Please let me know what you think of this chapter! And, regarding Bellatrix, there will only be little hints about her until she breaks out of Azkaban, then she'll be in it a bit more :)

When they landed, they were in some sort of wooded area, surrounded by trees on all sides except one, where there was a tall, iron fence, leading out onto a row of grey, and rather dull looking terrace houses.

It took them a minute to get over the dizziness of apparating, before they stumbled out onto the street.

"I don't feel very well," Ariella muttered, clutching her stomach.

"Don't worry, you'll get used to it after a while. It's taken us years," George told her. "You could always have one of our puking pastels if you want to, you know, get it out?"

"She'll be alright, I think George," Hermione told him promptly and pulled Ariella away. "Where are we anyway?"

"The Order's Headquarters. 12 Grimmauld Place," Ron answered.

"But, there is no 12, for Goodness sake, Ronald! Are you blind?"

"Are you stupid? We're wizards–"

Suddenly, the houses started to rumble and shake, slowly moving apart to reveal another house and making the group jump.

"How did you–" Ron started to ask, but soon realised it wasn't any of his friends when he saw they were all staring at the row of houses in shock. Instead, he rephrased the question. "How did it open on its own? Mum was supposed to meet us out here when she got back from Diagon Alley!"

Before anyone could answer, the houses stopped rattling and the door to 12 Grimmauld Place opened.

"What are you all doing standing out here, gawping?" Alastor Moody's voice came from the doorway, his magical eye whizzing round at them all. It unnerved Ariella, who had never seen Moody in her life, and she clung to Hermione's arm.

"Who's that?" she whispered.

"Professor Moody!" Ron cried, answering Ariella's question.

"Mrs Weasley was supposed to meet us out here, but she hasn't arrived yet," Hermione explained.

"I see. Well, don't stand out there, go in. I just need to pop out for a few hours. Tell your mother that I'll be back for the meeting this evening."

"Okay, I will."

With that, Moody disapparated, leaving Ariella staring at the spot he had disappeared from.

"What was that?"

"What we just did, he disapparated," Hermione answered. "Come on, we need to go in before the houses move back again."

Ariella nervously followed her sister into the house, clutching at her arm as they passed through the narrow hallway, with the old wallpaper peeling off the walls and the people in the crooked portraits glaring at them.

"What is this place?" she whispered, as they passed a portrait which promptly attempted to spit at them.

"I'm not sure. It obviously belonged to some a dark wizarding family. I'll ask Ron later," Hermione answered.

"I'm not sure I want to know. I don't like it here."

"Well, you were the one who wanted to come to a wizard's house."

Stepping through the doorway at the end of the hall, Hermione was greeted with hugs from Mr Weasley, Sirius and Lupin.

"And this must be Ariella?" Lupin asked when all three men had stepped back. "Remus Lupin, nice to meet you."

"You too," Ariella said shyly. "But you can call me Ella."

"This is Sirius and Mr Weasley," Hermione introduced, pointing at the dark and ginger haired wizards in turn.

"Ron, do you want to take the girls up to their new room and let them get settled in? I'm sure they want to unpack before dinner and your mother will be home shortly," Mr Weasley said after everyone had been introduced.

"We'll take your bags," Fred and George offered, and without any answer picked up the suitcases and disapparated with a loud pop.

"They're driving your mother mad with all their magic," Mr Weasley commented, staring at the spot the twins had just been standing in, shaking his head.

"Alright, come on. I'll show you round the house." Ron said, heading out of the room and up the stairs.

"Ron, what is this place exactly?" Hermione called up after him as they passed several creepy looking house elves, their eyes following them from the glass tubes they were in, as they walked up the stairs.

"Sirius' childhood home. He inherited it from his parents because, as you know, his brother died."

"No wonder it's so creepy. The Blacks are very traditional. I suppose these house elves were a tradition too."

"It's disgusting," Ariella commented, wrinkling her nose. "Who would do that to house elves?"

"The Black's," Hermione and Ron both answered at once.

"One thing you will learn when you get to Hogwarts is that pureblood families tend to end up in Slytherin because they think they are better than half-bloods and muggle-borns like us. They think of us as inferior because our blood isn't as 'pure' as theirs," Hermione explained at Ariella's confused look.

"Right."

At the top of the staircase, Ron took them into a small, dark room. The dim lights only emitted enough light to see the outline of all the furniture so they couldn't bump into anything and they could just about make out two beds, a wardrobe and a dressing table with what looked like a mirror perched on top.

"What took you so long?" came a voice from the bed. Looking over, Ariella saw two shadows sitting on one of the beds.

"Oh, shut up. Just because you can use magic–"

"You're starting to sound like Mum, Ronnie-kins," the other shadow interrupted. Ron just glared at them. "Well, we'll leave you two to unpack, come on Fred."

Once more there was a loud crack and both shadows disappeared.

"Well, I'll leave you too. I'm just across the hall if you need anything," Ron told them and walked out of the room, leaving the two sister's to unpack their things.
