From the description: This adventure module is about descending into a disused fungus mine filled with Earth’s avenging agents of digestion and decay. It includes: - 13 keyed locations (including a mine, a tunneling worm's burrow, a reincarnation lab, and a secret roach city) - Unique NPCs (bugs and dirt dwellers of all sizes and personalities) - Unique treasures (shiny, medicinal, and explosive) - GM aids (faction references, NPC stat blocks, rules for exploring the dark, and item and condition cards) - And lots more gross stuff
