Galen Marek was a Human male taken as a secret apprentice by Darth Vader from his father, a Jedi, named Kento Marek on Kashyyyk during the Great Jedi Purge. For years, the Dark Lord trained him, under the codename Starkiller, in dark side arts and to eliminate his enemies, including Jedi who survived Order 66. In 3 BBY, he fell in love with Juno Eclipse, and spent time together when they were on missions. He was the father of Anakin Marek, who was given the name of Galen's former master, after finding out about Vader's true identity.
