From the Publisher's Website:
Beneath the desolate deserts of godless Rahadoum, the Pathfinder Society races against time to beat the traitorous Shadow Lodge to an ancient Jistkan citadel. But their rivals aren't the only obstacle in the PCs' way: the long-lost ruins teem with terrible outsiders set on manipulation and destruction, including a self-proclaimed avatar of the div god Ahriman. Beneath Forgotten Sands brings the three-part Heresy of Man series to a stunning conclusion.
Beneath Forgotten Sands is the third and final scenario in the The Heresy of Man campaign arc and is the sequel to Pathfinder Society Scenario #2-07: The Heresy of Man - Part II: Where Dark Things Sleep.
This product is a Pathfinder Society Scenario designed for 5th to 9th level characters (Tiers: 5-6 and 8-9). This scenario is designed for play in Pathfinder Society Organized Play, but can easily be adapted for use with any world.
