A merger of magic and technology when neither is strong enough on its own. A secret weapon of the Harry Potter world is sent to an alternate world to find a way to stop the 3rd dark lord, Peter Potter who just happened to be the grandson of Harry Potter.

"Should we go? Ginny's down there!" It was Harry's voice.
Ah, I must be having a vision of the altered future.
Alex could see everything clearly now. It was Ron and Harry standing over the open entrance to the chamber in Myrtle's bathroom.
Ron spoke, "You remember what Alex said, a Basilisk is down there!"
"Yeah, but she said I defeated it. We can't wait anymore Ginny is down there, dying!"
Ron hesitated.
Shit.
A look of horror dawned on Alex's face as she realized what her reveal caused. Before they didn't truly know about the basilisk. They had a clue from Hermione but what if Alex's involvement changed Hermione's curiosity and ability to find out the truth. The Harry Potter story plot is fragile and based on a series of delicate accidents. Alex may have revealed the ending but the courage to fight along the journey slacked because they knew how it would end. They found out that everything turned out fine and they were heroes. They must have figured that the ending was set in stone so they put no real effort into their search.
Ron looked guilty. But he still hesitated, he muttered harshly under his breath, "Bloody basilisk down there!"
Harry finally looked determined, he gave Ron one last pleading look. They seemed to share the same thought because Harry jumped in and right on his tail was Ron.
Alex's vision swirled and changed. She was watching Harry and Ron crying over a corpse. Ginny's corpse. She lay dead at their feet. Harry looked over to the journal on his left and a young Tom Riddle who was laughing at them. Harry stood and ran towards the dead basilisk. He grabbed a tooth and stabbed the journal. Just like the story should be. Except, because of the boy's hesitation. Because of Alex telling them the truth. Ginny was now dead. Alex felt tears slide down her cheeks and she closed her eyes.
She opened them to find herself in her dorm. Her hair was sticking to the sides of her face with sweat. She sat up and saw the sun just barely over the horizon.
"What cowards. I've really fucked the timeline, and this time it cost Ginny's life."
Alex noticed her roommates were still asleep so she decided to take her shower before they could interrupt her, or run away in fear.
After taking a shower she put on her pants and tucked in her shirt. She left her new Slytherin loose around her neck. She wouldn't get in trouble but a strict teacher would yell at her to tighten it back in her old world. Thinking back to her old life she had a new resolve. She had to save every life she could possibly save, so people wouldn't have to suffer painful deaths as she and her brother had.
She grabbed her school bag and walked out of her dorm room. Nobody was in the common room so she didn't have to interact with anyone. She got out into the dungeon hallway.
Alex had a destination. She had a goal now. She was headed towards the Griffindor tower to scold Ron and Harry. She passed a few students who decided that the floor looked more interesting than watching where they were going, so she witnessed some students walking straight into walls.
She passed a first-year Griffindor student with a black eye being supported by two other students with busted lips and red cheeks. Those students ran away from her in fright. There must have been a fight in the common room, she could hear the commotion from outside the painting. Another two students with messed up clothes and black eyes rushed out the painting not even bothering that Alexis entered right after they left.
What she saw surprised her. Her brother standing over another student with Harry Potter holding him back so he couldn't hit the student again. Peter looked furious. Alexis knew the argument must have started over her, otherwise, he wouldn't be so angry.
