The Disney XD series will wrap up its 4th & final season, following the weary & embattled crew of the Ghost as they finally join up with the larger Rebellion that we know from the original trilogy.

The new trailer for the 4th season teases just that, as well as more Thrawn & surprise appearances from the Imperial villains of Rogue One.

Star Wars anthology film Rogue One will play a more high up part in this season, as Star Wars Rebels follows the timeline just before Rogue One takes place.

"It's always fun to make it feel like it's part of this big world," Star Wars Rebels executive producer Dave Filoni told Entertainment Weekly in an interview about the forthcoming season.

Rogue One character Saw Gerrera, whose appearance was cut short in the film, will show in the series to investigate the likelihood of an unknown super weapon being built near Geonosis, according to EW. But what of the crew of the Ghost, who we’ve followed for 3 seasons? They’re still on the road to recovery from their great battle with Thrawn, who will still act as the Big Bad of the season in spite of the Rogue One villains circling the story.

The fourth & final season of Star Wars Rebels premieres on Disney XD on October 16.
