The mechanics of the Invaders resided at the rear of the repair hangar of the Mjølner base. They were relocated there from the residential area for technical personnel because it was deemed necessary for them to be on constant standby to ensure the smooth functioning of the entire expansionist system. The former warehouse of exploitative materials was adapted into living quarters so that technicians could respond more quickly to any malfunctions in interstellar units. The service personnel had their own canteen (with more than terrible food), a dingy social room (which practically no one used, as there was no perceived need for affiliation), a row of foul-smelling toilets, one functional shower, and a bit more freedom, which was more precious to them than any possible comforts. Thanks to this change in accommodation, the mechanics were closer to the repair hangar, with only one checkpoint along the way, and daily checks were usually swift and cursory to avoid delaying repairs. Unfortunately, the mandatory breaks were damn inconvenient for them, especially during wartime campaigns when the number of malfunctions became much greater than usual. The mechanics, gathered in in a tight isolation chamber had to wait idly until the incoming Invader was checked and cleansed. During this time, the enforcer guards (commonly referred to as "cleaners") ensured that no alien life forms attempted to infiltrate the base, hidden somewhere in the hull of each incoming Invader. It was jokingly called "dealienization." Only after completing all necessary procedures, carried out by enforcers clad in protective suits, could the service personnel return to their work.
