The Separatist Alliance was formed by outlying star systems that aligned themselves against what they believed to be a corrupt Galactic Republic. Exploiting their sizable workforce, the Separatist Alliance has created a massive droid army that it frequently deploys to push back against the Galactic Republic’s control. While these battle droids are not the most proficient fighters, the vast amount of them the Separatist Alliance is able to put onto the battlefield has made them a considerable threat to the Republic.
