Le flambeau des profondeurs (The Torch of the Deep) is a Pulp Cthulhu campaign set in 1935. As the story unfolds, a series of disappearances leads to the discovery of a plot that could alter time and bring about the end of the world. The heroes set out in pursuit of a cult determined to unleash the power of the Great Old Ones. Their trail will lead them through the Catskill Mountains and to the center of the earth!

In the underground world of K'n-yan, they will encounter forgotten secrets, a strange culture, and confusing inhabitants. Curious cities of gold, ruined temples, and dark forests are just a glimpse of the terrors that lurk beneath the earth. But before venturing into the heart of this nightmare, the heroes will have to deal with remnants of ancient worlds, unruly mountain dwellers, and psychic machinations. Along the way, they may realize that their only solution is to witness the fall of an ancient city! Perhaps the collapse of Lomar will allow them to unlock the secrets of the past and present.

A six-part campaign for Pulp Cthulhu, The Torch of the Deep introduces new rules and skills for psychic powers, new spells, descriptions of the peoples and lands of K'n-yan, and a new hero organization: the Open Mind Group. This book also includes six pre-generated heroes.

Terrifying monsters, mystical plots, and psychic powers... an epic, action-packed challenge awaits your heroes!
