The Thousand-Year Rain

A hard-SF prequel to Waterworld Year 0 — Year 1200

The Thousand-
Year Rain

One family, forty-eight generations, from the depot operator who could have stopped the rain to the girl set adrift with the map on her back.

A novella in progress

Illustration: a clear night over open water. A thin line of stalled cargo arcs across the sky, and one bright point on it, the depot, stays fixed.

Why this exists

I did some nerding out on this once when I considered writing a Waterworld prequel fanfic for fun. Yes, I know how that sounds. This is the best I could come up with without turning Earth into a sterilized steam ball.

Read the premiseThe short version, and the physics

Nothing in the system ever malfunctioned.

Every component did exactly what it was designed to do.

A pre-deluge civilization mined and moved material across the solar system — asteroids, moons, dwarf planets — mostly by automation, because you cannot staff an operation spread across that many bodies. Earth was not the customer. Earth was the depot: inbound ice and ore arrived, were caught, braked, processed and purified, then shipped back out.

A plague collapsed the civilization. The mines kept running and the freight kept arriving, but the shipping network died and nobody was left to tell the depot to stop accepting deliveries. Processed water piled up in orbit. The depot could keep stacking it there until the stockpile became dangerous, or it could get rid of it safely. It did the safe thing: its emergency overflow procedure vents processed water, already slowed, into the atmosphere below.

The overflow was a temporary measure, meant to run until a human supervisor fixed the problem. There were no supervisors left. It was a safe, tested, boring procedure, and nobody had ever left it running for a thousand years.

A thousand years in one scroll

The Rise

A section from the Bay of Bengal to the Tibetan Plateau, through Everest. Scroll, and the years go by at a steady pace. The water does not.

Cross-section from the Bay of Bengal to the Tibetan Plateau with the sea at 8,150 meters. Only the top of Everest stands above the water.
