Tribe: Air Nomads
Occupation: Sifu
Weapon of Choice for Occupation: A fan
Likes: Speaking in dialects, playing pranks (getting pranked), making the older monks squirm, people who like to laugh, non-conforming (She got the tattoo...that's about as far as it went), flying bison (Amati), sweet foods, pretty much everything else besides what is listed below.

Personality: Bubbly, sometimes stern, always has a smile.

Story:
Always ready with a smile, Sariaj greets her class daily with an enthusiastic "GET YOUR BUTTS IN THE AIR!" To which her class responds by doing acrobatics with air bending. She believes that all you need to do is act, "As if" and it will come true. A philosophy that's helped her through a great ordeal.
An air nomad orphaned by a fire nation attack on the Northern Air Temple, Sariaj learned quickly of hate and pain. She stole away from that temple, leaving it to be destroyed (a regret that will be with her forever...along with a rather nasty scar across her back), and made her way to the Southern Air Temple where she was taken in by the monks.
She devoted her years to learning ancient dialects not heard in ages, and in disguises so that she would be able to spy upon enemies and allies (got her into many a tight spot with the older monks). She was very much against getting the tattoo on her head, and she clearly shows her distaste for it by covering most of it with her hair. She would only allow her head to be tattooed (for fear of the monks seeing the scar upon her back.
She smiles as much as she can, and her smile is contagious. Because of the hatred towards the Fire Nation because of her loss, she developed a second personality, which comes out when she needs to be merciless...and she can be. She will teach anyone who is willing to learn, regardless of tribal origins, and she values education at the top.

Hobbies: Pranks, collecting strips of fabric from different places.
