The member states of the Confederacy of Borealis have a combined territory of 24 galaxies. While this sounds like a truly large number, over 97% of the stars under the control of Confederate States reside in Via Sagittaria. Over three fourths of the remaining stars are in the Ouranir Galaxy and, if one includes Ventemir, only about a per mille of the stars under the Confederacy's control exist in galaxies outside of Via Sagittaria. Even so, Via Sagittaria's often take center-stage in intergalactic affairs.

Via Sagittaria is the political and economic center of the Confederacy. It is home to several major species, most notably Humans, Dotsk. and Un'oits. It is also home to the two Kardashev III civilizations within the Confederacy, the United Federation of Star Systems and Sagittarium. Via Sagittaria is home to dozens of important worlds and has been one of the most influential galaxies within the Local Universe, its influence only overshadowed by Aylothn, one of the few galaxies that also happens to overshadow it in size as well. As far as galaxies go, Via Sagittaria is vast. 400 Billion stars is an absurdly large number of stars; the average galaxy only has several million at the largest.
Given its vast size, its civilizations have only colonized a percentage of the stars the galaxy has to offer. Most stars colonized exist within one hundred light-years of what are known as "home-worlds" which are more often than not ecumenopoli carrying the majority of the galaxy's population. Within Via Sagittaria exists two Birch Planets, mega-structures constructed around black holes that can hold staggering numbers of people. These two planets are named for the black holes they were built around, Mili and Nocturne, the latter of which is the central black hole of the galaxy. These structures account for nine percent of the Confederacy's population and are by far the most important locales to the Confederacy.
