The Milac civilization was a technologically advanced civilization which explored the galaxy hundreds of thousands of years ago. The only confirmed Milac ruins were found on the planet Unity, and some scientists believe they were responsible for the creation of local parts of the Bozzy Spine though this matter is still heavily debated among scientists.

Though the exact fate of the Milac civilization is unknown, it no longer exists and all that is left are ancient ruins and the occasional artifact.
