The island is host to many hidden places, one being the Kuro camp. Inside a bamboo thicket is a small outcropping of obsidian. The cats believe this isn't natural and was caused by the now dormant volcano also on their territory. A almost stair-case like path spirals into the stone. There is actually lots of light inside the cavern, given that a tube of lava runs down one side and oozes over a fall at the far left. The dens are in the walls away from the lava, and 'Lava Rock' (a large and odd-shaped obsidian buldge) is in the center of the area.
