The Runestone (ルーン石, Rūnishi) is a sacred object located in an underground chamber of the Land of Runes. It is a large stone which is inscribed with all known Rune Seals (ルーン印, Rūnin) and it is an object which inspired the use of the rune seals by the denizens of Skandia. It was created by the Makino clan leader. It was later moved and concealed by the Three Kings to preserve it's knowledge and keep it hidden from outsiders.
