The Angels of Purity were once fanatically loyal to the Imperium and merciless to it's enemies. But, like all other Blood Angel Successors, it was only a matter of time before they fell under the curse of the Black Rage . After centuries of locking up battle brother after battle brother, the Angels of Purity believed themselves to be cursed by the Imperium, that they were in fact the evil of the universe and not, as they were told, the Great Enemy . They were eventually excommunicated by the Imperium after they launched an attack on a Balck Templar Fleet, destroying several of their vessels in the process. They are noted by Loyalist Chapters as savage and fanatical in their beliefs, and an unrelenting force that needs to be purged from the galaxy.
