A Korea-born warrior girl had to be a servant at the Mongol Yuan court but somehow overcame her low status to become an empress in another land.

Sung Nyang was born a girl but now pretends to be a boy to avoid becoming a palace maidservant. To get revenge on her enemies, she hides her true identity but gets caught up in a Yuan Dynasty conspiracy while watching over the Yuan crown prince To Gon, who was exiled to Koryo. Through a series of twists and turns, she saves To Gon, but her secret about being a woman is discovered, and she is forced to become a royal maidservant. To Gon was the rightful heir to the throne, which was stolen from him by his half-brother, who then exiled him to Koryo. To avoid being murdered, he plays dumb, but he has a fierce rage and sadness within him. He eventually returns to Yuan and becomes Emperor, and with the help of Sung Nyang, a royal maidservant, he becomes a dignified king and fights against those who are a threat to him.—Rakuten Viki

Genghis Khan built an empire that spanned vast regions in East Asia and East Europe. And there was one woman who held immense power in the Yuan Dynasty, which Genghis Khan founded, for 37 years. She was neither of Mongol descent nor from the Han Chinese. She came from Goryeo, a small kingdom in the Far East. She was taken to Mongol against her will as a Gungnyeo (palace women) but somehow overcame her lowly status to become the last empress in another land. Her name was Empress Ki.—MBC
