[HP] Butterfly Effect

Early in the morning, the Hufflepuff common room was bustling with activity.Standing at the outermost edge of the crowd, Aurora could fully guess what they were discussing excitedly, because she was the one who nailed the notice last night.

The black English words are entangled and stretched on the parchment printed with the photosensitive badger logo, which is as gorgeous and beautiful as vines. It says:

"Apparition class,

If you're 17 or over on 31 August, you can take a twelve-week Apparition course run by a Ministry of Magic Apparition teacher.

Those who wish to participate please sign below.

Tuition fee: twelve Galleons. "

Bradley was already sitting at the table under the notice, processing the students' signatures, and the curious and excited little badgers surrounded him, chirping and asking questions, all wanting to sign on that piece of paper to learn .Others are sitting on the sofa anxiously, frowning and seriously calculating how much money they have left to spend on this course.The students who really couldn't afford enough tuition fees turned around and went back to their dormitories, preparing to sell some beloved gadgets to make up for tuition fees.

"It seems that everyone wants to learn this spell." Aurora looked at the team in front of her, and there were probably seven or eight people who could sign her name.Tonks, who was just here to join in the fun because he was not old enough, nodded in agreement: "Who says no? After all, it's so interesting to be able to disappear in one place and reappear in another at any time. It's a pity that this class has an age limit." Limit, otherwise I want to sign up too. When will you take the exam?"

"You can do it when you are 17 years old." Aurora recalled the details she knew when she posted the notice yesterday, and replied, "Because we will be adults at that time, and we can use magic outside of school." "That will be very fast for you." Already!" Tonks said cheerfully, "You will be 17 in a few months. Have you thought about how to spend your coming-of-age ceremony? I heard that a group of Gryffindor students plan to go to Hogg Maude has a drink or something. Bar mitzvah, you have to do something you've never been allowed to do before."

Aurora shook her head, looking a little helpless: "I haven't thought about it yet. Let's talk about it after I make up my homework during the recent period."

When she was determined to regain her energy from the ghostly prediction of fate trajectory, Aurora didn't realize that she had left behind so much content until she went back and carefully sorted out her study notes during this period. I found that I had really been depressed for a long time.

The most bleak is Professor McGonagall's Transfiguration class.Although Aurora has always been one of the best students in the Transfiguration class, Professor McGonagall still looked fairly at the few papers she handed in some time ago when she was still in a daze, and the scores were predictably low. .If she wanted to keep her Transfiguration class points this school year, then Aurora would have to work extra hard in the later stages.

Then there was the astronomy class. Aurora found that she couldn't keep up after a few lessons a while ago.The stars in the sky swirled rhythmically in Cynthia's hands, but unfortunately all of them fell into Aurora's eyes in the end, turning into a burst of dizziness and confusion.Fortunately, Cynthia was finally relieved to see her gradually returning to normal, and enthusiastically proposed that she could spare time alone to tutor her.

"It's great that you can be happy again." Cynthia sighed while skillfully drawing the trajectory of the starry sky on the blackboard, her light brown curly hair was gently tied into a ponytail hanging behind her, "You don't know my How worried I was with Sirius some time ago. Every time I wanted to talk to you, I was caught up in various things, so I had to let him come alone. The students always have endless questions to ask, and I also have endless papers to correct. And the star chart. Sometimes I think, if only I hadn’t attended the school celebration that day, you wouldn’t have been so affected.”

"It's my own problem, professor, don't worry, I've figured it out now." Aurora scratched the tip of her nose with a quill, watching the starry sky maps spread like spring flowers under Cynthia's hands, fascinated brilliantly complex.

Cynthia shook her wand and said with a smile: "That's good. In fact, you don't have to pay too much attention to the trajectory of fate. The reason why I chose it to make predictions at the school celebration is because everyone's fate trajectory is different. Changed. Current forecasts are not indicative of the true future."

"I understand now." Aurora nodded.

After leaving from Cynthia, Aurora came to the Defense Against the Dark Arts classroom full of quarrels to find Sirius and hand in the class papers that she forgot to write last time, although Sirius seemed more willing that Aurora just kept forgetting about it .He wasn't at all interested in reading students' papers, and if it weren't for the Hogwarts rule that coursework must be written, he wouldn't even bother himself with giving students papers.

Compared with theory, Sirius puts more emphasis on practical operations. He always has his own method to make every student familiar with the newly learned spells as quickly as possible, and use them with ease.The same spell in his hand can show many different effects after some subtle controls.Therefore, the proportion of the paper's score was suppressed by him to the bottom line that Dumbledore could accept. If he got busy occasionally, the score for the paper was quite random and depended on his mood.

