mother

she's a dark angel, an angel that once was good and pure, but she fell in love with satan and became a dark angel. they ended up having a baby girl (you, sorry boys) but had to hide you from thise who would harm you, so you grew up in the mortal world as an orphan. you had a strange childhood living in an orphanage, a demon would look over you and protect you, and you would often sleep in a nearby graveyard, next to a old statue of an angel. once you grew older you wanted answers and set out to find them, investigating haunted places with some new friends, eventually you investigated a place and as a condition you had to all have an exorcism after, this caused you a lot of pain of suffering and you left the church after, running into a dark angel, your mother.
