Chapter 1: An Owl at an Empty Dinner Table

Madeline Mender was exhausted. She had just spent the last several hours moving all if her clothes and eleven years worth of items and monster trophies from the Hermes cabin all the way to the Hades cabin without help. It wasn't like nobody wanted to help she just denied it.

She really should have told everyone that she had been claimed sooner, like right when she had gotten back from that quest in Ontario about a month ago, but instead she waited until she accidentally used one of her new found abilities during Capture the Flag. The particular ability was Cryokinesis. It had accidentally been triggered by her being startled by a particularly large deer and she had ended up freezing everything within five feet of her, which, of course, drew the attention of everyone.

Maddy was sitting against the outside of her new cabin, enjoying the cool breeze that made the extreme summer heat bearable. She was worried about losing her small handful of friends but she had to admit that the Hades cabin was very aesthetically pleasing with its dark walls and green torches and she'd, for the first time in her life, have a room to herself and the decor was very nice as well, in her opinion anyways. Her friend, Maude, however, hated it.

"Hey, Maddy!" Maude exclaimed as she approached, pushing her long, black side bangs out if her eyes.

"Oh, hey," Maddy stood up to face her much taller friend.

"Done moving?"

"Yeah, now I have some time to bask in this excruciating heat before dinner."

"I remember moving into the Hecate cabin." Maude's eyes sort of glazed over as she reminisced in the memory of the excitement of the day she'd been claimed.

"Yeah, I remember that too," Maddy nodded, remembering her friend moving in with her cabin mates at the unusually young age of seven.

"Probably everyone remembers. Anyways wanna watch me die a little inside while I try to control a raft?"

"Oh gods no. I'm never going anywhere near that river ever again."

"That is understandable, see you after dinner," Maude said as she walked away.

"Bye," Maddy weakly waved, it made her sad that they were growing apart, Maude was Maddy's closest friend and they had been friends since she arrived at the camp.

She went back into her cabin and grabbed one of her drawing notebooks, some pencils, some pens and a few boxes of coloured pencils, then she went back outside and began to find something to draw, eventually deciding to draw the camp activities director, Chiron, shooting an arrow from his bow.

Afterwards she went to dinner, sitting down at the empty Hades table. She offered up some of her food to the gods, adding in some extra to Hades.

As she was eating a large brown owl swooped down and perched in front of her, catching the attention of the nearby tables. Maddy noticed a yellowing envelope strapped to the owl's leg. Upon looking closer she noticed that her name was written in sparkling, emerald green ink. She slowly pulled the letter of of the nocturnal bird, apprehensive as it might bite her, and it flew away the minute the letter was no longer strapped to it.

Ms. M. Mender

Half Blood Hill

Farm Road 3.141

Long Island

New York

Maddy curiously stared at the letter, did all letters look like that? She didn't think so but she wasn't entirely sure. She opened the envelope which had a wax seal over the flap to seal it closed. She slowly unfolded the first of three letters.

HOGWARTS SCHOOL of WITCHCRAFT and WIZARDRY

Headmaster: Albus Dumbledore

(Order of Merlin, First Class, Grand Sorc., Chf. Warlock,

Supreme Mugwump, International Confed. of Wizards)

Dear Ms. Mender,

We are pleased to inform you that you have been accepted at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment.

Term begins on 1 September. We await your owl by no later than 31 July.

Yours sincerely,

Minerva McGonagall

Deputy Headmistress

Maddy couldn't say that she believed the letter but she couldn't say that she didn't believe it either. She unfolded the second letter, finding a list of things she would need to go to Hogwarts. Then she opened up the third and final letter. A smaller piece of paper that Maddy recognized as a train ticket fell out of the letter and she set it aside with the other two letters and began to read

In order to retrieve your supplies go to London and find the Leaky Cauldron, through which you can enter Diagon Alley to purchase your supplies. Inclosed in this letter is a ticket for your train. In order to get to Platform 9¾ you must walked between Platforms 9 and 10 at King's Cross Station.

