Dark Magic
I do not own the Harry Potter characters, JKR does.
Harry Potter was a happy young boy. It was September 1st, 1991. Just a month ago, he had discovered that he was a wizard, and could escape from his aunt and uncle by going to a school for wizards, called Hogwarts. He was now on the Hogwarts train.
Within an hour of leaving King's Cross, he was chatting with a red haired boy called Ron. A query about the dangers of the wizarding world had elicited a flood of information. He was finding out about the curses, rituals and hexed objects, which Ron's brother, who worked as a curse breaker had told Ron about.
By the time they disembarked the train, he was paranoid, having been given a large diet of things which could harm him. The incident with the ghosts had not settled him, but had rattled him even more, causing him to pull out his wand.
When he entered the Great Hall, he was therefore still holding his wand. He was immediately distracted by the enchanted ceiling, the floating candles and the large number of students and was not paying attention to the stern lady who was leading the first years into the Hall.
As the Hat started singing, he looked around to see the source of the sound, saw an inanimate object singing, remembered his talk on dangerous objects and pointed his right hand at the hat and screamed out " Dark Magic". At the same time, his subconscious, let loose accidental magic, just as he had in the zoo, when his cousin had startled him, but this time stronger, as it went through the wand he was holding. The hat had paused and turned at the unexpected sound, when it saw the spell headed towards it, it twisted out of the way.
The teachers table was not so lucky and the spell hit it, causing a knife to flip and bury its pointy end in the eyeball and brain of a turban wearing teacher. As the whole school watched in shock as the teacher fell forward, dark coloured smoke rose from the body and screamed at Harry, "Damn you, Harry Potter, this is the second time you have defeated me, but I will be back".
Immediately the smoke disappeared through a window of the Hall, two things happened. The students started shouting "Voldemort is not dead and Potter has destroyed him again!" and Harry turned and started walking back out of the Hall.
Dumbledore cast a spell that caused a large noise bang to occur and the students went quiet. Harry however kept on walking, and Dumbledore called out
"Mr. Potter where are you going?"
Harry turned and answered politely, although he was trembling with fear, "To find another school, I have no desire to go to a school where my parents murderer had no problem getting a job"
Dumbledore looked at him and thought hard. Eventually he spoke " The issue has been resolved, Mr. Potter and you agreed to come to Hogwarts when you responded to your letter from us"
Harry looked at him and thought to himself, this man is as mad as he looks. Aloud however he stated "I am sorry sir, but I never responded to your letter and therefore I am free to leave and find another school. I would appreciate your sending my trunk and owl to the Leaky Cauldron, so that I can collect them."
With that he turned and kept walking, amongst the many things that Ron had told him about, was the Knight Bus, and he intended to catch it, to get back to London and find somewhere to hide after finding a bathroom to change his underwear. No way was he letting everyone realise that it was an incredible fluke. If they all believed that it was deliberate, especially Voldemort, hopefully they would be so scared of him, they would leave him alone.
AN
Read the book, he never did respond to the letter, Hagrid wrote stating that Harry had gotten the letter.
