From the introduction:
Welcome to a galaxy far, far away. A galaxy under the tyrannical boot of the GALACTIC EMPIRE and its forces of darkness, in this time period with no hope for rebellion. All of the Empire’s opponents lie dead or in hiding with the Jedi as the fires of the Clone Wars have come to an end and the Jedi are hiding from Darth Vader, the Emperor’s Fist, who hunts them down throughout the galaxy. On one of these hunts during a rebellion on Kashyyyk the Dark Lord comes across young Galen Marek, the child of two Jedi, containing the potential to help Vader overthrow his master. You start three years before the Battle of Yavin, which is one year before Darth Vader will send Galen Marek on his fateful mission to assassinate General Rahm Kota, a Jedi Master, in order to prepare him to aid in the overthrow of Emperor Palpatine.
