Peacemakers. The Galactic Union’s most capable enforcers and resolute negotiators, their name alone elicits fear and awe among the Union’s citizenry. It is a time of upheaval throughout the Galactic Union. As the effects of the Omega War ripple outward, a Peacemaker falls silent at the outpost mining colony of Parmick. Sensing danger, the Peacemaker Guild dispatches two new graduates of the Academy to investigate and report. They are a new breed of Peacemaker, perfect for the clandestine infiltration mission.

The Peacemaker-enforced ceasefire brought an end to the hostilities, but not a resolution, and now it’s up to the Four Horsemen to forge a lasting peace.

Before Hr'ent Golramm became a legendary Enforcer for the Peacemaker Guild, he was a mere candidate. Granted, he was a particularly unusual candidate - only six Oogar had ever successfully graduated from the Peacemaker Academy on Ocono, and Hr'ent would be the seventh. Every candidate must pass a commissioning mission in order to graduate, though, and Hr'ent's is unsolvable. The Pushtal of Vorrhurna were once one of the Mercenary Guild's 37 races.

On the African savanna, the male lion is the lord who watches over his family, while the females of the clan do the real work. Joel “The Lyon” Lyons thought that owning a mercenary company would be similar—he could sit back and allow the Lyoness to run the Pride. Everything would go well, money from successfully completed contracts would flow like water into his bank accounts, and everything would be as easy as it had been for him when he’d owned a chain of highly successful restaurants.

At a time when Humans were just starting to venture forth into the Galactic Union as mercenaries, Martin Quincy survived long enough to do something no one else had - he retired. There was only one problem: He got bored. After battling aliens for many years - killing aliens and getting paid - retirement didn’t suit him, and he decided to strap on the combat armor and go back to the stars. Along with his old friend Kal, Martin joined Cartwright’s Cavaliers, humanity’s best merc company. Life was exciting! But he got bored. Again.

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

Convicted of a minor traffic violation, Rev Pelletier is conscripted into the Perseus Union Marine Corps...for up to a 30-year term of service.

Get ready to experience two more origin stories in the Backyard Starship universe.

We were fighting on the wrong side of a war we couldn't win. And that was the good news. The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the native Americans in 1492. Over the horizon come ships of a technologically advanced, aggressive culture, and BAM! There go the good old days, when humans only got killed by each other. So, Columbus Day. It fits. When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved.

Worse still, a dying alien chieftain gives them a priceless drive of intel, marking them for death. The mission has officially changed. With enemies on all sides, Magnus must do everything in his power to protect the emissary and escape the tower.

Leaving behind a warring Earth flung headfirst into a conflict of mutual assured destruction, the Rangers and the accompanying crew of first colonists are guided on a 40-year journey by an unprecedented artificial intelligence. But when they emerge from the frigid embrace of cryosleep, they awake to a nightmare, finding themselves greeted by the same ruthless enemy that brought about the ruin of Earth.