Nobody noticed her entrance so she hid behind some students watching. The kid on the floor shouted, "You both are bloody cursed! You're evil! You shouldn't even be in Griffindor! You belong in the dungeons with the snakes and that wretched sister of yours!" After he said that Peter broke out of Harry's hold and started beating the boy's face. Alex stepped forward and the students she hid behind coward away from her at the sight of her white hair. She passed Harry and gave him a nod of thanks. He stepped back.
Peter was still beating on the boy until now but Alex placed a hand on his shoulder. Peter immediately stopped. He looked over his shoulder and saw his sister. He stood up and kicked the boy away. Peter and Alex were the same height so when they looked at each other their eyes locked.
'Stop hurting people based on their small words. They can't hurt us.' Peter read my thoughts again. He nodded and fixed his sleeves that he had previously rolled up. Harry handed him his bag and Peter and Ginny left the common room together. I stopped Harry from following him. Naturally, Ron stayed with Harry.
Some students in the common room were waiting for more action but were disappointed when they saw Harry and I get along well. The common room was soon empty.
"Boys, I need to speak with you about a change in the timeline."
At the mention of the timeline, they both stiffened.
"Ginny dies."
"What!" They both yelled at the same time.
"Hear me out," They stopped talking, "You boys knew what was in the chamber this time so you hesitated to jump in. This hesitation was the last bit of time that let Ginny slip away."
"So because we hesitated, Ginny died." Harry was dumbstruck. He couldn't wrap his head around the fact that he hesitated. That wasn't Griffindor of him at all.
Ron looked pale again. The thought of losing his baby sister was unbearable for him. He looked determined to change his sister's fate.
Alex interrupted their thoughts, "I've decided to help you take down the basilisk."
"How? It's not like there's a book for how to fight basilisks. Is there?"
"No there isn't unless you want to count Gilderoy Lockhart's fake books then no. I want to enchant a weapon that will aim for certain parts of the basilisk so I can blind in first. I'm thinking of a bow and a set of arrows. I need to know what weapons you boys think you can handle. So I can make you some suitable equipment."
Harry answered for Ron and himself, "We should both be able to use our wands, thanks though."
"Suit yourselves." I shrugged. It's not like I'm going to let them die, they just won't be much help in the fight.
"That's extremely difficult! You're just a first-year how can you know how to enchant anything?!" Ron seemed unable to believe Alex's claims that she could make a suitable weapon for fighting the basilisk.
"I think you forget who you're talking to Ronald. I'll see you boys, later. Oh, and thank you Harry for trying to help my brother."
"No problem."
I left their common room and headed to the library to look for Hermione. Alex wanted to ask her if she knew any books or a section of the library dedicated to researching different weapon enchantments. Although Grindelwald taught her a lot about enchantments they were most deadly and aimed to kill humans. She needs enchantments to kill a basilisk.
She spotted Hermione at a table surrounded by books on Herbology.
"Hermione."
"Huh? Oh, Alexis. Nice to see you here. Do you need anything? Books?"
"Yes, actually I need to know if there's a book here about enchanting weapons. And if there's anything here about killing a basilisk. I've decided to help you, Harry, and Ron to kill the beast."
"Oh. I was going to research basilisks but when you told us we end up winning I stopped. The section for snake research is over there and right next to it are a few books on weapon and armor enchantment. Have you decided you use an enchanted weapon to kill the snake?"
"Yes. Thank you, Hermione. I'll be going now."
We waved bye to each other and separated. The sections she pointed to were in a dark corner of the library and tinted window was the only source of light. I had an hour to kill before my first class so I sat at the window seat and grabbed a book on how to kill different snakes. There wasn't a mention of how to kill a basilisk, just to avoid getting into contact with them.
I read for the rest of the hour. I left the book on the shelve and headed toward the great hall to get my timetable.

