The underworld of the city of Baygrave hides more than common criminals, it hides vampires and werewolves. To make things worse, a war is brewing between the two genetically modified factions that prowl in the shadows, Count Crimson controls his New Vampiric Court to recover the power he once had, while the Lycans follow Dominic Arcon in the path to destroy their mortal enemies.
The city's last hope has come in the form of three hunters who have been called in as a part of the Crimson Protocol and will stop at nothing to end the battle between the two factions.
