Antidar Williams was a Human male who piloted Senatorial shuttles in the service of the Galactic Republic. Originally hailing from Barkhesh, Williams flew agricultural airspeeders in his youth, before departing his homeworld in the hope of finding adventure. He found employment with the Republic, but soon afterward he joined Senator Ranulph Tarkin's unsanctioned paramilitary force, which journeyed to the Qotile system to engage Iaco Stark's Stark Commercial Combine in the Stark Hyperspace War.
