Balthamos, for reasons unknown, is a brooding, rude, and constantly angry dragon. He seems to always have a seething rage of unknown origins just below the surface of his consiousness. He is only polite to Umaroth, Glaedr, and Xaphania.
Balthamos has scales that are the darkest of purple, which makes him often mistaken for a black dragon. He has bicolored eyes. One is blue, the other is green. Balthamos has an unusually large wingspan.
Balthamos's Rider is the Human Xaphania of the Wandering Tribes. She is supposed to be some distant relative of Queen Nasuada, and is the only person Balthamos actually respects. She weilds the curved blade Edoc'sil.
