From publisher blurb:
Purple Mountain III: The Feasting is a Pathfinder Roleplaying Game compatible module designed for four 3rd-level characters that uses the medium XP advancement track. Play it in any campaign setting with a mountain-based megadungeon, or as a stand-alone dungeon with a mega-dungeon feel.
Purple Mountain III: The Feasting combines the combat and daring-do of exploring dank, mysterious tunnels with the fascinating interaction of a 'sandbox' underground community! Vicious underground dwellers, forgotten shrines to a dark god, ancient curses threatening to wipe out whole races- all give your party a chance to shine, and make a little coin doing it!
