It has taken four years of fighting, four years of research and invention at Prometheus - with a lot of help - and four years of building the Alliance of Planets into a force that can take on the rapacious expansion of the Navscar cells from the Core.

Extraordinary individuals have helped the Alliance every step of the way. The Shellport leadership that finally crushed the power of the Descendants of the Prophet, Fedic Vits' life-threatening missions, and the personal journeys of Celia, Manoba, and Asura as they strive to keep the Alliance fighting back.

Now, finally, the big questions can be answered. Why was humanity transplanted to Earth 200 thousand years ago? What caused the Caerbrindii to split into three constantly warring races countless millennia ago? And how can the Alliance destroy the alien city in the Antares sun, and force the Navscar back to the Core?