Alex headed towards charms for her first class. She was able to avoid the crowds this morning but she wasn't sure she would fend off the spotlight during her classes.

After Gellert Grindelwald’s defeat, his bases were all ransacked. All but one. His own private mansion, location is only known to him. In the basement of said house, Gellert’s secret lab. Two children staying there had all been experimentally infused with different bloodlines. Peter Grindelwald - Metamorphmagus, and Legilimency. Alexis Grindelwald - Metamorphmagus, and Seer. Twins who died in 2018, murdered by their parents. Get transported in the bodies of the two Grindelwald children.

In the Three and a half years after the day that Harry survived Riddle, Sirius has been staying with us in human form playing it out as our uncle trying to make up for the mistake of not being the secret keeper for James and Lily and maybe they would be still alive this made me wonder what is going to happen in the 3rd year at Hogwarts now but I guess we will just have to wait and see how all this will play out. With the news of Harry becoming the boy-who-lived, our grandparents had to reveal themselves back to the wizarding world and for so unknown reason to the outside world they have not returned to the Potter manor with the boy, This is because I had asked repeatedly if it would be possible for Harry and I to be able to learn in a muggle school just like our Mom did until we are old enough to start going to Hogwarts. My Grandparents finally relented and aloud for me and Harry to go to school on the promise that we did not allow for any out of control magic as most muggles are not aware of it. 
A few months after that horrid Halloween Harry had started to get his magic to stimulate throughout his body just like mine does, so that it is constantly nourishing his body to be in the best shape possible and for it to be used constantly this caused the magic in both of our body's to be constantly growing bigger and thee effects just keep compounding because it is a feedback loop. During this time the both of us had started trying to use magic, it was simple things at first like moving a book from one side of the table to the other and back, this took weeks as we had to get the right amount of magic to get the book to lift up just enough that it is not going to drag on the table whilst also moving towards wherever we had to move it to. This was turned into a game between Harry and myself with the winner getting to pick the next thing that we do even if it is just going for a nap to riding our toy broomsticks in the forests near the Greengrass estate(as long as Grandma agreed to that), We moved up from a book to bigger or more awkward things like the table that we were using or the trunk that Sirius had in his room, we had to stop using that after we caused it to flip open in one of our attempts and there were adult mags from both the muggle and the wizarding world now scatter all around the room. With the loud bang from the trunk being dropped barely a second had passed until Grandma had apparated at the entrance of Sirius' room only to be shocked by the both of us trying to stand the trunk back up without touching it and appalled about the fact that Sirius had those types of magazine's "Boys what are you doing in here and what was that loud bang" Shifting uncomfortable under the stern gaze we tried to run out of the room only for the both of us to start running on air and then made to face Grandma again. 
Sat at the dining room table with my Grandparents sat at either end and Sirius sat opposite me and Harry, "Sirius after this we need to have a long talk, but first boys what were you doing to cause a loud bang from your uncles room" Grandma says with a sweet smile that can even cause Dumbledore to shiver 
" We were practising using magic, we started with a book moving it from one end of the table to the other but we were having trouble with it so we turned it into a game so that it could be fun while we did it were one moves the book from one end to the other while the other one trys to stop it. when we found that it was a bit to easy we did it from the sides of the table while leaving the book at the end to make it harder." I started to say, "We then moved onto bigger or heavier things and whoever won chose what we did next, like the few times we asked if  we could use the toy broomsticks in the forest" Harry continued on.
