His uncle Ronan Kane embezzled resources, plotting to seize the Dragon Lord position. Kael actually awakened the heaven-defying Ancient Devouring Black Dragon. He breaks conspiracies, devours enemies, sweeps through the Kane Clan, conquers secret realms, breaks into the Imperial Capital, and duels the Dragon Emperor!
