Pirate Flags are found in the game when you reach the 4th Generic Puzzle, *The Monk's Stage is before this* and this is used as a lever rather than a Flag. One is simply found near Hermit, The Second is past the Hermit near a cave tour sign,And the Third is found underground. Besides using this to get into a passage order to beat the puzzle *along with getting a Cave Painting for the Adventurer* , the Flags don't have too much importance.
