Prolog:
The year, 2089, mankind has reached the stars, but there is trouble on the horizon. Their solar system was beginning to over populate, so half of its population had launched themselves on colony ships. Into space they went and were never heard from again, till now. In the year 2099 about 10 years later after the loss of half of the Earth's population the "Earth Federation" government was created. Soon the earth federation had started construction of shipyards and colonies in space, orbiting the solar system's planets, and some on the inhabitable planets in the sol system. The shipyards started constructing trade ships, colony ships, science ships, convoy ships, and war ships for the earth federation's trade, defense, and patrol forces.
Soon though space in the solar system was growing smaller, so the earth federation launched a science ship escorted by a small patrol force out of the sol system to find new planets to maybe inhabit or more free areas of space to build space colonies. The ships did not return for two months, which was already 6 weeks past their due date to return with a report on what was out there. Soon though a badly bruised and damaged patrol ship, return to the sol system. Only half of the crew was alive on the ship, and the ship's captain was dead. The crew kept telling Earth's president that unknown ships attacked them.
They said that after being 8 weeks out of the sol system they came by a planet, but the planet was inhabited by humans, the same people who had left earth 10 years ago when the planet was over crowded (of course they didn't know it was their own people yet) They said that there were 8 ships orbiting the planet that fired upon them, when they came into sensor range to confirm their hypothesis. All of the patrol ships were destroyed except for theirs and the science ship, because they were able to escape the attacking vessels, but unfortunately the science ship was to badly damage and its hyper engine was already destroyed. So it was running on full thruster instead and soon enough the engine was starting to over load. The patrol ship had to dock with the science vessel in order to get the scientists off safely, but it took to long to get all the scientists off. By the time the ship was about to hyper jump the 8 enemy ships had caught up with them and attacked them.
They were barely able to get back alive and the cost was half of their crew 6 scientists and their captain; but before the captain died he told his commander, "get our people home, get them home", and then he died on the sickbay bed. After they told earth's president the president made an announcement to all the sol system's ships and colonies. He said to be careful and to not leave the sol system until they can learn more about the ships that attacked the patrol and its science ship. Mostly though, they wanted to know, if the ships and that planet were actually inhabited by the people of Earth. This announcement had crushed a lot of the members of the Earth Federation spirits about exploring the outer area of the sol system. Especially one ensign by the name of Sora who was being assigned to a patrol ship. He did not know that this event would grow into a war with "The Earth Federation" and the soon to be discovered later on as "The Rebel Confederation". But later on, their will be a new enemy, one that will bring humanity to the brink of extinction, on both sides. And no it's not the Covenant.
