Mo Yu

She was originally an orphan who owed a debt to Elder Yu. When Gu Ruoyun first left the Gu Family and wanted to create a force she was one of the first members. When the Devil Sect was officially formed she became one of the Protectors (leader) and the Head of the Pill Hall.

She was beaten by a member of Dark Yin Palace while trying to protect Bai Chuan from being kidnapped to force Gu Ruoyun out of seclusion.
