Harry Potter in a Different World-Chapter 1 The Spell

Fifteen year old Harry Potter was not having a good day. In fact, he was having a damn right awful day to be truly honest. Firstly, his best friend Ron had failed to wake him up for breakfast, he then proceeded to slip in the shower, falling flat on his back while to reaching for the shampoo, luckily he had managed to grab hold of the shower curtain as he fell otherwise he would be held captive by Madam Pomfrey in the hospital wing for having broken something. He then tripped on his robes flying headfirst into Deans four poster bed, after detangling a smelly red sock from his head he attempted to tame said unruly mop; without much success.

By the time Harry had jumped over Mrs Norris on the 2nd floor and sprinted on to the Great Hall for breakfast, he was already 10 minutes late for his first lesson. And it just happened to be Potions with his most hated professor; Professor Snape, who just seemed to hate him, no, Snape seemed to loath him with a passion for which Harry couldn't understand except that it had something to do with his father.

Grabbing the nearest piece of food, which happened to be an apple on the Hufflepuff table, Harry raced to the dungeons chewing furiously resulting in the juice dripping down his chin. Coming to a halt outside the classroom Harry glanced at his watch. Damn. He was now 20 minutes late. Snape's going to kill me, Harry thought while wiping his chin with the hem of his robe.

Harry knocked on the door and slowly entered the classroom. Yep, Harry thought. Snape's going to kill me. As Snape looked up from his desk, Harry could see that his professor's face was slowly turning from his normal pale complexion to red with rage. His mouth was twisted in a cold evil smile as he stood up from his desk, his eyes glittering in undisguised hate.

"Well, well, well...If it isn't Harry Potter. How glad we are for the Boy-Who-Lived to finally grace us with his presence." The Slytherin's badly muffled laughter echoed throughout the classroom while the Gryffindors were torn between glaring at the Slytherin's and shooting him pitying glances while Ron, who Harry saw, was trying to sink into his seat, the tip of his ears turning red.

Harry took a deep breath. "Sorry I'm late Sir, I was..."

"SILENCE!" Snape barked. He swooped round his desk, robes billowing dramatically behind him. Making him look as if he was gliding across the classroom. Standing directly in front of Harry, his eyes narrowed and his mouth twisted like he had swallowed something unpleasant.

"I for one do not want to hear your pitiful excuses as to why you are late to my lesson. You will have a weeks worth of detention, with Filtch, including the weekend. Oh yes Potter" Seeing that Harry was going to interrupt, he stood straighter addressing the whole class with his sharp cold voice echoed throughout the dungeons.

"Including the weekend. What a shame. Potter will miss Quidditch, no Quidditch cup for Gryffindor this year I think... Sit down and I want a 3 foot essay on the properties and functions of the melloacidic potion seeing as you too late to start brewing a de-aging potion like the rest of your peers" Snape sneered, and with that, Snape stalked back to the front of the classroom and sat back down at his desk.

Stomping to his seat next to Ron. He slammed his bag down and dug in his satchel for a piece of parchment, quill and ink.

"Oh and Potter...50 points from Gryffindor for being late and a further 10 for being disruptive". Harry refused to look up. If he did, he wasn't sure if he could stop himself from snapping at Snape saying that if it was one of is precious Slytherin's that was late he wouldn't take 50 points or get a detention. So Harry settled to glaring at his parchment instead while trying to ignore the Slytherin's who were still quietly laughing.

Harry caught Ron's eye as he was adding the crushed lacewing flies into his cauldron and he whispered "I'm really sorry mate. I was up late myself and I totally forgot to wake you."

Smiling kindly at his best friend who obviously feared that Harry was going to snap at him he said "It's alright Ron. Don't worry about it."

Malfoy who was watching the exchange with amusement whispered "Hey Potter, how's dear Weasel going to cope without you holding his hand. Hell, he might even need you glasses Potter so that the Weasel will be able to see the quaffle seeing as he can't afford his own. I'm not surprised though, have you seen the size of his mother? She probably spends all the money they get on food." The neighbouring Slytherines snickered while the Gryffindors glared at them. Snape, unsurprisingly hadn't said anything.

Ron, who had bristled with anger at the obvious insult to his mother and the dig at the fact that his family have little money, he couldn't control the famous Weasley temper and took out his wand and shouted "Shut it Malfoy! Don't you dare say another word against my mother! Have you seen the state of yours? Does she always look like there's something foul under her nose? Or is it just because your presence repulses her?" Malfoy then shot up from his seat, the noise of the stool hitting the stone floor gaining finally attention of Snape who had suddenly looked up at the noise.

"You'll pay for that Weasley," Malfoy sneered. "Let's see how you like this!" With that he raised his wand.

"WEASLEY, MALFOY SEECE THIS BEHAVIOR AT ONCE! PUT YOUR WANDS AWAY OR YOU'LL BOTH FACE EXPULSITION!" Snape bellowed, spittle flying everywhere.

But neither Ron nor Draco made any direction to comply with the potion masters instructions.

