Known as the "original sin" and the son of Ignora, Lucifer was born after the destruction of the angels' home-world, making him part of the second generation of his kind. Once an honored and revered archangel, he was tasked with the responsibility of leading the archangels. Lucifer eventually abandoned his job, feeling it was too boring in heaven for him to remain. Losing his former status and gaining black wings signifying his corruption, his powers became demonic, reclassifying him a fallen angel. Lucifer traveled to the Demon Realm where he would remain for several years. During his time among the warring demonic tribes, Lucifer gained a certain amount of power and influence over his new compatriots, though was still not considered a "pure" demon due to his celestial origins. He would later join the young Satan Jacob in his plot to unite the demon realm under his flag, the rising monarch proclaiming that Lucifer should feel free to kill him if he ever felt displeased with his leadership.
