Undone

All recognizable characters belong to J. K. Rowling, and I am not earning anything by writing this story.
I am not a native speaker of English. Please excuse my mistakes.

COMPLETELY AU! Partly OOC.

It is my story, and I intend to write it the way I want it. If you don't like it, don't read it.
Reviews are very welcome, as they inspire my muse. Thank you very much for the kind feedback on the previous chapter!

"I love you, Luna," Harry said, urgently, inwardly panicking.

"Oh Harry, I love you, too," Luna replied, light blue eyes locking into emerald green. "I want to marry you, of course, I'm just not sure if it would be wise to marry next year. Perhaps we should wait until after the NEWTs," she added, giving Harry a dreamy look that made him sigh in relief.

"Thank Merlin," he blurted out. "Of course, if Tom manages to annul that stupid marriage decree, we can wait until we finish Hogwarts. As long as you're going to be my wife, I don't mind when it'll be."

A week later, Tom and his allies visited the now completed ministry building to make sure that everything was ready for the grand opening on the first of July.

"Tom, don't forget to instruct the ministry elves to pack all the offices and move everything here in the morning of the first of July," Amelia reminded him.

Tom nodded. "Yes, I know, and I already told them about it right after the bonding ceremony the other day," he explained to the older witch, who had turned out to become his most valuable alley. "Thank you for everything, Amelia," he added, smiling.

"You're welcome, and I thank you, too," the head of the Department of Magical Law Enforcement replied, returning the smile.

HP

Very early on the first of July, Amelia organised the evacuation of the old Ministry of Magic and made everyone apart from some bigoted purebloods travel to Stonehenge, either by Apparition or through the fireplace, knowing that the new fireplace was already connected to the Floo network.

"Stonehenge is the name of the fireplace?" one of the employees asked her in apparent surprise, causing Amelia to nod.

'I thought all heads of the departments had told their employees everything,' she thought in annoyance, wondering when the few remaining bigots would realise that something was off, especially since most of the offices would be completely empty after one hour at the most.

After informing everyone, Amelia took a last glance at her old office, making sure that the elves had taken everything to the new Ministry of Magic. Finally, she left the building to apparate to Stonehenge with the intention of making sure that everyone had found at least the main entrance.

Thankfully, the whole area was warded widely, so that the muggle tourists would notice nothing about the commotion that was going to occur with the new ministry building just below.

HP

Tom was standing in his new office, accompanied by Harry as well as Angelina and Alicia, who were his new undersecretaries.

"Shouldn't you go and see that everything is all right?" Harry asked his best friend, who gave him a surprised look.

"I'd rather think I should wait here. If anyone will have any problems, they're surely going to come here," Tom replied, giving Alicia and Angelina a questioning look.

"I think so," Alicia replied, nodding.

"Maybe Alicia and I should go and check on everyone," Angelina offered, grinning.

"Yes please," Tom immediately agreed.

"Thank Merlin that you got those two as assistants," Harry said, once the girls had left the room. "They're absolutely trustworthy, and you know them well."

"Yes, that's true," Tom confirmed. "I'm really happy to have them here."

HP

At ten o'clock, Amelia entered the minister's office and informed Tom that the relocation of the ministry was complete.

"Very well, shall we gather everyone in the large hall for a short welcome greeting?" Tom suggested and, seeing Amelia agree, used a Sonorus charm to invite all employees of the new ministry to the large assembly hall.

"Tom, shouldn't I return to Hogwarts?" Harry asked, feeling slightly uncomfortable. "I'm not an employee here."

"But as the minister's best friend, you have all the right of being here," Tom replied, pulling Harry with him through the modern looking corridors.

HP

"Good morning and welcome to our new, modern Ministry of Magic," Tom greeted the assembled employees. "I hope that you're all going to be very happy working here, and if you have any suggestions as to how to improve our work for Britain's magical world, feel free to come straight to me and inform me. Furthermore, I'd like to ask all heads of the departments to show the members of your department the shortcuts, which Madam Bones has assigned you last week. Don't worry, the muggles won't notice you, not matter from which stone you leave or access our building. Now have a good time, and I'll see you all soon." With that, Tom ended the welcoming greeting, and everyone returned to their offices.

"That was short and precise," Amelia said, smiling in apparent appreciation.

"Thank you Amelia," Tom replied and led Harry back into his office.

Alicia and Angelina shared the office right before Tom's, and the minister's fireplace was situated in their office to allow the minister a little privacy. The four of them had just returned to the offices, when the young witches' husbands stuck their heads into the fireplace.

"Tom and Harry, just so you know…"

"… hearing that everything here is complete…"

"… we just went and made a couple of Scorgibombs explode in the old ministry…"

"… to destroy everything and banish all evidence," the twins informed them.

Harry cast them a horrified look. "Did you make sure that there weren't any people in the building before destroying it?"

"Err…"

"… No…"

"… We remotely made them explode…"

"… We'd already asked an elf to place them throughout the ministry…"

"… a couple of days ago," the twins admitted.

