Mother of Faces

The Mother of Faces is a spirit who lives in Forgetful Valley. She has the ability to give faces to living organisms, and as such many creatures in the valley have extra faces on their exteriors. She also owns a wolf, who like the many other creatures in Forgetful Valley has a face on its fur.

History
Despite being sought after for many years by Rafa and his sister, she never appeared before the two and granted Rafa the face he had sought after.

During 100 ASC, the Mother of Faces was approached by Aang who had been riding on her wolf. Enraged that somebody would use him as a "beast of burden", she demanded his name. In return, he asked for hers and she told him that she was the Mother of Faces.

Trivia

 * The Mother of Faces' abilities seem to parallel Koh's, who had the ability to take away faces.
