Legend of the 7 Stars
This pale, lanky pretty boy is sinister, cunning, and flamboyant. His job is to be the messenger of destruction for the Demon King, along with paving the way for his return; but no one said being the right hand man of the Demon King would be easy. If his smack talk and sword skill isn’t enough to finish his foes, he just reveals his true form, a dragon, to finish off those who would oppose him.
Update: Through the efforts of the heroes in the Reflecting room of the Water Temple, Harbinger was forced out of his dragon body, which in fact turned out to be Azure, the Old King of Dragons. The Shadow Demon that is Harbinger escaped in the darkness of the room.
