Luke Skywalker was a legendary soldier and Jedi Master who helped defeat the Galactic Empire and found the New Republic, as well as the New Jedi Order. Born in 19 BBY, the son of the prolific Jedi Knight Anakin Skywalker and the late Naboo queen Padme Amidala, he was raised on Tatooine in solitude to hide from Emperor Palpatine and his father, now known as Darth Vader, Dark Lord of the Sith. In 0 BBY, Luke's life was changed. A chance purchase of two droids, R2-D2 and C-3PO, led to him meeting Han Solo, Princess Leia Organa, and receiving Jedi training from Obi-Wan Kenobi. Luke later destroyed the first Death Star and joined the Rebel Alliance.

Over the next few years, he fought in many of the most important battles of the Galactic Civil War. In 3 ABY, Luke received Jedi training from Yoda, and learned from Vader that the Dark Lord was his father. One year later, he fought in the Battle of Endor, and succeeded in turning his father back to the light. Thanks to Luke, Palpatine was killed, and the Empire was dealt a crippling blow. One year later, the New Republic was formed. Over the next decade, Luke helped keep peace throughout the galaxy as the New Republic slowly defeated small remnants of the Empire. In 11 ABY, he founded the New Jedi Order, and began teaching Force-sensitives about the ways of the Force. In 19 ABY, he married Mara Jade, a fellow Force user.

In 25 ABY, the Yuuzhan Vong War broke out. Though the New Republic was nearly crippled by the extra-galactic invaders, they were able to defeat the Yuuzhan Vong in 29 ABY, in large part due to Luke and his Jedi. During the war, Skywalker's wife gave birth to a son, who they named Ben after Luke's old master. After the close of the war, the New Republic was reshaped into the Galactic Alliance, and Luke reformed his Jedi Order, eventually taking the title of Jedi Grand Master. Following the Dark Nest Crisis, Luke began to question the Jedi's new view of the Force. In 40 ABY, the Second Galactic Civil War broke out, an event that shook the galaxy. Later that year, when his wife was killed, and his nephew Jacen Solo took control of the Galactic Alliance, Luke began to fear that Jacen had become a Sith, which proved to be true, as he claimed the title of Dark Lord of the Sith under the name Darth Caedus. With the aide of Luke, Caedus was killed by Jaina Solo, ending the war and restoring peace to the galaxy.
