Asteroth, Daemon Prince of Slaanesh
"Long shall be your suffering! Joyous be your pain!"

Fabius Bile, Lieutenant Commander of the Emperor's Children
"Follow me, my Children, and the glory of victory shall be yours. We shall cleanse ourselves in the crimson waters of our enemy. We shall bring the ecstasy of quick release to those who stand before us. We shall give bloody praise to the Lord of Pleasure and sing his name as we dance across the fallen. Follow me, my Children, and you shall taste the undreamt joys that lie beyond the bounds of mortal sense."

"Great art so often fails to find an audience with the intellect to appreciate it. Sometimes I am filled with woe to think that no one in this blighted millennium has the wit to see the scope of my brilliance."

"The lesson is this. The only real crime for those of superlative intellect and great prowess is to allow one's self to become shackled by mediocrity. The crime is to let your grasp be less than your reach. To aim low."

Diuman Cilious, Alpha Legion Sorcerer
"What the thick-headed fools with their broken corpse of an Emperor fail to understand is that not only can they never defeat us, but they can not hide or flee or shield themselves from the triumph of Chaos. They are finite and we are unbound, undivided. They must not err, or they fall to heresy. All who fall join our cause. Every Imperial fool who dares to open his eyes is a willing recruit. They strive merely to hold back our fury and might, and it consumes them. Thus you can see Chaos is inevitable. We lurk not only beyond their grasp and at their gates; we lurk within the darkness of their souls, on the tip of their tongues, in their tortured dreams. We are them, but freed from the shackles of ignorance. We are them, grown strong… evolved. We are them, but so much more!"

Ghargatuloth, Daemon Prince of Tzeentch
"What is Chaos? Suffering, you might say. Oppression. Deceit. But could not all these things be said of your Imperium? You hunt down the talented and the strong-willed. You break them or sacrifice them. You lie to your citizens and wage war on those who dare speak out. The inquisitors you call masters assume guilt and execute millions on a whim. And why? Why do you do this? Because you know Chaos is there but you do not know how to fight it, so you crush your own citizens for fear that they might aid the Enemy. The Imperium suffers because of Chaos. No matter how hard you fight, that will never change. Chaos exists in a state of permanent victory over you - you dance to our tune, mortal one, you butcher and torture and repress one another because the gods of the warp require you to. The Imperium is founded on Chaos. My lord Tzeentch won your war a long, long time ago."

Grimspyre, Daemon of Khorne
"You have caused us great discomfort, little flea... And I feel inclined to scratch"

Kulvain Hestarius of the Death Guard
"In the embrace of the great Nurgle, I am no longer afraid, for with His pestilential favour I have become that which I once most feared: Death."

Horus
"The creatures of the Warp are just "aliens" too, but they are not life forms as we understand the term. They are not organic. They are extra-dimensional, and they influence our reality in ways that seem sorcerous to us. Supernatural, if you will. So let's use all those lost words for them... daemons, spirits, possessors, changelings. All we need to remember is that there are no gods out there, in the darkness, no great daemons and ministers of evil. There is no fundamental, immutable evil in the cosmos. It is too large and sterile for such melodrama. There are simply inhuman things that oppose us, things we were created to battle and destroy."

Karazantor the Vile, The Traitor of Xian
"Do not ask which creature screams in the night,
Do not question who waits for you in the shadow.
It is my cry that wakes you in the night,
And my body that crouches in the shadow.
I am Tzeentch and you are the puppet
That dances to my tune."

Khârn of the World Eaters
"Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn!"

Azariah Kyras
"Faithful... enlightened... ambitious... brethren.
In but a single decade- a few mere swipes of the pendulum- we have gathered a sacrifice to Khorne that will be made legend.
Though it was a simpler, weaker voice that illuminated me during my centuries upon the Judgment of Carrion...
... it was Khorne's messenger who showed me the true path of freedom from our pathetic corpse Emperor.
And what is this path? This meaning, this purpose to which we gather the skulls of our foes?
It is nothing. There is no meaning, no purpose. We murder. We kill. It is mindless savagery, this UNIVERSE is mindless.
In mere hours, billions will die! Innocent! Guilty! Strong and weak! Honest and deceitful! ALL of them!
They will scream, they will burn, and for no purpose but that mighty Khorne may revel in their bloodshed!
And united in this void of purpose, fear, or duty... we shall at long last be free!
Blood for the Blood God! Skulls for the Skull Throne! Let the galaxy BURN!!!"

Kor Phaeron
"Victory attained through violence is victory indeed. But when the enemy turns on itself- that is the essence of true, lasting victory."

Angron
“War is only won when every enemy is dead. A pacified enemy is still an enemy”
“Listen to your blue-clad wretches yelling of courage and honour, courage and honour, courage and honour. Do you even know the meaning of those words? Courage is fighting the kingdom that enslaved you, no matter that their armies overshadow yours by ten thousand to one. You know nothing of courage. Honour is resisting a tyranny when all others suckle and grow fat on hypocrisy he feeds them. You know nothing of Honour.”

Ahriman.
"Knowledge is power, but power is nothing without purpose. You may hold in your hand the power to remake all things, but if you do not know what you would change, you hold nothing at all"

Unknown speakers/generic quotes
"Shackle the soul and forge the flesh. Bind the machine and butcher the rest."

"Blood for the blood god! Skulls for the skull throne!"

"From the eye of terror we have come to kill!"
