Star Wars: The Rise of Skywalker concept artist Matthew Savage has shared a new look at the mechanics of Rey's lightsaber. At the end of the movie, she dubbed herself "Rey Skywalker" much to the chagrin of Star Wars fans, but the sight of her igniting that yellow blade was still pretty cool.
As you can see below, we now have a much better idea of how Rey turned her staff into the ancient Jedi weapon, and while it wasn't used in the film itself, we can see both the inner workings and where the Kyber Crystal was housed (where Rey found that has never actually been revealed).
Lucasfilm's creative art manager, Phil Szostak also weighed in, explaining: "The lightsaber was going to be in more than just one shot at the end. There was going to be a subplot throughout the film showing Rey working on it at her bench, using the Jedi texts as a guide."
That didn't make the cut of the already busy movie, of course, and with no sign of deleted scenes, who knows if it was even shot. We may never know for certain, but for now, you can check out this artwork below:
