Gallius is a planetary system orbiting a yellow G-class star.  The system lies in the Gemini Constellation of the Hyades Region.

The Gallius System sits on the outer fringes of the Hyades Region. Though rarely visited due to its isolated location, the system has still grown into important mining colony. The primary planet is a large gas giant where valuable gasses are mined from deep below the atmosphere.


The base of the mining operations and home to nearly the entire population, is an enclosed city that orbits the gas giant. Gasses are extracted from the planet, processed in the orbiting city, then shipped to other systems in the region.

Gallius B
Gallius B is a large gas giant with nearly 1.5 times Jupiter's mass. The planet's upper atmosphere is composed primarily of hydrogen and helium, while rare gasses exist deep below the atmosphere. These gasses have been mined and exported for profit to other worlds.
