A new four-issue comic mini-series detailing the origins of Kylo Ren and the Knights of Ren will be released by Marvel Comics just before the release of Star Wars: The Rise of Skywalker in December.
The news came during the Lucasfilm publishing panel at San Diego Comic Con 2019 where we learned it’ll be written by Charles Soule, who has also written Marvel’s Darth Vader, Obiwan & Anakin, Lando, and Poe Dameron comics.
