This is a story about the Horsemen of the Apocalypse and how they rode to save the Devil.
Damned to Hell after a life of misery, Niccolo da Firenze soon discovered Lucifer's prison was not what the Church had always claimed. His new home was a breath of fresh air, Lucifer was a wise and gentle leader, and Niccolo quickly rose through the ranks and became the Horseman of Pestilence. Surrounded by new family and friends, accepted despite his faults, Niccolo would often forget his part in the coming Apocalypse.
That bliss came to an end once Cadmus, the Horseman of Death, inherits a vision of Lucifer's murder. So, with his fellow Horseman by his side, Niccolo begins his frantic journey to uncover a conspiracy involving ancient demons, corrupted humans and even a few gods.
