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. On Earth, the defensive forces fight to keep the hearts and minds of their fellow humans, but Peepo’s plans are slowly converting the people to her way of thinking, and the Mercenary Guild troops continue to root out the forces arrayed against them.

War has come to the worlds of Humans. The rich planet of Tau-Rietzke, however, is far from Earth and the Mercenary Guild’s invasion, and its alien-registered mercenary companies are a safe haven for humans on the run. Organizations like the Midnight Sun Free Company. Having just completed another successful mission and taken possession of three Raknars, it was party time for Saisho Branco and the Midnight Sun personnel, and they were enjoying a little down time...until the war spilled over into their corner of the galaxy and two competing organizations showed up to steal the Raknars.

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.

Abraham Murdock left his home of Sheridan, Arkansas, at 17 to start a merc career that spanned almost 50 years, working for dozens of companies, killing aliens and getting paid across the galaxy. Near the end of his career, he landed a gig with Cartwright’s Cavaliers. The storied Four Horsemen unit was just coming back from near catastrophe, and the battle-proven Murdock was an ideal choice for their top sergeant. It would have been a perfect last contract, but then his dropship was destroyed in the Chimsa system, killing the flight crew and him. Or did it?

Bjorn Tovesson III, the owner of Bjorn’s Berserkers, is a man tied to the past but who’s not afraid to innovate. Whether it is new tactics or new equipment, Bjorn is willing to try anything once, in an effort to grow his company into the status of the fabled Four Horsemen. Looking to the future with his eyes open, though, he has seen a series of unfortunate occurrences running through the ranks of Earth’s mercenaries. Companies in financial troubles, some taking huge losses on contracts...and others not returning from their contracts at all. 

When Todd’s critically damaged ship dropped out of hyperspace near the human colony world of Azure, he had no memory of his past. He didn’t know who he was, or even what he was, and the humans didn’t either. That didn’t stop the colonists of Azure - they took him in, anyway...even though they didn’t understand how he could do some of the things he could do. Todd and his descendants consider themselves human - eight-armed and water-breathing - but human, nonetheless. After 70 years living among humans, Todd’s descendants are going back out into the Union to make their mark.

Peacemakers. The Galactic Union’s most capable enforcers and resolute negotiators, their name alone elicits fear and awe among the Union’s citizenry. When necessary, the Peacemaker Guild deputizes citizens to carry out special missions of great difficulty and danger. The only person ever to land a Combat Assault System, Personal (CASPer) from high-altitude free fall without a parachute, Tara Mason’s career as a mercenary showed promise, but it crumbled under poor choices and even worse leadership

For Colonel Mulbah Luo and the Kakata Korps, their initial contracts with the Mercenary Guild had them defending Earth. Honest work, they were led to believe, keeping the citizens of Earth safe from alien pacification in their own way. As the occupation continues, however, their eyes are opened to the fact that the hand gripping their throat is slowly tightening.

With Alexis Cromwell shot in the back by her XO and the fleet in ruins, the Humans have run back to New Warsaw to lick their wounds, but the Merc Guild now knows the location of their hidden base, and they are in hot pursuit. Led by the New Era, a dreadnought built for the sole purpose of destroying humanity, they are an unstoppable force.

The plot by the Galactic Union’s Mercenary Guild against the Four Horsemen has culminated in an invasion of Earth. Faced with an overwhelming force, the human mercs had no choice. They’ve fled, leaving Sansar Enkh to go to the Mercenary Guild headquarters on Capital Planet to stand trial for humanity. On the run, Jim Cartwright and Nigel Shirazi have travelled to the Winged Hussars’ secret base of New Warsaw, in an effort to convince Alexis Cromwell to join the fight, while the other mercenaries who escaped the fall of Earth have gone to the perceived safe haven of Karma.
