Mission to Kef Bir

In 35 ABY, the Jedi apprentice Rey and her companions, Chewbacca, Poe Dameron and Finn, undertook a mission to the Kef Bir moon in the Endor system. Having acquired a Sith relic at Kijimi, the Resistance team discovered the location of the wayfinder that belonged to the former Galactic Emperor and Dark Lord of the Sith Darth Sidious. Determined to gain the object that would lead them to the Sith world of Exegol, Rey entered the ruins of the DS-2 Death Star II Mobile Battle Station alone and found the wayfinder in the Emperor's Throne Room.

However, Rey was followed to Kef Bir by Supreme Leader of the First Order Kylo Ren, who destroyed the wayfinder in the hope of pushing the former scavenger to the dark side of the Force. A lightsaber duel ensued between Ren and Rey, the grandson of Darth Vader and the granddaughter of Darth Sidious, respectively. During the fight, Ren's focus wavered as he sensed the death of his mother, Princess Leia Organa, across the galaxy, allowing Rey to pierce him with his own lightsaber. Realizing that anger had driven her actions, Rey used the Force to heal Ren before departing from Kef Bir, seeking exile on Ahch-To. The connection between them, along with the loss of Ren's mother and the memory of his father, Han Solo, ultimately restored Ben Solo to the light side of the Force.
