The last of the three original colonies settled by mankind thousands of years in the past has been destroyed. Britannia, America, and Melbourne have all been attacked and destroyed by two aggressive, advanced alien civilizations. But the humans on Melbourne managed to escape and settle other colonies before Melbourne was found and destroyed. Now the colonies are hiding in the outer spiral arm of the Milky Way building up their defenses against the day when they can take on their attackers. Sixteen years have passed, and New Britannia and the colonies have continued to build up their forces without being discovered by their enemies. But one day, the time would come to confront their attackers. The challenge will be difficult; their enemies still far outnumber them and the only thing keeping them safe is remaining hidden. But sometimes, events can force one out of hiding. Fighting to save Humanity is one such event.
