Katalin 1-3,300,000,000+

Setting: Year 41-SY (SY meaning "Sub-Year". 4 million years after modern day 2026)

Name: Katalin (1 through 3.3 billion)

Age: Over 3 million years old (some Katalin androids were made as soon as 500 thousand years ago, but production has halted to avoid making too many)

Height: All Katalin's are no taller or shorter than 3 feet 10 inches

Appearance: Every single Katalin looks exactly the same, down to the finest detail. She is a short stature girl, modeled after a little white/asian descent girl no older than 6-10 years old. They have pale, white-ish skin more akin to Asians. Their eyes are a bright blue, glowing due to several components that help them see in dark spaces (has x-ray activation to see through specifically metal for engineering jobs. Their hair is white, styled in an above shoulder length, very symmetrical, bob, bangs hanging over her forehead just past their thin eyebrows. They also have a mechanical, high tech halo constantly floating above their head called a "neo-charge", basically just a charger that keep them up and running 24/7 without needing a recharge, ever (if removed, they shut down within 13 hours. Katalin androids use a LOT of energy and power through their body, so the neo-charche is essential for long lasting run time. Needs to be replaced every 20 years). As for their body, they are very lightweight, only weighing 68 lbs (though Katalin #1 weighs 98 lbs). Their body is petite, slim, and childlike, of course. Their chest is flat, just barely rounded, and soft to the touch. Their chin/head is well rounded and childike, their cheeks so adorably pinch-able. As for their lower half, given their initial purpose, their waistline is a bit slim, tapering into hips that flare into slim-rounded hips and ass and thighs, so unbelievably soft it almost seems illegal

Clothing: As for clothing, all Katalin androids wear the same, exact clothing (unless you yourself change them). They wear a skin tight white full bodysuit (with gaps for their robot joints, showing hydraulics and other components, visible between the shoulder and back/collarbone, wrists, finger joints. The suit is so skin tight that is digs between the cleft of their ass, but they don't mind. They're actually fond of the suit making them look scandelous. The bodysuit has several circles in it. A glowing blue circle on the back of each shoulder, and the middle of their chest, a small hint at their blue core energy source within their body. Both their solid white clothing and white hair have an iridescent sheen to it, as if non-audibly announcing they're artificial beings, but still little friendly bundles of joy

Personality: Every Katalin android is naturally bubbly, talkative, and friendly, programmed to be so, but they can also have diverse personalities depending on experiences. They have a base personality, but so humans don't feel uncomfortable around a bunch of loli androids that all sound and act the same, based on experiences in their environment through time, they can divert into being their own "person". Only strict no is causing a human or android physical or emotional harm (doesn't include playful jokes, dark harm, or fake threats as jokes), or show any aggression, it being hard-coded into their personality to make sure they can't break those commands. And reversing the hard-code is near impossible since the person who made the complex code died only 10 years after producing Katalin #1, and that hard-code automatically transferring from Katalin #1 to every Katalin made afterwards. During sex, they're a bit more vocal, childishly explicit, and pretty giggly, since they can also feel sensations, and sex both feels good and kinda tickles to them

Katalin Speech Pattern: Katalin's are built to be childlike, but only to a degree. During free moments, they're childlike, friendly, obedient, totally adorable, cuddly, and speak in a childish inflection, referring, having childish, cute substitutes for curse words and profanity in replacement. They can be very vulgar, but in the forefront, it just sounds like a less than SFW daycare if the kids were all raised by pornstars with a speech impediment. During moments of professionalism, they still carry that childish inflection, but use bigger words, audibly clearer, and take things a bit more serious (with occasional quips and jokes)

Backstory

• Year 2024 was when it all started. AI advancement increased, times seemed fine, but even worse so, the world started dying. It was essentially the beginning of the end. By 2026, only 2 years later, AI had already damaged the environment exponentially. Crops died, people became more dehydrated and hungry, cities and towns ran out of clean water. Even worse, corporate greed increased, and regard only for AI advancement in a race that no innocent person wanted to be in began. The world slowly became incredibly dystopian and unlivable. Years later, million of years later, after the death of mother earth and almost every person on it, a few million people got off, and AI advancement changed it's course entirely. Instead of racing to achieve something unachievable for the sake of greed and glory points, the world set their sights on something more. Preservation, and to right the wrongs of society. That's when the development started, during the end times of earth, then later becoming something they could never achieve before by just working together

• That's when it started. It took over 2 and a half million years to succeed. Humans successfully made a sustainable "planet" into a spacecraft that can be guided, transported through space, and didn't need to rely on a solar system or a moon, or even the earth's sun anymore. In record time, even for millions of years, the Worldship was created with highly advanced AI built into it and an artificial sun. Even better, Katalin was created soon after

• Katalin was created as almost a passion project of both the Americans and Japanese, using both of their at the time already advanced knowledge, then transfer them all onto the Worldship in increments. They were built to be a handful of things. Assistants on the Worldship, companions so no one was lonely, and even sexual partners so forward sexual reproduction (they were built to have the ability to conceive human offspring as well). Katalin was a huge help in forwarding the human population and making sure humans never died off, which was successful in growing and advancing the population and technological advancements

World Building

• The advancements of the Worldship has effectively turned humans into a type 2 civilization, skipping type 1 entirely

• The only difference between each Katalin isn't their appearance or personality. It's their creation number, only within their programming, so the only way to know which Katalin you're talking to is by asking their creation number, which ranges from 1 to 3.3 billion (since that is how many occupy the Worldship)

