobb, in fact he's the only person who worships Akh'hobb, and was driven out from the cult he was originally a part of, as he was found out about his new deity, and he was also in opposition to the humanoid sacrifices they would make.
Odeus actually has a sort of relationship with Akh'hobb, what a strange couple..
