After crashlanding on Mustafar, Poe Dameron and BB-8 visit Castle Vader, the galaxy's "first all-inclusive, Sith-inspired, luxury resort." Darth Vader's servant Vaneé regales his guests with "three Sith-inspired stories: "The Lost Boy" the story of how a young Ben Solo first meets Ren and his Knights of Ren; "The Dueling Monstrosities," which imagines how Darth Maul and General Grievous were reborn; and "The Wookiee's Paw," which gives a look at what might have been if all of Luke Skywalker's greatest wishes were immediately granted
