The Goddess is a ship.
A Dance with Dragons
During their stay in Volantis, Prince Quentyn Martell, Ser Gerris Drinkwater, and Ser Archibald Yronwood seek passage to Queen Daenerys Targaryen in Meereen. Returning from the Volantene docks, Gerris reminds Quentyn that the Goddess sails for New Ghis on the morrow which would bring them closer to Daenerys. Quentyn agrees that they would be closer to but they could find themselves stranded on the island as New Ghis has allied with Yunkai. The Goddess sets sail for New Ghis roughly around the time the Dornishmen join the Windblown mercenary company.
