Kile existed as a satellite of the gas giant Zhar, which itself was located within the Zhar system. This moon became the location of a base established by Rogue Squadron; it served as their staging point for planning the mission aimed at liberating Han Solo from the clutches of Boba Fett and his ship, the Slave I. In contrast, Gall, the other moon orbiting Zhar, was a terrestrial planet with a population and an Imperial presence.
