A vast underground waterfall that inhabits one of the larger side caves near Sumidoru. The great sight is fed by an underground river. Many life-forms live in this cave, and many of which are harvested by the Kyoushu as resources. Many fish live in the large lake that the waterfall empties into, some are predatory and have been reported to attack the passing swimmer. These fish live in the deeper waters near the abysses that allow the water to escape the cave and continue to flow downstream. There is no beach in this lake the water sits just below the entrances to the cave, black boats covered in glow-moss make their way silently across the water. The water itself is mostly placid, the waterfall being broken by outcroppings of rock that allow it to flow smoothly into the lake.
