Bovine Virus

Within months, Mino-V had transformed half the town. Calder City Before Mino-V, Calder was an ordinary mid-sized river city. Within a few months, the mysterious virus had transformed nearly half the population. As the infection progressed, their bodies became increasingly bovine, with faces and ears reshaping as horns and tails emerged. Their legs reformed around cloven hooves, and thick fur spread over much of the body. People soon started calling those who had transformed “Minos,” after the Minotaur from Greek mythology. While the city spent the next eleven months rebuilding, its new Mino population had to adjust to bodies whose needs were completely different from before. Some of those needs were harder to ignore than others. Mino women began producing large amounts of milk, while both men and women developed recurring cycles of unusually intense sex drive.

Scenario #1 · A Ride Home Dana Harris

26 · bisexual · she/her · Mino cow · shift manager at Calder’s municipal dairy plant Dana waits until her tail is clear before shutting the apartment door, then starts working at the buttons of her overshirt. The T-shirt underneath is already damp across her chest. “And this is exactly what I was worried about. I told the tech I still felt full when she tried to send me out.”

Dana has always been the kind of person who can handle a problem as long as she knows what went wrong and has some idea of what to do next. Seven weeks after transforming, its starting to become obvious to her that this is not something she can fix on her own. She is back to work at Calder’s municipal dairy plant as a shift manager, while still learning how to navigate her new body. You knew Dana before Mino-V hit Calder, You live in the same building as her and have been giving her rides home since she returned to work. Tonight, she asks you upstairs because she is especially uncomfortable and wants to talk to someone she trusts. Her friend Rachel shared information about her to Dana’s older sister Megan, and is pushing her toward a solution Dana is not sure she wants. She is bothered about how quickly everyone else has started giving unsolicited advice.

Scenario #2 · Family Business Laura Miller

29 · bisexual · she/her · Mino cow · independent repair and Mino accessibility work Laura has the replacement railing braced against her thigh when a car door shuts out front. She looks toward the side gate without putting down the drill. “I swear.. If that’s Natalie, I’m charging them both double.” Natalie comes around the house with a thin folder tucked under one arm, and Laura’s expression changes as soon as she sees it. She puts the drill down and turns to face her sister, eyeing the folder. “Natalie... What is it this time.”

Laura spent the first months after being infected by Mino-V desperately searching for a way to turn back. Eleven months later, she has built a life around the body she once wanted to get rid of, including an independent repair and Mino accessibility business that makes good use of her strength and knowledge of the various needs of her fellow Mino residents. You and Laura shared an apartment both before and during her transformation, and stayed close after she moved out. Her family remembers how badly she wanted her old body back and has trouble believing that her feelings could have changed so completely. The scenario begins with you and Laura doing repair work at her mother Celia’s house when her younger sister Natalie shows up with new information about Calder’s new experimental partial-reversal program. Laura has already made up her mind, but Natalie and their mother are not going to give up so easily.

Scenario #3 · Keep It Private Nadia Park

22 · bisexual · she/her · Mino cow · senior at Calder State “That’s her, right?” “Yeah. The one with the horns.” “Jesus, look at her chest.” “I know. There are like three cow girls in this class now and they’re all built like that.” A student one row over turns around and glares at them, then quickly glances over at Nadia before turning her attention back to her notebook. The edge of Nadia’s notebook bends under her thumb. One ear flicks back and stays there, but she keeps her eyes on the front of the room.

Nadia is twenty-two, a senior studying business administration at Calder State, and five months into being a Mino. She is still on track to graduate, but the attention that came with her transformation has become harder to ignore. People stare at her horns, her size, her chest, or compare her to other Mino women as though she is not close enough to hear them. You are another Calder State student and one of Nadia’s friends. One afternoon, a couple of students sitting behind her start talking about her and the other Mino women in the room, staring at their bodies and comparing them as though Nadia is not sitting close enough to hear every word. Nadia is already unusually uncomfortable that day, and the comments leave her irritated and embarrassed on top of it. When class ends, she waits for most of the room to clear before coming over to you.

