The Glass Sphere — Pearth

The Glass Sphere

499 Million Souls,
One Fragile Shell

An engineered world orbiting 900 km above a dying Earth — held together by a fragment of dead star at its core.

Pearth — An Engineered World

Engineered to Endure

Built to Last Forever.
Quietly Coming Apart.

Beneath the electrochromic sky, a century of carefully maintained lies.

Existence — Hardcover Edition
The Book

A Century After
Earth's Fall

Humanity survives on Pearth — an exquisitely engineered planet built to endure, now quietly unravelling beneath the weight of buried secrets.

When the Council's grip on Pearth begins to crack, a chain of events is set in motion that no one saw coming — and that no one can stop.

Drawn in are Koa Kent — a retired pilot with a fractured past — and his brother Kahu, a gifted hacker caught in a battle he never chose. Together they unravel encrypted archives, haunted histories, and Existence — a hyper-immersive simulation of 1970s Earth where memory, identity, and reality begin to fracture.

"The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion."

Pearth — The Glass Sphere
The Setting

Pearth

An engineered world orbiting Earth at 900 km altitude, housing 499 million survivors. At its centre: The Heartbeat — a presolar stellar remnant from asteroid 2056-Varuna, older than the sun itself. Compressed within osmium, iridium, and platinum-group alloys across 47 nuclear detonation cycles over eight years, the resulting core generates exactly 9.81 m/s² of gravity, radiating outward to every surface above it. Earth-normal gravity — achieved through mass and physics that existed long before humanity did.

Four quad climates — Plasma, Solids, Liquids, Gases — each built terrestrially by a different nation over twenty years, then lifted into orbit via nuclear pulse propulsion and docked to the core. Triple-pane electrochromic glass seals the sky: blue by day, transparent at night — 499 million people looking up at the real stars, and below them, always, the pale glow of the world they left behind.
