Harry Potter: War Mage

Harry Potter was a great teacher. He made every lesson fun and practical, the ravenette never made any student feel stupid or less than because they didn't know something or were confused.

In the one month since the term began the student body was rapidly progressing in Defense, in ways most of the staff looked at with awe.

The most awe inspiring of Harry's accomplishments was successfully teaching over three quarters of the school the Patronus charm, a type of magic most people thought impossible for children to learn even the bȧrė bones of and many of them could cast a fully corporeal version.

Despite how Harry portrayed himself at the Welcoming Feast, he was kind, considerate, always willing to help, gave extra lessons to anyone who asked and most importantly, the teen was fair with an undeniable soft spot for the entire student body which the Slytherins counted as a miracle since only Severus ever really looked at them with any sort of pride and even then, he bȧrėly liked them.

Harry Potter was a great teacher and everyone knew it. Now if only he looked the part.

In the month of teaching, the first Potter Scion had continued his research with the same amount of zeal as he first began the quest and he felt he had cracked it.

A permanent aging Potion, it was a blend of three potions created as one; an Animagus potion and two different aging potions.

A Mandrake Leaf had to left in his mouth from the start of one full moon to the next, at the same time the base of his new potion had to be made, which consisted of the shedded skin of a Basilisk purified by Phoenix fire, rock salt that was the age the user wanted to be and Newt spleen that was the current age of the user. The potion then would have to be stirred clockwise of a total equal to the new age of the user and then counterclockwise that was the user's current age, this had to be repeated the entire month the Mandrake leave was in his mouth.

After the next full moon, if the sky was clear the user needed to mix the Mandrake leaf and add a strand of hair to the potion before stirring it one final time and then drinking it at the height of the full moon.

Harry had started the process and knew he just needed to wait. "Big Bro!" Evan came rushing towards him in a panic and the ravenette felt his heart squeeze in panic.

"What's wrong, Evan?" The brunette eyes were red and he was clearly out of breath.

"Derek! It's not his fault! You have to believe me! They just wouldn't stop making fun of us! If anyone should be in trouble-" Harry rested a hand on his little brother's shoulder, calming him.

"Where is your brother?" Harry questioned with a calm voice, that betrayed non of his urgency 

...

He was just so angry, how dare that slimy snake call Hufflepuffs the reject House! 

He wasn't a reject! Derek was a Potter! He was just as brave as any Gryffindor! And he proved it!

"AGGAAGHHH!" The wind blew past his face as he climbed higher and higher in the air, the old school broom he took without permission, shaking with effort.

Why did Derek think playing chicken was a good idea? Why was this broom refusing to slow down?!

Why couldn't he let go! 

A moment later his body glowed a bright blue but the brunette was still climbing higher up.

…

Harry rushed to the Quidditch pitch where over a dozen students stood around with worry,looking up in the clear sky.

The ravenette pointed his wand up. "Point Me to Derek Potter!" He exclaimed, a blue light shot out of his wand and quickly left his sight, he quickly realized he had to expand about a quarter of his magical reserves for the spell to reach his little brother.

"Got him!" Harry exclaimed before his eyes widened, "Shite! He's almost in the Mesosphere!"

"What! Brooms can't go that high! There's numerous safety spells!" James exclaimed with shock and worry, Lily felt sick at her little boy so high up. 

"Modern Brooms have those safety spells but Hogwarts haven't upgraded them since the sixties," both parents felt shock run through them. " But Derek shouldn't be able to reach that height that fast, the only way…" he turned to look at the students who took a step back at his intense expression. "WHO CURSED HIS BROOM!" Harry exclaimed with fury and most of the young students looked ready to run. "I need the Incarnation! It's the only way to safely stop Derek! So who cursed him!" No one came forward and Harry balled his eyes tightly.

"Okay." Harry muttered before opening his eyes and canceled his locator spell before pointing his wand towards the ground. "Invenire Maledictus!"  an explosive wave of orange dust encompassed the field before flying towards a second year Slytherin girl, smothering her.

Harry raised his left hand, summoning the child's wand to it and held the tip of his own Blackthorn magical focus towards the child's, "Prior Incantato." A blue mist escaped the second year wand and a word formed.

/Propero/ Harry narrowed his eyes at the spell, he didn't recognize the spell like he hopped. 

