From the nightmare of the past comes a deadly threat to the future. Far out in uncharted space the Imperial battleship, ISS Leviathan, the last of her monstrous kind, has been repaired by her fanatical crew and is ready to launch. Her commander, Lord Hargo, knows that the war-weakened Federation has nothing now that can defeat her and he intends to use her power to destroy the Federation and restore the Empire; with himself as Emperor. Only Adam Stark and Ariel Helsen oppose him and if they can't find a way to stop him, The Federation is doomed.
