At the heart of the Auraxian system lies Luminaire, a G7V star. It has a system of seven planets which in turn have dozens of moons and moonlets.

The first two are the rocky and metallic planetoids of Shiva and Devi, rich in various heavy elements and silica. They are both extremely hot and inhospitable. The third planet is the most significant; Doramir is a large gas giant with two major moons: Auraxis and Tauaxis. Doramir, Tauaxis and Auraxis are habitable worlds with life, though Auraxis is the only one conducive to human life. The remaining two planets, Dosojin and Shangdi, are cold ice giants similar to Neptune, relatively small and wracked by storms.
