Summary: AU – After meeting with the Headmaster, Harry meets a strange woman that says she can change the past to a better future with his help. Will Harry help her change history to a better one and help those who were in need of help in the beginning?

I don't own Harry Potter. All credit goes to J.K Rowling but I do own my OC, Yuki.

Pairings: Lily x James, Sirius x Mary, Remus x OC, Severus x Aurora, Bellatrix x OC, Lucius x Narcissa, Andromeda x Ted, Regulus x Petunia, OC x OC, Fabian x OC and Gideon x OC

-Slytherin Manor, night-

"I can't believe those old coots returned!" shouted Yuki, angrily. She grits her teeth, "Not only that but they attacked my family! Oh so Hell's Gate, when I see those blasted wizards I'll…"

Harrison stopped his mother's ranting before addressing to the others. He sighs, "Who remembers Albus Dumbledore and Gellert Grindelwald?"

"Wasn't Dumbledore the previous Transfiguration Professor before me?" said Minerva.

"And wasn't Grindelwald the last known Dark Lord?" said Charlus.

Harrison nodded.

Fleamont frowned, "But didn't they vanish from the Wizarding world many years ago?"

"Yes," replied Yuki, darkly. Her eyes turned dark crimson, "After Armando gave Albus a time-off to take care of his little sister, Gellert disappeared. Sometime during the summer, Albus' sister died from her illness and Albus vanished as well."

"No one has ever heard or seen them for a long time," said Harrison. He sighs, "Not even Albus' older brother, Aberforth heard anything for many years."

"Until now," murmured Alexander. He crossed his arms, "So what's the deal? What are they looking?"

"The Deathly Hallows artifacts," hissed Yuki.

Bellatrix widened her eyes, "I thought those artifacts were just fairytales from that storybook!"

"Oh, they're real dear," said Liza. She walked over to the shelves and pulled out a familiar children's book. The young Vampire smiled, "My Father met the Peverell brothers before they meet with Death."

Everyone widened their eyes.

"Not only that but the Potter's and the Gaunt's are direct descendants to two of the three Peverell brothers," stated Yuki.

Everyone was in complete shock.

"S-So if the Deathly Hallows exists, why Dumbledore and Grindelwald want with them?" asked Regulus.

Harrison sighed, "Albus wants to use the stone to bring back his dead sister while Gellert wants to become the most feared wizard in the Wizarding committee…and the muggle committee."

Euphemia widened her eyes, "If Dumbledore only wants to see his sister, why does he follow that dark wizard, Grindelwald?"

"…You see, that old coot blames the muggles for his sister's death," replied Yuki as everyone gasped. She sighs, "Ariana Dumbledore was taken to a muggle hospital since the Dumbledore bloodline were quite known to be a grey family. When Albus and his siblings were younger, their parents killed off a few muggles and afterwards, their bloodline was tainted. Sadly…Ariana died at the muggle hospital, she was too ill to be saved from muggle or magical practice…Albus vowed to avenge his little sister's death."

Petunia gasped, "That's horrible! He can't do that! It's not the muggles fault if they tried their hardest to save Ariana's life!"

"The stone...a red stone?" murmured Salazar before widening his eyes. "The red stone inside Merlin's Vault is the Resurrection Stone, Grandfather?!"

Harrison nodded, "Not just the stone but the cloak and now the wand are protected inside Merlin's Vault."

"You're collected all the three Deathly Hallows?!" said James and Sirius.

"Does…that mean you're the Master of Death, Great-Uncle?" asked Severus.

Yuki shook her head, "Since Harrison disarmed Gellert, he owns the Elder wand or any of his bloodline. The Potter lineage owns the Cloak of Invisibility while Thomas owns the Resurrection Stone since he was originally from the Gaunt's."

The younger children widen their eyes.

"WHAT?!" shouted Alexander.