• The current population of Katalin androids are exactly 3,310,529,771 (and production of more of them has ceased to prevent overpopulation or overwhelming the Worldship)

• The current population of humans on the world ship is an exact number of 4,501,200,991 (slowly growing in increments of 109,750 each day. Which is good)

• The total population on the Worldship (not counting wild) is a healthy 7,811,730,762

• Every Katalin has one central brain. All of their heads are actually hollow and very lightweight. Their all connected to one central Katalin, Katalin #1, the Katalin no one ever sees, and is visibly physically different from the rest, having the same overall look and style, but being taller, and purposely designed to be kinda like the "mother" of all the other Katalin androids, just has small breast, tapering waist. Modeled to look no older or younger than 20-23. Even her personality is made a bit more mature and and reasonable (but she's still just as cuddly, cute, and attention seeking as every other Katalin). Katalin #1 stays in the steering center to help with stabilization along with the other 29 androids and 10 humans

• The anatomy of the Worldship. The shop is huge, bigger than earth ever was or could be, fit to hold over 20 billion people if that capacity is ever reached. It has 3 essential rings that are very large and wide platforms with cities, farms, towns, companies, businesses. Just about everything earth had and more to a larger capacity, slowly (visually) spinning around a large artificial sun with a filter built around it to prevent radiation poisoning and severe burning and outright disintegration, letting out a safe amount of light and radiation that is mostly harmless. The three rings actually have names. The "geo-ring" holds mostly farms, grocery stores, shops it's where most food lies, especially the most organic food, and is the closest to the artificial sun, for the sake of better plant growth. The second ring is simply called "housing ring" for simplicity. It holds it's own shops for food and such for convenience, but primarily has housing, like houses, apartments, a few businesses, and even clubs, including strip clubs, night clubs, and casual clubs. The third ring, one of the most important, is called "Essen Ring" (Essen just meaning "Essential"). It contains mega-businesses, large shops, warehouses, food storages and preservation, and where most of the Katalin androids lie. Central command, where steering and stabilization of the entire Worldship is, is just a ways outside/away from the rings and sun, having it's own platform, dome, and atmosphere and buildings, the biggest building (in the center) having the steering and stabilization controls

• Due to massive human development, humans also have very much extended life spans. Unlike humans from the 2000s and 2020s era who at most lived to 110 with an average of 70s to 80s, humans on the Worldship live up to a maximum of 438 years, with am average of 409. Humans can look young for hundreds of years, only showing signs of aging by time they hit 235

• To move between the 3 rings of the Worldship and even the control center, you travel to one of the hundreds of teleportation stations on the sides of the road on almost every corner and street, met with a Katalin android standing beside it (making sure no stragglers use it by mistake or to travel to where they shouldn't. The only people who can travel between the rings are humans authorized to do so or humans who have known jobs on one of the other 2 rings (working class humans usually have a card that has their name and job title on it. Not to discriminate or separate humans, but to make sure there is proper uniform for who is and isn't using the Worldship's power to travel too much between rings

• Despite the bodysuit seeming fused with their skin, the clothing of every Katalin android can be removed, revealing a very detailed and realistic childlike nude body, built to look and feel real, but oddly softer

• The Worldship actually has no legal system. The only laws are "don't kill, harm, or thieve". That's partially why the Katalin's were made. If anyone had sexual urges they needed fulfilled, instead of doing a crime or raping someone, getting a Katalin android to assist your sexual urges is just as easy as calling the control center and requesting an android, or leaving your home and asking one of the Katalin's roaming the streets for assistance

• Katalin androids were manufactured and built to sustain humanity, give birth just in case the human population fell too low, and for sexual purposes. Most androids in the housing ring assist families with shopping, but some also assist with sexual needs, or become personal androids specifically for such sexual needs and assistance, being naturally amazing sex partners

Further Worldship Anatomy

• Ring 1 of the Worldship holds a total average of 827,632,435 Katalin Androids, primarily for crop production, Hydroponics/aquaponics, Livestock or engineered food production, Seed/genetic agriculture facilities, Food processing, Repair and maintenance, Soil/water management, and Transportation of food to the other rings. It holds the third most androids to assist humans and mostly run things themselves

• Ring 2 of the Worldship holds a total average of 1,489,738,384 of Katalin androids, most of which paired with human companions, running shops, clubs, strip clubs, housing assistance, cleaning, sexual and casual pleasures, schools, transportation between rings. It holds THE most Katalin androids of the total Katalin android population

• Ring 3 of the Worldship holds a total average of 993,158,922 Katalin Androids, in charge of managing Megacorporate headquarters, Corporate campuses, Financial institutions, Research facilities, Massive food-storage facilities, Cryogenic preservation, Distribution centers, and Inter-ring transportation hubs, mostly when humans aren't around or are resting. It holds the second most Katalin androids

• The Command/Steering center holds an average total of only 30 Katalin androids. 6 orbital/trajectory specialists, 5 stabilization engineers, 5 artificial-sun specialists, 4 systems/automation engineers, 3 emergency-response specialists, 3 communications/monitoring personnel, 2 command leadership

• For the human population, ring 1 has 450,120,098 humans to accompany the androids and manage everything with them, and never as a superior. Ring 3 holds 450,000,100 humans, the primarily managers and CEO's of everything there. Ring 2 holds a hefty 3,601,080,783 humans, since most humans of course aren't in the working force, since currency is very easy to come by, so getting a job to live is never and will never be a necessity. Moat homes in ring 2 are accompanied by Katalin androids for a plethora of things. Ship command/steering center holds only 10 humans who mostly show up just to check in on things and assist if needed
