Genghis Khan is the leader of a nation united from the tribes. He was victorious in the long war against the Chin, the Mongolians' ancient foe. Now trouble arises from another direction. His embassies to the west are rebuffed, his ambassadors are murdered. The nation must embark on their greatest journey where they face enemies: ancient, powerful enemies. But the khan has chosen a path that will lead to victory or utter destruction.
