Though our tanks and artillery are mighty, it is the vast ranks of Imperial Guardsmen that shall trample the enemy to dust - let them come.
Lord Castellan Ursarkar E. Creed

A good soldier obeys without question. A good officer commands without doubt.
Tactica Imperium

Statistically, you will almost certainly die when assaulting a well-maintained fortress with a competent commander. You must strive to make your death useful.
Training Manual, Penal Legion

Ask not the Eldar a question, for they will give you three answers; all of which are true and terrifying to know.
Inquisitor Czevak

Trust not in their appearance, for the Eldar are as alien to good, honest men as the vile Tyranids and savage Orks. There is no understanding them for there is nothing to understand - they are a random force in the universe.
Imperial Commander Abriel Hume

I am a Commissar. I am empowered to deliver justice wherever I see it lacking. I am empowered to punish cowardice. I am granted the gift of total authority to judge, in the name of the Emperor, on the field of combat.
Colonel-Commissar Ibram Gaunt

Some place their trust in warships, and some in weapons of destruction. But we remember the divine Emperor. They are brought down and fallen; but we are risen and victorious.
Imperial Creed

We pray for our brethren who pilot the Dreadnoughts. Though they take new form, their souls, and their weapon mounts, remain pure.
Marneus Augustus Calgar, Ultramarines Chapter Master

If a man dedicates his life to good deeds and the welfare of others, he will die unthanked and unremembered. If he exercises his genius bringing misery and death to billions, his name will echo through the millennia for a hundred lifetimes. Infamy is always more preferable to ignominy.
Fabius Bile

They shall come, expecting the obvious, the simple, the artless. They shall stab at the shadows with confused minds and troubled hearts. Meanwhile, we shall appear unseen from ten directions, and from every one strike a fatal blow.
Farseer Caerys of Craftworld Ulthwé

Everything organic we know of is simply machinery, in one form or another. Tendons replace pistons; flesh in the place of steel; blood is simply biological coolant. To deny this and shun it is more than just Mechanicus orthodoxy; it is idiocy.
Adeptus Mechanicus Tech-Priest

It saddens me greatly that we must take arms against the peoples of the galaxy. By their deaths, they deny themselves the liberation that is only to be found in total surrender to the Greater Good.
Aun'Va, Tau High Ethereal

Some may be able to avoid the judiciaries of the Adeptus Arbites, fewer may be able to face off against the Imperial Guard and the Adeptus Astartes, but let it be known that none can stand against the Officio Assassinorum.
Officio Assassinorum

Why do we ride atop these elegant craft? The better to hear the screams of our prey as we ride them down, to savour the fear etched on their faces, to taste the tantalising tang of their blood in the air as an appetiser before the feast. But most of all we ride them so that the slaughter may begin as soon as possible.
Dariaq Bladetongue, Dark Eldar

We cannot live through this. Mankind cannot live through this. In a single day they have covered the surface of this planet with a flood of living blades and needle-fanged mouths. Kill one and ten take its place. Death! By the Machine God, Death is here!
Adeptus Mechanicus Magos Varnak, killed by Tyranids

That we, in our arrogance, believed that Humankind was first among the races of this galaxy will be exposed as folly of the worst kind upon the awakening of these ancient beings. Any hopes, dreams or promises of salvation are naught but dust in the wind.
excerpt from Dogma Ommiastra, on Necrons

By bolter shell, flamer burst and melta blast, the mutant, the heretic and the traitor alike are cleansed of their sin of existence. So has it been for five millennia, so shall it be unto the end of time.
Sister Immaculata, Adepta Sororitas

I have at my command an entire battle group of the Imperial Guard. Fifty regiments, including specialized drop troops, stealthers, mechanized formations, armored companies, combat engineers and mobile artillery. Over half a million fighting men and thirty thousand tanks and artillery pieces are mine to command. Emperor show mercy to the fool that stands against me, for I shall not.
Warmaster Demetrius

It is well known that destroying the more intelligent creatures in the swarm is essential to stop a Tyranid advance. Training in recognition and fire discipline is of some help in identifying the best targets but the chaos and confusion of the battlefield make it difficult for troops to pick out their targets amidst the swarming mass of creatures.
Inquisitor Agmar

When the people forget their duty they are no longer human and become something less than beasts. They have no place in the bosom of humanity nor in the heart of the Emperor. Let them die and be forgotten.
Adeptus Ministorum

I will never forget what I saw at Obsidian Station. The bones of five thousand brave men lay scattered about the winding corridors. Their blood was slick upon the walls and floors of the dormitories. Their innards were hung from control panels like grotesque decorations of some insane celebration. But not a single skull was to be found; taken as sick trophies by these despicable attackers.
Inquisitor Absolvus, speaking of Dark Eldar

How ironic it is that as fast as we spread progress and hope throughout the galaxy, the Tyranids spread death and despair. Only united can we hope to stand against them.
Aun'shi, Tau Empire

