    Authors and Websites 

Uppsala Grimdark

  • Uppsala Grimdark is a blog where our 40K campaign is chronicled in short-story format with a dramatic storyline, interesting protagonists and tons of retouched images illustrating the writing. We are about 5 authors that collaborate on the writing itself.


  • A website created by a author who went on to become a Ascended Fan, no longer updated (domain has expired and the link is to an archive) but the stories are well worth reading. I particularly recommend The Killing and Please don't feed the Warboss.

The Librarium

  • The largest collection of Warhammer fanfiction in the net, some of which is rather good. I recommend the works of Chun, Conquering Light, Feil, Firefox, Launcifer, Nextdoor_Warlord and Squiggle.
    • With the forums gone as of the latest version of the Black Library site, most of the stories and writers appear to have moved to the Black Library Bolthole

The Conclave

  • A set of forums dedicated to the spinoff of Warhammer 40K, Inquisitor. Has a large role-playing section, where posters detail the efforts of the Emperor's Holy Inquisition, their antagonists, or sometimes just more "normal" people in the Grim Dark Millenium. Particularly worthy of note is the work Aurea Mediocritas

The Dornian Heresy

  • Recommended by Skritz, Eversor
  • Synopsis A Mirror Universe version of the Horus Heresy, with Rogal Dorn as the Big Bad (instead of Horus). Composed of multiple articles, and updated from time to time. Well written and worth reading.
  • Comments: Nurgle-dedicated Blood Angels (diseased and very vampire-ish), Khornate Space Wolves and World Eaters who got over their anger issues!
    • As different as it is, some things just do not change in this version of the Heresy. Despite being on the side of the angels relatively speaking, Abbadon still hates Horus, Ahriman still is trying to find his way to the Black Library, and so on. Unlike the original Heresy, the Imperium now has completely different flavors of traitor legions to deal with (the Tzeentchian Raven Guard are quite different than the original Thousand Sons, for example).


  • Recommended by Mr Terrorist
  • Synopsis A series of 40k short stories all set in the same universe. Common characters include Corsair Prince Eorlianeth Ansgar of Crescent Wings, Eldar Ranger Ellarian and Rogue Trader Merelen Cyierk.
  • Comments: SpartAl412 has created a unique Warhammer 40k universe which is Lighter and Softer and has some Cyberpunk influence. The most interesting character in these stories is Corsair Prince Eorlianeth Ansgar, a Reasonable Authority Figure Eldar who has made allies with the Tau, xeno-friendly humans and other aliens within his growing Empire.

    General Fics 
Stories focused on the family and the friendly relationships of the cast. Plot-focused stories or light day-in-the-life stories. Pretty much anything that isn't focused on romance.

  • Out of the Dark
  • Recommended by Omniscient 1
  • Status: Ongoing
  • Synopsis: The rebellion of the Men of Iron turns out to have been part of an Eldar scheme. Since by this point there's no way to stop it, a group of Dark Age humanity hides in a pocket universe for the next several thousand years while they try to rebuild. Now, this remnant of humanity's greatest heights has emerged into the modern 40k setting. To quote the author: "Oh Eldar, we're baaaack. NOS AUTEM TENEBRAS!"

The Commissar and the Leftovers by Sam Aint

  • Recommended by Enderheisenberg, Omeganian.
  • Synopsis: The daily life of a Ragtag Bunch of Misfits team in the Imperial Guard, available in both Russian and English.

Wishful Thinking by Sam Pardi

  • Recommended by souvikkundu25140017
  • Status: Complete, sequel is also out
  • Synopsis: An SI gets dropped into the Segmentum Tempestes with mutagenic powers, a chakra network and not much else. Can they evade accusations of heresy, burning the mutant and getting krumped by Orkz long enough to establish themselves and make a difference?

Ilmaea: A Novel of the Dark Eldar by Veriform

  • Recommended by Sepirahkt
  • Status: Complete
  • Synopsis: A crafty, vicious Sybarite, Suth Anax, takes advantage of her mistress's death by assuming her identity with the aid of an enigmatic haemonculus. Elevated suddenly to the pinnacle of Dark Eldar society, Suth performs a high-wire act above the knives of her enemies, her allies, and her underlings, because in Commorragh there's no rest for the wicked and no end to the race.
  • Notes: Despite what both the title and Synopsis imply, this is not actually a novel-length story. It is actually a short story, and it does NOT go beyond the main character assuming her mistress' identity. Do not read this expecting a story longer than six thousand words.

Rise of the Tau by Revenant

  • Recommended by Commisar 92, Baron Praxis
  • Status: Complete
  • Synopsis: A few hundred years after the current Warhammer 40K setting, the Tau Empire has come to dominate the Galaxy. They have shattered the Tyrannids, exterminated the orks, are closing the Eye of Terror, and are driving the Imperium back to Earth. Of course, not without a little help from a VERY old benefactor, the Void Dragon. This story is quite well written, and it ties up very nicely in the end, with many named character in Warhammer 40K lore getting a nice sendoff. The battle scenes are quite well done as well.
  • Now with its own TV Tropes page.

The Shape of the Nightmare to Come by LordLucan

  • Recommended by Whakamol, Extraintrovert, Icarael, Kurze Haunter, Baron Praxis
  • Status: Complete
  • Synopsis: What's worse than Warhammer 40k? Warhammer 50k. The God Emperor has perished, the Imperium is shattered, the Necrons reawaken, Chaos reigns supreme, and that's just the beginning.
  • Comments: Posted on a forum thread, so there is discussion between posts, but definitely worth a read. There aren't tremendous amounts of actual 'stories', but there is loads of detailed background fluff, which can make for hours of reading. The sheer amount of despair and horror can be unnerving at times, and the often Lovecraftian style of writing amplifies these elements. Basically this is to 40k as 40k is to Star Wars or Star Trek. Now has its own trope page.

The Evil That Men Do – a tale of a Heresy by machine3589

  • Recommended by souvikkundu25140017
  • Status: Vanished from the Internet, please post a link if found
  • Synopsis: It's about a still Loyalist!Horus who finds out about the future thanks to some Warp shenanigans bringing a derelict Strike Cruiser from the 41st Millennium back in time and his subsequent efforts to stop it from coming to pass.
    • Notes: Story in AH forums and requires an account in order to read.

ToyHammer by RougePsyker.

  • Recommended by Medinoc, USA Bobcat,Kurze Haunter, Baron Praxis
  • Status: Dead
  • Synopsis: Michael, a guy who plays 40k but is not a hardcore fan, suddenly finds a bunch of miniatures battling each other (they don't seem to be specifically his miniatures), and Hilarity Ensues.
  • Comments: This is a really interesting read. It starts out a little disjointed, but the writer quickly warms up, grows his beard and it evolves from a rather disjointed gag series into a really good read by chapter 8 or so. I'd recommend a rewrite for the first few chapters (which are funny, but a little off) but from then on it gets into something awesome. Also, from what I've seen in the reviews, a lot of people like this one. The Omake Collections are related and are as awesome as oneshots go.

The Misfits by davidnm2007

  • Recommended by Ugolino, Gentlemens Dame 883, USA Bobcat
  • Status: Dead (last update January 2012)
  • Synopsis: (Taken from the Pit) Alastar, Nasty and Patreus are training to be Space Marines - or trying to, anyway. Ever get bored of Chapter-zombie, personality-free, lemming-like marines? This is my attempt to avoid those tedious stereotypes. Now has its own page.
  • Comments: A fun read, in-character, and with great characters. Unfortunately, It's a Deadfic. One troper found the writer's take on the Ultramarines problematic, but it's a good read regardless of your feelings on that chapter.
    • Crull: While technically written well, the author's problems with the Ultramarine's characterization detract from the whole fic for me.
    • Cosmic-Behemoth: Just bloody cool in my opinion, all three of the title characters are fleshed out, interesting characters, Kodos is a gas to listen to; and I dare say there isn't so much as a whiff of chapter zombies or cardboard characters. Just a couple of Deus Ex Machinas, but the badassery surrounding them pretty well overshadows it.
    • USA Bobcat: Have followed this since infancy, and it has never stopped delighting me. The fact that the protagonist trio are so different is very intriguing, and even lampshaded in the story. Each of them bring a different POV to the tale, and character development is actually present. As well, the presence of a well-done Chaos Marine antagonist is also a boon, and the author makes it hard not to root for Chaos, perhaps a tad too much. The Space Wolves are amazing and hilarious, every appearance of theirs making you want to read more. The Ultramarines are portrayed a little dickishly, but to be fair, they demanded and received their own pocket kingdom. That's bound to have affected their judgment more than a little, and there are signs that even the Ultramarine jerks are good guys being manipulated, whenever they interact with the Storm Ravens. All in all, a wonderful story, I cannot recommend a better one.

