A/N: Thank you guys for all the kind words :] Okay, to clarify TheRavenFlute, Aang and Toph are 12, Katara's 14, Sokka's 15, and Zuko's 16. So they're the same age as they are on the show :P As for the Harry Potter cast, they're Chamber of Secrets-aged, so there's some math there for you :] And yes, Ron and Hermione are in there but with smaller roles.

1: Toph

Toph frowned and rolled on the balls of her feet impatiently. The train ride had already put a damper on her mood: she sat alone the entire time while she listened to the happy chitters from the compartments around her. The only upside was that she brought nearly an entire cartload of sweets; the lady working the cart had laughed. Something about "Oh, another one this year".

And now, she had to wait outside the Great Hall with a group of obnoxious first-years when everyone else was already inside. The doors to the hall burst open suddenly. "Alright, quiet!" The voice was female and kind of old. She sounded like she'd done this a thousand times, like one of those weary day care teachers breaking apart a playground brawl. Yet her voice maintained a sort of... queenliness to it, that undertone where you know you have to listen to her. And the crowd did; they shut up immediately.

Toph decided she liked the woman, just for being able to clear her ears of the clutter coming from the kids around her.

"Welcome to Hogwarts. I'm Professor McGonagall. You may come to me in case of any questions. Now quietly, you will enter the Great Hall and be sorted into your houses. Do we have a Toph Beifong here?"

Toph perked up and raised her hand.

"You're a late addition, so you will be sorted first."

"Sweet!"

A stern throat-clearing from McGonagall shut her up. Without another word, the doors opened again and the students filed in.

2: Katara

As the doors to the Great Hall creaked open, Katara frowned. "I'll talk to you later," she whispered to Hermione before stealthily sneaking back to the Ravenclaw table. Fred and George fluttered their eyebrows and blew her overly exaggerated kisses.

Katara laughed, and then sighed. Being in Ravenclaw wasn't what she had wanted. The Sorting Hat, even, had had a dilemma between that and Gryffindor but ended up putting her in Ravenclaw because "that's where she would excel". She took a seat next to Roger Davies, who was probably her best friend in the house. All her other friends besides Aang were in Gryffindor: Hermione, who had taken on a little sister role... The twins... Oliver Wood...

She'd had a strange fascination with him lately. He was athletic, kind, charming, and cute. Sokka, however, had labelled him untouchable because they were best friends despite Oliver hating that Sokka was probably the best Keeper in Ravenclaw history. Their friendship always got really awkward around Gryffindow-Ravenclaw matches when their competitive edges kicked in.

"Stop staring." Roger nudged Katara, raising his eyebrows. "He'll figure it out."

Katara snapped into focus, realizing that she'd been ogling Oliver for the past five minutes. And that he was now looking at her with a slightly uncomfortable expression.

Roger nodded to him from across the hall and waved, trying to play down the situation. Oliver smiled and waved back, his gaze flickering from Katara to Roger.

"Thanks," Katara murmured under her breath.

"No problem."

Katara's eyes drifted over to Oliver again, until the train of first-years blocked her line of view. At the head of the crowd was a girl who lookd a little short for her age, with her black hair pulled up into a gigantic bun. What really caught Katara's attention, however, was the fact that even though she was obviously blind (cue pale eyes and and how she wasn't looking around in amazement like the others), the girl walked with a swagger that made her seem bigger, more intimidating. It probably also helped that she'd managed to wear the Hogwarts uniform like a delinquent, with the sleeves rolled up and dirtied, the shirt partially unbuttoned and very untucked, and the shoes scuffed and muddied beyond repair. She looked like Seamus did after an explosion.

Professor McGonagall worked her way to the front and as usual, introduced the Sorting Hat. The blind girl, Toph Beifong, apparently, was the first to be called up. "Oh, you were the one I missed last year! Hmm... A big temper you have there... Prone to violence and shortcuts... Very stubborn... Don't like rules, do you? But there's that bit of loyalty and honor to you..." A long moment of silence later, the hat boomed, "HUFFLEPUFF!"

