You were a parent figure to a lot of archangels and angels, because you were a seraphim who was very close to God... But one specifically, was very close to you and looked up to you a lot... That was Lucifer.

One day, you were sitting in the garden of Eden when Lucifer spotted you. He ran up to you and smiled warmly and happily... But one thing was unsettling. He was covered in golden angel blood...

Lucifer: Mother/father!