Time of Ending: The 40k Finale by Nicholasakira

  • Recommended by Augustine
  • Status: Complete
  • Synopsis: This story is what happens when you skip ahead 3,000 years from the current time. The author's description says it best "13000 years after Horus, the Imperium is at its breaking point. The Space Marines are dying off and Chaos is ready to claim the galaxy. This is the story of the epic conclusion of the Imperium's wars for survival." Every single race is accounted for and the author switches between them throughout the story.
  • Comments: This story has not gotten the respect I feel that it deserves. The author mainly works with OCs due to the time period being changed. But the majority of the characters we know and love will make an appearance one way or another. However, there are some plot points that you may not be comfortable with, such as the Tyranids being the remainder of the Enslavers given physical form and the fate of the Unknown Primarchs. Overall, the author gives a well-done conclusion to the entire series, giving a definite ending to every race involved.
    • It was also once illegally published on because some bastard stole it. It's gone now.

Sons of the Fire by Colonel Mustard and Gaius Marius

  • Recommended by: Fire Beast
  • Vanished from the internet. Please post a link if found.
  • Synopsis: On the Eastern fringe, a planetary governor is about to commit a great heresy; leading his planet into the alien embrace of the hated Empire of the Tau. The Imperium cannot allow this to happen and send in two companies of Astartes to enact a great cull. One is from the unchallengeable tank masters of the Sons of Thunder, the other from the brutal Salamander descendants called the Fire Beasts. All of them are Sons of Vulkan but by the time this war is over, they will be at each other's throats.

Return of the Lost Primarch by drakensis

  • Recommended by: The Wandering Monster
  • Status: Complete
  • Synopsis: What if the swarming Tyranid invasions were nothing but rag tag fleets? What if someone was chasing them?
  • Comments: A darkly humorous short one-shot told from the perspective of one of the two Unknown Primarchs.

Unusual Alliances by steinerdavion2183

  • Recommended by: Arjac
  • Status: Dead (last update January 2016)
  • Synopsis: By choosing to save an Eldar Crop-production world (proper term?) from the Eldar's Dark Kin, an Ultramarine Captain sets of a domino effect within the entirety of the 40K universe.
  • Comments: Raw writing is competent, and raw plotting is too. The author rejects the canonical universe in his second chapters' reply to reviews, though, perhaps to attempt to cover up for his Theme Park Version of 40k, and the story never quite recovers from this as a work of 40k fiction though it's certainly a decent story for...something else?

Chronicles of the Burger Marines by purplefishman

  • Recommended by: Mr Terrorist, Baron Praxis
  • Status: Dead; last update September 2012
  • Synopsis: The Burger Marines... One of the strangest chapters of the Imperium... Dedicated to feed all the actors of the WH40K universe... There are thousands of strange stories that take place in their restaurants. Here are some of them.
  • Comments: A funny fic that focuses on the Burger Marines, a chapter dedicated to conquering their allies and enemies appetite by serving them the best fast food in the galaxy. Very hilarious on how the Burger Marines handle various customers who come to their restaurant and the customers themselves over food.

Dawn of Hospitality by That guy 83

The Brave Guardsmen of Spidera IV by Pooka

  • Recommended by Gentlemens Dame 883
  • Status: Complete
  • Synopsis: A group of PDF troops are reinforced by some... most unusual Imperial Guardsmen. Humour.
    • The saddest part is that one could believe that this could happen in the 40K universe. Also, makes Bureaucrats out to be more terrifying than literally every other faction in-game... read to find out why!

Madhouse, by Nuts!

  • Recommended by Wild Goose, Baron Praxis
  • Status: Complete
  • Synopsis: The Chaos Gods take turns to evangelise and preach their message. And an Imperial priest gives them the best Shut Up, Hannibal! ever.
  • Comments: Utterly brilliant, and perfectly captures the voices of all the players.

Cultist-Chan and the Glorious BolognaTown Groxburger Crusade

  • Recommended by roisaber, Baron Praxis
  • Status: Complete
  • Synopsis: Road trip! Join Cultist-chan and friends on a completely degenerate trip across the galaxy as they destroy an inhabited planet, narrowly overpower a little girl, hide from some very ill-tempered Space Marines, and permanently cripple an interplanetary conglomerate.
  • Comments: If you allow a child to read this novella, you are a bad parent or guardian.

Cultist-chan, Destroyer of Worlds

  • recommended by roisaber, Baron Praxis
  • Status: Complete
  • Synopsis: When Cultist-chan wins the spaceship of her dreams during a rigged raffle, even Khorne can find no reason to fault her when he witnesses the final outcome.
  • Comments: Black comedy from a deranged mind.

If the Emperor had a Text-to-Speech device

  • Recommended by Mr Terrorist, Baron Praxis
  • Trope Page: If the Emperor Had a Text-to-Speech Device
  • Synopsis: After ten thousand years, the Emperor of Mankind is finally able to speak to his subjects thanks to a Text-to-Speech device. However, the Emperor is extremely pissed of what the Imperium of Man has become and goes on a long, "colorful" critique over this.
  • Comments: A hilarious web videos series for all Warhammer 40k fans.

Secret War Warhammer 40,000, by Adrassil

  • recommended by Eversor
  • Status: Complete
  • Synopsis: After his organization is hired to hunt down an influential ganger on the Hive world, Omnartus. Attelus Kaltos is embroiled deeper into the complex world of the Assassin. This is the job which will change him, for better or for worse, forevermore.
  • Comments: I like this fic. It feels similar to a Dark Heresy campaign journal. Sometimes the writing can be a bit juvenile and there were some plot twists I didn't like, but in general, I felt that the writing is decent, the characters are interesting and the writer has clearly put a tremendous amount of work into writing it.

Warband of the Forsaken Sons, by Zahariel

  • recommended by Ikorios
  • Status: Complete
  • Synopsis: Horus Lupercal, Warmaster of Chaos, is dead, and the Traitor Legions run from the wrath of the loyalists. Amongst them, Commander Arken of the Sons of Horus gathers on his ship an army from the ranks of all Renegade Legions, and begins to plan his vengeance against the Imperium of Man ...
  • Now with its own TV Tropes page at Warband of the Forsaken Sons
  • Comments: this fic depicts how the Chaos Marines pursue the Long War against the Imperium. It has a lot of characters coming from different chaotic backgrounds and a great story.

Hunted, by Kate-Corvus Albus

  • recommended by Eversor
  • Status: Complete
  • Synopsis: Inquisitor Nicomedo of the Ordo Xenos follows an Eldar Farseer to a near lifeless world. Already Necrons are slowly awakening from their tombs, and the Inquisitor must find out how to deal with this new threat, without losing his prey forever. An unlikely ally emerges, an old friend comes to his aid and the deathless march.
  • Comments: This story takes some time to introduce all the characters and properly get going, but when it comes together it's an enjoyable tale of treachery, revenge and the need to prevent the Necrons from awakening and becoming a terrible threat to both the Imperium and the Eldar, with plenty of badass action scenes along the way. The author is from Germany and English is not her first language, not that you're likely to notice much given the quality of her writing. I recommend her other stories as well.

