Weakened by his contact with mortals, the Archangel Raphael falls prey to his brother Lucifer, who strips him of his angelic powers. Sold in the Moorish slave markets, confused and humbled by his sudden humanity, Raphael finds his only solace in the friendship of the darkskinned Berber woman Djoura, and the spiritual guardianship of his former pupil Damiano Delstrego.
Accompanied by the rakish Gaspare and an ancient black dragon, Damiano's beloved Saara embarks on a quest to rescue Raphael. Their odyssey leads them to a shattering confrontation with the Father of Lies and a transcendent reckoning with destiny.
