Aria is the daughter of Bumi, Aang and Katara's elder son. She gets her blond hair from her mother, a non-bender, but her blue eyes are attributed to her grandmother Katara and she is an Airbender like her grandfather Aang. She is Korra's age and met Korra a few times on visits to her grandmother at the South Pole. Aria does not have the traditional air nomad tattoos, as she has not yet reached master status. - A

"Aria!" Jinora, Ikki, and Meelo shouted as a sky bison descended onto Air Temple Island.

"Hey! How are my favorite cousins!" the bison-rider said, smiling and jumping down.

"Aria! Aria! Aria!" Meelo said, jumping onto the girl's back.

"Did it take you long to get here? How was the trip? Did you see anything cool? Wanna see a new trick?" Ikki said, jabbering away at a thousand miles per hour.

"Hi Aria, how've you been?" Jinora said.

Aria smiled, grabbing Meelo and setting him down beside his sisters, "Hey you three, I've been great! But look at all of you, you've grown at least a foot each since I last visited!" Her bright blue eyes looked at each of the smiling faces of her cousins.

"Aria!" Came a voice from the side of the courtyard. She turned to see Tenzin and Pema waving to her.

"Uncle Tenzie!" Aria said, dashing over, her long blonde braid whipping in the wind.

She hugged him tightly as he smiled, cringing ever so slightly.

"Pema! And baby too!" She smiled at her aunt, giving her an awkward hug around the baby bump, "It's so good to see you all!"

"I trust your father is doing well?" Tenzin asked, formal as always.

Aria smiled, "Yeah, Dad's fine, Mom tried to get me to bring a messenger hawk in addition to Eero, but Dad was able to talk her out of it."

"Hey, us mothers worry from time to time." Pema said knowingly.

"Is Korra around? I haven't seen her since my last South Pole visit four years ago." Aria asked excitedly.

"She is probably at the Pro-Bending arena just across the bay. Her team has advanced to the grand tournament and they've been training every day. Perhaps you can get her to come back for an Airbending lesson every once and a while?" Tenzin explained.

Aria laughed, "Sure thing, Uncle. I'm gonna go say hi but I'll be sure to drag her back for dinner, ok?"

Aria waved to her Aunt, Uncle and cousins before taking out her glider and flying to the pro-bending arena. Gracefully landing outside the entrance, she ignored the stares of the people around her and strode into the building. Realizing she had come through the ticketed entrance, she ducked behind a door labeled 'Staff Only.' After some wandering, she was sure she was lost. Just then, a man toting a mop and bucket came around the corner, "You lost, missy?"

"Uh, yeah, I'm a friend of one of the Fire Ferrets but I have no idea where to find them." Aria said, a little embarrassed – she could navigate the globe but there were no buildings this big and complex in her village.

"Oh, their training slot is over, but the boys live up in one of the tower apartments, so just follow this hallway to the stairs and go to the top." The man said kindly.

Aria smiled, "Thank you!"

She found the stairs without a problem and decided to just rocket up the center of the spiral staircase using her airbending. Jumping, she shot up the tower and landed softly in the apartment. There were two boys sitting next to Korra on the couch across the room, both with shocked expressions on their faces.

Korra jumped up, "Aria! It's been forever since I last saw you!"

The Avatar and the airbender hugged tightly. "How are you liking the city? This is your first time away from the south pole, isn't it?" Aria said, smiling wide.

"It's amazing! Oh, by the way, this is Mako and Bolin. They're on my pro-bending team." Korra said, gesturing to the two boys.

"Your pro-bending team? I seem to remember you asking to join us." Mako said, smirking at Korra and getting up to shake Aria's hand.

"I'm Aria. I'm an airbender." She said, shaking his and Bolin's hands.

"I-I'm Bolin." Bolin said.

"Wait, I thought the only airbenders left were the descendants of Avatar Aang?" Mako said, interrupting his brother.

"She's Tenzin's brother's daughter." Korra explained.

"And Korra here is my Grandpa." Aria joked before earning an elbow to the ribs from Korra, "I used to visit my grandma at the South Pole, where she lived with Korra."

"So what brings you to the city? I thought you were going to re-establish the northern air temple?" Korra asked.

"Yeah, I kinda need to reach master status before I can teach anyone. So I came here to finish my training with Uncle Tenzie," Aria said, smiling.

Korra narrowed her eyes, "That's not all, is it?"

Aria's smile faltered a bit, "And I may or may not have been asked to come to get you to calm down and focus on obtaining balance in your life…"

"Aria! I'm the Avatar, I'll get there on my own!"

"Korra, you know that's nonsense, every Avatar has to learn their talents from a bending master. Just because you could do some little tricks with earth, fire, and water as a kid doesn't mean you never have to sit down and learn something." Aria said sternly.

Korra grumbled and sat back down on the couch.

"Anyway, Korra, I promised Auntie Pema you'd be home for dinner, so please try and make it."

She waved goodbye before jumping out the window, releasing her glider as she fell and soaring off towards air temple island. Bolin watched as her red glider weaved its way across the bay.

"Stupid, goody two-shoes." Korra said.

"Hey, she has a point you know," Bolin said from the window.

Korra shot him daggers with her eyes, "What?"

"He's right, Korra. Aria's right. You know Avatar Aang had to find masters in each discipline and listen to them in order to master all the different types of bend-" Mako said but was quickly interrupted.

"I know the story! The stupid white lotus pounded that story in my head! I know I have to learn, I don't need everyone telling me!" Korra yelled.

"I appreciate that you spend your time training with us, but you can't neglect your duties as the Avatar." Mako said, frustrated with Korra's short temper.

Korra frowned and began storming down the stairs, "Why don't you run off to your whiny girlfriend, Mako?"
