then the fire nation attacked

Avatar the last air-bender opener line

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 100 years passed and my brother and I discovered the new avatar an Airbender named Aang and although his airbending skills are great he has a lot to learn before he's ready to save anyone but I believe Aang can save the world (cue Avatar music)
