Returned vessel threat
Returned vessels from the belly of the Maw.
The Ivory Fleet is Bonewake's returned armada: swallowed ships resurfacing from fog with bone-white rigging, pale sails, ivory accents, and no visible crew until too late.

The Clickbound Crews
The captains and sailors aboard are brine-bound, half-remembered, and under the Click. Their ships do not sail by wind. They sail by command.
When the Ivory Fleet appears, someone has already been swallowed from history.
