A Cold Fire Within is a campaign for Pulp Cthulhu.Set in 1935, a missing persons case leads to the discovery of a foul plot that could change time itself and bring disaster to the world. A cult intent on unleashing the power of the Great Old Ones leaves a trail through the Catskill Mountains and into the very heart of the planet!Within the subterranean world of K'n-yan, the heroes will encounter forgotten secrets, strange lore, and bewildering inhabitants. Curious cities of gold, ruined temples, and dark forests are just some of the terrors that lurk below the ground. Yet, before the heroes descend into nightmare, they must contend with remnants of ancient worlds, unruly mountain people, and psychic devilry. Along the way, the heroes may find that going back to the end of an ancient city is the only answer! Perhaps in Lomar's doom shall they unlock the secrets of both past and present.
