The Ramparts Of Ryousan, also called the Dragon Ramparts, is the ancient capital of the Odaku Empire. It is located on the side of a mountain in a desert region, and situated not too far away from a river (This river was big enough to allow Norvagen Man O' Wars to sail down). It was also the site of the last great battle of the Metal Ages between the Odaku and the combined forces of the Norvagen, Draigar, Ferroch, and Fyren.
The Ramparts Of Ryousan is similar to the Great Wall Of China in design.
