The Masked Person

The masked person, or Li Yanru (李颜如, Lǐ Yánrú), is the eldest princess from the previous dynasty.

Appearance
Due to the severity of the burn on her face, Li Yanru is always seen with a black mask, although sometimes the burn scar before her left ear is still visible.

Relationships
She took charge of Qi Yan and Ding You's education in the unnamed valley.

She performed top surgery on Qiyan Agula with heartbreak grass, and gave her pills to end her menstrual cycle.

She once treated Wan Ningxiang's smallpox, bringing her back to full health, earning her the gratitude of Viceroy Wan and the devotion of Wan Ningxiang herself. She was also once in a relationship with Nangong Sunu, much to the ire and jealousy of Wan Ningxiang.

As the former Emperor's older sister, she was a trusted counselor in the court of the previous reign.
