Built on one of Killun 71's jagged landmasses, Killun Station is an Imperial Security Bureau outpost housing sensitive data. Security is especially tight at the installation, which includes a stormtrooper presence at all entrances and walkthrough identification scanners. While rarely approached by rebels, undercover droids AP-5 and Chopper recovered secret Lothal orbital clearance codes from Killun Station.

Controller LT-319, outfitted with Lobot-tech headgear, was the lead intelligence officer aboard the Imperial listener ship near Killun Station. Ambitious and scheming, Controller LT-319 was eager to impress Grand Admiral Thrawn, and reprogrammed Chopper in an effort to discover the location of the rebel base. The plan would backfire, however, when Hera Syndulla restored her droid's original programming and reversed the feed, destroying the listener ship and Controller LT-319 in the process.

A beat-up, patched together astromech droid dating back to the Clone Wars, C1-10P — or Chopper —is a reliable droid who has served with Hera Syndulla for decades. Loyal to a fault, with a cranky personality to match his weathered finish, during the age of the Empire, Chopper served the Ghost crew in everything from ship maintenance to undercover missions and combat.

Proud and honorable, AP-5 was a droid that served as a navigator for the Republic military during the Clone Wars. Following the formation of the Empire, however, he was reassigned to inventory. While the position did not take advantage of his gifts, he performed his duties without complaint -- despite threats and disrespect from his Imperial commanders. It was only after a fateful meeting with the rebel astromech Chopper that AP-5 came to see he did not have to serve the Empire. He helped Chopper escape capture and defected to the rebels, helping find a safe haven away from Imperial forces.

An Imperial listener ship, technically known as an IGV-55 surveillance vessel, is one of the Empire's tools for surveillance, intel, and recon. Utilized by the Imperial Intelligence, these ships monitor communications and scan data, looking for signs of rebel acts and sedition.

Killun 71 is a moon displaying a green appearance from space due to an omnipresent layer of mist in its atmosphere. Killun 71's terrain consists of jagged masses that make colonization difficult, though the Imperial Security Bureau has established a base, Killun Station, on one of its rocky protrusions.
