This crevasse is the southern part of the Zahhab Region Depths, the North Crevasse being it's counterpart. It contains the Southern Cavern (which is filled with Vampire Squids), and the Secret Passage that connects it to the Northern Crevasse. Inactive chimneys are found on the bottom in a large group known as Chimney Forest. In the eastern section, there are a twin pair of caves containing Giant Isopods, including the Grave Keeper. They are unfortunately in the territory of a highly aggressive Bluntnose Sixgill Shark, who guards the entrances.
