// HISTORICAL RECORD

VARSOVIA TIMELINE

160 years of progress. They called it evolution. From below, it looks like burial.

2031

THE FLOOD

Climate collapse hits Central Europe. Mass migration south-to-north. Warsaw's population triples in a decade. The old infrastructure breaks.

2064

THE FRACTURE

The EU dissolves. Poland becomes a corporate-state. Axiom Corp buys Warsaw's governance contract. They rename it Varsovia. Nobody voted.

2089

THE VERTICAL BOOM

Axiom builds upward. Megastructures swallow the skyline. Old Warsaw is buried under layers of steel and concrete. The sky disappears for millions.

2123

THE COLLAPSE

Axiom's economy crashes. The lower levels are sealed and abandoned. Millions are trapped below. Corporate security pulls out overnight.

2189

NOW

The city has stabilised into four layers. The corpos rule from the Spire. Everyone else fights for what's left. Something stirs in the deep.

THE SPIRE

2189

Glass towers connected by skywalks. Private security drones patrol filtered air. The silence is expensive.

"The air smells like nothing."

NOT YOUR AVERAGE RPG

AI NARRATIVE

Every session is unique

No scripted dialogue trees. An AI narrator crafts every encounter, conversation, and consequence in real time. Your story has never been told before.

PERMADEATH

Death is permanent

No save scumming. No quickloads. When your character dies, they're gone. Roll a new origin, start again. The city doesn't care.

BODY SYSTEM

Every wound matters

Individual body part tracking. A damaged leg slows you down. A busted eye ruins your aim. Augment what's broken — but lose a piece of yourself.

DEEP LORE

Layers of mystery

Factions with agendas. Districts with history. And below it all, the Substrate — ancient, shifting, unknowable. How deep are you willing to go?

BROWSER-NATIVE

No downloads required

Play instantly on any device. Desktop, tablet, phone. Pick up where you left off. The Warrens are always waiting.

SESSION-BASED

Built for real life

20-40 minute sessions. Jump in, make choices, survive (or don't). Perfect for a commute, a lunch break, or 3am when you can't sleep.
