The Sagittarius dwarf Spheroidal galaxy (Sag Sph for short) is the closest galaxy to the Milky Way, and is governed by Commonwealth, the Shev'ra, the Confederacy of Borealis and a few Class I civ's. The Confederacy governs around 15% of the galaxy, the Shev'ra govern about 75% and the Xa'Thins, govern about 2% of the galaxy, the rest being left to Class 1 Civs.
In 1994 CE, the Sag dSph galaxy was discovered by Humanity. It was claimed to officially be the closest galaxy to the Milky Way.It was seen very clearly by advanced telescopes. In 5391, the FUSS colonized the first of their planets within the galaxy. Sag dSph is currently heading to collide with the Milky Way, though not much will happen.
In 5483 CE, the Shevins, a mid type 2 civilization was discovered and are now very close allies of Humanity.
