After the Clone Wars ended and the leaders of the Separatist Alliance were wiped out by the Empire, General Farstar retreated to the outskirts with other surviving separatists to Ostor. There they believed that they could escape the seizure of power by the Empire in order to continue to live in seclusion. A few months after the war ended and the Galactic Empire was established by Emperor Palpatine, Farstar was in command of a separatist cell that was nevertheless tracked down by the Empire. Darth Vader gave General Rohn the command of the Imperial forces to defeat the separatists in a military offensive and capture the planet. The first attack ended in disaster for the Empire, as it initiated Farstar's diversionary maneuver and successfully lured the Imperial forces into a canyon into a canyon from where the separatists launched an ambush attack and almost completely wiped out the enemy forces. Later, Darth Vader sent a second wave of attack into battle, this time receiving support from the air. This finally broke the defense and eliminated the leadership of the separatist group, consisting of Lima Starcourt, Phootla Veer and Reebo Keen.