" We slipped with our control while we battled over who had the trunk causing it to fall and open up, that was the loud banging sound. Also uncle Sirius you should think about getting a Girlfriend because that seams to many mags for one man" I finished stating what happened before we were all dragged to the table for this 'chat' "so why did you try and run when I appeared" the female Potter retorted at us when we finished our speech, " I thought that we would be in trouble so I tried to run away I think Harry was just following me, are you mad at us" I said while trying to act cute to diffuse the situation. " Just make sure that you don't go overboard with the games as i don't want you to get hurt because of something that we could help you with, just let us know when you are going to do magic so that one of us can keep an eye on you" Grandpa states for the first time during this discussion and Grandma adds " also make sure that you don't use magic in front of muggles or the ministry will have to get involved" 
Now here we are Harry and I walking through the forested area near the Greengrass estate in the middle of August after our fifth birthday and after reading up on all of the spells that we would be needing to learn during the first couple of years at school we normally end up playing a game of tag where we both try to hit the other with Petrificus Totalus (the full body bind curse) this helps with our reflexes and getting used to being able to use spells while under pressure, we have got better at it but when ever I asked Grandpa to join in so that we could feel the pressure of a more experience wizard but we always end up caught within the minute after he gives us a head start to be able to get as far away from him as possible even when we run in opposite directions every time we ask him to play. 
Hours later Harry and me are slumped over leaning on a tree in the forest trying to catch our breath back and eat the snacks that have been packed for us that we left at the tree just in case we caused the bag to break, we hear a scream not to far off but closer to the magic barrier around the Greengrass manor. As we hear this we look at each other, bolt up and run towards the scream just thinking that it was just some one falling down a hill or something and we were just trying to make sure that they were ok, unsure if the person was a muggle or not we did not use any magic to start of with just incase, as we reached a clearing we stumbled upon a girl about our age backing up on her hand and knees while trying to get away from a juvenile mountain troll (about 6ft tall) until she backed into a tree. with the fear griping her she did not ever contemplate moving around the tree to carry on running away and just started crying. 
" this is bad, this is bad what do we do, what do we do" Harry stammers after all we have not had to deal with this situation before 
"Harry, Harry, OI Harry go home get Grandma and Grandpa I will try and get that girl and run away as long as I can" I shouted as I was shaking his shoulders, this snapped him out of it for him to start shouting back " but what about you we should both grab the girl and run that would be better that way" 
" we can argue later just run get Sirius if you see him first, wait Sirius that's it OI Kreacher, Kreacher we are in trouble help come here" with that there was an loud pop as an angry Kreacher appeared in the woods " What can I do for you young master Potter"  "grab that girl and take her to my Grandma please and then come back here to grab Harry and then me and take us back to our Grandma as well but we might be in a slightly different place when you come back because we will be running away from that thing" I ask as I point towards the Troll that is ambling towards us " Harry how good have you got with the Bombarda spell because we are going to be using it a lot right now, if you can't do it without a backlash just use Lumos as bright as you can at the Troll's eyes" as this conversation ended the Troll roared nearly deafening us because Kreacher had picked up the girl and disapparated back to the house I hope. With the roar from the Troll as the mark I sent two chantless Bombarda spells at the left knee of the Troll hoping that it will make it slower and maybe cause enough damage to the Troll at the same time, with that the Troll followed me as much as it could because I was smaller and was able to get into gaps that it could not follow because of its size plus with the constant barrage of Lumos spells causing the Troll major problems as it could not see me properly, it was all going well until Kreacher had taken Harry back because that meant that the Troll was focused on me now and not turning around looking for Harry after he had blinded it for a few seconds. I lost awareness of my surroundings long enough to get my leg caught is a couple of exposed tree roots and hit my head hard on the floor, the few seconds that I was regaining my bearing of the situation I turned over to look for the Troll for it to be towering over me about to stamp down on my legs with a massive grin across its face. This caused something to snap in me and every bit of magic energy in my body was forced into a single point and fired out of my body towards the Troll and I passed out unaware of the outcome after that.                                  

