This ancient castle floats in the middle of Lake Toran. It was formerly the headquarters of the Scarlet Moon Imperial Navy, but the castle was abandoned with the construction of the Floating Fortress of Shasarazade.
Since then, the lake castle had been occupied several times by different pirate and bandits groups but were repelled by the Imperial Navy each time. Eventually, the Zombie Dragon was placed here in order to ensure its abandonment.
