A rogue band of drow are plaguing the artifact shipping lanes of Osirion and the Pathfinder Society has sent you to stop them. When the drow capture an entire caravan laden with Society relics, the Decemvirate orders you into the Darklands to track down the drow and their stolen cargo. You'll travel beneath Golarion, fighting through caverns of hideous creatures to reach the fabled Darklands Pyramid—will your survive the journey, or become a slave forever?
