Notes

1. It is possible that "Ritual (Nowhere)" was originally intended to play in the room in Nowhere with the six-plate door, since that room resembles the room with the five-lock door where the first "Ritual" track plays.
2. The OST track "The Promise" was based on the middle section of Prelude Op. 28 no. 15 by Frédéric Chopin, which is also played in its original form in the introduction cutscene after Elster picks up The King in Yellow.
3. It seems that "Warm Light" was used in the instruction manual screen in previous versions, when it was possible to access the instruction manual from the main menu. As of PC version 1.2.2, the instruction manual can only be accessed from the in-game pause menu, and it doesn't have dedicated background music.
