As she dyed her red hair into her typical shade of sea-foam green, the Tooth Fairy sensed that two teeth were ready to collect. Both in Britain. She finished her fast and teleported to Little Whinging, Surrey in England. The closer she came, she realized both teeth were in the same house. She then realized, as she found herself in a very ugly living room, that the two teeth were in separate rooms. "Mm, looks like I deal with siblings again,", she mused. Flying up the stairs, taking in the look of the house. Solid middle class, that's as clear as her teeth. "I wonder if these two are twins? Would explain why they lost their first baby teeth around the same time." Not because that is a twin thing. She just saw in her eternal life many parents forcing twins to do the same, even loosing teeth. She hates those parents. As she collected the first boy's teeth, she was met with a room overflowing with toys and a bed overflowing with boy. "O great, another of those."
She then moved to the second tooth she sensed. Going down, she stopped in front of the cupboard of the house. The cupboard. She couldn't comprehend why she senses a tooth in there. Especially since she can sense the tooth does not belong to Dudley Dursley. She sighed and opened the door, her magic allowing her to just open any door. To say she was shocked won't do the situation justice. The tooth fairy found a tiny boy, curled up in some worn out blankets in the cupboard. Picking the tooth off from a shelf – he apparently had no pillow, at least she won't call that piece of fabric a pillow – she left him a whole pound and left, alarming Jorgen von Strangle of a potential child in need of fairies.
While her main job is to collect teeth, part of the job is to take note of any kid in need.
Jorgen loves the Tooth Fairy – everyone does – but that doesn't change that he was frustrated to be woken up so early. But he knows too well there is only one reason for her to wake him up around this time. He sighed, "Who is the kid?"
"Harry Potter, situated in Little Whinging, Surrey, England," she answered. "Isn't that the kid from that one prophecy?"
"Yes..." He sighed again. "That can not wait until tomorrow. You continue your job, I need to fetch two fairies."
"Oh, you plan to give him two?", she asked surprised. As there were only finite fairies but so many children, Jorgen tries to give out solo fairies. Couples are only given to serious cases.
"Of course! Not only that, there will be a few changed rules for Potter," explained Jorgen. "I need to make an edited version of Da Rules. Now leave."
"Okay, okay. I'm on my way."
Harry was once again with Mrs Figg, he was glad he wasn't with the Dursley's, who were on a vacation. Mrs Figg allowed him to take his money – he still has no idea where it came from – and get an ice. Something the Dursley's never allowed! In fact, they would have given his mysterious pound to Dudley after accusing him to be a thief. His stay with Mrs Figg was a good opportunity to use the money, so he hid it until they left him and Mrs Figg's door.
On his way back though a tunnel, to flying figures popped up. Somehow knowing his name. "Hello Harry!" He flinched at their appearance and dropped his ice. He would cry if he wasn't used to dropping ice due to his cousin.
They flew to him, giving Harry a closer look. The female looking thing had pink hair and eyes and wore yellow, while the male thing had green features. As they just floated there, he asked, "What are you? How do you know my name?"
"My name is Wanda, his name is Cosmo," said Wanda. "We are fairies and from now on your god parents."
"That means we fulfil your wishes to make your life easier," added Cosmo. "Albeit we have to apply to some rules."
"What rules?" Harry knew that was too god to be true.
"You can't wish for love, to end someone's life and we need to be kept a secret.", explained Wanda. "Well, there are more, but these are the three most important ones."
"Does that mean I can wish for new Ice Cream?" asked Harry.
"What flavour?" countered Cosmo.
"Vanilla."
"How boring! But it is your wish."
"Cosmo!" said Wanda annoyed. She then fulfilled his wish, replacing the dropped ice with a cone and three scoops, more ice than he had before.
After he had eaten the ice, they returned to Mrs Figg's house. Cosmo and Wanda took shape of two pins. As Harry walked in, he muttered, "I wish the smell of cabbage was gone." As soon as he knew it, the smell vanished.