Of course, no matter what mood he was in, the Slytherins rarely got good from him.

When Aurora handed over the paper, Sirius twitched the corner of his mouth: "I thought you didn't hand it in to help me reduce my workload. It seems that I was wrong."

"I did think about it." Aurora responded teasingly, "But after thinking about it, I still have to go to higher education, and I think it's better to forget it." Sirius laughed shortly, and leaned back in the chair relaxedly, Eyes squinted to look at her, wand twisted between fingers: "You seem to be well adjusted."

"You have to look ahead, no one knows what the future will look like." Aurora said with a gentle smile. "It's best if you can figure it out, and Cynthia should be relieved." Sirius tapped his fingers on the table a few times before suddenly asking, "How are your eyes now?"

"It's okay, that's it." Aurora replied.Sirius tilted his head and clicked his tongue, knocking the wand in his hand on the table, his brows were furrowed, and sharp dark gray waves were in his eyes, almost overflowing his perfectly lined eye sockets.

"But don't worry, at least it's a good sign if it doesn't get worse."

After hearing her words, Sirius glanced at her: "You are probably the only one in the world who still thinks this way when you encounter such a thing. Sometimes I really don't understand what you are thinking."

"I have to go to the History of Magic class in a while, so I'll be leaving first."

"Go."

As one of the compulsory courses at Hogwarts, History of Magic is probably the most boring of all courses.But Aurora is very grateful for this kind of boredom, because it means that she can keep up with the progress of the course even if she was out of state some time ago-it is mainly self-study anyway.

After entering the sixth grade, the teaching content of the history of magic was transferred from the British mainland to the world.Aurora opened the book and glanced, and found that Beauxbatons and Durmstrang had been introduced in the previous class, and the content of this class was Ilvermorny in North America.

She took out her notebook and began to sort out what she had left behind.Not long after, other students came in one after another, and most of them looked exhausted, bringing in thick books as pillows to catch up on sleep.Professor Binns also floated in from the window after the students had basically arrived, and he muttered slowly in his iconic low hoarse voice: "Today we will talk about Ilvermorny in North America. And our Hogwarts It is also a college specially established for young wizards, just like Liz."

"Ilvermorny was founded in the 17th century and sits on top of Mount Greylock. It is sometimes seen as if it is surrounded by a mist due to the fact that it is concealed by various powerful magics to keep non-magical people from seeing it."

"Also like Hogwarts, Ilvermorny also has four colleges, and each college is represented by an animal house emblem. They are Thunderbird, Goblin, Cat Leopard, and Water Snake."

"Isn't this similar to our school?" A student whispered at the bottom.Bill flipped through the pages and said, half-jokingly, "It's true. Thunderbirds versus copper eagles, cats and leopards versus lions, goblins versus badgers, water snakes versus silver snakes."

Professor Binns didn't seem to hear the students' discussion, and continued to read the contents of the book dryly: "Like our school, Ilvermorny also has a special sorting ceremony for new students. The qualities are different. The sorting ceremony determines where the students go for the next seven years."

"So, Professor." A Gryffindor girl in the front row suddenly raised her hand and asked curiously, "Does Ilvermorny have a sorting hat?"

Professor Binns, who was rarely asked so sincerely by students about the teaching content, looked panicked, as if he was also surprised that someone was listening to his class, he stuttered when answering, and even his spirit body began to become Blurring: "Uh... Ilvermorny doesn't have a sorting hat. They are students who stand on it and are chosen by the four magical creature totems representing the house. Of course... sometimes several houses will choose a student at the same time But that's rarely...well, unless it's exceptional. I remember Serafina Piccolo as well. Back then..."

"You just said to stand up, professor." The girl continued to ask with difficulty in understanding, "I don't quite understand, where did they stand to sort the school? And why did you talk about so many schools? Ilvermorny seems to be It seems so similar to our Hogwarts?"

"Uh, well..." Professor Binns muttered, feeling that the other party asked too many questions at once, and each of them could explain a lot, and he needed to organize his words before he could answer.

The classroom was discussing the fact that some students from Ilvermorny might be selected by more than two colleges at the same time, which was really new to them.

"What if it is really selected by several colleges at the same time?" Another Hufflepuff also asked enthusiastically.It seems that everyone started to find this course quite interesting at this time.

"Then...if that's the case, it's up to the students to choose which college they want to go to." Professor Binns replied softly, feeling a little overwhelmed by the suddenly lively classroom atmosphere, rubbing his hands unconsciously, " As for the location of the branch, yes, it is in a circular basement, a..."

