If you’re curious: the gloubari are not particularly more or less advanced than humanity is, technology-wise, so this wasn’t an imposed colony. They instead acquired the Saturn colony in a complicated land estate deal that ended with humanity picking up three rather nice terrestrial-type planets in gloubari systems in exchange. This means that both sides in “Just Don’t Look Over The Edge” are firmly convinced that they’ve robbed each other blind, which is always good for interstellar amity.
