Cavern of Earth

The Earth Cave is a location from Final Fantasy I. It is located south of Melmond, and the Warriors of Light must come here to find the source of the earth's rot. They defeat a Vampire, but this fails to stop the rotting. They later return with a rod, and expose a secret passage leading deeper into the cave. Here, they find and defeat Lich, the Fiend of Earth, to finally get rid of the rot.
