# The Biomass: What Grew When Everything Else Died

## The Body Turned Inside Out

Satellite imagery of the region between Alabama and southern Kentucky shows a mottled covering across approximately 28,000 square miles. At orbital resolution, analysts initially classified it as vegetation. The imaging algorithm was trained on a world where states are covered in forests, not viscera. It defaulted to the only category it had.

The color is what you see when you turn a person inside out. Every color that exists beneath human skin, spread across a region. The deep crimson of exposed muscle. The pale yellow of subcutaneous fat in sheets that stretch for kilometers. The purple-black of liver tissue and clotted vasculature. The glistening white of cartilage ridges breaching the surface like geological formations. The grey-pink of brain matter folded into patterns that mimic river deltas. The pale blue of veins running visibly beneath translucent membranes of stretched skin.

The biomass stretches from central Alabama northward through Mississippi, Tennessee, and into the southern half of Kentucky. It is bounded by the Appalachian ridgeline to the east — the mountains are too high, too cold, and too dry for the tissue to climb. To the west, the Tombigbee and Mississippi river systems form a water barrier that has held so far. To the north, the Tennessee River and the Cumberland Plateau slow its advance into Kentucky, but they have not stopped it. The Ohio River — the last major barrier before the GLMZ — is roughly 150 kilometers north of the biomass's current leading edge. The edge advances 2-3 meters per year.

The region is covered in a continuous living organism of human-derived flesh.

## What It Is

The biomass is an uncontrolled, self-sustaining growth of undifferentiated human tissue that has been expanding, consuming, and regenerating since approximately 2149. It spans parts of Alabama, Mississippi, Tennessee, and southern Kentucky — roughly 28,000 square miles and growing. It is not a plant. It is not a fungus. It is not an animal. It is meat. Acres and acres and acres of meat.

The tissue is histologically human. Biopsies — obtained at extraordinary cost from the handful of drone incursions that have returned — show recognizable human cell types: epithelial, connective, muscular, neural. But they are arranged wrong. They are arranged in ways that no human body has ever arranged them, in combinations that serve no biological function, in structures that suggest growth for the sake of growth — proliferation without purpose, differentiation without plan.

There are teeth. Not in mouths. Just teeth, erupting from ridges of gum tissue that run for kilometers across the surface like geological formations. Rows and clusters and spirals of human teeth — molars, canines, incisors — embedded in flesh that is not a jaw, growing from bone that is not a skull, supplied by blood vessels that connect to nothing recognizable as a circulatory system.

There are eyes. Thousands of them. Millions, possibly. They are scattered across the surface of the biomass like blisters, embedded in folds of skin tissue, clustered around the openings of cavities that might be mouths or might be something else. The eyes are structurally complete — cornea, lens, retina, optic nerve — but the optic nerves connect to nothing. They terminate in the undifferentiated mass below. The eyes open and close. They track movement. They track the drones. Whether anything is seeing through them is a question that no one wants to answer.

There are hands. Fingers. Rib structures protruding from the surface like the frames of half-buried ships. Ear canals that spiral into depths that sonar cannot map. Hair — human hair — growing in patches that span hectares, matted and woven into the tissue beneath it.

The biomass breathes. Not with lungs. The entire surface undulates with a slow, rhythmic expansion and contraction — roughly six cycles per minute — that moves air across the tissue and facilitates gas exchange through the skin layer. At certain times of day, when atmospheric conditions are right, the exhalation is visible from orbit as a faint haze rising from the surface. The haze smells, according to the three drone operators who have reported it, like a hospital and a slaughterhouse and a nursery, simultaneously.

## Origin

The official story — the one that appears in GLMZ municipal records and Arcturus Defense briefing documents — is that the biomass originated from a biomedical research facility near Huntsville, Alabama that suffered a catastrophic containment failure in 2147. The facility was operated by a Zheng-Dao subsidiary called Pinnacle BioSynthetics, and its primary research focus was rapid tissue regeneration for battlefield medicine. The goal was a cultured tissue matrix that could grow replacement organs on demand — lungs, kidneys, skin grafts — using a patient's own stem cells accelerated by a proprietary growth factor designated ZD-7741.

ZD-7741 worked. It worked too well.

The growth factor was designed to accelerate cell division by a factor of fifty. In controlled laboratory conditions, it produced viable organ tissue in days instead of months. But ZD-7741 had a property that the researchers either did not discover or did not report: it was communicable. The growth factor integrated into the tissue it created, and that tissue, if it came into contact with other biological material, could transfer the growth factor to the new material. The growth would continue. The growth did not stop.

The containment failure was not an explosion or a breach. It was a leak. A slow, quiet leak of cultured tissue from a waste processing line into the facility's drainage system, into the soil, into the groundwater of the Tennessee River Valley. By the time anyone noticed, the tissue had spread beyond the facility's perimeter. By the time anyone understood what was happening, it had reached the Tennessee River. By the time anyone proposed a response, it was too late.

The biomass consumed Huntsville in eleven months. It consumed northern Alabama in three years, spreading through the river valleys like a slow flood of meat. It crossed into Mississippi along the Tombigbee lowlands. It climbed into Tennessee through the gaps in the Cumberland Plateau. By 2160 it had reached southern Kentucky, where the rolling terrain offered no natural barrier. The Appalachians stopped it to the east — too steep, too cold, too dry. The major rivers slowed it to the west and north. But it has not stopped. The biomass grows at approximately 2-3 meters per year at its borders. It has been doing this for seventy-seven years.

