Harry Potter: War Mage

Harry looked across from the counterpart of his Mentor, the man who helped mold him into the person he was this very moment. "You're out of your mind." he stated with a blank tone. Albus simply smiled at the teenager, "It's just, I look fourteen. They won't respect me 'and' I have a Dark Lord to track and destroy, I wouldn't even have the time to teach those kids." the white haired wizard eyes twinkled at the boy's behind his reading glasses.

"You and I both know that Voldemort will bide his time, gather more strength and train his army, especially after their horrendous display at the World Cup. Students will be forced into the coming battle, your knowledge could one day save their lives." Harry sighed, rubbing his eyes beneath his glasses. "And as a Hogwarts employee you would be under my supervision and be able to pass the red tape and purchase a wand that won't be confiscated by the Ministry or explode every time you channel your magic."

"Merlin's beard, even in another reality you still know how to get me to do exactly what you want." Harry muttered, causing the Grand Sorcerer to chuckle as he raised his hand which the boy shook.

"I'm not going to teach like this though, would you mind if I raid your potion ingredients." Albus raised an eyebrow.

"I don't think there's a Potion to permanently age a person, Mr. Potter. '' Harry shook his head with a small smile.

"Then I'll make one." Albus smiled back and nodded.

"I ȧssume you want to set up a sleeping quarters?" Harry gave a single nod. "I'll also contact Ollivander to expect you soon for your wand, do you wish for me to explain the situation or..?"

"Oh, after the spectacle I contributed at the World Cup I'm sure the entire Wizarding World knows who I am, if not now than in a few weeks. After all, we both know how rumors spread like Fiendfyre and how some reporters always seem to be at the wrong place at the wrong time but thank you Professor." Albus chuckled and nodded, patting the green eyed wizard shoulder.

"Please call me Albus, dear boy."

...

Harry pulled his raven hair back into a ponytail and was prepared to leave the Ministry with an advance on his salary ready to have a small shopping spree. 'Thanks again Fawkes.' he thought, ready to travel back to the woods and retrieve the phoenix feather he had been given along with his potion equipment.

"Harry! Hey, wait!" James called out and the reincarnated ravenette stopped in his tracks and turned to face the much taller man who could have been his father in another life.

"Auror Potter." He greeted and James let his shoulders sag at the greeting.

"That's not a good idea, listen.. James I'm not your son no matter how much either of us may want me to be and despite my appearance the time I needed my parents is long gone." Harry spoke with a blank face and the older man's face fell. "I hope you have a good life Auror Potter, you and your family." The Boy-Who-Lived turned away from the older man and walked towards the designated Apparition zone.

A moment later he Apparated and appeared in the forest he had been hiding in, grabbing Fawkes Phoenix feather before Disappariting in the Leaky Cauldron. "Hello young man." Harry nodded in greeting.

"I need a room for the night." The hunchback bartender nodded.

...

As the next day rolled around Harry transfigured the rocks he used the previous night into clothes and exited the bar. The ravenette headed towards a wand making shop he used when he was eleven years old; Ollivanders. 

Harry entered the mysterious shop and faced an old man with a balding head, the sides colored white and bright milky blue eyes who nodded in greeting.

"Hello, Mr. Potter. Albus called me, told me to expect you soon." Harry smiled in greeting and handed him the Phoenix feather he acquired.

"If you're anything like my Ollivander then making a new wand with Fawkes feather is a dream come true." the ancient wand maker grinned ear to ear and waved him to the back.

"Well let's get to it." The much taller wizard spoke with clear excitement and Harry nodded with some amusement.

It took some time to not only match Fawkes feather to a magical wood along with his own magical signature but eventually a block of Blackthorn was chosen.

Blackthorn were matched with warriors, the greater the warrior the more loyal the magical focus would become to said Magical. 

Now Harry would have to wait six hours for Ollivander's to finish his new wand, which he used to visit The Apothecary where he left the appropriate amount of Gallons, magical money, for the woman he stole from when he directed her to back for a obscure magical plant and quickly left before she returned. After Harry visited a Trunk shop and Quality Quidditch supplies, where he bought a new Broomstick and, you guessed it, a trunk.

...

As the hours ticked by, The first Potter scion traveled back to Ollivanders and gave the ancient looking man a smile as he saw a twelve inch wand; it's handle was made thick and smooth, almost marble like, the end cap curving slightly into his hand.

