"They were despatched into the Outer Darkness upon that first Day of Exile, there to ravage the foes of mankind until their final atonement. Their Forgotten One gave them remit unbound, to set about the Traitor, the alien and the Renegade without mercy, and to harrow them in their places of strength. So began their long hunt. They hunt still."

— Mythos Angelica Mortis, Chapter 17, Paragraph 98, ca. M36
