Avernus Survival Guide
[A chapter titled 'On Traversing the First Layer'. The text details the terrain of the Avernus - a bleak, rocky landscape beneath a black sky, with rivers of blood rushing between the cracks. The most frequent guidance given to adventurers on encountering any of plane's many physical perils - to simply turn around and run. To combat the spiritual perils, the company of a cleric is of paramount importance: to soothe those swayed by the plane's evil influence, or to consecrate the corpses of those who succumb.]