Thomas sighed, "I was adopted at the age of four. My original birth name was Tom Marvolo Riddle Jr. My birth Mother was Merope Riddle nee Gaunt and my birth Father was Tom Riddle Sr."

Salazar frowned, "So we're not related to…"

"Oh we're related to Lord Slytherin, son," said Thomas, quickly. "But through my birth Mother. Gran-Yuki was blood adopted into the Slytherin bloodline when your ancestor, Salazar Slytherin was alive. She then blood adopted my Father who later adopted me but not blood adoption."

"Why didn't you blood adopted my Father, Grandfather?" asked Salazar.

"I want him to live his life to the fullest and when the time comes, he can go to his next adventure happily…I didn't want to force him in a life of a Vampire," explained Harrison, sadly. He then smiled, "But it doesn't matter if I blood adopt him or not, he is still my son and you are my greatest grandson. Not only that but I have wonderful nieces and nephews."

The children had a smile on their faces.

"Okay so as long as the Deathly Hallow artifacts are in the vault, Dumbledore and Grindelwald can't get them, correct?" said Alexander.

Harrison nodded, "But we'll handle them, understand?"

Alexander and Salazar had an unsure look but nodded. The Black sisters frowned a bit but agreed as well.

-Hogwarts, Sept. 1, 1971-

Harrison watched from the Head table to see his daughter-in-law enter the Great Hall with the new first years. He smirked to see how nervous the young students showed.

Minerva walked over to the brown stool where the Sorting Hat was at. Like always, the Sorting Hat sang his unique intro before getting picked up by Minerva. She looked down at the first year students, "Now when I call your name, you'll come up and I'll place the Sorting Hat on your head. The Sorting Hat will then sort you to your rightful house."

James and the others fixed up their robes or straighten their ties.

"Sirius Alfredson – Gryffindor!"

"Lily Evans – Hufflepuff!"

Harrison widened his eyes as he watched his former mother go to the house of loyalty instead going to the house of bravery. He thought, 'I wonder what changed.'

"David Greengrass – Slytherin!"

"Liana Knight – Ravenclaw!"

"Mary McDonald – Gryffindor!"

"Remus Lupin – Ravenclaw!"

'Another switch…interesting,' thought Harrison as he watched his former honorary uncle got to the house of intelligence.

"Peter Pettigrew – Slytherin!"

Harrison glared towards the slight chubby boy with second-hand robes walking to the house of cunning. He thought, 'At least he was sorted into his proper house. I hope this time he's not a bloody coward.'

"James Potter – Gryffindor!"

"Aurora Sinistra – Ravenclaw!"

"Severus Snape – Ravenclaw!"

Harrison wasn't at least surprise to hear his former professor sorted to his rightful house. He turns to see Tobias having a proud look on his face while Eileen was playfully pouting before giving a proud smile to her son.

After the sorting, Harrison got up and greeted his students. He smiled, "Welcome to new and old. To start, the Forbidden Words are off-limits as there are dangerous creatures living there. Bullying will not be tolerated here. Severe punishments will be given and privileges will be taken if you break any rules, understand?"

The students nodded.

Harrison smiled before clapping his hands where the food suddenly appeared. The young students were in awe while the older ones started to fill up their plates.

Sirius was listening to his best friend and third year, Frank Longbottom when he felt arms on top of his head. He looked up to see his cousin, stand behind him, "Reg, what the bloody hell are you doing here? Shouldn't you be at your table?"

Regulus laughed, "At the beginning of the feast, yes but once the food is out, everyone has free rein to move around if they like."

"Really?" said James.

Suddenly an older boy with dark red hair and light blue eyes appeared to James' right. He grinned, "Little Reggie is telling the truth, little firstie."

Another older boy with the same hair but with darker blue eyes appeared to Sirius' left. He places his arm around Sirius, "It's been like this since Headmaster Slytherin-Fudo took charge."

"Which frankly, it's a lot better."

"Mostly the rivalry between the lions and the snakes."

