After leaving the Hogwart Express, Harry appeared at Hogwarts. The first thing he did was change his height to make himself taller and then changed his hair to blond and his eyes blue.

After doing that Harry waved his hand and the conversation he had with Daphne and Tracy began to be played in every room at Hogwart's as well as in Hagrid's cabin and in the village of Hogmeade which was located near Hogwarts. It was also heard in the Forbidden Forrest.

As the conversation began to play, Harry began to walk around the grounds before finding a nice spot to sit down and he pulled out his book and began to read.

Once the conversation ended, Harry stood up and walked into Hogwart's and after pausing a moment began to move toward where the staff of Hogwarts was located which turned out to be the Headmaster's office.

When Harry reached the gargoyle statue that guarded the Headmaster office he waved his hand and the gargoyle moved aside and Harry began to walk up the steps.

As he reached the top of the steps the door opened and Harry saw all the staff looking in his direction and several members had thier wands out.

Harry rolled his eyes and said "Wow, what a warm welcome. Do you treat everyone this way."

Dumbledore said "Who are you and why are you here."

Harry said "I go by the name Ren. I made sure everyone in Hogwarts, Hogmeade, and the Forbidden Forrest heard the conversation I had with those two girls earlier so you can guess why I am here. I'm here to teach Magical Leveling and Oep's."

Dumbledore said "I'm afraid that's not possible because I do not approve of you being here."

Harry smiled and said "Well before you curse me, perhaps you should read something I have for you. Your old friend Nicholas Flamell helped me right it up."

At this several people got a confused look on thier and Harry motioned toward his pocket and said "May I bring it out without being attacked."

Dumbledore frowned and said "Very well."

Harry nods and reaches into his pocket and pulled out a folder and the folder floated out of his hand toward Dumbledore's desk causing several gasp.

Professor Flitwick said "Wandless magic."

Harry looked at him and said "Everyone who knows about Oep's is able to learn to do wandless magic easily. Truth is the only reason wands were used in the first place is because Nobles from Europe needed magical numbers to help defeat invaders and so instead of teaching true magic that could take years to learn and instead had uneducated subjects use a wand to learn a few battle easy to use curses for battle. In fact, the Nobles gave the Founders of Hogwarts this land and the money to get started to help train what was basically cannon fodder to help create an army for themselves without having to do the work of teaching thier future soldiers themselves. It was easier to just hire them once they had some education behind them."

Dumbledore who had started to read the folder while listening looked up in shock at Harry and said in a demanding tone "What is this."

Harry looked at Dumbledore and said "The last page is a magical binding contract that you are going to sign that allows to me begin teaching. The other pages like the contract was written by Nicholas Flamell who is extremely PISSED at you right now. He's so pissed at you right now after he found out what you did he's ready to use the contract you signed when you began to learn alchemy from him in order to kill you. You have until the students arrive to sign the contract. Once you do, a copy will appear where Nicholas is. If that copy doesn't arrive by the time the students get here...well, you'll die. You've spent years giving half truth and lies in order to manipulate others. It's time to pay the piper."

McGonagall asked "What's going on Albus."

Harry ignored Dumbledore and said "The stone you are guarding on the third floor is a decoy created as a sign of trust between the Flamell's and Dumbledore. Dumbledore thought it was a real stone but it was just a test to make sure he could be trusted which he has proven he can't be. Dumbledore has been able to track some Dark Lord or Lady and has decided to set a trap for this person here at Hogwart's knowingly putting the lives of the student's and staff in danger. He decided to use the stone he thought was the real Philosopher stone as bait for the trap. Since Dumbledore suspect that the Dark person he has tracked is Voldemort since the body was never found he decided to set the trap the same year Harry Potter was suppose to show up thinking if it was Voldemort that the thought of not only getting the stone but finishing Harry Potter would be to much of a bait for Voldemort to ignore. That's one of the reasons he sent me here."

Harry looked around the room seeing the shocked and a few angry faces and he continued "I've been sent to help protect the students if this Dark Lord or Lady shows up since Dumbledore has already proven over and over he's not able to defeat Voldemort in combat with how many times Voldemort left battles leaving injured and dead enemies. Dumbledore being order and most likely slower since he spends so much time playing politics will have an even harder time."

