Black Sun Rising

The investigators have breached the metallic rifts and arrived at the inverted, hollow city of Yian-Ho at the center of the Earth. Here, a desperate and terrifying landscape of black frost and bizarre alien geometry sets the stage for the ultimate confrontation. Thetnoris is on the verge of completing a cataclysmic ritual to siphon the unfathomable power of Nug and Yeb, threatening to plunge the entire world into eternal darkness.

Navigating through collapsing maze-like streets and over rivers of ink-black water, the heroes must assault the dark fire ritual center. They will face mutated cultists entrenched behind black ice barricades before gazing upon the horrific cosmic Orb itself. Success means triggering a catastrophic energy storm, turning the rescue mission into a frantic, deadly escape back to the surface before the subterranean world implodes.
