World of Darkness — Mark Simmons

As in life, all things have a beginning, a first if you will. This book is about the very first demon created by Satan, the demon king, and how his coming into our world brings forth darkness covering the entire world.

Only DEMON, a new group of enhanced humans with remarkable powers, along with Drakos Demarion, can send the demon king back to the depths of hell and restore light back into the world.
