Adventure Military Space Opera

For a decade, peace has reigned in interstellar space. A tripartite agreement between the Colonial Union, the Earth, and the alien Conclave has kept the forces of war at bay, even when some would have preferred to return to the fighting and struggle of former times. For now, more sensible heads have prevailed – and have even championed unity. But now, there is a new force that threatens the hard-maintained peace: The Consu, the most advanced intelligent species humans have ever met, are on the cusp of a species-defining civil war.

The Warmaster’s horde advances through the fire and ash of Terra's dying breaths, forcing the loyalists back to the Delphic Battlement—the very walls of the Sanctum Imperialis. Angron, Primarch of the World Eaters and Herald of Horus, has achieved immortality through annihilation—now he leads the armies of the damned in a wrathful tide, destroying all before them as the warp begins its poisonous corruption of Terra's very soil.

On the 13th day of Secundus, the bombardment of Terra began. With the solar defences overcome through the devastating strength of the Traitor armada and the power of the warp, Horus launches his assault on the Throneworld in earnest. After withstanding a ferocious barrage of ordnance, an immense ground war commences outside the Palace, with every inch gained paid for in the lives of billions.

The galaxy was once terrorized by the Sturm, a group of “species purists” intent on destroying any human with genetic or cybernetic enhancements. Fashioning themselves as the one true “Human Republic,” the Sturm cut a bloody swath across the stars, killing billions before finally being defeated and driven into the far reaches of Dark Space. Centuries of peace bred complacency. Everyone believed the Sturm had died out in the Dark. They were wrong.

Major Jimjoy Earle Wright, secret agent of the Empire, is intelligent and highly trained. But he succeeds all too well in overthrowing a military dictatorship - and the result is a new government inimical to the Empire and disgrace for Jimjoy. After surviving two assassination attempts, Jimjoy realizes that it's his own imperial superiors who want him dead; that, in fact, his worst enemies could become his best friends. He fights his way to safety on the planet Accord, where the Ecolitan Institute wins his loyalty and changes his identity.

The galaxy remembers Hadrian Marlowe as a hero: the man who burned every last alien Cielcin from the sky. They remember him as a monster: the devil who destroyed a sun, casually annihilating four billion human lives - even the emperor himself - against Imperial orders. But Hadrian was not a hero. He was not a monster. He was not even a soldier. Fleeing his father and a future as a torturer, Hadrian finds himself stranded on a strange, backwater world.

The 200 years' (and counting) peace was a time of tranquility that hasn't been seen since...well, ever. Mankind in the Galactic Age had finally conquered war, so what was left for the military to do but drink and barbecue? That's the kind of military that Sergeant R. Wilson Rogers lived in before he left the fleet to become a smuggler. But it turns out that smuggling is hard. Like getting-arrested-for-dealing-with-pirates-and-forced-back-into-service kind of hard.

The last reward Kira Demirci expected for heroism in a time of war was to spend the rest of her life dodging assassins - but when her government betrays her as part of their surrender, she and her comrades flee the star system of Apollo to the edge of civilized space.

With an entire squadron supposed to follow in her wake, it falls to her to build a new home for her comrades.

The lines. No ship can traverse the void without them. Only linesmen can work with them. But only Ean Lambert hears their song. And everyone thinks he's crazy....

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.
