Funny request incoming! How would the Primarchs react to hearing one of their own Astartes say something unbelievably stupid within earshot when asked about where do babies come from by another younger Astartes?
Like when you hear someone say something so impossibly wrong and stupid, but with such confidence, that it leaves you stun locked for a moment
(I don't know how to name this🤣)
“Brother… where do babies come from?” A very young astartes newly enlisted and still with that tragic ‘I have never had a normal childhood and I think nutrition paste is cuisine’ energy asks.
An older astartes with the confidence of a man who has conquered worlds but never attended basic biology replies something so wrong that reality itself pauses.
Lion El’Jonson
“Babies are produced when a fortress monastery’s machine spirit approves a compatible pair of skull measurements.”
The Lion freezes and everyone in the room feels the temperature drop by seven degrees. He turns his head very slowly and gives the astartes exactly three seconds to realize his mistake.
“Explain.”
The Astartes tries but it only gets worse. The Lion places one hand over his face and is privately wondering whether the Emperor included basic reproductive knowledge in the great crusade educational package or if this was yet another one of his tbd details.
“You will attend a remedial lecture.” The Lion concludes. The Dark Angels later classify the incident, the younger astartes is told the truth, the older one is assigned to archival duty until shame becomes part of his personality.
Fulgrim
“Babies are made when two people both become aesthetically complete enough that a cherub manifests.”
Fulgrim hears that and for one brief second his face is completely blank in absolute psychic disconnection. “My son, that was the ugliest sentence ever spoken in my presence.” He begins a lecture that starts with biology, becomes art theory, detours into poetry, condemns ignorance as a crime against beauty and ends with the entire squad being enrolled in Foundations of Human Life, Courtship and Not Embarrassing Your Primarch in Public.
The younger Astartes leaves informed while the older one leaves emotionally exfoliated.
Perturabo
“Babies are assembled in batches like munitions, civilians simply lack quality control.”
Perturabo stops walking and turns around. “Repeat that.” The Astartes repeats and Perturabo just stares with the face of a man discovering a structural flaw in a bridge he personally designed.
“You believe the human species is manufactured like artillery shells?”
The Astartes hesitates. “...With less reliability, my lord.”
Perturabo closes his eyes and you can hear one of his remaining hopes die. He gives the most brutally efficient reproductive biology lesson in Imperial history complete with diagrams, mechanical analogies and insults.
“If I ever hear you explain biology through siege logistics again I will assign you to inventory every bolt in the fleet.” The primarch concludes. The younger Astartes now understands.
Jaghatai
“Babies come from speed, when two people ride fast enough beneath the open sky, the wind chooses.”
Jaghatai hears this and laughs immediately. “That is the stupidest thing I have heard this century.” The older Astartes looks embarrassed and the younger one looks confused. “Listen, life is stranger and far less aerodynamic than that.”
He explains it plainly and with surprising gentleness but keeps laughing every time he remembers ‘the wind chooses’. For the next several months the entire brotherhood uses the phrase ‘the wind chooses’ whenever someone announces a birth on a compliant world.
Russ
“Babies come from drinking enough mead and winning a wrestling match against fate.”
Russ nods slowly and for one horrifying moment everyone thinks he agrees until he speaks.
“That is wrong, but not as wrong as it should be.” He walks over and claps the older warrior's back hard enough to almost crack the armor. “You’ve got the spirit, pup, but you’ve missed several important steps.”
“Does wrestling occur?” The younger astartes asks.
Russ thinks about it. “Sometimes.”
A wolf priest immediately materialize from nowhere. “My lord, please allow me.”
Russ is removed from the conversation before he can make it worse. Later he hosts a feast where he tells a long extremely inappropriate Fenrisian version of the facts of life involving wolves, storms, endurance and respecting women because otherwise they will kill you and deserve to. The younger Astartes learns something but nobody is sure of what exactly.
Dorn
“Babies are grown when a household reaches sufficient structural stability.”
Dorn hears that and looks at the astartes with the expression of a fortress wall being disappointed.
“No.”
“No, my lord?” The Astartes straightens.
“No.”
The younger astartes waits for more and Dorn realizes with visible pain that more is required so he explains reproduction with the exact tone he would use to describe masonry, it’s terrifyingly practical with out unembellished or euphemisms despite the entire squad wishing there had been euphemisms.
“Don't invent civic infrastructure theories about childbirth again.”
“Yes, my lord.”
