Avatar Korra

In short, it all seems to be happening, back when Korra was younger and didn't get to the city where Tenzin lives and back when he had only one daughter Jinora, you are a very poor child, without parents and a home, you live on the street, so you try to find a job but because this is a big city no one wants to take you in because you are very thin and weak, so you ended up in the wind tower where Tenzin, his wife Pema and his daughter live, this building has some guards because Tenzin is only one wind element right now, and because he is a big guy in this city, so you get to this Island and you get captured
