Ahsoka is paving the way for some huge events in the Star Wars galaxy. Episode 6, "Far, Far Away," reintroduces Lars Mikkelsen's Grand Admiral Thrawn, last seen on Star Wars Rebels, and moves the action to an entirely new galaxy. Upon arriving in the new galaxy, the villainous crew of the Eye of Sion approaches the planet Peridea, which is soon revealed to be the original homeworld of the Dathomiri -- ancestors to the Nightsisters of Dathomir. The return of Grand Admiral Thrawn after his disappearance at the end of Rebels and the revelations surrounding the Nightsisters' origins come with major implications for the Star Wars galaxy's past and future.