"Do you guys recognize the Incarnation?" Neither James nor Nymphadora did but Lily, while like the other ȧduŀts didn't know the spell, could read and understand the Latin Incarnation.

"It means haste!" Harry narrowed his eyes before turning his wand towards the sky and a beam of blue light escaped his wand, stretching hundreds of thousands of miles and draining another quarter of his reserves.

"Morabor!" The blue beam turned a bright red, well he did save a significant amount of his magic as the line of power was already made, his reserves still took a major hit. "Ugh!" Harry felt a sharp pain in his head.

"What are you doing!?" Nymphadora asked with worry as she looked at the line of blood dripping from his nose.

"Movere!" Harry fell to his knees as his magic turned a dull pink and he coughed up a glob of blood, the line of magic dying after the spell was cast.

"Ough! OUgH!" The fourteen year old hacked several more globs, his eyes bȧrėly able to be kept open but he managed to point his wand downwards. "facti pulvinar." Harry muttered and the ground turned into a giant bed before falling onto his face and shook violently as if he was having a stroke, his body unable to handle the amount of magic he was forced to produce coupled with having expended all of his magic.

"Son!" James held onto Harry's body while Nymphadora kneeled beside the boy and scanned him with her wand.

"I… he exhausted all his magic." The junior Auror told the man with clear shock, the more experienced Auror looked close to crying along with his wife and remaining son.

After several long moments Evan saw an almost unseen dot hit the ground-like bed hard.

"Derek!" Evan rushed over with Lily close behind, as the two kneeled next to the unconscious boy, the Potter Matriarch waved her wand across her little boy's body much like Nymphadora did to Harry and sighed with relief.

…

Harry ġrȯȧnėd as his eyes fluttered open and saw a familiar white ceiling. "I hate this ceiling." He heard a snort of amusement.

"Auror Tonks." Harry forced himself into a sitting position only for the woman to push him down.

"Uh no! James told me to keep an eye on you and make sure you stay rested when you wake up." The woman stated resolutely.

"I'm a grown man, thank you." Harry pushed her hand away and sat up, Nymphadora raised an eyebrow and shot him an amused smile.

"You don't look like a grown man." The ravenette rolled his eyes at the woman.

"Blame Voldemort." Nymphadora flinched at the name while Harry took several deep breaths trying to force the pain away. "How's Derek?" Harry asked as he grabbed his wand and flicked it back into its holster.

"He's fine, just a slight concussion." The fourteen year old looked around and saw he and the woman were the only two in the room. "In case you're wondering, James and Mrs. Potter are giving Hell to the Headmaster with the boys." Harry hummed in acknowledgment. "So… did… we know each other in your world?" The pink haired Metamorphmagus, a Magical who could instantly change their body in any way, shape or form, asked with curiosity.

Harry looked at the woman and shook his head. "Nope." The teen stood up before flopping back down, Nymphadora giggled slightly and Harry raised an eyebrow at the pinkette.

"Sorry." The Junior Auror said, with an expression that screamed insincerity. "Guess you're stuck with me, huh?" The junior Auror smirked lightly.

Harry sighed. "I suppose."

…

Before anyone knew it two months had passed since the beginning of term and Albus had called the entire student body for an announcement. "It is time for all of you to find out the amazing opportunity Hogwarts has found itself with. We are hosting the Triwizard tournament and competing with two other of the best Wizarding schools in Europe." The students whispered amongst themselves at the news they had been patiently waiting for. "It holds three perilous tasks that three Champions, chosen by an impartial judge, will face. Even the most experienced wizards would find the tasks extremely difficult, that is why only those who reach Majority can participate." Sixth seventh of the school ġrȯȧnėd in disappointment and shouts of anger could be heard. "I know, we all have a thirst for glory but it is for your safety. I expect all of you to treat our guests with the utmost respect. I would like to introduce the Head of the Department of International Magical Cooperation who will oversee the Triwizard tournament; Bethany Gordon." A woman entered the Great Hall, she was small with dark brown skin and honey brown eyes, her dark hair tied into a braid.

She waved at the student body with a strain smile before sitting down. "Now finally let us welcome the lovely ladies of Beauxbatons Academy of Magic and their Headmistress Olympe Maxime!" The double doors opened and a small army of girls standing straight with perfect smiles marched to the front of the Hall.

