Captain Silver's Cave is a dungeon location in Romancing SaGa: Minstrel Song. Hidden amongst the jungle on Walon Isle, the cave is where the famous pirate Captain Silver hid their treasures; The most valuable of which is the Opal Fatestone. By talking to the chief of Geckling Village you can acquire a crude map of the jungle. The map points the way to Silver's Cave, as well as Twinmoon Temple. The cave system itself is full of traps and false walls, making it impossible to progress through the caverns without the appropriate proficiencies.