After a week, Harry had acclimated quite well to the two and their bickering. Cosmo and Wanda hid themselves as spiders. Blending in with the spiders that normally appear in his cupboard. Soon he was comfortable enough to tell them – with the Dursley's out of earshot of course – about the mystery pound. "Do you know anything about it?" Harry's logic was that magic must be real if these two float in his cup board. "Is the Tooth Fairy real?''
"She is.", answered Cosmo. "Now, that cupboard is small. Could you wish for us to make it bigger?"
"But the Dursley's would notice!", countered Harry.
"We could make that the door opens to an extended room for us but to the normal cupboard to your relatives.", proposed Wanda.
"Okay! I wish you do that."
Nearly five years passed, when the letters came. In his enchanted cupboard, he wished, "I wish I could get one of those letters!"
Wanda fulfilled it. As it appeared in her hands, she saw the wax seal. "Oh-ooh, a Hogwarts letter."
"What is Hogwarts?" asked Harry confused by the word.
"Good thing that the statue of secrecy doesn't count for us!" said Cosmo relaxed. "Well, we should be proof for magic, don't you think?"
"Yes," answered Harry. "So Hogwarts is magical?"
"Exactly, kiddo. You see, wizards and witches are real. They live hidden from the mundane world," revealed Wanda. "Considering you got this letter, it seems like you're a wizard, Harry."
"Congratulations!" said Cosmo, summoning a cannon with colourful sprinkles. Good thing Harry wished for the cupboard to be sound proof.
"Well, Hogwarts is a school for magic," explained Wanda further. "Oh my, Cosmo! We hadn't had a kid attending Hogwarts in centuries!"
"To be fair, we rarely take care of magical kids to begin with," he added. "This will be so exciting!"
Harry took a while to process the news. Judging by their reaction, it was a big deal. And good news. When the rarely have magical god children, does that mean magical children are more happy with their lives?
"What now?"
"We answer the letter... you want to attend, right?" was Wanda's answer.
"You would be away from the Dursley's," pointed Cosmo out. "And you kinda have to."
"Cosmo? What do you mean? Or last magical kid didn't!"
"Yes, but they got homeschooled by relatives," countered Cosmo. "Harry would just become an Obscurial."
"Right..." She then wrote a letter. "Mm, should we request someone to introduce you to the magic world and get your school stuff? Or should we?"
"We don't need help," decided Cosmo. "And I don't trust Dumbledore."
Wanda rolled her eyes. "As if you're still angry at the headmaster for beating you in that knit competition. Wait, we need help! We don't have his vault key."
"Can't he just wish for the materials?"
"That would be suspicious, Cosmo," answered his wife annoyed. "I request help." Harry took a glance at the letter. Wanda wrote it from his point of view, she even emulated his writing. In a way, it was impressive. She wrote as if he was unaware of magic. Which is realistic and would be the case if he hadn't these two by his side.
"What do you mean by vault key? Also the letter states to reply by owl?"
"Owls are the magical mail solution. You see, their banks use vaults that need key's. Your parents should have left behind a few vaults worth of gold for you," explained Wanda. "Cosmo, would you mind turning into an owl and deliver the reply to Hogwarts?"
"Seriously, flying all the way to Scotland?"
"No you idiot! Just turn into an owl before you reach the castle!" Wanda replied annoyed with Cosmo's stupidity. "Teleport, of course."
"Yes ma'am!" With that, he poof'd away with the letter.
Not a day later, someone knocked on the door. According to his aunt's reaction, it had to be some one magical. Cosmo and Wanda turned into their typical form of pins as they heard a woman ask, "Where is your nephew, Mrs Dursley?"
Harry pretended to try open the door of his cupboard and said, "I'm in here!"
He heard her say, "Alohomora," and the door opened. There he saw a strict looking witch in an emerald green robe. She turned to Petunia, "In the cupboard? In the cupboard, Dursley! No wonder the boy believed our letter in a heartbeat."
Harry heard Wanda whisper, "I like her."
The witch pulled Harry out of the cupboard and told him, "My name is Professor Minerva McGonagall, I am the deputy headmistress of Hogwarts and teacher for Transfiguration and here to answer your questions about Hogwarts and our world. And I will take you to get your school materials."