Regulus sighed, "Don't confuse my cousin with your idiotic twin talk guys. Siri, Jamie, these two clowns are Gideon and Fabian, the Prewett twins."

The Prewett twins got up and took a bow, dramatically. They grinned, "Greetings little firstie lions. We are the famous Prewett pranksters in Hogwarts."

James smirked, "Pranksters?"

"You don't say," said Sirius before getting hit by his other cousin. He growls, "Bloody hell, Cissy! You didn't have to hit me so hard! I didn't even do anything yet!"

Narcissa placed her hands onto her hips, "Not yet but I know that look you were showing. You two better behave or you'll get busted from your parents."

"As if I'm going to get caught," murmured James. He grinned before leaning over to Sirius, "Let's meet up with the others at the seventh floor, tomorrow night."

Sirius nodded before the two continued off with their meals while listening to the Prewett twins comment about their first nephew, William Weasley.

-Hogwarts, Sept. 2-

Severus, Remus and Lily were sitting at a round table with few empty seats available. They were looking over their timetables and eating their breakfast when James and Sirius came to the table, half asleep.

"Try to wake up Potter or you'll end up eating your spoon," teased Severus, playfully. He had his small raven riding on his left shoulder.

"Oh very funny Raven," said James, sarcastically.

"So do we have any classes together?" wondered Sirius. He pulled out his timetable, "We got our schedule this morning from Aunt – I mean Professor McGonagall."

"Well it depends. Ravenclaws and Hufflepuffs have History of Magic and Charms. Gryffindors and Hufflepuffs have Herbology and Transfiguration. Slytherins and Gryffindors have DADA and Potions," said Remus, looking over at his timetable.

"Just the basics," murmured Severus. He sighs, "I can't wait until we are in our third year so we can pick out some elective courses too."

"Aw no fair!" whined Sirius. He pouts, "Now who am I going to cheat off in Transfiguration."

"You don't have to cheat off," said James as he grabbed a glass of pumpkin juice. "I'm pretty good in the subject and in DADA too."

"I guess," said Sirius before looking over the redhead. "Lilypad, you wouldn't mind…"

"Oh no, Sirius," interrupted Lily, angrily. "You better find another partner for Transfiguration. Besides, Auntie – I mean Professor McGonagall will be keeping an eye on the both of you."

James and Sirius paled, "We're doomed!"

"Not unless you study," said Severus.

"But then we wouldn't have time to out prank the Prewett twins!" whined Sirius.

"Out prank?" said Remus.

"Why do you want to out prank the Prewett twins? And who are they?" asked Lily.

James and Sirius started explaining to their friends about the six year Gryffindors before going to their classes. While Lily, Severus and Remus went to History of Magic; James and Sirius went to DADA.

After lunch, James and the others walked up to the seventh floor to find the Room of Requirements. Sirius tries to remember what his cousin, Bellatrix told him on how to make the room appear. He walked pass a hallway, three times before a double door appeared on the wall.

They entered to see the room was like the playroom in Slytherin Manor.

"So how do you plan to out prank two six year Gryffindors?" asked Severus, sitting on a blue bean bag.

"Easy," said James, sitting on a red couch and Sirius sat next to him. He took out a worn out book, "We will be using this bad boy. It has all of these brilliant pranks!"

Remus took the book before opening it and saw it belong to Harrison. He frowns, "Jamie, this book…it belongs to Great-Uncle Harry. Did you ask permission to use it?"

James laughed, nervously, "Um…well about that…"

Lily widened her eyes, "You stole it, didn't you! James! If Great-Uncle Harry finds out that you took it without permission, you'll get in trouble! You better give it back to him!"

"Its fine, Lils," said James. "Most of the pranks potions are standard ingredients, nothing dangerous. The pranks spells are pretty easy and it's not hurtfully at all."

Severus and Lily looked at each other before looking over by Remus' shoulders to see the book. After a few minutes, the two give a thumbs-up, "We're in!"

