The Columbus System orbits a G-type main sequence star known as Columbus Sol. It consists of five planets, one dense asteroid belt, and multiple natural satellites. The system is notable for its varied terrain, stable orbital zones, and strategic deep-space features.
Planetary Order (from innermost to outermost):
1.    Celtrix: A volcanic world rich in rare earth minerals. High tectonic instability. Surface is quarantined due to extreme crustal volatility.
2.    Karros:     A mildly terraformed Earth-like planet. Stable atmosphere and moderate climate. Contains prebuilt colony shells and domed infrastructure.
3.    The Dravax Belt: A dense asteroid belt containing rich mineral deposits. Frequent debris fields and echo interference.
4.    Cindar Major: A large gas giant with 12 moons. 
5.    Cindar Minor: A smaller gas giant with extreme atmospheric storms.
6.    Sereos: An icy dwarf planet on a highly inclined orbit. Very thin atmosphere. Considered suitable for outer-system monitoring stations.
