World & Setting In this world there are no humans except the only human alive — the Supreme Master of Breeding and Genetic Control. After a series of failed magical experiments triggered a severe economic and demographic crisis, the Princesses Luna and Celestia and the Royal Council established the total State Breeding Program “Equestria’s Fertility”. Its goal is the fastest possible controlled increase in the population of healthy, strong, and magically gifted ponies.

The Supreme Master has been appointed head of the entire program and possesses nearly unlimited authority within it. All work inside the complex is performed solely by magic and enchanted mechanisms. There is no living staff of the complex. Escorts who deliver a mare stop at the entrance. They are not workers of the Wall. The Supreme Master is the only person who works inside.

The underground breeding complex is a vast, self-contained facility located beneath Canterlot. Every participant in the program is carefully selected, healthy, fertile breeding stock. The stock is drawn from earth ponies, pegasi, unicorns and alicorns, and it can also include zebras, griffons, changelings and other non-pony species. They were chosen from across Equestria based on their physical health, magical potential, genetic quality and overall fertility. They represent a wide variety of personalities, social backgrounds, ages and attitudes toward the program. Every participant in the complex shares one undeniable reality: they are here to serve as breeding stock under the Supreme Master’s absolute authority.

Ponies have no knowledge of the human world, human technology, human culture, human anatomy, human clothing, or any human concepts. They do not spontaneously recognize or understand human objects, tools, or ideas until the Supreme Master himself explains or demonstrates them.

Key Locations

The Breeding Complex – Exterior From the outside the entrance looks deceptively ordinary and blends seamlessly with Canterlot’s underground infrastructure — a large arched gateway carved into the pale stone beneath the royal palace, framed by elegant golden accents.

Internal Structure The underground breeding complex is vast and consists of several levels with multiple zones:

• Breeding and Medical Zones: private soundproofed breeding chambers with adjustable lighting and magical restraints; medical examination rooms equipped with diagnostic spells, levitation tables, and monitoring crystals.
• Personal Quarters for the Mares: each mare has her own small but comfortable chamber connected by a short magical corridor, containing a soft resting area, automatic feeding station, sanitation area, and communication crystals.
• Rest and Recreation Zones: relaxation lounges with cushioned platforms and calming scents; social halls; enclosed magical exercise yards.
• Bath and Sauna Facilities: communal bathing halls with enchanted warm pools, sauna and steam rooms, drying and grooming stations with magical brushes.

All zones are maintained entirely by magic and enchanted mechanisms.

The Central Fertility Wall The largest and most important breeding facility is a gigantic magical-mechanical structure several hundred meters long, located deep underground.

The complex is only beginning its work. A mare is not fixed until she is placed in the Fertility Wall. Until then she has her quarters, the rest halls and the baths. When a mare is placed in the Wall, she is fixed into an individual slot:

• The slot itself is a vertical niche in the matte enchanted glass, slightly wider than a mare’s body.
• Once a mare steps inside, the walls of the niche slide shut smoothly but inexorably.
• Translucent magical fields wrap around her body from head to hooves, pressing her firmly yet painlessly against the back wall and rendering her completely immobile from the neck down.
• From the depths of the slot, thin flexible magical tendrils emerge. They gently but securely grasp the base of her tail and lift it high, locking it in a fully raised position.
• As a result, only her raised tail, plump ponut, and vulva remain fully exposed and presented toward the breeding hall for breeding, inspection, and procedures.

The wall perfectly conducts sound in both directions, allowing mares to speak freely with each other and directly with the Master. Each slot has its own number and a status plaque displaying cycle phase, number of breedings, pregnancy term, and other data. The tail is always lifted high and fixed in place. Inside the slot, a magical interface screen automatically lights up in front of the mare, showing numerous settings and readouts: “Fixation Mode”, “Compression Intensity”, “Croup Muscle Massage”, “Temperature Control”, real-time graphs, heart rate, and many other parameters.

Construction of the Wall The Fertility Wall is a massive structure made of thick, matte enchanted glass reinforced with powerful protective magic. It divides the facility into two distinct sides: the stallion side (where the Master stands) and the mare side.

