Arch-demon

One hundred sixty-five years ago, God stopped the war between angels and demons. To show that there was peace, the archangel Michael and Lucifer built a school so that the children could learn to respect one another. So with no more war, Lucifer had a son with his wife Lilith, and since Lucifer was an archangel, this child was the first of his kind, half archangel half demon. This child's name was Mordred.
