After narrowly averting a city-wide disaster and thwarting the plans of the Council of Thieves, the heroes must consult a legendary hag - the Mother of Flies - who knows the many secrets of the thieves guild at the center of so many problems in the city of Westcrown. With the crone's unsettling advice, the heroes can infiltrate the trap-ridden headquarters of the Council of Thieves, defeat the vampiric force within it, and lift the curse of the shadowy menace from the beleaguered city. A Pathfinder adventure designed for character levels 11-12.
