The Omega War is in full swing. Earth has fallen to General Peepo's army, and the surviving Human mercenaries have taken refuge at the hidden Winged Hussars' base in New Warsaw.

As humanity begins to think about how to recover the planet, one thing is obvious—more powerful weapons of war will be needed in the effort. One of the keys to recapturing Earth will be the Raknar of Cartwright's Cavaliers, but the power sources of many of the giant mecha have become unusable over the course of history.

More are needed, and Alistair Sinclair knows someone who may have a line on where to get them...a secret Science Guild base where they're being developed for the Mercenary Guild to power the Raknars Peepo has been collecting.

While the Four Horsemen try to hold back the Mercenary Guild forces, Alistair volunteers his Scorpions to track down and bring back the power sources the Raknar need for the assault on Earth. The Scorpions operate by guile, not overwhelming power, but will guile be enough when all the forces of the Mercenary Guild are arrayed against them?