"It's in the rotunda, where the Gordian Knot is engraved on the ground." Aurora corrected without raising her head.Everyone else turned to look at her in unison after hearing this, especially Bill and Vaux, with extremely surprised expressions.

After realizing that everyone around her was looking at her, Aurora also froze, and realized that she should not have interrupted the professor so abruptly.She didn't even realize what she just said, but after hearing Professor Binns' slip of the tongue due to nervousness, she felt something was wrong almost instinctively.

"I'm sorry, Professor." Aurora quickly stood up and apologized.

"No, no need to apologize, just sit down." Professor Binns stared at her in bewilderment. "In fact, you are right. It is indeed in the rotunda, where the Gordian Knot is engraved on the ground."

"How do you know? Have you been to Ilvermorny?" Bill asked curiously.Aurora shook her head, "No, isn't it in the book?"

Vox flipped through the pages, glanced at a certain place, and pointed out: "Ah, here. Each student is selected by four magic statues to determine whether they are eligible to enter this academy."

"That's right, I just said I saw it somewhere just now." Aurora said prevarication.Bill followed suit and started flipping through the book carefully, not feeling that there was anything wrong with Aurora's explanation.

However, only Aurora knew that she had never read the book, nor did she deliberately and meticulously understand Ilvermorny.But her reaction just now was so familiar, as if she had been there many times before, this uncontrollable phenomenon cast a shadow on Aurora's mood that had just calmed down recently.

After class, she went to the History of Magic section of the library and found several books that introduced Ilvermorny in detail and systematically.Turning over a page of the brown leather-bound tome in front of her, Aurora's eyes first fell on the illustration.For a moment, she felt that the blood in her whole body was frozen, and all the voices in her ears were pulled into smooth and rigid white noise, and the whole world was cut off from her.

The pattern depicts a part of the inner landscape of Ilvermorny, and the technique is so simple that it is somewhat abstract.The sunlight was visualized into a few straight lines shining in from the window, portraits with different expressions greeted the hurrying students on the wall, magnificent crystal lamps were hung on the vaulted dome of the castle, surrounded by The shapes of the two auxiliary lamps respectively symbolize the images of magical creatures of the four colleges of Ilvermorny.

This painting, when Aurora saw it at first glance, believed that it depicted a scene that often appeared in her dreams. She was very familiar with it and had painted it many times, so she would never admit it wrong.

Have you ever been to Ilvermorny?Aurora stared at the painting, her thinking slowed to a standstill.She tried her best to restrain the feeling of anxiety and depression that was about to resurface, and warned herself not to be overly influenced. Since she had decided to look forward no matter what, she couldn't let the same thing cause her to slump again.

The future can be changed at any time, Snape said, Cynthia said, Dumbledore also said.Belief too obsessively in the prophecy will only be disturbed by the prophecy to the point where you lose the judgment you should have, and will unconsciously confirm it.

Aurora took off her glasses, wiped her face with slightly sweaty hands, the temperature was cold.She closed the book, stared at the eye-like lines on the wooden table, and repeatedly reminded herself not to be controlled by fear again.

After a while, she put on her glasses and opened the book again, and saw the history of Ilvermorny's creation.It was established by a married couple, wife Aesop Searle, a wizard, and husband James Stewart, a Muggle.

Later, when Aesop Searle chose the emblem of one of the colleges, he chose the long-horned water snake. It is said that it was because a very spiritual long-horned water snake once gave her a lot of help.

Aurora was slightly stunned when she saw this, something subtly cracked in her mind.

Horned Hydra, Help, Founder of Ilvermorny.

Merlin, how could she forget this? !

Driven by the almost crazy guess in her mind, Aurora quickly rushed out of the library and went straight to the basement with the book in her arms.The Bowtruckle Tea Roll, who had been sleeping peacefully in her hood, was frightened by the sudden accelerated run, her thin little paws were tightly grasping the brim of the hat, shivering behind those fluttering light-blond hair.

She knocked on the door of Snape's office, and spread out the books in her arms in front of him.Before he could worry about the not-so-friendly questioning eyes of the other party, Aurora pulled out the quill in Snape's hand and a piece of blank parchment next to him, and used the fastest speed to draw the Ilvermorny-like figure in his dream. After drawing the scene, he handed it to Snape, his eyes were firmer and brighter than before: "This is Ilvermorny, Professor, the place that appeared in my dream. When I was in History of Magic class, Bin Professor Si accidentally made a mistake about a detail about Ilvermorny, and I realized it right away, but I didn't even pay attention to it before that. Until I saw this picture."

