From what I understand, another angel did a spell to make the ones in Heaven fall to Earth. And the ones who survived the fall and found human vessels were either killed in various ways for various reasons or they lived long enough to reclaim Heaven. It must be safe where you came from. I had to grow up fast after I was born.
My father was the devil, he's dead now. Speaking as a child of Lucifer, I wasn't interested in having Lucifer as a father.
