Upon arriving at the Northern Water Tribe, Sokka was smitten with Yue, taken by her beauty at first sight. He carved a betrothal necklace for her to mark their engagement, but she did not really love him and consented to the marriage only to stay in line with her people's customs. Sometime prior to Team Avatar's arrival at the Northern Water Tribe, it was arranged that Yue would marry a young, egotistical warrior named Hahn.
Thus, her parents named her Yue, for the moon. The Moon Spirit gifted her with part of its own life force, saving her life and turning her hair white as a side effect. As her condition was critical and the tribe's healers, including Yagoda, could not cure her, Arnook prayed to the Moon Spirit in desperation and placed her in the tribe's Spirit Oasis.
She had an unknown illness as an infant, being still and quiet as though asleep, so her parents feared she would die.
Yue was born in the Northern Water Tribe's capital of Agna Qel'a to Chief Arnook and his wife, the daughter of a tribal chieftain.
