Official description Edit

The battle to save the galaxy reaches new heights of peril and new depths of darkness. The valiant Jedi Knights and clone troopers defend exotic planets from enemy forces. They wage war underwater, battle across a night-shrouded world and take on the merciless Death Watch. Our heroes are tested like never before as Anakin is haunted by the realities of his past, Ahsoka fights to free her people, and an undercover Obi-Wan braves a deadly bounty hunter tournament. Season Four culminates with the shocking return of a villain from the past: the ruthless Darth Maul, who will stop at nothing to achieve vengeance.