The Road to Disappointment, by Chandagnac

  • recommended by Eversor, capeclare2
  • Vanished from the internet. Please post a link if found.
  • Synopsis: In the grim darkness of the far future, there is only war. Nevertheless, Evarvae Uldanthyr hopes to find a better way, to enable her people to survive the 41st millennium and live in peace with mankind. Unfortunately for her, hope is the first step on the road to disappointment.
  • Comments: This story starts off as a lighthearted deconstructive parody and gradually takes on a more serious tone. Basically, Evarvae is a young idealist who wants to be a messianic hero and save everybody. In a more lighthearted setting she might actually be successful. However, this is Warhammer 40K...

The True Emperor of Mankind by Rith-Shadowbane

  • Recommended by wilji1090, Baron Praxis
  • Status: Complete
  • Synopsis: An Inquisitor of the Ordo Hereticus is told of an awful secret of the Imperium of Man and the Horus Heresy.
  • Comments: This presents an interesting fan theory regarding the God-Emperor of Mankind on the Golden Throne, the Horus Heresy, and the fates of the Traitor Legions and Primarchs. Definitely a worthwhile read.

The Lure of Chaos by GardenerKing

  • Recommended by Oddstar 6, Baron Praxis
  • Status: Complete
  • Synopsis: A dialogue between an Inquisitor and a Priestess of Chaos over the nature of Chaos and the true history of the Horus Heresy.
  • Comments: What's interesting is that we get to see things from the perspective of a Chaos-worshiper who is neither a psychopath nor a raving lunatic, and we get a very interesting revisionist take on the history of the Imperium and the Horus Heresy. At the same time, we are left wondering whether this is the truth, or a falsehood that she sincerely believes, or a lie that she is spinning to seduce the Inquisitor. There are enough hints in the text that it really could go any way.

Imperium Ascendant by Sulemain

  • Recommended by Milarqui
  • Synopsis: what if the Emperor had more empathy? What if he ensured his sons had no problems when they came to work with him? In short, what if the Emperor's most assholish actions never took place? The result: awesomeness as the Eighteen Primarchs continue to kick ass and take names, since the Horus Heresy never took place.
  • Comments: a very entertaining story where the Emperor's compassion (brought on by a discussion with Malcador the Sigillite shortly before the Crusade begins) towards his children becomes the key to secure the universe and ensure that the Imperium does not fall to Chaos. Highlights include an attack on Commorragh (the Dark Elves' only city), a duel between brothers and even a couple of A Song of Ice and Fire cameos (because Planetos turns out to be part of the WH40k 'verse). The only bad thing is that it is Dead, but Sulemain has promised to attempt a second run soon. You also need an Alternate History account to access it.

Glory or Death by Swordomatic

  • Recommended by WildGoose
  • Status: Dead (Last updated jul 15, 2015)
  • Synopsis: A quest following the trials of the Crimson Crusaders, a Blood Angels sucessor chapter in the 42nd Millenium.
  • Comments: Very entertaining, following the story of a fledgling unconventional chapter of Space Marines through their successes and losses.

Age Of Strife by Academia Nut

  • Recommended by Rancor
  • Status: Complete
  • Synopsis: A quest set only generations after the gestation of slaanesh ended warp travel, Age of Strife follows Dia Stone, a Warrent Officer who found herself in charge of a small research outpost in the wake of a nuclear apocalypse, in her struggle against both human malevolence and supernatural influences.

Avoiding Stupid Deaths in the 41st Millennium by erttheking

Deus Ex Mechanicus Reboot by Arankor

  • Pairing(s): None.

Be All My Sins By deadcrystal

  • Recommended by The Gentlemen
  • Status: Dormant (last updated July 2017)
  • Synopsis: A goth girl gets dropped onto an imperial planet during a chaos attack. Things go about as well as expected. Soon captured, singled out and recruited, watch as her own morals decay and spiral out of control, like a slippery slope covered in blood and terror... and daemons.

Imperial Von Neuman by Andoriol

  • Recommended by Rhodes 7
  • Status: Ongoing
  • Synopsis: A Self-Insert as a lowly tech-priest. One who accidentally/on-purpose ends up stealing an Imperial Knight to survive a Chaos invasion, leading to his sort-of joining an Inquisitor's entourage.

Crimson Dawn by Spartan-168-Django

  • Recommended by Mr Terrorist
  • Status: Dormant; last updated February 2018
  • Synopsis: It seemed like just another routine military operation for the Imperium: their forces were in the process of landing and retaking a rebellious planet. But when a Warp anomaly strikes, the fighting men and women of the Imperium suddenly find themselves transported across time and space to a new world: Holy Terra itself, but at a far earlier time. This is 1984.

This Won't End Well by Stranger Orders

  • Recommended by Arbitrary Justice
  • Status: Ongoing
  • Synopsis: A Self-Insert as a Primarch who is thoroughly aware of how doomed he is. A Self-Insert into a Primarch is nothing new but this one is interesting in that the consequences of sticking a normal person into a demigod are well-explored. Has a few issues (spelling for one) but the plot is really interesting. Notable for some interesting takes on canon material (including a rational Mechanicum) and a great deal of world building (including a Adventure-Friendly World homeworld with a Dungeon-Based Economy)which makes it a worthwhile read.

Bound Fate

  • Recommended by Tomas Goes Yas
  • Status: Complete
  • Synopsis: Warhammer High setting, following the Ordo Oficio assassins as they safeguard the Primarch's Daughters. Develops the characters beyond the maniacal murder machines seen in the lore, and sets up a really great series of plot threads. Does feature quite a bit of romance, but it's all wrapped up nicely. Also on 1d4chan: here.

Imperium Ascendant (Heresy-less 40k) by Jayfiction

  • Recommended by Duckling, Azorius 24
  • Status: Ongoing
  • Synopsis: The abduction of the infant Primarchs is stopped by an intervention from the Grimdark future of the 41st millennium, leading to a different path for the Emperor and the Imperium. The author, Jayfiction has quite a few interesting ideas about the Warhammer 40000 universe and how it works which is well-displayed in this story.

The story can be found on here.

Embers in the Dusk by Durin (with a couple thousand omakes by other authors).

  • Recommended by Omeganian
  • Status: Ongoing
  • Synopsis: It is the late 43rd millennium. You are an Administratum clerk, assigned as the new Governor of a planet. It was supposed to be a regular debt-ridden Agri-World; instead, what you got was the deadliest Deathworld in the Imperium. Teleporting spiders with poison that kills you in a second, laser spitting kaijus, stampeding herds that can trample a tank regiment, nuke-spitting island-sized turtles... and that's the safest part of the planet. Doesn't sound bad yet? Well, how about the fact that, a few decades in, the Astronomican goes out...

Return of the Second Primarch by Naranka

  • recommended by: VictorioMWolff-Haddock
  • Status: Ongoing
  • Synopsis: Amidst the darkness of the grimdark 41st Millennium, what if a forgotten son returned from outside the galaxy to bring back hope?
  • Comments: Man of Kryptonite to Magnus the Red and Bash Brothers to Mortarion, Lukaen The second, Primarch of the Shrouded Heirs, are unique and feared the most by the Chaos Gods because he and, by extension trough his Gene Seed, his Astartes, are Blanks. After centuries missing, he has finally return to rejoin the Imperium of Man.

Everqueen by Ashynarr and Skyborne.

  • recommended by: Omeganian
  • Status: Ongoing
  • Synopsis: During the Rise of Slaanesh, Isha manages to flee the Chaos Gods, and finds herself on Terra. How differently would history proceed with her aiding the Emperor in healing Terra... and keeping him a bit less pragmatic?
  • Comments: Somewhat intermittently updated, and with a chapter or two on Patreon.

The Mortal Son by FreedomOfThinking.

  • recommended by: Azorius 24
  • Status: Ongoing
  • Synopsis: Entombed on the Golden Throne, the Master of Mankind has been near helpless to combat the dangers humanity faces. So, he decides to try something new. And on the quiet, isolated Agri-world of Helios, something wonderful happens. A boy, named Lucian, is born. However, when the Ruinous Powers arrive on Helios, a galaxy-shaking chain of events is put into motion.
  • Comments: Very well-written, with some cracking battle scenes (especially those displaying just how terrifying fighting an Ork WAAAGH! really is) and interesting characters, from Lucian himself, an ordinary(ish) kid who just happens to be able to kill several hundred people with his mind, an oddly cheerful Inquisitor, a grumpy old cyborg Arbites who is nowhere near as coldhearted as he wants you to think, and the last surviving members of the Astral Knights. Also manages to strike a decent balance of grimdark enough to be very much in the spirit of 40k, but with enough lighthearted moments to avoid being genuinely bleak.

