From publisher blurb: Terrible rumors of some Witch Queen Mauug and her army of Monsters stir across the land! Meanwhile while the party was back in town resupplying and healing up, another adventure party has laid claim to the Black Stairs Dungeon! Worst of all the party according to the "claim" left on the outside of the dungeon has around 16 members in the party! Should the party turn tail and run or go in and reclaim "their" dungeon!
