They were a band of elite warriors acting together under a common cause. Those historic warriors gathered by the great tactician Tubal-Cain were a flawless, unstoppable force, and they had yet to meet with even a single defeat on the battlefield. But their country's king was foolish. Frightened by the army's strength, he exiled Tubal-Cain and his men from the kingdom, and so they had lost their purpose and reason to fight.
