I wasn’t going to have it be Kef Bir, anyways. It’s currently set on the Sanctuary Moon of Endor. I would also appreciate more PT callbacks, but I have some ideas for that which don’t simply involve setting.
One symbolism that I really like about it being set on the Endor from ROTJ is that Vader’s remains were burned there, and Kylo becomes Ben in the water there.
As for why Palps would bring it to the Death Star, he wasn’t expecting it to blow up and was probably thinking it would be his new place of residence.