Well, looking for the Leaky Cauldron wouldn't be too hard, all she'd have to do is shadow travel to London and search for it. She'd probably be exhausted after traveling but she would probably find a place to stay while regaining strength. Hopefully she wouldn't end up in Russia like the last time she tried shadow traveled a long distance, she tended to over shoot her her destination according to the many times she had practiced before telling everyone that she had been claimed. She'd probably have to be out for several days.

After all of the camp activities were over Maddy and Maude met up and chatted by the arena where Clarisse was practicing with a few other Ares kids. They didn't talk for long and when they were done Maddy went back to her cabin, grabbed a small leather pouch full of Drachmas, another one full of regular currency for the mortal world, as well as a sketchbook, some pens, pencils, some books, the letter and some supplies to light a fire so she could offer up food to the gods, which she stashed away into a bag, an old green one that was probably related to the military in some way based on it's size and the shade of green it was. She prefered this bag to her Camp Half Blood bag when she was leaving the camp because people would occasionally ask her what 'CHB' stood for and the closest thing to something believable she had ever come up with was Camp Howling Buffboon -'Buffboon' was the result of her tongue getting stuck between saying Baboon and Buffon-. She pulled on a dark, knit sweater and a hat just in case she ended up somewhere cold and then grabbed her bag.

She began to concentrate on the Leaky Cauldron, hoping that she wouldn't appear in the middle of a large group of people or in the middle of a street.

Suddenly, Maddy felt extremely worn out and and she opened her eyes to find herself in a sort of alley that was pitch dark. If she remember correctly England was about five hours ahead of new York time so it should've been about 3:30 in the morning if she was even in the right time zone. Upon closer observation she realized she was in a sort of courtyard behind a building, she checked the door of the building and found it open.

When she entered she was met with the smell of alcohol and food as well as the sound of drunken laughter and loud snores. She was in a pub.

Maddy took advantage of her control over shadows and used it to hide herself as she made her way through the bar, it was hard but that was the easiest power she had and she needed to get out of the pub unnoticed. She managed to get out of the pub and stepped out of the shadows. She turned around to face the pub she had just exited to find that it was named the Leaky Cauldron. She cursed under her breath as she had just wasted some of her energy on an unnecessary action and entered once again.

She walked straight to the bar where a man behind the bar was serving a woman a plate of food and a goblet of a steaming liquid.

"Excuse me," She said to the man. "I've been given a letter for Hogwarts and there are instructions on it that say I need to go to Diagon Alley and I'm not sure how to get there."

"Oh, a new Hogwarts student!" The man exclaimed. "It's rather late, all the shops are closed. What are you doing out so late anyway?"

"Oh, um, jet lag," Maddy said quickly. "I just got here from America. It's about 10:30 where I came from."

"Shouldn't you be going to the American school?"

"Apparently not, I've got a letter for Hogwarts." Maddy shrugged, then yawned.

"You can rent a room for the cost of ten galleons."

"Is that magical currency and can I get it at a money converter at like an airport?" Maddy was really hoping she wouldn't have to do anything that actually involved doing things.

"No, you can't get wizard money from the muggle world. Gringotts is still open, though, they're always open. There's also a muggle to wizard currency converter there as well as some money that Hogwarts provides to those who didn't grow up around magic," the man explained.

"Oh," Maddy sagged a bit at the thought of trying to find anything. "Is there a way I could stay here tonight and pay tomorrow? I'm really tired." As if to emphasize her point, she let out a long, almost soundless yawn.

"Of course, just come back here after you get your money and pay the fee. I'll get you a key for a room," he bent down and stood back up a minute later with a bronze key in his hand. "Here. Your room is number 14 and the rooms are just up the stairs." He pointed to the stairs in the corner near where Maddy had originally entered.

"Thanks," she took the key and slowly trudged up the stairs. When she entered her room she lazily threw her bag onto the floor and collapsed onto the bed, falling asleep before her head hit the pillow.

