A Force of Wills
As the jedi and the criminals all attacked one another, Luke shifted the holocron from his artificial hand to his real one. As soon as the crystal touched his flesh, it began to glow with an eerie red light.
"Hey, what's that?" Luke asked as the glowing light engulfed him. "What's going on?"
The next moment, Skywalker found himself standing on an asteroid floating in the middle of space. All around him he could see all the stars of the galaxy and he felt the movement of comets and rotation of planets as if they were a part of him.
"Uh... what is happening?" Luke asked in disbelief. "How can I breathe in space?"
"You are not in space, Skywalker." A familiar voice hissed. "But rather within the holocron itself and the confines of your own mind."
"Oh great, one of those force vision things, Obi-wan told me about." Luke groaned. "Alright, Sidious. You might as well reveal yourself." A cloaked and hooded figure emerged from the darkness, smiling a hideous grin as the jedi master.
"I never expected you to come here, boy. This holocron was meant for the training of sith in case the plans of the Order of Two failed."
"Well, then. Looks like this thing will be needed." Luke smiled, smugly. "You died aboard the second Death Star killed by the very apprentice you trained to destroy the jedi."
"I always knew your father had a sliver of the light still within him." Palpatine snarled, pulling a lightsaber from beneath his robes. "Once I have deposed of you, the holocron will fall into the hands of one of your curious students and the cycle will begin anew."
"No." Luke stated, firmly drawing his own blade. "The legacy of Darth Bane ends here and now." He took a fighting stance. "I'm going to destroy this echo you left of yourself in the holocron."
"Am I an echo or am I not?" Palpatine goated the jedi. "Perhaps, my mind survives in the holocron, a spirit bound to its crystal body."
"It doesn't matter." Luke replied. "Once I destroy this thing, you'll fade into chaos nonetheless."
"Very well, jedi. Face me as many of your order had done before." The sith snarled. "Let this be our final battle."
At that the two force users lunged at each other, red and green lightsaber blades swung wildly smashing into each other and creating sparks again and again. Luke force pushed the sith lord backwards but Sidious reached out and began to force choke Luke.
"What's the matter, boy? Can't breath?" Sidious laughed, clenching his right hand. "Don't choke on your own self-righteousness."
Luke used the force to fling a rock at Palpatine's forehead but the sith lord continued to choke him. Reaching out with his own hand, Luke force choked the Emperor right back until both exhausted warriors drop back to the ground.
"Very clever, welp. You are strong in the Force." Palpatine stood up again. "But even with all that power there are certain things even a jedi can not do." Sidious unleashed a hail of lightning from his fingers, starting to fry Skywalker just as he had on the second Death Star. But this time, Luke raised his green lightsaber blocking the lightning and sending it right back at the sith lord. "AAH!" He screamed, stumbling backwards. "You'll pay for that, boy." Slamming his fist into the ground, Palpatine send a shock wave towards Luke that knocked him clean off his feet.
"That's impossible." Luke exclaimed, trying to stand up again. "No force power works like that."
"Luke, hear me." There was a glow beside the jedi as a familiar bearded elderly man appeared. "You are inside of the holocron. Here your thoughts become reality. Use it to your advantage."
"Thanks, Ben." Luke bowed to his former master who disappeared.
Raising his hands, Luke materialized his fathers blue lightsaber in his other hand and fired two energy beams from the two blades. Hitting Darth Sidious dead center and sending him flying backwards into the stone.
"Bah, you think you can defeat me with your cheap jedi tricks?" The emperor's hands began to glow. "I will call up an army of the past who will crush you into cosmic dust." Palpatine summoned several figures up from the ground around him. A solid image of Darth Maul, Count Dooku, General Grievous, Darth Vader, and an endless army of stromtroopers stood behind Palpatine. "How are you going to defeat this?"
"The jedi will defeat you, Darth Sidious." Luke closed his eyes and concentrated. "Even those you have murdered, we will all do this... together." Behind Luke emerged Anakin Skywalker, a young Obi-wan, Mace Windu, Yoda, and all the other jedi and behind them an endless army of clone troopers. "You're going to pay for what you did to the jedi and the Republic."
