Renegade Knights are knights devoted to serving the evil sorceress Morgan Le Faye. They imprisoned the Knights of the Round Table and Merlin during King's Ransom. They can be accessed by taking the crate behind the candle shop in Catherby after the quest Merlin's Crystal.
- Despite being Saradominists they seem to follow the moral codes of Zamorak (strength through chaos), or may simply have a corrupted vision of their religion, somewhat like HAM members.
- They appear to be wearing a similar outfit to the Varrockian Guard. They are equipped with a dark version of the helm and sash (around the waist), as well as wielding a similar short-sword.
- During the King's Ransom quest, if you talk to Sir Lancelot while he is fighting the Renegade Knights, a Renegade Knight will plead for mercy in the conversation.
