Set after the events of "The Clone Wars," Maul plots to rebuild his criminal syndicate on a planet untouched by the Empire. There, he crosses paths with a disillusioned young Jedi Padawan, who could be the apprentice he is seeking, that will aid him in his relentless pursuit for revenge.

The Inquisitor is dead. The Ghost crew has connected with other rebel cells. And a new ally named Ahsoka Tano has emerged. Despite these successes and developments, the fight against the Empire takes a deadly turn, as the evil Sith Lord Darth Vader comes to Lothal.
