King Caspian's ship in The Voyage of the "Dawn Treader", one of C.S. Lewis' Chronicles of Narnia. Seafaring had all but died out prior to Caspian's reign; the previous Telmarine rulers of Narnia were fearful of the sea. Caspian reawakened the art, however, and the Dawn Treader was the greatest ship of its time.
Caspian, Reepicheep, Edmund and Lucy Pevensie, and Eustace Scrubb sailed in the Dawn Treader to the World's End on a quest for the seven lords whom his uncle King Miraz the Usurper had put to sea to get them out of the way.
