Under the guise of a man, Sungnyang dedicated herself to liberating women destined for the Yuan court as concubines. King Wang Ko tasked her with a perilous mission: to gain the trust of Wang Yu and draw him into a planned ambush.

Sungnyang confided in the Crown Prince, revealing the presence of a spy within their ranks. As a consequence, Prince Togon was banished to Koryo.

Sungnyang, in her haste, took the Yuan Prince for one of his soldiers. Concerned for his safety, the Koryo King ordered the prince sheltered within the walls of the Koryo palace.

The Prince of Yuan requested that Sungnyang instruct him in the arts of self-defense. Meanwhile, El Temur plotted a comprehensive assault upon Daechong Island, intending to eliminate the prince.

Sungnyang and Prince Togon pressed onward toward Kaegyong, their destination the Koryo King. Simultaneously, El Temur seized control of the Koryo palace.

Yom, deceived by Sungnyang’s stratagem, orchestrated the introduction of Prince Togon’s body into the palace. The sight stirred a profound conflict within Togon; he wrestled with the choice between revealing the truth and ascending to the t…

The King of Koryo discovers Sungnyang’s true gender and resolves to shield her from the dangers posed by the Tangqishi. Elsewhere, in the Yuan capital, Tanasiri diligently prepares for her role as empress, undergoing rigorous instruction.

Beneath the veneer of celebration, Sungnyang weaves a plan for vengeance against Emperor Togon, her heart a cold forge of resentment. Meanwhile, a contest of arms is arranged: the King of Koryo and Yom Byongsu will clash in a duel for the c…

King Koryo’s victory over Yom brought him command, yet he was left with inadequate resources to prepare for the coming war. El Temur, upon learning that the Emperor had taken a concubine, flew into a rage.

The King of Koryo led his troops to a hard-won victory over the Turks, a first for his people. Following the battle, he took Sungnyang into his personal company.

The Empress commanded Sungnyang to administer a powder to Lady Pak, a substance intended to induce a miscarriage. Meanwhile, the Emperor’s suspicion of Nyang's true identity deepened.

Nyang received a direct order: to disseminate rumors questioning Lady Pak's pregnancy. Meanwhile, General Bayan, having taken the guise of Batolu, found himself embroiled in unforeseen difficulties upon reaching the battlefield.

Lady Pak was summoned before the inquisitors for further questioning. Sungnyang received a written assurance of her release from the palace, only to be intercepted by the Emperor himself.

Victory seems to follow Wang Yu as he enters the Yuan Palace. Whispers persist that the late Yuan Emperor penned a blood oath before his passing, and now a frantic search for it consumes everyone.

Wang Yu conceived a scheme to provoke El Temur, a plan requiring Sungnyang’s assistance. Meanwhile, the Emperor issued a challenge to Wang Yu: a game of soccer.

El Temur sought the originator of the plea, his efforts a persistent thread in a complex tapestry. Wang Yu discovered that Sungnyang had been the source of assistance, and with that knowledge, he resolved to avoid her future presence.

The Emperor and the Queen Dowager inquired of Wang Yu whether he harbored any interest in taking a princess as his wife. Meanwhile, the Emperor prepared a shadow play for Yang, though the performance was soon intruded upon by unexpected com…

A tide of rats invades the palace, heralding the resurgence of the late Khan's curse. Faced with this renewed threat, the emperor resolves to actively seek out the Blood Vow.

Wangyu and Yeonchul devised a plan to simulate Yeonchul’s demise, intending to discern his true loyalists. Meanwhile, Nyang conveyed to the emperor her desire for no further communication.

Wangyu sought out the Dowager and, through careful words and actions, managed to gain her confidence. Later, he turned to Nyang, inquiring whether she would consider becoming his Queen upon his return to Koryo.

The Regent granted Wang Yu leave to return to Koguryo, citing the illness of his father as the reason for his journey. Meanwhile, Nyang and two others remained behind, tasked with the search for Jukho and the blood vow.

The emperor ordered Nyang concealed within the pavilion, a precaution against the regent’s agents discovering her. As Nyang’s companions attempted to spirit her away, they fell victim to a band of thieves.

With the arrival of her son, Nyang bore a child distinguished by a singular mark upon each foot. News of this unusual birth reached the ears of the emperor and Wang Yu, who, consumed by resentment towards the empress, began to plot their re…

In the Liaoyang province, Bayan encounters Nyang during a slave sale. Nyang, in turn, uncovers a blood vow and reveals it to Bayan.

As Nyang navigates the trials the Empress designs, she commences the selection of suitable consorts. Meanwhile, Wang Yu persists in uncovering the source of the counterfeit currency.

