In the back of a series of caves found at the bottom of the hole lay a set of ancient ruins. There is a theory that these ruins were once the center of the Ancient Armes Dynasty. A vision, similar to the one experienced at Ceras Lake Ruins about the Dawn Rune, was experienced there but any connection is unknown.
It is said that these ruins suddenly became inaccessible after the conclusion of the Sun Rune War, once Eresh had disappeared.
