At least you're not alone in your daily chores. Fleshy, unintelligent and very unattractive human creatures live on these planets. You've discovered they're quite amenable to being told what to do, even if those tasks are as limited as carrying resources back and forth. Mix some DNA from a few different species, however, and you can breed humans with special powers. Like, say... laser beam eyes! A little mod here, a little hack there and they might turn out to be quite useful!
