The year is 2679. 160 years ago humanity was evicted from their home, invaded by the terrifying Scourge. A parasitic race determined to capture or kill every living being, they overwhelmed mankind’s defences.
Humanity escaped to the Colonies, abandoning Earth and the Cradle Worlds to their attackers. Now the United Colonies of Mankind have come back, fighting a bitter war for their home known as the Reconquest. They are beset on all sides not just from the Scourge, but the ancient alien Shaltari, the abandonists of the Post-Human Republic, and even on occupied worlds by the embittered Resistance.
