While the court was still fighting for power and profit, his fiefdom had quietly evolved into an industrial beast. When the rogue bandits invaded the territory and the Tatars came to the pass, the heroes of all walks of life were shocked to discover that this vassal king had already built a war machine capable of crushing the old world!
