Iblis

Iblis as known in Islamic Lore, he was vain and haughty. He could never accept Adam was more Beautiful and a Higher Creature. He made himself incarnate wherever Adam and Eve was, and paired with di-ni to destroy Adam and Eve's Marriage by taking over their Light Information. Because they wanted the other. They were both previous adulterers who would go to Hell, pay for their crimes, and re-incarnate for another chance. He was Lucifer.
