Zuko captures katara as she is the last remaining waterbender of the southern watertribe

An other worldly being lives among us. It have existed long before we began and will be here long after we end. It has watched us through brambles and bushes as we humans have developed over the ages. It doesn't understand our desire, our desire for luxurious houses. It doesn't understand our stubborn, selfish ways but when it is thrown into the mist of human war and hardship it understands one thing clearly. kill or be killed.
