The Lok Revenants, also known as the Lok Resistance, were a group of pirates operating out of Lok in the Karthakk system prior, during and after the Clone Wars. The Revenants were led by the piratecaptainNym.
The Lok Revenants were loyal to Nym, and aided the pirate captain on many raids against the Trade Federation. They defended Nym's base on Lok from a large invasion force, and though eventually overwhelmed, the Revenants regrouped and continued the fight. The Federation was struck a big blow at the Invasion of Naboo, but still remained a sizable presence in the Karthakk system. For the next ten years, the Revenants waged war with the Federation.
It was not until Jedi MasterAdi Gallia intervened that the tide began to turn. By now, the Revenants were joined by Sol Sixxa and the Mere Resistance, and launched an assault against the heavily-defended factory world of Nod Kartha. They later participated in the battle over Geonosis, helping to defeat Captain Cavik Toth and his Hex fleet. Ultimately, Nym's forces recovered their base on Lok, and Nym remained in contact with Master Gallia.
With the establishment of Galactic Empire the Revenants chose to hide from its watchful eye on their home base at Lok, where no other organization has any influence. Most of the Revenants had some grudge against the Empire, and most of the group members wanted a chance to get back at the Empire any way they could. The Revenants preferred to hit primarily Imperial convoys and cargo vessels that came too close to their base, although other prey was not unheard of. Though the Revenants targeted Imperial vessels and sold supplies and weapons to the Rebel Alliance and other anti-Imperial organizations, they still considered themselves to remain neutral in the Galactic Civil War.
