When a decadent noble mansion in the crumbling former capital city of Westcrown erupts into an enormous pillar of fire, the heroes of The Council of Thieves Adventure Path must explore the exposed chambers of the ruined estate to piece together the nefarious plot that has released a powerful devil into the treacherous foundation dungeons. Can they weaken the diabolical fiend enough to have a chance to defeat it, or will the heroes finally fall to the insidious plots of the Council of Thieves? A Pathfinder adventure designed for character levels 9-10. The Council of Thieves Adventure Path is the first to take full advantage of the new Pathfinder Roleplaying Game rules, and works with both the Pathfinder RPG and the standard 3.5 fantasy RPG rules set.
