The Neo-Caverns are somewhere near the edge of the world, and truly huge. They're called the Neo-Caverns because some of the caves have things from the past - cavemen, dinosaurs, even things from the Precambrian era. The upper levels are fine and normal, and often used for shelter. However, the lower levels are inhabited by haunts from the past - though, unlike the way things were in the original Caverns of Time, the things haunting these caves are real and can hurt and even kill you. Many loners who have just become adults go here for a test of strength, and sometimes come out with a trophy from their hunts, if they come out at all.
