Hey, Aang Where's Your Sister?

This is just a fun little story about if Aang from Avatar the Last Airbender had an older sister. This might stop at any time so be warned that I might drop this. This isn't the best version you'll ever find, but it's just something to pass the time. I do not own Avatar the Last Airbender, so do not quote me on anything. I do not know the storyline very well so this will be very off. If any of you are well versed in the Canon version, tell me what I got wrong and tell me how to change it. Thanks for reading and enjoy.