Suddenly, three things happened at once which would consequently lead the entire wizarding world into shock and devastation.

Malfoy whose wand was raised confidently in front of him shouted "Nella potenza dei dodici Dei, ti mando indietro al tempo sconosciuto!" And with that a beam of green light followed by line of silver and gold intertwined had erupted from his wand and headed straight for Ron.

Harry, who hadn't recognised the incantation that Malfoy had spoken but it defiantly wasn't English or Latin, was paralysed with shock and felt a sudden rush of fear and nausea as he saw a green light erupt from Malfoys' wand and headed straight towards Ron who still hadn't moved. Fearing for his best friend's life-Harry shot up off his seat with and collided with Ron who had suddenly ducked as soon as Harry got up off his seat, knocking his de-aging potion all over the desk and in turn all over Harry.

The green light which now had a glow of gold and silver hit Harry instead of Ron. The spell had ignited the potion that was splashed in Harry's robes which left Harry screaming and writhing in pain as he dropped to the floor in a shower of electric purple and silver flames.

The class watched in a mixture of horror and shock as Harry continued to scream on the floor, clawing at the stone floors with tears escaping from his closed eyes.

Snape was frozen in fear. He knew what that spell did, as he was one of those involved in creating new spells for the Dark Lord as he was fluent in many different languages that others wouldn't know, as the dominate language for creating spells was Latin. There was no possibility of stopping the spell, and mixed with the de-aging potion. He dreaded to think what would happen, as so he could only close his eyes and wait for whatever was to happen to stop.

Harry had stopped screaming and was now whimpering and he started to curl himself into a ball as he started to shrink. The purple and silver flames were now gone, and Harry was now surrounded by a faint white glow and had started to hover two foot in the air. Firstly his arms started to shrink and then his legs with loud cracks as the bones were snapped and shrunk, this was followed by his entire body which came to resemble that of a 5 year old. His hair grew shorter but seemingly more silky and tameable; his nose grew smaller and had little dimples in both cheeks. A stronger more prominent white glow had began to embrace his head and continued to wrap his neck, back and down his arms and legs until all that could been seen was an immense white glow that hovered in the air. It sent off waves of magical energy which made the occupants in the room tremble and the vials of potions on the shelves rattle against each other.

And all of a sudden, with a final blast of silver light, Harry was lifted higher in the air; wind seemingly coming from nowhere, which had parchment flying everywhere in a whirlwind around Harry. Just as everyone's eyes were beginning to get accustomed and to the scene in front of them, a gold light shot out of Harry's chest engulfing him in a cocoon of which consisted of white and gold and with a final loud crack, Harry had disappeared.

Silence.

Silence reigned in the classroom, no one dared to speak, and Snape who had dared to open his eyes again was still in shock, staring at the spot where Harry once hovered, his knuckles turning deathly white as he clutched the edge of the desk for support.

Hurried footsteps was heard in the corridor outside the classroom, and the door was quickly slammed open revealing a very dishevelled Dumbledore, with his glasses askew, he was looking as if he had just ran all the way from his office to the dungeons. He surveyed the classroom; from the smashed potion bottles, several cauldrons of a ruined potion of some sorts, bits of parchment that seemed to form a circle around one desk and the unconscious form of one Draco Malfoy who was ungraciously slumped on the floor, wand still in his hand.

"Se...Severus..." Dumbledore panted, "What happened? The castle wards alerted me to powerful magical time serge. How this of could happened? A time surge? Who was involved? What happened?"

Snape opened and closed his mouth a couple of time before taking a deep breath and clearing his throat before he told the Headmaster exactly what had happened. "And...and then Pot-Harry disappeared and he won't be coming back. Trust me Albus, I know what that spell does and I'm certain that Harry isn't in this world, even this dimension. I'm truly sorry..."

No one had picked up on that the feared Potion Master had called his most hated student by his first name or that he had apologised and looked as if he meant it. They were all in utter shock, Harry Potter wasn't coming back, and even the Slytherin's were looking pale and uncertain.

Albus Dumbledore looked and felt all of his 103 years as he slumped and sat down against the nearest stool. He knew of what Severus spoke of was true, he could see the truth in his eyes without having to result to Legilimency to find out what happened, but he couldn't help worrying about what was to become of Harry, who was like a grandson to him.

"Er...Erm Professor Dumbledore, is what Professor Snape said true? Isn't Harry coming back?" Hermione whispered as she slowly walked up to the Headmaster, Ron right behind her.

"Yes, I'm afraid so Miss Granger, Harry James Potter is indeed not coming back. Ever."

With that said, Hermione broke down in tears and would have collapsed on to the stone floor if Ron hadn't of caught her. Who himself was looking shocked and ashen faced, as was the rest of the class.

The fate of the wizarding world was uncertain as was the life of a boy once named Harry James Potter who had no idea who or where he was.

-END CHAPTER ONE-

The spell that Draco said in English is "In the power of the twelve Gods, send thee back to the time unknown!" And I translated the spell from English into Italian using a simple internet translator, sorry for any mistakes. I chose Italian because I thought that it sounded the best.
