Aelfin Imperium

Centuries ago, with the push of the unknown Precursor civilization, the Aelfin people took to the stars, colonizing and terraforming, believing the universe was created for them to claim. However, they soon stumbled upon another race of people on another planet, then another, then another. They soon realized the universe was teeming with life, and the universe was not theirs to claim, but to conquer.
