Hei-Won first met Avatar Aang while she was walking through the streets with one of her fellow members of the Official Avatar Aang Fan Club, introducing herself as one of its co-founders. She subsequently escorted the Avatar and Katara to their clubhouse, which was supposedly modeled after the Western Air Temple. Later on, she introduced him to another club member, Yee-Li, who showed him an airbender flute she had bought from a traveling merchant. Later that year, she became one of the first Air Acolytes, along with the rest of the club.
