- "Even you, master of the Knights of Ren, have never faced such a test."
- ―Supreme Leader Snoke, to Kylo Ren
The Knights of Ren included Kylo Ren, whom Supreme Leader Snoke, the leader of these forces of darkness, referred to as a master of the Knights of Ren. As a member of the Knights of Ren, Kylo was not part of the formal hierarchy of the First Order but nonetheless operated with freedom among the military command, who tolerated his presence with some hesitation as his agenda trumped their own. Kylo wore a black and silver combat helmet based on the battle gear worn by the Knights of Ren.
The Knights of Ren operated in the decades following the Galactic Civil War. They were under the command of Supreme Leader Snoke, who used them as a tool of the dark side of the Force alongside the First Order. Rey, a Force-sensitive scavenger who hailed from Jakku, saw the Knights of Ren in a vision.
