The “image” Filoni was referring to appears in a scene from “Attack of the Clones” where Obi-Wan Kenobi goes to the Jedi Archives looking for the Kamino system — the only clue he has as to the origin of the bounty hunter who tried to kill Padmé earlier in the film. Upon realizing that the Kamino system is missing from the archives, he asks Master Jocasta Nu for assistance and shows her a map of the known galaxy. In the map, we see the main galaxy housing the Republic, but there are also two satellite galaxies to the sides.
For Filoni, the introduction of a whole other galaxy far, far away is more than just a plot convenience. “You know me, I plan for a long game. I really do,” the filmmaker told Vanity Fair. “And that encompasses a lot more than it used to, as I help other people as well.” This refers to Filoni’s newly-announced role within Lucasfilm as chief creative officer.
As for the future of “Star Wars” in the aftermath of “Ahsoka,” Filoni had the following to say:
“I’m setting up what seems to be a larger conflict with the Imperial remnant. That conflict can’t just mirror what we’ve seen before. It has to take on a different shape. It can’t just be the Empire versus what looks like the Rebellion, or even the Republic. It has to be visually different.”
