The only way in is by diving in the North Crevasse, and going through Giant's Lair. The wreck of the HD-9 Submarine piloted by the late Matthias Louvier is still seen here. This is the resting place of the final piece of the Dragon Flute. The only forms of life found here a couple of giant sea spiders found under a glow. If the sea spiders aren't there, a humpback anglerfish will replace them.