“Also households do benefit from stability.” Dorn adds. “But that is unrelated to conception.”
Konrad Curze
“Babies come from nightmares, if enough people are afraid in one place a small human appears to continue the suffering.”
Curze hears that and makes a weird sound that may be laughter.
“Wrong.” He leans in. “But thematically… interesting.”
The younger Astartes is now more confused and significantly more traumatized, Sevatar who has been standing nearby ends up explaining the basics in the driest possible tone while Curze occasionally interrupts from the shadows with comments like “and then they are born screaming.”
Sanguinius
“Babies are made when two souls love each other so much that the Emperor sends them a tiny servant.”
Sanguinius hears this and looks physically pained. “My son, that is… very sweet.” He approaches gently and places a hand on his shoulder. “And almost entirely incorrect. Love can be involved, often, one hopes it is but there is also nature at work.”
He explains it kindly and with enough delicacy that nobody feels mocked and with enough accuracy that the sanguinary priests silently nod in approval. The younger Astartes understands, the older one is embarrassed but not crushed. Sanguinius later asks the Chaplains whether perhaps the legion’s education has been a little too focused on swordsmanship and blood rites.
Ferrus
“Babies are manufactured through inferior organic replication, the flesh copies itself because it lacks proper modularity.”
Ferrus stops hammering and slowly sets down the tool. “You are technically approaching a concept and somehow still failing. The flesh is weak, yes, but it isn’t a forge template.” He explains reproduction in blunt practical terms using enough biological detail to be correct and enough mechanical comparison to keep them from panicking.
“You won’t teach again until you understand the difference between organic process and manufacturing.”
“Yes, father.”
“And don't call infants unfinished components, civilians dislike that.”
The Iron Hands quietly amend several educational scrolls.
Angron
“Babies come from blood, enough blood spills and eventually life crawls out of it.”
Angron hears and everything stops, the older Astartes suddenly realizes he has chosen the worst possible primarch to say this near.
“No.” Angron turns, jaw tight. “That is what monsters tell themselves when they only know how to make corpses. People are born from bodies, women and from pain, yes, but not that kind, it isn’t a slaughter. Don’t make life sound like one of our battlefields.” Then he walks away before anyone can see too much on his face.
Guilliman
“Babies are issued by local family governance after a successful marriage petition and population sustainability review.”
Guilliman hears this, his face is calm but his soul nearly left his body.
“...Issued?”
“Yes, my lord, by civic authority.”
Guilliman blinks very slowly. “I have failed you.”
“No, my lord!” The Astartes immediately panics.
“Yes, clearly. Somewhere in your education a catastrophic omission occurred and now you believe municipal paperwork is reproductive.”
“It is not?” The younger astartes whispers and Guilliman visibly ages.
He organizes an emergency curriculum reform within six hours. The original Astartes isn’t punished but he is cited anonymously in the introduction as ‘a demonstrated educational failure.’
Mortarion
“Babies grow from spores in damp places, that’s why civilians keep their houses warm.”
Mortarion hears that and for one long moment he stays in silence.
“No.”
The Astartes waits.
“And never say that again.” Mortarion continues.
“But my lord, don’t they grow?”
Mortarion looks like he has been stabbed by stupidity. “Not like fungus.”
“But there is an incubation-”
“Stop helping.”
He gives a short and factual explanation stripped of romance, mystery and any possible joy, he makes normal biology sound like a diagnosis.
“Life is already unpleasant, don’t make it idiotic.” The Death Guard accept this as inspirational wisdom.
Magnus the Red
“Babies are formed when two psychic signatures resonate and attract a soul fragment from the immaterium into a prepared vessel.”
Magnus slowly lowers his book, the statement is wrong but in a way that has wandered too close to several metaphysical arguments Magnus would absolutely like to have.
“No, not precisely.”
Magnus gives a lecture about reproductive biology, genetics, psychic resonance and the philosophical question of when consciousness enters matter. The younger Astartes looks increasingly haunted, the older one tries to take notes and gives up after the phrase ‘ontological threshold’.
After two hours, Magnus concludes. “So, in summary, you were wrong.”
“Where do babies come from then?”
Magnus smiles. “Let us begin again.”
Horus
“Babies happen when a great leader inspires a population hard enough.”
Horus hears this and nearly chokes on his drink.
“What?”
“Because morale increases birth rates, my lord.” The Astartes smiles proudly. This is the kind of wrong that has a tiny piece of political truth inside it, making it vastly more annoying.