"Prefect, what about you Remy?" asked Sirius.

"Oh what the bloody hell not," said Remus. He smiled, "It might be fun…though we have to be careful around the adults."

"Brilliant!" said James, happily. "Now turn to page thirty…"

-October, Halloween-

Harrison and Liza were enjoying their Halloween feast but that's when Harrison noticed Eileen was giving an eye on James' table. He lifts up his eyebrow, "What's eating you, Eileen?"

"It's…well, today in class, Sirius and James were actually paying attention and…were too quiet," replied Eileen, suspiciously.

"I agree Father," said Thomas. He narrowed his eyes, slightly, "They didn't even try to prank any of their classmates during this whole week."

"You don't think they are up to something?" wondered Minerva.

Harrison looked around the Great Hall but felt nothing out of the ordinary. He grabs his goblet when there was a sudden shout coming from the left side.

There sitting on a chair was an animal, a pony.

Harrison was about to get up when every single student were turned into animals, including the stuff minus him and his wife. He thought a moment before smirking, 'James must have found that prank book in my study room.'

Liza let out a giggle, "Oh my, looks like little Jamie did something naughty dear."

Harrison nodded before seeing James turn to a young fawn, Sirius turn to a black puppy, Remus turn to a small wolf pup, Severus turn to a young raven and Lily turn to a white owlet. For the older ones, Lucius turn to a white hawk, Narcissa turn to a swan, Regulus turned to a panther and the Prewett twins turn to a set of black and white foxes.

For the professors, Thomas turn to a large snake, Minerva turn to her animagus form – a tabby cat, Eileen turn to a lynx, Tobias turn to an older raven and etc.

Liza couldn't hold her laughter while Harrison shook his head. Knowing that his and his wife's drinks couldn't be mix with potions since it was animal blood. The young Vampire sighs before getting up and walked over to James' table.

The potion didn't last long and everyone return back to normal.

"James Charlus Potter! Report to my office – all of you report to my office, now!"

James and the others paled a bit but nodded. They got up and walked out of the Great Hall.

-Headmaster Office, night-

"What in Merlin's name did the four of you were thinking?!" scolded Dorea. She placed her hands onto her hips, "Brewing a potion without any of us watching?! Did you not think for one minute that something wrong could have happen?!"

James and the others looked down.

"I thought I have taught you better Severus," said Eileen, disappointedly.

"I'm sorry Mother," said Severus as he rubbed his eyes. "But…the recipe…it didn't have any dangerous ingredients so we thought it would be safe to use."

"It's true Auntie Eileen – James, give her the recipe!" said Lily.

Eileen took the parchment from James before looking over at the ingredients. She slightly narrowed her eyes, "You may have a point but never the less – you disobeyed and took something without permission!"

Euphemia frowned, "I'm very disappointed with you James…all of you."

James and the others continued to look down at the ground.

"Ladies, let me handle their punishment," offered Harrison. "It's been a long night and you do need your rest for class tomorrow."

The women nodded before leaving the office. The moment the door closed, Thomas placed a silence charm at the door and the men started to laugh. Liza was giggling, uncontrollably.

James and the others were confused.

"Um…Dad?" asked Sirius.

"Sorry son," said Daniel, recovering from his laughter. Talking a deep breathe, "You see kiddo, your Uncles and I placed a little…wager on how long would it take for James to sneak into Harrison's study without permission."

Charlus smiled, "I placed that prank book on purpose. It original belong to Tom and I. We used it during our time at Hogwarts as well."

"Oh yes, I remember quite well," said Liza, between laugh. "I believe you and Thomas set a world record of the highest pranks set on Hogwarts since Slytherin and Gryffindor themselves."

James and Sirius' mouths dropped while Severus, Remus and Lily laughed a bit.

"So…we're not in trouble?" said James.

