In the movie, a young Ahsoka Tano arrives, saying she was sent by Master Yoda to serve as Anakin’s Padawan. She aides Anakin, Obi-Wan Kenobi, Rex, Cody, and the clone army as they battle for the Republic on Christophsis.
Altogether, it’s a collection of shorts that center on female characters from Star Wars. We see Ahsoka team up with Padmé to subdue an assassin, and she also teaches Padmé to pilot a jet fighter in a different episode.
Fans were left wondering what happened to Ahsoka after she left the Jedi Order towards the end of The Clone Wars. The novel by E.K. Johnston takes place after The Clone Wars and before Ahsoka re-appears in Star Wars Rebels.
The series centers on a ragtag group aboard the starship Ghost as they fight against the Empire. After Organa learns of Ahsoka Tano’s rebel activity during the Ahsoka novel, he recruited her into his movement.
Previous to this, she had set out on a journey to look for a Jedi named Ezra, who had been pulled into hyperspace with Grand Admiral Thrawn. When we see her again on The Mandalorian, we learn that she is still searching for Ezra.
Ahsoka’s appearance on The Mandalorian leads up to her own spin-off series, Ahsoka. It takes place five or so years after Star Wars: Episode VI – The Return of the Jedi, the same as The Mandalorian and The Book of Boba Fett.