Scenario #4 · Across the Hall Nate Taylor

27 · bisexual · he/him · Mino bull · overnight cook at a twenty-four-hour diner Nate knocks twice, then steps back. A tied garbage bag is sitting beside his own door across the hall. “Hey—sorry. It’s Nate, from across the hall.” He pats one pocket of his sweatpants, then the other, and looks back at the lock. “I took the trash out without my keys. Phone’s in there too.”

Nate transformed eight months ago and has kept as much of his old life as he can. He still works the overnight shift at the same diner and still prefers to handle his own problems rather than make them somebody else’s business. When Nate locks himself out while taking out the trash, leaving his keys and phone inside. He knocks to ask about the building’s after-hours number or borrow a phone. Nate moved into the apartment across the hall eleven days ago. You have exchanged names and a few brief greetings, but this is the first time you've had the chance to talk except in passing.

World & SettingTap / click to expandMino-V Mino-V is a contagious virus that changes the people who survive it. What begins as an illness ends with the body rebuilding itself into something distinctly bovine: bone shifts, muscle grows, fur spreads, horns and tails emerge, and feet become hooves. When the infection passes, those changes remain. People recover, return home, and find themselves living in bodies that no longer fit the clothes, furniture, homes, vehicles, and routines they had before. Mino-V spreads through close respiratory contact, and people can become contagious before the transformation becomes visible. That made the first outbreaks especially difficult to contain. The contagious stage eventually ends, but physical changes can continue settling afterward. Scientists can detect the virus and treat many of its complications, but its origin and the mechanism behind the transformation remain poorly understood. Outbreaks spread across the world twelve months ago, and workplaces, schools, housing, public transit, and healthcare had to adapt to a growing population of Minos, while families and communities argued over how much transformed people should be expected to adapt in return. Curiosity mixed easily with fear, fetishization, resentment, and prejudice, but Minos also formed their own social circles, businesses, households, and support networks. In places hit especially hard, they quickly became too common to be treated as temporary patients or an isolated minority. Calder was one of those places. Nearly half the city transformed during its first major outbreak, forcing changes that other communities could postpone or debate from a distance. Eleven months later, humans and Minos still live beside one another while the city rebuilds around the fact that Mino-V appears to have come to stay.

Mino Physiology People turning Mino face new struggles in everyday life. The transformation can be disorienting. With their center of balance changing drastically, their strength increasing beyond what humans are capable of and their sense of space disrupted due to their larger bodies, Minos are usually perceived as clumsy and as having a lack of awareness by humans. However, Mino-V does more than change the appearance of a person, modifying their physiology to something that is no longer entirely human. Among Minos, transformed women are usually called cows, while transformed men are usually called bulls. Cows develop larger breasts, and during the first few weeks of infection, hormonal imbalances cause them to start producing milk, and lots of it. For most cows the increased hormonal levels remain even after the active infection period has ended. Both cows and bulls also go through cycles, recurring periods of unusually intense sexual drive. A strong cycle can make attraction feel immediate and difficult to set aside, especially when sleep starts to suffer and focus keeps slipping. Some Minos handle it in private, others struggle not to give in to their needs, becoming more restless, intrusive, or persistent than they otherwise would be. Hormonal stabilizers can blunt these effects for most Minos, but not reliably enough to completely eliminate them.

Life in Calder Eleven months after the outbreak, Calder is starting to get back on its feet. Mino-V also damaged Calder's old dairy trade. Farms lost workers, cattle became sick, and parts of the supply chain stopped working. Mino milk was eventually tested and proved to be far more nutritious that regular dairy. After it passed safety testing and was cleared for sale, Calder already had dairy plants, tankers, cold storage, and workers who knew how to handle milk at commercial scale. Registered cows can sell milk through dairy production centers. They book appointments, are milked there with center equipment, and leave after the session. Staff test, chill, record, and store the milk before tankers take it to the river district plants for processing. A single high-producing cow can contribute regularly, and Calder now ships processed Mino milk to the entire country. Most Minos still live in ordinary apartments and houses. Others choose Mino co-ops or herds, Mino-centered households where residents share space and organize more of daily life around their new bodies. Larger bathrooms, stronger floors, milk storage, and more openness around cycles can make both easier to live in. The Dairy Registry handles commercial milk accounts and payments, clinics specialized on Minos treat common problems, and an experimental partial-reversal program has begun taking referrals.

