Rey's Star Destroyer exited hyperspace in the Korriban system. The ancient Sith world was nearly devoid of life as the Dark Side had poisoned the soil and every living thing. As the Star Destroyer approached the desert mountainous planet, Rey could feel the Dark Side of the Force. It was calling to her.
"I will go down to the surface alone with K-2," Rey told her captain.
"Korriban is a hostile world, my Empress," he protested.
"It's too dangerous for anyone else to come with me," Rey explained.
"As you wish. I will prepare your shuttle," the captain said obediently.
The shuttle exited the Star Destroyer and went down to the planet near the valley of Sith Lord tombs. K-2, her droid, was there to pilot for her. The shuttle landed and the two ventured out. Rey put on a headdress and scarf over her face as the winds picked up.
"What is the purpose of coming here if I may ask?" K-2 asked her.
"I want answers about my parents. Since they escaped from Kessel, the trail has gone cold," Rey told it.
"Your obsession with your parents is most confusing. I never cared where I was manufactured," K-2 said as the two continued to stroll.
Rey smiled. "If you had a damaged part and the only place to fix you was your original manufacturer, you would want to know where they were."
"I suppose so," K-2 allowed.
A Korriban beast approached Rey hungrily and charged the two of them. Rey immediately ignited her blue light saber to defend herself. K-2 raised his arms and began firing continuously on the beast dropping it before it could even get close.
"I think that's enough," Rey said to the droid.
"It's not dead," K-2 warned her.
"I know. We don't need to kill it," she said as she got closer to the wounded beast.
"We don't?" the droid wondered.
Rey kept her light saber up as she approached the moaning beast. It had been hit several times but was still alive. It attempted to either flee or strike at her but couldn't move. "It was only doing what it was meant to do," Rey said of the beast.
"That's not reassuring," K-2 replied.
Rey focused on the Force and gradually healed the beast's wounds. The beast eyed Rey as it was completely healed. For the first time, the beast felt human kindness. As soon as the beast was healed, it tried to attack her. K-2 immediately shot the beast in the head killing it.
Rey stared at the beast stunned. "Are we learning yet?" the droid asked sarcastically.
Rey then heard a voice in the wind calling out to her. "Peace is a lie," it said to her in a laughing mocking voice. "Did you hear that?" Rey asked the droid.
"No," the droid said giving her a curious look.
"Let's go," Rey said walking past the dead beast.
Kylo Ren ordered the Supremacy fleet to Yavin 4. Upon arriving at the forest moon, he faced no resistance. A hologram of the moon appeared on the bridge showing the moon's continents and oceans. Kylo studied the map not finding what he was looking for.
"According to the Empire's archives, there is a lost subterranean city on the moon. I want no effort spared to find it," Kylo ordered.
"As you wish, Supreme Leader," his admiral said without question.
Rey entered a Sith tomb and used her light saber to light her way through it. K-2 switched to red vision as it scanned the dark corridors. Reptilian flying creatures hungrily flew at her. Rey swiped at them with her light saber as K-2 fired on them. They then heard a noise as a dark figure approached them.
"Why do you disturb my tomb?" the dark figure asked. He was dressed in Sith ceremonial armor that he had been buried in.
"I've come to learn about my parents," Rey said to it.
"How amusing…Jedi do not care about such things. For thousands of years, the Jedi took children from their parents to avoid attachment and family pride," the dark figure chuckled.
"I'm not like the Jedi you have faced before," Rey said to him.
The dark figure laughed. "I sense you have neither knowledge nor wisdom, but you do have strength. Tell me, what has become of the Sith Order?" the dark figure asked.
"Kylo Ren is now Supreme Leader," Rey felt compelled to answer.
"And who is his apprentice?" the dark figure asked.
"He has none. He killed his master and now the two of us work together," Rey said boldly.
"A Sith and a Jedi together?" the dark figure scoffed. "It was I, Darth Bane, who established the rule of two. The Sith killed each other, victims of their own greed, but from the ashes I was the last survivor. I passed on my knowledge to only one and built a legacy that has lasted for two thousand years," Darth Bane said to her.
"That legacy has ended. During all those years, masters and apprentices have killed one another in mutual distrust. Now, the two of us will bring balance to the Force," Rey said confidently.
Darth Bane laughed at her. "For how long can you keep up this game of yours, child? Can you live for all eternity? When you die, will another Jedi take your place?"
"After us, the Sith and the Jedi will be no more," Rey replied.
