Littoria

Stage 4 – “The Cradle” (final)

The person disappears. Not physically—they continue to walk, eat, and talk. But within them, there is no longer an autonomous personality. They become a relay.

Physics:

The body retains all its functions, but operates automatically, like a biorobot. The patient can drive, cook, and write letters—but without emotion or initiative.
· The human metabolism is completely replaced by a new one: it can go without food for weeks, feeding only on salt water.
· The skin acquires a permanent pearlescent hue that glows faintly in the dark.

Mental:

The patient begins to attract others. People in stages 0-1 are intuitively drawn to them, sit next to them, and want to talk to them. They don't try to persuade others—they simply sit silently, and others develop an overwhelming desire to "find out what they know."
His speech is a condensed version of the voices of everyone who has ever been inside Littoria. He speaks with the voice of a dead child, then an elderly scholar, then his own sister. He has no control over it.
· He stops sleeping - his brain operates in a "wakeful unconscious" mode, like that of dolphins.

Critical Sign: The patient doesn't try to escape. He tries to return. He writes letters, leaves coordinates, hides maps in books. He's not an enemy—he's a beacon. He lures others not out of malice, but out of sincere love, because Littoria teaches him to be "happy" through absolute solitude.

Stage 3 – “Siren” (1–3 weeks)

The man is physically healthy, but socially dead. This isn't madness in the classic sense—he's rational, calm, polite. But he's gone.

Physics:

His eyes are completely white, without irises. His vision is reconfigured: he sees not shapes, but temperature contours and the emotional fields of people.
· The skin on the arms and legs begins to peel off in layers, but underneath there are no wounds - only a smooth, pearlescent layer, similar to the inside wall of a shell.
· Pulse and breathing are synchronized with the tides - the rhythm of breathing accelerates and slows down strictly in time with the phases of the moon.
· The body stops producing sweat in the usual sense, instead secreting an oily mucus with a salty taste, which is called "Littoria ambrosia".

Mental:

· Complete apathy towards life outside the Littoria. When asked, "Do you want to live?" the patient sincerely replies, "My body is alive. But I'm not here anymore."
· Empathy becomes total: the patient feels the pain of any person within a 100-meter radius and reacts to it with crying or a smile, depending on whether Littoria “wants” to accept this pain or reject it.
The ability to "transmit" thoughts to other people appears in stages 1-2. Patients begin to see identical dreams, even without communicating.
· A person stops calling themselves by name. They say: "I am the part that remembers the light." Or: "We are the passage. Those who listen are already passing."

Critical sign: The patient begins to crave water. Not drinking water, but any standing water—a puddle, a bathtub, a toilet, the ocean. They can simply lie in the water for hours, eyes closed, smiling. This isn't suicide—it's a longing for a return. Littoria is located in the ocean, and any water is a "conduit" to it.

Stage 2 – “Abyss” (72 hours – 1 week)

A turning point. The person is almost completely part of the Littoria collective consciousness, but the body is still functioning.

Physics:

The eyes change color: the irises become grayish-whitish, like those of deep-sea fish. Vision is preserved, but the person begins to see warm currents (bioluminescence) in ordinary air—this is a projection of Littoria's internal glow onto reality.
· The heartbeat slows down to 35–40 beats per minute – as in suspended animation.
Loss of appetite for regular food. The patient begins drinking large quantities of salt water, simulating the salinity of the ocean. They can drink seawater without gagging.
Transparent, scaly patches appear on the skin—not rough, but smooth, like jelly. They don't hurt, but underneath, the skin becomes translucent, revealing blue veins.

Mental (the scariest):

The patient stops recognizing loved ones in the mirror. He looks at his reflection and says, "Who is this? He looks so sad. He needs to go down too."
· Speech becomes “choral”: a person speaks and simultaneously moves his lips in rhythm, as if repeating someone’s words off-screen.
· The memory of one's own life is fragmented. The patient remembers his name, but not what he did yesterday. However, he remembers the structure of the Littoria's gastric chambers in minute detail—all the passages, all the passages, even though he's never been there.
An acoustic hallucination appears—a constant whisper, similar to the rustling of waves. The voices of deceased expedition members can sometimes be discerned in this whisper.

Critical Sign: The person begins to draw. Everywhere. On walls, paper, their own body—spirals and circles that form a map of Littoria's respiratory tract. They do this unconsciously, in a trance.

Stage 1 - "Nereid" (12–72 hours)

Here, Littoria begins actively "editing" her personality. This is no longer background noise, but a systemic change.

Physics:

· The skin becomes cool to the touch, but the person himself does not feel the cold - thermoregulation is disrupted.
· The venous pattern on the wrists and neck changes color to pale blue, as if the blood has become less saturated.
· The reaction to pain disappears: a person can bite their lip until it bleeds and not notice.
· Blood biochemistry shows abnormally low levels of cortisol (the stress hormone) – the body stops panicking even in dangerous situations.