Harry stared at the fireplace in shock. "Tom, we still have a few phials of the time reversal potion left. I'll go and get one, and I'll head to the ministry and warn everyone that the building is going to be destroyed after thirty minutes," he finally spoke up in a firm voice. "May I use your fireplace to floo to the headmaster's office please?"

"Harry, I instructed the twins to do so. But please go and warn anyone who might still be there," Tom agreed, smirking.

Harry hurriedly stepped into the fireplace, hoping that he could save some innocent lives – if there were any left at all in the old ministry building.

HP

Dolores Umbridge was sitting on the floor of her small ministry holding cell, grieving and racking her brain how to possibly get away from her cell, last not least to take revenge on her former husband.

"Cornelius, any idea?" she asked the former minister, who occupied the cell next to her.

"No Dolores, how would I? Everything is your fault anyway. If you hadn't kept him under the Permanent Imperius, that meeting wouldn't have occurred in the first place.

"Exactly," Bellatrix spoke up from her other side. "You stupid bitch."

"Ahh, shut up you two. You better…"

None of them was going to hear what Lucius Malfoy had to say, as a loud announcement sounded through the ministry.

"Dear former employees of the Ministry of Magic, the new ministry has opened its doors this morning and this old building will be abandoned and completely destroyed in exactly twenty-five minutes from now on. Please remove yourselves from the building as long as you can and have a good day."

With that the announcement ended, and Dolores let out a cry of horror.

"And what is with us? You can't just leave us here!" she shouted, horrified.

"That was Harry Potter's voice," Lucius spoke up, sounding bored.

"How dare they leave us here?" Dolores shouted in disbelief.

"How did you dare do what you did to Tom?" an icy cold voice suddenly spoke up.

"Potter!" Lucius shouted. "Take us out of here."

"I will," Potter replied and did the unthinkable. He transformed into a fire phoenix. He flashed into one of the cells, and Dolores could hear him say, "Lucius, grab my tail feathers." An instant later, he added, "Beatrix, hold on. Good bye Fudge and Umbridge."

With that he flashed away in a bright flash of fire.

"And we?" Dolores shouted, horrified, just when she heard a couple of small explosions that obviously began at the other side of the building but quickly came nearer, before everything turned black.

HP

Harry flashed his two guests right into the new ministry, where he knew the holding cells to be. Leaving them both together in one cell, he immediately went to alert the Aurors, who then took the Death Eaters straight to Azkaban.

'Apparently, Tom wanted them to have the same fate as Umbridge and Fudge,' he thought, when he returned to the minister's office. 'But I still don't think they deserved it, even if I don't know if Azkaban will be so much better.'

He quickly informed Tom about the matter, before he took his leave and returned to Hogwarts, knowing that Luna was impatiently waiting for him.

HP

Harry's sixth and seventh year passed uneventfully and even a little boring in comparison to earlier years. Since there were no Sunday evening meetings anymore, he had more time to spend with Luna, and the two of them often joined Hermione and Tom, who were now living in the founders' quarters, occupying one of the old and comfortable bedrooms.

"I wished we could just live in the founders' quarters, too," Luna said one evening, when they made their way back to Wallace house. "I mean, I like Wallace house too, but I miss the older students who have already graduated."

"I know what you mean," Harry said in understanding.

"I especially miss Tom and Hermione, but also the twins and their wives, Cedric, Oliver… I know the younger students are also nice, but it's not the same," Luna said, sounding a little sad.

"We can move to the founders' quarters if you wish," Harry suggested, causing Luna to give him a dreamy look.

HP

After frequent discussions about the same matter, Harry and Luna finally decided to move to the founders' quarters after their sixth Hogwarts year. They still spent some time in the common room, and sometimes, their remaining six classmates who were still residing in Wallace visited them in their new rooms.

It was a few weeks before the NEWTs that Harry and Luna were more or less accidentally cuddling on the most comfortable sofa in the spy room, when they witnessed an interesting conversation taking place in the headmaster's office.

Apparently, the headmaster was together with the five heads of the houses, but Harry was not exactly sure, since they could only hear but not see anything.

"Albus, I wonder if it might be wise for you to retire in favour of Harry after this school year," McGonagall spoke up seemingly out of the blue. "He's the owner and as such surely has the best interests for Hogwarts in mind, and it might be good to corner him before he leaves for some position at the Ministry of Magic, considering that it's run by his best friend."

"I agree," Rosie voiced her opinion.

"Yes, Harry would make a good headmaster," her husband added.

Sprout and Flitwick shared the other heads' opinion, and finally, the headmaster gave in.

"Maybe you're right, although I'm not really ready to leave Hogwarts after spending more than a century here," Dumbledore said in a small voice.

"Maybe Harry will think of something to still occupy you here," McGonagall replied in a soft voice. "You could always remain as his deputy."

"Would you not mind?" the headmaster asked, incredulously.

"Not at all, Albus. Not at all. It was not my intention to get rid of you," the Gryffindor head confirmed.

HP

"I know what I'm going to do," Harry spoke up. "Let's go and speak with Hogwarts."