Harry sighed and said "Nicholas also wants me to go to different schools of magic and teach for 10 years, long enough to get a first year student trained up to take thier Owl's, Newt's, and then apprentice under me for at least a year before leaving my apprentice to take over teaching my subject before I go to another school and begin teaching them doing the same thing. I was originally going to teach at another school until Nicholas found out about Dumbledore's latest act of stupidity."

Dumbledore said "THAT'S ENOUGH."

Harry said "I couldn't agree more. I don't like the fact I am having to clean up your messes Albus Dumbledore. I already having to deal with Gallert for you."

Dumbledore's eyes widen as he paled hearing this while everyone else in the room looked confused.

McGonagall asked "What do you mean."

Harry snorts and said "Dumbledore did not kill Gallert. He locked him up. Do you really think a prison built by Gallert Grindelwald himself would be able to hold Gallert. For years Gallert has had a ward setup that allowed him to know when Dumbledore here showed up to check on him. He would then use a timeturner, go back a few hours, change cloths, put on a few charms to make himself look like a prisoner who has not seen the Sun in years and wait for Dumbledore's visit to be over before leaving again to continue whatever he was doing before being interrupted. With Dumbledore telling everyone Gallert was taken care of they had no idea what Gallert was up to...would you all like to see what Gallert's been doing all these years thanks to Dumbledore's mistake. Watch."

Harry waved his hand and a portal appeared and everyone could see countless zombies walking around several ruined looking buildings.

Harry closed the portal and said "Grindelwald had his own version of the Department of Mysteries called Group 935. Using thier secret research they have created an army with billions of zombies just waiting for the right moment to unleash them on the world. One of the things I am going to be teaching students to do is how to defend themselves against the zombie curse."

Severus Snape said "Just use fire on them."

Harry looked at Snape and said "A zombie and an Inferi are two very different things Severus Snape. An inferi is just a reanimated corspe where a zombie was someone who started out alive and was hit by the zombie curse either by a wand or by being infected by an untreated zombie bite. If the curse over powers a persons magic with 72 hours of being bit then they will become a zombie. A zombie, unlike an inferi, also has a soul. The curse needs it's victims soul to keep the curse active inside the zombies body. Unless you completely burn the body to ash releasing the soul, a zombies body will restore itself enough to keep attacking over time. No, you have to actually destroy the curse or destroy the body completely to stop a zombie. I will teach my students how to treat the curse of a zombie bite so they don't turn into a zombie if they are bit."

Professor Sprout asked "How could Grindelwald be able to create so many zombies without anyone finding out."

Harry said "Time magic. Gallert's people would create a ward around a location that would trap the location in a time bubble. They would then unleash the zombies on the location turning everyone in the bubble into zombie. Once they were done they would send the zombies back to thier base before undoing the ward that would reset everything back to how it was before the time bubble was activated. Basically think of them making a copy of everyone where there is a regular person and then a zombie copy of them. They have built this army up over years. Just like house elves do to create the food they feed the students and staff. They create one perfect dish and use magic to duplicate it. Ever since before Grindelwald was defeated this army has been getting built waiting for the right moment to be released. I've been hunting down every member of Group 935 I have been able to. Some members have broken off and formed joined other groups increasing the danger they present."

Dumbledore asked "How can you be sure Grindelwald is involved."

Harry motioned toward his pocket and said "May I present my evidence."

Dumbledore nods and Harry pulled out a metal box about the size of a shoe box and Harry floated it toward Dumbledore's desk and Harry said "Inside that box you will find the severed hand of Gallert Grindelwald. Any identification spell will be able to confirm it. I cut it off Gallert myself less then a week ago." shocking everyone in the room.

Dumbledore opened the box and found a severed hand and he quickly cast several identification spells before he slumped down and said "It does belong to Gallert."

Harry said "So how many dark lords or ladies does that mean are running around killing and torturing people and risking the statue of secrecy, not counting thier followers of course."

Professor Vector frowned and said "Your enjoying this, aren't you."

Harry glanced at her and said "Truthfully, no I'm not. I had planned to sit back at a different school teaching and enjoy the show as the public began destroying Dumbledore as he told lie after lie trying to cover up the truth while looking for me as they tore down the house of lies he's created for what he calls the greater good."

At this everyone in the room got a confused look on their face and Dumbledore asked "Why would I look for you when I've never met you before."

Harry smirked and said "Oh, we met years ago when you abandon me on a muggle doorstep in the middle of the night before you created a fictional superhero you for the magical world to believe in so that when you arranged my death with the trap on the third floor."

At this several eyes widen and McGonagall said "Your Harry Potter."

