The Civago (Common: [sɪˈvɛɡo̞]) are a widely differentiated species of arthropods. They were introduced to interstellar civilization nearly a thousand years ago by the Kimmigan during the Foremarch, and by the time the Alganna Eternity formed, they were already civilizational partners of said Kimmigan. Today, most of them live in the various Great Houses, but over the centuries many have also left the Eternity for various reasons.
