Centauri Prime
From Multiversal Omnipedia
Centauri Prime was the homeworld of the Centauri people and the center of the Centauri Republic. The planet was once inhabited by two races, the Xon and the Centauri themselves, who warred until every Xon was wiped out. Centauri Prime was devastated by the Interstellar Alliance and the Drakh when the latter race occupied the planet after the Shadow War.