The shaft was designed in an odd way, the raven colored Blackthorn wood seemed to have been split two ways and then intertwined. Overall Harry loved it.

"Here you go, Mr.Potter." The ravenette firmly gripped the magic focus and felt the core of his magic connect to the wand. 

'We're going to be great partners.'he thought and he felt the weapon almost purr in his right hand. 

"I'm glad you're enjoying my work, it was slightly more difficult than I thought it was going to be but it was truly a wonderful experience." the older wizard said with a grin.

"Do you also have a wand holster I can purchase?" The pale blue man's eye twinkled in response.

...

James could bȧrėly concentrate on the massive amount of paperwork in front of him. All he could think about was his son or a version of his son, was alive and wanted nothing to do with him or his family.

No that wasn't right, Harry 'wanted' to be part of the family but he felt it was a disservice to his actual parents who sacrificed themselves for him and maybe it was.

James wasn't sure what he would feel if Evan, Derek, or Rose were in Harry's position and started calling someone else Dad when he was the one who raised them but was that comparable? He actually raised them! Harry was an orphan since he was an infant and never experienced the love of a parent.

Was it right for them to try and give it to him? What about their Harry? Was it right for them to try and treat, what was practically a stranger, as their son? Did it do a disservice to his baby's memory?

Was... was he a bad father for wanting to get to know the person his son 'could' have been? To love him like he 'could've' loved his own Harry? 

James wiped a few tears from his face as he stared at the form laying on his desk.

'Merlin, I wonder how Lily is taking this? The kids?' he covered his face with his hands. 'They must be so confused.'  he felt a pat on his shoulder and looked up to his friend

...

Lily had spent most of the night of the World Cup and the day after crying, her son was alive or a version of him was.

Harry had suffered so much, all his life really. He never had a chance to experience a mother's love and he didn't want to out of some misguided attempt to respect his 'real' parents. 

She was his mother! She was Lily Potter! It didn't matter that she technically didn't give birth to him because at the end of the day Lily Potter née Evans was Harry James Potter's mother! 

Why didn't he understand that? 

Lily heard a knock on her bedroom door but said nothing as she continued to lay in an emotional coma.

"Mama?" Rose opened the door and seeing her usually strong mother silently crying in bed, the young thirteen year old girl climbed into bed and hugged the woman. "I love you mama." 

"I love you too, Rosie." Lily mumbled as she turned around and hugged her daughter.

"I have a letter from Hogwarts addressed to you." Rose mumbled in her mother's bosom.

...

It wasn't long after purchasing his new wand and holster that Harry Floo into the Headmasters Office. "Mr. Potter." The white haired bearded man with the crooked nose greeted.

"Caaaw!" Fawkes flew around the office and sang in greeting before landing on Harry's shoulder who scratched his chin and retrieved some mint from his brėȧst pocket and fed it to the magical creature.

"Bribing Fawkes, for good favor, I see." Albus spoke with a star in his eyes that seemed to hold the secrets to all life's mysteries 

"Seems to be working too." Harry replied as Fawkes rubbed his head against his own.

Albus chuckled at the sight and nodded. "You're the first of the Professors to arrive, feel free to explore the castle, you have full access to the library for your research along with the Potion lab." Harry gave a slight smile.

"Thank you, Albus." The headmaster gave a nod.

After leaving the Headmaster's office Harry quickly settled into his personal quarters that were connected with his office in the Defense Against the Dark Arts classroom and journeyed towards the library and searched for Aging potions.

…

Harry spent what little time he had before September first, strictly researching. He was either in his room or in the library reading.

The most common aging potion used snake skin to signify the passing of time, of outgrowing old skin, Newt Spleen to absorb the toxins from the snake skin, aged banana peel, and English Ivy leaf to absorb and redistribute the toxins of one's self.

Harry honestly has no idea what the Banana peel did and neither did the literature he read but if he learned anything it was still important.

The reason why it was standard was because you could control how much you aged by the amount you drink, other potions would either age you forward or backward by a decade or so.

What Harry found in common with all of the aging Potions is they all used Snakeskin and the ravenette knew where to find the shedded skin of one of the deadliest snakes on the planet.

Underneath the school was the corpse of a fifty foot Basilisk and all wizards knew the more ancient and powerful the ingredients were the more permanent a Potion becomes.

Of course a Basilisk was a Dark creature, he would need to purify the skin before using it, 'Fawkes could help.'

"POP!" 

"Maaster Hairy, Dumbly Door has requested you to join the Welcoming Feast." A two foot tall creature with pink skin and ravaged clothes.

