Call of Cthulhu - Edge of Darkness

About the adventure

Edge of Darkness A Classic Call of Cthulhu Investigation of Guilt, Legacy, and the Occult You are summoned to the deathbed of Rupert Merriweather, a frail, regretful old man who, in his final hours, seeks to unburden his conscience. His voice trembles as he reveals a secret he and his friends have carried for over four decades—a secret that now threatens to break free of its shackles and bring ruin to the world. In the 1870s, Merriweather and a circle of youthful occult dabblers conducted a ritual at a secluded farmhouse outside Arkham. Their careless attempt to contact and bind a supernatural entity went horribly wrong. They succeeded in summoning something… but not in controlling it. Terrified by what they unleashed, the group managed to trap the entity within the farmhouse using arcane means. Believing it safely imprisoned, they sealed the property, swore never to return, and tried to forget what they had done. But evil does not sleep forever. Now, the wards holding the entity grow weak. Merriweather, consumed by guilt and fear, gives you a locked box containing a journal, ritual notes, and the deed to the long-abandoned farmhouse. He begs you to finish what he and his friends could not—to confront the evil they bound and see it ended, before it escapes and exacts vengeance upon the living. Your investigation begins with this simple bequest, but the path ahead is fraught with peril. As you uncover the truth behind the ritual, the occult, and the unnatural being locked within the farmhouse, you will be forced to question what is real—and what lies just beyond the veil of human understanding. This is a story of hubris and horror, of consequences that ripple across decades. The sins of the past have come due, and now it falls to you to put things right… or suffer the same fate as those who came before.
