We learned two big things from the Lucasfilm Publishing panel at SDCC: There’s going to be a prequel comic about Kylo and the Knights of Ren, and Dooku: Jedi Lost is indeed coming out in hardcover.
Charles Soule’s four-issue The Rise of Kylo Ren is “the one story everyone’s dying to see, about Kylo and the Knights of Ren? That’s this.” It will be out in December.
Two other The Rise of Skywalker tie-in comics – IDW’s post-The Last Jedi Chewbacca storyline and Marvel’s Allegiance – were announced earlier. We also learned that Force Collector will have some sort of connection to Galaxy’s Edge and Batuu, and Pablo’s latest Visual Guide will feature a Knight of Ren on the cover.
Jedi-Bibliothek was first to provide nice, high res versions of the book covers revealed at the panel. Here are the two most relevant to our interests:
And, thanks to Penguin Random House, here’s video of the Publishing panel! They also have the one on audiobooks if that’s your jam.
