Salt flats are bleak plains encrusted with saline deposits and bone-dry sand. The rare water sources in these areas are brackish.
Effect: Violence in salt flats invariably results in painful injuries. Fine salt crystals suspended in the constant breeze permeate whatever covering is placed over wounds, causing unending agony. Clean water to wash away the salt or aid in recovery is nonexistent. Dunes of the finest particulates, called salt piles, collect throughout the salt flats.
Usage: The denuding of Athas’s plant life and the gradual evaporation of its seas has resulted in vast regions of salt flats. These areas challenge travelers even when no opponents or hazards exist.
