An army of droids was brought together by Ajax Sigma, a droid insurgent, as he strived to liberate droids throughout the galaxy. This army perpetrated the Kligson's Moon Uprising, an event that resulted in the complete annihilation of all life on Kligson's Moon. In the end, this army fought the Jedi Order on the moon in the High Republic Era, a conflict that saw Sigma defeated by the Jedi Loden Greatstorm.
