Curiously enough, Draconis seemed to be a brown dragon even though Abazigal was a blue. Like Abazigal, Draconis was a dragon capable of taking humanoid form. In fact, his alternative form was more fully human. He was a powerful mage and unarmed fighter and, as a dragon, used the troublesome technique of turning invisible in combat.
He was killed by adventurers, who took his severed head in order to pass into Abazigal's lair.