Maddy woke up to the sound of being yelled at. A voice that she hadn't heard before was yelling at her to get up.

She sat up to get the yelling to stop and see who it was who had been yelling and realized that, while she was mentally very much awake, she was still physically very tired she felt as if she had just carried a thousand pound bag all the way across Camp Half Blood without help and it was agonizing.

"Ah, you're finally awake," the voice that had been yelling at her before said. Maddy quickly looked around but didn't see anything that could talk. She slowly swung her legs around off the bed and stood up, grimacing as it felt like she was slinging sledgehammers every move she made.

"Who's talking?" Her voice came out raspy, as it did from time to time when she woke up still tired, she quickly cleared her throat. She looked around the room once more and saw that it was still dark outside and then moved on to look some more. There was nothing in the room except the bed, her bag, a dresser and a mirror.

Perhaps something was hiding in the dresser? She opened the each of the drawers. Nope.

Maybe behind the mirror. As she tried to pick it up something said, "Why're you picking me up? What're you looking for anyway?"

"Oh, it was the mirror talking?" Maddy asked.

"Of course. What else would be talking? Have you never seen a talking mirror before?"

"No, I have. I'm just very tired." She briefly remembered a few years ago when Maude had managed to enchant one of the more annoying children of Aphrodite's mirrors to shoot snide remarks at whoever was using it.

"Well, you shouldn't be. You were asleep for nineteen hours!" So it was about ten at night.

Maddy scowled at the mirror, grabbed a tiny chunk of Ambrosia and threw it into her mouth so that her body wouldn't be so exhausted. A small smile crept across her face as the taste of caramel spread throughout her mouth and her body became less heavy. She then grabbed her bag and ran out of the small room, down the stairs and to the man who helped her the previous night.

"How do I get to Gringotts and Diagon Alley and when do the shops close?" She quickly asked.

"I have to show you how to get into Diagon Alley, which is where Gringotts is -its a big, white marble building. Impossible to miss it- and most shops close in an hour."

"Okay, show me," Maddy said impatiently, the man nodded and walked to the door that led behind the Leaky Cauldron, then went over to the brick wall and tapped out a pattern. The wall opened up into an archway, revealing a long street bustling with people. Maddy quickly thanked the man and ran down the street, thankful that she was thin and extremely agile so she could just slip right between the people.

She stopped at a huge building made of white marble, like the man had described to her, with a small man in a scarlet uniform standing outside of it. Maddy assumed he was some sort of goblin, she'd never seen one but he sort of matched the description. He opened the large doors and Maddy found herself facing another set of doors.

These doors had a plaque on one of them reading:

'Enter, stranger, but take heed

'Of what awaits the sin of greed,

'For those who take, but do not earn,

'Must pay most dearly in their turn.

'So if you seek beneath our floors

'A treasure that was never yours,

'Thief, you have been warned, beware

'Of finding more than treasure there.'

Maddy might have found this warning rather ominous if she had not grown up around the prophecies that the Oracle of Delphi spat out from time to time. She opened the doors and entered the large building.

The ceiling was rounded and reached far too far above the ground and it was filled with goblins doing a variety of tasks, some were weighing different types of stones such as rubies and gold, some were filling out paperwork and some were counting coins -Maddy noticed three types, a large gold type, a slightly smaller silver type and an even smaller bronze type.

There was one goblin who was seeing people, a short line of one person stood in front of them and Maddy walked over there. She waited a few minutes until the person ahead of her was led away by another goblin named Griphook and stepped forward as the goblin barked out a sharp 'next!'

She stood on the tips of her toes and even then could only just barely see over the edge of the tall podium the goblin that sat at it. "I heard that Hogwarts provides money for first years."

"Name."

"Madeline Mender," she said, still trying to see over the podium and saw that the goblin had grabbed a large book and began to scroll through it.

"There's no Madeline Mender."

"Oh, but I don't have any wizard money."

