The Dying Sun tells the story of an empire at the end of a dynasty, a world on the verge of a new age. Priestesses of the Old Gods have escaped their enchanted prison and seek royal aid in releasing their masters. The High Priest of the Akhenic Temple, faithful to the One God, denies the existence of other gods and demands a holy inquisition to destroy the Pantheon Cult; while a young Shah seeks to hold his empire together as rebellion threatens to crumble it.
