Generally speaking, humans are typically considered the first extraterrestrial species that Dextroluma encountered, though it is contested whether they met humans or Lockettes first.  Unfortunately, even now, the relationship between humans and Dextroluma is still icy.  Dextroluma at an institutional level do not trust humans, while humans typically feel unfairly maligned for events they weren’t even alive during.  Still, humans are relatively welcome on Aerius - though their ships do seem to get randomly selected for searches by Galactica authorities with impressive frequency.

Humans require passports to be legally present in Aerius, and only a few hundred passports are granted each year.  They are not legally entitled to become permanent residents of Aerius - but some may be allowed the opportunity anyways if it is deemed in the best interest of a permanent resident of Aerius, or if they require medical treatments that cannot be received anywhere else in the galaxy.

Humans are a species from the real world, for more information on them, you may visit their wikipedia page.
