Shaman

The shaman was a firebender who worked with the Fire Sages. She was a spiritual expert, and she used her firebending to help heal others.

History
The shaman was in her temple, when she was approached by Fire Sages who found Korra. She dipped the Avatar into healing water, while Korra meditated on who she was, and had flashbacks of Wan's lifetime. When Korra emerged, the Shaman told her about the herd of bison she had been keeping since the Hundred Year War and told Korra that the Harmonic Convergence was coming, and Korra left to go and shut down the portals at the North and South poles.
