Daris

Possibly one of the gods from the Belt of the Celeset. It's not exactly stated if he is or isn't.

He is described to have scales on his back and wings and has command over drakes.

During Carvahal's rebellion after being removed from the Belt, Daris dueled Eric the Draconat and loses allowing he rebels to reach Tiam.

Tiam later kills Daris. Possibly to create confusion during battle or punishment for his failure. This action causes his drake army to side with the rebels.
