What the Hell Happened to the World?

After the Great War, the surface was rendered uninhabitable. Humanity fled underground into the metro systems — a twisted network of half-collapsed stations, forgotten military installations, and repurposed ruins.

For decades, fragile alliances held society together. But now, everything has fractured. Civil war. Rogue experiments. Ancient technologies buried under rust and blood.

The Redline, once a beacon of order, became something darker—authoritarian, obsessed with control, and now rumored to be breeding horrors in places like Radon-8, their infamous prison-lab.

The Phoenix Guard, once Redline’s elite, broke away to preserve what was left of human dignity. But they’re scattered, hunted, and outgunned.

A cult that emerged from the Northern districts, the CRUX believes in prophecy, mutation, and salvation through suffering. They’re feared for their fanaticism and disturbing rituals. Few speak of them openly—and those who do, often vanish.

“Some say the CRUX found salvation… others say they just went mad.”

The network of exiled stations, silent and unacknowledged. The Redline refuses to speak of them—some say out of fear. They operate beyond the known metro grid, shrouded in secrecy. Their motives are unknown, their presence... unsettling.

“Even the Redline won’t go near them. That should tell you everything.”

Beneath all this lies something worse: the whispers. The things in the dark. The truth no one survives long enough to tell.

Some say It was born in Noremberg. Others say It is still watching.

This is not a story about saving the world.
This is about surviving what’s left of it.
