Warhammer 40k - Grey Knights Short Story - Witness by Joe Parrino

On the war-wracked world of Margentum, Captain Danel Prestoff and the Brindelweld Ninth Imperial Guard stand against traitors, heretics and… something else. Something alien. Something other. As events spiral out of control, Prestoff and his men find themselves on the brink of destruction. When reinforcements arrive, it seems that all is saved. But will the new arrivals, mysterious, silver-armoured giants, bring the Brindelweld victory… or damnation?
