Darth Vader's secret apprentice known as Galen Marek, or in other words codenamed Starkiller, is trained in the Dark Side to defeat the enemies of the Empire but must find his own path when his master betrays him. Later on, a couple of days, months or years afterward, a clone of Starkiller is created by Darth Vader, but, after he escapes his master's grasp, he travels across the galaxy to discover who, or what, he really is.
