Battered and broken, Sarkis and the Federation of Outer Planets emerged from the battle from Eire, victorious.

However, it quickly becomes clear that they have won the battle, not the war. They know that before long, the Undying Legion will return. No matter how many human lives are sacrificed across the millions of miles of trench lines across the galaxy, the Legion will never break a sweat, will never rest, and will never stay dead. Sarkis, Noa, and their allies come to the conclusion the only way to end the war once and for all is the strike at the heart of the Techno King's Empire: PRIME CITY.
