The Gallonigher system in the Colony Wars universe is a fertile system, rich in the resources needed for Humanity and the Earth Empire to continue it's expansion among the stars. But, although being valuable to the Empire, the system is a hotbed of anti-Empire activity, as it is the birthplace of the League of Free Worlds. The system's star is Evanstar.
- Bennay - Little is known about this planet, but is most well known as the sight of a major league victory over the planet for the League against the Empire in the early stages of the First Colony War.
- Acheron - Possibly the capital planet of the system, Acheron is one of the unique planets in the universe, as the planet is covered in large phosphorus lakes, which the League hid them using large 'anti-reflectors' due to fears amongst the League of a Navy invasion.
