Lost World in Blue

In May 1935, the investigators plunge into the subterranean realm of K'n-yan, a world bathed in an eerie electric blue light. What was once a glorious civilization of gold and basalt has devolved into a decadent nightmare. The party must navigate arid hills, monstrous plantations, and the abandoned golden ruins of ancient cities to track down Esmeralda Ashe's cult.

Along the way, they will cross paths with the nomadic T'lhya tribe, explore treacherous catacombs, and infiltrate the City of Gold, V'thruu. Dark temples dedicated to forgotten gods like Tulu and Tsathoggua loom over the landscape, harboring secrets that humanity was never meant to discover.

The journey reaches its terrifying climax as the explorers seek the path to Yian-Ho, leading them to the Chasm of Zyth-eb—a colossal descent into absolute darkness where the blue light fades into a nightmarish, suffocating abyss.