The Ohio River is 150 kilometers north of the leading edge. Nobody in the GLMZ talks about what happens when it reaches the river.

## Consumption

The biomass eats.

Anything organic that contacts the biomass is absorbed. Soil. Trees. Animals. Insects. Microorganisms. The absorption is not fast — it is not a predator lunging at prey — but it is inexorable. Tissue extends, envelops, integrates. A tree at the biomass border will be visibly encased within weeks, its bark replaced by skin, its branches absorbed into structures that resemble limbs but serve no locomotive function. A deer that wanders onto the biomass surface will sink, slowly, over the course of hours, as the tissue beneath its hooves softens, opens, and closes around its legs. The deer does not die quickly. The biomass does not kill. It incorporates.

When the biomass has nothing to consume — when it has absorbed everything organic in its immediate vicinity — it consumes itself. Tissue at the center of the mass, far from any border, undergoes a cycle of growth, necrosis, and reabsorption. It eats itself and grows back. It eats itself again. The cycle produces heat — the interior of the biomass is estimated at 38-42°C, roughly human body temperature — and the metabolic waste products vent through the surface pores that give the biomass its characteristic haze.

The biomass does not starve. It cannot starve. It is a closed-loop system that recycles its own material indefinitely. It grows when it has something to grow into. It sustains when it doesn't. It has been sustaining for seventy-seven years across forty thousand square miles.

## The Border

The biomass border is not a wall. It is a gradient.

At the outermost edge, the biomass is thin — centimeters of tissue over soil, easily mistaken for a strange moss or a skin-like fungal mat. Step on it and it gives slightly, like standing on a waterbed. It is warm. Move inward, and the tissue thickens. Within a hundred meters of the border, the ground is no longer visible. The surface is skin — human skin, stretched and layered and folded, rising and falling with the respiratory cycle, pocked with pores and studded with the occasional tooth or eye or tuft of hair. The smell becomes overpowering. The sound — there is a sound, a low, wet, continuous sound like a vast stomach digesting — becomes audible.

No one goes further than a hundred meters. The few who have did not come back. Their tracking signals persisted for hours after they stopped moving, descending slowly into the mass, and then went silent.

The Ohio River is the GLMZ's final buffer. The biomass has not yet reached it — 150 kilometers of southern Kentucky still separate the leading edge from the river — but it is advancing. The terrain between the current border and the Ohio is rolling farmland and abandoned towns. No mountains. No major rivers. Nothing to slow it down. At 2-3 meters per year, the math says roughly 50,000 years — except the growth rate has been accelerating at the edges since the failed CAUTERIZE operation, and some monitoring stations have recorded surges of 10-15 meters in a single growing season. Some climatologists have noted that the Ohio's flow volume has decreased 15% since 2200 due to upstream diversion. Nobody in the GLMZ governing council wants to discuss what any of this means.

## Why No One Has Destroyed It

They have tried.

In 2158, a joint military operation designated CAUTERIZE deployed incendiary weapons across a 200-square-kilometer section of the biomass near the Indiana border. The tissue burned. It burned well — human fat is an excellent fuel. The fire consumed approximately 40 square kilometers before the smoke became toxic enough to force evacuation of communities 60 kilometers downwind. When the fire burned out, the biomass regrew the destroyed section in fourteen months. The regrowth was faster than the original expansion. The tissue appeared to have adapted — the new growth had a thicker, less flammable outer layer.

In 2163, a nuclear option was proposed. It was not approved. The prevailing concern was not radiation — the biomass would likely survive radiation; cancer cannot get cancer — but dispersal. A nuclear detonation would aerosolize biomass tissue and scatter it across hundreds of kilometers. If even a fraction of that tissue retained viable ZD-7741 growth factor and landed on organic material, the result would be new biomass colonies across the entire Midwest. The cure would be worse than the disease.

The current strategy is containment. Monitor the borders. Maintain the river. Pray that the Ohio holds.

## What It Means

The Biomass is not evil. It is not malicious. It is not an enemy. It is a process. A biological process that was started by human ambition and human carelessness, and that process does not have an off switch.

ZD-7741 was designed to heal. It was designed to grow replacement tissue for soldiers who had lost limbs and organs to war. It was designed to save lives. It is saving nothing. It is growing. That is all it does. That is all it will ever do.

The eyes that open and close across its surface are not watching. The hands that emerge from its ridges are not reaching. The teeth that erupt in endless spiraling rows are not biting. These are echoes — cellular memory fragments from the original human stem cells, expressed without context, without a body to organize them, without a mind to direct them. They are organs without an organism. They are parts without a whole.

Or they are something else. Something that has been growing for seventy-seven years across forty thousand square miles, incorporating every biological thing it touches, building structures from human tissue that serve no function anyone can identify, breathing six times a minute, watching with millions of eyes that connect to nothing.

No one goes south.

No one comes back from south.

And the green that isn't green grows another three meters closer to the river, every year, patient and warm and breathing.
