This is a Harry Potter & Familiar of Zero Cross Over Fanfiction Only.

My lessons in the school were in a word, a waste of time, the only time that was not wasted was when I was teaching Louise all the theory I could about the magic that was not elemental in nature. I can say many things about her, but lack of dedication to my lessons was not one of them. I began to teach her as if she was the first year in Hogwarts.

I mean I began teaching exactly the same lessons, I taught her a class on charms one day, a class on transfiguration on the next, hexes, curses, and other offensive magic when I saw she could handle the first two spells I taught her, and potions because she needs a well-rounded education, and because it appears this universe has some crazy ideas about the different kinds of potions.

I personally hated the notion of a love potion and made sure to teach my student ethics first and foremost, especially about ethical thinking regarding the use and brewing of potions. Little did I know that in fact, I was not alone in my hatred of such potions, the very kingdom that the school was in made a law that making such potion, and using it was heavily punished.

"Well done Louise, that is the levitation charm. This charm is useful to lift items off any surface, even water, right now you can only lift a feather, but with enough concentration and practice, well you will be able to lift bigger and heavier things. I am not joking that this spell can be used to save the lives of people in need. A person falling from great heights or a person that is drowning can be saved by this charm."

I saw that she was still having trouble with the transfiguration and the lock bind hex. "Transfiguration is one of the most dangerous and most demanding forms of magic that I will teach you, there simply is no room for taking it easy, this is serious business, and if done incorrectly it could even kill you. You will continue to use the spell I taught you till you managed to turn that piece of wood into a needle."

She was truly getting frustrated with this and she stopped practicing for a second before she began to walk towards me with a nasty expression on her face. "Why do I need to know how to change one thing into another? What is the use of being able to turn a piece of wood no bigger than a toothpick into a needle? How about a little demonstration? Or it is that you know the talk but can't do the walk?"

I could do her needle transfiguration with my eyes closed, but I better maker her see we are not in the same level when it came to magic, I better make sure my student understand why I am her teacher and she is my student and earned her respect.

I picked one of the toothpicks and with a slight movement of my hand the toothpick became a needle, another movement of my hand the needle became a metal bar, the metal bar under my command began to change into a metal serpent, Louise was not smiling when she saw the metallic snake slither towards her.

She tired to cause the serpent to float away from her, but she could still not handle the spell well enough to lift something as heavy as the snake. I ordered the snake to wrap around her neck, she truly was looking scared as I gave my order in the language of snakes. When the snake bites her own tail, and with a snap of my fingers the snake became a metallic necklace, and as she touched it, the necklace became the toothpick in her hand.

"From wood to metal, from metal to living, from living into the inanimate, and back to wood again. All in matter minutes, your friend is injured while walking through the nearby forest, you can't carry your friend, but with the branch of magic I am teaching you, you don't have to. You should be able to make a horse and carriage from a large rock and a couple of field mice. You want to cook something but your friend did not bring a pan? Make one."

Louise kept looking at me and finally, she understood what I was saying, "Or I could make a gift for my best friend in case I wanted to make something special for her birthday. Like the necklace, you made a few moments ago. Sad that it turned back into this toothpick, it was a rather nice necklace."

That is when I looked at her and smiled, "If you liked the way the necklace looked by the time your training in this branch of magic is over, you will be able to make that, and a pair of bracelets and earrings to match."

I began teaching her the spell and sure she had a tough time, but by the end of the first lesson, the did manage to make a needle, some of the ends of it was a little like the toothpick but she made good progress, McGonagall would be proud of my lesson.

As time went by she got closer to her familiar and she also got better at the spells I taught her, she could cast charms to the level of her current year, transfiguration and a few hexes, curse she had a bit of trouble because she surprisingly enough did not have the intent on causing actual harm on the targets I had transfigured for her.

That was an issue until I made a mannequin that looked like me, and that proved to be a very good idea, she had no problem at all cursing that mannequin into pieces. If I was an ordinary guy I would worry about my safety, my student could not use a spell that caused harm on a snake that I made by transfiguring a rope, but the mannequin, she can burn, explode, crush, or even cut in half with no problem at all.

The lessons I was learning in the classes they taught were as interesting as a history lecture from Professor Binns, and in case I have to explain, Professor Binns taught History back in my old school, he simply took a nap in the teacher's lounge one day and kicked the bucket, he's got simply got up from where he was taking his nap and taught the class as nothing happened, this guy could put anyone to sleep, a great cure for insomnia though.

The lessons became my unofficial nap time, as I spent so much time teaching Louis, I needed the extra sleep, some of the teachers would throw at me a piece of chalk and try asking me to do a class task, the teachers that threw me an apple were the ones I really felt any gratitude towards, I really found the snack helpful.

My lessons were progressing rather well, and thanks to the mannequin approach my student caught up to her current year level, it only took her two months, which in my honest opinion it was rather amazing, couldn't help but to feel pride in the academic accomplishments of my student. Her familiar and she became so close, it was almost like they were friends all their lives.

In the end of the third month we were told that since the Familiars had plenty of time to get used to being with their masters, and their masters knew the familiars better, a little show and tell sort of festival was going to happen, the festival was to showcase the talents of the familiar the students summoned.

"Honestly, this is not the way to treat a familiar. They should be grateful that they have someone that is willing to help them, be their friends, and constant emotional support, it is not proper to simply treat them as pets for bragging rights for crying out loud."

Considering that she once was much like the people she was complaining about, I could not help but lose control of my emotions, a tear began to roll down my eye, to see my student understand what I taught her was simply so wonderful that I could not help it, I simply was overwhelmed with this feeling of joy.

