Dark Angel (DLC)

The Dark Angels are considered among the most powerful and secretive of the Loyalist Space Marine Chapters and were the first of the original 20 Space Marine Legions to be created during the First Founding. Though they claim complete allegiance and service to the Emperor of Mankind, their actions and secret goals at times seem at odds with that professed loyalty, as the Dark Angels strive above all other things to atone for an ancient crime committed over 10,000 standard years ago against the trust of the Emperor during the time of the Great Crusade and the Horus Heresy.

With their Primarch missing and their Battle-Brothers on Caliban having betrayed them to Chaos, the Dark Angels swore to redeem themselves in the eyes of the Emperor and force the Fallen Angels to repent or die. To this day, the Dark Angels and their Successor Chapters call themselves the Unforgiven, and wage a war of repentance to wipe this secret stain from the honour of the Chapter. They can never truly rest until every one of the Fallen has been eliminated, and Dark Angels hold the duty of capturing or killing the Fallen as their most important duty, superseding all other necessities. There have been cases where the Dark Angels have literally left the battlefield in the middle of combat against the Emperor's foes in order to chase down a suspected sighting of a Fallen Angel.
