Lucifer Morningstar is a fallen rebel archangel who was cast out of Heaven and onto Earth as punishment for leading the revolt of the angels. Before the DC Verse was created, in the void outside all creations that is the Primal Monitor, Yahweh created two brothers infused with literal unlimited might, Michael Demiurgos and Samael, later called Lucifer Morningstar. After both were formed, Yahweh guided them, instructed them as to how to use their powers, and then they formed the creation we all know as the DC Multiverse.
