Mercurius

Mercurius occupies Seat XIII, an ominous magician and alchemist who created Ewigkeit and established the Obsidian Round Table. He transformed the LDO from occult-minded elite officers into a force of genuine demons and is the Table leader's sworn friend and match in power. Though he can be seen as a mentor or father figure, most LDO members shun him, and his whereabouts have remained unknown for six decades.
