On the Sith planet Exegol, Palpatine has been maintained alive and reveals to
Kylo Ren his secret armada of Star Destroyers. He orders Kylo to go and kill
Rey. In the meanwhile, the rebels learn about Palpatine's presence on Exegol.
Rey, Poe, Finn and their friends leave for Pasaana where Luke's search for
Exegol had ended. They meet Lando Calrissian who tells them they need a Sith
wayfinder to find Exegol. They then discover, in the remains of a Jedi hunter
ship, a Sith dagger on which C-3PO reads the location of the wayfinder.
Kylo's men however take the dagger. Since C-3PO's programming forbids him to
translate Sith languages, they go to Kijimi to get a hacker read the droid's
memory and learn that the wayfinder is on the wreck of the Deathstar on
Endor's moon Kef Bir. Rey and her friends infiltrate Kylo's Star Destroyer and
recover the dagger; she also confronts Kylo who reveals that she's Palpatine's
granddaughter. On Kef Bir, she fails to obtain the wayfinder, confronts Kylo
again and eventually turns him away from the Dark Side (with the influence of
Leia' dying spirit and a memory of his father, Solo, Kylo becomes Ben Solo
again). She leaves the moon with Kylo's ship (which also contains a wayfinder)
and exiles herself to Ahch-To after having had a vision of herself on
Palpatine's throne. The spirit of Luke convinces her to confront Palpatine,
and she leaves for Exegol with Luke's X-Wing. Rey then sends the Resistance a
message with the coordinates of Exegol and she confronts Palpatine.
