Trying my hand at a super long fic... I'll update when I can but for now here's the prologue. Sorry it's short, hopefully I'll have the next chapter up ASAP. I don't own Harry Potter or Bach. All chapters will probably be named after classical piano pieces, because of reasons.

The castle looks loneliest at night.
That's how Lily thought of it, at least, with its towers dark against a darker sky and windows empty of torchlight. Her frozen hands clutched the front of the Firebolt as she hovered far above the Quidditch pitch. The clock struck midnight.
She was supposed to be in bed.
She blamed her brothers.
The slight wind nudged her into another meandering lap. James wasn't very careful that night, putting away the map and cloak. And Albus had encouraged her to practice. Really, what did they expect?
True, she was only a second year. Lily supposed that even her father would be surprised at how many nights she spent decidedly not in the Gryffindor Dormitory.
Her favorite stories had always been of the Forbidden Forest. "Daddy, what about the time you and Uncle Ron were attacked by spiders?" Despite the tales of near-death experiences and the warning that students were meant to stay out, the Forbidden Forest maintained an air of dark and mysterious innocence.
It was not a secret that Lily Potter liked dark things.
One flight over the forest, she promised herself. Then I can go to sleep.
She was about to turn back when she heard it- the cry for help. And it was too bad, really, because anyone who knew her at Hogwarts would tell you that aside from being deep and morbidly inclined, never has she behaved selfishly or unkindly toward anyone. So it was without thinking that she angled her broom downward and searched the forest for the source of the shout.
The light of the full moon shone bright against the pool of blood
