By 280 A.T., Near-Jupiter space was controlled by the Jovian League, a federation between the colonies on Ganymede and Callisto, the mines of Io and the small outpost on Europa. Each of these colonies was a nation-state; the League itself (like the Gengineer Republic that was to later absorb it) was a loose association.

The largest and most massive planet in the Sol System, Jupiter was at that time still an undeveloped wilderness, rich in natural resources. The atmosphere of the giant planet was the source of much of the helium-3 burned in the interplanetary ships of the time.

In the 290s and 300s the Jovian League began accelerating the mining of atmosphere of Jupiter for helium-3, an important fuel for fusion reactors and drives. At first the high cost of extracting the gas from a gas giant atmosphere made Lunar 3He much more attractive. In 309, however, the Cis-Lunar Alliance imposed huge tariffs on helium-3 exports. The Belt responded by turning to the now considerably cheaper supplies from Jupiter. The influx of helium revenue and its increased importance to the Solar economy rapidly changed the backwater status of the League. Although by no means a great power, the Galilean colonies were no longer a joke.

Helium-3 was extracted by robotic factories, floating in the atmosphere suspended from hot-hydrogen balloons beneath the rolling banks of clouds. To remove the refined helium from the atmosphere of this massive giant and lift it into orbit was very energy-intensive; however the magnetic field of Jupiter was a convenient and powerful source of energy, allowing the extraction to occur at a considerable profit.

Other sources of energy in the Solar System could not yet compete. Saturn, Uranus and Neptune were at this time still too remote and undeveloped. Antimatter, although falling in price and seen, especially by the inner Solar System, as "the energy source of the future", was still very expensive to manufacture and maintain.

The most important faction of the Jovian League were the Genetekkers, an association of tweaked humans sent by GeneTEK and other megacorps to colonise the outer solar system. The major adaptations included in the Genetekker genome were tolerance of microgravity and the high levels of radiation found in the Jovian system, although even with such tolerance, the Genetekkers remained behind shielding as much as possible when near the Jovian radiation belt, and built their colonies beneath protective ice and rock. The lucrative mining operations on Io were mostly carried out by remote controlled, non-sentient robots.
