Dawn of Fire: Warhammer 40,000

A great darkness has befallen the galaxy, and the armies of Chaos are rampant. To survive, humanity must retaliate and take back what they have lost. By the will of the reborn primarch, Roboute Guilliman, is the Indomitus Crusade launched - a military undertaking that eclipses all others in known history. From the Throneworld of Terra does the Avenging Son hurl his fleets, their mission the very salvation of mankind.

As the Indomitus Crusade begins, fleets of mighty warships leave Terra on a vital quest to stabilise Imperium Sanctus in the wake of the Great Rift. The returned primarch, Roboute Guilliman, leads a huge force towards the shrine world of Gathalamor, where stable warp routes will allow the flotilla to spread across the beleaguered southern half of the Imperium.

The Indomitus Crusade has brought the Emperor's vengeance to thousands of star systems. The fleets and armies under the leadership of Roboute Guilliman fight for the survival of humanity against the forces of the Chaos Gods. But the traitors and heretics are not the only foe looking to destroy the rule of Terra. Xenos prey on human worlds in numbers not seen for millennia. Worst amongst them are the rampaging orks, whose migration conquests threaten to reverse the many gains of Fleet Primus.

The Indomitus Crusade continues its war across the stars. The primarch Roboute Guilliman has finally broken through the orkish threat bedevilling the sectors near Fenris, and makes ready to push on his bid to stabilise the Imperium Sanctus—but old and bitter foes stand in his way. Kor Phaeron, the Dark Cardinal, threatens the previously stable core of the Segmentum Solar. Waves of rebellion instigated by his infiltrating priests suggest an imminent, large-scale invasion by the Word Bearers Legion. 

A war-weary Battle Group Praxis arrives at the Knight world of Kamidar, ruled by the Iron Queen Orlah, to return the queen's slain daughter and heir, who died in Guilliman's name. In truth, the Imperium's mission here is twofold: to strip Kamidar of its resources in order to resupply the flagging armada, and to prepare the Ironhold Protectorate to become part of the defensive Anaxian Line, a crucial bulwark for the Indomitus Crusade.

The Indomitus Crusade burns across the stars, while new threats emerge to challenge the Imperium's resurgence. As the Kingdom of Iron is secured and the Primarch Reborn's thoughts turn to future salients, the Arch-enemy strikes back against the Indomitus Crusade's forces. The shrine worlds of the Golden Chain are all but broken, and only Velua remains defiant. Canoness Irinya of the Order of Our Martyred Lady and Champion Gaheris of the Black Templars hold the line, fighting against the plague-ridden cultists reducing the planet to anarchy.

The mighty fleets of the Indomitus Crusade face terrors and dangers beyond imagining. As Guilliman's crusade marches forth, bringing the Emperor's light to thousands of worlds, Fleet Secundus is headed for the darkest dark – the Eye of Terror itself. Along with warriors of the Adepta Sororitas and the Adeptus Astartes, the Imperial Navy battle cruiser Judgement of the Void pushes deeper into contested space. But as their journey unfolds, the forces of Chaos close in, and a battle for survival is about to begin.
