The Empty Throne that Imu occupies in One Piece holds a significant symbolic value. It's officially stated to be unoccupied to maintain peace and equality among nations, symbolizing that no one person will take full control of the world. However, the throne is secretly occupied by the enigmatic sovereign Imu, whose authority supersedes that of the Five Elders. The 19 weapons in front of the throne represent the founders of the World Government, and all royals must pledge not to take the throne when they come to Levely. This throne is a symbol of peace, equality, and the shared power of the world's nations.
