There is a legend secretly told by a few and suspicious people, a story about otherworldly forces loyal to the Emperor. About the army, woven from flame and thirst for revenge, about the brotherhood of warriors, which, although it seems to be space paratroopers, turns out to be a hundred times more deadly than any Astartes. These warriors appear when hope dies, as if coming from the afterlife to bring retribution to the Emperor's enemies. Having fulfilled their bloody duty, they disappear, again becoming part of the legend.
