It's a beautiful Saturday at Hogwarts School of Witchcraft And Wizardry. The bright, afternoon sun was high in the sky, reflecting off the black lakes surface. Students covered the grounds, glad to have such a nice day before classes started on Monday. The forest seemed to dance with happiness, the tree's swaying in the breeze. Everything seemed perfect.

A petite girl watches all this with fascination from the second highest point in the Castle. Her bright blue eyes shine with laughter as she sees a boy with shoulder-length, black hair run across the grounds towards his friends. A very stern looking woman following him at a brisk pace.

"SIRIUS BLACK!" She hears Professor McGonagall scream, or, Minnie, as she had gotten into the habit of calling her. "HEADMASTER'S OFFICE! NOW!"

The girl chuckles and shakes her head, making her waist-length, dirty-blonde locks fly gracefully around her.

"Sirius seems to have made himself at home." A voice laughs next to her.

She turns to watch the white haired man watching the scene before him. Sirius seemed to be trying to talk his way out of his punishment.

"Only the second day and he's already getting under Minerva's skin." Albus Dumbledore chuckles.

Outside they could see Sirius being pulled up to the castle by his ear, his friends - and a few other students as well - laughing as they watched.

"Uncle Al?" The girl asks, demanding the attention of the man next to her. "Are you sure I'll fit in here? It doesn't seem to be anything like Durmstrang."

"No, it's not like Durmstrang, but I am most confident that you will fit in here, Katarina." A strokes his beard, his blue eyes, which were the exact same shade as the girl next to him, sparkling behind his half-moon spectacles.

"If you really think so..." Katarina (Kat) Dumbledore trails off, peering curiously at the man beside her. He gives her a firm nod and she sighs, walking over to sit in the chair in front of the Headmasters desk.

The Headmaster's office was one of Katarina's favorite places in the world, second only to her house in Paris. The beige colored walls were inviting and covered in portraits of all the previous Headmaster's of Hogwarts. Her favorite was Phineas Nigellus Black, even though he was normally very rude, he made her laugh.

One of her favorite things in the room was the instruments: there were tons of them. Some on tables, some hanging on the walls or from the ceilings, and a few of the taller ones sat on the floor. Katarina loved to play with them, see what each did, for they all did something different.

But her very favorite thing in the room was Fawkes, Dumbledore's Phoenix. He was a sweet bird who usually perched on her shoulder while she visited, which she did every chance she got. Although she would probably be visiting a lot more now.

Katarina had the reputation as a trouble maker at Durmstrang, which was a very strict school. She had gotten expelled for playing a particularly nasty prank on the Head Master, not to mention all the pranks she had played on her peers. And her Uncle, being the Head Master, had pulled a few strings and gotten her into Hogwarts for her last two years, provided she behaved herself.

"Are the people in Gryffindor. . .nice?" Katarina asks curiously. She had just recently been sorted into Gryffindor, seeing as Durmstrang didn't have the same houses. It had been a private thing; they decided it would be easier for her to already be in a house when she was introduced.

"Yes, they are very pleasant company. I have a feeling you will get along very well with The Marauders. They act very much like you did at Durmstrang." He said, smiling at her fondly.

"The Marauders?" Kat asks, looking skeptical.

Dumbledore raises his eyebrows, "Do you know them?"

"No, it just sounds like a lame as- I mean a lame name." Kat corrects herself, smiling innocently at her Uncle.

Dumbledore laughs, "You must give everyone a chance, Katarina. You never know what you could learn from someone."

"Yeah, maybe I'll learn some new pranks." Katarina grins, "Then I can try them out on Xavior."

Xavior was Katarina's older brother. He was 17 and in his final year at Durmstrang. Kat had 7 brothers, 3 older, including Xavior, and 4 younger. They were all a year apart, except for Jake, who was 8. Her parents had died when he was two, leaving Saunder, the oldest brother, to raise her and her family, with a lot of help from Uncle Al.

Dumbledore laughs just as a knock echoes through the room. "That will be Mr. Black." Dumbledore whispers to her, and then a louder,

"Enter."

Katarina's POV

"Enter."

The door fly's open and a handsome boy walks in, or, more like, saunters in.

"Hey, Dumbledore!" He says excitedly.

"Hello, Sirius." Uncle Al answers, "To what do I owe this pleasure?"

"Just fancied a visit!" Sirius says excitedly, walking across the room and plopping himself in the chair next to mine.

"Sirius, this is my niece, Katarina, she will be joining us in our classes this year."

"Nice to meet you, Katarina." he says, flipping his hair out of his eyes in an overly dramatic way.

"Nice to meet you, too, Sirius." I mock him, flipping my blonde hair out of my eyes the same way he did.

He grins.

"She has just been sorted into Gryffindor, and it would be wonderful if you could show her to Gryffindor Tower."

If possible, Sirius' grin widens.

"Sure, Dumbledore. It would be my pleasure." Sirius agrees. "Actually, I'll give her a tour of the whole castle!"

"Excellent." Uncle Al smiles, "Now, what did you really come here for?"

"Is it so hard to believe that I just wanted to see you?" Sirius asks, trying to look innocent.

"Yes." Dumbledore answers, his blue eyes twinkling.

Sirius huffs out a breath, making his hair fly out his eyes, "I hexed a Slytherin."

"Ah." Uncle Al sighs, "And what did Minerva give you as punishment?"

"Detention tonight and 10 points from Gryffindor." Sirius answers reluctantly.

"That seems sufficient enough. Now, I have some work to do, so you and Katarina may leave." Uncle Al dismisses us.

"Alright, see you later, Dumby. And don't worry - I'll take care of your niece!" Sirius waves and takes my hand, pulling me towards the door.

"Bye, Uncle Al!" I yell over my shoulder as Sirius drags me out of his Office.

"Ooh! I like that!" Sirius grins "See you later, Uncle Al!" Sirius yells.