She put her finger on the illustration in the book: "They're exactly the same, Professor!"

After listening to her, Snape quickly compared the two pictures, just like Aurora said, they were very similar.

"And here." Aurora said, turning the page forward, "The founder of Ilvermorny, I almost forgot this! It is said that when she first arrived in the United States, she got a lot of help from a long-horned water snake. So when choosing the college emblem, she chose a water snake. But..."

"The horned water snake is a magical creature, and non-Parseltongues cannot be controlled." Snape continued, looking up at her, "You mean to say that she is a Parseltongue, a descendant of Slytherin."

"That's right." Aurora looked at him and nodded, because of the sprint just now, she replied with some breathlessness, "I also think that since she is also a descendant of Slytherin, then it is possible for her to get Slytherin Mister Wand Man."

Snape's eyes flickered and became a little gloomy.Aurora's words reminded him of the locket, which the Dark Lord had also collected elsewhere.In other words, it is absolutely possible that some of the treasures of the Slytherin family accidentally escaped during this 1000-year period.And according to Aesop Searle's own statement in this book, she is indeed not from the United States, but she did not say where she is from.The records she left behind are very limited, most of which are related to Ilvermorny, but very little of her own experience.

Therefore, Aurora's guess is reasonable to some extent.

Thinking of this, Snape took a look at the painting again, and asked: "Have you ever actually dreamed about the scene related to the wand?" Aurora collected her thoughts and shook her head: "Not really, But Ilvermorny has been many times. I always feel... as if I've been there before."

Seeing that the other party was distracted by recalling the dream, Snape frowned.He took out a drawing that Dumbledore gave him two days ago, and brought it in front of Aurora: "You drew this?"

After taking a look, Aurora nodded in confusion: "Yes." "It looks like you haven't finished drawing it yet." Snape turned the paper over, and the light sunlight shone on his hands through the glass window, deepening the twisted darkness of those patterns, "What are these?"

"A magic wand, a ring, and a piece of clothing that looks like a cloak." Aurora replied, asking with some puzzlement, "Is there any problem with this, Professor?"

"It's nothing, you go back first." Snape said without changing his tone, turning the piece of paper over and putting it aside, "As for the things you said about Ilvermorny, I will tell the headmaster .”

"Okay. Then I will trouble you, Professor." After finishing speaking, Aurora planned to go out.However, within a few steps, Snape suddenly stopped her again: "Wait."

"Eh?" Aurora turned her head, her slightly long and thin bangs gently stroked above her eyebrows, leaving a light shadow in her clear eyes, "What's wrong?"

Snape tapped his finger on the table, his eyes were as cold and deep as his voice: "My pen." Only now did Aurora realize that she was still holding Snape's quill in her hand, she was so excited when she rushed in So much so that she didn't even realize that she snatched the pen directly from his hand.

"Oh... I'm sorry, I'm sorry, Professor." Aurora pursed her lips in embarrassment, walked up to hand the quill back to the other party, and left the office.

The quill twirled half a circle between Snape's fingers, ready to continue falling on the paper to outline words.But Snape looked at the parchment which he had turned upside down for a while, his eyes fluttering with dark coldness.

He put down his pen, folded the painting and put it in his pocket, went to the kitchen to find Aidara, and asked her to take him to the secret room.

Compared with Slytherin's common room, both the light and color and the furnishings here are much sharper and colder.Green shadows are everywhere, clinging to and growing on the black walls and floors like lush water plants, blurring people's judgment, making people unsure of the reality of the ground under their feet, as if surrounded by endless dark tides, just standing there is frightening .

The huge basilisk Abyss is obediently entrenched in the center of the secret room, sticking out its slender tongue from time to time to lick the water in the pool.After noticing the arrival of Aidara and Snape, it just turned its head and glanced at them with golden eyes, and did not make any other movements, as if it didn't see them at all.

Salazar lay motionless on Abyss's scaly back with his eyes closed, his silk-like robes hung down, and his whole body looked like a delicate wax figure: "If you have anything to say, just say it." .”

"I'm sorry to disturb you." Snape bowed slightly and said, "I came here to ask you about the Deathly Hallows."

After hearing this word, Salazar finally sat up, with his arms on his knees, and his eyes under the half-raised eyelashes were dark green, like those weird and weird Mirkwoods in porn: "Why do you suddenly care about this? ?”