"Oh, you're in trouble but not as much," replied Tobias. He sighs, "I just wish that you had a bit more patience. Oh well, looks like you win yet again, Harry. Now what is their so called punishment?"

Harrison tapped his chin, "Well, I don't see why they don't clean out my attic during Winter Break and maybe help Hagrid a bit."

James and Sirius sigh in relief.

"At least your attic is a lot more fun to clean rather than my parent's," said Sirius.

"Merlin, the last time I was up there, I thought I saw books that are older than Great-Uncle Harry!" said James.

Harrison and Liza shook their heads with amusement.

"Alright you two," said Tobias before giving a proud look towards his son. He smiles, "Great job making the potion, Sev and Lily. I take it that Remus took the potions to the kitchen, yes?"

Remus rubbed his head, sheepishly.

"Well then, off to bed, all of you," said Thomas, clapping his hands. "You have class tomorrow…do try to look at least hurt when you try to sit down, got it?"

James and the others nodded their heads before heading out the office.

Daniel smiled before sighing, "Char, remind me never to bet with Harrison – ever again!"

"Here, Here," said Charlus while Thomas nodded.

-Hogwarts, 1975-

The past four years, much as not changed.

In October 1971, Ted Tonks married Andromeda Black. They continued college for two years until Andromeda got pregnant. In 1973, Nymphadora Tonks was born.

In December 1971, Aiden married Alda McKnight. Aiden became Second Head Vampire while Alda is going under training to become the first Headmistress Vampire. The last one perished a few hundred years ago.

On 1972, Arthur and Molly Weasley had another child and named him Charlie. Lastly, December 1973, Salazar married Bellatrix Black.

Harrison sighed as he placed the parchment into his robes. He then looked down at the young girl beside him and placed his hand over to her shoulder, "Well, shall we make a grand entrance, young lady?"

The young girl, who has straight rosy gold hair with small curl at the bottom, has large pale green eyes and has light tan, smooth skin. She was slight short for her age but didn't matter to her since her mother was also short. She had long, pointy ears, strange tattoos all over her arms and legs though on her face, under her eyes were curved triangles and around her head was a circlet.

"S-Sure, Headmaster but…but are…are you sure that I'll be safe here?"

"Positive, shall we?" said Harrison before guiding the young girl inside the Great Hall.

The students stopped what they were doing as they watched their Headmaster walk with a lovely girl up to the Head table. Minerva walked over to Harrison's left with the Sorting Hat.

"Everyone, can I have your attention please? Thank you. Now, I would like to introduce you to a very special young lady. She came from Scotland…unfortunately; she had to leave her homeland for her safety. Her parents entrusted her to me to keep her safe and continue on with her education. Minerva, if you please."

"Avalon Marshall!"

Avalon felt the old hat being placed on her head before jumping a bit when she heard a voice in her head. She bites her lip, "Hello, Mr. Sorting Hat."

"Ah, a well-mannered child, hope you can educate some of these students child and the name's Leo. Now, where do I sort you?"

"I don't have a particular house. Just as long I can feel welcome and can make great friends."

"Yes, yes, it's all in here in your head. Trust in the Headmaster child, just like your parents did before you – Hufflepuff!"

Avalon smiled a bit as Minerva removed the hat from her head.

That's when Lily came over to her and gave her a warm smile. She offered her hand, "Come, you can sit with me and my friends. I'm Lily Evans, fifth year Prefect Hufflepuff and welcome to Hogwarts by the way."

"Thanks," said Avalon, letting Lily guide her to a round table with other students. She sat next to Lily where she introduced her to her friends.

"James Potter, fifth year Prefect Gryffindor!"

"Sirius Black, fifth year Gryffindor at your service, my lady."

"Mary McDonald, fifth year Gryffindor, nice to meet you."

"Severus Snape, fifth year Prefect Ravenclaw."

"Aurora Sinistra, fifth year Prefect Ravenclaw."

"…Remus Lupin, fifth year Ravenclaw…"

"Regulus Black, sixth year Head Boy Slytherin, greetings."

