Maid of Sker

There are 30 notes in the game, you get the first one automatically. All others can be gotten whenever you choose to get them. None of them are missable. But in this general order you can get them as the plot progresses.

(If you're having trouble with enemies I would recommend going to a save room, saving, and then loading from last save. Loading a save resets enemies back to their spawn points so you can sneak around easier.)
