A rogue band of drow plague the shipping lanes of Osirion and the Pathfinder Society sends you to stop them. When the drow capture a caravan laden with Society relics, you delve into the Darklands to track down the stolen cargo. Travel beneath Golarion, fight through caverns of hideous creatures, and reach the fabled Darklands Pyramid. (Tiers 7–11 by Sean K Reynolds)
