Many stars in the Galactic Core are vast giants, full of fire and power. Few of these stars serve Humanity's needs, for they are too luminous to tolerate, and destroy all that orbit them. The smaller suns usually offer more value, and perhaps none more so than humble Govirex, an orange-yellow dwarf star about ten percent smaller than Sol. Imperial Magi have firmly established Govirex as an anomaly, a star that should by all rights have been one of the titans. It is near a thick nebula full of gas reserves, which would have offered the infant sun ample fuel to grow. 

Unfortunately, Volhak Seinal's progenitor star got there first. That long-dead sun aged, swelled into a red supergiant and died in a cataclysmic supernova. Though the shockwave likely triggered Govirex's formation, it also disrupted the primordial nebula and blew away much of the gas into long, looping streamers like smoke on the wind. And so Govirex came to be. But not all of that ancient nebula attained escape velocity. 

Falling back towards Govirex, the gaseous strands entwined upon themselves, gravitationally collapsing just as their parent star had. Granted too much angular momentum by Volhak Seinal Prime, they could not fall into Govirex but instead entered orbit. After some millions of years, Govirex became the parent of a bountiful solar system filled with gas giants. Originally there were perhaps fifteen worlds, but orbital eccentricities and collisions condensed the crowded system down to a more stable six. 

Hydrogen and Helium, being light gases, were driven farthest and fastest by the ancient supernova and hurled out of the system almost entirely. Heavier gases like water, oxygen, nitrogen, and carbon dioxide remained closer to home. Accordingly, Govirex I, II, III, IV, V, and VI are all classified as ice giants, rich in useful elements. There are no equivalents to Jupiter or Saturn here, but rather they are analogous to Uranus and Neptune, even further enriched in heavy elements. Govirex VI is even considered a brown dwarf, or "failed star". It is by far the largest, weighing in at just shy of 75 times Jupiter's mass. Thanks to Govirex VI's enormous mass, Govirex Prime has a gravitational counterweight that keeps its planetary orbits stable in the congested Core environment. 

All six planets are relatively warm, still filled with much of their birth heat. Their atmospheres roil and churn, regularly bringing vast plumes of fresh vapor from the deep interior. From these planet-sized rivers of moisture, the Atalantos Worlds drink deeply. Every year, thousands of atmospheric trawlers siphon gigatons of moisture from the Govirex System, conveying it to barren planets across the Ultima Segmentum. Without this lifeline, habitation would be impossible on many worlds. 

Inside the ice giants themselves, countless floating hab-bubbles drift through the sky, harvesting heavier gases for transport. Billions of Imperial citizens call these wandering cities home, navigating through powerful storms and lighting bolts that could wrap around Holy Terra five times over. Mundane materials are simply collected for local use, but more exotic compounds get compressed and shipped onward. Many of the hab-bubbles are dedicated to hydroponics, and feed a multitude of worlds. 

Even in the most unlikely places, the Imperium finds usable resources. Where there is water and sunlight, there is life.
