Slow Mutants

Slow Mutants are met in the dark under the mountains beyond the desert. They are twisted, faintly glowing creatures, remnants of the old world's poisons: Mid-World counts them among the leavings of the Great Cataclysm, the ancient war of the Old Ones that soured land and blood alike. Most shun the light and gather in deep places, railway tunnels, ruins, and wastes, and travelers speak of them with dread. Some bands are little more than beasts, while others keep speech and a rough order of their own. In a world that has moved on, they are one of the plainest signs of how far it fell.
