Location: West Coast of North America
"Kasm gets its name from the huge rift (or chasm) that now stretches nearly all the way across the former western United States. It was caused during the End War, most likely from multiple nuclear warheads. The rift seperates Kasm from the rest of the continent. The only way to get to the other side is to go around, cross a bridge (few and far between), or climb down and back up the other side."
