Moon Base
A Moon Base was established by the Ur-Quan Kzer-Za Hierarchy after the subjugation of Earth. Due to the central role the Humans had played in the Alliance of Free Stars, as well as their planet's abundance in natural resources and industrial capacity and the Humans' demonstrated aptitude for tenacity and cunning, the Ur-Quan opted to leave a larger-than-usual garrison to keep watch over the enslaved Humans. They left a force consisting of the two neighboring battle thrall races, the Spathi and the Ilwrath, to form an "Earthguard" garrison on Luna, Earth's moon.
Unfortunately, when the Kzer-Za disappeared to fight the Doctrinal Conflict, discipline broke down, and the Ilwrath, the leading forces of the Earthguard, soon left to join in the hunting of the Pkunk that had been dictated by Dogar and Kazon. Their remaining Spathi subordinates soon let their paranoia get the better of them, slowly migrating their base from Luna to Mars to Ganymede and so on, hoping to put distance between themselves and the humans so as to minimize the chance of having to fight an escaped rebel human force without backup. In order to prevent their human charges from learning about their cowardice, they carefully rigged an automated system to make the Luna base continue to appear active, constantly running the base's life-support systems, programming construction robots to move dirt and rocks around, and constantly broadcasting "Winky's Happy Night", a Melnorme FunRom, over transmission channels to simulate radio chatter.
The ruse was successful, keeping the few Humans on the Starbase intensely worried about the Earthguard until The Captain finally came along in The Flagship, proposing an alliance to resume resistance against the Kzer-Za. Intrigued but fearing the potential consequences of failure, the Starbase's Commander Hayes asked The Captain to prove the power of his Precursor technology and his own prowess as a commander by removing the imminent Earthguard threat. The Captain sent a team that duly investigated the Luna base and found it abandoned, scrapping and salvaging most of its useful equipment and returning to The Flagship. Discovering there was no immediate threat from the Hierarchy, Hayes' mind was slightly put at ease, but he only put his full confidence in The Captain and agreed to support his New Alliance of Free Stars after The Captain later proved his worth in real combat by engaging and destroying a weakened Ilwrath Avenger that came to check on the Starbase.
By most accounts, Luna was the first world to be liberated from Hierarchy rule.
