From Warhammer 40k - Lexicanum
The Angelic Blade is a Strike Cruiser in the Blood Angels Chapter that took part in the Diamor Campaign where, along with the Strike Cruiser Flame of Baal, it carried the Fifth Company to battle. However, as soon as the Cruisers entered the Diamor System, they were both hit by the effects of a Chaos ritual conducted by the Black Legion Sorcerer Xorphas. Soon the majority of Blood Angels the Cruisers held were stricken by the Black Rage and were sadly inducted into the Death Company, which was then unleashed on the Black Legion's forces invading the Imperium world Amethal.
