Galen Marek, codenamed Starkiller, was a male Human apprentice of the Sith Lord Darth Vader. An extremely powerful Force-wielder who lived during the era of the Galactic Empire, Marek originated from the Wookiee home planet of Kashyyyk as the sole offspring of two Jedi Knights—Mallie and Kento Marek—who deserted the Jedi Order during the Clone Wars. Following the death of his mother, the young Marek's father was killed in battle by Darth Vader. Though only a child, Marek possessed an exceptionally strong connection to the Force that the Dark Lord of the Sith sought to exploit.
Thus, Darth Vader abducted Marek in order to train the orphan in the ways of the Sith Order. Although the Sith were limited to only two members at any given time, Vader nonetheless trained Marek as a secret apprentice during his own apprenticeship to Darth Sidious, the Sith Lord who ruled the galaxy as Emperor Palpatine. The physical and psychological trauma of Vader's unforgiving training regimen resulted in Marek's immersion within the dark side of the Force as his Master intended. With his childhood memories suppressed and his original identity forgotten, Marek only knew himself as the Dark Lord's apprentice; a Sith assassin who operated under the codename "Starkiller" and a living weapon to be deployed against the enemies of Darth Vader.
