Elohim

Elohim is an ancient Dark Mage of great power. 200 years ago after witnessing the power of Zeref, Elohim now desires to acquire the man's secrets in order to achieve his final goal of true immortality. To do this he captured one of Zeref's Etherious, Geist and made him hunt down his own kind for Elohim's uses. He also took in a survivor of a demon attack, Lucida Venator and taught her the way of Iron Devil Slayer Magic.
