The Sea Dragon is the vessel used by Justin and Feena in crossing the Sea of Mermaids when going to East Elencia. The vessel belongs to Gadwin, but it was later given to them as a token for their journey.
The Sea Dragon looks much like a fish outside, yet it was spacious enough to accomodate three to four passengers. It is a special ship built for sailing across continents, and it follows the waves and the winds by itself, thus its passengers can leave most of the journey to the ship itself. The sail of the Sea Dragon bears inscriptions of Dight Culture and the whole ship is very similar in appearance to Gadwin's home.
