The Beginning.
Harry Potter was unconscious, which in itself is not an unusual occurrence. This was anything but a normal situation because, you see, Harry Potter was dead. He had died just hours before. Let me explain;
The final battle started when Harry led the Order of the Phoenix into the Department of Mysteries to finally face Lord Voldemort after ten years of intense training. Honing his skills in every form of Magical and Muggle combat available, after watching so many of his friends die at the hands of the Death Eater scum, after taking down every member of Voldemort's inner circle including both Malfoy's and extracting any relevant information before ending their existence often in very painful ways. Harry had, what could have only been explained by an incredible stroke of luck, received intel that Voldemort had discovered the location of the Elder wand and that it was buried with that manipulative old coot Dumbledore and was planning on making a move on it.
Knowing that he didn't have long Harry immediately traveled to Hogwarts. Undetected and discreetly removed the elder Wand from Dumbledores cold dead hands, replacing it with an old stick permanently transfigured to look like the Elder Wand, all the while resisting the urge to punch the old man squarely in his ridiculously crooked nose for his part in making sure he never got a real childhood and scheming to turn him into the weapon he had become. Harry sealed the tomb back up before quickly crossing the ward lines to apparate back to the hidden location of the new Order of the Phoenix. He started to plan the ultimate and final end to Lord Voldemort and the liberation of the Wizarding world.
Harry plotted and came up with a way to lure out and dismantle Voldemort's army bit by bit, until only Voldemort was left. By transmitting false information over the link he and Voldemort share to make him believe that Harry would be alone and undefended in various locations and hoping Voldemort would keep sending people until only one location was left. The Veil Room in the Department of Mysteries, and he was the only one left to check it.
Harry could feel death in the air as his feet carried him silently through one of the many empty halls of the Ministry of Magic towards his final destination. As he walked he thought about how he got here, all that he had sacrificed for this end goal to be achieved, and thought about how much easier it would have all been had someone, anyone, other than that crazy old man had been in the know about how Voldemort fixed it so he would remain on this plane of existence. He had of course found and destroyed all the Horcruxes, it hadn't been hard to find them once he learned to look into the Dark Lords head and pluck out information, after all it's how he managed to locate every member of his inner circle.
Harry had never successfully been able to look into Voldemort's mind without being detected, that is until the night when he collected the Elder Wand. Without realising it he had become the Master of Death, and as such his entire being, mind, essence and body had changed to become more compatible with his new role as a powerful immortal being. His control over all magics, especially including the magic of the mind, had increased to the level where no one could match him. He had even managed to take control and plant subliminal suggestions to make sure Voldemort did what Harry wanted him to do on several occasions. An unintended (and painful) side effect of becoming the Master of Death was that his body became completely incompatible with the Horcrux, and as such it was forcefully expelled from his body leaving Harry feeling much lighter than he had ever felt in his life.
Coming out of his thoughts, he entered the round room and calmly said "The Veil Room" and the room begun to spin, then as quickly as it begun it stopped. Harry took a deep breath, mentally preparing himself for the coming battle, as he walked the last stretch corridor that led to The Veil Room. Harry took a deep breath and entered the room and immediately saw Voldemort standing by the Veil watching him calmly, as though he still had an army backing him, so calm and collected, that is when Harry noticed Voldemort fingering the fake Elder Wand and thought to himself 'so that's why he is so calm he believes he has a wand that can't be beat' inwardly laughing but showing no outward expression, Harry steeled himself and walked fully into the room.
As soon as Harry entered the room the door slammed shut behind him, the sound of a lock clicking into place echoed around the barren room, Voldemort's raspy voice immediately sounded,
"So Harry Potter here we are, just you and me no one to stop me from killing you this time. Today you die and I Lord Voldemort will rule the world unchallenged" Voldemort sneered triumphantly as Harry watched prepared for any sudden movements, Harry looked at Voldemort directly in the eye and holding his stare for several seconds before calmly replying
"Cut the crap Tom, I've personally destroyed your so called 'army' and now it's your turn, it was me who lured you here. Your Horcruxes are gone and now you are mortal and you will be going through that Veil just like countless amounts of scum before you" Harry took great pleasure in watching Voldemort's face pale even more than it's usual colour at hearing his Horcruxes had been destroyed. Harry's instincts immediately told him to duck, although it turned out to be unnecessary, the fake wand Voldemort had pointed at Harry fizzled and burst into flames causing Voldemort to drop it and take a step back in shock before turning to glare at Harry. He burst into laughter before pulling out the real Elder Wand and taunting
"Looking for something Tom, I think you arrived a bit too late, I have the Elder Wand" as Voldemort screamed in anger and yanked out his yew wand, shooting out a bolt of sickly green light at Harry who saw it coming but chose to stay put to show some of his new power.
Voldemort watched in triumph as the Killing Curse hit its mark directly in the chest, his sneer however soon became a look of confusion and fear, as the curse that he had used to kill so many before was simply absorbed leaving a smirking Harry completely unharmed.
"You lose Tom, it's time for you to die and this war to end" Harry confidently said as he looked toward the Veil and waved the Elder Wand in an intricate pattern too quickly for Voldemort to follow. The Veil started to churn uncontrollably before a tentacle of pure energy shot out of the Veil to wrap itself around Voldemort, causing him to drop his wand in shock as he was dragged screaming into Veil of Death. Harry had done it, he had finally beaten Voldemort and ended the war once and for all. He was so tired, tired of everything he had to do in this war, the people he had to torture and kill, the lines he had to cross, the people he lost and he knew what to do. Without one look back Harry confidently walked through the Veil, that had returned to normal and disappeared from the Wizarding World forever.
