Star Wars: Galaxy’s Edge will have everything you’d ever want from a theme park, exciting attractions, delicious food, beautiful scenery and killer merch. It will also have everything you’d ever want from actually being inside a Star Wars movie. Aliens, droids, the Millennium Falcon, blue milk, and of course, lightsabers. We already knew that the new land would let you build your own lightsaber, but new details about exactly how it works will make the experience even cooler than we thought, because the shop is actually designed to be a secret.
You see, Star Wars: Galaxy’s Edge isn’t really a theme park land. It’s actually the alien planet of Batuu. While the Resistance has a stronghold on Batuu, the First Order has also taken up residence, and, as you might guess, the First Order doesn’t take kindly to somebody selling lightsabers. This is why the shop that sells the Jedi device is, according to the sign, actually Savi & Son Salvage. At least, that’s what the sign says if you translate it from Aurebesh.
Now, you can walk into Star Traders in Tomorrowland at Disneyland and build a plastic lightsaber right now, but what’s going on inside Savi’s is something entirely different. A finished hilt here is going to run you somewhere around $109 and if you want to add a blade, then also add $50 to the price tag. On the plus side, however, these things will apparently be the real deal, well constructed pieces you get to mix and match to create your own custom device, likely making them worth the price for the serious Star Wars fan.
