During the test flight of a prototype faster-than-light craft, Lt. Commander Ky is flung into an ancient past that never existed. Rome has fallen, defeated by the mighty Carthaginian Empire, its survivors chased off the continent and onto what had been the remote province of Britannia. Hounded by the Carthaginians bent on conquering the known world, Rome is on the verge of destruction. Stranded and alone, except for a tactical AI implanted in his head, Ky has lost everything and must find a way to live in a world different than anything he's ever known.

Nine years ago, Lt. Commander Ky, a test pilot from the future, was flung back in time to a world that never existed. In this world, Carthage won the Punic Wars and Rome was all but destroyed, pushed back to a corner of the British Isles. That war is over. With Ky's help, the Romans formed a new Britannic Empire, defeated the mighty Carthaginian Empire, and set up a new paradigm in Europe.

Mars and the Moon have been colonized, piracy runs rampant in the asteroid belts, and a thriving society grows in the depths of space. Humanity prepares to embark upon its greatest journey - the colonization of Alpha Centauri. Then, everything changes. A deep space reconnaissance probe discovers a new Earth-like planet 12 light-years from Earth’s sun. The probe also finds something unusual, something unnerving. A new mission is created, a space fleet is formed, and humanity embarks on unravelling the greatest mystery of all - the origins of life itself.

The origins of human history begin to unravel as Earth learns they are not the only humans in the galaxy. The sudden discovery of humans living on multiple planets beyond their own has created more questions than it’s answered. When humanity arrived on New Eden, a hideous new alien race, the Zodarks was discovered. In the face of an existential threat to their own survival, the historical warring factions of Earth will need to unite if they want to save themselves from extinction and understand the true origins on human history.

Badly outnumbered, facing certain destruction, and cut off from supply, the Imperial Roman Ninth Legion Hispana is in a desperate position. Surrounded by the hostile Celtic army, Senior Centurion Lucious Grackus Lisidus Karus must lead his men to safety after unexpectedly finding himself thrust into command of the legion.

Kai of the Sorcerer's Tower was one of the last Mages left, barely surviving in a world contaminated with dead mana and ruled by creatures of the dark. To save his world and fulfill his master's last wish, he puts himself through a forbidden ritual, risking his soul being ripped into pieces to make his way into the past, to a golden era with abundant mana. But things go wrong. He overshoots and finds himself in an ancient time thousands of years earlier, within the body of a young lord named Arzan.

Joe Colsco boarded a flight from San Francisco to Chicago to attend a national chemistry meeting. He would never set foot on Earth again. On planet Anyar, Joe is found unconscious on a beach of a large island inhabited by humans where the level of technology is similar to Earth circa 1700. He awakes amid strangers speaking an unintelligible language and struggles to accept losing his previous life and finding a place in a society with different customs, needing a way to support himself and not knowing a single soul.

Our universe is ruled by physics, and faster-than-light travel is not possible - until the discovery of The Flow, an extradimensional field we can access at certain points in space-time that transports us to other worlds, around other stars. Humanity flows away from Earth, into space, and in time forgets our home world and creates a new empire, the Interdependency, whose ethos requires that no one human outpost can survive without the others. It's a hedge against interstellar war - and a system of control for the rulers of the empire.

A world on the precipice of the apocalypse. A secret forged in the flames of war. A chance to start over. For John Sutton, only one of those three things matters. Retired from a decade of brutal war, he wants nothing more than a quiet pastoral life while he does his best to stem the steady increase of his Doom Points before they hit 100, signaling the start of the end. He’s been given a small farm on the outskirts of the empire as a thanks for his service, but no matter how far he travels, it's impossible to escape the war's devastating effects on the world.

John Perry did two things on his 75th birthday. First he visited his wife's grave. Then he joined the army. The good news is that humanity finally made it into interstellar space. The bad news is that planets fit to live on are scarce—and alien races willing to fight us for them are common. So: we fight. To defend Earth, and to stake our own claim to planetary real estate. Far from Earth, the war has been going on for decades: brutal, bloody, unyielding. Earth itself is a backwater.
