Erebus, the ancient greek deity of darkness. Originally imprisoned by the Archangels for being too great a threat to be left free. Now that every angel besides Metatron has been banished, he is slowly breaking free of his prison. Everywhere there is darkness and shadows he can see, and if fully freed, can shape the very fabric of reality like clay. He can only be killed by an Archangel blade dipped in the blood of four Pagan gods, Pontus, the greek personification of the sea, Aethereius, the greek deity of the heavens, Selene, the greek goddess of the Moon, and Helios, the greek god of the Sun. Even then, he must be stabbed in his heart, where it is impossible for any being, whether Angel, Demon, or Pagan god to see.
