The Fawn is a ship.
A Dance with Dragons
On the first day of their stay in Volantis, Prince Quentyn Martell, Ser Gerris Drinkwater, and Ser Archibald Yronwood seek passage on the Fawn to sail to Queen Daenerys Targaryen in Meereen. The captain of the Fawn is the only captain to give reasons for refusing them passage. Speaking with the three Dornishmen over watered wine, the captain explains he will be sailing on an already dangerous voyage past Valyria to New Ghis, Qarth, and the Jade Sea. It would be too much of a risk for him to take the Fawn to wartorn Slaver's Bay.
Every voyage has its perils, long ones more than most. Why should I seek out more danger by turning into Slaver's Bay? The Fawn is my livelihood. I will not risk her to take three mad Dornishmen into the middle of a war.—the captain of the Fawn to Gerris Drinkwater
