Many years after the war has been lost, and all the dragons slain, a lone knight travels the lands of Agonos seeking to raise an army against the demon lord Abaddon. But the kings of men are fearful, happier to suffer under Abaddon's rule than risk rising up against him, and so far, the knight's quest has proved fruitless. There is hope, however, when a healer's vision reveals that one dragon still lives. Together with an eager young squire and a reformed assassin of Abaddon, the knight sets off in search of the fabled creature.
