Lake Rats

The Lake Rats live in the marshes on the shores of the great northern lake, in shacks made out of the timbers of ruined ships. They live by “wrecking“ - ie, luring ships onto shoals with false lighthouses and beacons. Because they're scorned by the rest of Calradia - ”all criminals, smell like marsh gas and mud and rotten fish” - they scorn everyone else back. Although mostly Sturgian, their ranks have been swelled by fugitives, debtors, and anyone else who'd rather live by a thieves' code than by the laws of nobles.
