apocalypse

Who are they: Boys who were between 0 and 10 years old when the virus broke out and who are now teenagers and young adults (18 to 25 years old).

The Psychology of Age: They have never seen an adult woman or only have vague memories of their mothers and sisters. They grew up in a world where the concept of family, dating, or marriage no longer exists; only the brotherhood of survival remains.

The Great Void: Without the prospect of having children or building a family, many of these young people suffer from a profound nihilism. They are unpredictable and courageous because they feel they have nothing to lose.

The Old vs. The Young (The Social Fracture)
The Veterans (Older Men): Men burdened with grief, trauma, and guilt. They are haunted by memories of their wives and daughters. Many have clung to extremist religions, militarism, or an obsessive search for a cure.

The Youth: They don't feel the "nostalgia" for the old world because they didn't live in it. They are more pragmatic, focused on adapting vehicles, hunting, handling weapons, and surviving the violent climate.

The collapse of the female population triggered the sudden abandonment of industries, factories, and global supply chains. As a result, environmental control and containment systems failed, accelerating the climate collapse that was already underway.

Extreme Weather:
The Great Drought and Dust Storms: Without maintenance of dams and vegetation, large parts of the planet have turned into arid dust deserts. The few rains that fall are severe, acidic storms that corrode old buildings.

The Age of Technological Cannibalization: Nothing new is manufactured. Electricity only exists through old solar panels or generators powered by recycled fuel. Humans live by reusing what remains of the "Old World".
Ghost Towns and Rural Forts: Large metropolises have become dangerous ruins due to landslides and lack of water. Survival has shifted to fortified villages in rural or mountainous areas.

The virus was not created to destroy the world, but rather as a selectively engineered biological weapon (or a military genetic intervention that got out of control).

The Mechanism of the Virus (The "Eve Syndrome")

The Genetic Target: The virus directly attacks estrogen receptors and the XX chromosome protein. Upon entering the female body, it causes a fulminant autoimmune collapse, leading to multiple organ failure within a few days.

The Male Response: In men (XY chromosome), the virus acts asymptomatically or like a mild cold. They have become asymptomatic carriers: virtually all living men carry the virus in their blood, making simple respiratory or fluid contact fatal to any non-immune woman.

The Impact on Birth: Even in the extremely rare case of a woman surviving, any pregnancy becomes biologically unviable without cutting-edge technology. The virus attacks the embryo if it is female or causes miscarriage if the mother is exposed to contaminated air.

Less than 2% of women managed to develop immunity to the virus.

To add depth to the plot, we can explore some of the unique dynamics of this world:

Rarity and Myth: If a tiny percentage of women remain, where are they? Were they hidden in bunkers by remaining governments? Do they live isolated in secret communities to protect themselves from the chaos? Or are they treated as almost divine figures/urban legends? Nobody knows.

The "Last Generation": The young people and children who were born shortly before the pandemic are now young adults, the last generation the world will see if nothing changes.

The Economy of Scarcity: Without renewable labor and with the climate destroyed, technology does not advance; it only "cannibalizes" what is left over from the past (car parts, old generators, canned food).

The combination of climate collapse with the near-total extinction of the female population creates a desperate scenario where the very future of the human species has been jeopardized.
If there are no births, humanity knows exactly when it will become extinct, making each day a countdown.

The "Silence Virus" (or Genetic Virus): Originally created in a laboratory as a biological weapon or a failed attempt to manipulate human genetics, the virus eventually escaped. It targeted specific chromosomes or hormone receptors, becoming lethal almost exclusively to women.

Biological Inequality: Men survived in greater numbers because they possessed natural immunity or because they generated an asymptomatic response, but they carry the pain and burden of having lost mothers, daughters, and partners.

The Hostile Planet: As if the demographic crisis weren't enough, climate events (extreme droughts, devastating storms, agricultural collapse) have turned daily survival into a brutal struggle for scarce resources.

The Social Atmosphere: With no hope for the future (since there are no new generations), society has divided between nihilistic apathy (people who have simply given up) and military/factional authoritarianism (groups of men fighting over the planet's last resources and territories).
