Horus Heresy #1: Burden of Duty & Grey Angel

As the renegade forces of the Warmaster storm across the galaxy, a very different kind of war rages in the shadows of the Imperium - the Knights Errant, chosen of Malcador himself, move quietly in the dark places where others cannot. Battle-captain Nathaniel Garro makes his way to the Imperial Fists’ mighty starfort Phalanx, seeking out another kindred soul for his elite band of warriors. Meanwhile, on distant Caliban, former Sons of Horus Garviel Loken and Iacton Qruze undertake a mission to ascertain the true loyalties of the Ist Legion.
