The Galactic Confederation was an organization composed of allied species existing prior to the formation of the Interstellar Union, yet they oppose them in an attempt for galactic domination. The Galactic Confederation is an older and more experience union, and is believed to be composed widely of Tier 2 species, such as the Lhimp. Most of them haven't been encountered by Humans, as their territory is greatly spread out across much of the Sagittarius and Scutum-Crux Arms.
