Following the events of "The Rise of Skywalker," Poe and BB-8 are forced to make an emergency landing on the volcanic planet Mustafar. There, they encounter the greedy and scheming Graballa the Hutt, who has purchased Darth Vader's castle and is renovating it into the galaxy's first all-inclusive Sith-inspired luxury hotel. While waiting for his X-wing to be repaired, Poe, BB-8, Graballa, and Dean—a brave and spirited young boy who works as Graballa's mechanic—venture deep into the mysterious castle alongside Vader's loyal servant, Vaneé. Along the journey, Vaneé recounts three chilling tales connected to ancient artifacts and iconic villains from across all eras of Star Wars. As Vaneé weaves his stories and draws the heroes further into the castle's shadowy depths, a sinister plot unfolds. With Dean's help, Poe and BB-8 must confront their fears, prevent an ancient evil from awakening, and find a way to escape and reunite with their friends.
