The Godsrain has caused chaos throughout Golarion, but it has also caused opportunity. The rain of pieces of Gorum's Armor, the Warshards, has lead to a race of various groups to collect these artifacts, either for study or more nefarious purposes. The Pathfinder Society has collected several themselves, and learned of a way to find more. When they employed this ritual, though, it pointed to the Netherworld within the Gravelands. A piece of surpassing size and power lies within the reach of Tar Baphon, the Whispering Tyrant. Fortunately the Society has a plane-hopping airship gained in its defeat of the hag Aslynn, as well as some strange fruit empowered by the silver rain that can grant the power of mythic heroes. But will that be enough to retrieve this item of power before the Whispering Tyrant claims it?
