Als der Kriegsherr Horus sich gegen den Imperator auflehnte, zerstörte der darauf folgende Bürgerkrieg beinahe das Imperium. Space Marines kämpften gegen ihre eigenen Brüder in einer Auseinandersetzung, aus der nur der Tod als Sieger hervorging. Doch die Legionen rangen schon lange vor diesem Zeitpunkt mit ihrer eigenen Identität und den Anforderungen des Großen Kreuzzugs, mit dem der Imperator die Galaxis für die Menschheit erobern wollte.

In surviving the horrors onboard the Eisenstein, Nathaniel Garro proved his courage and absolute loyalty to the Emperor. On his return to Terra, Garro is despatched on a mission of even greater importance - a mission given to him by Malcador the Sigillite himself.

Once again Garro must fight for survival, but now he also fights to achieve a higher purpose....

From out of the shadows of the Silent War, a hero emerges. Clad all in grey, an errant warrior of the Legiones Astartes kneels before the Regent of Terra, and accepts a solemn new duty - Battle-Captain Garro, once commander of the Eisenstein, now Agentia Primus of Malcador the Sigillite. From the desolation of Isstvan to the halls of the Imperial Palace itself, he stands as a paragon of loyalty and protector of the innocent, ever ready to strike back at the traitorous allies of the Warmaster.

Daher ist die Kontrolle über diese Welt im kommenden Krieg von entscheidender Bedeutung. Die Agenten des Kriegsherrn beginnen die Glut der Rebellion zu schüren und die loyalen Schmieden und mächtigen Titanenlegionen gegeneinander aufzuhetzen.