The emerald eyed teen ġrȯȧnėd as closed the book and with a flick of his right wrist his wand flew into his hand, a quick swipe down his casual clothes transfigured them. His jeans became black slacks, his green shirt became a white buŧŧon up, tucked into his pants with the sleeves folded to the elbow and his tennis shoes became black leather boots.

"How do I look Mipsey?" He asked the elf who gave a thumbs up before popping away.

Harry adjusted his round glasses and began walking to the Great Hall, it took him a minute but he entered the door leading behind the High Table, where the Hogwarts Staff sat at the farthest point from the entrance of the school.

He paused as he looked towards a familiar redhead with similar green eyes to his own. Lily smiled shyly at him, the teen promptly ignored the clench of his heart.

"Mr. Potter, wonderful to see you out of your room." Albus greeted, the ravenette gave a wave ignoring the looks of disbelief from the teachers as he sat on the left side of his previous potion master and double agent to the Dark Lord, Severus Snape. A greasy black haired man, with pale, waxy skin and a sharp, hook nose who stood an inch shorter than himself, at five foot and eight inches.

"Albus wha.. what 'is' this." Severus grunted, glaring at the boy who sat next to him, wearing Muggle clothing.

"This here is Harry Potter, the new Defense Against the Dark Arts professor." The older man introduced the teen.

"Ha.." Hagrid, a twelve foot giant, mumbled, his beetle-like eyes watering at the sight of the boy who looked so much like James.

"Don't be absurd Dumbledore! Harry Potter died as an infant." Severus spoke harshly, his coal-colored eyes digging in the side of his head, the fourteen year old simply took a sip of Pumpkin juice, Lily glared at the Potions Master with pure venom causing said waxy skinned man to flinch slightly.

"Yes he did, this is a different Harry Potter, for another world." Albus smiled lightly as most of the staff jaws dropped. 

"I..what?" Severus questioned with narrowed eyes and the ravenette felt a jab in his Occlumency shields that the emerald eyed teen immediately and viscous batted away.

Severus flinched hashly and Harry continued to look at the entrance unbothered.

"Why is he the Defense professor? Isn't he.. a little young?" Aurora Sinistra, a brown skinned, slender woman with dark brown eyes who taught Astronomy.

"I'm twenty one, I just happened to be trapped in this body for a moment. An unexpected consequence of how I arrived." Harry answered easily with an unbothered tone.

Before any more questions could be answered the double doors opened and hundreds of students entered the Great Hall, some immediately noticed him, others only paid enough attention to their friends and the track to their seats.

The minutes silently rolled on as the second to seventh years seated themselves at their respected tables, soon a wave of ghosts passed through the double doors and the would-be first years walked in behind the Deputy Headmistress of Hogwarts and Transfiguration professor Minerva McGonagall, a frail looking woman with a strict pale face and grey hair mixed with streaks of brown that was hidden behind her pointed hat.

Her pale green eyes hidden behind reading glasses, which narrowed slightly as she looked towards him but her stride never faltered towards the stool with an old, withered brown witch hat laying on top stationed in front of the high table. 

Beside the entrance to the door were two  familiar people, one James Potter who tried not to awkwardly stare at his son and a pixie haired pinkette with equally bright pink eyes, who stood at five foot and eight inches with a athletic build, a heart shaped face and perfectly tanned skin.

Harry turned towards Dumbledore who sent him a small, mischievous smile, the ravenette rolled his eyes and looked forward again.

As Minerva stood beside the stool, the hat came alive and sang the typical spiel it did every year since its creation, how it was created, what it was used for, the typical traits of each House.

Harry wasn't sure if it was the same song that was sung for his fourth year but he supposed it didn't really matter.

After the Ancient magical fabric finished, the first years began to be sorted.

Harry hardly paid it any mind except when it was his brothers' turn. Surprisingly, Evan and Derek were both sorted into Hufflepuff.

