YOU SAID:
Water. Earth. Fire. Air. My grandmother used to tell me stories about the old days, a time of peace; when the Avatar kept balance between Water Tribes, Earth Kingdom, Fire Nation, and Air Nomads. But that all changed when the Fire Nation attacked. Only the Avatar mastered all four elements. Only he could stop the ruthless firebenders, but when the world needed him most, he vanished. A hundred years have passed, and the Fire Nation is nearing victory in the war. Two years ago, my father and the men of my tribe journeyed to the Earth Kingdom to help fight against the Fire Nation, leaving me and my brother to look after our tribe. Some people believe that the Avatar was never reborn into the Air Nomads and that the cycle is broken. But I haven't lost hope. I still believe that somehow, the Avatar will return to save the world.
INTO JAPANESE
水。地球。火災。空気。私の祖母は私に昔、平和の時間についての物語を伝えるために使用されます。アバターは、水の部族、地球王国、火災国家、エア遊牧民の間のバランスを保ったとき。火災国家が攻撃するときしかし、それはすべての変更します。唯一のアバターは、すべての4つの要素を習得しました。彼は無慈悲なfirebendersを停止するが、ときに目ができたのみ
That didn't even make that much sense in English.
