Sol Alliance
During the War of Sol, two blocs fought for complete control over the Sol System: the Alliance and the Coalition. The Alliance was composed of the democratic nations of the US, Western Europe, and Japan. For decades, there was nonstop fighting between the two factions without either side gaining the upper hand for long.
In 2160, the Alliance proposed and signed peace treaty between the two blocs, but as the Coalition admiral headed to Europa, one of Jupiter's moons, to sign it, he ordered a Coalition fleet to de-cloak and attack the Alliance fleet, who had stood down from battle after hearing about the treaty. Instead of ending the war peacefully, they destroyed the French and Italian Alliance fleets and took control of all the inner planets, including Earth. This surprise attack was what gave the Coalition the upper hand to start winning the war. Afterwards, the Alliance faced huge military losses. As a final act of desperation, the Alliance launched five sleeper ships, each containing throusands of colonists, to the Sirius System to begin a new civilization far from the war and strife that had befallen Earth.
Shortly after the Exodus of the Five Sleeper Ships, the Coalition arrived at Pluto, the last stronghold of the Alliance. As the two prepared for one last battle, a Nomad superweapon arrived and destroyed the Sol System and destroyed all traces of humanity. Although the Alliance lost the war, they were able to continue the human race by sending their people to Sirius. However, not even they could stop the onslaught of the Coalition and the Nomads. If only the Coalition had sought a peaceful resolution like the Alliance did, the destruction of Sol could have been avoided. Instead, their quest for power blinded them and caused the Nomads, who had been watching the human race, to judge all of humanity as unworthy to live.
