The World of Flotillas Adrift

The old world did not end in fire. It ended in water. This is what came after.

The Drowning

Three generations ago the last ice let go. The seas climbed — not in a season, but in a lifetime — over the river deltas, over the coastal cities, over the launch pads and the server farms and the borders of every nation that had ever been drawn. The towers went under with the satellites still talking to them. By the time the water found its new line, the maps were blank and the radio was only static and salt.

What floated, lived. Everything else is the Drowned World — a sunken museum of the age before, picked over by anyone with a hull and the nerve to dive.

The Drift Age

The survivors did not rebuild on land; there was none left worth the name. They built outward — lashing salvaged hulls, decommissioned rigs, shipping decks, and scavenged plating into floating platforms, and platforms into towns, and towns into cities that ride the sea itself.

A city on the water is a flotilla. It has no coast to defend and no ground to plant; it carries its fields, its cisterns, and its people on octagonal decks joined by walkways, glowing teal at the waterline so the night fleet can find home. A flotilla that stops working starves in a week. So nobody stops working.

This is the Drift Age. You were born into it.

The Currents — the ocean's political weather

The open water is not trackless. Six great ocean currents carve the world, and a flotilla rides one the way an old nation kept a border — by it you are known, allied, and judged. The currents are blocs as much as waters: the Teal Current (traders and builders — your home water), the Amber Current (old-salvage families, wealth and patience), the Crimson Current (the war-pacts, who negotiate once, if at all), the Olive Current (kelp-growers and quiet collectives), the Indigo Current (deep-divers and keepers of drowned-world tech), and the Green Current (the freshwater faithful and the newly risen). Share a current and trade comes easy and morale runs high. Cross one and the war-band opens.

The waters of the ocean

Above the political currents, the sea itself moves through a slower cycle — eight named waters that every flotilla drifts through together, in the same order, tide after tide. Each has its own temperament, its own gifts, and its own dangers:

The gyre always pulls a flotilla back to the Rustgyre eventually, and the cycle begins again — but a bold captain can pay a toll and turn the rudder early, riding out one water on their own terms before the tide claims them back.

The Leviathan

Not everything down there is wreckage. Something enormous still moves through the deep water, and once in a while it surfaces close enough to a flotilla to matter — a shadow under the hull, a wake that shouldn't be possible, and then it's there. Rulers who've met it don't agree on what it is, only that it takes a toll on whatever it passes and that it can be bought off, driven back, or — if a captain is bold and well-armed enough — hunted. The ones who've hunted it and lived keep the trophy where every visitor to their deck can see it.

Ghosts of the Old World

The wreck below is full of the age that drowned — and not all of it is rust. Drifting wonders are salvage too good to last: a Mars Relay Buoy still warm with an orbital signal nobody can answer, a Moonpool Observatory that charts stars for a world that can't reach them. They work for a while, then the current carries them off or the salt eats them through.

The great megastructures are the opposite — proof a flotilla has stopped merely surviving and started to mean something. A Beacon Eternal seen for a hundred miles. A Deepwater Reactor humming with borrowed power. The Convergence Engine — the crown of a true megaflotilla, ringed in arcing teal light, that says to every current at once: we are not adrift anymore.

The salvage economy

A flotilla lives or dies by what it can pull from the sea or the wreck below: kelp and fish for a fed and happy people, freshwater and coral for growth, solar and fuel for power and flight, scrap to build cheaply, and salt — still the old currency of the water. Every soul aboard eats and drinks once a tide. The tide turns on a fixed hour and the whole world turns with it: the levy comes in, the bills come due, the sick are counted, and the population shifts. Miss too many tides unfed and the decks empty out. The tide does not wait, and it does not forgive.

Faith and the gun

Land religions drowned with the land. New ones rose from the deck: Tidewright holds the tide itself as a law and a craft — live by its hour and it provides. Saltborn preaches that the sea unmade the old world to make a truer one — salt is scripture. Deepwake believes something woke in the deep when the cities sank, and the divers have seen its lights. Many flotillas keep no faith at all — Secular decks trust the ledger and the gun instead.

A flotilla is only as steady as its hand on the wheel: Federalist councils for slow, sure growth; an elected Republic for trade; a shared Collective for cohesion; a Salvage Junta when the guns must come first; or a Free Port, where anything sells and order is somebody else's problem. When parley fails, war on the water is total and close — flotillas cannot run far, so they raid decks, sink fleets, and strafe the platforms. Most rulers keep a warhead in reserve. Just in case the other one does.

Salvage a city from the drowned world. Build it on the waves. Outlast the drift.

You

You command a flotilla of the Teal Current — a few lashed platforms and a hundred souls when you cut loose, a megaflotilla and a name the other currents fear if you're good and lucky and ruthless in the right order. The other flotillas out there are real holdfasts with real rulers — Pale Tide, Saltsong, Stormwall, the Maelstrom Imperium, and the rest — each riding its current, each one tide away from feeding its people or going under.
