Knightmare is a music track that is unlocked at the Black Knights' Fortress. It is also played during the escape from Keep Le Faye during the King's Ransom quest.
Prior to an update on 28 April 2021, the track could be unlocked in a small area around the fortress, and would keep playing anywhere within the same 64x64 tile square, even when walking outside of the unlock area. Leaving the 64x64 tile area would cause the normal track to start playing again.
- The name of the song is a pun on the word "nightmare".
