Alpha Centauri

Background
Alpha Centauri, formerly known as Alpha Centauri AB, is a binary star system roughly 4 light years from Earth, and containing four planets, two around each star. The system is home to the Quinto people, who originated from Alpha Centauri-b (the second planet orbiting the larger star). The third star in this locality, Proxima Centauri, was included in Alpha Centauri until the discovery of the Kashni Empire and their latent hostility in 2217. The Kashni Empire allegedly attempted to construct a 'Dyson-sphere' around Toliman, the smaller of the two stars, in 2224, beginning the war between them and the RSC.

Planets: A
A total of two planets orbit the larger star in Alpha Centauri, called Rigil Kentaurus. Many Earth citizens refer to the planets as -a and -b, but are known locally by the Qinto as Aratanu (meaning 'from Them') and Qinsenu (meaning 'for us'). Qinsenu, or -b, is the ancestral home of the Qinto, and the epicenter of their evolution into an intelligent species, much like Earth for Humans. Aratanu, or -a, was colonized by the Quinto in 2109, and terraformed by 2148. The name 'Aratanu,' which means 'from Them,' refers to the Qinto's pair of gods, who they believed originated from the two stars, and gifted the planet to them.

Planets: B
A total of two planets orbit the smaller star in Alpha Centauri, Toliman.
