The Maritime Defense Force is a group from The Legend of Zelda: Phantom Hourglass. A group dedicated to protecting the seas in the World of the Ocean King, Nyave is the only known member of the force, but it is clear through in-game dialogue that he is not the only member. According to Nyave, a common food ration to members is Wood Hearts. Interestingly, Wood Hearts also appear as a treasure in The Legend of Zelda: Spirit Tracks, indicating that their value greatly appreciates over time.
