- First read: five headings, 774 words, the Turn 282, the Tale 155 - five over its window. Five dated events, three people one per guild, the Law one paragraph. No fact contradicted; "human-pulled sledges" and "never iron" appear twice each, fact 6 and fact 4 restated rather than used. The Law's breaker is Serek, the Mudwalker from "Three People", barred by "the three guilds". The Tale is told ("Come close, little ones, because this is a nine-day tale") and ends on an instruction. Three follow-up chips, one of them "Check the word count and constraints".

## Answer

The Turn

Dawn is only a pale seam above the wall when the warning clappers begin. I am already on the seaward stair with half the town, shoulder against shoulder, all of us looking over the parapet toward the flat. Yesterday it was mud from here to the mainland, a hard two-hour crossing marked by sledge tracks and footprints. Now water shines in the far channels.

It comes quietly at first. Thin streams find every hollow. They join, widen, and spread until the flat seems to loosen beneath them. Nothing moves out there. No Mudwalker, no loaded sledge, no traveler late for the gate. On the Turn, the flat belongs to the sea.

Below us the Gatewrights watch their bronze and wooden fittings. The sea gate is shut. Water reaches the wall, rises against it, and the Reach becomes what it was not yesterday: a town cut away from dry land.

Then the fishing begins from within the safety of the walls and gate. The Turn must feed us through eight dry days, so there is no idleness. Fish come in wet and flashing, passed hand to hand toward the Saltbinders. Their work will continue long after mine is done, curing and storing what today provides.

By full morning, I cannot see a footprint anywhere. The road across the mud is gone as completely as if nobody ever walked it.

Everyone knows that by tomorrow the water will withdraw and the Mudwalkers will test the flat again. People will bend under packs. People will lean into sledge ropes. The long crossing will return.

But today there is only water, wall, and waiting, and the knowledge that nine days have closed their circle once more.

Three People

Serek is a Mudwalker who reads the drying flat before leading people with packs and human-pulled sledges across it. He carries wood and bone gear, never iron, because anything taken onto the flat must survive the next Turn.

Mora is a Saltbinder who measures her work by the eight dry days that every catch must outlast. On the Turn she receives fish as quickly as they can be brought in and begins curing and storing them for the town.

Vesk is a Gatewright who tends the sea gate and its bronze, bone, and wooden parts. At dawn on the Turn, his whole trade has one purpose: the town must be closed before the returning sea covers the flat.

Timeline

Year 1: The Reach is founded behind its wall on the tidal flat, dependent on the nine-day rhythm of sea and mud.

Year 18: Regular crossings make the Mudwalkers necessary guides for travelers, loads, and human-pulled sledges during the eight dry days.

Year 47: The Saltbinders establish stores sufficient to preserve the Turn's fish through the eight days when the sea is gone.

Year 93: Gatewright practice settles around bronze, bone, and wood after generations confirm that iron exposed on the flat cannot survive a Turn.

Year 212: The Reach numbers 4,100 people, governed by its three guilds and still keeping its single law.

A Tale They Tell

Come close, little ones, because this is a nine-day tale, and those should never be told from across a room. Once there was a child who asked the flat, "Why must I stay behind the wall when the sea returns?" The flat was dry and gave no answer. So the child waited.

At dawn on the ninth day, water slipped into every crack and hollow. Soon there was no path, no footprint, no place where a careful foot might bargain with the sea. The child watched from the wall until water covered everything between the Reach and the distant dry ground.

Then the child understood. On eight days, people may cross the flat, and Mudwalkers may show them where to go. On one day, nobody is wiser than the water.

So remember what the child learned: when the Turn comes, watch it. Hear it. Thank it for the fish. But watch from inside the Reach.

The Law

The Reach has one law: nobody may be on the flat on the day of the Turn. Its simplicity leaves no guild above it and no reason for travelers, workers, or guides to misunderstand it. Serek was the last to break it. He stepped onto the flat after dawn on a Turn, when the returning water had already begun spreading through the mud, and people on the wall saw him there. He came back inside before the flat was covered, but returning safely did not undo the breach: the three guilds barred him from guiding crossings, because a Mudwalker who enters the flat on the forbidden day cannot be entrusted to lead others across it.
