Prelude
Sometimes, well before the Jazygian Empire took to space, Mankind began the colonization of the Solar System, with sub-FTL ships. They mined the inner and outer planets for resources, and terraformed a great swath of Mars and its moons.
As the richness of Earth grew, soon a unified Earth Government (EarthGov) was established. However, they excluded the Martian colonists from most of their decisions, and had the Martians pay exorbitant taxes when dealing within the inner Solar System. Then the colonists created the Martian Sphere, an exclusive trading zone, prohibiting Earth ships to mine the outer planets.
Things soon came to blows, at first with armed ore carrier and other merchant vessels, but both factions soon developed their own navies.
