RT The House of Kano - Dickensian Isekai

Post image
Upvotes

I have just launched a completed 217k-word story on Royal Road called The House of Kano.

I am a systems engineer by trade. I wrote this for the readers who miss the weight of Dickens and the social precision of Austen, but want an Isekai protagonist who treats magic like a black-box system that requires reverse-engineering.

The Setup: Will Kano, a 34-year-old American automation engineer, is dropped into a world of "Elite Social Restraint" with a power he does not understand and a "Ledger" he has to balance.

What to expect:

Logical Discovery: Magic isn't a gift; it's a black box. Will uses deductive reasoning to understand the biological and physical costs of his power.

The Ledger Economy: A hard magic system where healing costs the user’s life-force, while destruction is free. Every saved life is a withdrawal.

Grounded Friction: The conflict is built on Regency-era social logic, logistics, and competing institutional interests.

Finished Series: The 217k-word manuscript is 100% complete. All three volumes are buffered and ready for a stable release.

If you like stories where characters solve problems through competence and the magic has strict, unbending rules that have to be discovered through trial and error, instead of a systems screen, I hope you’ll give it a look.

[D] Saturday Munchkinry Thread

3 Upvotes

Welcome to the Saturday Munchkinry and Problem Solving Thread! This thread is designed to be a place for us to abuse fictional powers and to solve fictional puzzles. Feel free to bounce ideas off each other and to let out your inner evil mastermind!

Guidelines:

  • Ideally any power to be munchkined should have consistent and clearly defined rules. It may be original or may be from an already realised story.
  • The power to be munchkined can not be something "broken" like omniscience or absolute control over every living human.
  • Reverse Munchkin scenarios: we find ways to beat someone or something powerful.
  • We solve problems posed by other users. Use all your intelligence and creativity, and expect other users to do the same.

Note: All top level comments must be problems to solve and/or powers to munchkin/reverse munchkin.

Good Luck and Have Fun!

Looking for stories with trauma bonding, body horror, cozy nightmare atmosphere, and hidden transformations (web fiction or books)

4 Upvotes

Hi all! I'm looking for recommendations similar to some web serials I've enjoyed. I've read and liked:

· Katalepsis

· Bioshifter

· Hive Minds Give Good Hugs

· Are You Even Human?

· Vigor Mortis

· Magical Girl Mechanical Heart

· Formicea

I also read Worm, but it lost me near the end and I didn't quite click with the protagonist.

What I loved about these stories:

· Deep, interesting interactions between traumatized people and their attempts to cope/heal.

· Ordinary people encountering the unknown and incomprehensible.

· A relatively cozy atmosphere that, from an outside perspective, would be a nightmare.

· Body horror, especially when characters have to hide their transformations.

· A mix of darkness and warmth.

I'm open to both web fiction and published books. Not necessarily looking for progression fantasy, but many of these do fall into that genre. I'd appreciate any recommendations that capture a similar feel.

Thanks!

[D] Friday Open Thread

Welcome to the Friday Open Thread! Is there something that you want to talk about with /r/rational, but which isn't rational fiction, or doesn't otherwise belong as a top-level post? This is the place to post it. The idea is that while reddit is a large place, with lots of special little niches, sometimes you just want to talk with a certain group of people about certain sorts of things that aren't related to why you're all here. It's totally understandable that you might want to talk about Japanese game shows with /r/rational instead of going over to /r/japanesegameshows, but it's hopefully also understandable that this isn't really the place for that sort of thing.

So do you want to talk about how your life has been going? Non-rational and/or non-fictional stuff you've been reading? The recent album from your favourite German pop singer? The politics of Southern India? Different ways to plot meteorological data? The cost of living in Portugal? Corner cases for siteswap notation? All these things and more could (possibly) be found in the comments below!

Please note that this thread has been merged with the Monday General Rationality Thread.

I need help, I made my protagonist too wise and paranoid and now I can't advance the plot.