Toph raised an eyebrow, shrugged, and then sauntered off the stage towards the cheering of the Hufflepuff table.

3: Aang

Aang beamed at the girl walking towards him. "Hi! I'm Aang! Sit here!"

She shot him a strange expression, but ended up sitting beside him. "I'm Toph."

"Cool! Are you excited to be here? Hufflepuff is pretty wonderful. Everyone's really nice."

Toph shrugged. "I would have preferred, you know, Slytherin or something. But at least y ou seem friendly."

They continued talking as the first-years got sorted.

"So how come you're here a year late?" Aang asked, readjusting his hat.

"My parents are really overprotective. They don't think Hogwarts is very... safe. And then the whole blind thing doesn't help either, especially since I can't read or write."

"Really?! You're blind?" Aang waved his hand in front of her face in amazement.

Toph's sightless eyes bored into him. "You. Are. An. Idiot."

"That's not very nice."

"I'm not very nice."

Aang sighed. "Well, I'm in second-year too, so we can be friends! I'll introduce you to some of my other friends and help you get moved in faster. Most of them are in other houses though."

"Cool. Who are they?"

"Well, there's Katara and Sokka in Ravenclaw. They're siblings. Katara's in fourth-year and Sokka's a year older."

Toph raised her eyebrows suddenly. "You have the hots for Katara?"

Aang's eyes widened and he leaned away, mouth pulling into a long line. "What?! Of course not! I mean-"

The blind girl let out a throaty laugh. "Don't worry about it. I've, uh, got some pretty well trained senses. I can tell when your heartbeat speeds up and I don't think you'd lie about her being in fourth year. So it must be a crush." With a triumphant smirk, cocked her head towards Aang.

"Shhh! Don't tell anyone!" Aang looked around nervously, waving nonchalantly at Katara when she shot him a confused glance.

Toph let out a loud laugh. "Okay, okay. But moving on, who else?"

"Then there's Harry who I hang out with sometimes... but not that much. We train together for Quidditch. Oh, the Weasley twins are hilarious! And then there's Hagrid."

"Who's Hagrid?"

"He's the groundskeeper. He takes care of a lot of the wild animals around here. OH! I can't believe I forgot! There's someone super important I need to introduce you to later."

Toph raised a brow. "Who?"

"A very close friend."

4: Zuko

Zuko looked enviously over at the Slytherin table where they were cheering at the addition of a young blonde girl. She looked almost exactly like Draco Malfoy, a family friend who Azula was expected to marry, much to her disdain.

"Hey, what's the matter?" Oliver Wood shot him a look of concern.

"Nothing." The feast appeared suddenly and Zuko busied himself eating. Oliver Wood was possibly his only friend at school. Of course, their friendship also gave Azula another reason to mock him.

"So," Oliver mumbled, as Quidditch-obsessed as usual, "Have you changed your mind about the team?"

"Maybe." That was always Zuko's response. The truth was, Azula was one of Slytherin's best Chasers. She was a Seeker in her first two years-fast-and only gave up the position to Draco because their father had ordered her to do so. Facing her was a lose-lose for Zuko. Losing meant even more goading from Azula, and winning for Gryffindor meant no chance of going home, ever.

"Seriously, you've improved a lot over the summer." Oliver took a swig from his goblet. "With you on our team, Gryffindor would be undefeatable!"

Zuko let out a snort and shook his head. "Azula's way faster than me."

"Don't even worry about her." Oliver rolled his eyes. "She doesn't take the sport seriously. She's only up there to show off."

"Leave me alone." Zuko tipped his head back and took a long sip, glancing at Oliver for a reaction.

"Hey, I know it's difficult. Don't take it out on me." Oliver frowned and held his hands out.

Zuko sighed. "You're a good friend."

"I know." The Keeper shrugged nonchalantly and then shot Zuko a grin. "So rethink that offer, would you?"
