Bug swarms, space slugs, brains on legs, mad Imperial scientists—Zak has had enough! He's glad to be on board the luxury space yacht, Star of Empire, where at last, there's peace and quiet. Until—"Abandon ship! Critical meltdown!" As a blaring siren sounds, panic-stricken passengers rush to get off the ship. Everyone evacuates…except Zak and Tash. But to their relief, nothing happens. There's no meltdown, no explosion. Everything is fine. Except that the ship's exits are sealed and all communications have been shut down. Zak and Tash are trapped. And they are not alone.

A group of different alien races have been taken prisoner and brought to the Negation universe. A number of the prisoners had innate incredible powers while many, like Obregon Kaine however, were merely ordinary humans. Nevertheless, his wisdom and tactical military experience made him the perfect person to lead the prisoners.
