Billing itself as "a tome of black magic," Infernalism: the Path of Screams examines the motivations and methods of those who sell their souls for power, or devote their lives to the un-doing of Creation.

It then moves on to the things Infernalists get in return for their souls, from money and influence to supernatural powers. Matters are rounded off with some examples of demonic influence on Earthly societies, and a brief bestiary of demons and their masters for GMs to incorporate into their games,
