The Ancient Castle is a ruined castle buried between Kohlingen and South Figaro in Final Fantasy VI. It is accessible once the Falcon has been obtained. While traveling beneath the sands, the man responsible for Figaro's dive engine will mention they stumbled upon something; the player should decline further movement and go to the prison cells where the cell on the far right will provide the entrance to the Cavern to the Ancient Castle. Many enemies in the area automatically have Reflect status and high Magic Defense.
