So Darth Vader’s castle is in the new Star Wars movie… how about that, eh!? My kid, upon seeing it, called out “the Tower of Orthanc!” I get that, only the Tower of Orthanc didn’t sit amid treacherous lava rivers on a planet of death and horror. Darth Vader’s home, apparently, does.
Because yes, the castle is on Mustafar, that awful world where the Sith Lord’s final transformation from Anakin Skywalker to Darth Vader took place as he battled Obi-Wan Kenobi and lost several limbs, and his soul, for his trouble. (Oddly, while Rogue One goes out of its way to tag each planet’s name with onscreen titles, Mustafar is not specifically named. But Lucasfilm’s Pablo Hidalgo recently all but confirmed that’s where the castle is located.)
