AVATAR AANG

Aang was born to two unknown Air Nomads in 12 BG, though the monks of the Southern Air Temple took him away after discovering his identity as the Avatar.^[9] As an Air Nomad, Aang traveled extensively around the world.^[10][11] During his childhood, Aang was housed, raised, and educated at the Southern Air Temple, under the guardianship of Monk Gyatso, who served as his father figure, counselor, and tutor.^[5] 

As a child, Aang was a member of the Air Scouts, where he learned essential skills such as how to tie reins to a bison's horns with the bison horn knot.^[12] During these early years of life, Aang had to pick four toys from among thousands, and chose the Avatar relics, proving himself to be the Avatar, even though he himself did not know it yet.^[13] 

When Aang turned six years old, he and several other young Air Nomad boys were taken to the Eastern Air Temple where they each chose a sky bison as their lifelong companion. Aang approached his soon-to-be pet sky bison Appa and offered him an apple, which Appa accepted, thus marking the start of their deep and lifelong friendship.[14]
