#10-20: Countdown to Round Mountain

As the Hao Jin Tapestry demiplane collapses at an increasing rate, the Pathfinder Society has decided that it must evacuate the surviving inhabitants using a powerful ritual that can return one of the demiplane's monumental sites back to the Material Plane. The only candidate large enough is Round Mountain, an immense, tunnel-ridden stone sphere pulled from the Darklands of Tian Xia centuries ago. However, in the generations since Round Mountain vanished from the Darklands, countless subterranean creatures moved into the vast cavern left behind. If the mountain returns—and it must return to save the demiplane’s refugees—it would crush all those who have moved into the cavern since.  

The Society must move quickly. The PCs are one of several teams tasked with exploring the vast cavern, cataloguing the doomed architecture, and above all coordinating the occupants' evacuation before the long ritual concludes.
