Sandy Petersen’s Cthulhu Mythos for 5E: Yig Snake Granddaddy Act 2

Captured by the serpent folk, the heroes find an unlikely ally – a mummified-yet-living being from the distant past. Cut off from the outside world, and stranded in the wilderness of Yilan, the heroes must rely on wit & grit to survive, building themselves a stable base out here in nowhere.

But they must also bring the fight to the serpent folk, who relentlessly seek to destroy them, raiding with dinosaurs and worse.