Harry glared at her and said "Harry Potter no longer exist. I've magically changed my name before I passed my Owl's and Newt's. I am Revan Edward Noctis or Ren for short. Since the Sorting hat which is connected to Hogwarts registry has heard my claim and has magically verified it, Harry Potter has been removed from it's register and with it the final link to Harry Potter has been destroyed. Am I right hat."

The Sorting hat shifted and said "You are indeed correct Professor Ren. Hogwart's has accepted your position as a Professor of Magical Leveling and Oep's. It has been over 700 years since we had a professor for that course."

That made everyone in the room blink and the now identified Ren said "Really. When Nicholas told me the course name I would be teaching I had thought he just made it up."

The Sorting hat said "No, he was in fact one of the last students who had taken the course and that was only as a first year."

Ren said "That does not surprise me considering what I know about him. I almost killed him when he surprised me while I was hunting some of the members of group 935."

Flitwick asked "Why were you hunting this group 935."

Ren looked at him and said "My mother Lily was adopted by the Evans family. My grandmothers real name was Samantha Maxis. She was the daughter of Edward Maxis, a researcher who worked for group 935 before he found out what the results of his research was really for at which point he began to work against them. Samantha has spent her life trying to stop them which is why she gave birth to my mother she hid her with the Evans who adopted my mother. I haven't seen her since 84 when one of the other groups I mentioned tried to release the zombies on the world. She might still be alive some where...or some when. You can't be sure when time travel is involved. I've been hunting them after they tried to kidnap me and experiment on me after they found out my connection to my grandmother...BIG mistake."

Ren looked around the room before looking at Dumbledore and said "ANYWAYS...The Sorting hat agreed to me being a teacher but that does not save you from Nicholas fury...Nick's...Fury...hahahaha."

Professor Snape asked "What's so funny." in a sneering tone.

Ren who was laughing slowly calmed down and said "It's a joke, you either get it, or you don't. It's something you can't explain...Now as I was saying, if you don't Nick to kill you with that contract you signed years ago, you better think about signing the contract I gave you. I got to find a classroom to setup in and prepare my quarters. I figure you got the elves already getting something set up for me, hat."

The Sorting hat said "That is correct. A house elf will show you to your classroom and your private quarters."

Ren nods and looked around the room and said "Do not call me Harry Potter. I am Ren. If people ask about Harry Potter, tell them he has taken private education elsewhere and wanted to start a new life away from the painful memories this country brings. Tell them his location is hidden by wards that prevent him from being located for his own safety after one to many attempts on his life by his families enemies. Got it."

Dumbledore said "I do not agree."

Ren glared at him a moment before starting to mutter something in a language nobody could understand and then there was a flash of light in the room and Ren smirked and said "I figured you would try to do something to screw me Dumbledore so I have just put a taboo on the information about who and where Harry Potter is. Anyone attempting to give that information will summon a pack of zombie dogs who were specially created to hunt down and rip the souls of the enemy they are hunting. Break that taboo and there is no where you can hide from them. Even if you were stupid enough to split your soul to try and save yourself, they will hunt each piece down and destroy them. My grandmother's pet dog Fluffy was one of the first zombies created by group 935 but it remained loyal to her even after becoming a zombie because it was her familiar and since she was pregnant when she was experimented on, those dogs are loyal to her and her family."

Ren smirked and said "And since I know you won't believe me."

Ren waved his hand and a chair turned into a pig and Ren said with glowing eyes "FETCH ME HIS SOUL."

Suddenly a demonic sounding howl was heard before there was a flash of light and a zombie dog appeared in the room and quickly attacked the pig killing it.

The dog after killing the pig walked over to Ren and sat down beside him before growling at those in the room and Ren said "Good boy."

The dog bark before disappearing in another flash of light.

Ren smirked and said "Did I forget to mention that every dog they have bit that became a zombie became members of thier pack and have the same loyalty to my family. Thier is no ward that can protect you from them. They can appear inside any ward. Think about that before you break my taboo."

Ren turned and walked out of the room and found a house elf waiting for him.

As he followed the elf Ren thought "What's funny though is that almost everything I said was true from a certain point of view. Lily really was Samantha's daughter. Turns out Nicholas and his wife are really Guardians themselves and they created the lie about the philosopher stone giving the drinker immortality is a lie. It just creates a really powerful healing potion. As for the gold...that's a secret I'll keep even to myself for now."