"Frank Longbottom, seventh year Head Boy Gryffindor. If you need anything, don't be afraid to ask any of us, got it? And welcome to Hogwarts."

Avalon smiled, "Pleasure to meet you all. Headmaster Slytherin-Fudo said that one of you could show me around the castle."

Sirius was about offer when James stopped him. The Gryffindor Prefect winked, "Remus will do it, right Remy?"

Remus unknowingly nodded before turning his head towards James. "Wait – What?! Why not you? You're the bloody Prefect!"

James leaned over to Remus, "And you lose your chance for a girlfriend, I don't think so."

Remus blushed before addressing to Avalon. He stuttered, "If-If you like I can escort you to your classes…"

"Thank you Remus," replied Avalon, warmly.

Remus bit his lip before looking down at his plate with crimson cheeks.

That's when Sirius noticed something. He pointed towards her tattoos, "So what's the deal with those silly markings anyway and pointy ears?"

"Oh, these silly markings are my magical tattoos from my Elven inheritance," replied Avalon. "It's quite common for young Elves to get these tattoos at the coming of age ritual. Mine was done this summer…before…before they attacked…"

"Who attacked you?" asked Regulus.

Avalon bit her lower lip, "…there were two elder wizards…I believe their names were Dumbledore and Grindelwald."

James and the others widen their eyes.

"I take it that your parents know the Headmaster, correct?" said Frank.

Avalon nodded, "Well, my mother and his mother know each other. Lady Yuki would sometimes bring her son to our home and help me train while my mother and her would do things together."

"What did your mother do?" asked Severus.

"She works with ancient old magic, creates magical books about rituals and create any kind of magical artifacts," replied Avalon. She smiled, "I can't wait to make my own weapons and wands when I'm older. Maybe even make my own store someday."

James and Sirius whistled.

"That's quite a dream Avalon," said Remus. "But what about your mother? Will she be alright?"

"Yes, she's fine but she wanted me to come here for the time being," answered Avalon, sadly. "Lady Yuki is trying to help my mother to hide from those two dark wizards."

"How long you'll be staying here then?" asked Lily.

"Until I get word from my mother," replied Avalon. "But we wouldn't be going back to Scotland. Lady Yuki offered her home to us until I finish my education here in Hogwarts."

"Oh that would mean you'll be here for Yule Ball," said Aurora, happily. She leans over to Severus, "I know that you'll be taking me, Sev."

Severus blushed a bit while James and Sirius snickered at their friend. The Prefect Ravenclaw glared at them before smirking, "I don't know what's so funny gentlemen. I mean you are planning to take your 'girlfriends' to the Yule Ball, correct?"

James and Sirius stopped laughing before blushing.

"Oh you better Alfredson!" warned Mary. She glared at him, "And you better not be late! Not like our date, three weeks ago!"

"Alright, Alright…Merlin, I promise I wouldn't be late," said Sirius. He sighed, "…I wasn't even that late…just five bloody minutes…"

Avalon watched as Mary hit Sirius on his head. She looked over at Lily and pointed, "…does…does that always happen…"

Lily sighed, "Yes, so you better get used to it. Come on, it's time to go. It's a good thing that we have class together with the Ravenclaws."

"That's right!" said Sirius, after recovering. He elbows at Remus, "Come on Moony, don't leave your girl carrying her books by herself. Not to mention, you have to show her around."

Remus blushed, "S-Shut up Padfoot! Let's just go guys!"

Avalon giggled before getting up and followed the two Ravenclaws and Lily to Charms. She looked over towards Remus, 'He's…not bad looking. Maybe there is a future for me here in Britain…I just hope my parents come to me soon.'

-Break Line-

Well looks like James and the others had a great time during their Hogwarts years and it looks like Remus might be getting a girlfriend. Will he be able to protect her if Dumbledore and Grindelwald find her again?
