“Even a father can learn from his children. The restless fortitude of Jaghatai. The cunning of Alpharius. The confidence of Roboute. The dauntless heart of Mortarion, afraid of nothing, not even death. The way that Russ trained anger to be utterly loyal, while Angron enslaved anger so it could not master him. The patient resolve of Rogal, willing to make, abandon, and remake his plans, again and again, over and over, until he has refined the one that will work, unafraid to redraft and change his scheme.”
