From out of the shadows of the Silent War, a new 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, is now Agentia Primus of Malcador the Sigillite. From the desolation of Isstvan to the halls of the
Imperial Palace itself, Garro stands as a paragon of loyalty and protector of the innocent, ever ready to strike back at
the traitorous allies of the Warmaster. But he is walking a dangerous path of his own, one that may lead him to
question his place in the Imperium... and what if he, too, should falter?
