The monastery is said to have an underground library filled with many great literary works, such has historical writings and scriptures including works in foreign languages. The literary works are strewn in piles of disarray on the floors, and ancient scrolls and lithographs are piled among the printed works. Priests are restricted in going to the third underground floor. In the deepest area of the vault the floor covers a tunnel entrance, and a magickal rune is inscribed on the floor.
