Long before the great disaster, before human beings began to evolve, the dread Elder Things ruled Terra A.D.

At the Mutants of Madness is an MCC RPG adventure designed for four to six 7th-level PCs. It concerns the retrieval of an artifact of mighty power that will ensure the safety of the seekers’ village.

Inside you’ll find:
Travel procedures and random encounters for the Devillands, from the Cronenbergian Croachlings to the water-stealing Silane Serpent.

The Great Radiation Barrier, an ever-fluctuating no-mans-land of strange occurrences.

Over a dozen keyed locations with merchants, factions, and unique encounters.