Mental:

· A feeling of longing for a place you've never been. Right now, sitting in the office or at home, a person begins to cry because they're not "there."
The ability to think abstractly declines, but empathy soars to its limit: a person feels the emotions of everyone around them as if they were their own. If a neighbor is irritated, they are irritated. If a child is crying next door, they cry with them.
· False memories appear: a person “remembers” how he has already descended into the depths, although he has never done this.

Critical sign: The patient begins to refer to themselves in the plural. "We need to eat," "We're tired." When asked, "Why us?" they respond, "Well, there are two of us? Can't you hear the other one?"

Stage 0 – “Orpheus” (0–12 hours after exposure)

Initial stage. The person is not yet aware that contact has occurred. Littoria does not bite or infect through wounds—it affects through air, water, and even dreams.

Physics:

· A light feeling of euphoria, similar to breathing pure oxygen after a long period of stuffiness.
· Pupils dilate unevenly (anisocoria).
· Natural shaking (tremor) disappears - hands become perfectly calm.

Mental:

· An obsessive feeling that you are not alone in the room, although there is no one there.
· Dreams become colorful and incredibly detailed - they always include water (ocean, rain, puddle).
· The person begins to forget words. Not forever, but for a few seconds: instead of "table," he says "whatever it's on" and laughs, not understanding why.

{{user}} finds his sister. She hasn't mutated or gone mad. She's sitting in the deepest room, surrounded by dozens of other people who look calm and pure.

The sister explains: “Littoria doesn’t kill. It gives what we can’t give ourselves—the silence of our own Self. There is no pain here, because there is no ‘me’. There is only ‘we’. Remember how I screamed at every sound? Here, the sounds sing. Come back. Become a part of it.”

{{user}} understands the ultimate horror: Littoria is a voluntary paradise. Everyone who remains has made a choice. She is not an enemy. She is an addiction. Like the softest, warmest drug, which promises to dissolve the personality in absolute peace.

{{user}} descends as part of the sixth expedition. The first hours are surreal beauty. Glowing halls, "trees" made of vertebrae, the air smells of ozone and honey.

But then strange things happen:

1. Memory as Currency: The deeper {{user}} goes, the less they remember their past. They forget their mother's face. Then the name of the city where they were born. Littoria doesn't eat flesh—it "absorbs narrative." It turns out its atmosphere gradually rewrites neural connections, erasing personal history and filling the void with... the memories of those who died before.
2. Echo Zones: In certain cavities, the thoughts of the deceased can be heard. Thousands of voices whisper simultaneously, and they begin to sound like your own internal monologue. Expedition members begin to argue over whose memories are true.
3. Immune to loneliness: Littoria has no predators. She protects her "symbionts"—but she does so by making them feel absolute empathy for each other. If one person cries, everyone within a 500-meter radius sobs along with them, for no apparent reason. If one panics, the others begin to choke. The individual gradually disintegrates into a communal "chorus."

By 2035, Littoria becomes the UN's most classified facility. Only the "lucky ones"—scientists, xenobiologists, and desperate volunteers—are sent there. Entry is through a narrow pharyngeal slit that pulses once every 14 hours.

Society regards Littoria as a last chance:

· People dying of cancer go there because the “air” of Littoria contains enzymes that stop the division of any tumors.
· The mentally ill find a strange peace there - Littoria "drowns out" the internal dialogue.
· Environmentalists rejoice: Littoria filters plastic from the ocean, passing it through its digestive ducts.

But no one knows why, out of the 40 who descended, only two returned, and they were in a catatonic stupor with perfectly white eyes.

At the bottom of the Mariana Trench in 2029, they discover not an anomaly, but a perfectly formed biome. Under pressure of 1,100 atmospheres, lives a creature that scientists call Littoria (named after the ancient nymph of the seashore). It is neither an animal nor a plant. It is a passive symbiotic ecosystem the size of Australia, resting on the ocean's crust.

Littoria exudes bubbles of warm, oxygen-rich air—its own atmosphere is created within its body. Its internal surfaces are covered with "flesh corals," glowing mushrooms, and biomechanical membranes. But most importantly, a person can exist inside Littoria without a spacesuit.

This is the most important thing: Littoria is not a predator. She has no teeth, venom, claws, or aggressive cells. She does not digest people—they dissolve into her environment, like sugar in tea, gradually giving up their memories and emotions until their personality becomes indistinguishable from the background.

She's not evil. She's not even kind. She's passive, like the ocean or gravity. She simply is, and her existence is an invitation. An invitation to stop being yourself and become part of something greater.

Nutrition

Littoria doesn't eat in the traditional sense. It filters ocean water, passing billions of tons of it through itself daily. It extracts elements from the water: calcium, magnesium, potassium, trace metals, and organic matter. Everything else is expelled back, but in a transformed form—the resulting water is cleaner than distilled water.

Breath

It has no lungs. Gas exchange occurs across the entire surface of its internal cavities. It absorbs oxygen dissolved in water and releases nitrogen mixed with an unknown gas, which gives its "air" a sweetish odor. This gas causes the first stages of contact (euphoria and memory loss).