The oldest man in the room stood up with an all encompassing smile. "Welcome all to another wonderful year at Hogwarts. These are dark times as Voldemort," he paused as the students almost recoiled as one. "has returned. The Ministry and I found it prudent for extra security, so they sent two of their best to help defend us, Senior Auror James Potter and Junior Auror Nymphadora Tonks. Treat them as you would treat a Professor. As always, The Forbidden Forest is Forbidden to all students and it is my great displeasure to inform you all that there will be no Quidditch Tournament this year." he paused for a moment to allow the groans of disappointment. "Instead there will be something much grander, a different kind of tournament that hasn't been seen since eleven hundred sixty-nine that two other Wizarding schools will participate in for untold glory and a thousand Gallons." The students began muttering in excitement. "I would also like to introduce you to the new Defense Against the Dark Arts Professor, Harry Potter and the New Charms Professor for first through fourth years Lily Potter."The ravenette raised a hand in greeting while Lily gave a bright smile. "I'm sure they both would like to say a few words." The fourteen year old grumbled before standing up along with his alternate universe mother.

"Hello students, I'm sure many of you are wondering why I look fourteen, what my qualifications are, where I received this nasty scar, and if I have any relations to Auror and Mrs. Potter? To answer all your questions, none of your business. I'm Professor Potter, Mr. Potter, or Sir, do not use my first name, we are not friends but I will promise to teach you to the best of my ability." The young man tried to sit back down, only for a familiar Slytherin student to stand up.

"I refuse to be taught by a teenager! My father will not stand for this tomfoolery! Don't get too cozy here, your prepubescent 'Muggleborn', you'll be out of the job soon." Draco Malfoy, a bleach blonde haired fourteen year old teen with icy blue eyed and pale skin. His father, Lucius Malfoy, a School Governor that had a major say in how Hogwarts could be run.

Some of the teachers face twisted, along with Lily's who was ready to Hex the boy along with her husband, and were about to correct the disrespectful behavior, only for Harry to quickly handle it, "The appointment of teachers are strictly up to the Headmaster Malfoy, the Board of Governors can dismiss me only if I show a mass amount of incompantace or if I show a negative moral character that can endanger the student body, which I will ȧssure you I won't. That will be ten points for talking out of turn, another forty for using 'Muggle' as an insult and sixty for threatening a teacher with 'daddy'." Draco's face burned in embarrassment and most of the hall laughed at him while most of his Slytherin glared at the pale blonde for already losing a hundred and ten points. "Anyone else?" He looked throughout the hall only to receive shaking heads.

"Great." He was about to sit when he remembered something else, "To the sixth and seventh years, the Exceeds Expectations to enter N.E.W.T classes is now void," he paused his address as about two-sevenths of the school began yelling, ȧssuming he was raising the standard. "QUITE!" Harry's voice roared across the hall silencing everyone, as the teen untensed he continued. "As I was saying, there is no minimum grade to enter Defense any longer, even if you received a Troll on your O.W.L's or your sixth year final exams, you still will be accepted into my class." The hall was silent in shock, including most of the teachers at his decision only for the sixth and seventh years to fill the silent room with applause and cheers.

As Harry sat back down, Lily felt the entire student body look at her, wondering if she had some wonderful news as well. "Hello students, as you heard I'm the Charms Professor for the lower years and I simply want to say that I have loved Charms since I was a little girl and it is my absolute pŀėȧsurė sharing that love with all of you." The green eyed woman sat down after she finished.

Albus' smile seemed to stretch at the Great Hall, "Let us feast." He said as waved his arms, all four tables filled with food along with the teachers plates.

…

Harry rubbed his eyes in tiredness, staying up all night reading more potions books, expanding his research perimeters to potions that cause transformations, such as Polyjuice and Animagus Potions which he already knew but only had loose understanding of.

He easily ignored Lily's constant chatter in his ear, Derek and Evan's wide excited smiles, Rose's shy grin and James's puppy eyes from across the room as he ate breakfast with the rest of the staff.

As breakfast ended he journey to his classroom and waited for his first batch of students to enter, Gryffindor and Slytherin third years, that contained his, alternate sister, ex lover, ex lover's sister who was suppose to be a second year, and close friend who was brutally murdered.

'Yeah…' Harry thought grimly.

"So, boys and girls, who knows what a Dementor is?"

…

His second period was fourth years containing most of his ex classmates, main bully, his second lover, and his best friends. 'I hate my life.'

"Okay, who here knows what the Unforgivables are?" He asked the room, only receiving a few hands, one from Hermione, Daphne, and Neville.

The rest of the glass stared blankly at him. "Yeah, figured." The ravenette muttered, he was about to call on Neville, knowing that unlike his Neville, this one never suffered losing his parents to the Cruciatus Curse.

…

Rose was reeling from her lesson she received from her brother, she knew she had a lot to learn from him, the memories of that awful battle stuck in her head but she had no idea he was… such a good teacher.