Nyang assumes the position of consort and, with allies from Koryo, engages in conflict with the empress. Meanwhile, Wangyu strives to prevent the influx of counterfeit currency into Liaoyang.

Each evening, Nyang would instruct the Emperor in the arts of reading and writing, cloaking their lessons in the guise of festivity. But the Empress, perceiving this clandestine education, resolved to confine Nyang within the archives, assi…

Nyang initiated her scheme to wrest authority from the Empress. Meanwhile, Wangyu sought out Hukso, arranging for Musong’s return by informing Hukso that Musong was the husband of El Temur's niece.

News of Nyang’s plight reached Wang Yu through Tal Tal, following the capture of Huksu. Undeterred, Nyang pressed onward with her campaign of retribution against the Empress.

The parting between Nyang and Wangyu arrived, a quiet severing of paths. Meanwhile, Feisu, after considerable effort, brought the translation of the book recovered from Huksu’s dwelling to a close.

Before El Temur, the Emperor addressed him, demonstrating his literacy. Meanwhile, Tal Tal presented the spies of Eagle House to the assembled governors.

Nyang deflected El Temur's shot, skillfully shifting blame to another governor for the failed assassination attempt on the Prince. The Empress then summoned Wang Yu and Nyang to share a drink.

The coup failed, and Nyang and the Emperor lived to see the aftermath. Yet, the Emperor was wounded by a poisoned arrow. In the chaos of their escape from the pursuing guards, Wang Yu was struck by a blade while assisting Nyang's flight.

News of the Emperor’s affliction reached Nyang and her household, threatening them with repercussions. But the Emperor himself intervened, arriving to shield them from any blame. Yet, the Empress, consumed by a vengeful resolve, plotted a d…

Following Nyang's recovery of the talisman and the breaking of the curse, El Temur began to be plagued by nightmares. Meanwhile, Wangyu commenced training the vagrants that Wongjin had brought as new recruits.

Bayan commenced his campaign against El Temur, marching his forces toward the capital city. News reached El Temur from his scouts: Bayan was advancing, and victory seemed assured.

Within the Ice Palace, Nyang summoned all to begin preparations for the Emperor’s defense, as Bayan seized control of the fortress. Wangyu fulfilled his duty, opening the gates to allow Bayan’s soldiers passage within.

The Dowager vehemently opposed Nayng's ascension to the throne, compelling Bayan to exile his niece. The former empress met a public and brutal end, hanged in the square for all to witness.

With the ascension of Bayan Hudu to empress, Nyang persists in her quest for the hidden treasury. Meanwhile, Wang Yu joins the search, driven by a desire to secure the funds and ensure Nyang's successful coronation.

The truth of El Temur's hidden wealth reached Nyang's ears at last. Meanwhile, Bayan declared to the Emperor his ambition for war, outlining plans to conquer the neighboring lands.

Nyang and Wangyu initiated their scheme to extract the funds from El Temur’s residence. Tal Tal, discovering he had been deceived by Nyang and Wangyu, hurried back only to find the hidden chamber bare.

Wang Yu returned to Koryo and assumed command, a decision made by ceasing all provision for Yuan. Meanwhile, Bayan led his forces into war against the neighboring countries, seeking to conquer them.

The Dowager and Bayan accuse Wang Yu of supplying explosives to states hostile to Yuan. Stripped of his rank, Wang Yu is forcibly taken to Yuan by the prince and Tanguishi.

Kim Sunju arrived precisely when needed, averting the execution of Wang Yu and his retinue. The Emperor, having broken his word to Nyang, resumed his drinking.

The Empress learned of Maha’s hidden origins through a calculated threat leveled against Yon Hwa. Meanwhile, Nyang informed the Dowager and Maha that a full disclosure of long-held secrets was imminent.

Driven by the startling revelation that Maha is his son, Nyang races to ensure his safety. With the truth of Maha’s parentage exposed, he is cast out from the palace.

Wang Yu sought out Maha, resolving to take him to Koyro and reveal everything. Meanwhile, the Eagle House desired Yom Byung Soo to visit Bayan.

To prevent any knowledge of his awakening, Nyang confines the Emperor to his chamber. Meanwhile, Bayan is imprisoned for attempting to murder Nyang and her son, Ayu.

To atone for her transgressions and seek absolution, Nyang was dispatched to the temple. Meanwhile, Wang Yu directed the entirety of his purchased grain to the palace, for distribution amongst the populace.

With Nyang’s ascension, the Empress of Yuan was secured, and Wang Yu claimed his rightful throne. Now Empress, Nyang turned her attention to the Eagle House, determined to uncover their secrets and seize their holdings.

Despite knowing Kolta’s position as head of the Eagle House, the Emperor persists in drinking the poison Kolta provides. In a dramatic display witnessed by Nyang, the Dowager takes her own life with poison.