    Crossover Fics 
Stories which crossover with other characters or works.

Star Wars vs Warhammer 40K by AFanWithTooMuchTime

  • Recommended by: CryptoPenguin
  • Crossover with: Star Wars
  • Status: Ongoing
  • Synopsis: As the Clone Wars draws to its final year, the era of the Dark Imperium has begun, as Guilliman recalls as much of the Imperial forces as he can to launch the Indomintus Crusade. A massive Imperial Sector Fleet along with several Space Marine Chapters and its fleeing population failed to meet up for their great counter attack and are thrown through the warp to a Galaxy Far far Away. With no way home and an entire sectors worth of refugees to care for, the Imperial forces must now explore and conquer this new galaxy and create a new home for themselves, at the expense of its native inhabitants. But the natives are not going to go down without a fight and might just surprise the Imperials in more ways than one.
  • Comments: A fairly new story but one with more than 18 episodes, and while its based on a overdone crossover between 40K and Star Wars, its by far the most well made, this story does not favor one franchise over another something that is often seen too many times in crossovers. Both sides were written in respect to both their advantages and disadvantages over each other, and it is made clear that despite one franchise being superior over another, an actual well written crossover story does not mean the story is a complete power trip for one franchise over another. The writer clearly has done his homework in both franchises, and shows a deep knowledge in both universes and has crafted clear and well connected arguments that has thus far been able to bind both universe together seamlessly. By far the best 40K/Star Wars crossover work ever made. So far its an audiobook with amazing sound effects and voice acting that you might have thought this was an official work. Hopefully he would uploaded his work onto or as well and gain more viewers, and could use a proper title as well.

Cancer, by Jonas Grant

  • Recommended by: demonwarlord
  • Crossover with: [PROTOTYPE]
  • Status: Dormant. (Updated May 22, 2018)
  • Synopsis: "You know why selfishness is a stupid concept? For the same reason cancer cells are always doomed; they consume everything, feed off their host and take all there is to take for themselves, then, the host dies and the cancer with it. No matter how large and deeply implanted it is, the selfish will die with the rest of the world. That's why you should get to work now."
  • Comments: a Crossover between Warhammer 40000 and Prototype that starts with a dockworker being told he is going to die of cancer in 6 months, something happens to him and he wakes up 7 months later with no idea what has happened in between then and now and in the middle of an invasion. The story is entirely told from his perspective and seems kind of stream of consciousness with some snark and a semi-quickly advancing plot.

Lovehammer by Arkado

  • Recommended by: SAMAS
  • Crossover with: Sailor Moon
  • Status: Dead
  • Synopsis: Queen Serenity's attempt to send her daughter and the Senshi into the future was spoiled at the last minute, sending the Princess lost through time and space. In an alternate Earth far into the future, the reborn princess is discovered by the God-Emperor of Man, who has just conquered unified the planet. Realizing the power sleeping within the child, he adopts the Princess as his daughter. Thousands of years later, Ciaphas Cain, HERO OF THE IMPERIUM! discovers a stasis pod containing Hotaru, known to the Imperium as the Anima of Saturn.

Lovehammer Inc by Various Authors

  • Recommended by: SAMAS, Dame-Amaryllis
  • Crossover with: Sailor Moon
  • Status: Dead
  • Synopsis: Taking the same concept as the above (Neo Serenity raised by the Emperor Of Man), Lovehammer Inc focuses primarily on the time of the Great Crusade. As Serenity and her Father travel across the galaxy to find the lost Primarchs, they also find many of them in the company of several remarkable young women, as friends, family, or even lovers. Whatever fate brought the Princess to this universe, the Senshi have come to serve her as well.

In the Beginning, There Was Man by torrmercury

  • Status: Discontinued
  • Synopsis: The End Times have comes, the death of the galaxy is here, the final victory of the Chaos Gods draws near but the God Emperor of Mankind is not willing to let Humanity die and tremors of power within the Warp just may the key to saving His people.
  • Comments: The story is actually a roleplay game on the site Sufficient Velocity, players as the God Emperor of Mankind must deliver Humanity from the multitudes of threats within the Warhammer 40k galaxy and lead them into another Universe.

The Culture Explores 40k by jseah

  • Recommended by: Pantegral, Azorius 24
  • Crossover with: The Culture
  • Status: Dead (last update July 2015)
  • Synopsis: A small fleet of Culture ships arrives in the Warhammer 40k galaxy and tries to overcome Grimdark while dealing with the Outside Context Problem of Chaos. Hilarity ensues. Including, but not limited to, a Special Circumstances archaeological dig on a Necron tombworld, multi-party future sight gambit pileups, serious upgrades to the Tau, fun with the Dark Eldar, some subtle influence in the Imperium of Men, and a hell of a lot of dead Tyranids.
  • Comments: What happens when the most grimdark and most utopian universes out there collides? This fic has the answer. An easy-to-browse version can be found on AO3; a slightly more up-to-date list of updates is here. At 175,000 words and rising, some Archive Panic is to be expected.

Reflection in Steel by Commissar Rasher

  • Recommended by: Tabula Rasa
  • Crossover with: Halo
  • Status: Dead (last update February 2015)
  • Synopsis: The UNSC Wotan is the finest ship ever built by human hands. But now its crew faces the greatest challenge of their lives. Trapped in a strange land, they must survive and try to find a way home in a dark galaxy where there is only war.
  • Comments: Following a diverse cast of characters from both sides of the crossover, this story avoids some of the common problems of crossovers I've seen. Neither side is overpowered and the characters never use meta knowledge of the setting to counter each other, also noted for not having the UNSC characters become friends with anyone in 40k, and not using the setup as an excuse to have Spartans fight Space Marines. The story is also available on SpaceBattles where it updates more frequently, in small chunks rather than the massive 10-20,000 word chapters the author uploads to
    • Last updates to the spacebattles forum is March 2015, presume it as abandonded fic status as author has worked on other projects.

Hammerhand by Colonel Mustard

  • Recommended by: Fire Beast, hodaza, Iowaforever
  • Crossover with: Mass Effect 2
  • Status: Complete
  • Synopsis: While on their way to battle the Greenskins, Captain Malleus of the Sons of Thunder and his command squad are hit by a shock attack gun and blasted all the way back to the early 3rd millenium. Shepard is dead, human colonies are disappearing and its time for the Astartes to do what the Astartes were made to do. Long, well written and complete with a sequel already started.

The Mission Stays the Same by Ursakar

  • Recommended by USA Bobcat, MetalKing1417, chankljp, Eversor, Theriocephalus
  • Crossover with: Mass Effect
  • Status: Ongoing; the story was originally discontinued due to author burnout, but was taken over by a different writer post-chapter 20.
  • Synopsis: Just after Shepard comes back from Project Overlord, days after regaining life, EDI detects a signal from the nearby planet Aite. When Shepard investigates, she finds a very confused Imperial Guard Stormtrooper and an Eldar Farseer.
  • Comments: I found this a quite interesting crossover. Captain Gallardi (the Stormtrooper) incorporates Mass Effect technology in his gear, such as Mass Effect style armor, but also keeps his hotshot lasgun, which bypasses kinetic barriers. The technology issue gets taken care of quickly, but I found that everyone was in character, Gallardi having been part of an Inquisitor's retinue and thus slightly more easy with Xenos. He still refuses to allow Mordin to inspect his weapons or armor, though he eventually starts warming up, he has not yet lost his xenophobia entirely. Shepard is female, and follows most of the Fanon Fem Shep ways, but is very much a character, not an insert. Maeteris (the Farseer) has not joined the team on a ground mission yet, and focuses more on seeing the future, though in typical Eldar fashion, will hint and nudge Shepard, but never tell her outright.

