The Aspis Consortium and Vanji Prospectors’ Guild may have allied to extract valuable minerals from the tropical Kaava Lands, yet their endeavor also threatens to release a fiend sealed beneath the nearby ruins. The Pathfinder Society and its new friends have strangled the operation economically, causing most of the workers to abandon the dig. However, a dedicated corps is trying to dig out one last lucrative (and perilous) haul before evacuating the site. The PCs range deep into the jungles alongside their grippli allies to stop the Aspis—and perhaps confront the same fiend imprisoned millennia ago.
