Hey guys! This is a new story here, in which a young witch meets the Doctor. I would like to claim that both the Harry Potter series and Doctor Who are not my work and belongs to J K Rowling and BBC respectively. Now, let's get started!

Chapter 1: A Familiar Greeting

She saw the grey haired man gave a horrible scream and fell to his knees, then collapsing on the ground in a heap, dust settling around him.

"NO!" A voice shouts. It was her own. She felt herself rushing to the man and stalling herself in front of him, feet apart, wand out and ready. "Get back! GET BACK, I SAID! Expecto Patronum! EXPECTO - "

Before she could do anything else, however, a shaking sensation filled her. She felt herself falling on her knees the same way, strength weakening -

"Hannah, I swear to Merlin's polka-dotted underwear, if you don't wake up right this moment I will literally break your badge in half." A familiar voice said above her face as the shaking sensation continued.

Hannah opens her grey-blue eyes and see herself face to face with a younger, blonde girl with lighter blue eyes sparkling with frustration. Lora, she remembered, was her name. A fellow Hufflepuff prefect, a year younger than herself, who was a seventh year and about to graduate. Still didn't know what to do once she's out of Hogwarts, though.

"What time is it?" She mumbled sleepily, wavy locks of brown hair resting on her shoulders, even though she knows full well that she wouldn't be able to get more sleep. She remembered that she had the same dream again, for the tenth night in a row. However, like always, she failed to remember what it was about.

"Time for you to get your behind out of bed, you waste of a prefect." Lora literally hauled her up into a sitting position. She was strong for her age, but looks surprisingly innocent. "Saturday patrol duties, you brown banana. You've been a prefect for three years and yet you still don't know when to get up."

"You're an annoying little brat." The older Hufflepuff reached for her black and yellow uniform hanging from the top of her four poster bed. "Get out, I'm changing." She gave one last word before reaching up and drawing the drapes shut, sealing herself in darkness.

(Line Break)

The yellow prefect badge pinned proudly to her chest, Hannah strolled through the vacant corridor, a whistled tune echoing back to her. Usually occupied classrooms were deserted, desks sat quietly, as if they could be anything but. Well, it's Hogwarts, one may never know when a piece of furniture would suddenly starts dancing. All were unoccupied, except -

A flash of royal blue caught her eyes as she passed through a Defense Against the Dark Arts classroom, almost empty except for a tall blue box sitting in the corner, looking almost innocent but clearly not so - no, this must be a muggle artifact, for what else would say "Police Public Call Box" in front?

Hannah cautiously stepped into the classroom and made her way around the desks to stand in front of the mysterious blue box. The light inside was on, and the silhouette of a shadow was visible on fogged windows. Someone was inside.

She gingerly lifted her knuckles and rapped cleverly on the wood, causing a hollow sound. The silhouette moved and increased in size as its owner approached the door. Hannah backed up a few steps before one of the double door swung open to reveal a strangely familiar man with messy gray hair and a pair of eyebrows that made him always look angry and fairly like a hawk. Standing straight, he was half a head taller than hannah.

"What year is it?" He demands with a scottish lilt.

"1987, sir," She answered. At Hogwarts, no question was a strange question. "But if I may ask, What were you doing with that?"

Hannah raised a hand and pointed at the Tardis. The strange man turned and stared as though he didn't know it was there.

"That's my box," He turned back around and stated.

"I know that, sir. What were you doing inside of it?" Hannah followed.

"Oh, uh -" The man stuttered. "Nothing. Nothing at all. I'll just, umm..."

With a turn of his polished heels and a swish of his black jacket (to reveal red linings), he marched right back in the box, and then slammed it shut immediately. Footsteps could be heard from the inside, then suddenly a strange sound of metallic wheezing filled the room, and the blue box began to grow fainter and transparent. But as if it realized what it was doing, it began to become opaque again. When the noise finally stopped and the blue box was solid, the doors swung open once more.

"WHAT?!" The grey haired man bellowed, as though he expected to be somewhere else. Eyes passing right through the Hufflepuff, he slammed shut the box again. Muffled yelling could be heard from the inside.

"WHY AM I STILL HERE? THE HELL YOU MEAN YOU CAN'T GO ANYWHERE? WHAT"S WRONG WITH YOU?"

A bit intimidated, Hannah raised her fist to knock again. Barely a second later, the grey head popped out another time.

"What do you want?" He said shortly.

"You can't apparate within Hogwarts." She told him.

"What?" The man was confused.

"That's a teleportation device, yes?" The man was increasingly confused, and Hannah continued. "You can't teleport within Hogwarts by any means."

"What the hell is Hogwarts?"

Now it was her turn is confused. She furrowed her brows and cocked her head to one side. "Why, the official school of the British Isles, of course."

The man gave one aghast look before disappearing back into his box. Once again, muffled yelling could be heard from the inside.

