Ashvyn Caverns

Before the sinking of the island, these caverns and caves were used as protection against hurricanes and to store crops. But as the caves only go deeper, never going up, most of the caverns are filled with sea water. There are many creatures trapped within Ashvyn, even a mermaid or two. But something trapped within the caverns is also doing something horrible, creating earthquakes that rock the entire island. These caverns are dangerous and not to be disturbed.
