A homesteader ship was a specific class of starship. In a Force vision of the future, the Eye of Webbish Bog revealed to the Sith Lord Darth Vader, sometime between 3 ABY and 4 ABY, that a group of homesteaders journeyed to Kligson's Moon using one of these homesteader ships. Following their arrival, they encountered Ajax Sigma, a droid who had also come to the moon in search of a needed item for him. Sigma claimed the homesteaders attacked him, leading him to kill them all, creating a disturbance in the Force that was sensed by the Jedi Luke Skywalker.
Skywalker, accompanied by Leia Organa, Lando Calrissian, Chewbacca, C-3PO, and R2-D2, subsequently traveled to the moon to investigate the source of this disturbance. Upon reaching the moon, Skywalker guided the rebels to the homesteader ship, where they discovered the deceased crew members. The Jedi then suggested they divide into pairs to search the ship, suspecting the killer might still be present. Skywalker partnered with R2, and as they explored the ship, they encountered Sigma. Skywalker questioned the droid about his reasons for killing the homesteaders. After hearing Sigma's explanation, Skywalker ignited his lightsaber and informed Sigma that he would be taken to answer for his actions against the ship's crew. Sigma resisted, attacking Skywalker. After Skywalker damaged Sigma's plating, he demanded the droid surrender or face destruction. The droid then remarked to Skywalker about the lack of consideration for alternatives by humans, before escaping the ship in a pod.
