The Knights of Ren are an enclave of masked warriors who move through the galaxy as raiders, enforcers, and collectors of violence. Their distinct weapons and armor make them recognizable as a group, but their greater power comes from the uncertainty surrounding their origins and their code.

The Knights are not presented as a conventional Jedi order or a formal Sith lineage. They follow the way of Ren, a philosophy built around power, fear, and the freedom to take what they want. That position places them outside the old institutions while still drawing on the dark side’s language of domination.
Ben Solo becomes Kylo Ren and takes command of the group, turning the Knights into instruments of the First Order. Their return brings an older form of marauding violence into the final conflict, where loyalty to a leader matters more to them than any public political program.
As a character subject, the Knights of Ren work as a visual collective. Helmets, blades, blasters, and the Night Buzzard give the group a strong identity even when individual members remain deliberately difficult to separate from one another.
Collector note: Knights of Ren cards are defined by the full group, their individual helmets and weapons, the Night Buzzard, and their connection to Kylo Ren in The Rise of Skywalker.
