However, it sunk into the ocean after Bill created a large downpour of molten ore that destroyed most of the island. It was formerly occupied by the Silver Pirate Alliance and is the main setting of the Silver Mine Arc.
Silver Mine is a rocky island with its most recognizable feature being a silver fort located in the center of it. Within it Bill built his throne room where he meets with his subordinates, and sends the less able ones to work in the mines at the lower levels.