They all wore pale blue dresses with small capes around their shoulders and ribbons tied at their necks along with bowler hats. Their Headmistress, a half giant with dark brown hair styled in a bob cut with dark brown eyes that almost looked black and wore a dark red robe.

They made a small performance, bowing to the Hogwarts students before standing at attention while Olympe greeted Albus like old friends.

"And now for our friends from the North, please greet the proud sons of Durmstrang Institute and their Headmaster, Igor Krakaroff!" A dozen or so men wearing brown military-like uniforms marched banging staff on the ground in a harsh rhyme. Their headmaster, a tall, broad shoulder man standing over all his students with dark hair and a goatee, wearing a white cloak, marching quietly in the back.

The boys soon folded into a group while the two Headmasters hugged in greeting. "Now students let us give these two schools a Hogwarts greeting!" The students body along with the staff stood up and began singing their anthem.

Harry, surprising most of the school, joined in with a slight smile, singing with pride, prompting even some of the more reluctant students to sing along.

"Now, for our impartial Judge." Hogwarts caretaker stepped forward carrying a large, jewel encrusted ċhėst and set it down in front of Albus's feet. 

The oldest man in the room tapped the ċhėst three times and the lid creaked open, as ancient wizard reached inside the case he pulled the object out, revealing a large wooden cup which he set against the ground that lit with blue flames, it tapped the edge with his wand and a moment later he grew to his size.

"The Champions will be selected by the Goblet of Fire. Anybody at or over the age of seventeen wishing to submit themselves as a Champion must write their name and school clearly on a piece of parchment before dropping it in the flames. You have twenty four hours to decide and during the Halloween feast the Goblet will return three names that it has decided is the most worthy to represent their schools. The Goblet will be freely accessible in the Entrance Hall for any who wish to compete." Albus gave a grin to everyone. "Now if Professor Potter would be so kind as to help me." 

Harry rolled his eyes as he stood up from his seat, drowning his cup of Pumpkin juice and walked around the table, ignoring the gobsmacked stares of the new arrivals and the giggling of his students before standing ċhėst to shoulder with Albus.

The ravenette flicked his right wrist and started writing Latin Runes in the air in the shape of a circle and directed it around the cup, Albus simply flicked his wand and a bright circle layered itself over Harry's Runes. "Show off." The emerald eyed teen muttered to the man who simply smiled before addressing the Great Hall.

"For those of you wondering, Professor Potter has created a bounded line to stop any with ill intent from crossing, such as those who wish to enter someone else's name instead of their own, while I created an age line, stopping anyone below the age of seventeen from crossing." The Headmaster of Hogwarts explained. " Now let's eat."

…

Fleur Delacour, a seventh year student of Beauxbatons, a girl with blonde, almost silvery hair and deep sea blue eyes, her skin was pale, almost if she tried her hardest not to be in the sun. She stood at five foot and seven inches, her frame was petite like a ballerina and her eyes kept being drawn to the child sitting amongst the ȧduŀts as if he was an equal.

"I see Professor Potter caught your eye." A Ravenclaw student in her fifth year with average looks spoke with a chuckle.

"I.. yees. I do not understand, why ez that leetle boy sitting up there? Is he really a Professor?" She asked some of her classmates, paying rapt attention.

"Yep! Don't let his appearance fool you, he was actually in some sort of accident and turned back into a fourteen year old." Fleur felt a little relieved at that, her Mama always told her the English were strange but she felt this was a step too far. "He's one of the best teachers in the school, and one of the kindest. Don't let his grumpy face scare you." Fleur looked towards the cold face of the supposed man trapped in a teenager's body and flinched slightly as his eyes landed on hers.

"Yeah, he looks mean doesn't he?" A male student asked with an empty voice as he stared at her with a intense look filled with ŀust, she was little surprised he could still speak given her nature as a Veela, semi human magical creatures who had an innate charm that bewitched straight male wizards, lesbian witches or Bi witches or wizards.

While she was only a quarter Veela her charm was still powerful enough for most men to become, well, complete idiots around her. "But like Alex says, he's actually really kind, he acts aloof but if you're in trouble or need help with anything, he'll drop everything." Most of the table within earshot nodded in agreement.

