Though the Dark Angels' name is spoken across the Imperium, very few know the tale of their origins. The truth is that they once teetered on the very brink of heresy, that a terrible betrayal besmirched all of the Chapter's feats of valour and left an indelible stain on their honour. From that time, they have striven for absolution. Only the highest ranking members of the Dark Angels know the terrible secret that drives their Chapter to search through space and time for the traitors who betrayed the Emperor.

The shadowy history of the Dark Angels is explored in Codex: Dark Angels. It also contains the complete Dark Angels army list and profiles of the Dark Angels' greatest leaders. Click here to learn more about the Dark Angels.
