Author's Note:
First of all, I'm NOT trying to steal anyone's idea. I know someone has already written about a zutara version to Phantom of the Opera, therefore, this story is NOT like that. Just because the title says so, doesn't mean it's gonna be like the movie plotline or whatever. So I'm NOT trying to copy anyone's idea!
The Blue Spirit,
Most wanted among the Fire Nation.
For the escaping of the Avatar.
He dwelt in a watch tower, alone he lay.
A blue mask he wore, hiding his image.
His identity shown in the light, kept secret in the dark.
Neither good or bad was he ...
For a girl would come along, to change him.
His personality, his views, himself.