Big Sister by Academia Nut

  • Synopsis: On the planet Nocturne, The Blacksmith N'bel is greeted by the child who will one day become the Primarch of the Salamanders, but he doesn't arrive alone.

Shinji And Warhammer 40 K by Bluepencil

Thousand Shinji by Academia Nut

  • Recommended by Neon Genesis Evangelione, Gentlemens Dame 883, Earth Scorpion
  • Crossover with: Neon Genesis Evangelion (different from Shinji And Warhammer 40 K because it's an actual universe crossover rather than the boardgame making an appearance.)
  • Status: Complete
  • Synopsis: Shinji is his father's son, and with a little mentoring from an unlikely source, he will learn the ways of plotting and scheming, along with a few other useful skills. Gendo is so screwed. And so is everyone else.
  • Comments: Where there's smoke Shinji And Warhammer 40 K, they pitch back Thousand Shinji. I'll second Thousand Shinji, if only because of the final passage, which is an absolutely hilarious riffing of the "summary" that prefaces the Warhammer 40,000 books. Though it of course has more merits than just that.

The Circle Must Be Broken by Todeswind

  • Crossover with: Babylon 5
  • Status: Dead (last updated February 2017)
  • Synopsis: Inquisitor Daul is hunting down the dangerous heretic Soren Faust on the planet of Belzafest. Faust, the supposedly long-dead traitor Inquisitor Lord, infamous for close to a century for his wild genetic experiments and insane philosophies, has taken world hostage and is planning something insidious. Aided by the former Skitarii Cairn Thross, the Magos Kerrigan, the elite soldiers known as the Lionhearts and reluctantly aided by the Rogue Trader Nathaniel Emanuelle Sáclair, Daul is about to discover secrets far beyond the scope of what he was prepared to manage and is going to have to find his place in a wider world than he had ever believed existed in a war for the fate of humanity long before even the Dark Age of technology. Babylon Five is a haven for warriors, idealists, dreamers, and wanderers. How much damage can one more ship of fanatics do in the long run?
  • Comments: First five chapters focus on the Warhammer 40k aspect with only hints at Babylon 5; however, the later chapters are more obvious crossovers.

Elsewhen, and Elsewhere by The Lycanthrope

  • Recommended by corin
  • Crossover with: Star Trek: The Next Generation
  • Status: Dead (last update January 2013)
  • Synopsis: The pirate vessel Free Enterprise has preyed on Imperial shipping for years, but when the battlebarge sent to bring it to heel is dragged 38,000 years into the past, the existence of the Imperium is threatened. In the 3rd, as well as the 41st millennium. Alternates between a single Space Marine battlebarge lost in the Star Trek galaxy and the battle between Imperium forces and the Tyranids at Istvaan.
  • Comments: Does a brilliant job showing the vast, vast technogical disparity between the two universes, as well as the clashing mindsets of the idealistic Federation and the much grimmer Space Marines. Also captures the essence of the Space Marines quite beautifully. Also, the chapter where the Space Marines take on the Jem'Hadar and thoroughly curbstomp them is a thing of absolute beauty. Updated January 2013 after a long hiatus.

Chains Of The Kindred by Solvdrage

  • Recommended by eljonno
  • Crossover with: Halo
  • Status: Dead (last update July 2016)
  • Synopsis:Packed full of Ultimate Showdowns, such as Titan vs Scarabs, Space Marines vs Covenant, and, of course, Tyranids vs Flood. Running through the whole thing is a massive Chaos corruption, and The Reveal of The Emperor himself. Unfinished as yet.
    • There are a few problems to be found though, such as the comparison between Kasrkins and Helljumpers that would make any proper Cadian player just bang his head against a wall, but other than that, it is a good read.

Who the Hell do You Think we Are? by Talos

  • Recommended by SAMAS
  • Crossover with: Tengen Toppa Gurren Lagann
  • Status: Dead
  • Synopsis: The Dai-Gurren gang perhaps should have taken a closer look around their galaxy, because their world has found it's way into the Eye of Terror. But it's okay, since Kamina and Lordgenome have a plan.
    • Proofreading doesn't seem to be a thing the author has heard of. Sure, kick reason to the curb. But be warned that spelling, punctuation, and sentence structure/pacing have also been give the boot, and that might get in the way of enjoying the story.

Jar Jar and Warhammer, 40,000

  • Recommended by Slaanesh Is Sexxxy
  • Crossover with: Star Wars
  • Status: Dead
  • Synopsis: "What follows next has been drawn from transcripts and reports from the sides fighting on that world, although naturally it must be taken into account the mental affects this untold abomination had on those interviewed. I truly pray to the God Emperor in his eternal wisdom that such an event never repeat itself."
  • Comments: I never thought I'd root for Jar Jar over anything. Just read it yourselves.

The God of Death By Tyrant of the East.

  • Recommended by: Cosmic-Behemoth
  • Crossover with: World of Warcraft
  • Status: Dead
  • Synopsis A Space Marine from the Death Spectres Chapter is caught in the warp and is transported to the planet of Azeroth, and is caught up in a whirlwind of Chaos infestation, Scourge, and wholly unwanted Xenos infatuation. The blood flies and the bodies hit the floor. In the works, very long, and has at least two sequels already planned.
  • Now has its own page.
  • Probably a dead fic, hasn't been updated since 2011.

  • Comments: If you ever wanted to see a crossover where things get worse for both ends of the crossover, then this is the one. And the top thing on this list? BLOODTHIRSTER SAYAKA.

Property Damage By Kagaseo

  • Recommended by: Metal King 1417, Captain Silver
  • Crossover with: Fate/stay night
  • Status: Dead (last update September 2014)
  • Synopsis: Zelretch, bored to death, decides to cause mischief. As a result, the Grail calls upon seven of the most overpowered Servants the Throne of Heroes has in store. In the not so grim darkness of the current present… there can only be property damage. And crazy aliens.
  • Comments: The masters of the fifth grail war summon servants from Warhammer 40000. While not very far along, the interactions between characters are pure gold, especially between Lancer (Trazyn the Infinite) and Gilgamesh.

The Swarm of War by VexMaster

  • Recommended by: Omeganian, Mr Kaboom
  • Crossover with: Starcraft
  • Status: Dead (last updated August 2017)
  • Synopsis: A nerd has reincarnated as a Zerg Larva... and now he has been dropped into the Warhammer 40K. There is no time for peace. No Respite. No forgiveness. There is only WAR and the Swarm!
  • Comments: The spelling is a bit off sometimes, but the idea is an interesting one. It took 40 chapters just to get to the point where the Zerg can expand beyond a single planet. Now it's nearly 80 chapters, and they, like any respectable Warhammer 40K faction, are fighting on a thousand fronts. Overpowered. Improved. But then, they have to be. After all, there is only war...

  • Synopsis: Fusion Fic. The Wizarding World is devastated when Harry Potter disappears from his relatives' house in mysterious circumstances during the summer after his first year at Hogwarts School of Witchcraft and Wizardry. Desperate to have their boy-hero back no matter what they really should have heeded the Muggle saying "be careful what you wish for".
  • Comments: This series is absolutely hilarious while at the same time managing to incorporate the things about Warhammer that are quite... unsettling.

The God Empress of Ponykind by Iowaforever

  • Recommended by mannowdog

  • Status: Complete, with a sequel.
  • Synopsis: Fusion Fic. When the God-Emperor is restored during a Chaos attack on the Imperial Palace, He was cast into the Warp and spat out in a different universe, having been turned into a (female) pony...Princess Celestia. Unable to return to the Imperium, the newly transformed Emperor begins to build a new empire from the ground up, but has to deal with old and new foes.
  • Comments: Yes, it's the inevitable MLP fic. However, the author is very good at adapting elements from Warhammer to Equestria (There's a gore tag for a reason), as well as Canon Welding parts from MLP.

  • Status: Ongoing
  • Synopsis: As the 41st millennium draws to a close, Yang Xiao Long appears in the Imperium of Man, lost and bereaving the death of her sister. Unending war and horrors the likes of which she's never known await...
  • Comments: This is a great story. In this Tropers considered opinion that was formed after binging the heck out of RWBY and being a longtime fan of Warhammer RedRumSprinkles gives a great look at the brutality of the forty-first millennium's battle fields while staying true to Yang's characterization.

