Prologue

*The image up top is what I like to imagine the reader wearing- Yes she has pants... i like pants*

Before the 100 year time skip

A teenager girl is seen sitting underneath a tree sitting criss-cross with her knuckles touching. With each breath she take the calmer she becomes. As she meditates she begin to think about her home and how she was able to stay with her brother, Aang. 

You see the Southern Air Temple is mainly filled with boys and men same with the Northern Air Temple, while the Eastern and Western temples houses females. When Y/n was 5 years old her little brother was born. She immediately had grow very attached to the small airbender and would not allow the anyone to separate them. So the monks decided to just take her with them to the Southern Air Temple, her and Aang both were under the care of Monk Gyatso.

Growing up in a temple full of boys was a little difficult for Y/n considering she was one of the only females there. As the years went by the young girl became a master airbender and she wore her tattoos with pride. Of course her little brother found it a little strange to see his sister bald but he always looked up to her. One day young Y/n decided to take some extra cloth and design her own airbending outfit. She wanted to feel unique and proud of her clothes. 

Now back to the now 17 year old Y/n meditating, as she sitting feeling the air around her she suddenly feels a shift in the air. She takes a deep breath and is able to feel what or in this case who was coming towards her. It was her younger brother on his air scooter coming straight towards her. As Aang pushed himself off the scooter to tackle Y/n, she stood up quickly and caught the now fully tattooed boy. 

"Aww. Come on! I was so close to getting you! How did you know I was coming?" Aang whined as Y/n held him up with her hand in his armpits.

As the teenager put the slightly dramatic boy down she spoke with a small smile on her face, "Well I listened and felt the air around me and suddenly I felt a very excited boy riding a ball of air coming towards me."

Aang looked at Y/n in amazement and said, "Whoa! That's so cool!" 

Y/n smiled at her brother and asked him, "Now, what did you need to tell me or ask me originally before you got distracted?"

Aang suddenly froze and his smile fell off his face, " The monks told me that I'm the Avatar and I don't know how to feel... I don't really want to be the Avatar."

Y/n eyes widened and she suddenly felt a bit bad for her brother. 'He only 12 and I know he still wants to live freely and have fun. But deep down I know he will be a great Avatar.' she thought as her brother had a small pout on his face.

~Time skip to that night (the night Aang ran away)~

As Aang climbed up onto Appa he didn't expect to see his sister sitting there with a small smile on her face. She said, "Where ever you go, I go. I know I should probably tell you not to go but I know you're scared. I will go with you anywhere because i promised Gyatso that I would always protect you."

Aang let out a breath of relief and smiled at his sister as a way to say 'thank you' and he takes Appa's rein and quietly says, "Appa, Yip yip."

As the two siblings flew through the air around one of the pole a violent storm suddenly hit making the two of them tighten their grip on Appa. They were tossed into the crashing waves and Aang's Avatar State activated sensing the danger. He surrounded them in a ball of air that then became frozen over.

Not to be discovered until a hundred years later by another pair of sibling.
