The Causeway Rest

A Slack-Tide pilot's shack and fire on the last island before the south shore — the save-your-skin waypoint where the Sunken Stair Road makes its final crossing.

A single wattle-and-rope shack with a fire pit kept burning by whoever needs the crossing to know the timing. Doreth Sumb sometimes winters here when the tides are wild. It is not a settlement; it is a message: wait here, don't attempt the last crossing without a guide, and there are fish in the pot if you can wait till morning.
