浮世 The Raft World

The hinge

The first farmers were reef-farmers: domestication began with kelp, shellfish and the lash-palm whose buoyant timber grows in salt lagoons — and every subsequent civilization compounded seaward. Ten millennia of maritime ingenuity; none of terrestrial.

What it cannot do

• Land is not forbidden, merely wild: the interiors hold forests, beasts and the Landed — small hard peoples who walked inland long ago — and every raft-nation's maps go white a day's march from salt water.
• Everything civilized floats or clings: raft-cities, stilt-coasts, reef-farms. Deep-land resources — ores, timber beyond the shore belts — come from expeditions that are half mining, half legend-making.
• The sea's rules still rule: storms cull, currents dictate the political map, and no city is ever finished — a raft-nation is rebuilt continuously or it is driftwood.
• Metallurgy came late and lean (fire and forge sit badly on decks): the world is a genius of rope, timber, shell and salt-chemistry, and iron is precious the way silk is elsewhere.

Geography

The world's nations are current-nations: great raft-cities riding the gyres on ancestral circuits, stilt-woven coastal leagues, and the reef-farm shallows between. The continents loom over it all — green walls at the edge of civilization, sources of timber, ore, and stories to frighten children.

The Gyre Capital, Moana-Roa. The greatest raft-city: a lashed continent of ten thousand hulls riding the long circuit, rebuilt plank by plank forever — its oldest timber is younger than its youngest law.

The Stilt Coasts. The woven shore-leagues: cities on legs in the tidal belts, half in the sea's economy and half brokering the land expeditions — the raft-nations' merchants and the Landed's only regular guests.

The Green Interior. The continental wilds: hardwood cathedrals, ore mountains, the Landed's territories — entered by licensed expedition, mapped in rumor, and mourned in every ballad about the crews that stayed.

The look

Rope-and-timber civilization at oceanic scale: sail-forests over lashed platform cities, kelp-farm grids to the horizon, shell-inlaid longhouses on stilts — and behind every coastal scene, the dark green wall of the untouched land.

Peoples

Gyrefolk. The raft-nations of the open circuits: fisher-farmers, riggers, current-priests — whole cultures that have not touched land in generations. They prize buoyancy, repair, the circuit kept. Gyrefolk bury nothing: the dead are given to the current at the circuit-point where they were born, and a nation's route is therefore also its ancestral map — 'we sail through our grandmothers' is meant as comfort, and is.

Coastweavers. The stilt-leagues: brokers, boatwrights, expedition outfitters — the amphibious middle of the world. They prize the tide-table, the brokered peace, craft above cargo. A coastweaver house is rebuilt one leg per year by obligation, neighbors' hands, feast supplied — the rolling renewal that means no stilt-city has ever been old and none has ever fallen.

The Landed. The interior peoples who walked away from the sea in the deep past: forest nations, ore-hill clans — few, tough, and owed ten millennia of maritime condescension they do not accept. They prize ground, patience, the long watch of the coasts. The Landed trade with expeditions at fixed forest-edge grounds and never aboard anything that floats — their one universal law, whose origin story every clan tells differently and all tell darkly.

Law

No admiralty rules the world; the currents do, and the nations riding them negotiate at the circuit-crossings. The nearest thing to world law is the Lashings — the code of mutual rescue, salvage and harbor that every hull learns before it learns anything else.

• The First Lashing (Rescue Absolute) — The sea outnumbers everyone. Any hull answers any distress, enmity suspended — the code older than any nation, and the reason wars here have intermissions.
• The Timber Tithe — Raft-cities eat wood forever, and the lash-palm lagoons were once stripped to war over. Every nation now farms replacement timber at treaty lagoons — the tithe registers are the world's real armories.
• The Expedition Charter — Freelance land-crews used to vanish, or worse, return followed. Interior expeditions now require charter, Landed ground-right fees, and the sealed manifest — because what comes out of the green is everyone's problem on a raft.
• The Ballast Court — On a floating nation, hoarding weight is hoarding everyone's freeboard. The great raft-cities' oldest tribunal audits mass, not money — and 'called to ballast' remains the phrase for any reckoning with what you've been carrying.

Economy

Currency: Shell-scrip locally; iron by weight for anything serious — the metal money that can't rust away being, on the sea, the point of the joke and the price of everything.

Reef-agriculture feeds the world, the timber lagoons rebuild it, and the interior expeditions spike it with ore and hardwood; the coastweaver leagues broker all three, and the gyre circuits are the trade routes, calendars and nations at once.

A day in the life

Morning. The city wakes by watches, not hours: nets up, decks sluiced, the repair rosters called — every citizen owns a maintenance verb before breakfast.

Food. Kelp, shellfish, reef-grain and the thousand ferments of a civilization that salts everything; an inland expedition's returned fruit is a festival and a health hazard.

Work. Farm the reef, rig the sails, weave the stilts, keep the circuit: the sea is the economy, and the green wall is the economy's dare.

Night. Current-priests read the water at the steering rails; the lantern-lanes of the raft-city sway together, and the ballads are all the same two subjects — the storm survived, and the crew that went inland.

Live tensions

• The interior expeditions keep growing — iron hunger is structural — and the Landed's forest-edge patience is measurably shortening: the fixed trading grounds have moved seaward twice in a generation, which everyone understands and no one says aloud.
• Moana-Roa's circuit is warming off its ancient track, and a capital that IS its route faces the unaskable: change the circuit and stop sailing through the grandmothers, or keep faith with a current that is leaving.
• Deep-kelp blight is moving along the gyres with the trade, and quarantining a current is a thing the Lashings never imagined having to lash.

Story seeds

• A chartered expedition returns on schedule with its manifest sealed, its cargo perfect, and one crew member extra — counted by everyone, remembered by no one.
• A Ballast Court audit of the gyre capital finds a district running impossibly light, and the young auditor's night dive under the hulls finds the missing weight: cut lashings, and a city quietly being stolen from below.
• A Landed emissary breaks the universal law and boards a raft-nation — alone, unarmed, carrying an iron ingot as a gift and a warning in a forest tongue: something in the deep interior is moving toward the coasts, and the sea people should be told.

Glossary

• The Lashings — The universal sea-code: rescue, salvage, harbor — learned before anything, honored above everything.
• Gyre circuit — A raft-nation's ancestral route: its territory, calendar and cemetery in one moving line.
• The green wall — The continental interiors — civilization's wilderness, iron's home, the ballads' dark half.
• The Landed — The peoples who walked inland at the dawn — few, unbowed, and watching the coasts.
• Called to ballast — Audited for the weight you add to what everyone floats — the raft world's word for reckoning.
