In my game, Luis Aspir is a werewolf.
A very musically inclined werewolf.
He spends the nights playing dark piano concertos for himself and the cat.
During the day, the rest of the family takes over, and the piano is used for cheery tunes and dancing.
But soon night falls again, and Pauline goes to bed with a book, and her grandfather's soulful pianoplaying coming from the hall outside her room.
