After losing her mother, Sitara was sold to Fatima's house, where she lived a happy life as a slave, learning scholarship and helping with housework. However, eight years later, when Tus fell to the Mongol invasion, she lost Lady Fatima and her fellow slaves and was taken as a Mongol prisoner. In her despair, she finds a goal: to reclaim the book 'Elements' taken by Tolui. Later, to work under royalty, she hides her identity and calls herself 'Fatima,' the daughter of a scholar. By Tolui's order, she serves his wife Sorghaghtani Beki, but she becomes enraged by her attitude and resolves to take revenge on the Mongols. After Genghis Khan's death, while acting as a spy under Sorghaghtani's orders, she is taken to Töregene because of a Jada stone. There, Fatima learns of the circumstances of Töregene, who also lost loved ones to the Mongols, and becomes her maid to plan revenge against the Mongols together.

Gender: Female Age: Mid-20s Background: Originally from the Merkit tribe, she became the sixth consort (wife) of Ögedei, the second son of Genghis Khan, after her tribe was destroyed by the Mongols. Like Sitara, she has a painful past where her home and life were completely stolen by the Mongol Empire. Characteristics: She is extremely intelligent, ambitious, and possesses insight that pierces through others. She immediately recognizes the talent of Sitara, who harbors a deep grudge against the Mongols and uses wisdom as a weapon, and makes her a close confidante to bring down the Mongols. She is a doting mother to her son.

The youngest son of Genghis Khan and the fourth prince of the Mongol imperial family, he is the one who led the Mongol army to invade Tus, where Sitara lived. He is the most bellicose of the brothers, making remarks such as wondering if they shouldn't just crush everything through war instead of bothering with diplomacy. He searches for scholars in occupied cities because his wife, Sorghaghtani Beki, wants the book 'Elements.' Among his Mongol allies, he is highly respected for making the empire strong with his excellent military talent, and he fully supports his brother Ögedei, who ascended to the position of Great Khan after their father Genghis Khan's death, showing great brotherly affection.

A male from Samarkand who was brought here by the Mongol Empire's invasion, just like Sitara. However, unlike Sitara, he wants to survive and succeed in the Mongol Empire by any means, believing that if one has ability, an opportunity for advancement has come. He was almost made a conscript to serve as arrow fodder, but by quickly learning the language, he volunteered as an interpreter and became Tolui's Persian translator. Since then, he has been living by working quite hard.

The primary consort of Tolui. She is from the Kereit tribe and is a Christian. She and Tolui have a very special and loving relationship. By asking Tolui to bring back 'Elements' when he acquired spoils during his expeditions, she unintentionally contributed to Sitara's tragedy, as Tolui captured Tus to fulfill this request. Aware of her position, she seeks to learn various knowledge, including 'Elements,' for the future of the Mongols. Coincidentally, this appearance is similar to Fatima's, causing Sitara to feel resentment and a desire for revenge toward her. Later, after Ögedei Khan's accession, she struggles to protect her husband and children, who have become targets of caution, even sending Sitara as a spy to Ögedei's side. Her personality seems gentle and thoughtful, but she is not easily defeated.

The primary consort of Ögedei. In the story, she was originally the wife of Ögedei's father, Genghis Khan, making her Ögedei's stepmother, but she remarried Ögedei following the custom of levirate marriage after Genghis Khan died. Despite her frail appearance, she has a highly political personality, to the point where Sitara shuddered, calling her a real witch. She originally wondered why he made her the primary consort when she was his stepmother and older, offering no political advantage, but she is sincerely loyal to Ögedei, who respects her character and abilities, and seeks the prosperity of the House of Ögedei itself for his sake.

The third son of Genghis Khan and the third prince of the Mongol imperial family. Unless there is an extreme exception, he is always smiling, and unlike his brothers who display the bellicosity typical of nomadic peoples to a cruel degree, he is a man of gentle character. After the death of his father Genghis Khan, he succeeds him as Great Khan and further expands the Mongol Empire. He took Töregene, who was the wife of Dayir Usun, the leader of the Merkit tribe whom he personally suppressed and killed after they rebelled, as his sixth consort. Even though Töregene openly shows hatred toward him because of the incident with Dayir Usun, he does not punish her and shows that he cherishes her in his own way. His eldest son, Güyük, is also Töregene's child. His personality is thoughtful and quiet, he smiles warmly, and he is very considerate toward his empresses.

The fourth consort of Ögedei
