Proxima System

The Proxima System was the star system closest to the Sol System.

Components

 * The primary star of the Proxima System was Proxima Centauri.
 * The system contained a city called New Old Detroit, on a planet most likely of the same name.
 * The system also contained an asteroid upon which Stormlight House was situated. (DWM: Mortal Beloved/The Deep Hereafter)
 * If Proxima Centauri is anything like its real world counterpart, the star and any orbiting object would also orbit the binary pair Alpha Centauri A and B.
