Enoch should have let Caleb join Lucifer. Instead, he'd wrestled Caleb to the ground and held him there until the rebellion was over. He'd saved his friend from the pit, but he couldn't save him from himself. Caleb still denounced everything Enoch held dear, and he was cast to Earth in punishment. Without the Light, Caleb wastes away, until he discovers a new life force-human blood. Worse yet, each mortal he drains is infected with his immortality, creating a race of vampires. Enoch is responsible for Caleb's mess, so Enoch's sent to Earth to clean it up. He walks the night, hunting and destroying vampires, trying to protect mortals. And he'll be stuck among mortals until Caleb repents and returns Home....which doesn't seem likely. But when Caleb's hordes come to town as Enoch is trying to hunt down a vicious serial killer, Enoch finds himself trapped in an eternal battle with his former friend as he tries to protect the people of Three Rivers from threats both human and not.