Together, the two seventh years headed into the Parlour, where Harry addressed the castle.

"Hogwarts, I'd like to re-build the Shrieking Shack to a home for retired teachers," he spoke up. "Would that be possible?"

"Of course my dear," Hogwarts replied, gently. "I think that this a very noble and wonderful idea."

HP

It was only after the last NEWT exam that the headmaster called Harry into his office and offered for him to become his successor as headmaster.

"I'll happily accept," Harry replied, feigning surprise, and also agreed when Dumbledore suggested to become his deputy.

"Frankly speaking, I believe that I'd like to keep some of my classmates here at the school," Harry replied, thoughtfully. "For example, I'd like Daphne Greengrass to become my deputy headmistress. However," he added, "I'd like to offer you the position of the professor for the new subject of Alchemy."

"I accept," Dumbledore replied, quickly.

"During the last few weeks, I've made a few changes around Hogwarts," Harry announced and explained that the former Shrieking Shack was now a home for retired teachers – much to Dumbledore's pleasure.

"I will also create several more new positions," Harry continued, causing Dumbledore to cast him a surprised look.

HP

As soon as the students had boarded the Hogwarts Express to return home, Severus Snape visited the new headmaster in his office, holding out a potion to his former student.

When Harry gave the Potions Master a questioning look, he smirked. "Can't you imagine what it is?" he queried, quirking an eyebrow in clear amusement. "I didn't want you to take the cure before the end of the school year, considering that Weasley had to serve detention with Filch until your complete healing from the Influenza Magica."

"A cure?" Harry asked, wide-eyed, smiling broadly upon seeing his colleague's contented expression. He gulped down the slightly yellow liquid without lingering on the taste.

"Severus, I can't thank you enough. You've no idea what this means to me," he then uttered, fighting back the tears that were welling in his eyes."

"You're very welcome," Severus replied. "I'm glad that I could help. I haven't forgotten what you've done for my daughter."

Harry smiled, knowing that Gwendolyn was very happy with her soon-to-be husband.

"Are you really going to do a common wedding together with all of your classmates?" the Slytherin enquired, causing Harry to grin.

"Yes sir. Five weddings on the first of August? You have to admit that it's economic in every way," he replied, absentmindedly petting Itsy, who was sitting on his lap.

HP

Harry decided to add one apprentice to each of the main subjects. While Gwendolyn became the apprentice to her father, Neville became Professor Sprout's apprentice, Justin was selected to assist Professor McGonagall and Susan Professor Flitwick. Knowing that the heads of the houses mostly were too busy with their own classes to properly look after the students in their house, he decided to invent two new positions of student advisors. Luna and Hermione had already shown interest for the positions, and Luna became the student advisor for personal matters, while Hermione took over the position of the student advisor for academic topics.

At the same time, Harry abolished the Divination class, knowing from his soon-to-be wife that either one was born a Seer or one would never be one. As compensation, he offered Sybill Trelawney a room in the home for retired teachers, which the former professor gratefully accepted. "Everything is better than the option of having to marry Ronald Weasley," she told Harry, confidentially, when he introduced her to her new room.

"I understand all too well. Thank Merlin Tom managed to undo all of these idiotic rules," Harry agreed, smiling.

The rooms in the newly renovated building were similar to the teaching quarters at Hogwarts, and the members of the new home were also offered to take their meals in the Great Hall at Hogwarts, which was easily accessible through a shortcut door leading from one entrance hall to the other.

Although Harry as the headmaster was not required to teach classes, he took it upon himself to teach just one class, the Animagus class. It was an elective subject for all students from second year onwards and took place on Sunday afternoons.

HP

Just a year later, Harry realised that he soon would have to add another new building to Hogwarts. Since all of their classmates married on the first of August after their seventh Hogwarts year, during the following year, all of the younger teachers and assistants became parents.

"We need someone to look after the children," he said, pensively, watching Luna breast feed their baby girl Lily.

"Maybe you could build a school building for young children, from four years onwards or such," Hermione spoke up, while feeding her own newborn, James.

"I suggest Ginny Weasley as teacher for the kindergarten class from maybe two years onwards," Luna added, as she handed the baby to Harry to make her burp.

"I'll speak with her in the morning," Harry replied, pensively. "Maybe for the time being we could just re-build some unused classrooms. There are enough to hold about ten different primary school classes plus a kindergarten class or even a nursery."

HP

During the following years, the Hogwarts Primary School became a fixed part of the Hogwarts educational system that expanded, as the children of the first Wallace class grew up together like siblings.

"Thank Merlin they don't have to think about whom they want to get betrothed to before even becoming a student here," Susan said to Harry, when they were sitting at the head table waiting for Daphne to lead the new first years, respectively their own first-born children, into the Great Hall for the Sorting.

"Yes, Tom really deserves the Order of Merlin first class again for saving us all from a disaster. Thank Merlin that he has UNDONE the idiocy of the old ministry," Harry agreed, smiling.

The End

Thank you very much for your kind reviews throughout this story!
