Hidden away in the mountain range that cuts the Kyoushu territory in half are the cave communities of the Hidden people. Of special notice is the capital city of Sumidoru, the city hidden in the tallest mountain, the city grows out of a breathtakingly large natural cavern in the mountain, stone structures dot the floor of the cave, though these are not homes but tribal common grounds. Lining the walls of the cave are many alcoves, homes and common rooms, each interconnected with elaborate tunnels and rope systems. Green moss glows gently from many of the surfaces of the huge cave. Radiating in strength, the green moss surrounds the surface of one huge central column. The towering column rose high into the cave, ending in a point just before the apex of the cave. Many of the Kyoushu can be seen moving about, some on the elaborate walls, other on the floor. Large markets dotted the floor where huge crowds gathered to haggle for wares and services. Other than this there were collections of outfitted Hidden, mercenary organizations offering their services to the highest bidder. Many springs and a few rivulets wound there way through the cave floor providing fresh water to the tribe.
