The Death Company is a special unit unique to the Blood Angels and their Successor Chapters, consisting of former Battle-Brothers, who have succumbed to the Black Rage, a delusional state which makes them uncontrollably violent. Since the Rage is incurable, these unfortunate souls are re-formed into a new unit, to be unleashed at the opening of the next battle. Their Power Armour is repainted black, to signify their new affiliation.
The Death Company will fight regardless of the odds against them or their injuries preferring to regain some portion of their honour by dying heroically in battle. Those few who do survive battle are returned to the Chapter, to be placed in stasis awaiting their next battle.
