The is the first in a series that will detail the geography of Hell at scales of 1-2 miles. It describes the innermost part of Hell, including Circle 7, the Desert of Fire, Circle 8, the Pits of Torment, and Circle 9, frozen Cocytus, along with Lucifer. The escape path back to the Material Plane is briefly described.
Information is provided about important denizens of each Circle, the sins and torments, weather, and specific rules pertaining to the physical challenges faced by mortals. Each map is numbered with interesting locations, such as camps of the Infernal Legions, monuments, Libraries, mines, etc. Each location is only briefly described, but could be developed by a Games Master into a more extensive adventuring area.
Gazetteer shares common campaign background material with the forthcoming Inferno: Journey though Malebolge, and describes the same geography, at a finer scale.
