The Children of Fear is a sweeping, mythos-infused campaign for Call of Cthulhu set in the 1920s across Central and South Asia. Investigators must follow the trail of a cryptic telegram, unraveling ancient secrets and confronting sinister forces from Peking to Tibet. This modular campaign lets Keepers tailor the threat level to their group's taste—whether that’s deep occultism or cosmic terror. With robust worldbuilding, immersive handouts, and flexible narrative paths, this is one of the most ambitious and rewarding campaigns in the Chaosium line.
