Random Quote:
"Water, Earth, Fire, Air. Long ago, the four nations lived together in harmony. Then, everything changed when the Fire Nation attacked. Only the Avatar, master of all four elements could stop them. But when the world needed him most, he vanished. A hundred years past and my brother and I discovered the new Avatar, an Airbender named Aang. And although his airbending skills are great, he still has a lot to learn before he's ready to save anyone. But I believe, Aang can save the world."
Woo. Did all that from memory and only checked the real quote to see if I was right when I was done. Only missed one "and" and had put "peace" instead of "harmony".
Yes, I love Avatar: The Last Airbender.
