The Terran Campaign was the name of the military operation to seize the Sol System. During the Galactic Senate Meeting of 4228 (2017 Earth years) the most powerful alien civilizations met together and discussed many different issues. One of them was the valuable Sol System, which was home to a pre-light speed technology race called "Terrans" or "Humans". After a long meeting armies were readied for war. While the official reason was that Terrans where too dangerous to last by themselves, everyone knew that the Senate needed resources. Five civilizations where sent ahead of time to secure Luna.