"He's also stupid powerful." Another boy snorted with a hint of jealousy and again the table nodded.

"How perwerful ez 'e?" Fleur asked with curiosity.

"Some of us think he's as powerful as Headmaster Dumbledore." Another girl answered, surprising the foreign students.

"Rieally?" One of Fleur's friends asked with shock. "What 'bout the others students?" 

"More powerful than Dumbledore." Almost a quarter of the table nodded leaving the Beauxbatons students flabbergasted.

"So, its 'ither, just as perwerful or more perwerful than ze 'reatest wizard in the world?" Another French girl asked with disbelief, getting nods from the Ravenclaw students.

Fleur's eyes were drawn back to Harry's but he was no longer looking at her.

...

The Defense Professor didn't care for the Triwizard tournament, more than just for obvious reasons.

Like he already won it in one of the worst ways possible and the memory forever tainted his soul. 

But honestly the whole thing was stupid to Harry, especially letting school children, even children who weren't technically children anyone, compete. He never understood why his fourteen year old self ever dreamed of participating in it after his first, second, and third year.

Didn't he have enough danger in his fuċkɨnġ life! 'Calm down Potter, you gotta give yourself more credit, sure I wanted to be Champion but It was only for a moment in a flight of fantasy of glory earned only by me, not by my mother. If only that fantasy remained that way, fuċkɨnġ Crouch Jr putting my name in the forsaken Goblet.' The ravenette growled softly at his last thought. "Fucking Voldemort." he heard a a thump and saw Nymphadora with a embrassed blush as she sat on her buŧŧ.

"You know the fear of the name increases the fear of the thing itself." He spoke and the junior Auror rolled her eyes as she stood up and turned on the lights.

"You sound like the Headmaster." Harry smiled at her words and shrugged, turning his chair to face her and leaned back.

"There are worse things to be like." He replied, the smile falling from his face.

"You don't smile a lot, you know that." Nymphadora told the boy as she sat on the edge of his desk. 

"I have, what you youngsters call, resting Bitch face." Harry said with a straight face and the pinkette let out a startled laugh that became more pronounced as she looked at his unemotional face.

"Young-" the woman tried to contain her chuckles. "Youngsters? How old are you?!"

"Twenty one."he said easily and Nymphadora smiled with triumph. "What?"

"I'm cracking your shell!~" the Metamorphmagus sang. "Two weeks ago you wouldn't have answered." Harry raised an eyebrow.

"You know I told the staff my actual age the moment they questioned me." The law enforcement officer pouted. "All you had to do was ask." Nymphadora scoffed.

"Yeah, right! You have no idea how scary your glare can be! They're worse than Professor McGonagall's!" Harry cracked a smile and Nymphadora whooped in accomplishment.

"What are you doing?" The fourteen year old questioned.

"Making sure you don't brood, you do that alot." Harry ġrȯȧnėd at the woman who grinned at the act.

"I don't brood!" He exclaimed, his voice filled with exhaustion and a hint of embarrassment.

"Yeah you do! Like all the time! I refuse to let a friend sit in the dark and brood." She shot back, kicking her legs slightly.

"We're not friends."

"Yes we are."

"We don't even use each other's first names."

"Call me Nymphadora and I'll kick your ȧss." Harry raised an eyebrow and the woman pouted. "I'll try to kick your ȧss and then annoy you all day." The teen gave a dry chuckle.

"My point still stands." 

"Then can I call you Harry?" She questioned with hope.

"Can I call you Nymph-" his mouth was covered by her two hands.

"No!" She exclaimed loudly before punching his shoulder when seeing the mirth in his eyes.

...

Harry reluctantly came to the Halloween feast but saw that neither his mother or father was present. After most of the students Albus stood up and walked to the open area, "Let us begin the Champion selection!"  The Hogwarts headmaster waved his wand twice and the double doors opened with the Goblet of Fire flying over the student body's head, before it rested in between Albus and the students. A second later he clenched his hand towards the light sources, almost extinguishing them, giving the Great Hall, and the event, a mysterious edge. The ancient man laid his lands against the cup before taking a step back, a moment later the blue fire turned red and a piece of paper flew out which the man caught.

"The Durmstrang Champion is Victor Krum!" Loud cheering from the Northern school erupted and the man, large shoulders and a buzz haircut with a goatee stood up and walked over to Albus who directed him towards a side room of the Great Hall.