She remembered Uncle Mooney teaching them the year before and he really filled their noggins' with knowledge but Harry, her brother, made the class fun!

She thought he would be like Professor McGonagall or Snape, just push through the class, making everything boring or insulting them for being idiots who needed to be taught in the first place.

Harry did give off both vibes from the Welcoming feast but the ravenette attitude did a one-eighty once he talked about Dementors, the Patronus Charm that stopped the vile creatures and its variant stages.

He even casted it himself, the brown eyed teen almost had a heart attack when she saw her fathers Animagus form.

She definitely had a heart attack when it flew across the room before growing to the size of the ceiling and shrinking down to an ant. 

He even let the class ride them, of course he had to banish the tables, expand the room and then conjure about two dozen more that were the Animagus form of her Uncle Sirius and a werewolf, which he did!

Her brother was brilliant!

Astoria Greengrass, a dark brown haired third year Slytherin with dark chocolate brown eyes glared at her uppity slightly older sister, by a year, who refused to believe her about her wonderful time in Professor Potter's classroom.

"Astoria, it's just not possible for a single boy to create a fully corporeal Patronus let alone over two dozen, some ȧduŀts have trouble making just one." Daphne Greengrass, a silky blonde haired fourteen year old with unblemished pale skin, full lips and icy blue eyes that never seemed to warm, told her little sister. "I admit Professor Potter is much more knowledgeable than I initially gave him credit for but I doubt Merlin himself could do what you described."

Astoria glared hashly before smiling, which scared the older blonde slightly, the pureblood teen dashed off the table towards the high table towards said fourteen year old teacher. Tracy Davis, a honey brown haired teen girl, with almost amber eyes shook her head. "You definitely should have seen that coming." 

Daphne glared at her best friend, a glare that would give fully grown wizards a pause, before sighed and waited for her sister to come back disappointed and pouty.

"Professor Potter?" Astoria stood in front of the table looking at the boy her supposed age, who bȧrėly showed any emotion.

"Yes, Ms. Greengrass?" He continued to eat, unbothered by her presence.

'Rude but I guess when you're as powerful as he is, manners are a non issue.' "Can you create some Patronus sir? My sister doesn't believe me when I say you made them for class." She asked with a smile that she knew could make boys melt.

Of course it didn't work on Harry who raised an eyebrow. "And why is that an issue? I'll be teaching fourth years the Patronus in the next week or so, your sister will believe you then." Astoria pouted.

"She practically called me a liar Professor," she saw an eye twitch at that, 'So he doesn't like being called a liar? I can use that.' "I'm sure you wouldn't understand Professor but it really hurts that my own sister doesn't believe me," she added in a soft voice as she looked down, it was true but not to the extent she was playing up. "I want to show her that I'm no liar." She said with a resolute frown.

Harry sighed and Astoria almost pumped her fist in victory. "Fine but only if you tell me the proper incantation and wand movement." Astoria smiled with ȧssured victory, she paid attention in class, it was one of the best she ever had.

"The incantation is Expecto Patronum and the wand moment in to draw a small clockwise circle." Harry gave a raised eyebrow.

"You sure?" He asked, his tone suggesting she was wrong by Astoria nodded resolutely.

Harry gave a sigh and stood up, "You're right." He flicked his right wrist and raised his wand to the sky. "Expecto Patronum." He easily spoke and a silver stag shot out of his wand and galloped across the room, the ravenette ignored the gasps of awe.

Astoria shot Harry an unimpressed look, Harry rolled his eyes and several more Stags, Dogs, and a few Werewolves shot out of his wand joining the original Prongs as they messed with the student body as the original Marauders would. "Thank you Professor!" She exclaimed with a wide smile, the brunette skipped to the Slytherin table enjoying her sister's shocked face.

Harry sat back down as he sheathed his magical weapon and continued to eat, ignoring the gobsmacked stares of his colleagues.

"You… you…" Lily couldn't speak, what she just saw was impossible, she never heard of a person make more than one Patronus.

Several moments later Astoria came back with a furious frown and Harry almost ġrȯȧnėd. "Professor~" she whɨnėd at the teen. "Daphne said she doesn't believe that I actually rode one! She says it's impossible and against all the laws of magic." Harry telepathically commanded the closest Patronus to take the third year away and a Padfoot flew underneath the pureblood girl and sped her back to her seat.

"I see you as much of a glory hound as your pompous father.." Severus sneered at the boy who shot him an unimpressed look.
