The Rusted Steel Knight was said to be a very important part and legendary figure of the Seven Stars War. Two years after the first conflicts erupted, it is said that a mysterious knight wearing a rusted armor appeared on the battlefields. Displaying excepcional strength and skill, he fought alongside the Duchy's forces against the Mardon Empire. Although his identity was lost in time, his feats remain remembered by some veterans and war entusiasts to this day. The rusty armor, heavily mocked even by his comrades in the past, is now object of praise and pride, being considered even a relic. The legend of the Rusted Steel Knight is said to have come to an end when, four months after his appearance, he misteriously vanished from the battlefields. His whereabouts, as well as that of his armor, are unknown to this day.
