"Ezra Bridger: Ezra's strength in the Force continues to grow, but so does his recklessness. After the confrontation with Darth Vader on Malachor, Ezra secretly worries if he is strong enough to defeat the dark side. Now 17 years old, he becomes more daring as the rebel missions become more dangerous. He is rising in status in the Rebellion, and gaining more responsibility. Grand Admiral Thrawn: A methodical, tactical genius, Grand Admiral Thrawn is summoned by Governor Pryce to bring an end to the growing rebel threat. Thrawn is coldly analytical and values information above everything else. The only officer in the Imperial fleet of Chiss descent, Thrawn earned his position through decisive victories where he used his brilliant mind to outmaneuver his enemies. Darth Maul: Now freed from the dark depths of Malachor, Maul is running amuck in the galaxy. Driven by a decades-long thirst for vengeance that risks clouding his sanity, the restless former Sith Lord hopes to heal old wounds by completing a task he should have done years ago. Though Maul has found the galaxy has changed much during his exile, the dark side trickster knows where a few secrets are buried."

Having established a secret base on Atollon, the Ghost crew, now led by a more powerful Ezra, strengthens the rebel fleet by acquiring new resources and recruits eager to stand against the Empire. However, the Imperial efforts to eliminate the rebellion are now being led by the coldly analytical Grand Admiral Thrawn, whose strategic, tactical and cultural insights make him a threat unlike any they have faced before. In season three, Ezra and Sabine take on new roles and challenges as the rebels prepare for their biggest mission yet - a direct assault on the Empire.
