In between the rise of The Galactic Empire and the outbreak of The Galactic Civil War, Darth Vader was dispatched to Kashyyyk to defeat a Wookie uprising led by a Jedi survivor of Order 66 named Kento Marek, but once he struck down the Jedi Knight and his wife, Mallie Marek, Vader found out they had a son named Galen and takes the boy under his wing, giving him the codename "Starkiller".
Over the timeline of 18 BBY - 2 BBY, Vader trains Starkiller to one day overthrow his Master, Darth Sidious, and rule the galaxy the way he sees fit. However, Starkiller is then betrayed by his Master and forced to find his own path as a Jedi in the future Rebel Alliance...
