"For eleven hundred years I have fought, and I have seen the darkness in our galaxy. I have seen the vileness of the alien and the heresy of the mutant. I have seen all the evil that the galaxy harbors, and I have slain all whoes presence defiles the Emperor. I have seen what you will see. I have fought what you must fight, and I have slain what you must slay..." - Commander Dante of the Blood Angels chapter (Warhammer 40,000)