*** Defence Against the Dark Arts class

Almost before Harry could get a glimpse, Voldemort exited Harry's mind. Quirrell's face snapped to look at Harry incredulously.
Remembering what he had read about kids making accidental protections, Harry pretended to be doodling on his parchment, he doodled walls and cannons and drew a knight for good measure.
Quirrell/Voldemort carefully entered Harry's mind again and this time found the wall and the cannons, firing in the opposite direction, as well as a knight riding a unicorn and a Dumbledore-esque old wizard brandishing a wand in squiggly motions that were obviously not real spells.
Voldemort carefully exited Harry's mind, his relief that he hadn't been discovered was enough to give Harry enough proof that he had managed to fool Voldemort into thinking he was daydreaming.
He almost slumped back into his chair before remembering that Quirrell/Voldemort was still sitting at the front of the class and observing him, while continuing his stuttering act, which Harry could see through easily, now that he knew it was Voldemort who was lecturing them.
Harry resolved to find out what sort of dark magic Voldemort had used to look like the Defence professor. After considering, he decided that it was also possible that both Quirrell and Voldemort were in the same body. Either way, he decided to keep an eye on Quirrell and research what The Dark Lord was doing to impersonate/possess him.

*** Library

After Defence, Harry rushed off to the library, walking fast but not fast enough to seem in too great a hurry.
He got to the library and found mainly 5th years and above, with the occasional 3rd year floating around.
Them and Hermione Granger.
The girl had been in his defence class with him and had gotten to the library even faster than he had. Hell, she seemed to almost live in the place anyway.
She peered over her thick book, "Harry, what are you looking for!" she said bossily.
"Come on, I'm nearly done with my book on supplementary Potions. I could help you research whatever you're looking for."
Harry smiled at the pushy girl and declined, "Sorry Hermione, I'm just doing some general looking, I don't need your help."
"Come on, I can look with you." Hermione looked at him hopefully.
Harry realised that staying in the library all day, the one place where literally no first years apart from himself and Hermione had come yet was probably not the best place to make friends or socialise, Hermione was probably just trying to befriend him.
Harry felt his heart go out to the poor girl. He could sympathise with Hermione, because he didn't have any friends either and before he learned that Dudley was preventing everybody in his school from befriending him, he would also talk to others who went to the library, hoping to find a friend.
With a sigh, Harry decided that he would talk to Hermione. His analytical side screamed at him that it would be wasting time and he would need to make explanations and waste valuable research time, but for the first time in 3 years, Harry decided to ignore his analytical side and just go with his impulsive response to just accept her help.
With a start, he realised that he had been staring at her for a full 10 seconds.
He grinned sheepishly, "Sure, come on and I'll tell you what I've been reading about."
Hermione smiled, hoping she had made a friend and moved to stand and walk with Harry.
They started walking and Harry started towards the section on the mind arts.
"I've been reading up on Occlumency and Legilimency, I've progressing quite well on learning some Occlumency."
Hermione looked at him weirdly, "Occlumency is supposed to be really hard to do and it's almost never given to anybody under 15."
"It's actually easier the younger you are, because the imagination part of it, is far easier when you are younger and have a better and less restricted imagination. The reason many people think that Occlumency should not be taught to children is because it requires a large amount of patience and focus to keep your shields up and many children tend not to have the required concentration time."
Harry gave Hermione a short appraising look.
"People who read a lot of books, specifically non-fiction tend to be able to concentrate better as well as people who are focussed enough on one activity to spend lots of time to become good at it. The kind of meditation that this kind of concentration is required for, is also integral for the animagus transformation and wandless magic."
Harry looked back at Hermione who was looking almost hungrily at him, ready to absorb more knowledge.
Harry laughed, genuinely.
"I'll lend you some of my books."
Hermione enveloped him in a crushing hug and it took all of Harry's self-control not to stiffen and to sort of return the hug.
Hermione separated and blushed, "Sorry, I'm just really happy, I love books." She explained as if Harry was somehow unaware of the fact.
"Just make sure that you're reading the right books and not speculation or opinion posed as fact." Harry cautioned her.
Hermione looked somewhat offended, "Books are meant to tell the truth!"
Harry sighed at Hermione's naiveté.
"Anybody can write a book; it doesn't have to tell the truth. Make sure that other books can corroborate the stories and that you know where the information is coming from."
Harry looked at Hermione seriously, "Believing things you are told blindly can be the biggest mistake you ever make."
Hermione nodded numbly and opened her mouth to counter argue but closed it again. Harry's points were fair, and the emotion she heard in his last statement sounded like he had some experience.
"Fair enough, I will." Hermione found herself agreeing to Harry.
Harry smiled again, deciding to share his topic of research with the avid researcher that Hermione was. She might not have the general smarts that Harry did, but she was a much faster researcher than he.
"Today in Defence class, Professor Quirrell tried to use legilimency to enter my mind. Only, when I managed to stop him and he left my mind, I saw a glimpse of his face… and it wasn't professor Quirrell, it was… Voldemort."
Hermione looked at him sceptically, "But Harry, you killed Voldemort." She said as if talking to a toddler.
Harry shook his head, "I'm sure of what I saw, it made my scar hurt too."
"Just because you got a headache doesn't mean Voldemort is Professor Quirrell, you're the one who told me to check my facts."
"Trust me, I know what I saw, Voldemort is either impersonating or possessing Quirrell. If there was any way to show you, I would."
Hermione looked at him considering, "There is an heirloom pensieve in the Headmaster's office, I've read about it in 'Hogwarts, A History', we could sneak into Professor Dumbledore's office and take a look at your memory."
Harry rolled his eyes and shook his head, "One: It's stupid to even try to get into the Headmaster's office, 2: we'll get caught almost immediately, there's no way that idea would work."
"Oh." Hermione said, somewhat crestfallen.
"But your idea does have some credit, only, I can ask Griphook, whether I have a pensieve in the Potter vault and whether I can retrieve it, otherwise I can buy it, they're supposed to be expensive, but really useful and I do have the money."
Hermione took a long look at him, "Okay then, if you can obtain a pensieve and prove to me that Voldemort is back, then I'll help you research." Now looking a whole lot more frightened as Harry had expected her to be, the possibility finally sinking in, that the greatest Dark Lord of their time could have returned.

