The story centers on the fate of the warship Lord Solar Macharius, its captain and crew during the era of battles for the Gothic sector of the Imperium. Converging in battle with the hordes of Chaos, “Macharius” wins brilliant victories, but the battles become more and more fierce, the enemies are stronger and more insidious, for the commander of the hordes of Chaos is none other than Abaddon, the heir of Horus.

Entire worlds and star systems fight and die in this colossal battle. Victories and defeats follow each other like day and night. And now the Defiler has an absolute weapon in his hands - the “Planet Killer”.

And the hour of execution is approaching...
