"Help Me...Oh My God, Help Me!"
These are the words of the mysterious figure the city of Hollowvale calls the "Nocturn". What they do know is that he flies over the city every night, saving lives and fighting monsters. What they don't know is that in the day, he is Coleman Conner Smith, a man cursed with hideous wings which burst from his arms every time the sun goes down. Finding no other alternative, Coleman uses his condition to protect the innocent and wage war on evil.
However, his already messed-up life is turned upside down when two new faces enter town; the first being Gorgryph, a hideous, ancient beast hell-bent on committing the ultimate blasphemy, and Krystal, a beautiful young woman who is anxious to help Coleman escape his dark place. Burdened by his intense self-hatred and threatened by evil forces at every turn, Coleman must save not only hundreds of victims Gorgryph plans to destroy, but must also save his own soul. From the gates of his personal hell to the roof of a majestic cathedral, Coleman's journey will reveal to him his true purpose as an instrument of righteousness...and bring him back to the God he has forsaken.
