I was inspired by some meta on Tumblr. There is a lot of talk about what the Knights of Ren can be//where, but I don;t think I have read anything where they were ex-stormtroopers, identified by Snoke and Kylo as Force Sensitive and transferred to work directly under Kylo Ren.

You can include Finn if you guys want (him learning that could have happened to him or in an AU where he does have to join the Knights of Ren before leaving).