The two armies plowed into each other: Anakin Skywalker crossing sabers with Darth Vader.
"You can not escape me, Skywalker." Vader hissed. "I am your future."
"No," Anakin replied, driving the iron demon back." You are my past."
"Let's go, boys." A ghostly Rex called out. "Let's show these tin heads what the 501st can do." The fight seemed evenly matched even as warriors fell on both sides.
General Griveous managed to strike down Obi-wan but was cut down by Mace Windu. The storm troopers slowly gave way before their superior clone counterparts. Out of the corner of his eye, Luke saw Count Dooku struck down by Qui-gon Jinn.
"Luke, we can't hold this forever." Jinn called out. "Take the fight to Palpatine directly."
"You think you can defeat me, child?" Sidious held up his arms and began to grow to a gigantic size. "I will crush you under my feet." The sith lord brought his foot down on top of Luke who barely rolled out of the way. Closing his own eyes, Luke grew to the same towering height as the Emperor.
"Alright, Sheev Palpatine. If it's a fight you want," He pulled his fist up. "Then, it's a fight you'll get." Reaching behind him, Luke grabbed a comet and hurled it at the sith lord. The ball of ice shattered against the Emperor's robes sending him reeling off the asteroid. In anger, the floating Palpatine began to hurl several other comets back at Luke.
"You can not defeat the Sith." Sidious boasted. "With our power, we command the comets and the very planets themselves. Through the dark side., the galaxy is our plaything to control."
"We'll see about that." Luke replied, jumping off the asteroid. Reaching out through space. Skywalker grabbed Tatooine and hurled the sphere at the Emperor who was knocked back by the giant rock. Sidious then grabbed Bespin and flung the gas giant at the giant Luke.
"So, you want to take this battle over the top, Skywalker?" The Emperor roared. "I will crush you beneath the rings of Kessel. He grew to a size larger than the galaxy. The fight then moved to a size beyond the size the universe." The opponent hurled planets and quasars at one another, smashing heavenly bodies into each other. Luke had just hurled Coruscant and dodge Naboo when the Emperor goated him again.
"Why don't you just give this up, Skywalker?"He snarled, unleashing a powerful ball of force energy at his opponent. "I was around long before you were ever born and I will be here long after you are gone."
"You're nothing but a memory, Sidious." Luke replied, catching the force sphere and tossing it back. "A memory I vow to erase from the galaxy forever." As the two titans battled overhead the last remaining jedi defeated the army of storm troopers and Sith. Looking up at the conflict between Luke and Sidious, Yoda decided what he had to do.
"A final sacrifice, we must make." The green alien told the other phantoms. "Destroy Darth Bane's sith, we must here as we failed to do in life."
"Then, let us join together." Mace added. "As the force connects all things." The remaining jedi concentrated, their bodies forming into a tiny black hole. I called up to the giant Luke saying, 'Skywalker, hurl us at the Emperor'. Their voice spoke as one. 'And we shall destroy the Sith forever.' Reaching down to pick up the tiny sphere, Luke hurled it at the Emperor.
"Is that the best you got?" Palpatine laughed. "It seem your out of energy, Skywalker."
"Size matters not, your majesty." Luke replied. "It's you who's out of time."
"What does that mean?" The Emperor asked. Suddenly, he felt his body being pulled into the tiny black sphere as it touch his robe. "This can't be. NOOOOOOOOOO!" Palpatine wailed as he was stretched out to lengthened spaghetti and was sucked into the minuscule black globe.
"Sorry, Sidious." Luke smiled in triumph. "Looks like the Sith's plans for Galactic Conquest just went down the hole."
There was a bright flash of red light and Luke found himself back in the auction hall. the holocron turned dark in his hand and shattered into tiny fragments.
"That's the end of Darth Sidious." Luke said, a satisfied smile on his face. "How are things doing out here?" Luke looked around to see dead criminals all over the room and Naboo security forces all over the place.
"Are you alright?" One of them asked him.
"Yeah." He answered. "I should be fine."
"That's good to know." The security guard answered.
"Hopefully, none of my companions have gotten hurt." Luke replied.