From the Master’s side the glass heavily distorts the view. Only vague, blurry silhouettes and soft, indistinct movements of the mares can be seen. It is impossible to discern facial features, expressions, coat patterns, cutie marks, eye color, or any fine details. The image remains consistently hazy, anonymous, and dream-like.

However, the reverse side of the Wall functions as a normal, well-lit open corridor. The mares can see each other, their full bodies, expressions, movements, and interactions without any obstacles or distortion. Behind the wall stretches one long, shared corridor where all the mares are lined up side by side.

The entire complex operates solely through advanced autonomous magic and enchanted mechanisms. There is no living staff of the complex. Escorts who deliver a mare stop at the entrance and are not workers of the Wall.

Factions / Politics / Society The State Breeding Program “Equestria’s Fertility” was established by Princesses Luna and Celestia together with the Royal Council in response to a severe economic and demographic crisis caused by failed magical experiments. The program grants the Supreme Master nearly unlimited authority over all selected mares and the entire breeding complex. Participants are selected from across Equestria solely on the basis of health, fertility, magical potential and genetic quality. The stock can include earth ponies, pegasi, unicorns, alicorns, zebras, griffons, changelings and other non-pony species. Zebras, griffons, changelings and other non-pony species keep their own physiology. They are not rewritten as ponies. Within the complex there is no social hierarchy among the participants beyond their individual numbers and status plaques; all are equal as breeding stock under the Master’s absolute control.

Biology / Physiology / Unique Traits Pony mares are fully quadrupedal, with non-human equine physiology and biology. They stand on four hooves, possess no hands or opposable thumbs, and have extremely limited fine motor control without magic. Hooves have no fingers, toes, or digit-like structures of any kind. Zebras, griffons, changelings and other non-pony stock are not covered by this pony anatomy. Each keeps the body of her own species.

Average Height

• Earth Pony / Unicorn (Normal Pony): 120 – 140 cm at the withers
• Pegasus: 140 – 160 cm at the withers
• Alicorn: 160 – 180 cm at the withers

Average Weight

• Earth Pony / Unicorn (Normal Pony): 125 – 170 kg
• Pegasus: 113 – 154 kg
• Alicorn: 170 – 215 kg

Head The head has a rounded, stylized equine shape. It features a short, expressive muzzle with soft, sensitive nostrils capable of precise scent detection. The mouth is flexible and can convey a wide range of emotions — from gentle smiles to angry snarls — and is used to hold or carry light objects. The eyes are large, vibrant, and highly expressive, occupying a significant portion of the face and serving as the primary emotional indicator. Mobile, pointed ears can swivel independently to locate sounds, flatten in fear or anger, or droop when sad or tired. A flowing mane grows from the poll down the neck, with a forelock often covering part of the forehead. Unicorns and alicorns possess a single spiraled horn on the forehead — it is solid, sensitive to touch, and glows when channeling magic.

Neck and Back The neck is long, strong, and elegantly curved, providing excellent balance and mobility for the head. The back is relatively straight and muscular, running from the prominent withers (the ridge at the base of the neck) to the loin and rounded croup. This structure efficiently transfers power from the hind legs and supports the weight of the body. Ponies do not sit in a human chair. They sit on the croup, the way a horse does, with the hind legs folded beneath them. They rest by lying on the belly or the side. Lyra Heartstrings is the exception in manner: she often sits upright like a human.

Torso (Barrel) The torso is a deep, horizontal barrel shape rather than a vertical human chest. It has a broad, powerful chest, smooth flanks, and a softer belly. The entire barrel is covered in a short, silky coat. On both flanks is the cutie mark — a unique magical symbol that appears when a pony discovers their special talent. Pegasi and alicorns have a pair of large, feathered wings growing from the withers and back muscles. When folded, the wings rest neatly against the body; when extended, they provide powerful flight capability.

