The Deathwing's mission takes precedence over all others, even though they may be called upon to fight a wide range of foes. Members of the Deathwing are indoctrinated into the outermost tiers of the Unforgiven's Inner Circle, and are party to the some of the terrible secrets surrounding the existence and nature of the Fallen. Some members of the Deathwing may know the identity of those they fight, while others are unaware the Fallen were once loyal Dark Angels, but all members of the Dark Angels 1st Company, and indeed the 1st Company of every Unforgiven Chapter, know that the Fallen are the vilest of Heretics and must be persecuted above all others.