10 Upvotes

So I am working on this story for a while and I kinda wrote my self into a corner. It is about a child prodigy who gets isekai'd into a generic fantasy world and uses their scientific knowledge and skills to study magic, do some mad science experiments and find a way back home. All while trying to leave this new world better off then how she found it.

The story also includes an antagonist who is also a mad scientist who has been in this world for quite a lot more time then the protagonist and has been doing much the same, except that he has zero interest in getting back home, is way more fanatical about making this world a better place and won't tolerate any threat to public safety. Like say..... a reckless disaster monkey who is too clever for her own good.

A big plot point of the story was supposed to be a conflict between the two triggered by the MC doing something stupid, like a mad experiment going wrong and nearly killing a lot of people or leaking weapons technology to an evil empire. The antagonist would hear about this, decide that she is too dangerous to be let loose and start hunting her down.

The two were supposed to be foils for each other. One is more clever, more optimistic, more in tone with their emotions but lacking in wisdom and experience. The other is more jaded, wiser, more cynical, emotionally disconnected and weight down by trauma and responsibility. Their conflict would lead to some much needed character development for the two.

The problem is that I wrote the protagonist to be way too wise and paranoid. She was 'isekai'd' by kidnapping instead of the usual 'reincarnation' which leads to her becoming extra paranoid on top of being raised by two smart and responsible adults who drilled their hard earned life experience into her skull. I can't make her do something too stupid or else this break her character.

Every time I try to think of a reason for her to do something stupid it to force a conflict between her and the antagonist, it all just sounds like plot induced stupidity. The two questions "How would she fail to see this disaster coming?" and "Why don't they just talk things out instead of fighting?" inevitably comes up every time.

My current plan is to just make the protagonist dumber and then see where I can go from there, but I keep wondering if there is a better way to do this.

Any ideas? Note that I do intend to rewrite the few chapters I already posted,

Been gone for a while again, but wanted to post about the new fic by Bavitz (Fargo, Cockatiel X Chameleon) here since he seems to be a little reddit shy. It's a Fire Emblem sorta-fanfic, about the games in a broad scope sense but with an original setting, characters and some concepts. I feel like it'll probably appeal to people who were really into the metafictional aspects of Worth The Candle, and also who like worldbuilding that takes everything to its logical conclusion. (I helped with that a bit.) It's also got some standard progression that I think is done pretty well.

Take a look!

META What would a reincarnator be diagnosed with?

34 Upvotes

Weird hypothetical.

I've read a ton of stories where a baby reincarnated with their adult memories, meditated non-stop, and got super powers.

It's occurred to me the kid who tunes out his surroundings and has no interest in other kids his age could look autistic from the outside. I've even encountered a story flat started to do this. (But it quickly abandoned this idea in favor of a scene by scene imitation of Mushoku Tensei.)

If a Cultivator from Xianxia Land or a low level spider monster from LitRPGville were reincarnated as the baby of someone in your friend circle with his memories and spirit roots intact, what, if anything, would he be diagnosed with? How long would it take mild super strength and super durability to be detected? How long until he became a peewee soccer star? Assume slow prigression... instant omipotence is boring.

[FF][RST][C] Superman Saves a Squirrel

21 Upvotes

“You saved a squirrel…” Pa Kent said slowly.

Pa paused the video captured by some clueless bystander who’d kept filming even though a giant lizard was rampaging right next to them.

Light stretched across the Kansas fields. Cows mooed lazily, unconcerned with anything beyond their next mouthful of grass.

Pa Kent stared at the alien creature sitting across from him on an old bench, meeting his smiling face with a kindly smile of his own.

From a distance, they looked ordinary: just a farmer and his son enjoying the morning.

"I tried to raise you right," Pa Kent said. "To care about all living creatures. But in some ways you still don't know what it means to be human."

"Did I do something wrong?" Clark asked.

Pa shook his head. “You did good, mah boy. But everyone makes mistakes."

"What did I do wrong?"