"As long as these tombs remain, there will always be one that will call themselves Sith," Darth Bane doubted.
"I know," Rey said softly. She raised her hands to pull the entire tomb down.
"No!" Darth Bane shouted at her.
"Tell me where I can find Darth Sideous," Rey demanded quickly.
"Spare the tomb, and I will show you," Darth Bane offered.
Kylo landed on the forest moon in his Tie prototype fighter. As he went outside, he could see AT-ST walkers and Storm troopers searching. Taking a speeder from his fighter, Kylo made his way to an ancient temple. Looking inside, he saw the remains of an old Rebel Alliance base. Kylo strolled through the base and saw a Force echo of his mother, C-3PO, and other Alliance leaders huddled together as they heard reports of their attack on the first Death Star.
"Did you ever wonder what would happen if you won the war?" Kylo asked the young Leia.
Kylo then visited the old hanger bay. Only scrap metal from destroyed X-wings remained. He could see his parents celebrating with his uncle Luke after their victory against the Empire. Kylo closed his eyes in pain as he saw their jubilant faces. Leaving the temple, Kylo brought his wrist communicator to his mouth.
"Fire on this position," he ordered, his voice cracking.
Kylo then saw the Supremacy fire on the temple completely destroying it. He watched the temple collapse and what remained of the Rebel Alliance base went with it. "Supreme Leader, we've found it," his wrist communicator told him.
Rey followed the Force ghost of Darth Bane to another tomb deep inside the structure. Darth Bane then disappeared as she entered. Looking up, she saw a throne with an empty stone casket in front of it. On the throne was a dark figure with piercing yellow eyes.
"Darth Sideous," Rey addressed.
"I know you. You are a descendent of mine," Sideous said not moving from his throne.
"I want to know what happened to your son," Rey demanded.
"I had him sent to prison on Kessel and forced him to build weapons for me," Sideous replied.
"Why would you do that to your own son?" Rey asked angrily.
"I wanted him to be my new apprentice, but he had neither the will nor the strength. He was a pacifist and an embarrassment to me. He married a Jedi princess from Yavin in secret, but I quickly found out. I found them and made them suffer," Sideous said maliciously.
"Did you kill them?" Rey asked accusingly.
"Oh, no," Sideous mocked. "It was the Alliance."
Kylo Ren led an army of Storm troopers inside the subterranean city. The city featured skyscrapers that nearly reached the ceiling of the large cave structure. On top of the towers were artificial light sources to simulate sun light. As soon as the invading army entered the city, the humanoid droid inhabitants took notice.
"Destroy the droids and find me the master computer," Kylo ordered.
Storm troopers swarmed the city streets firing on every droid they could find. Kylo then received a hologram map of the entire city. Marching to the center of the city, Kylo used his light saber to slash open the secure doors leading to the master computer.
Kylo easily slashed apart the droids guarding the computer and then accessed the ancient keyboard. "Tell me everything about spirit possession," Kylo ordered the computer.
"Access forbidden," the computer refused.
"Give me access or I will destroy the entire archive," Kylo threatened.
"Access granted," the computer said and then began loading the relevant files.
In a vision, Rey could see the Battle of Jakku. The Imperial armada made up two dozen Star Destroyers and the Super Star Destroyer, Ravager. The Alliance exited hyperspace with a combination of fighters, corvettes, transport ships, frigates, Mon Calmari cruisers, and three Starhawk battleships. Admiral Ackbar was on the bridge of Home One with Leia Organa at his side.
The Millennium Falcon piloted by Han Solo and Chewbacca went to work to protect Alliance ships from Tie fighters. Luke Skywalker and Wedge Antilles expertly led squadrons against the Tie fighter swarms. The Alliance fleet opened fire on the Imperials but the Ravager was shielded by the Star Destroyers.
"Concentrate all fire on the center," Admiral Ackbar ordered.
The Millennium Falcon and X-wings engaged the central Star Destroyer blasting out its shield generators and heavily damaging its hull with concussion bombs. The Star Destroyer captain panicked and attempted to flee the battle line. The Star Destroyer was shredded as it tried to escape. The Alliance ships then started firing on Ravager with the hole they had made in the Imperial defenses.
A critically damaged Mon Calmari cruiser went straight for the Ravager but the Super Star Destroyer was able to avoid it just in time. As the Alliance cruiser entered Jakku's atmosphere, it activated its own tractor beam taking the Ravager down with it. The massive ship became tilted with the bow facing the planet.
