Forbidden secrets and dark rituals alter the face of reality in Lost Rites, the fourth Asylum Pack in the Revelations Cycle for Call of Cthulhu: The Card Game. Scientists, cultists, monsters, and relic hunters scour libraries and haunted woods for powerful Tomes and the arcane knowledge they contain. Will the magical forces they unleash hasten the end of days? Or will heroic government agents and Miskatonic University faculty be able to force the Ancient Ones back toward their eternal slumber in distant realms?