Horus laughs first until he sees that the younger astartes genuinely believes it. “Oh. You’re serious.” He puts an arm around both of them like a beloved warlord about to deliver the most uncomfortable fireside chat of their lives. “Right. We are fixing this before you embarrass me in front of a remembrancer.” Horus explains it plainly, with charisma, humor and exactly enough vulgarity that they will remember it forever, by the end the squad is informed and slightly traumatized.
Lorgar
“Babies are granted when faith pleases the divine and a household becomes worthy of receiving a soul.”
Lorgar hears this and his eyes shine, that answer is wrong but it’s spiritually marketable. He interrupts only because he remembered he is supposed to be responsible. “My son… there is beauty in what you said but we mustn’t confuse metaphor with mechanism.” He then gives a lecture that is half biology and half sermon, the younger Astartes leaves understanding the basic reproductive process and also believing childbirth is a sacred ritual written in flesh. The older one is gently praised for seeking meaning but corrected for being factually disastrous.
Vulkan
“Babies are made when a family loves each other so much that they build one together, like a small forge project.”
Vulkan hears that and his face does the thing where he is trying very hard not to laugh because the answer is wrong but also extremely adorable.
“That isn’t how it works, my son, but I understand why you said it.”
He explains with warmth, patience and absolutely no shame. The younger Astartes asks many questions and Vulkan answers all of them.
“So they aren’t built?” The older Astartes asks.
Vulkan pats his shoulder. “No but they are raised, that’s the building part.”
Corvus Corax
“Babies emerge from silence when loneliness becomes too heavy.”
Corax hears this from the shadows and remains silent for so long that both Astartes assume they are safe until a voice comes from behind them.
“That was poetry pretending to be information, don’t do that.” Corax steps forward and the older Astartes almost jumps out of his armor.
“But it sounded meaningful, my lord.” The younger Astartes says.
Corax sighs and explains the truth quietly and directly, though with a melancholy edge that makes the whole thing sound like a tragic folk story.
“Loneliness may lead people to seek love and love may lead to children but babies don’t condense out of sorrow… Usually.”
The Raven Guard are left unsure whether that final part was a joke.
Alpharius Omegon
“Babies are created when two adults exchange classified genetic intelligence through a covert biological operation.”
Alpharius is nearby or Omegon or both.
“That isn’t entirely inaccurate.” He says
“It is also a terrible explanation.” The other twin speaks as he appears from absolutely nowhere.
“Was I wrong?” The older Astartes looks between them.
“Yes.”
“No.”
“Operationally.”
“Pedagogically.”
The younger Astartes is now more confused than before. The twins proceed to explain reproduction using intelligence terminology, espionage metaphors, at least three false examples, one true example disguised as a lie and a diagram that self-destructs after viewing.
“So… where do babies come from?” The younger Astartes asks at the end.
“Ask your apothecary.” Alpharius smiles.
“But don’t trust his first answer.” Omegon adds.
my favorite genre of fictional character is like "i am terrifying to almost everyone, i'm very good at killing, i can endure anything, i've become exceptionally good at playing into my reputation, and if you try to give me positive social interaction i will react with confusion and cower in a corner like an abused animal. and i may try to shoot you. but there is also a chance i may imprint on you like a feral dog receiving its first loving touch! good luck."
Lion El’Jonson
The marine asks and the Lion stares at him like the request has been translated poorly from a dead Calibanite dialect. There is a silence long enough for three Watchers in the Dark to form a committee.
Then the Lion gives him one stiff and incredibly awkward hug, it lasts exactly two seconds and the marine hears the Primarch mutter "acceptable." The Dark Angel spends the next 400 years telling no one, the marine spends the next 400 years emotionally healed.
Fulgrim
“Of course, my son.”
Fulgrim hugs beautifully. Perfect angle, perfect hand placement, somehow there is lighting and a nearby cherub begins painting the scene.
The marine feels cherished and elevated, Fulgrim pulls back and says:
“Your posture during the embrace was slightly uneven, we shall practice.” Now the marine has hug training every Thursday.
Perturabo
The marine asks and Perturabo looks at him with the pure disgust of a man who has just been asked to install Windows Vista on a cogitator.
“No.”
The marine nods and leaves. Three hours later Perturabo has built an automated siege-grade compression device calibrated to simulate paternal approval. It has killed six Iron Warriors but Perturabo insists this is user error.