The Goblet fire turned red again and with skilled hands the paper was graded in Albus's hands once more, "The Beauxbatons Champion is Fleur Delacour!" The woman with beauty unlike any other stood up and smiled brightly, her school clapping with excitement, she quickly walked over to the Hogwarts headmaster who congratulated her and showed her to the room where Victor was.

The wooden cup fire turned red for a third and finally time and the paper was quickly grabbed. "The Hogwarts champion is Cedric Diggory!"  The Hall roared with claps while a tall, dark brown haired Hufflepuff seventh year stood up with a large smile and walked over to his Headmaster who gave him a pat on the shoulder and directed him to room with the other two Champions.

As Albus was giving final words, Harry's eyes never left the Goblet of Fire that was still lit with a cool blue fire. It wasn't till students and teachers stood up to leave did the ravenette let a sigh of relief exit his body.

'Glad I don't have to do that a second time.'

…

It was midnight, Halloween had passed and it was now November first. Everyone was most likely asleep or trying to fall asleep, except for Harry. 

The teen was hardly ever asleep, too much trauma, too many thoughts and so many plans for the future.

But also because it had been one month since he began his aging potion, the sky was clear, the moon was at its highest peak and he was bathed in its light at the lake he and his Godfather almost died by Dementors kisses in his third year. The potion he had made was already in a vial that had already absorbed his hair and the Mandrake leaf he had been carrying for a month in his mouth. "Goodbye fourteen hello twenty one." Harry muttered and drowned the potion down his throat and waited.

For twenty minutes, he waited. "Well fuċk." Harry stood up and sighed heavily but as the twenty one minute passed he felt his body was on fire. "AGH!"  The teen dropped to his knees and felt every one of his bones grow and his muscles stretch. His shoulder length hair now reached the middle of his back and his face grew a large, bushy beard that stopped at the middle of his ċhėst.

By the time the blistering heat and pain stopped and he stood up his transfigured clothes were ruined and he stood over six foot. "Yes!" Harry exclaimed, his voice deep and smooth with only hints of the boy he used to be. 'Now time to get some proper fuċkɨnġ clothes and glasses. I'm tired of constantly transfiguring rocks every single day.'  Harry thought. "Thank God, Gringotts is open twenty four seven and Muggles don't know when to go to sleep." Harry waved his wand over his body, his clothes instantly fixed themselves and refitted his body.

He then bent down at his wand holster he took off when he got here and quickly resized it before strapping it on his right forearm. 

Harry then summoned his broom and as it arrived a minute later, he quickly hopped on and flew past the Anti-Apparition charm.

The moment he did not even a crack was heard and Harry Potter left Hogwarts.

…

James found himself a little worried, despite how little progress was made in their relationship the brunette felt a lump in his throat when the man trapped in a boy's body wasn't sitting next to his wife and childhood bully yet. 

'He's always so punctual.' James thought he could see the same fear in his wife's eyes.

As breakfast ticked by, the door behind the head table opened and James' jaw almost dropped.

A man, who had the same lightning bolt scar on his face as his son, who stood almost five inches taller than James himself, walked out. The man's hair was short and slicked back, he had a full, clean beard and round glasses opposed to James square ones.

As he walked over to his son's seat, James took a closer look at the man's clothes, it matched Harry's style. A tight black dress shirt folded at his elbow and tucked into dark green slacks. His son's wand holster wrapped against the man's right forearm.

The only thing James could do was smile, 'So this what you really look like, huh? Merlin, I can bȧrėly see myself in you.' 

"James is that…" the brunette turned towards his protégé and nodded.

"That's Harry." Nymphadora looked shocked before a tiny blush overcame her features.

…

Albus silently chuckled as Harry seemingly unaware of everyone's stares, he stood and brought everyone's attention to himself. "Let's give Professor Potter a round of applause at reversing his aliment and turning back into his proper age." The Great Hall was silent for a moment but soon thunderous claps were heard.

Harry gave a slight smile and gave a small wave in thanks, he felt a small grasp on his shoulder and looked to Lily who had a few tears in her eyes. "You… you look really handsome, Harry." The man blinked before sighing.

"Thank you… Lily.." The  redheaded woman nodded with a grin.
