A cavern that was uncovered during the earthquake. A landslide revealed the gaping hole in the side of one of Tannidale's cliffs. The space inside is vast and dark. There's often water on the floor, and if one listens carefully, running water and the distant ocean can be heard. In fact, a great deal of the cavern itself is underwater and accessible to sea life. This cavern leads from Tannidale to the mysterious New Land, to Tethys.
