Ghosts of Earth — Kevin Kauffmann

Thinking of nothing but revenge against Azazel and Beleth, the demons responsible for the upheaval of order in Hell, Niccolo and Cadmus pursued them onto Earth only to have the portal shift and close behind them. The Horsemen found themselves standing on the plains of Napoli, their enemies nowhere to be found. However, once some allies from Hell rise to the surface, Niccolo and Cadmus quickly discover there is something more important than mere revenge. As long as Azazel and Beleth escape justice, there would be no way to know the designs of their tyrannical god or the danger they would face in the coming Apocalypse. So, even as Niccolo is plagued with memories of Lucifer's past and Cadmus is drowning in visions of the future, the Horsemen realize they have no other choice. They would avenge Hell or die trying.
