«The Ninth Jedi» (Japanese: 九人目のジェダイ) is an animated short film and episode of the web television series Star Wars: Visions. Produced by Production IG, the short premiered on Disney+ on September 22, 2021.
The Ninth Jedi is the 5th episode of Star Wars: Visions, and takes us far past the events of Star Wars Episode 9, the Rise of Skywalker, to a time where the Jedi order are all but forgotten, and their iconic weapon, the lightsaber has been lost to the galaxy. That is except for one brave lightsaber smith, and his daughter, who are attempting to keep the legacy of the order alive.
During this time, the Jedi are hunted to the point of near extinction, with Acolytes of the Sith remaining to quell any Jedi who may rise up.
So, number 1 is that the Kyber crystals being used for the creation of the lightsabers come from asteroids. This idea that Kyber crystals can be formed on an asteroid actually comes from Rogue One: A Star Wars story, where the reason for Jedha’s huge concentration of Kyber crystals is because a large amount of them rain down on the planet every day.
