The return of Roboute Guilliman, primarch of the Ultramarines, to the Dark Imperium was nothing less than a miracle. And more miraculous still is the instrument of his resurrection, the arcane technology of the Armour of Fate. More than mere battleplate, the Armour of Fate keeps the primarch alive, holding at bay the wound he sustained at the blade of his erstwhile brother. But Guilliman cannot remove the armour – or so he was told. Now, after years spent trapped within the Armour of Fate, he wishes to test the truth of this statement, and seeks out old allies who he hopes can give him aid.
