Horizon Base was an Imperial outpost that was both a shipping port and fueling station. The Ghost crew, in need of fuel, pulled off a daring heist at Horizon Base; the rebel astromech, Chopper, accidentally left there, eventually stole an Imperial cargo ship from the site. In the process, he recruited the inventory droid AP-5 to join the cause of the rebellion.
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.
Chopper was the resident droid of the Ghost, assisting the crew in everything from ship maintenance to combat -- even though he didn't always want to. After many years of repairs and patch jobs, Chopper had a beat-up, worn look that matched his sometimes cranky personality. Aesthetics aside, he was an essential part of this small rebel team, and ultimately, was loyal and heroic.
Stormtroopers are elite shock troops fanatically loyal to the Empire and impossible to sway from the Imperial cause. They wear imposing white armor, which offers a wide range of survival equipment and temperature controls to allow the soldiers to survive in almost any environment. Stormtroopers wield blaster rifles and pistols with great skill, and attack in hordes to overwhelm their enemies. Along with standard stormtroopers, the Empire has organized several specialized units, including snowtroopers and scout troopers.
An Arquitens-class light cruiser, the Imperial light cruiser was a double threat, both powerful and fast. It was equipped with multiple quad laser turrets and double-barreled turbolaser batteries, as well as concussion missile launchers, while quicker and more maneuverable than a Star Destroyer. After the destruction of the Lothal communications tower, a light cruiser was used to capture and relay information from surface courier droids brought aboard.
