Well, Disney just upped the ante with a NEW way to customize your lightsaber and holocrons! The kyber crystal is the force behind any lightsaber and holocron. At Galaxy’s Edge, you can choose the color of your kyber crystal to fit your mood and display what side of the force you represent. Are you on the Dark Side or a Jedi fighting with the Resistance? You can represent your choice with kyber crystals. The crystals customize your lightsaber AND allow you to interact with a holocron!