Jaghatai Khan
The marine asks, Jaghatai laughs delighted and pulls him into a crushing one-armed hug. “Good! A warrior who asks plainly for what he wants. Better than brooding in corners like a gargoyle.” (Somewhere the Lion sneezes.)
He claps the marine on the back hard enough to reset his heart and then makes him ride for six hours because 'the soul digests affection better at speed.'
Leman Russ
The marine asks and Russ is already hugging him before the sentence is finished. The marine’s ribs make a noise, Russ is laughs, someone brings ale, someone else starts singing, the marine is now legally part of a saga.
“Any son of mine who asks for a hug gets one! And any son too proud to ask gets two!” Russ says. Space Wolves across the hall begin fleeing.
Rogal Dorn
The Marine asks, Dorn pauses then says “yes.” The hug is firm, structurally sound, emotionally reinforced with no wasted movement. The marine feels safer than he has ever felt in his life, he also feels like he has been temporarily installed into a fortress wall.
“This was a good use of time.” Dorn says.
Then he makes a note in a tactical log: "Hugs: morale-effective. Implement sparingly but sincerely". Dorn didn't know he needed it until later when he stood alone and thought ''That was… good.'
Konrad Curze
The Marine asks, everyone in the room stops breathing, Curze slowly turns his head. “A hug?” Curze approaches like a cryptid, he wraps his arms around the marine with terrifying gentleness. It's cold, awkward and lasts too long. The marine realizes Curze has no idea when a hug is supposed to end.
“I saw nine possible futures where you asked this. In six, I killed you. In one, you cried. In one, I cried. In this one, we are both confused.” Curze whispers.
Sanguinius
The Marine asks and Sanguinius looks heartbroken that the marine thought he even had to ask. “Oh, my son.” The hug is divine. It fixes posture, trauma, hairline and one unresolved childhood issue the marine didn’t know survived indoctrination.
Nearby Blood Angels start quietly forming a line. “My lord, may I also-” one asks. Sanguinius opens both arms, the entire legion begins crying but in a beautiful way.
Ferrus Manus
The Marine asks and Ferrus looks mildly annoyed. He grabs the Marine by the shoulders and pulls him into something that is technically a hug but feels like being inspected by industrial equipment. It is brief, powerful and it may also have dented his ceramite.
“You are not weak for needing reinforcement.” Ferrus says and immediately pretends he said nothing profound.
Angron
The marine asks. Bad room, bad timing, bad everything.
“What?” Angron snarls. The Marine repeats it because apparently this son has chosen death but politely. For a second Angron looks like he might tear him apart then something in him cracks in the other direction.
The hug is brutal, trembling and almost too tight, not affectionate in the usual way, more like Angron is trying to hold together a world that was never allowed to exist.
Guilliman
The marine asks and Guilliman says “of course” then he hugs him warmly and normally, like an emotionally functional person. Afterward, Guilliman asks if this is an isolated morale issue or if the chapter requires a broader framework for paternal reassurance.
By evening there is a document titled: Codex Astartes Appendix CXLII: On Appropriate Fraternal and Paternal Physical Reassurance in Times of Strategic Distress
Mortarion
The marine asks and Mortarion stares.
“No.”
The Marine nods sadly and mortarion watches him go. Five minutes later Mortarion appears beside him like a tuberculosis cryptid and says:
“Do not misunderstand me, I refused because sentiment makes warriors dependent.”
Then he stands there silently and finally places one huge hand on the Marine’s shoulder. It isn't a hug but the emotional equivalent of finding a blanket in a plague bunker. “Endure.”
Magnus the Red
The marine asks, Magnus smiles.
“My son, what you seek is not merely contact but recognition of the soul’s ache-”
“Father, I meant a hug.”
Magnus gives him one then also accidentally shares a psychic vision of cosmic unity, ancient Prospero, the marine’s own buried loneliness and a metaphor involving a burning library.
The marine is healed, enlightened and has a migraine.
“Was that sufficient?” Magnus asks.
“Yes, lord.” The marine replies weeping.
Horus
The marine asks and Horus beams.
“Come here.”
The hug is perfect: warm, strong, charming, fatherly, the kind of hug that makes a transhuman killing machine think, “I would follow this man anywhere.”
Horus remembers the marine’s name, his squad, his last campaign and exactly what to say. The marine leaves glowing with devotion and somewhere fate starts sweating.
Lorgar
The marine asks and Lorgar’s eyes immediately go wet.
“My son…”
He hugs him like this is a sacrament and the Emperor himself might finally understand basic emotional literacy if enough people embraced sincerely.