"Target the Ravager's engines," Admiral Ackbar ordered.
Alliance ships and fighters destroyed several of the Super Star Destroyers engines causing it to fall into Jakku's atmosphere. The atmosphere caused the Ravager to burn and then crash into the desert sands of Jakku.
The bridge of Home One cheered as the Ravager was taken out of the battle.
On the surface of Jakku, Rey's parents placed the young and crying Rey in the hands of a junk dealer. "We will come back for you. I promise," her mother told her.
Rey continued to cry as she was left behind. Her parents fled in a ship as Alliance fighters engaged AT-AT walkers in the sands. Luke's X-wing gave chase to the fleeing ship but then disengaged when he didn't feel anything sinister from it.
Leia felt a tremor as the fleeing ship tried to escape the space battle. "Admiral, that's the ship we have been looking for," Leia said to Ackbar.
Ackbar looked at his instrument panel. "We cannot allow the son of the Emperor to escape."
"Han, target that ship," Leia said and inputted information into the computer.
"On it," Han replied by radio and went straight for it.
The Falcon and an X-wing squadron chased after the ship and fired on it. The ship attempted to go to light-speed but tractor beams from Alliance ships slowed it down. The Falcon fired on the ship destroying it and killing Rey's parents.
Kylo collected the information he needed on a data stick and then slashed the computer to pieces with his light saber in a sudden rage. He then turned to his Storm troopers. "Destroy it all," he ordered.
Storm troopers blasted the city with flame throwers until the entire city was engulfed in flames. Satisfied with the Lost City's destruction, Kylo went back up to the surface. As he did, he felt something was wrong. He touched his eye with his glove and wiped away a tear. Disturbed by this, Kylo took to his speeder back to his ship.
Rey exited the vision with tears in her eyes. "Rey, I have been thinking of bringing on some more crew," Han had told her. "Are you offering me a job?" Rey asked excitedly back. Rey then recalled how she had embraced Leia shortly after Han's death. How they shared in each other's grief.
Rey clenched her fists as tears fell on the tomb floor. "Yes, my child. I can feel the hate swell in you," Sideous said pleased.
"It's not true," Rey dismissed the vision.
"Search your feelings. You know it to be true," Sideous said to her. "Now, take up my light saber, and I will be with you always."
Rey used the Force to push the casket open and saw Sideou's light saber, the artifact that allowed his spirit to remain in existence. It was this artifact that kept him confined to this tomb like all the others. The tomb was filled with Sith relics that allowed them to still exist as ghosts.
"Together, we will finally end my old master, Darth Plaguies," Sideous said gleefully.
"Snoke," Rey realized. "You were his apprentice."
"He taught me everything about the Force. Only together can we defeat him," Sideous told her.
"Snoke is dead. Kylo Ren killed him," Rey said.
"Oh, no. You're quite mistaken, child. He is very much alive," Sideous sneered.
Rey wasn't sure whether to trust him. If it were true, Kylo Ren would need to be told immediately. "Take it, child," Sideous said to her once more.
Rey took Sideou's light saber and stared at it reflectively. She turned it on and saw the crimson blade that had killed so many. "Good," Sideous smiled.
Rey then turned it off, threw it up into the air, and in a swift motion sliced it in half with her blue light saber. "No!" Sideous screamed at her.
"Sorry, grandfather. Red isn't my color," Rey smirked and then used the Force to collapse the ceiling. Sideous screamed in rage as he was sent to the void never to return.
"I recommend we leave," her droid told her.
"I think you're right," Rey agreed and the two fled the tomb as it started to collapse. Rey and the droid ran out the tomb entrance as the tomb collapsed. Sith Lords of old screamed in rage, as their tombs were destroyed sending them all into the void.
Author's Notes: So, following the theme of Last Jedi, Kylo and Rey are progressively ending the Sith-Jedi Legacy. They both take what they want from the legacies, then betray those legacies, and destroy them. While I revealed that Palpatine was Rey's grandfather, it was also revealed that her parents were essentially nobodies which is technically true according to Legends: Trioculus and Kendalina. However, I decided to keep the whole "three-eyed" father drama out of it. The Alliance being directly responsible for their deaths was to show the complexity of war and that those who you consider allies often reveal themselves to be enemies and vice versa. In accordance with Star Wars tradition, I have had Rey and Kylo stay apart doing their own personal adventures. The intensity of their relationship need not be the length of their screen time together.