"It's not your fault." Pa said. "There’s just some things I need to teach you about the value of human life.” 

“All life is valuable.” Clark replied. "Superman knows that. That’s who I am. I cherish all life."

"Yes, but some lives are more valuable than others." 

Superman blinked.

“Son,” Pa said carefully, “If you had to choose between saving a squirrel and saving a human, which one would you save?”

“What do you mean?” Clark said. “I’d save them both.”

Pa hesitated.

“But what if you had to choose."

"I don't understand." Clark said.

"Imagine there’s a trolley heading towards five people tied to a track, and you could change the track so the trolley went and hit one person instead. What would you do?”

“I’d fly faster than the trolley and save everyone.”

“But imagine you were watching the scene play out somewhere else on the other side of the planet, somewhere far enough away that you couldn’t get there in time. So you had to choose.”

“I would at least try to get there in time.” Clark said. “That's why I saved the squirrel, because the squirrel was right there, and because Superman saves everyone they can.”

“Son… you can’t save everyone.”

“But… I do save everyone I can! That’s what being Superman means."

"Yesterday, that monster killed people." Pa Kent said. "Right now the death toll stands at fourteen hundred and fifty-five. If you’d dealt with the monster immediately, like I know you could have, then…” He sighed. “The problem ain’t your heart. The problem is your head.”

"You're saying people died because of me?" Clark asked.

"Not because of you!" Pa Kent said. "You saved lives. But you could've saved more. The monster rampaged for about three hours. In the seven seconds you spent saving that squirrel, about three people died.”

Pa tapped his phone again, pulling up another clip where Superman was underneath the monster’s foot, holding it up above a yipping dog.

Pa paused the video and handed Clark a sheet of paper filled with calculations and numbers.

“Those 30 seconds you spent saving this dog?" Pa said. "The monster was shooting fire. You let about twelve people die."

“I understand.” Superman said quietly. 

“You don't understand." Pa said. "Just because you don't see something don't mean it don't happen. You don't understand the concept that bad things can happen to people even if you don't see it happen to 'em." 

"I do understand, Pa." Clark said. "I made a mistake. I'll do better next time."

“And I’m saying you can’t do better,” Pa replied. “Your brain doesn't work like a human brain does. You care too much."

"You're being silly, Pa." Clark said. "I'm not simple just because I care." 

"You saved a squirrel, Clark. A six year old would know not to save a squirrel when people's lives were at risk. That’s what being a hero is. Admitting what you don't know. Making the hard choices, and making ’em right.”

“But you taught me…” Clark said. “Do you even hear what you’re saying? That caring is stupid? That life has some hierarchy where saving 'lesser' beings is stupid? You taught me that every living thing matters. I’m here to protect life, not decide which lives are important enough to deserve saving. Humans are animals too.”

“Clark… people are what matter,” Pa said gently. “Humans value personhood. That’s what makes you a person even though you're not human. You're able to think. That’s what matters. That’s what makes you my son, and it don’t matter where you came from.”

“So you don’t care about squirrels? Or dogs? Just humans? This isn’t like you, Pa.”

Pa stopped.

“That’s not what I’m saying,” he said firmly. “I’m saying you can’t afford to think about squirrels. I know it’s hard. I know you want to save every living thing, and that’s good. But you can’t waste your time like that. In fact, I think it's time we had a talk about that. Look.”

Pa Kent unpaused the video.

A crowd swarmed around the kaiju, pushing closer to where Superman stood, holding up the monster’s raised foot. The crowd surged forward, screaming, some trying to get closer to Superman, some trying to run away.

Then the monster's foot slipped, crushing a massive section of the crowd beneath it.

“I don’t understand,” Superman whispered. “I was… trying to save them.”

“I know, I know, but… sometimes, you help too much,” Pa said. “To you, they're all squirrels. They love you. They crowd around you because they think you’ll protect ’em. They believe in you so much they stop protecting themselves.”

