Greetings, Robert, and May The Force Be With You!
Welcome to planDisney and thank you for stopping by with your question! How exciting that you have some alternate color kyber crystals! On one of my recent visits to
Black Spire Outpost, I and a couple of my friends were opening kyber crystals and one of them revealed a black crystal! I was immensely envious but recognized that this path would lead me to the Dark Side, so I just congratulated her and refrained from going back into
Dok-Ondar's Den of Antiquities and purchasing more.
I'm afraid that the Gatherers at
Savi's Workshop do not allow Guests to supply their own kyber crystals during the lightsaber building experience. You must use the supplied kyber crystal that is provided during your session. The Gatherers want to provide Guests with a custom lightsaber and a uniform experience for all involved. The Jedi Code emphasizes compassion and it would not do for a Jedi to tempt a fellow Force sensitive Guest with a lightsaber color that they are unable to obtain from Savi's Workshop.
Once you leave Savi's Workshop, however, it's very easy to disassemble your new lightsaber and replace the kyber crystal within! And now you'll have two crystals to go with your lightsaber so you can switch them out to whatever suits your tastes.
Will you be able to make it to the Disneyland Resort during
Season of the Force? Watching the fireworks from Galaxy's Edge with the stirring score of John Williams' music during "Fire of the Rising Moons" is epic! And
Hyperspace Mountain is one of my favorite attraction overlays and should not be missed!
Robert, I hope that this information was useful for you. Please write back to us anytime you have more questions. We'd love to hear from you again! Until next time!
Have a Magical Day!