The goblin pulled out another, even larger book with the letter 'M' engraved in the front and he flipped through it, then said, "Says here your mother works for the Ministry of Magic and you're a pureblood. Hogwarts doesn't supply money to those with live magical family members."

"Is there somewhere I can convert my non-magical money into wizard money?" Maddy asked, hopefully.

"Yes."

"Does it take American dollars?"

"Yes."

"Where is it?"

The goblin pointed to a section of goblins who were all weighing coins with stones then harshly snapped, "Next!"

Maddy walked over to the section and said to one of the goblins, "This is where I can convert money, right?"

"Yes," the goblin replied. "Hand over the money you wish to be converted."

Maddy handed over her small bag of American money and he dropped it in his scale, messed around with it quite a lot then handed Maddy a different sack of money.

"Thank you," she said as she took the sack and left the large bank. She pulled the letter out of the pocket of her baggy pants and quickly skimmed it, deciding to get a wand first.

She entered a small shop with 'Ollivanders: Makers of Fine Wands since 382 B.C.' written on the window. She was greeted by the tinkling of a small bell and an old man with pale, wide eyes that reminded Maddy of moons that she found it rather eerie.

"Good evening," he said in a soft voice.

"Uh, hi," Maddy replied a little awkwardly.

"New Hogwarts student?" He asked, though he seemed to already know the answer, she suspected this man was Ollivander.

"Yeah."

"Name?"

"Maddy Mender."

"Are you related to pureblood Menders?" He asked curiously. "I believe only one of them is the correct age to have a child at Hogwarts and she does have a daughter starting her seventh year. Eleanor and Alexandria."

"I don't know, I haven't met any of my family," she shrugged. Sure, she'd met Hades once but other than that, her statement was completely true.

"A shame, now, which is your wand hand?"

"I'm left handed."

"Hold out your left arm then," Ollivander said. Maddy did so and he flicked a long, lightly coloured stick -probably his wand- and several tape measurers began to fly around her as he continued to talk while flitting around the shop, going to each of the large bookshelves and pulling out small, thin boxes. "Every Ollivander wand contains a powerful magical substance. Unicorn hairs, dragon heartstrings and phoenix tail feathers are used most often, as well as a variety of woods. No two wands are the same, just as no two magical animals or trees are the same, so, of course, you won't get good results from another wizard's wand."

Suddenly the tape measurers curled up and flew back to where they had been originally placed as Ollivander stepped over to her with a stack of wands.

"Try this. Aspen, unicorn hair, 12 inches," he opened the top box and handed a slim, pure white wand to Maddy. "Go on. Give it a wave."

She did and a green fire suddenly lit up on the floor, almost burning one of the many shelves before Ollivander extinguished the fire.

"Not that one," he snatched the wand out of her hand and replaced it with another lightly coloured wand, this one had an intricate handle. "Ash, unicorn hair, 11⅔ inches."

This time a vase burst and the process repeated several more times until Ollivander handed her a black wand -obviously painted- with thin white designs intricately painted on, made of yew and dragon heartstring at 10¼ inches. She waved it around and purple sparks flew out of it in a gentle shower.

"A good wand indeed, I hand painted it about three years ago. It can be temperamental but it is quite strong." He walked over to the counter and said. "That'll be seven galleons."

Maddy put the dark wand down on the counter as she pulled the small bag of wizard money and opened it up.

"Galleons are the gold ones," he said and Maddy quickly pulled out seven of the gold coins.

Maddy made her shopping experience go by as quickly as it could -although she did stop to get a dark screech owl that she named Melinoe- and she went back to the Leaky Cauldron, payed the man who worked there and had a short conversation with him after she ordered some food, some of which she threw into the fire that was lit in the pub, where she learned that he was named Tom. Afterwards, she left the Leaky Cauldron, found an empty area and shadow traveled back to Camp Half Blood.

But of course she didn't have the luck she had when she was going to the Leaky Cauldron and ended up in somewhere in South America. She tried a few more times, getting closer each time until she popped up back in her cabin, thoroughly exhausted.
