Andromeda Galaxy/Galactic Prime



The Andromeda Galaxy, which was around two million light years from the Milky Way Galaxy, was actually the galaxy of Galactic Prime, the same galaxy that was home to the Galactic Republic with it's capital on the planet Coruscant and the Jedi Order.

That means the Andromeda Galaxy was also the site of the Galactic Civil War between the Rebel Alliance and the Galactic Empire ruled by Palpatine.
