The great city is besieged. Mareg Dru'artha Sutnavanistra, Dragon Lord, has sent his vast armies and his dragons against the kingdom. The young Guardian Andra is now King. Only he can wield Abreotan's dragon Slaying sword. But will a magical sword and an ancient prophecy be enough to defeat the Dragon Lord?
The powerful wizard A Ahmud Ki plots to claim his own inheritance: the elusive Fifth Ki of magic - and the secrets of the Dragon Lords. Andra needs his help against Mareg - but can the wizard be trusted?
The final battle is played out between the legacies of the past, and Andra must confront not just a Dragon Lord, but the future of magic itself.
