The Tibetan Interior

The expedition reaches its ultimate climax as the investigators venture deep into the unforgiving Tibetan plateau. Arriving first in the bustling, sacred streets of Lhasa and finding brief refuge at the British Legation, they must quickly prepare for a treacherous journey. Ahead lie freezing rivers, perilous mountain gorges, and hostile encounters ranging from border patrols to relentless Soviet agents commanded by the cult.

Their true destination is the ancient, snow-swept Ruins of Nen-mka, where a devastating ritual is underway. The investigators must descend into the Occult Ceremony Chamber and navigate the toxic, otherworldly Valley of the Seed. Ultimately, they will cross the threshold into the Extradimensional Great Chamber of Eibon—a surreal realm of black marble and crystallized spatial lines—to thwart a catastrophic time stasis.
