In the very first teaser for The Rise of Skywalker, the final shot was a revelation of the ruins of the second Death Star!
Since then, of course, we’ve seen these ruins in plenty of other media, including the most recent trailer for the film. And since we knew that the second Death Star was destroyed at Endor, most people just assumed that this ocean planet was Endor (even though it didn’t look like the Endor we know).
But it’s not. The planet is actually called Kef Bir.
Disney Parks officially announced this week that the popular Star Tours ride will receive an update later this year visiting new planets from The Rise of Skywalker, including “the ocean moon Kef Bir”, confirming that this is indeed the planet on which we see the remains of the Death Star.
So what does this mean? Well, I actually think it’s probably pretty simple – I would guess that Kef Bir is just another moon of Endor. My best guess is that the forest moon of Endor is one of those moons (the one on which the shield generator was located) and that Kef Bir is another one of those moons (the one on which the wreckage of the Death Star fell). In fact, according to Wookieepedia, Endor (the planet) had nine moons, of which Endor (the moon) was the biggest. So I don’t think there needs to be any elaborate theories about these ruins getting here; I think that Kef Bir is probably just another of Endor’s moons.
One other thing about Kef Bir is that it seems likely to be the homeworld of Jannah, one of the main new characters we’ll meet in The Rise of Skywalker.
