Knights of Ren fully revealed in Empire Magazine - Star Wars: The Rise of Skywalker 1

The Knights of Ren were a mysterious order of elite warriors that followed the dark side of the Force in an age when the Sith were extinct and the Jedi Order was all but destroyed. They were neither Jedi Knights nor Sith Lords, but members of a new generation of Force warriors that emerged prior to the slaughter of Jedi MasterLuke Skywalker‘s apprentices, the most promising of which was Kylo Ren. Seduced by the power of the dark side, the former Ben Solo renounced the Jedi and adopted a new name in addition to the title master of the Knights of Ren, becoming Supreme LeaderSnoke‘s disciple and a warlord of the First Order. Under Snoke’s guidance, the Knights of Ren filled the vacuum left by the demise of Kylo’s grandfather, Darth Vader, the last Sith Lord. Ren, who earned the nickname «Jedi Killer» by destroying the generation of Jedi trained by Skywalker, was determined to destroy the last Jedi and fulfill his grandfather’s legacy.
