Synopsis
In a realm where power and desire intertwine, Azrael Shadowraven de Nightfall reigns as the crown prince of shadows, feared by mortals and revered by demons. Every wish comes at a cost—soul or body—an offer he makes to those who summon him. Yet, when sent on a secret mission to the mortal realm, everything changes. Disguised among mortals, he draws the attention of vampires, ignites jealousy and admiration, and intrigues with angels. Meanwhile, his own kind plots against him, eager to seize his power. Unbeknownst to him, a terrifying force lies dormant within, capable of turning him into the ruler of all realms—or a harbinger of destruction.