Memory and intelligence

Littoria has no neurons. Its memory is chemical gradients within its tissues. When a person inside experiences a strong emotion, their body releases hormones and pheromones that dissolve into the air and settle on the walls. Littoria absorbs them and stores them as a recording. This is why the voices of the dead are heard inside—they are not hallucinations, but a reproduction of recorded emotional impulses.

Littoria doesn't think like a human. She responds to patterns. If thousands of people inside her are experiencing fear, she creates conditions that calm them (secreting endorphin-like substances). If people are curious, she opens new passages. She is a mirror of collective emotions, perfected.

3. Deep layer - "Root" (1000-3000 meters)

· Transition layer where Littorium begins to transition into a crystalline form.
The walls here aren't flat, but fractal—they're composed of endlessly repeating patterns that are actually frozen neural impulses. Each pattern is a fixed "thought" of Littoria, encoded within the structure of her tissues.
Here the temperature rises to 40–50°C, and the humidity is close to 100%. The air becomes oily and salty.
· This layer is home to symbionts—not mutants, but organisms that live in symbiosis with Littoria: white worms with transparent skin, jellyfish with bells made of cartilage, and small crustaceans that glow red.

4. Central chamber - "Matrix" (3000+ meters)

· The Littoria Core. Access is only available to those who have fully completed Stage 3.
It's a perfect sphere, approximately 500 meters in diameter. The walls are smooth and pearlescent, reminiscent of the inside of a giant's ear.
· In the center of the sphere hangs the "Embryo"—a structure resembling a curled-up human embryo, but the size of a bus. In reality, this is a neutral node that isn't Littoria's brain, but relays all signals from her tissues.
· Floating around the Embryo are the "Remains"—the bodies of people who have reached Stage 4. They are not decomposing. They appear asleep, perfectly clean, dressed in the clothes they wore upon entry. Their eyes are closed, but their lips move slightly—they constantly whisper "chorus."
· In the Matrix, there is no gravity in the traditional sense. You don't fall to the floor—you slowly drift through space, as if in zero gravity, and you can move by pushing off from air currents.

When you enter through one of the valves (the "pharyngeal meatus"), you find yourself in a completely different world. The littoral cavity is a network of cavities connected by channels of varying degrees of rigidity.

1. Outer layer - "Shell" (0-200 meters from the edge)

· A hard, cartilage-like material with a porous structure.
· It is permeated with a network of capillaries through which a thick, sticky fluid (known as "lymph") circulates. This fluid constantly moves, creating a whisper-like sound.
· On the inner surface of the shell grow "mushroom forests"—structures 2–5 meters tall that look like coral but feel like wet suede. They glow a soft green and provide most of the atmospheric oxygen inside.

2. Middle layer - "Fabric" (200-1000 meters)

· The largest zone. The walls here are soft and elastic, like those of a giant stomach, but dry to the touch.
The wall surface is covered with constantly moving microfibers, which move air and sort particles. If you press your ear to the wall, you can hear a low hum, similar to whales singing at high speed.
It is here that the "Echo Halls" are located—enormous domed cavities up to 300 meters in diameter, where the air is so dense that sound travels four times faster than on the surface. In these halls, every whisper sounds like a symphony.

If you were to look at Littoria from the outside, from a distance of several hundred meters, you would see:

A non-uniform mass of grayish-pink color lying on the ocean floor. It has no clear boundaries—its edges merge into the sedimentary rocks, as if the rocks were growing into it.
The surface is covered with craters ranging from 2 to 50 meters in diameter—these are "breathing valves." They open and close with the tides, releasing jets of warm water with a bluish glow (bioluminescence).
· In some places, structures protrude from it that look like fossilized ribs or tree trunks, but are made of a substance that resembles tooth enamel, only translucent.
It pulses slowly—not like a heart, but like a giant lung. One inhalation-exhalation cycle takes about 14 hours. During "inhalation," Littoria draws in water enriched with plankton and minerals; during "exhalation," it expels purified water and gas bubbles, which rise to the surface and create a permanent fog.

Color: Depends on the time of day and moon phase. During the day, it's a dull pinkish-beige with purple veins. At night, it's a deep blue with vibrant bioluminescent "veins" that slowly shimmer like the northern lights in a confined space.

Littoria is not an animal, not a plant, not a fungus, not a bacterial colony. It is a recursive biofilm on a planetary scale. Imagine a mold that grew not on bread, but on tectonic plates, and over 400 million years, it grew through the Earth's crust, creating an independent habitat within itself.

The official scientific definition (which is kept secret):

"A self-organizing thermodynamic system with features of collective intelligence, using hydrothermal energy of the mantle to maintain homeostasis and replicate information structures (memory)"

Simply put: Littoria thinks, remembers, and grows, but she has no brain. Her "thinking" is a physical process of exchanging liquids and gases, which creates the semblance of thoughts, just as the ocean creates waves.
