Delve into the chilling world of Call of Cthulhu, where creeping madness and cosmic horror reign supreme, inspired by Lovecraft's iconic universe. As private investigator Pierce in 1924, you're drawn into the mysterious death of the Hawkins family on Darkwater Island, and soon find yourself ensnared in a terrifying web of conspiracies, cultists, and otherworldly entities. You must steel yourself to investigate those sanity-blasting clues central to any Cthulhu Mythos game.

Navigate a reality where nothing is quite as it seems and your sanity hangs by a thread. As you explore the island, you'll encounter strange creatures, delve into weird science, and confront the sinister cults that dominate the Cthulhu Mythos. All the while, you will struggle to maintain your grip on reality, which makes playing That Cthulhu RPG an exercise in psychological endurance.

Your mind will suffer as you question everything around you, and lurking figures hide in the shadows, awaiting the Great Dreamer's awakening. The resources of the Keeper of Arcane Lore will become vital if you plan to survive, remember, knowledge is your greatest weapon.
