For everyone that likes Warhammer 40k Tabletop and Dawn of War Games or anything to do with Warhammer 40K.
"Because we cannot be trusted. The Emperor needs a weapon that will never obey its own desires before the good of others. Most of all, he needs a weapon that will never bite the hand that feeds. We are not that weapon. We've all drawn blades purely for the sake of shedding blood, and we've all felt the exultation of winning a war that never even needed to happen. We are not the tame, reliable pets that the Emperor needs. The Wolves obey, when we might not. The Wolves can be trusted, when we couldn't. They have a discipline we lack, because their passions are not aflame with Butcher's Nails buzzing in the back of their skulls.
The Wolves will always come to heel when called. In that regard, it is a mystery why they name themselves wolves. They are tame, collared by the Emperor, obeying his every whim. But a wolf doesn't behave that way. Only a dog does.
The moment we realized that truth, we changed out Legion's name. That is why we are the Eaters of Worlds, and the War Hounds no longer."
