Biography[]
Birth on Kashyyyk[]
Galen Marek was a force sensitive born on Kashyyyk after the foundation of the Galactic Empire. His mother was killed by a pack of bandits when he was an infant.
Meeting Darth Vader[]
Sometime after his birth around 15 BBY, Kashyyyk was invaded by the Galactic Empire, led by Darth Vader, who was after Galen's father. After a heated battle, Galen's father was killed after Vader force choked him, crushing his throat. Galen watched in horror as his father's limp body fell to the floor, and a squad of Stormtroopers came in and aimed at him. However, Vader killed all the troopers and instructed Galen to come with him, to which the young child accepted. This would begin his journey as a Sith Assassin, and eventually a Sith Lord.
Mission to Kill General Kota[]
After 15 years of intense and merciless training from Darth Vader, away from the prying eyes of the Empire and Sidious himself, Galen Marek, now codenamed 'Starkiller', was knighted as a Sith Apprentice and sent on his first mission to kill Jedi Purge survivor, Rahm Kota. Starkiller met his new pilot, Juno Eclipse, and set off on the mission in his ship, the Rogue Shadow.
After locating Kota, Starkiller entered a space station where Kota was located, to find a huge battle between Kota's Militia and the Empire in progress. Starkiller proceeded through the ship, killing Stormtroopers and Militia Members alike, before finally reaching Kota. The two engaged in a vicious brawl, which escalated as Kota ripped the bridge off the ship, sending it plummeting down to Naa Shadda's orbit. However, Starkiller got the upper hand after he cut out Kota's eyes, blinding him and sending him plummeting out of the ship. Starkiller then grabbed Kota's lightsaber and jumped down to the Rogue Shadow, and headed back to Vader.