The marine gets a hug then a sermon and a handwritten devotional pamphlet titled The Sacred Geometry of the Father’s Arms. The hug was excellent and the followup reading wasn't optional.
Vulkan
The marine asks and Vulkan looks offended because he realizes this son has been walking around not already hugged.
“My son, come here.”
The marine disappears into the hug like a child inside a weighted blanket made of volcanoes and unconditional support.
Vulkan pats his back with the restraint of a god trying not to liquefy a beloved ant. Every Salamander nearby is nodding approvingly.
Corvus Corax
The marine asks and Corax appears from a shadow.
“You may.”
The Marine nearly dies of cardiac surprise. The hug is quiet, careful and brief but not cold, Corax is very aware that some wounds don't like being grabbed. He lets the Marine choose how long it lasts.
“Do not mistake silence for absence.” Corax says afterward then vanishes dramatically because he physically can't end an emotional moment like a normal person.
Alpharius/Omegon
The Marine asks his primarch for a hug and his primarch says:
“Certainly.”
The hug happens or does it? Later the Marine receives six conflicting reports:
He hugged Alpharius.
He hugged Omegon.
He hugged a body double.
He was hugged by three operatives in a trench coat.
He himself is Alpharius and hugged himself.
The hug was a psyop to improve morale metrics.
Bloody Mary but Simon is terrified bcos he thinks that rocky and Grace are keeping him as a kind of living larder because why else would they be giving him their already scarce food
k but imagine Rocky wanting to learn about how humans became the apex predators of their planet so he has Grace “hunt” him in the biodome as an experiment and during it he thinks Grace isn’t trying or taking it seriously which is bad bad bad because this is for research purposes
only for Rocky to get more and more tired as the experiment goes on just to realize that Grace isn’t which makes him panic so he puts as much distance as he can between them and finds a (hopefully) safe spot to sleep and when he wakes up the human is crouching over him like “got youuu” and Rocky has never shrieked so damn loud before in his life
I know there's a popular headcanon that Grace's crew died because of feeding tubes malfunction (based on the paperwork Grace was doing right before the explosion), but — in the book he specifically says that even after the accident he kept dealing with that same paperwork on minor Hail Mary issues, so I doubt that feeding tube problem was left unaddressed. May I offer instead:
Grace was put into coma by the people who cared about him. They (especially Yáo being Yáo) probably double-triple-quadruple checked everything. They watched him sleep for those first few days — I doubt they went into coma immediately after leaving Earth's orbit. They probably talked to him, assuring him that he'll be okay.
Ilyukhina's coma procedure was probably supervised by Yáo. He made sure that everything was in order, but — he is just one man and he is not a doctor. There was much more room for mistakes.
When Yáo went to sleep, he was alone. He had to rely on the technology completely.
having Big E as a favourite character sounds like it should be a red flag, and maybe to some it is. but god i am just. extremely enchanted by this specific archetype of. "corrupted messiah" / tyrant that takes it upon themselves to steward their charges, through any means necessary.
like i am 100% absolutely certain that he is motivated by a deep, fundamental love for Humanity, as a whole. Love for their capacity for brilliance, love for their capacity for beauty and knowledge. a significant chunk of the Imperial Palace is a repository of Humanity's entire history, ranging from priceless works of art, to milestones of human achievement over the ages. The Palace ITSELF is a monument to what Humanity can offer, a vast mix to showcase architectural styles over the ages. The Emperor LOVES them, he HOARDS these things. He considers them precious and priceless.
he is also fundamentally Outside of humanity. he stands Apart, and, ultimately, Above them all. He may love them deeply, as a whole, but he has no trust in them whatsoever. No trust in their free will to be capable of forging a path in the Galaxy for themselves without tumbling into total annihilation.
And to him, tyranny is the only answer. He knows it best for them. He can guide them into a future worth living in. Stamping out the dissenters, the rebels, it matters not - he is doing this for the Greater Whole, after all.
Like, i love this. i LOVE this. the sheer HUBRIS. I am aware he is more often a plot device rather than a character, but there IS a very peculiar sort of character sitting in there.
Behold, my newest RP character: Space Wolf veteran Jørulf. 🐺
He is a Grey Hunter, former Speaker of the Dead and is not exactly what an average Imperial citizen would call a loyalist.
He has seen and done so many things in his long life and is just too old for everyone's shit. But he is good humoured and a good sport most of the time :)