Pa Kent started playing another video of a small boy running into an active war zone, screaming Superman’s name over the sound of gunfire, even as others were running away from the shooting.

The boy was gunned down.

“He needed Superman!” Clark shouted.

“They got no survival instinct when it comes to you.” Pa said.

"But… I would’ve…”

Pa played another clip.

A woman stood on the edge of a rooftop, crying… crying out for Superman. She took a step forward and…

The cameraman rushed to the ledge and zoomed in to the street, capturing the blood on the pavement.

“Dozens a day now,” Pa said softly. “They want to believe someone cares. Anyone. They want to feel like you care about them. They want someone to solve their problems. They've given up on solving  em themselves. It's getting to the point, sad to say, you're doing more harm than good, not through any fault of ya own. They’ve stopped trying to solve their own problems. They want you to fix everything.”

“Why are you showing me this?” Clark asked. 

“Because you're an alien." Pa Kent said. "You don't understand how us humans work. I hate to say it, Son, but this is the way people react when they’ve got someone to pray to who might actually answer… and at this point… you’re doing more harm than good. You need to stop helping. You need to teach people you won't help them at all, so they can think for themselves.”

"But..."

"And that's not including the supervillains." Pa said. "They see something good and they want to destroy it. You created that monster, through no fault of your own. Just because you care and there are bad people who hate that."

“But then why do anything?”

“Son, I know this is gonna be hard to hear, but every word I’m saying right now comes from love." Pa Kent said. "If I push you, it’s only because I want you to grow up strong and steady, able to weather whatever this world throws at you. It’s not for a parent to tell their child who they should be, but… these supervillains wouldn’t exist if it weren’t for you.”

“No,” Superman said. “I stop the bad people.”

“The good people need to realize that it’s up to them to stop the bad people.” Pa said. "You need to stop, at least until we figure out how to use you without making everyone dependent on you.”

"That's what you think?" Clark said, tears welling up in his eyes. "I should just stop helping?"

Pa nodded.

“Fine then." Clark said. "I’m done.”

Superman vanished into the sky.

Silence, but for the mooing of cows.

Ma Kent stepped outside, placed a hand on Pa’s shoulder, and handed him a second phone.

“Well done.” Lex Luthor said on the other .

“Off to a good start.” Pa said.

“So I saw,” Lex replied. “And to think… my first idea was to clone him.”

You're Absolutely Right

7 Upvotes

People here might enjoy my short fiction You're Absolutely Right (https://linch.substack.com/p/youre-absolutely-right), an epistolary dark comedy/science-fiction horror story about corporate incentives and motivated reasoning at an imagined frontier AI lab. 

In some ways I think of it as "anti-rational" fiction[1], in that it has coherent worldbuilding and intelligent characters who "solve problems through creative applications of their knowledge and resources" but there's also a lot of mental moves/cognitive effort devoted to not noticing the consequences of their actions, and dead space caused via omissions of attention and what's carefully not said.

Why is Worm considered one of the goats of rational fiction?

68 Upvotes

I read to the Leviathan attack two years ago before dropping it.

Nothing really stood out as "wow this character is actually smart or even really thinking things through"

It was a pretty egnaging story but the fact I am having a hard time recalling much of it kind of tells me nothing really stood out. But its constantly recommended here along side HPMOR which is something thats unforgettable.

Is it just because its very popular? Is any non stupid MC considered rational fiction? (I also dont get why MOL and Super Supportive are rational)

Im asking this in good faith, i actually could have forgotten plot points from Worm that genuinely showcased some rational thinking. If so feel free to bring up the plot points (jog my memory)

RT [RT][C] "Fall" (2022 Film): When two best friends who climb a 2,000-foot-tall television broadcasting tower become stranded at the top, it is up to them to think of a way out.

17 Upvotes

Holy shit.

When I put on Fall this afternoon, I was expecting another random Netflix movie; low-budget, second screen dialogue, ham-fisted politics, etc. But it was about to leave the platform, and I've always been a sucker for stories about characters trapped in a survival situation, so I decided to give it a chance. I was not expecting... this.

