Ever since Malphus lost his partner, revenge is all that matters. But after discovering an ancient power flowing through his veins, Malphus receives an invitation he cannot ignore. The Isle of Ov, a grim citadel where the despicable and the destitute transform themselves into living weapons, welcomes him into its silent crucible… under threat of damnation. As Malphus struggles to complete his training without losing his soul, a world-ending Darkness creates for itself a new shape, evolving beyond what anyone had ever thought possible. To save the world, Malphus must let go of the past, master his powers, and fight alongside his enemies… but even then, he cannot rely on one timeline alone.
