As the war with the dragons intensifies, all eyes are turning to Titan Valley for help. A dragon sanctuary unlike any of the others, this one is home to enslaved dragons ruled by the powerful Giant Queen, one of the five monarchs of the magical world. In addition, it houses the arena for the Titan Games, a series of gladiator-style battles presided over by none other than Humbuggle, the demon who stole Seth's memories! Seth wants to regain his memories....

As the evil Celebrant conquers more and more dragon sanctuaries, Kendra must raise an army of friends and allies on her own to fight him because her brother Seth and Bracken are missing.
