You were meditating in your quarters when you sensed Darth Sidious. You looked further and saw he was performing a sith ritual with Dooku. You opened your eyes and jumped up, "Master? where are you going?" Cal asked "stay here Padawan, I'm leaving to face Darth Sidious," you stated "well if you're facing the sith then you should bring me! I-" "no, you're not ready. Do not disobey this order, stay here," you interrupted and ran out.
As you ran through the halls of the temple you came across Yoda. "Master Yoda!" you exclaimed, getting his attention, "Master Skywalker, something you need?" he asked "I sensed Sidious, come on, we have to stop him," you replied and you ran out with him on your back.
You force jumped from building to building, likely scaring several people, and until you reached the industrial district.
You landed and made your way towards a building. Yoda jumped down and the door opened. You could see the two sith lords. "Jedi scum," Dooku snarled as he stepped away from the cauldron and activated his lightsaber, you activated your own and got in a ready pose. He lunged at you and you blocked with ease. You knew Dooku was drawing power from the ritual and the several sith relics around the room, so he would likely be at a similar strength as to on Korriban. You on the other hand, was doing the exact same thing, and battling for control of the dark side with Sidious. You jumped over another swing and swung at his wrist, however Dooku spun around and went for your arm. Although you reacted quickly enough and stopped it with the force.
Meanwhile with Yoda and Sidious. "Darth Sidious, meet at last we do," Yoda said as he drew his lightsaber "you really think you're enough to defeat me? alone?" Sidious laughed "alone I am not, the force, with me it is," Yoda replied and jumped at the sith lord. Sidious quickly blocked with his own and the pair began to duel.
You were backed into a corner and Dooku was about to start bashing you when he was suddenly stopped. Then he was flung away and you looked to the door, "Father?" you asked "hello my son, how about we take these fakes together?" he replied with a smirk "any day," you said as Valkorion activated his yellow lightsaber. You both lunged at Dooku and in moments his head was on the floor, separated from the rest of his body.
You both turned to Sidious who looked at you in horror. "So, Vitiate lives," he snarled "Master Yoda!" you exclaimed as he was flung across the room, being knocked unconscious in the process, "it takes more than a few jedi to kill me, and now, you will die like the disgrace you are," Valkorion replied and went to attack but you stopped him "no, this is my fight," you said. You got into the starting pose for Vaapad, surprising Sidious, before jumping at him with your usual force scream. You disorientated him for a moment before swinging down on him, but he blocked it and moved to the side. He then kicked you in the face and you stumbled for a split second before being forced to deflect his jab, you pulled Yoda's lightsaber to you with the force as he activated his second. You swung both lightsabers with ferocity but Sidious dodged and you blocked his attack. "We both know you'll never be as much as your father," he taunted "that may be so, but since when should I care? you're the one hiding like the coward you are," you replied which angered him and he tried to stab you through the chest. Although you had ducked and kicked him over you. You then let out a powerful force push, shoving him through the wall. However when you looked he was gone. You looked into the force and saw he was too far gone for you to catch up.
You knelt down to Yoda as he woke up. "You alright?" you asked holding out his lightsaber "well I am, thank you," he replied before noticing Vitiate "Darth Vitiate," Yoda said as you helped him up "Master Yoda, I have heard many great things about you," Valkorion replied with a small smile. You turned to your father "why are you here?" you asked "I sensed you were in trouble, and I'd like to meet this new apprentice of yours," he said as you hugged him. You then looked at Dooku's corpse, "what do we do with him?" you asked "bury him we will, deserve that much he does," Yoda replied.
