The cracked, barren plains of the Atrocity Flats are wracked with earthquakes that constantly reshape it, opening and closing jagged fissures full of strange and primordial slime. It is suffused with invisible energies that are anathema to ordinary flora and fauna, energies that interact with the slime pits to generate the Living Atrocities and other horrors that burrow out of the flats before bursting to the surface to spread chaos and destruction. Along with the Crawling Marches, the Atrocity Flats is the most dangerous region in The Dreaming West.
