Nym was a Feeorin pirate captain who led the Lok Revenants. Known for his theft and subsequent use of a Scurrg H-6 prototype bomber, the Havoc, Nym’s depredations eventually earned him the ire of the Trade Federation, who hired mercenary Vana Sage to capture and imprison him. However, Nym escaped from his imprisonment, only to find that Sage, who had been double-crossed by the Trade Federation herself, wished to ally with him to inflict further damage on the Trade Federation. Furthermore, the starfighter pilot Rhys Dallows, whose homeworld had been invaded by the Trade Federation, and the Toydarian smuggler Reti joined with them as well. Together, the four launched a number of raids on Trade Federation property, culminating on attacks on the Trade Federation blockade of Naboo and the destruction of a Trade Federation droid production facility on Eos. Those actions earned Nym a pardon from the Republic, though he continued his life of piracy.

Shortly before the outbreak of the Clone Wars, Nym’s forces came under attack by the Trade Federation once again, this time in the Karthakk system. With the aid of Reti, his wingman Jinkins, and Jedi Master Adi Gallia, Nym was able to destroy several illegal Trade Federation facilities, including a weapons plant producing a biological weapon known as trihexalon. During this time, he ran afoul of a Separatist-aligned mercenary named Cavik Toth, who was behind the trihexalon production. Undaunted, Nym continued to battle Toth’s Sabaoth Squadron as well as the Trade Federation, to the point where he was able to seize back his base on Lok, which had been overrun by the Trade Federation years before. Once he did so, the Feeorin ran his operation from there, into the Galactic Civil War, in which he targeted Imperial holdings and was seen as a Rebel sympathizer.