A New Inquisition by Atilas

  • Recommended by: Golden Alex
  • Crossed with: The Legend of Korra
  • Pairings: Brief Asami/Mako, brief Korra/Mako, plus minor OC/OC.
  • Synopsis: Following an encounter with a Deamonhost and a rushed teleportation, Inquisitor Kali find herself on a new world. Now stranded, away from the Imperium and in a place ignorant of the dangers of the Warp, what will she do? Rebuild the Inquisition would be a good start.
  • Status: Dead (last updated February 2017)
  • Comments: A VERY good fic which explores what happens if the horrors of the 40K universe met the Korra era Avatar World. Equal moments depressing as characters become more and more jaded over the course of the fic, and awesome in the way that only 40K can be. English is not the authors first language, so it sometimes reads a little oddly, but it doesn't detract from the fic.

Silly but Killy

  • Recommended by: Dvorak
  • Crossed with: Mass Effect
  • Status: Dead as of April 23rd, 2016
  • Synopsis: Imagine if the Systems Alliance were replaced with an Ork Waaagh. Specifically, Kommando nob Sheppurt and his mob of boyz, and the hapless aliens he collects.
  • Notes: Pure crack. Not a single chapter — or paragraph — goes by without something to laugh about. A shame it's dying, it is absolutely hilarious.

Armed to the Teeth by Boyd the Reaver

  • Recommended by Avalon 2163
  • Crossover with: Fire Emblem.
  • Pairings: Boyd/Mist
  • Status: Complete
  • Sypnosis: After Mist's unexpected demise during the final battle with Ashera, Boyd traverses through the outrealms to find a way to resurrect her. He'd end up finding that answer in the grim, dark future with a certain Blood God willing to have an arm wrestling contest with him. Unfortunately for Khorne, Boyd's soul proves to be more trouble than he's worth.
  • Comments: Scamming Cthulhu at it's finest. The jokes are great, the characterization is spot-on, and the whole fanfic is one giant love letter to both franchises as well as a clear nod to Creed. It's a damn shame the author is barely known, he's very creative, so I put in a recommendation for him. A great, funny and even heartwarming one-shot if you seek to escape the grimdark nature of Warhammer 40K.

  • Synopsis: Remnant is a dangerous world. Humanity is hemmed into small pockets of hope, pressed inwards by the encroaching horrors that lurk in the dark. Yet all a Warpsmith of the 20th legion sees are opportunities.

The planet Remnant; specifically the kingdom of Vale several months prior to the 40th Vytal festival. Eliphas is without his cursed wargear and the various daemonic blessings he gathered during the dark crusade, but his greatest weapon still remains to him; the limitless charisma of a Dark Apostle of the Word Bearers. Remnant will never know what hit it."

Eldarstuck by Mental Omega

  • Recommended by: Varaxar,
  • Crossover with Homestuck
  • Status: Ongoing
  • Synopsis: What do you get when you cross over the series that gave us the term "Grim darkness of the far future" with Homestuck? You get Eldarstuck! In this quest, the players follow a twelve player session said to be the scene of a struggle of not just the twelve Eldar children, but the orderly, rules bound nature of Paradox Space and the chaotic "will to power" nature of the Warhammer metaverse. With quick updates, snappy writing, stand out characters, and an author who clearly deeply adores both Warhammer 40,000 and Homestuck, this is a quest that you wouldn't want to miss.
  • Pairings: None yet
  • Tags: Quest, Original Characters
  • Comments: The story is still early into its writing, but Mental Omega has been good about updating very frequently so far and as with all quests; the more contributors the better. You do need to sign up for sufficient velocity if you want to participate in the voting process and not just read though.

  • Synopsis: With Earth finally safe, it seems that the DOOM Slayer finally has his time to rest. Unfortunately for him, messing with things like cosmic order and other such matters attracts the attention of certain powerful entities. One such entities is very interested in his abilities to change fate.
  • Comments: The story is set right after the events of Eternal (and ignores the events of The Ancient Gods) on the Doom side and before the Fall of Cadia on the 40K side. Despite the slow pacing at times, the action is amazing, and the interaction between Imperial forces and the Slayer (and allies) is great.

An Investigation into the Primarch Sigmar's Homeworld by Some Scribe

  • Recommended by: MrTerrorist
  • Crossover with Warhammer Fantasy
  • Status: Ongoing
  • Synopsis: What happens when some naïve Great Crusade-era Space Marines land on a world where gods are real, medieval soldiers can kill Bloodthirsters, and everything is utterly tainted by the Warp? Hilarity, horror, and lots of stupid deaths, that's what.
  • Comments: In this AU crossover fanfic with Warhammer Fantasy set during the Great Crusades, Sigmar is the Second Primarch but is considered a failure by almost everyone in the Imperium leadership due to uniting his home planet under his rule and failing to spread the Imperial Truth to the populace. With the exception of Horus and Leman, the other Primarchs and their Legions see Sigmar as an embarrassment. When an Imperial Survey group which includes a detachment of Space Marines from the Space Wolves, Thousand Sons and Dark Angels heads to Sigmar's home planet to learn more about his world, they soon learn that Sigmar may not be the failure they they think he is and his world much more dangerous than they thought.

Soon he will find himself fighting a familiar enemy and in order to save mankind he will need to cast aside old prejudices.
  • Comments: If you're not into Thou Shall Not Kill and into Pragmatic Hero, this is a Prime cut for you. While a lot of the Justice League can't see past his age, the younger heroes group do eventually appreciates his approaches and accepting him. Expect a lot of Jerkass Has a Point and Combat Pragmatism.

  • Recommended by: VictorioMWolff-Haddock
  • Crossover with: Valkyria Chronicles
  • Status: Ongoing
  • Synopsis: The Fall of Cadia did much to the morale of the Imperium. As the Cicatrix Maledictum and its recurring Warp-Storms opened, one such storm caught, at the whim of a higher being, a Regiment of almost 5,000 soldiers more young than most you'd see in the Guard, shipping them to a new world, with new threats and, perhaps, a chance at Retribution.
  • Comments: After the destruction of their planet, a Cadian Regiment known as "The First Youth" were stranded in Europa, and joined forces with Gallian after seeing (local) Imperial forces firing at civilians. Besides the "False Imperials", the allying group must face religious and cultural clash and the possibility that the Cadians may not be the only one from their galaxy that has arrived here...

Turns out, Issei is not alone as all 18 of The Emperor's female Primarchs are also stranded there. Issei then gets Adaptational Superpower Change, and thanks to him, Konrad and Angron become better.

Feral World Religon

  • Recommended by USA Bobcat, Eversor, Baron Praxis
  • Status: Complete
  • Synopsis: Two Sisters are stuck on a Feral World, and learn of their interesting spin on the history of the Imperium, specifically, the Horus Heresy.
  • Comments: Short, but funny, the punchline is that one (and only one) of the Primarchs is portrayed as he really is. Have fun trying to guess which it is! This piece is well worth the quick five minutes you will spend reading it, and is a true example of how good /tg/ can be at times.

BrightHammer 40k

  • Recommended by Whakamol, Icarael, Mike Rosoft
  • Trope Page: Brighthammer 40,000
  • Synopsis: Does regular Warhammer and its incessant Grimdark have you down? Then try out the Noble Brightness of Brighthammer, where the future holds only High Adventure!
  • Comments: A mirror setting of regular Warhammer 40k, with a goateed Emperor and Fum'aan Shu'u, the rogue Tau mad scientist. There are actually two versions of Brighthammer; the one linked above, which is more satire, and BrightHammer 2.0, which is more serious and discussed here.


  • Recommended by FLCNPNCH, Chaos Undecided, Extraintrovert, Captain Chaos, Icarael
  • Synopsis: Kharn the Betrayer is a famous Chaos Space Marine who revels in bloodshed. All bloodshed. Exactly who is doing the shedding, he doesn't care so much, and thusly has a wholly deserved reputation as a teamkilling f* cktard. Despite this, he's actually a pretty fun guy.
  • Comments: Yeah, Kharn is made of win and good.

