Council of Thieves

Publisher blurb:

Don't go out after dark! In the run-down Chelish capital of Westcrown, fallen from grace generations ago by the rise of the devil-worshiping House of Thrune, strange beasts of shadow prowl the streets after nightfall. At the same time, the head of the city's all-powerful crime syndicate, the notorious Council of Thieves, has grown unstable, and a new power is determined to take control—even if it means burning Westcrown to the ground.

The Council of Thieves Adventure Path is a gritty, urban adventure of organized crime, corrupt officials, and ancient curses. In their efforts to help the revolutionary Children of Westcrown, the heroes must infiltrate the halls of power, moonlight as actors in a deadly play, delve into a condemned Pathfinder Lodge and a mad wizard's labyrinth, make deals with hags, and face down the hordes of Hell itself—all while pursued relentlessly by vampires, assassins, and the infamous law-keepers known as Hellknights.
