On the first Life Day after the defeat of the First Order,[a] Rey trains Finn to be a Jedi,[b] but becomes angry with herself for their lack of progress. While reading the ancient Jedi texts for help, Rey finds about a key on the planet Kordoku that she deduces could help her train Finn. With the key only being usable on Life Day, Rey and BB-8 leave for Kordoku, while the rest stay on the planet Kashyyyk, where Poe Dameron unsuccessfully tries to set-up a Life Day party for Chewbacca's family.

Following the events of Star Wars: The Rise of Skywalker, Poe Dameron and BB-8 make an emergency landing on the volcanic planet Mustafar, where they meet Graballa the Hutt. The crime boss 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 plucky and courageous young boy who works as Graballa's mechanic) venture deep into the mysterious castle with Vader's loyal servant, Vaneé. Along the way, Vaneé shares three creepy stories linked to ancient artifacts and iconic villains from across all eras of Star Wars. As Vaneé spins his tales and lures our heroes deeper into the shadowy underbelly of the castle, a sinister plan emerges. With the help of Dean, Poe and BB-8 will have to face their fears, stop an ancient evil from rising, and escape to make it back to their friends.
