- The name of the song is a pun on the word "nightmare".
- It is also a reference, when combined with the "Black Knights" to the anime Code Geass, in which the protagonist's faction is called "the Black Knights" and there are machines called "Knightmares"
- After an update, this track only plays in the basement of the fortress.