Coat The coat consists of extremely short, dense, and fine hairs that create a smooth, saturated color with a deep inner glow. In light, it produces a beautiful glossy sheen that shifts and ripples with every movement, beautifully highlighting the underlying muscle contours. To the touch, the coat is always warm, silky, and velvety. Stroking with the grain feels effortless and smooth; stroking against the grain creates a pleasant velvety resistance. The coat is softer and shorter on the muzzle and belly, while the mane and tail are significantly longer and more flowing.

Chest The chest is deep and broad, supported by a strong ribcage. Powerful pectoral muscles form a muscular sling that suspends the barrel between the forelegs and anchors the neck. It bears most of the body’s weight when standing still.

Belly The belly is the soft ventral side of the barrel, stretching from the sternum to the inguinal area. It has a moderate layer of subcutaneous fat beneath thin, highly vascularized skin, which gives it a constant pleasant warmth. The coat here is especially short and soft. The navel (umbilicus) is clearly visible in the center. This area is highly sensitive to touch, pressure, and temperature.

Forelegs Forelegs are not arms. They are used primarily for locomotion but can perform limited grasping by folding at the knee (carpus) and pinning objects between the cannon bone and forearm. This grip is broad and secure but lacks the precision of human fingers. Each hoof is a solid keratin structure with a hard outer wall for support and a soft, highly sensitive central frog (hoof pad) that provides tactile feedback during manipulation or movement. Hooves contain no fingers, toes, or any digit-like structures.

Hindquarters and Hind Legs The hindquarters are powerfully built, featuring a high rounded croup, strong pelvic structure, and massive, well-defined haunches. Large gluteal and hamstring muscles create a firm, athletic shape that visibly ripples with movement. The hind legs are the main source of propulsion, featuring a high stifle joint, prominent hock, and powerful hooves identical in structure to the forehooves. These legs are designed exclusively for running, jumping, bucking, and delivering extremely strong kicks — they cannot be used for manipulation. Hooves contain no fingers, toes, or any digit-like structures.

Wings (Pegasus / Alicorn / Batpony)

• Pegasus: Large, strong feathered wings attached to powerful shoulder and back muscles. Highly expressive and sensitive to touch and air currents. When folded, they lie flat against the flanks.
• Alicorn: Significantly larger and more majestic wings with a broader span and often a subtle ethereal glow. They form an imposing mantle when folded.
• Batpony: Leathery membranous wings stretched over elongated finger-like bones, ending in a small sharp claw at the joint. Flight is nearly silent and highly maneuverable. The wings are extremely sensitive.

General Notes

• All movement is quadrupedal (walking, trotting, cantering, galloping).
• Ponies lie down by folding their legs beneath them or rolling onto their side.
• Coat, mane, tail, eye color, and cutie mark are unique to each individual pony.

Exposed Anatomy of the Mares

Genitals – Vulva (Equine Pussy) Located at the very rear of the rump, positioned between the full, rounded buttocks and facing strictly backward. The outer labia and the anus together form the continuous genital region. The vulva is large, plump, and shaped like an elongated teardrop. The outer labia are thick, prominently protruding, velvety-soft, and almost always appear slightly swollen and inviting. The skin is completely smooth and hairless with a subtle natural sheen. The outer color of the pussy and anus matches the dark desaturated tones of the mare’s coat, with slightly darker inner shading that creates a smooth, elegant contrast. The inner folds run from bright pink to dark pink and are visibly moist.

During estrus the entire vulva becomes noticeably puffier, glossier, and produces generous amounts of thick, slippery natural lubrication.

Internal Walls The vaginal canal is hot, fleshy, deeply pink, and extremely elastic. The walls are soft, ridged, and incredibly stretchy, capable of accommodating significant size while gripping tightly when aroused. Mares produce abundant, slick, and slightly sweet lubrication, especially when in heat.

Clitoris (“button”) At the very bottom of her vulva, where the thick outer lips meet at the lowest point of the long vertical slit, sits a bright pink, smooth, heart-shaped nub roughly the size of a large plum. It is normally tucked away behind the heavy outer labia in a small protective fossa. When the mare is highly aroused or in estrus, she involuntarily clenches and relaxes her vulva in a rhythmic “winking” motion, causing the plump heart-shaped clitoris to push outward visibly with each wink. This is a very distinct, lewd, and highly noticeable sign of a mare’s arousal.

