Star Wars has just set up a whole new lightsaber form, one that could appear in live-action in less than three months. Although the lightsaber is believed to be older than the Jedi, this mystical kyber-powered weapon has become associated with both the Jedi and the Sith. Every lightsaber blade is unique, not least because the wielder bonds with the kyber crystal within it. Using a lightsaber is more like channeling a live current than swinging a blade.
