In the medieval kingdom of Gwynedd, strife has long existed between the human population and the Deryni, a powerful race of magic-users. For more than a decade, a fragile peace has held under the rule of King Cinhil. The former monk reluctantly ascended the throne with the help of Camber of Culdi, Gwynedd's most revered Deryni lord, who in turn sacrificed his identity and physical form for the good of all people, earning sainthood in the process. But now Cinhil is dying, and a dark cloud is descending upon the land.

The evil king is dead, and thanks to the efforts of revered Deryni magic-user Camber of Culdi, a human liege occupies the throne of Gwynedd for the first time in nearly a century. The yoke of tyranny has finally been lifted from the shoulders of an oppressed people who suffered for decades under the cruelty of the ruling magical race. But Camber's job remains unfinished. The dangerous remnants of a conquered enemy still mass at the borders.