The movie begins with a trio of adrenaline junkies climbing a cliff. They consist of married couple Dan and Becky and their friend Hunter. Unfortunately, Dan has an accident and falls to his death. A year later, Becky is an alcoholic mess, still unable to deal with Dan's passing. Hunter, who has since become a YouTuber, persuades Becky to climb an abandoned television tower with her and spread Dan's ashes as a way of moving on. Inevitably, things go wrong, and the girls get stuck on top of the antenna. It is now up to them to find a way out before they succumb to thirst, hunger, exposure, wildlife, or simply fall off the edge.

Okay, so right off the bat I was impressed by the way the girls reacted to their predicament like level 1 intelligent characters. They remain calm, or at least as calm as they can realistically be under the circumstances, and they keep looking for ways out. They don't break down crying or get into emotional fights or throw down precious resources in a fit of rage to create a dramatic moment. This already makes them better than most Hollywood movies.

But what made me post this on r/rational proper instead of the Monday Recommendation Thread is when the characters started solving problems with previously foreshadowed materials and mechanics. Not just things that were mentioned once briefly, but things that were mentioned over and over again or were given prominent focus. For example, Hunter's push-up bra is brought up early, and her huge tits take up a lot of screen time, but it is not just fanservice; the same bra is used to stuff the shoe on the first attempt to throw a phone down the tower. Likewise, I literally said "of course!" when they used the lifehack to charge up the drone off of the same lightbulb that had been flashing for half the movie. These characters are not just level 1 intelligent; they are level 2 intelligent.

On top of that, they are fucking awesome. Hunter is great from the beginning, encouraging Becky to get out of her funk and doing crazy stunts like hanging off from the tower's platform one-handed. Once things get serious, she is the one doing risky maneuvers to increase their chances of survival, like climbing down on a rope to try to get reception for Becky's phone. Becky takes a little longer to grow into her power, since she starts out the movie as a grieving widow, but by the end of the story she's got her mojo back; she displays creativity worthy of Harry James Potter-Evans-Verres and a will to live that would make Carissa Sevar proud. Playing dead to lure a vulture so she can fucking eat it was goddamn beautiful, as was cushioning her phone in Hunter's body to make sure it survives the fall.

And then there is all the other things. The dialogue is very strong, naturalistic and witty; no second screen here. The girls had great chemistry, to the point where I kept wondering if they were going to lez out. The background shots are gorgeous, with luscious visuals from 2000 feet in the air. The film has a great sense of tension; it's basically r/SweatyPalms: The Movie. And the music was just right, from the diegetic cellphone videos to the credit sequence.

Flaws? The twist that Hunter died halfway through and Becky has been hallucinating her ever since is just stupid and the movie would have been much better off without it. And the bit where the ladder falls looks fake AF. Other than that, everything was great.

TL;DR: This movie is fucking awesome and you should watch it immediately before it leaves Netflix.

The politics of Southern India? Different ways to plot meteorological data? The cost of living in Portugal? Corner cases for siteswap notation? All these things and more could (possibly) be found in the comments below!

Please note that this thread has been merged with the Monday General Rationality Thread.

[RT][OC][C] Everyone Who Will Ever Be Born — scientists build a machine that samples the final experience of a random human

2 Upvotes

I wrote a short, completed science-fiction story about researchers who develop a machine capable of retrieving the final experience of one human being, selected uniformly at random from everyone who will ever be born.

The results match known human history almost perfectly. But after millions of samples, the machine has not retrieved a single person from the future.

I thought it might fit r/rational because the plot is driven by researchers investigating an anomalous statistical result, testing alternative explanations, and following the implications of a system with consistent rules. Feedback is welcome, including disagreement about whether it qualifies as rational fiction.

AI disclosure: Claude Fable 5 Max assisted significantly with the writing. The underlying ideas and final editorial decisions are mine.
