Once the capital of Yamasa, Kokutang is now the seasonal gathering place of the Kuboto and their reconstructed tribes. Visitors are never welcome and in fact risk becoming sustenance. While Kukotang includes a wind-washed village on the surface, much of what remains of the capital is now a complex of subterranean caves interconnected by flooded passages. Many of the hidden caverns are accessible only to those with the breath control (or magic) necessary to make the dangerous trip.
