Twenty hours after twelve alien spacecraft appeared over Earth; Russia launched a nuclear missile at the closest ship. The missile strike did not go to plan. Not only did the ship destroy the missile within seconds of launch; all twelve ships responded with very precise strikes against over ninety percent of land-based missile silos and mobile launch platforms, completely destroying the vast majority of Earth's nuclear weapon capability.
Twenty-four hours after twelve alien spacecraft appeared over Earth; the entire combined combat capability of every country on Earth was destroyed or disabled without a single human casualty. Completely overmatched, the world's governments joined together and entered negotiations with the advanced visitors. The result of negotiation were called the Earth Accords.
Twenty years later the Earth Accords have resulted in all of humanity becoming a unified work force designed to trade natural resources for advanced technology. To enforce peace (or maybe just obedience) a very small group of humans have been equipped with extremely advanced weapon systems and work as the world's only military unit.
These humans make up the Earth Defense Force.
Not everyone is happy with the situation, and while Earth speaks in public with one governmental voice; intrigue, plots, and conspiracies blur the lines between the peace of the world and the progress of humanity.
Will the Defense Force maintain peace for all humans or work towards a greater prosperity for some of humanity?
