Prince Harmon, who goes by the undercover alias of "Nathan", is the son of King Ganymede. He is very polite and regal, with long lavender hair and very expensive lavender clothing. He possesses the ability to speak to dragons, often speaking with Kyan and Ivor, the royal palace dragons. Following an attack on him by a rogue assassin, he has become withdrawn, soft-spoken, and odd. Rumors circulated that he was replaced by a Mimic. He has now run away from home, seeking out an ancient legend.
