13th Black Crusade - Diamor Campaign: The Blood Angels often hurl themselves into the Imperium's greatest and most terrible wars, fighting with a dynamism and determination that leaves even their brother Space Marines in awe. Of late, they have found themselves stretched thinner than ever, fighting simultaneously in the Third War for Armageddon, in actions around the Eye of Terror, and against the onrushing horror of Hive Fleet Leviathan. It was on the Shield Worlds of Cryptus that Commander Dante and many of his finest Battle-Brothers faced the horrors of the Cryptoid Tendril. This splinter fleet of Hive Fleet Leviathan was headed straight for the Blood Angels' homeworld of Baal, and its advance had to be stopped. The Blood Angels prevailed against their xenos foes, yet Baal was still at risk. Dante's forces made all speed through the Warp to return and bolster the defences of the Blood Angels Chapter planet, but they were still many solar weeks distant when word reached them from High Chaplain Astorath the Grim.A new threat had emerged in the Diamor System, an invasion by the armies of Chaos that could undermine the defences of the Cadian Gate if it were allowed to succeed. Already the High Chaplain was en route at the head of the Blood Angels' 5th Company, but greater strength would be required to defeat the traitorous foe. With a heavy heart, Commander Dante diverted much of his own force, knowing that every warrior sent away was another who could not defend Baal. Yet they were the Blood Angels. They could do no less. Dante pressed on towards Baal with little more than an Honour Guard at his side, while the rest of his warriors turned their voidcraft and made for the Diamor System.The tides of the Warp proved fickle. The warships of the Blood Angels' 1st and 2nd Companies made up considerable time on Astorath and his 5th Company warriors, and translated into the Diamor System within only solar minutes of their brothers. It was almost as though some other agency wished to see them burst simultaneously into realspace. The momentary delay proved crucial, for it was all that stood between First Captain Karlaen's forces and sudden damnation. As the First Captain established contact with the 5th Company's vessels, Death Company Chaplain Daenor informed him of their plight. As the Blood Angels' vessels translated in-system, they were suddenly enveloped by a severe psychic attack. It was Warp sorcery of some kind that engulfed the Blood Angels' voidships like a storm, but worse were its effects upon the minds of all on board. The storm inflicted visions of the sort every Blood Angel had hoped never to see. The malefic sorcery struck at the Chapter's genetic curse -- it unleashed the Black Rage. Though exact numbers remained uncertain, it appeared that almost the entirety of the 5th Company had been affected.There was a moment's pause as Karlaen digested this terrible news. The Black Rage. All Blood Angels dreaded its touch, but to have it forced upon them by some artifice of the foe...it was a violation of the highest order. Lord Astorath and Death Company Chaplain Daenor, the other Chaplains on board and their Librarians, all those with psyker training or psychic defences had survived. The rest had fallen to the curse. The mortal helots who made up the warships' crews had cloistered themselves in terror, with some having been slain by the affected Battle-Brothers. It was sheer bedlam aboard the vessels of the 5th Company. First Captain Karlaen immediately despatched the Chaplains of both the 1st and 2nd Companies, as well as the Sanguinary Guard to aid the beleaguered survivors and bring their fallen under control in an attempt to restore their ships to order.
