The Milky Way galaxy is a spiral galaxy found in the Local Group. It is diverse with a myriad of species with empires that span from only a few star systems to whole arms of the galaxy. Life is constantly evolving and the empires within continue to struggle.

Structure[edit | edit source]
The Milky Way has five arms and roughly 100 billion planets, some of which can support complex, multicellular life forms. It is approximately 100,000 light-years across and contains 200-400 billion stars. A barred spiral, it has a mass of around 700 billion solar masses, and more than double that if dark matter is included.
The Milky Way also has a Galactic Habitable Zone. Around the edge of the galaxy, the metallicity of stars drops disallowing the formation of planets. Metallicity increases the closer one is to the Galactic Core resulting in more planets, but so does radiation from the supermassive singularity at its center. In the middle, however, life can flourish.
