To fight the Rouran raiders, the Khan of the Wei dynasty begins a campaign against their khaganate bringing together soldiers old and new from the battalion captain Mulan Hu to the General Tuyuhun. Yet, alas, the General is wounded, his eldest son dead and his daughters out avenging their brother's death, leaving the youngest of his progeny, Chuo, to rise to the occasion and prove himself the equal of his siblings.
"Tuyuhun: A Tale of Mulan" is based on historical fact and the original ballad, told from the perspective of a different soldier in Tuoba Buri's campaign against the Rouran. This was not a time where Han Chinese fought foreign invaders, this was a time where Proto-Mongol state fought Proto-Mongol state and man and woman alike could fight in the service of their Khan, as long as they were Xianbei.