"We don't allow the boy to attend your school for freaks!" yelled Vernon Dursley.
"Your opinion doesn't matter, all magical children are required by law to receive magical education. Either you comply, allow teachers to conduct schooling in your home or I inform the ministry and the parts of your muggle government we are in contact with. These are all your three options. Nothing more."
"We don't allow your people here! Leave my house!" yelled Vernon.
His wife interfered, "Vernon! Let him attend, he will be out of our hair for most of the year, then." She turned to the professor. "Right?"
"He will only be required to stay here for the summer as the summer breaks are the only breaks that the students can't spend at school," clarified Professor McGonagall. "But seeing as you kept him in a cupboard, that may change as well. I will leave and inform the ministry of you, as well as your government. I will return in a week to take the boy shopping for Hogwarts as you can't be bothered."
After Professor McGonagall left, Harry was moved to Dudley's second room. Well, it was more a storage room. It wasn't even used as a guest room when Dudley's friends slept over. After the week, she returned. Outside the house, she said, "What we do now is Apparition. Side-by-side apparition to be specific. This is one method of transportation in our world. You can learn it and do your licence starting your sixth year at Hogwarts, the exam for the license when you are seventeen." With a blink, they were somewhere else. He felt as if a hook pulled him at his naval. When the feeling diminished, he realized they were in London.
Professor McGonagall guided him to a pub. The clothes of the clientele told him that this was a pub not meant for normal people, of muggles, according to the Professor. There they met one of his future teachers, Professor Quirrel, the teacher for Defence against the Dark Arts. His stuttering made Harry doubt that man could defend anything.
Then they walked into the Diagon Alley. The most chaotic and magical place Harry ever saw. Until now. Their first stop was the bank where they met Rubeus Hagrid. Not a teacher but still one of the professor's colleagues. He was there to pick something up for the headmaster. After Harry saw the most gold he had ever seen – and got a run down on the currency of Magical Britain – they started to check off the list. Starting with the robes, as there would take the longest to be made. They pick them up when they're finished.
While Madame Malkins took his measurements, Harry had the displeasure to meet a soon to be schoolmate of his...
All in all, Draco Malfoy sounded like a thin Dudley.
"And who are you?" asked Draco.
"Harry Potter," answered Harry.
"Potter, you say?"
After Madame Malkins was done, Professor McGonagall and guided him to their next stop. After they were done, she asked, "Would you like to get a pet? Maybe an owl for mail?"
"I doubt the Dursley's allow one. Or anything coming from here," he said, "It is more likely they allow a cat from an alleyway or shelter." He then asked, "Do I need to return to the Dursley's?"
"Sadly yes, but only for two weeks at least for... legal reasons," she said. "Now, as the Dursley's are lack-lustre to say the least, I got my colleague Hagrid to pick you up for Hogwarts. He will bring you to the train and then floo to Hogwarts."
"Floo?"
"Another transportation system."
After she explained the floo network to him over a little ice at Fortescue's, she returned him to the Dursley's. There he had an idea, "Cosmo, Wanda, who of you would like to pretend to be an owl?"
"I would prefer to be a cat," was Cosmo's answer. "That would roll better with the alley cat thing you told her."
"That is a good idea, Cosmo!" agreed Harry. "You will be a cat, then."
"Will you call his cat form by a nickname?" asked Wanda.
"No. Just Cosmo."
Soon Hagrid came and brought Harry and his cat Cosmo to King's Cross. When he left, Wanda showed him the way to the train. It was hidden between two muggle trains. The train itself was red which made him wonder if the headmaster has a preference for the Gryffindor house. Cosmo and Wanda didn't think the following year will be the most stressful time they ever had with Harry.
Partly because they distracted themselves with a worry as they saw how Harry reacted to the school.
"Wanda, could it be that Harry doesn't need us any more?" asked Cosmo as they watched his Transfiguration class bewitching pin cushions and needles.
"Have you read the changed Da Rules? Due to the prophecy, we won't leave until he defeats Voldemort," she reminded him.
"Oh, right. I forgot."
"You seriously forgot Jorgen yelling at you?"
