Knights of Ren (Earth-2042)

"Well, I'm Jerec. These are the Knights of Ren. And we're legendary."

- Jerec

The Knights of Ren is an enclave of Force-sensitive warriors who served Kylo Ren—master of the Knights of Ren and Supreme Leader of the First Order —during the New Republic Era. They are Force-sensitive adepts that emerged to fill the void left by the demise of the last Sith Lords. Adhering to the ways of the Ren, a philosophy epitomized by the lightsaber, the Knights roamed the galaxy causing wanton destruction as devotees of the dark side of the Force. Armed with distinctive weapons for ranged and close-quarter combat, they are the fearsome enforcers of their master's will.
