Star destroyers fly through the void of space pushing towards Kashyyyk an imperial landing craft goes between them and heads towards the ground where you can already hear blaster fire and tie fighters flying through the jungle-like trees, The craft opens with steam pouring from the top of the exit ramp, a person slowly emerges from the steam Kurrrrr hawwww Kuuurrrrr hawwwww! The breathing goes on endlessly, after a minute the person is interrupted by an officer who said "Lord Vader, we were ambushed upon our arrival but I have the situation well in – hnnn" the officer was interrupted and started floating, while Vader's hand was hovering in the air in front of him with a mechanical voice he said "I have no interest in your feelings im here on a mission of my own" the officer falls to the ground and catches his breath as Darth Vader continues forth through the houses of Kashyyyk.
he came across a few storm troopers and Wookiees, any Wookie he came across would drop to the ground burnt, some cut in half, he had a few Wookie warriors who were gutsy enough to basically jump into his blade, they fall to the ground dead.
as he continue on he could see a noble looking house nearby that was connected Via bridges as Vader came to the first bridge a tie fighter crashed into it, Vader span and continued onwards going a different way, which led through a different bridge which seemed to Lead to another bridge that lead him to the noble house, he fought waves of Wookiees but they were no match for him, each fell as easily as the next, as he got closer to the house he felt someone powerful in the way of the force.
He approaches the open field only to have a jedi waiting at the doorstep of the noble house which turns out to be what looks like a jedi temple, the jedi ran at Darth Vader who was ready for it, this was not the jedi that he sensed, but Darth Vader fought with great fury, blocking every attack that was placed, he swung the rogue jedi around into trees and rocks, as the rogue jedi grew weaker and weaker.
after half an hour of dueling this jedi, Vader managed to weaken him a lot, enough to move him without retaliation, Darth Vader threw the Rogue Jedi To the door of the temple when the jedi stood up Vader had already powered up his force push and let it loose pushing the rogue Jedi into the temple, Vader walked through the door and lifted the rogue jedi in the air readying his lightsaber, "I sense someone a lot more powerful then you, Where is your master" the rogue jedi struggled to speak but said "The dark side has clouded your mind, you killed my master years ago." As Vader raised his saber ready to strike he said, "then you will share his fate…" just then His lightsaber left his hand and headed towards a child, with a small bit of shock in his voice Vader said, "A son" The rogue jedi yelled to the child "run!" then his neck snapped and he fell to the floor a lifeless body.

Vader approaches the child While Vader approached the child the child moved back slightly, Darth Vader reached out his hand then a small squad of troopers lead by one officer ran in "Lord Vader" they look at the child who raises the lightsaber facing it towards them, the officer approached Vader's Side and signalled the three troops that were with him to open fire.
As they did so Vader grabbed his lightsaber, and protected the scared child, they left as soon as they could.

(Galen Marek's Journal entry)

I've had years of intense training, many different simulated training programs given by my training bot Proxy, Also many hard duels with Darth Vader.
Proxy has posed as many different Jedi of old; Obi-wan Kenobi, Anakin Skywalker, Qui-Gon Gin, Rahm Kota, Darth maul and many More, Each simulation was different, But each one was won by me.
Every day was a challenge to survive, but I have passed the trials, what awaits me after im accepted?
(End of Galen Marek's Journal Entry)

Years after training its time, i approach Darth Vader who says "Starkiller…When I found you, you were weak, Your hatred and anger have made you stronger, our spies have located a jedi…Rahm Kota go to him, kill him and come back with his saber." Starkiller Responded "Yes, my master" then he went off to his ship, on the way there obi-wan jumps down and starts attacking him, he easily parried each strike then executed a final attack which changed him to a grey and black Bot with a triangular core glowing an orange-red.
"Proxy, really?" Starkiller asked, Proxy responded "im sorry master, I thought if I used an earlier module then I would throw you off then finally fulfill my primary programming" They continued forward, when the rogue shadow got in eyesight starkiller saw a pilot, pulling Proxy to the side he asked, "who's that?" Proxy Changed to a lady wearing imperial officer clothes and responded, "Captain Juno Eclipse, born on Corulag where she became the youngest student ever accepted into the Imperial Academy." Proxy removes the hologram projection of Juno reverting back to his basic look.

When they leave the area where they are standing she was waiting just around the corner, they are surprised to see her so close near them, she informs them she improved the Rogue shadow to have a better sensor array, She then says "My orders are clear; I'm to keep your ship running and fly you wherever your missions require." They went into the rogue Shadow.

*five minutes after boarding the ship*

Starkiller turns to proxy "Proxy, Give me the Target" in Response Proxy changed to a rugged looking man who has a scar just below his right eye, his armour looks like iron, his robe is a crimson red, his pants are cream with a greyish-black Drape hanging in front of it.

"Rahm Kota, A rebel Tactician he served as a jedi in the clone wars, when order 66 was executed he disappeared and would prefer to use his own trained militia as they are more reliable, he has only just been found by our spies."

They head to Nar Shadaar.
