A secret battle force crusade named Angelus Mortiferus Pinnatus has been dispatched to seek and hunt down the fallen. The 4 Main Houses of the Dark Angels have come together by the sacred will of the Emperor commanded by a section of the Angels of Absolution. They were chosen to lead this Holy Crusade to purge the Imperium of Chaos and all heritical activity. Along with the special strike force command group of Absolution there arose a section from the Angels of Redemption, Angels of Vengeance and a large contingent of the mighty founders The Dark Angel's. The endeavor of hunting down the fallen necessitates a good scouting group that can operate will beyond the main force at various times. Three top sections of the RavenWing, along with its multi-potent leader Grand Master Corvus and Interragator Chaplain Leviticus, were forged to accomplish this task. Only the best and stout hearted were chosen to act as trailblazers for the main battle force. Time is short and the day of chaos is at hand. These few men are the best at scouting and guerilla tactics; recruited from the appropriate worlds that produced and molded these fine warriors so long ago.
