The Dragon King is the personal vessel of the Mercenary King Barbarossa Rugner. The entire ship is made of solid gold. The finest quality gold was shipped in from various mountains around the world to construct it. Originally, the ship was not meant to actually sail. Barbarossa had it built because he thought he had too much money, and wanted a conversation piece. However, an exceptional group of shipbuilders actually managed to make the ship float and so Barbarossa figured he would use it.
