Jinora, the eldest daughter of Tenzin, showed an early interest in books and was generally quiet, which allowed her to focus on her airbending training. She was naturally gifted and had a unique affinity with spirits, which was a rare ability among humans. This connection to the spiritual world played a significant role in her mastery of airbending. As a result, she became the youngest known airbending master, surpassing even Avatar Aang's record. She was also the first of her generation to achieve this status.