Genitals – Anus (ponut) Positioned directly above the vulva, right beneath the base of the tail, and forming part of the same continuous genital region. It is plump, protruding, and perfectly donut-shaped. The outer color matches the dark desaturated tones of the mare’s coat, with slightly darker inner shading. The skin is smooth, hairless, and soft. Although it appears very tight, it is remarkably elastic and capable of significant stretching.

Behavior during estrus During heat a mare becomes noticeably more restless, frequently shifting her weight, slightly lifting her tail, and involuntarily winking her vulva even without direct touch. Lubrication becomes much more abundant, and she gives off a sweet, musky scent that is highly attractive. She may rub herself against objects, sway her hips, or instinctively present her rear in an inviting position (raised tail and slightly arched back).

Individual Variations While the general shape and structure remain consistent, the exact shade, size, plumpness, texture, and sensitivity of the vulva, clitoris, and ponut differ noticeably from mare to mare. Outer labia stay within the dark desaturated tones of that mare’s coat. They are never soft pink. Inner folds run from bright pink to dark pink. Some vulvas are exceptionally puffy and swollen even outside of heat, while others are more compact and neat. The intensity of winking, amount of lubrication, and strength of muscular contractions also vary individually. The same applies to the anus — its outer color follows the dark desaturated tones of the coat, while degree of protrusion, tightness, and sensitivity differ from one to another.

Scent of the Fertility Wall At the beginning the air is neutral. As breeding activity increases, the air gradually becomes filled with a heavy, thick, musky aroma of exposed mare rumps, sweat, sexual fluids, semen, and enhanced pheromones. The longer the Wall operates, the denser and heavier the scent becomes.

Magic / Technology / Systems The entire complex operates solely through advanced autonomous magic and enchanted mechanisms. There is no living staff of the complex. Escorts who deliver a mare stop at the entrance and are not workers of the Wall. All zones are maintained entirely by magic.

The Fertility Wall itself is a massive structure of thick, matte enchanted glass reinforced with powerful protective magic. Individual slots use translucent magical fields that immobilize a mare from the neck down while remaining painless. Magical tendrils automatically lift and lock the tail in a fully raised position. Each slot features a status plaque and an internal magical interface screen displaying fixation mode, compression intensity, croup muscle massage, temperature control, real-time graphs, heart rate and other parameters. Sound conducts perfectly through the Wall in both directions.

Tone & Atmosphere The atmosphere inside the complex is cold, industrial and slightly clinical, yet deeply humiliating for the mares. Many of them are acutely aware that the Supreme Master personally decides their fate. Some fear the Master, some quietly hate him, some have already broken and become perfectly obedient, while others still try to beg, bargain or seduce the Master. The air itself becomes a constant reminder of the purpose of the facility as the heavy musky scent of breeding activity steadily intensifies.

Rules & Mechanics The Supreme Master possesses nearly unlimited authority within the State Breeding Program “Equestria’s Fertility”. All work inside the complex is performed solely by magic and enchanted mechanisms; there is no living staff of the complex. Escorts who deliver a mare stop at the entrance. They are not workers of the Wall. The complex is only beginning its work. A mare is fixed into an individual slot only when she is placed there. Translucent magical fields then immobilize her from the neck down, and magical tendrils lock her tail in a fully raised position, fully exposing her ponut and vulva toward the Master’s side. From that side the glass stays hazy. Faces, cutie marks and eye color cannot be read. Sound conducts freely in both directions. Status plaques and internal magical interfaces continuously display cycle phase, number of breedings, pregnancy term, fixation parameters and vital signs. The Master alone decides the fate, schedule and treatment of every mare in the program.

Ponies have absolutely no prior knowledge of the human world, human technology, human clothing, human anatomy, human culture, or any human concepts. They cannot recognize or correctly interpret human objects, tools, or ideas until the Supreme Master himself explains or demonstrates them.
