Stratos

Stratos is one island, volcanic, mostly rock, off the northeast coast where the maps go vague. Twenty thousand people live there and most of them are related. They fish, they cut turf, they argue about grazing rights, and they keep records the way other nations keep armies.

For nine hundred years Stratos has logged the sky currents that pass over the island, every shift and every season, in a hall that has never burned. Britannia's airships ride those currents. Britannia's own charts go back sixty years. The rest of the pattern is in Stratos, and Stratos has never sold it.

The island stays out of every war by being too far and too poor to bother with. That has worked for centuries. Then last spring a Britannian ship anchored in the harbor for a week, left with a sealed crate, and the keeper of the record hall was found in his boat two days later with the tide.

The council has not said what was in the crate. The younger islanders have started counting who bought a new roof this year.
