Lord Prestimion (Prestimion Trilogy)

New to the power and title of Coronal, Lord Prestimion finds his world shattered, in the grip of chaos and panic. As a final "gift", the rebels led by Dantirya Sambail have left the world with a fastspreading plague of madness, caused by their sorcerous treason. Now Prestimion must work to rebuild his broken world, to track down Sambail before the slow-creeping despair that infects humanity can destroy him and the world he rules.