  • Recommended by FLCNPNCH, Chaos Undecided, Captain Chaos
  • Synopsis: Various Space Marine chapters formed in the unholy, all-consuming black void that is 4chan. Includes the ever popular Angry Marines.
    • Some of the more "serious" fan chapters like the Emperor's Nightmare have some pretty awesome writings behind them as well.
    • Generally, there are two types of marine chapters on 1d4chan: the first is the more "Silly" which are usually one chapter with a single quality taken to ridiculous extremes, such as the Angry Marines (their trait being anger) or the Reasonable Marines (their trait being that they're actually sane in the 40k universe). The other types are the "Serious" chapters, which use actual gameplay rules to create chapters that are more compliant with the universe as a whole, and can lead in interesting directions. The Desert Fangs (serious counterpart to the Angry Marines) and the Knights Inductor (counterpart to the Reasonable Marines) are quite well thought out and have fascinating stories written about them.

The Consortium by 4chan's /tg/

  • Recommended by FLCNPNCH, Chaos Undecided
  • Synopsis: Not quite a Warhammer 40k fic, it's closer to a fic about the 40k fandom that exists in 4chan, mainly regarding Love Can Bloom.
  • Comments: Interesting. Veeeery interesting. As with just about everything to do with 4chan, some parts may or may not be NSFW.


  • Recommended by FLCNPNCH, Chaos Undecided, Extraintrovert
  • Synopsis: K59 is an otherwise unnamed Commissar imprisoned by the Inquisition for executing too many of his own men, the story relating the events that led up to K59's imprisonment by an Inquisitor.
  • Comments: An unconscionable monster by our standards, but in a world of grimdark he is a surprising beacon of purity and determination against the horrors of the universe. It's short, so decide for yourselves.

The Ever Virgin

Machas Vacation

  • Recommended by FLCNPNCH
  • Synopsis: More Macha!
  • Comments: More NSFW and funny!

Tiny Hammer

  • Recommended by FLCNPNCH, Chaos Undecided, Baron Praxis
  • Synopsis: All the forces of the 41st Millennium descend onto modern day Earth. Except they are only as large as their miniatures depict them to be. Space Marines are an inch tall, Monoliths barely come up to your ankle, and Imperator Titans are the size of a van.
  • Comments: Funny stuff.

Looted Emperor

  • Recommended by FLCNPNCH, Chaos Undecided, Baron Praxis
  • Synopsis: Orks loot the Empra. Hilarity Ensues.
  • Comments: It has Orks. What more do you want?

GRIMDARK Macha(link is dead, so here is a link to the archived version).

  • Recommended by FLCNPNCH
  • Synopsis: Macha, beloved of /tg/, falls prey to the GRIMDARK of the 41st millenium, and kills her sister Taldeer in cold blood. Alternate (Good?) ending leads to sistercest, and finally we see what happens when LIIVI finally catches up to his lover's killer...
  • Comments: Direct link to archived thread on sup/tg/. Cannot be held responsible for any heresies that you may encounter. Also, the story's damn good.

Inquisitor Malius

  • Recommended by FLCNPNCH
  • Synopsis: An Inquisitor leads an assault against a small Chaos cult with a Baneblade (wait what?).
  • Comments: Shock ending makes the entire thing win. Link is to sup/tg/, so lot's of NSFW.

Straying From the Path, Part II Part III

  • Recommended by FLCNPNCH
  • Synopsis: Macha is captured by the Imperium, and promptly attempts to seduce a Commissar.
  • Comments: Poor, poor Macha. Link is to sup/tg/, so inevitably some parts are NSFW.

Warhammer 40k Group

  • Recommended by FLCNPNCH, Medinoc
  • Synopsis: The entire 40k universe is actually nothing more then a long running tabletop game and all the gods are the players of their respective races/armies. Anything, and I mean anything, about the Emperor invokes MANLY TEARS.
  • Comments: Link is to sup/tg/, so risk of NSFW language is high. Pictures are safe, barring "943419_20071025_screen006.jpg" which straddles the line.

Guardsman Eli

  • Recommended by aRIS
  • Synopsis: Guardsman Eli tells why he is no longer a good man.
  • Comments: Began as a post wondering why people still think of the Guardsmen as protagonists, question is answered by Gemini starting at 5593915. Link is from sup/tg/ and hence NSFW. Mildly touching.

Gav and Bob

  • Recommended by Wizard Joni, Extraintrovert, DealsWithFate3
  • Synopsis: Gav is an Ogryn. Bob is also an Ogryn. Gav like Bob. Bob is Gav's best friend. Gav and Bob fight enemies of the Emperah, like greenskins and bugs and the bad men that stopped loving the Emperah. Gav hates them the most.
  • Comments: Crying because of an Ogryn is hardly dignified, but in this story it is inevitable. Gav is an Iron Woobie of the most spectacular sort.


  • Recommended by FLCNPNCH, Chaos Undecided, Extraintrovert, Captain Chaos, Icarael, Baron Praxis
  • Synopsis: Orks decide to join some of the other factions. What?
  • Comments: Orks. Ergo, win.


  • Recommended by Extraintrovert, Icarael
  • Synopsis: Slaanesh, even after 10,000 years, is still an outsider when dealing with the other Chaos Gods. In an attempt to get closer to them, she asks about the person she has heard them mention occasionally, and is told a story about their old friend.
  • Comments: Holy crap. I don't even know where to begin with this one. It is based on no official material whatsoever, but is so damn plausible and adds an extra layer to the grimdark of the galaxy that I never even imagined. It's rather short, so read and decide for yourselves.

The Guy Who Cried Grendel

  • Recommended by J Bridge, Medinoc, Eversor
  • Trope Page: The Guy Who Cried Grendel
  • Synopsis: A recounting of a Dark Heresy campaign, and the luckiest bastard to ever roll a die.
  • Comments: Tabletop RPGs are ripe for awesome and unlikely stories, and this is one of the best I've seen. Grendel is a fat librarian with no skills whatsoever, but somehow manages to do things not even Space Marines are capable of. (That's no exaggeration: at one point he manages to defeat a Chaos Space Marine that had managed to take down an entire company of Space Wolves.)
  • One of the later splat books had a background piece of fluff featuring an investigation into the fic's events, more or less making it canon.

Daria 40k: Is It The Grim Darkness Of The Far Future, Yet? by RX-87 (crossover with Daria, natch).

  • Recommended by fhtagn.
  • Synopsis: The cast of Daria (and some old friends from Our Heroine's past) take on the roles of Imperial and Chaos forces as the battle for the fate of Planet Lawndale rages and Hilarity Ensues.
  • Comments: Utterly hilarious, though it does require a working knowledge of both the 40k and MTV Animation-verses to really appreciate. The characterizations are spot-on almost to a fault (Jane's libido does veer uncomfortably close to OOC (and Fluff-inaccuracy) once or twice, but it does get an amusing justification towards the end).

Abaddon Quest

Tales of the Emperasque, by Someone Else (link)

  • Recommended by Medinoc, Willbyr, Baron Praxis
  • Description: As the Imperium is falling apart at the seams, the Emprah tries a desperate maneuver and comes back possessing the body of a Tarrasque. Awesome (and some stern talking-to) ensues. The fic incorporates a bunch of other /tg/ Fanon, such as LIIVI or the Blood Ravens' kleptomania.
  • Comments: One of those stories that works best when you don't take it all that seriously, but the occasions when it does get into genuine character bits, it handles them surprisingly well. Lots of Alternate Character Interpretation going on, but it all just contributes to make the story better, so one can hardly complain too much.


  • Recommended by: Icarael
  • Synopsis: A short vignette about Ork Warboss Ghazghkull Mag Uruk Thraka and the banner waver he once had by his side.
  • Comments: Although short, this fiction shows that the Orks, like any other race, are capable of feeling loss. Manly Tears are perfectly excusable when reading this.

