"A shield impregnable against the encroaching darkness; a blade forged in defiance of fate! Let them be my legacy to the conquered the Milky Way, and the last gift to the humanity I failed to protect."
— The Human Emperor
Chaos's corruption of humanity will never end. Even the exalted Primarchs, personally created by the Emperor, could fall and betray the Imperium under the temptation of Daemons.
The Emperor was acutely aware that the Imperium needed an army more loyal and sharper than the Space Marines. So, before His final confrontation with the traitor (rebellious son) Horus, He bestowed upon humanity its last gift!
They are the most powerful force against Chaos Daemons, with a seed completely different from the 20 Primarchs. With faith as their armor, devotion as their blade, and purity as their weapon!
Thus was created Legion Number 666.
Codename: Grey Knights.
A mysterious and deadly force, no living person knows the exact origin of the Grey Knights. Even the existence of the Grey Knights is known only to a select few high-ranking individuals within the Imperium, such as a small portion of the Imperial Warmasters, the High Council of Terra, and high-ranking members of the Inquisition.
This is because any mortal who has seen a Grey Knight—such as Battle Sisters, Imperial Navy personnel, or even nobles and Commissars—will be silenced by these ruthless, iron-blooded warriors.
Kenmyo Isayama once heard a joke:
The Astra Militarum is resisting an attack from Chaos Daemon enemies when they suddenly receive two messages:
"Good news: Reinforcements have arrived."
"Bad news: It's the Grey Knights."
There's no way to continue the fight; they're going to die no matter what.
If an Astartes Monks accidentally sees them, the Grey Knights will erase his memory.
Any battlefield where Grey Knights are deployed is inevitably the most cruel and bloody apocalyptic war; they are a crucial force for turning the tide.
"This is too exaggerated…"
Before Kenmyo Isayama appeared six orbs of light, covered in violent psychic energy. Inside them were the Daemonhunters' reinforcements—Grey Knights.
There were six in total, meaning there would immediately be six top-tier Grey Knights.
Kenmyo Isayama's mouth unconsciously dropped open wide in astonishment.
Not only was he surprised by their efficiency—Kenmyo Isayama had barely finished speaking when these Grey Knights almost instantly teleported here, crossing an unknown distance.
Moreover, as a mid-to-high-level Psyker, Kenmyo Isayama could more intuitively judge the power of these Grey Knights.
Their psychic level was so terrifying that Kenmyo Isayama's soul trembled. If his own psychic power was a firefly's glow, then even the weakest among the six was like a stellar, solar furnace.
Every Grey Knight is a Psyker, and furthermore, they are of the highest level in the Imperium's twenty-four tiers: Alpha-level Psykers.
Alpha-level Psykers possess a psychic level capable of manipulating countless stars in their palms; plucking the sun, moon, and stars is truly not a dream.
"This is too absurd."
Kenmyo Isayama unconsciously opened his mouth wide and spoke a second time, which shows how much the Grey Knights had shocked him.
The halos had not yet dissipated, but the six hundred and sixty-six words of the Holy Litany, simultaneously recited by the six Grey Knights, had already begun to resound. Some call it the Daemons' bedtime lullaby.
Singing praises of the Emperor's sacrifice,
We, too, shall do the same.
We are the hunters of Daemons,
And shall persevere in His name.
We are the guardians of souls,
And shall walk in darkness.
We are the seekers of the unclean,
And shall make the destruction of evil our duty.
Just listening to their recitation, so devout that the loyalty contained within it was beyond words, sent shivers down Kenmyo Isayama's spine.

Under the suggestion of the Alpha-level Psykers, everyone would unconsciously follow their instructions; insubordination was impossible.
"Thud" x6
These "gods" landed almost simultaneously, their heavy armor immediately cracking the solid floor tiles upon impact.
Grey Knights, true to their name.
Grey tin cans. The armor they wore was, among all the power armor Kenmyo Isayama had seen, the coolest and most formidable set.
Baroque ornamentation adorned this Aegis-pattern power armor, making it appear sacred and noble, yet also full of grandeur. The Grey Knights' entire armor is anointed with holy oils and carved with sacred prayers, which makes the wearer's will impregnable.
Under the powerful psychic influence of the Grey Knights, these activated sacred prayers effectively protect them from the Warp and psychic corruption. They can also disrupt the spellcasting of hostile Psykers, preventing them from drawing power smoothly from their Warp masters.
However, their hands are usually left free, typically for the Grey Knights to wield more deadly force weapons like power swords and psychic halberds.
This is the epitome of absolute power: the Grey Knights, with their strict discipline.
"You just love to play god!!!"
Not having received the favor of her master, Lucius the Eternal, the Fallen Sister possessing the Arch-Confessor Brino Harwell, reacted with an outburst upon seeing these awe-inspiring grey tin cans.
In an instant, a decaying angel, filled with a corrupted aura, appeared directly above her. It had tattered wings, a vicious mouth filled with sharp teeth, and eyes that glowed crimson.
If the true Arch-Confessor Brino Harwell manifested as a holy angel, then the Fallen Sister manifested as a Slaanesh angel.
"Die!"
Looking incredibly flamboyant, the Slaanesh angel swooped down towards one of the Grey Knights.
The Grey Knight near Kenmyo Isayama was targeted. He could even see the "Book of Truth" embedded in the armor shimmering.
In response, the armored figure simply raised the Nemesis Force Halberd in his hand. With a terrifying output of psychic power, white lines appeared on the Nemesis Force Halberd.
The Grey Knight merely raised his blade and lightly swiped it through the air, "Whoosh," the air itself was cut. The Slaanesh Sister, far above in the dome, was instantly bisected. After a single strike, her chest gushed blood profusely.
And this single strike also affected Arch-Confessor Brino Harwell herself; a clear line of blood appeared, followed by a torrent of blood.
Even more terrifying, this one strike created a massive skylight in the ceiling above. Kenmyo Isayama could directly see the battleship macro-cannons of the Black Templars continuously charging above. It seemed they intended to use the macro-cannons to shatter Lucius's barrier.
"Six Grey Knights?"
Lucius raised an eyebrow. These emotionless warriors were his natural bane.
"I don't want to fight men I have no interest in."
He directly extended his palm towards Kenmyo Isayama. Immediately, Kenmyo Isayama felt something black entangle his feet, making him utterly unable to resist.
Kenmyo Isayama's balance was destroyed; this terrifying force directly dragged Kenmyo Isayama to the ground, seemingly intending to take him along.
"Pfft…"
A flash of a blade, and a small section of his foot, including the ankle, was severed.
It was Kenmyo Isayama himself who acted, saving himself.
Of course, those Grey Knights weren't to be trifled with either. Lucius had half a foot through the teleportation portal when a Grey Knight grabbed him by the scruff of his neck and pulled him back out.
