Talia was born in the spring of 108 AG on Kyoshi Island, her birthday falling a month after her mother's. At age six, she began her training towards becoming a Kyoshi Warrior, mostly working under her mother, who had assumed the leadership role seven years prior. She mostly trained in chi-blocking, but worked with other warriors in mastering fans, katanas, and other arts. In 120 AG, at age twelve, she was inducted into the Kyoshi Warriors.
At age fifteen, Talia met and befriended Kya, the then-twelve-year-old daughter of Katara and Aang. Their respective parents already being good friends, Talia and Kya quickly got along after they first met. They spent many days together while Kya's parents stayed on the island on vacation. However, they soon encountered the Xolan Bandits within the mountains. Using combined, effective strategy and solid teamwork, the two girls survived and allowed the opening that was used to capture the bandits. After this, Talia and Kya become close friends like their mothers, and remain this way today.
Another four years after this event, Ty Lee stepped down as leader of the Kyoshi Warriors, allowing the twenty-year-old Talia to take over the role. She assumed her role quickly and very seriously, making sure the warriors were up to snuff; though nevertheless, she would be encouraging and helpful, much like her mother was as leader. Talia proved to be the island's most effective leader; during her time, crime rates dropped 27% on the island, with the Kyoshi Warriors' average capture rate dropping from 5.3 days to 2.5 days.
In 152 AG, Mayor Oyaji II passed away at age 83, opening the mayor's position. Talia, now 44, was given the chance to lead the island in the light of her phenomenal leadership of the Kyoshi Warriors. Talia indeed announced that she would step down to become Kyoshi Island's mayor.