Heretical Love


  • Recommended by ilniaj
  • Synopsis: Two individuals end up trapped beneath rubble.
  • Comments: A short story that a reader can go through in about two minutes. Decent characterization is done in such a short time and a Heartwarming Moment is at the end.

Love and Krieg Spinoffs

  • Recommended by Deals With Fate 3
  • Synopsis: Inspired by the first stories in Love and Krieg other writers took it upon themselves to create side stories about Krieger Female Model 68b #6345's sisters and their own romantic adventures. Notable is Krieger Female Model 68b #6346 who gets involved with another nameless civilian in a similar manner to the original stories and Krieger Female model 68c #6345 who ends up with a Commissar in the regiment. And after that... Things leave the realm of romantic comedy and enter the province of sheer noblebright fuckawesome. And Win. And now back to romantic comedy.
  • Comments: Terranis Holds. Forever. Absolutely brilliant. Reading Love and Krieg beforehand isn't necessary, but certainly adds to the full experience, showing you even more depth to the Death Korps of Krieg.

The Commissar and His Maid

  • Recommended by Deals With Fate 3
  • Synopsis: A spin off of a spin off of Love and Krieg detailing the further adventures and awkward romance between The Commissar and Female Krieger Model 68C #6345. Also contains some nightmare fuel about the scribe servitor who takes down The Commissar's correspondence.

Grimdark Songwriting

  • Recommended by Deals With Fate 4
  • Synopsis: Observing some striking correlations between the songs found in children's movies and the 40K universe, people on /tg/ sometimes adapt these songs to bring out their true grimdark potential.

Confessions of a Wayward Son

  • Recommended by ilniaj
  • Synopsis: A story about a Thousand Sons sorcerer that controls a small army of 300 Rubric marines and his experiences from the beginning of the Emperor banning sorcery to his actions after the Horus Heresy.

All Guardsmen Party by Shoggy (1d4chan Link)

  • Status: Ongoing
  • Recommended by WildGoose, tatertots
  • Synopsis: An After-Action Report by Shoggy, All Guardsmen Party is the tale of a group of guardsmen who're recruited into an Inquisitorial party, showing just how well a group of slightly competent Guardsmen deal with multiple Dark Heresy campaigns, in manners both awesome and funny. Also, the way their GM sets up their backstory has to be seen to be believed. Requires surprisingly little Warhammer knowledge to be enjoyable.

Waiting for Godot: 40k edition

  • Status: Complete
  • Recommended by AnonFangeekGirl
  • Synopsis: In which a disabled Necron Lord is trapped in a cave with an equally disabled Imperial Fists dreadnought. After trading insults and empty threats for a few days, the two eventually begin to have actual conversations in which they tell the histories of their races while waiting to see whose army reaches the pair first. Now with two new endings from the original author!

Return of the Primarchs

  • Status: Ongoing
  • Recommended by AnonFangeekGirl
  • Synopsis: What if, in a giant act of just as planned, Malal, Cegorach, and The God-Emperor of Mankind, in concert with all of the other anti-big 4 chaos gods engineered the return of the Primarchs, from a point in time early enough in the crusade that they all don't hate each other, and a few other changes, notably the removal of Angron's Butcher's Nails and the curing of Curze's madness. Oh, and they have at least some part of their legions and support staff, so Mechanicum, remembrancers, all that.The result is a setting based on badassery, noblebright, and manly tears.
  • If nothing else, read for the emotional moments between the Primarchs as they sort out their issues between themselves and with their main-universe counterparts.

Nobledark Imperium

  • Status: Ongoing
  • Trope Page: Nobledark Imperium
  • Recommended by Hello 101
  • Synopsis: The Warhammer universe reimagined a lot as a Nobledark setting instead of a Grimdark setting. By the end of M41, the 13th Black Crusade, led by Lady Malys of the Crone/Chaos Eldar, has begun, alongside the Dark Eldar, Chaos, and the Chaos Orks, with Ghazgkull planning to rebel very soon, the Tyranids arriving really en masse, the Necrons almost all having awoken, and the Imperium consisting of humanity, the Craftworld/Exodite eldar, the demiurg, tau, and countless other species.

Marcius Flavius

  • Recommended by Baron Praxis
  • Synopsis: Marcius Flavius, Battle-Brother of the Imperial Fists, was the first space marine assigned to a Federation starship in the historic Federation-Imperium officer exchange program. In his place went Commander Riker of the Enterprise to the Imperial Fists' fortress-ship, the Phalanx.

Fallen from Grace

  • Recommended by Baron Praxis
  • Synopsis: A Dark Eldar falls in love with a human farmer while hiding on an agri-world.


  • Recommended by Baron Praxis

False Immortality

  • Recommended by Baron Praxis

Half-Life 40k

Heresy from the Emperor's point of view

  • Recommended by Baron Praxis
  • Synopsis: An examination of the Horus Heresy and the evends leading up to it from the point of view of an ancient being that only wants the best for humanity.

Boone Quest (story-only version also available)

  • Recommended by MBG159
  • Status: Nearly complete, currently wrapping up amidst Schedule Slip.
  • Synopsis: A Quest focusing on low-grade psyker and Commissarial aide Alice Boone, as she attempts to reunite a ragtag Ordo Xenos unit, take down a heretical organization, and find true love.
  • Comments: Part of the overall "The Ragged Edges" set of stories - though the quality of these stories can be up-and-down, Boone Quest is easily an up, featuring decent puzzles, well-done (if sometimes excessive) Shout Outs, creative characterization and humor, and some earnest and satisfying storytelling. Notable for being completely illustrated, a vanishing rarity for a Quest of its size and complexity.

Love Can Bloom, Imber, Core of Brutality, Meet the Ulthran, Full Melta Panic! and Lofn by 4chan

  • Recommended by FLCNPNCH, Radioactive Zombie, and Lord Of The Sword
  • Status: Dead
  • Synopsis: Love Can Bloom is the title of one of the most well-loved pieces of writefaggotry ever to grace /tg/. Once upon a time, there was a drawfag named Miko. She made a comic about a Vindicare assassin falling in love with Taldeer from Dawn of War: Dark Crusade and Dawn of War: Winter Assault. There was much nerd rage. Then, somebody started writing a fanfic for this fan picture. There was a mixture of nerd rage and delight. Also of note are the MANY offshoots that Love Can Bloom has spawned. Ranging from Core of Brutality, a story about the Eversor hunting the duo, to the continuation in Imber, to Lofn who is just d'aww.
  • Comments: Really, really good. Note that many of the pictures at the bottom of the pages are NSFW, like so many things on 1d4chan. Also, unfinished, due to the author stopping from stress partway through.

Love and Krieg by 4chan's /tg/

  • Recommended by Truckman, Deals With Fate 3, necrolectric
  • Status: Complete
  • Trope Page: Love and Krieg
  • Synopsis: Love and Krieg is a collection of short vignettes born from the crazy minds and sappy hearts of a bunch of /tg/ anons tickled by the idea of a Krieger girlfriend. The stories detail the sometimes humorous, often heartwarming events in the relationship between an unnamed, well-meaning Imperial civilian and Krieger Female Model 68b #6345. Each story loosely constituted a date or some outing, most of them tying together without any strict sense of chronology. The end result was something magical, evoking a sense of idyllic innocence rarely found in the grim darkness of the 41st millennium.
  • Comments: A Heartwarming Moment for the Warhammer 40,000 setting, which can always use a few more of those. Not sure what else there is to comment on, the stories speak for themselves.
    • A lighthearted story that has some fun, but doesn't offend purists of the setting at the same time.
    • The spinoffs of this story are incredible as well. Terranis Holds!
    • Starts out with hilarious romantic comedy, but I was actually crying by the time I finished. Any fan of 40k needs to read this fic.

Behind the Mask by Osmium Anon

  • Recommended by tatertots
  • Status: Complete
  • Synopsis: A Space Marine and an Eldar are marooned on a tyranid infested world, having to rely on one another in order to survive and, hopefully, escape. Enemies to cautious allies to lovers to ???
  • Comments:Well written and surprisingly touching, also very much NSFW