*** End of Chapter

"From his own experience, Harry knew that luck had never been on his side. At that moment he decided that he wouldn't rely on luck to solve his problems, he had to become smart, beyond the norm and talk his way through life. That's the only way he could survive."

Dumbledore is confused. If only Harry Potter is not a Hufflepuff, he might be suspicious of Harry. Harry Potter is charming, like young Tom Riddle. He is smart and all of his teacher like him, including Severus Snape, who can't say anything bad about Harry, because the boy did study hard and his performance in class is not behind Hermione Granger, the Gryffindor golden girl, who's he's friend with.

But, Harry is friends with everyone, from a muggleborn like Granger to Death Eater son like Nott and Malfoy. The Malfoy boy even try to conceal bullying from his fellow Slytherin in order to stay friends with Harry.

Dumbledore has give Harry Potter his new invisibility cloak, but the boy has put aside his cloak and focus himself on enjoying his holiday. He did not try the cloak, nor he use it to wandering around. Headmaster Dumbledore has been waiting for Harry in vain. He even put some mild spell on the cloak, so that Harry would come and seek the Mirror of Erised.

Dumbledore put the infamous Philosopher stone that he got from his friend, Nicholas Flamel inside the Mirror. He is planning to teach Harry how to fetch the stone from inside the Mirror.

But, Harry Potter never come.

***

When news of Black and Pettigrew come to Hogwarts, the other students has just arrived back from their holiday.

Harry feigned ignorance of the news. Everyone try to express their sympathy for Harry. To think the ministry put the wrong man in Azkaban for years. What an awesome law. Nobody is happy. But, Minister Fudge put the wrong in the previous minister, and even managed to drag down other people with him.

Headmaster Dumbledore has not been seen in Hogwarts for days. The Headmaster is busy explaining himself to the magical world about his involvement in Black case. Harry use the opportunity to go see the Mirror of Erised. It is located in an unused classroom in the 3rd corridor near where Fluffy, Hagrid's Cerberus is.

Harry has been wondering about what will he see in the Mirror. When he put himself in front  of the Mirror, it reflected himself, clearly. He tilted his head sideways, his reflection just blinked at him, then put his hand inside his trousers pocket. The stone is in his hand, in the Mirror, his reflection put the stone back at Harry and he felt the stone in his pocket. 

Harry take another stone from his breast pocket, he locked eyes with his reflection in the mirror, then drop the stone back in his pocket. The weight of the stone is missing in his pocket.

Done.

***

Iris and Harry walk down a little pathway that is headed for an old stone building. It's night time, so that people won't recognized that there is 2 kids wandering around in the dark.

They stop outside the buliding. The old house look abandoned. Harry knocked the door firmly. Silence follow the knock. 

Not long after, the door creaked open. A young man around 30 something show up, "Yes?" he asked, looking surprise to see 2 kids on his front door.

"We're looking for your master." Iris said.

The man look up and down on Harry and Iris and ask again, "Did you get lost?"

"We're looking for Voldemort." Harry said, making the man freeze. 

He laugh awkwardly, "I don't understand."

"He will." Harry nodded at the other man behind the first man.

"Potter and Swan." the man said, "What a surprise."

