Enter the Pallid Peak

Publisher's blurb: After the volcano Droskar's Crag erupted over 700 years ago, destroying many nearby cities in a cataclysm that would come to be known as the Rending, the dwarven empire of Tar Khadurrn fractured and eventually collapsed. Recently, a group of prospectors discovered a mountainside entrance to what they believe to be a sprawling dwarven complex, but they retreated from the dangers they found within. They have reported their discovery to the Pathfinder Society's lodge in Ulfden, and the Society is preparing to dispatch a group of agents to enter the mountain and learn what they can about the ruins within.
