Lifetime of War
Chapter 3: The Human Expansion
Our long range probes discovered the Humans using Element Zero powered ships. In addition they picked up several colonies. Our greatest fears were realized: Humans had achieved inter-galactic travel. Using the Relays they populated many of the world's we deemed 'unfit' and 'too low of value.'
Not only were they populated, they were transformed into sprawling metropolis areas where filth and squalor seemed to be the rule of the land, there were worlds made for industry and agricultural.
Their way of maintaining rule was inefficient to say the least. It did create a form of dependency so one world could not rebel without multiple worlds supporting it. Were their rulers so backwards and oppressive they forced this system on their own people? Or were they that bad at governing? Either way we observed them devouring entire worlds- watching as they thrived in places not even fit for the poorest of the Terminus residents.
In time we knew they would wage an apocalyptic war against us- it was in their nature to wage war. We needed to cut off their head so we convened to form a solution. Our best SPECTER agent, Saren, would be sent to Earth as an ambassador of peace. There he would assassinate the leader of their "Republic."
