Inferno

This sourcebook expands the setting with Hell, a realm inhabited by demons, angels, and Damned Souls condemned for their sins. It provides rules for entering and surviving the Void, including modified racial features, combat rules, and guidelines for playing condemned characters. The book details the nine circles of Hell, their demonic rulers, and the politics of the Fallen Host, including mysteries surrounding its leaders. It also includes new feats, spells, an expanded Infernalist spell list, and twenty-seven pre-generated characters covering demons, angels, and members of the half-demon Immunda race.