"YOU BROUGHT ME TO A SCHOOL?! FULL OF CHILDREN?! YOU KNOW HOW WELL THAT'S ENDED UP BEFORE! WHAT THE AKHATEN DO YOU MEAN?! WHAT IN THE NAME OF RAXACORICOFALLAPATORIUS DO YOU THINK YOU'RE DOING, YOU MALFUNCTIONING OOD?!"

That string of words were full of loud, creative swearing that Hannah had never heard before, and that's saying a lot for a prefect. After a few more yelling and sounds of banging on metal, the grey head emerged.

"Where, in geographical terms, am I, exactly?"

"We don't know where exactly, but Hogwarts School of Witchcraft and Wizardry is somewhere in the vacant areas of Scotland." That was what prefects were taught to respond with in case of lost and confused travellers, but none had used it before now.

"What?" The stranger says.

"I said you're in -"

"Hogwarts school of what?"

"Witchcraft and Wizardry," in response to his flabbergasted look, Hannah continued. "Y'know, where kids come to learn magic?"

He just gave a disbelieving chuckle and said, "No."

"Sir, you literally just tried to use a device to apparate inside Hogwarts, don't try for one second to tell me you've never seen magic." Hannah was getting really tired of his bullcrap.

The man looked back, looking as if trying to come up with another valid explanation for the attempted disappearance of his box.

"That's not magic," He said slowly, "That's science. A little bit of extra science, too."

Hannah threw up her hands in exasperation. "Sir, if you're going to insist you're not magical I'm going to have to report you to my superiors." Then she suddenly got an idea. Her half blood mother had told her before about muggle books with the most creative topics. She had even read one about a mad scientist and thought of it as nonsense. Surely they could have just restrained him with a little bit of "extra science"? But thinking in "scientific" terms, surely it was possible for a muggle to just -

"Are you one of those Muggles - that's what we call non-magical people - that developed advanced technology like teleportation studying your 'science' all day?" It seemed a far stretch, but it was the best explanation Hannah could come up with.

"Er, um..." He looks back and his police box again like making sure he actually could apparate with that. "Yeah, that sounds close enough."

"Oh, ok." Hannah was relieved. That about explained everything that happened, and so she could just get the help of Professor Dumbledore to get the man and his box outside, where they could just teleport away. "So, if you would come right this way, please..."

She started to lead him away, but before they could even get out of the classroom, a Slytherin with sandy hair walked in, his wand out.

"Oh hey, Elliot," Hannah greeted him. He's the Head Boy this year, chosen from last year's prefects. No one wondered why. He was quick and intelligent, and was a prominent member of the duelling club. His perfect grades were only a fraction of his superiority.

"Hannah, I heard yelling -" Elliot started, but was cut short as his eyes widened in fear. Backing up until he was against the wall, he raised his wand and pointed it at the man behind her.

"You!" He gasped, looking as if he's seen a banshee.

"Uh, Elliot, this is - "

But Hannah was cut short when a jet of blue flames shot towards her. She conjured a shield just barely in time, blocking the spell so the the fire rushes to either side of her. Behind her, the man backed up a few steps.

The hexes kept coming. Hannah conjured shield after shield after shield, but she was being pushed backwards. Not many could defeat Elliot in a duel, and Hannah certainly wasn't one of them. Finally, she's had enough.

"Petrificus Totalus!" She shot a spell right back at Elliot, then conjured a magic barrier while he's taking the time to block it. They both stilled, heavily breathing.

"What in the name of cracker crumbs in Merlin's glorious beard are you doing?" Hannah cursed in the most creative way she could, earning a stifled chuckle behind her.

"You don't understand! That man's tried to kill me once!" Elliot gasped out.

"He's a muggle."

"Oh yeah? Then what's he wearing?" Elliot questioned sarcastically.

She looked back at the man. He lifted up his arms to show her his three button black woolen coat, just a little longer than a jacket. Red silk linings were found inside, in contrast to the black coat and white collared shirt, giving him the look of a stage magician performing for children, or perhaps a fashionable wizard, if one were to have no idea of muggle culture.

"He's a stylish muggle," Hannah improvised. "Your pureblooded arse wouldn't know."

That was the final straw for Elliot. A strong blast broke the shielding charm, which flickered and died. Another came soaring in the shape of a hawk, and Hannah didn't have time to block it before it slammed her backwards, making her fly off her feet straight into the grey man and knocking both of them into the blue box, hitting a cold metal surface.

The first chapter is done. Can you guess which Doctor Hannah just met? Please like or follow if you enjoyed this, and please leave a review if you want to express your opinion. I plan on posting once or twice a week, given the amount of things I want to put in one chapter. I do intend for this to be a finished work - I have the entire plot down, in fact. If everything goes well, I will post again soon. I hope I will see you then.