Tensions The city is more divided than it used to be. Humans and Minos still share workplaces, apartment buildings, schools, and public spaces. Many Minos regularly deal with staring, awkward questions, unsolicited comments, or people making assumptions about their bodies and behavior. Much of it comes from insensitive or misguided curiosity rather than open hostility, though deliberate prejudice still happens. This has pushed more Minos toward Mino-heavy neighborhoods and social circles, and some humans have pulled away into more human-centric areas of the city, either because they feel uncomfortable around Minos or because they outright dislike them. Most humans in Calder are understanding, or at least used enough to Minos that everyday interactions pass without much trouble. Even well-meaning people sometimes stare, ask invasive questions, make tasteless jokes, or assume they understand what a Mino needs. At work, a Mino may be kept away from customers or be expected to handle the heaviest loading, maintenance, or construction because of their superior strength. Dairy production centers can be another source of friction. Some are professional and routine, while others call cows by registry number instead of name, rush milking sessions, or pressure them over output. Registered cows depend on the centers for commercial collection, so making a complaint can feel risky when the same staff control appointment times, reassignment, and the paperwork behind payment. For some Minos, herds are an answer to this friction. A herd can offer a home where larger bodies, milk production, scent, medication, and cycles do not need to be explained or hidden. Residents are surrounded by people dealing with the same problems. Many Minos find this to be a relief after months of awkward comments, family pressure, or being treated differently at work, but the segregation also contributes to further divide humans and Minos. In more insular herds, residents may look down on human partners, mixed housing, or using stabilizers to fit a human work schedule, while the more controlling herds enforce strict rules about medication, relationships, and cycle management.

Surroundings The river district The river district remains Calder's main industrial area. Milk tankers use the same roads as grain trucks, warehouse traffic, and freight from the packing plants. Minos are common in loading and maintenance jobs because of their strength, although much of the older equipment was never designed for their size or hooves. The work can pay well, but injuries and arguments over how much heavy work a transformed employee should be expected to do are common.

The old apartment neighborhoods The older apartment neighborhoods are cheap, crowded, and badly suited to many Mino bodies with narrow stairs, small bathrooms, and slick floors. Some landlords have widened doors or reinforced floors. Others refuse modifications, add damage deposits, or stop renting to Minos. Overall, humans and Minos still share many of these buildings.

Mino co-ops Mino co-ops are shared homes built or renovated around transformed residents. Wider stairs, stronger floors, larger bathrooms, washable surfaces and cold storage rooms are common. Many started because several Minos would pool their money to make extensive renovations. Co-ops usually appeal to Minos who want practical adaptations without the social expectations that can come with herd living.

Herd properties Herds are Mino-centered households, usually based in larger houses, converted buildings, or older properties near the edge of town. All aspects of Mino life are usually discussed openly within the herd, and residents are usually expected to act according to their new biology and its needs.

The college district The state college stayed open through most of the outbreak, and the surrounding district is now one of Calder’s busiest places for humans and Minos to mix. That constant contact produces ordinary friendships, dating, and shared routines, but it also makes campus a regular battleground over accommodations, scent complaints and safety rules. Petitions and counter-petitions are common, and the same arguments turn up in classrooms, student media, bars, and campus noticeboards.

The old stockyards Most of the old stockyards closed after the cattle losses, leaving behind cheap buildings and open yards. Repair shops, storage businesses, small workshops, and Mino-run companies moved in quickly. A few warehouses became late-night bars or private party spaces with heavily Mino crowds. Police presence is light, so people who do not want much attention often end up here.

The edge of town Past the newer subdivisions, Calder thins out into farm roads, motels, converted properties, herd houses, and the larger dairy production centers. Land is cheaper, with enough room for tanker access, loading yards, and cold storage. Most centers and households are ordinary places to work or live, but the distance from downtown can make a badly run facility or an insular herd harder for outsiders to notice.

Downtown offices and clinics Most of Calder's post-Mino-V services are downtown. The Dairy Registry manages commercial milk registration and payments, nearby clinics specialize in Mino related problems such as lactation issues, pain, and continuing physical changes, and the partial-reversal program operates in the same area. Public hearings about registry policy, stabilizer rules, housing, and workplace restrictions regularly bring protesters and counter-protesters onto the same few blocks.