How typical that the humans should rely upon crude technology to protect them. How fitting that we, the Dark Eldar should kill them where they feel safest.
Kraegeth of the Slaughtered Heart

The Daemon has many forms. You must know them all. You must tell the Daemon from his disguise and root him out from the hidden places. Trust no-one. Trust not even yourself. It is better to die in vain than to live an abomination.
The First Book of Indoctrinations

Da only good 'ooman iz a dead 'ooman. An' da only fing better than a dead 'ooman'z a dyin' 'ooman who tell you where ter find 'is mates.
Morglum Necksnapper

What do Humans know of our pain? We have sung songs of lament since before your ancestors crawled on their bellies from the sea.
Farseer Eldrad Ulthran

May your weapon be guarded against malfunction, as your soul is guarded from impurity. The Machine God watches over you. Unleash the weapons of war. Unleash the Deathdealer.
Adeptus Mechanicus chant

As I looked into its dead black eyes, I saw the terrible sentience it had in place of a soul. Behind that was the steel will of its leader. Further still I could feel its primogenitor coldly assessing me from the void. And looking back from the furthest recesses of the alien's mind... I can only describe it as an immortal hunger. It is this that we cannot kill.
Chief Librarian Tigurius of the Ultramarines, speaking of Tyranids

It is too easy for an Eldar to embrace the obscene virtues of Chaos, for Slaanesh is nothing more than a manifestation of the Eldar mind in its most wild and unconstrained form. Human morality is meaningless to the Eldar. To an unfettered Eldar mind there is neither sanity nor madness, but merely a wave of perfect existence fulfilled by its own savage momentum.
Inquisitor Ralamine Mung, Ordo Xenos

Flesh and bone are weak and mutable, and yet the daemonic is ultimately insubstantial and impotent. To be master of both matter and energy, and blend this mastery with ultimate control of one's consciousness, is to achieve true immortality - neither confined by the material, nor divorced from it.
Magos Elizah Kaudge, heretic

And what are the achievements of your fragile Imperium? It is a corpse rotting slowly from within while maggots writhe in its belly. It was built with the toil of heroes and giants, and now it is inhabited by frightened weaklings to whom the glories of those times are half-forgotten legends. I have forgotten nothing and my wisdom has expanded far beyond mere mortal frailties.
Ahzek Ahriman, Thousand Sons Sorcerer

When it was over, when the blood had dried and the fires had died down, then we found we were the same as we had always been - small and terrified human beings, with only the light of the Emperor to see by in this dark galaxy of sin.
Saint Praxides

Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn! Kill! Maim! Burn!
Kharn the Betrayer, World Eaters

They are insignificant insects to be crushed. I fear no footslogger. No mud-covered infantryman can stand against the strength and speed that is within me and my Warhounds. They shall all die.
Esau Turnet, Warhound Titan Princeps

The minds of gods are not for mortals to know or to judge. Accept that Tzeentch has a place for all of us in his grand scheme, and be happy in the part you have to play.
Magnus the Red, Thousand Sons Primarch

Only when you have soared through the morning skies on wings of flame can you understand the Hawk. Only when you have fallen screaming upon those who know they are already dead can you understand the Banshee. And only one who has travelled but ultimately turned away from each of these paths can understand the Autarch.
Anthrillien Morningchild, Autarch of Yme-Loc

We are born for a darker purpose than that of mere existence. There will come a time when stygian night never ends, where dead stars will spread before us like islands that slumber on the ocean, and when the beings that hid like shadows will feed on us forever.
Adept Corteswain, shortly before his disappearance

That man is beset at all quarters by traitors, mutants and fiends is self-evident. But in truth none of these evils shall be our undoing. When the end comes it will be not at the hand of any mortal being of this or any other realm: death will come at the hands of the ancients, those who determined our fate aeons before we stood erect upon the holy ground of Terra and gazed up into the starry night.
Inquisitor Hoth

There is a cancer eating at the Imperium. With each decade it advances deeper, leaving drained, dead worlds in its wake. This horror, this abomination, has thought and purpose that functions on an unimaginable, galactic scale and all we can do is try to stop the swarms of bioengineered monsters it unleashes upon us almost by instinct.
Inquisitor Czevak, speaking of Tyranids

The Orks are the pinnacle of creation. For them, the great struggle is won. They have evolved a society which knows no stress or angst. Who are we to judge them? We Eldar who have failed, or the Humans, on the road to ruin in their turn? And why? Because we sought answers to questions that an Ork wouldn't even bother to ask! We see a culture that is strong and despise it as crude.
Uthan the Perverse, controversial Eldar philosopher

The daemonic are without number, and their legions span the galaxy. But faith does not tire. Should it take us an eternity, the Ordo Malleus will find and exterminate them all.
Lord Hephaestos Grudd

The Orks plague the galaxy from the end to end with their ceaseless warring and strife. They are a species rooted so deeply in war that peace is utterly incomprehensible to them. I pray with all my faith that some great catastrophe will annihilate them but I fear that ultimately it is they, not we, who shall rule the galaxy.
Xanthius, High Lord of Terra
