After leaving the North Pole, Aang continues to learn and master waterbending with Katara. Aang, Katara, and Sokka look for someone who can teach Aang how to earthbend. They soon meet Toph Bei Fong, a young girl who is one of the best earthbenders in the world. She is blind, but knows how to "see" (or sense her surroundings) through earthbending and by feeling vibrations, or small shakes, in the earth. She teaches Aang to do the same.
