Those unable to attend Star Wars Celebration in London missed out on the chance to see Star Wars Rebels Season 3 early, but at last, we have a end date for our despair. Star Wars Rebels Season 3 sets an official September premiere, along with a new synopsis teasing the arrival of Grand Admiral Thrawn.

Per the official announcement, Star Wars Rebels will return for Season 3 premiere “Step Into Shadow” on Saturday, September 24 at 8:30 P.M. Eastern and Pacific. For an early taste, here’s the official synopsis:

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.

Well, one that’s surely doomed to fail, but someone’s got to keep those Y-Wings warm! In the meantime, check out the latest Star Wars Rebels Season 3 trailer below, and stay tuned for more on the September 24 premiere.
