Military Space Opera

As the Warmaster's campaign of galactic domination continues, his generals seek out fresh battlefields to conquer. After leaving the Crone World of Iydris behind, Perturabo strikes for Tallarn. A bitter, vengeful primarch, the lord of the Iron Warriors unleashes a deadly bombardment against the world, killing millions but entrenching the survivors. A brutal, all-consuming armoured conflict ensues, the greatest of the war and one that grinds down all combatants over more than a year of relentless battles.

Terra is besieged. The outcome of the war lies on a knife edge. The Warmaster Horus’ bloody seven-year crusade has led to this – the cradle of humanity, where he is to kill his father, the Emperor. With the war at this critical juncture, Sanguinius, primarch of the loyalist Blood Angels, braves the horrors of the Warmaster’s flagship, The Vengeful Spirit, with a single purpose in mind – to slay his brother Horus, decapitate the Heresy once and for all, and stop the forces of Chaos from taking Terra.

It was supposed to be a peaceful exploration, Earth's first step in expanding to the stars. But, no plan survives first contact. Thrown into a battle for survival against the deadliest threats imaginable, the Marines must contend with ice and desert planets with mysterious creatures, along with a history of turmoil that threatens to spill over to Earth if not checked. Meanwhile, a genetically-engineered threat rises on Earth - one that holds the secret to this intergalactic war.

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?

His humanitarian mission collides with a newborn military beginning to flex its muscles - and a newborn nation prepared to accept no violations of its sovereignty, regardless of their needs.

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?
