Contrary to humanity's expectations, neither leaving Earth nor expanding throught the Galaxy could change human nature. Exodus from the humanity's cradle, made in haste and in dramatic situation created problems that humanity is yet to solve. And that most likely will haunt it, until the unforgiving Galaxy will finally claim the lives of last human.
More than three hundred years passed since the beginning of the Long War. The most devastating and longest military conflict in history of humanity. The most terrible civil war to ever befell mankind. War on a scale never seen before, fought between two human factions, Terran Federation and Outer Colonies. Now, with humanity divided even on a genetic level, the chances of peace are slim at best. And there are also aliens, for whom human race - the greatest military power in the known part of the Milky Way - is a permanent threat. One that most of them would love to erase, no matter how.
Daughters and sons of Terra march to war. Over and over again. Until the end of the world.
