Synopsis: From the back cover of the DAW first edition: "Dragon magic had been the key used by Nimbulan, last and greatest of the Battlemages, to halt the devastating magic-fueled warsw that threatened to destroy the fledgling kingdom of Coronnan. Yet the personal cost of peace was extremely high for Nimbulan, who ultimately lost his own magic power in the struggle to protect Coronnan and to created the Commune of Magicians. Now Coronnan faces new and equally deadly dangers as: a Terran-based plague begins to spread through the outlying lands; the queen's own father plots to introduce forbidden technology in exchange for the previous resources needed by his own people; and the current head of the Commune of Magicians launches a campaign to bring all magical knowledge and power completely under his control. And even as King Quinnault finds his reign attacked by hidden enemies both within and outside of Coronnan, those who could aid him are themselves pursuing their own perilous quests - quests which will lead through the void and into the city of Hanassa, the one place to which no dragon will fly, the home base of Rover rebels and the Renegade Dragon."
