On the eve of battle, certain among the brethren of the Blood Angels will succumb to living visions of the death of their primarch Sanguinius. The Battle Brothers so afflicted will be gathered by the Chaplains into the Death Company, a force of blood-maddened warriors who will battle ferociously, heedless of injury, until death claims them. The Chapter's High Chaplain Astorath the Grim is drawn to the greatest concentrations of Battle-Brothers struck by this waking nightmare, meaning that an entire company has entirely given over to the Black Rage.
