The Expedition Ship

The enormous vessel — "a giant ship made for the queen" — carrying the reclamation
expedition from Port Quaybay to Rivalon in Orathos. Sails and an
engine; famously (and demonstrably) both fireproof and waterproof. Crossing time:
21 days nominal, 10–40 depending on winds. It runs the route every ~40 days.
