Military Space Opera

The Custodian Guard have stood watch over the Emperor's Palace on Terra since the foundation of the Imperium. Charged with protecting the Master of Mankind from all threats, within and without, their fearsome resolve is renowned throughout the galaxy, and their golden armour is the last thing that a would-be assassin or saboteur will ever see.

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 Merry Band of Pirates are in desperate trouble after the end of their last mission, and the real danger to humanity is just getting started. Hostile aliens have discovered there is something odd going on with wormholes in the galaxy, and their investigations could lead to finding a shortcut to Earth....

The Traitor Host of Horus Lupercal tightens its iron grip on the Palace of Terra, and one by one the walls and bastions begin to crumple and collapse. Rogal Dorn, Praetorian of Terra, redoubles his efforts to keep the relentless enemy at bay, but his forces are vastly outnumbered and hopelessly outgunned. Dorn simply cannot defend everything. Any chance of survival now requires sacrifice, but what battles dare he lose so that others can be won? Is there one tactical stroke, one crucial combat, that could turn the tide forever and win the war outright?

The elite crew of the pirate ship UNS Flying Dutchman had a simple mission: determining whether the Thuranin are sending another starship to Earth. Along the way, they became sidetracked by securing a future for the UNEF troops on the planet Paradise. When asked whether Earth was now safe, their ancient alien AI responded "Not so much"...now they have to deal with the consequences.

The Interdependency, humanity’s interstellar empire, is on the verge of collapse. The Flow, the extra-dimensional conduit that makes travel between the stars possible, is disappearing, leaving entire star systems stranded. When it goes, human civilization may go with it - unless desperate measures can be taken. Emperox Grayland II, the leader of the Interdependency, is ready to take those measures to help ensure the survival of billions. But nothing is ever that easy.

The war for the fate of mankind blazes on. Though the outer defences have fallen, the walls of the Palace itself remain inviolate as Rogal Dorn, the Praetorian of Terra himself, uses every known stratagem and ploy to keep Horus' vast armies at bay. In Perturabo, the Traitor siegebreaker, Dorn faces an adversary worthy of his skill. A terrible, grinding attrition ensues. The crucial battle for the Lion's Gate spaceport is at the heart of this conflict. With it in their possession, the Traitors can land their most devastating weapons on Terran soil. Dorn knows it must not fall.

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.

The isolated forge world of Diamantus faces a threat of apocalyptic proportions – a warped and mutated space hulk infested by the forces of Chaos, commanded by the monstrous datagnost Voldire, disciple of the dread demigod Vashtorr the Arkifane. As the battle-weary Carcharodons make their stand alongside the Adeptus Mechanicus, horrors and nightmares raining down around them, the Space Marines must confront their place within this new Imperium, and destroy the hulk before Diamantus is lost.

A cease-fire that has lasted seven years... Worlds half-destroyed that have been rebuilt anew... Friends and crewmates scattered light-years apart... New leaders that would be kings... The Jung threat has been renewed, in ways not imagined. It will take a new savior to inspire the masses, and once again lead those willing to fight against oppression. But who will the new savior be?

After a series of victories, the Imperial forces are on the back foot once more. The power of Chaos is rising, the Traitors gain ground, and all hope seems lost. Can Terra endure?

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.

After seven years of bitter war, the end has come at last for the conflict known infamously as the Horus Heresy. Terra now lies within the Warmaster’s sights, the Throneworld and the seat of his father’s rule. Horus’ desire is nothing less than the death of the Emperor of Mankind and the utter subjugation of the Imperium. He has become the ascendant vessel of Chaos and amassed a terrible army with which to enact his will and vengeance. But the way to the Throne will be hard as the primarch Rogal Dorn, the Praetorian and protector of Terra, marshals the defences.

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.
