All was peaceful - until that fateful day when the Madrons, in a stunning surprise attack, reappeared apparently from nowhere, and utterly destroyed Centrus, the teeming capital world of the Empire. Pursued by Imperial Battleships, the Madrons fled through a previously undiscovered spatial anomaly that led to a far-flung and unexplored corner of another Galaxy. With vengeance in its heart, the Empire immediately dispatched their newest, most advanced and most powerful space fleet through the anomaly to track down and destroy the Madrons once and for all.
