The Double War was a centuries-long conflict between the Federal Empire and two alien races, the Fyndii and the Hrangans. It was also known as the Great War, the Fyndiin War, the Hrangan Conflict, the Thousand-Years War, or simply as the War. In many ways the Double War was in reality two conflicts; the enemies never had any contact with each other and were in no sense allies, though both were engaged in warfare against humanity.

The Federal Empire occupied the space between the two enemies, and thus fought on two fronts; the Fyndii hordes were inward toward the Core, the so-called Hrangan Empire outward toward the galactic fringe. The war against the Fyndii began first, and was generally a shorter and cleaner conflict, finally resolved through negotiations and the intervention of a third alien race, the Damoosh. The Hrangans were considerably less understandable and much more inimicable to humanity. Hostilities never officially ended between Hranga and Earth; both civilisations collapsed. Humanity underwent the Interregnum and recovered, although never again as a single political unit. The Hrangans suffered virtual genocide at the hands of their own slaveraces and human colonials.[1]
