Andromeda Galaxy
The Andromeda Galaxy (M31, or NGC 224) is the closest spiral galaxy to the Milky Way Galaxy, located approximately 2,500,000 light years from the Alpha Quadrant at its closest point.
An ancient humanoid race from the Andromeda Galaxy became extinct following the destruction of their homeworld when their sun went supernova. Remnants of the species survived for a time on scattered outposts but eventually died out, leaving their android populations on their own. One of these android-populated outposts was the planet Mudd in the Milky Way Galaxy.
Centuries ago, Kelvans became aware of dangerously rising radiation levels in Andromeda, a development expected to make that galaxy uninhabitable for their species within 10,000 years. The Kelvan Empire has dispatched expeditions of multi-generational starships to explore the neighboring galaxies for territories suitable for conquest and occupation.
Hypothetically, a Constitution-class starship running at maximum warp would take thousands of years to complete the journey to Andromeda.
