Marianna Black: Wizarding Extraordinaire

Marianna smiled. She had never been in Diagon Alley before. She looked down her list and walked up to a man with flaming red hair next to a woman with bushy brown hair.

"Um, hello. Where's the Gringotts Wizarding Bank?" She asked politely.

"Just down the street. Large marble building. Can't miss it." the man smiled.

"Thank you!" She ran down the street until she came upon a large marble building. She fished a gleaming golden key from her pocket and entered Gringotts. She walked up to the counter and handed them the key. They led her down a mine cart track until they entered her vault. Her jaw dropped. It was full of Galleons and Sickles. She shoveled the coins into her bag and exited the vault. After Gringotts, she went to Ollivander's.

"Ah. Ms. Black. I knew it was a matter of time before my ancestors and I saw you in here. I believe 7 inches, swishy, and holly with a dragon heartstring core should work. Go ahead, give it a wave."

Marianna held the wand and waved it, feeling both idiotic and regal. A flowerpot lifted off the windowsill and landed softly in front of her. "It's 10 galleons, right?" she asked, plopping the proper amount of money on the desk as she walked out.

(Time Skip)

After Marianna finished all her mandatory shopping, she went to get an animal. She knew she'd get an owl, but what kind, that was unsure. In the shop, there were many screeches, meows, and animal sounds. She browsed the cages upon cages of owls, finally settling on a lovely barn owl with a beauteously defined heart shaped face. After paying for the owl, she left with the newly christened Gloria in a fancy silver cage. After getting an ice cream cone, she headed back to her room in the Leaky Cauldron.

(Time Skip to September 1st)

Marianna rushed out of the Leaky Cauldron with her trunks and Gloria in tow. She got onto the day bus and ran onto the Hogwarts Express. Taking an empty compartment, she flopped down on the seat. As the train started moving, a boy shoved open the door and tossed his trunk into the top compartment.

"Sorry, but there's no other open compartment, and the train started so suddenly." He apologized.

"Mm? Oh, it's alright. What's your name, anyways? I'm Marianna Black. You can call me Mary."

"Oh, I'm Albus Potter. Call me Al. Wait, are you related to Sirius Black?"

"Yeah. He's my uncle. Why?" Marianna asked.

"Oh, well, then I'm your god-cousin, seeing as my dad was your uncle's godson." Albus explained.

Marianna laughed. "I'm not sure that's how it works."

"Al? You in here?" a voice came from outside.

"Hide me!" Al whispered, ducking behind Marianna. She tilted her head questioningly, but didn't move away.

"Al?" Another boy leaned inside. He looked like a third-year. "Hey, have you seen a first-year boy in here?"

Marianna steeled her eyes and asked tersely, "Who wants to know?"

"Well, I'm James Potter the 2nd. I'm looking for my brother Albus. You seen him?"

She scoffed. "No, I haven't. Now get. Out."

James tilted his head and thought for a moment. "No, I don't think I will."

A tiny whimpering sound came from behind Marianna. "I knew it!" James exclaimed. "You were hiding him!"

Albus groaned and crept out of his hiding spot. "You two are brothers, then?" Marianna asked, bemused.

"Yup! Sons of Harry and Ginny Potter, godsons of Sirius Black." James boasted. "The only relatives of the Black family."

"Oh really?" Marianna asked. "Well, I'm Marianna Black, daughter of Regulus Black. True heir of the Black family fortune."

James looked appalled. Albus looked like he'd just won the Quidditch World Cup. "Well, there's Hogwarts!" James said, obviously changing the subject.

All three flocked toward the window. There they saw the magnificent castle rising on the horizon, with its tall spires brushing the clouds.

Sorry it was short. Please review; tell me what to add in the next chapter! I need to know which house she'll be in! I want to do either Ravenclaw or Hufflepuff, since Slytherin and Gryffindor get all the attention. Please alert me to any typos!