"You look better, Professor." Iris wave cheerily at Quirell that stand behind the door, hiding in the dark.

"Come, the Master want to see you." Quirell beckoned the kids.

Harry and Iris walked inside the house. The door closed behind them.

***

The first time Harry Potter repeat his life, he thought he got a second chance to fix everything  and save everyone.

The second time it happen, he thought that life (or is it death) must be play a joke at him.

The next time it happen again, he just feel tired and want it all to end.

Now it happen, Harry is surprised to find a little girl he never seen before.

"You've done it all wrong." Iris Swan said while giving Harry devil eyes, "you're saving the wrong people, making win the wrong side."

Harry is dumbfounded.

My Butler dropped me off at King's Cross Station and i found my way to Platform. It was easy to find the platform, if you had a sharp eye you would see people suddenly disappearing while running, though i was sure there were Ministry issued Oblivator nearby so as to handle any unforseen circumstance of a muggle noticing this.
You can easily differentiate between Muggles and Wizard by their different activities and way of clothing, i am pretty sure i spotted quite a number of Aurors, probably keeping watch for Sirius Black. How big of an idiot they were, like an escape convict will strike at the very place he is expected to.
I knew that Black was innocent or something along that line, i remembered that he dies in one of the later films i think the fifth or sixth one and people were mourning about his death online, so he must have been innocent or atleast on the side of Harry. 
I am in 3rd Year so this is the Prisoner of Azkaban, well what do i remember about this year, hmmmmm, i remember that they had a good new teacher this time, sirius black escapes, werewolf something which was in the trailer of the movie and dementors ohh yeah dementors, they will come to Hogwarts. I had researched about Dementors in the holidays. The thing is not much is known about them. History book just say they were there one day. They need to feed thats why they stay at Azkaban, its a sort of compromise they have with the Ministry. Ministry gives them prisoner to torment and feed themselves on while they remain at Azkaban and don't bother normal folks.
Only way to defend against them was the Patronus charm, the incantation and wand moment of which were easy but the spell itself was difficult mainly because it required happy memory, a memory which will put a smile on your face the very second you recollect it, the memory must be pure too, you can't have memory in which you are taking revenge against someone be used for making Patronus. Thus the reason that not many people are able to master it. But i figured out a theoretical way to make patronus, nowhere does it say that the memory has to be real, why can't you use the memory of your favorite dream or make up memory. Making up memory is easy, especially if you came from the 21st century where people used to fake their lifestyle on social media, you know how to make things look a certain way so that you can have others be jealous of it as well as show off and satisfy your own vanity, Instagram influencers were the prime example of it. I still need to test my theory though, can't quite cast charm like patronus wandlessly and with wand the trace would have come to effect.

Holding onto my Walkman listening to music i made my way through the Hogwarts Express looking for some empty compartment. Finally found one with a man lying probably sleeping. He had covered himself with a shawl. Placing my stuff i looked around to get a glimpse at the person's name, Remus Lupin, which was written on a suitcase.
Must be the new professor, atleast i know that he is capable as far as i remember most of the teaceher in Hogwarts were abysmall at there jobs especially the DADA post which had new professor everywhere. 

I had just settled when i noticed the compartment door being opened, I saw Hermoine, Ron and Harry,The Golden Trio. Should i be close to them or stay away i had no idea, i had not decieded what to do so lets just go with the flow here.
Hermoine's mouth moved and i realised that i still had my headphones on, silly me.
"Hey, sorry i was listening to music" i replied.
"I was saying, can we sit here Blake, everywhere else seems to be full." asked Hermoine.
"Sure no problem." I replied.
"Hermione, who's he?" asked Ron.
"I think its proper manner to introduce oneself before asking others for introduction." I spoke looking at Ron.
Hermoine jumped in and pointing towards me said, "He is Blake Rivers, a muggleborn like me and Syltherin. We have been exchanging letters and notes since the end of last term" then turning said" The red haired boy is Ronald Weasley, and the boy with glasses is Harry Potter."
"Hermoine, He's a Syltherin how can you be friends with him? all of them are prats"Ron exclaimed with horror.
"Ouch,Weasley, Judgemental enough? I can say that this quality of judging people before even knowing them is kinda Slytherin like." I spoke with a smug smile.
Color drained out of his face for a second and then i turned towards Harry
"Thanks for dealing with the little snake problem we had last year."
"Thanks, i didn't do it alone, i had help especially from Hermoine." he replied.
"Well i am going to go back to listening music, so don't worry Weasley i wont be disturbing you." saying so i put my headphones back on.

