The slaughter is on! Across the galaxy, human mercenaries are being ambushed, and an ever-increasing number of companies aren't returning from their contracts. Someone even appears to be plotting the demise of the premier Four Horsemen companies, and disaster for the other three companies has only been averted by the narrowest of margins. Sansar Enkh, the president of The Golden Horde, knows her company is likely to be next, but has no idea who is behind the attacks, or when they will strike her beloved Horde.

For more than a century, Winged Hussars has been the richest of Earth's mercenary companies, as well as the only one to specialize in space warfare. Led by Alexis Cromwell, they have carved out a reputation in the galaxy for being dependable, unflappable, and lethally efficient. Until people began shooting at them everywhere they went.

Peacemakers. The Galactic Union's most capable enforcers and resolute negotiators, their name alone elicits fear and awe among the Union's citizenry. Having completed a harrowing confirmation mission, Jessica Francis stands ready to become Earth's first Peacemaker and believes obtaining her commission is a mere formality. However, certain members of the Guild question her ability. Worried that she'll fall back on her mercenary ways, they want Jessica to prove her mettle.

Nigel Shirazi was first in line for the chairmanship of Asbaran Solutions, one of the prominent "Four Horsemen" mercenary companies. First in line...until his drinking and temper caused him to fail out of college and get disinherited by the family. Now he leads the life of a playboy, enjoying a stipend from the family to stay out of the way. But someone is out to get his family, and Nigel is all that stands between the hidden enemy and the destruction of Asbaran Solutions and the Shirazi family.

Heir to one of the leading "Four Horsemen" mercenary companies, Jim Cartwright is having a bad year. Having failed his high school VOWS tests, he's just learned his mother bankrupted the family company before disappearing, robbing him of his Cavalier birthright. But the Horsemen of eras past were smart - they left a legacy of equipment Jim can use to complete the next contract and resurrect the company.

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.

While the occupation of Earth continues, MinSha mercenaries under the command of Major General Drehnayl have assaulted human-held colonies in the outer rim, wiping them out. With the famed Four Horsemen nowhere to be found, the Mercenary Guild’s attempt to instill fear and subvert humanity is perilously close to reality. Tasked with finding the MinSha is Jessica Francis, Earth’s first Peacemaker, but the odds aren’t in her favor. Jessica realizes that finding Drehnayl's forces isn’t enough - she must do something to stop their atrocities and end their reign of terror.

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.

Peacemakers. The Galactic Union's most capable enforcers and resolute negotiators, their name alone elicits fear and awe among the Union's citizenry. Except for Jessica Francis. Not only is she the newest Peacemaker, Jessica is also the first Human Peacemaker, and she commands the respect of few, both inside and outside the Peacemaker's Guild. No one believes humanity is ready to take on the mantle of being a Peacemaker, and Jessica is stuck flying a desk. That is, until a species-induction mission comes along, and she is in the right time and place to get assigned to it. 

CASPers - Combat Assault Systems, Personal - are the lords of the future battlefield. The massive mechs were created to give humanity an edge against the rest of the mercenary forces in the Galactic Union. Just like today's tanks, though, massive amounts of armor and weaponry just make the CASPers "hard to kill", not "invulnerable". There are things in the galaxy even stronger than the CASPer, and when humans run up against them, it's up to the human inside to figure out a way to snatch victory from the jaws of defeat.

First contact has been made, and Earth's militaries and its premier mercenary companies stand ready to take their first tentative steps outside the solar system. With a galaxy of aliens to explore and fistfuls of credits to be made, follow along as the Four Horsemen select their contracts and venture forth to meet their destinies. 

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.

The battle-scarred star carrier Flying Dutchman is finally on her way back to Earth, after an exceptionally successful series of missions that have once again saved the world. The ship needs a serious refit, and her exhausted crew just wants a break from constant clandestine warfare against a vicious and superior enemy. Wishes come true, right? Not for the Merry Band of Pirates.

After saving the world many times, the Merry Band of Pirates have accepted the inevitable: Earth is doomed. All they can do is try to bring a few thousand people to safety, before vicious aliens arrive to destroy humanity's home world. No. There is one other thing they can do: hit the enemy so hard that the aliens will regret they ever heard of humans.

The human soldiers stranded on the planet Paradise have been recruited into an alien legion to do the dirty jobs that the high-tech species won't do. Their first mission is to kick the enemy off a backwater planet no one cares about. It's a simple assignment, except everyone has a hidden agenda, and the planet could become a deathtrap.
