Warhammer40k Stories

What if the biggest trickster in Warhammer found someone even crazier? People have transmigrated into Primarchs, psykers, Inquisitors, and even Orks, Necrons, and Daemons. But no one has ever become a Harlequin. Reborn shortly before the Fall of the Aeldari, our protagonist has no intention of becoming a hero. He has a far more ambitious goal. To create the greatest joke the Warhammer universe has ever witnessed. Expect absurd schemes, relentless trolling, impossible adventures through the Webway, and enough chaos to make even Tzeentch question his own plans. The Imperium? Fair game. Chaos? Even better. The galaxy? It won't know what hit it. Can a Harlequin convince a Daemonette to embrace purity, teach a Bloodletter pacifism, force a servant of Tzeentch to tell the truth, or persuade a follower of Nurgle to take a bath? Probably not. But watching him try will be glorious. "Harlequin, Harlequin, ... born to make the entire galaxy laugh." ........

In an alternate Warhammer 40,000 universe, a modern-day fan‑fiction author is reborn as Alexander, the long‑lost Second Primarch.

Wait... the Empress?!

Title 2: I Wanted the Wolf King, but I Got the Warmaster Before the Fall. Transmigrating into the most despair-inducing Underhive wastes of the 41st Millennium, Kaelen, a mere mortal, thought his days were numbered. When his cheat system finally activated, he prayed for one thing: Just give me Leman Russ. I need the Wolf King to survive! [Ding! System error. Target locked: Davin. Salvaging soul...] Instead of the loyalist Wolf, a dying giant crashed before him, his soul teetering on the edge of Chaos corruption. It was the Warmaster himself. Horus Lupercal. Staring at the tragic, uncorrupted demigod covered in scars, Kaelen went completely silent. "Horus," Kaelen sighed, pushing up his goggles. "Your father is a corpse on a golden toilet, your brothers have all gone insane, and the Imperium is a rotten hell-hole." Horus: "...?" No divine bloodlines. No genetic enhancements. Just a mortal commander armed with future knowledge, a glitchy system, and the most powerful Primarch in history serving as his loyal sword. If the galaxy is broken, they will carve a bloody path from the Underhive to Holy Terra to fix it. 🩸 [The Ultimate Fix-It]: Erasing the tragedy of the Heresy. Horus never falls, and the traitors will bleed. 🧠 [Mortal Domination]: Watch arrogant Space Marines and Chaos Daemons experience absolute cognitive shock when outsmarted by Kaelen's ruthless modern strategies. ⚔️ [Purging the Dogma]: Slashing heretics, kicking the Golden Throne, and reviving the Emperor's true dream. 👑 [Building a New Order]: From a desperate survivor to the shadow ruler of the Indomitus Crusade.

Under the blessed protection of His Majesty: On June 1, M30.890, we discovered a unique world in the Mists Sector near the Agaro Star Cluster within the Imperial Obscurus Sector. This world can only be reached through a dimensional rift located on a Death World designated SCH1233. Its specific coordinates are unknown and the astrogational data for this world does not match any existing archives, making it impossible to determine the distance that must be traversed to reach it. This rift doesn't seem Warp-related or caused by any Dark Age of Technology relics, and its principle remains unconfirmed for now. Upon arriving at the rift's destination, we discovered human natives. Their cultural development is definitely feudal era and the environment is habitable, potentially suitable for terraforming into a Garden World. However, this world is currently facing a threat from a Tyrannical Sorcerer. Interestingly, humans on this world can communicate without any language barriers. The underlying principle is currently unknown and requires further research. This world possesses significant developmental value. Imperial citizens in nearby star sectors, if you receive this message, please provide us with assistance. Attached are the specific coordinates... ______________________________ Note: The story took place somewhere after Volume 16 of the Light Novel

The Imperium of man begins a genocidal crusade aimed at wiping out the New Republic of Hyrule and its UNSC allies with other factions stepping in as the war drags on

Disclaimer: This is an AU Warhammer with some lore details that are heavily inspired by @Sagas1023 story. ______________________________ It was the 31st Millennium. Mankind faced one of the bloodiest wars ever witnessed not only by the galaxy, but by the universe itself. For tens of thousands of years, humanity had lived in what many believed to be a perpetual utopia, a golden age born from technological wonders beyond the imagination of lesser civilizations. Alongside their ancient allies and former rivals, they built a vast alliance that spanned the entire galaxy and reached heights that seemed impossible. But even such a civilization was not eternal. From beyond the known dimensions came an unknown and endless race of abominations that consumed every corner in the universe. One by one, stars went dark, galaxies were reduced to nothing and entire civilizations that had lived for millions of years were wiped away. After 100 years of desperate war, the surviving remnants of humanity and their allies made one final attempt to escape extinction. Using a device forged from the combined genius of human and xeno technology, they tore open reality itself and fled from the tendrils of the Great Blight that unraveled creation itself. But an incident happened. Instead of merely crossing into another universe, the refugee ship was thrown through infinite dimensions until it arrived in a new multiverse, one whose laws and systems were completely foreign to them.

I had a thought. so I made it. or making it.

The end of the world is the best thing that could have happened. It allowed all sorts of fun things to happen. Like the beginnings of a Cult in the name of Khorne. BLOOD FOR THE BLOOD GOD. Don't take this seriously. One-Shot.

(some few inspirations from sagas1023) In the chaotic and vibrant neon lit roads of New Eridu, the last remaining city on earth, home to millions of people as the last remnants of humanity huddle into one last bastion that stands against the hollows. In a turn of events a mysterious meteor crashes into the outer ring, but to those of excellent vision, the 'meteor' was too strange to be a meteor, it felt too smooth, it's movements too deliberate. As the city meets giants clad in yellow and gold bearing an aquila never before seen, hailing from a home far into the stars. Things begin to change. 6/1/26 no1 - #Imperium of Man 6/20/25 no1 - #tech

While en route to the planet of Arkhona, an old fortress world under the Imperium of Man, Kleon Stephanos, a deadly champion of the Word Bearers prepares himself to invade the unsuspecting Imperial World.

A normal Warhammer 40k fan while listening to some majorkill videos talking about the emperor and his sons. Thought to himself, "Wow the Emperor was a dick, I bet I can do better." Yet he never imagined a certain dick would take it personally and drag him into the 40k verse to stand by those words. Note: I'm completely new to writing so my format will be weird until I get used to writing. I'm writing this because I'm a huge WH:40k fan and I've always wanted to write something myself. I've been learning lore in my off time but there's still a lot I don't know. So don't expect any diamonds here, just inconsistencies.

Torn from the grim darkness of the 41st millennium by a catastrophic Warp rupture, Sister Ephrael Stern-the Daemonifuge-awakens in the burning sands of Jakku one year before the rise of Starkiller Base. Armed with faith-forged power, black-and-gold battle plate, and an alien psychic might, the zealot of the Adepta Sororitas crashes directly into the life of Rey, a lonely scavenger surviving among ancient wrecks. What begins as a fragile alliance of necessity rapidly turns into an intense, slow-burn romance between two women who understand the crushing burden of isolation and chosen destiny. Ephrael's presence accelerates Rey's awakening and fundamentally rewrites the coming galactic conflict, bringing ruthless Imperial combat doctrine to the Resistance and drawing the personal gaze of Supreme Leader Snoke. As the First Order mobilizes, Rey must balance her growing connection to the living Force with Sororitas discipline, while Ephrael is forced to confront whether love can exist alongside absolute faith. When Starkiller Base rises, the timeline fractures completely-and it is the Daemonifuge, coiling with white fire and wielding a blessed blade, who stands against Kylo Ren in the snow.