After some time, Hermoine tapped on my shoulder.
"Yes, Hermoine?" i asked
"Why are you taking the walkman with you? you know that electrical devices don't work at Hogwarts?"she said.
"What?????" I shouted.
"Yeah,mate. Nothing electrical works at Hogwarts. You didnt knew?We were told that in the first year" Harry said while clearly amused at my outburst.
"I lost my memory after the "Snakey Incident" last year." I told him while clearly drowning in my pain of going through the hard work of recording tapes of all my favorite 80's song.
"Oh, Sorry."replied Harry.
"No need mate, it was actually a good thing, losing those memories gave birth to Blake 2.0, and let me tell you this Blake is better and badder." I told him while standing up doing a 360 round circle and shouting "BE BAD!".(A/N:I was listening it at the time of writing this so i just added it here.)
Harry and Hermoine laughed clearly understanding my reference while Ron sat there thinking that we had clearly gone mental.
Suddenly i felt cold.
"Um, guys do you feel cold?" I asked.
The train stopped, the temperature dropped becoming cold,droplets of water condensed on the windows
"Oh shit its the Dementors" i shouted.
There was a collective gasp by Hermoine and Ron who clearly understood the danger. Whereas Harry sat there completely oblivious.
"What is a Dementor?"asked Harry.
"Something that you don't want to be near of."replied Hermoine.
Suddenly the temperature dropped even more and the door of compartment shot open. A black clothed figure/skeleton made its way in.
I think anyone who sees it for a first time will be frighten but i was fascinated, how did they live, did they have organs, brain, were they sentient or just lived by instinct like animal.
The Dementor seemed to have taken a liking to Harry as it was moving towards him.
Instinctively or reflexively i am not sure, i reached for my pocket and grabbed my wand and shouted,"EXPECTO PATRONUM", while focusing on a number of fake memories i had made.
White Mist came out from my wand enough to distract the Dementor but not corporal enought to completely take it out.
Suddenly Lupin jerked awake and performed Patronus to drive away the Dementor.
I collapsed as soon as Lupin drove it away, Magical Exhaustion is real guys.
Remus took out chocolate from his coat and handed it to Harry and Me.
"Great display of magic over there MR?"
"Rivers sir, Blake Rivers." I replied while munching on the chocolate, it tasted like the best thing i ever had.
"Eat slowly, Blake, chocolate helps in dealing with Magical Exhaustion and Mr. Potter you too" turning towards Hermoine  he said,"Can you look after them both while i go and have a talk with the driver?"Saying so he left.
"Mate that was something you did there." Ron said looking at me clearly with awe.
"Why do they even have Dementor here on the train?" asked Hermoine.
"For Harry."i replied while munching on my chocolate bar and ready to kill anyone who wants to take it from me.
"ME??Why?"asked Harry clearly surprised.
"Well, (A) He was a death eater whose master was killed by you, (B)Hogwarts Express is the only place he can attack you at, the wards at Hogwarts make it almost impossible for him to even enter so this is the only place he can attack you." I replied while not even looking at their reaction.
"Can't i spend atleast one peaceful year at Hogwarts without people trying to kill me." I heard Harry whine.

Disclaimer: I own nothing. Harry Potter, its character and its world all of it is owned  by J.K Rowling. This fanfic is just a fans idea of a story.

A/N:I will insert 21st century and music in the story, so dont complain that the song was not even out then or that reference doesn't make sense. The purebloods would never have understood muggle references anyway.
