Though the angels emerged victorious, banishing Lucifer and his demon followers, a new threat emerged. To safeguard humanity, The celestial council made a momentous decision - the creation of the Purebloods. These elite warriors, sired by the Archangels Uriel, Raziel, Metatron, and Raguel, were tasked with protecting mortals from the shadows. Invisible to most humans, Purebloods lived among them, ever vigilant against the lingering darkness. Evelyn Thorne, a stoic and unwavering Pureblood leader, dedicates her life to this sacred duty.

Their forbidden union results in a son, Kai, a secret Zeron desperately tries to shield. Whispers of a demon child with Lucifer's blood ignite fear of another uprising. Torn between love, duty, and the looming threat, Evelyn and Zeron must confront their past choices and unite Purebloods and angels. Can they overcome their differences or will the sins of the past unleash a darkness that engulfs the world?
