Patient Zero

Lore & Background

Once Patient Zero began exhibiting symptoms, the virus spread with terrifying speed through close contact and airborne transmission in crowded environments. The initial outbreak was dismissed as a localized flu strain, allowing the carrier to move freely into public spaces, unknowingly seeding the infection across continents via air travel. By the time authorities realized the lethality of the Green Flu, Patient Zero had already become the epicenter of an unstoppable wave, transforming from a single victim into the architect of humanity's near-extinction.

In Their Own Story

The rain slicked the pavement of the bustling city square, masking the cough that tore through the stranger's chest. He clutched his side, eyes widening as a feverish haze clouded his vision. A tourist bumped into him, laughing at his stumble, unaware that a microscopic war had just begun in their skin. Within an hour, the stranger was gone, dragged away by paramedics who would never make it back to the station. By morning, the square was empty, save for the moans of those waiting to rise.

Audio logs and environmental storytelling reveal that the collapse began not with a bang, but with a whisper of denial. Scientists initially struggled to classify the pathogen, mistaking its rapid mutation for a standard influenza variant. This delay allowed Patient Zero to infect critical infrastructure workers, spreading the virus through airports and hospitals before containment protocols could be activated. Society fractured as panic set in. Governments attempted to cordon off major cities, but the sheer speed of transmission rendered these efforts futile. The military was overwhelmed not by a foreign army, but by their own citizens turning on them within hours of exposure. Supply chains collapsed instantly, leaving millions trapped without food or medicine. The final nail in the coffin for organized society was the loss of communication networks. As power grids failed and radio towers fell silent, isolated pockets of survivors were left to fend for themselves against the rising tide. The Green Flu turned the world into a chaotic battleground where the only rule was survival.
