The Great Queen Seondeok

Court Lady Mishil seduces the kings of Shilla to gain enormous power and influence over the royal court, but a prophecy regarding twins promises her eventual downfall.

King Jinpyeong and Lady Maya have twin daughters, forcing the king to send the younger daughter away with the maid Sohwa before Mishil can get her hands on the girl.

Fifteen years later, Deokman lives a life of a merchant with her mother Sohwa. King Jinpyeong's line of male heirs comes to an end.

Deokman displays her wits against a Chinese official. Lady Mishil's personal guard Chilsuk finally tracks down Deokman as the twin, and attempts to kill her and Sohwa.

After her husband's death, Princess Chunmyung leaves for the countryside to give birth to her son and keep him far from the reaches of Mishil.

Chunmyung encounters Deokman and mistakes her for a boy. Deokman believes Chunmyung is a nun and saves her life.

Saved by Princess Cheonmyeong, Deokman feels somewhat intimate with her. Yusin saves Princess Cheonmyeong.

Deokman is arrested and brought to the palace, but Chunmyung intervenes and assigns her to be part of the Hwarang.

Yusin and The Followers of Maitreya return from the battle, only to face disdain from The Ten Elite Hwarang.

Yusin is being called to be under the command of Seolwon while Deokman stays in Amagseong Fortress.