Snape took out the painting in his pocket, picked it up with his wand, and let it completely stretch out and float in the air: "This is a part of Field's painting, which often appears in her dreams. People from the Sidney family predicted it for her before. After reading the trajectory of fate, she accidentally discovered that her fate trajectory has been repeated, and she has a strange sense of familiarity with many things that are about to happen, but it is not a simple perception of prophecy. So I was thinking, this matter Is there any connection between them?"

After hearing Snape's words, Salazar's eyes fluctuated slightly for a moment, and the cold light gathered in his eyes, almost as sharp as condensation.He was thinking in silence, and suddenly whispered something in snake language, the tone was so soft that it made people tremble.Immediately afterwards, Salazar refocused his attention on Snape, saying: "I know what you are guessing, but I can't say I really know whether it is correct or not. Because the Deathly Hallows never appeared at the same time. Once it's done on one person, no one knows what it's going to do."

"But put these aside. I personally agree with you. Her reincarnation may really have something to do with the Deathly Hallows she dreamed about."

Then it seemed that Slytherin's wand was indeed in Ilvermorny, Snape thought.

"What about the wand?" Salazar asked again, interrupting Snape's thoughts.Snape replied: "There is a pretty clear direction. We still need to verify."

He nodded slightly, "Where is that tree?"

"It's been on a slow decline. Lady Melanie Hufflepuff guesses it'll last three or four years at most, or less."

This answer didn't seem to exceed Salazar's expectations. He tilted his head casually: "Got it. Is there anything else?"

"No more." Snape said goodbye quickly.

He returned to his office and owled a letter to Dumbledore, who was researching ancient trees and wands in the Hebrides, mentioning what Aurora had said about Ilvermorny.After writing, Snape's pen paused for a long time on the end of the last word.The thick black ink gradually smeared on the parchment, soaking through the texture of the paper, like a black velvet flower blooming on the skin.

In the end, he still didn't write down what he and Salazar had discussed about the Deathly Hallows and Aurora's destiny.

The owl quickly disappeared into the sky with the letter, and Snape took out the painting again, carefully spread it out in front of him, staring at those strange symbols with cold and remote eyes.In his mind, he sorted out and connected all the recent events, and found that the symbol of the Deathly Hallows was indeed the key.

Repeated lines of fate, strange familiarity.Aurora seems to have experienced these things countless times, and this sense of fate has always existed in her subconscious, but now it is becoming more and more clear.

Why now?Why does it keep reincarnating like this?

The Deathly Hallows is a legend related to the god of death, and no one knows what effect they will have when they come together.But there is no doubt that they are always associated with death.Grim Reaper...Ghost Shark...

Snape took down from the bookshelf a book about ancient mysterious magical creatures and mysterious potion materials that he had borrowed from the library before, and saw that it was clearly written that since ancient times, ghost sharks have always been regarded as Is the messenger of death.And a long time ago, the ghost shark was worshiped as a totem by some fanatical black wizards.The most famous of them is the ancient Greek black wizard Haierbo, the inventor of the Horcrux, the earliest known Parselmouth, and the first person to hatch the Basilisk.

Why is it all about death?

Snape's fingers unconsciously clasped the hard edges of the book, and the sharp ridges crushed the pale skin of his fingertips.

In the middle of the night, he had a dream.In the dream, he went back to nine years ago, when he was just a child.At that time, in order to gain the trust of the Dark Lord and become the most important one among the Death Eaters, he accepted the task assigned to him by the Dark Lord without hesitation.A mission to kill Edmund Field's only daughter.

Snape stood not far from Aurora, watching her sitting by the river in a daze, with a bunch of freesias he just bought in his hand.Under the mellow and yellowish afterglow of the setting sun, her hair was so thin that it was almost transparent.The turbulence of the river, the fir forest that was only a blurred outline against the light in the distance, and the light green mist that never dissipated in Plymouth were all entwined in her eyes.She raised her body to reach the layer of water that was sprinkled with light and broken rainbows, so dangerously that Snape thought for a moment that she was going to jump in.

Suddenly, Aurora looked back towards Snape, and greeted Snape with a confused look: "Hello, do you need to ask for directions?"

This is different from actual memory.Snape was silent, walked over and stood beside her: "What are you looking at?"

"River, forest, sunset, cloud shadow." Aurora replied briskly, "And you, sir." She asked, "What about you?"

Snape's eyes flicked across the pointed arc of the iron-blue forest, across the river bank, across the golden flowing water, and finally landed on a butterfly on the top of the reed.His tone was more ethereal than the fog hovering over the forest, as if just saying the word had exhausted all his strength:

"you."

The author has something to say:

Three shifts