"Why are you crying, sir? Did I say something that you found offensive?" I could not help but to smile as I heard my student say this, not long ago she was this boastful, egocentric little tomboy, now she treats me with such respect, and I still have many things to teach her. I wonder if the professors that taught at Hogwarts ever felt like this.

"No, my student, you said nothing that is offensive, I simply am happy that you have learned the things I was teaching you, you make me very proud my student, indeed, after they get done with their show and tell show, I think a reward is in order, I guess I will give you a treat and show you how to change forms."

She looked at me with a bit of confusion, guess I never taught her what an animagus is. "Louis, mages like me and soon enough you, can take the form of an animal, an animal that is similar to the mage that attempts this feat. Those that can take an animal form are called animagus, one of my teachers could actually transform into the form of a tabby, I will need to prepare a potion for you to discover your form, but at the end of the show and tell I shall show you my animal form."

As I began to eat dinner, I looked at my friend and familiar Morgana, who was eating something right next to me, "Don't worry Morgana, they clearly said that the festival is to show the newly summoned familiars talents, that should not apply to us. I had the joy of your company for years, so why do you look so worried?"

She finished eating and looked at me with a look of pity, I never seen her looking at me like that, "You might say so, Harry, you might even think so, but trust me, sometimes the best-laid plans, the most believed notions fail to meet the person's expectations, you might end up having to participate."

"Now why don't we enjoy a night stroll, to simply enjoy the night time air?" I knew why she said that the reason was that she was going to tell me something, something she did not want anyone to even attempt to listen, as some clearly are trying to do. "Sure, let's go."

I got up and she went inside the mark on my shoulder, we walked towards the exit, and that is when I saw someone I was not expecting, Guiche actually flirting with another girl, this time a brunette, a year younger than her or at least that is the impression I was getting.

"You know Cathy there is nothing hidden in my feeling for you." Here I was thinking that the pickup lines Fleur told me she endured were bad and after hearing this from him, they were at least not as corny as what Guiche said.

I decided to walk near them, "Miss a young lady such as yourself should be more careful with this one, I have seen him be rather close to a blonde lady in his year, and tried to flirt with three other ladies in different years, Guiche here styles himself the schools, Casanova, so I suggest you do a quick analysis of anything he offers you."

As I began to walk away I saw the girl I know he is currently dating the very same cheating moron, I looked at her, she clearly was looking for someone, and I think I know who it is. "Excuse me, Ms, Montmorency, I do believe that is your name, you already know who I am, if you are looking for your boyfriend, I believe you will find him getting yelled at by a young lady with brunette hair color, by the fountain by the entrance to the dorms."

I know I should not really bother to do this, that this is really a private manner, but then again I always had a soft spot when it came to defending the dignity of the fair sex. Fleur simply called it my knight in shining armor complex, I guess even here I simply hate to see women being abused like that, playing with their emotions for fun, how low can a guy go?

Back when Fleur was with me, I often talked with her how I would deal with fools that dared to do such things with our potential daughters, it always ended the same way no matter the discussion, one fool dead, my daughter safe and the only difference was how the fool died.

Sure enough after a few minutes he had two young ladies screaming at him such things that made even me blush, on my way to the dorm I found three more ladies that I know had been flirting with him, so I did the only honest thing, gave each a friendly piece of advice and directed them towards where Guiche was getting yelled at.

I finally made it back to my room and I simply could not stop smiling, today was a good day after all, I made a pervert suffer, my student is learning very well, in fact, if this continues I can even slow down the rate she is learning at, allowing her to take it easier with my lessons, since she is pretty much has caught up with my plan for her studies.

Well seeing that she no longer needs to be taught at such a faster speed, gave me plenty of chances to try and experiment a little, since now I had some free time, Colbert was nice enough to let me use the instruments in his lab, and with a little work I had a minor forge constructed, the idea was that Colbert needed it to make new instruments he could use or repair things for the school. Metallurgy research was the official reason that was written into the school records.

It was not a lie, I did plenty of research trying to combine their equivalent of iron and copper, the main reason is as a soldier I feel quite frankly naked without a weapon, my alone time was primarily focused on the things I no longer had, weapons and armor I could use, it simply not good not being able to defend myself if for some ungodly reason someone finds a way to negate all magic in a battlefield.

The first thing I made was a simple press, it was simply to allow me to assemble the ammunition, the next best thing is I had to mix something these people never even knew of, I am not kidding these people never heard of gunpowder. I will never be able to forget the things father taught me, and I find myself being very grateful to him.

I made every component needed, I made a light durable blend of metals, that allowed me to pretty much make a bullet with a crystal tip, the tip would be the thing I place my spells in and in doing so, I do something they never imagined, I could fire a single shot to penetrate armor, and at the same time blast the inside of my target with a spell.

I felt that I should keep the construction of my weapon simple, the less complicated the better reliability, so I made a revolver, a simple six-shot revolver, mine was made to be quite durable, and thanks to magic I also made it possible to only work for me, and expel empty casings and teleport ammo to replace it with a simple metal command.

I made enough ammo that if I really wanted to, I could take on a squad of enemies and it is nice to know that this world does not have the inconvenient rules and regulations my original world had, nothing stopping me from using excessive force here, nope, nothing at all. "So Mr. Potter what do you call this thing that you been working on if you don't mind me asking."

I looked at him and smiled, "I don't mind at all Professor Colbert, why this is my new sidearm, this is the effort to combine magical and non-magical means to the field of practical combat, I call this beauty Gehenna, because the people that go up against this, will feel like they are in hell."

"Harry, there is no need for such a thing in this world, you know we are pretty safe in the Kingdom of Tristain," I told him that it never hurts to be prepared, this little creation of mine could end up saving the kingdom, after all, if someone I held dear once taught me, peace is a lie.
