Disclaimer: I don't own anything but the plot.
Harry Potter stared blankly at the ceiling, mind dead to the world. The summer was half-over and he had yet to do anything productive. The days had passed in a blur of meals and falling into a sleep filled with cackling laughter and sickly green lights. Today was no different, at least for him.
Harry was startled out of his reverie when his bedroom door slammed open, revealing one Remus Lupin half-clad in an invisibility cloak. Without a word to Harry, Remus cast a spell, sending all of Harry's belongings flying into his trunk in a haphazard manner. A second spell shrank the trunk while a third one hit Harry who glowed slightly. Harry felt as if something intangible had been lifted off him, giving him a sense of freedom.
"Come on Harry, we've got to go before Dumbledore realises that the wards have been tampered with!" Remus spoke urgently.
Harry simply blinked in confusion. "Just where are we going, Remus?"
"I've got a safe house set up somewhere so that we can train and prepare for the defeat of Voldemort, by any means necessary."
Harry quietly considered the idea. He was sick and tired of the shadow of Voldemort hanging over him, or more people close to him dying because of the snake-faced bastard. He decided there and then, no matter the means, Voldemort would go down for good. However, this meant training in areas of magic not available at Hogwarts. It would seem that the best possible option available was to follow Remus.
"Alright, you've got me. Let's go!" Harry's attitude did a complete one-eighty. Gone was the sullen Boy-Who-Lived; in his place was an excited, determined teenager who knew exactly what he wanted.
Remus smiled fondly at the image before throwing in one final word. "By the way, that last spell I cast? It removed the under-age tracking charm, meaning you can now use magic without fear of repercussion." With that, he grabbed hold of Harry and disapparated.
-Two Years Later-
It was graduation day, the day that Harry was due to graduate from Hogwarts had he continued his education there. However, that day was no longer one of happiness, but one of sadness and fear, for it was the day that Voldemort and his Death Eaters attacked Hogwarts.
Much had changed in the two years since Harry had vanished together with Remus. There had been a large outcry amongst the wizarding public, claiming that their saviour had abandoned them. Even the Order of the Phoenix, together with Dumbledore, Hermione and the Weasley family, had given up hope after a year of trying and failing to find the both of them.
With the morale of the light side at an all-time low, Voldemort's following had increased dramatically, allowing him to slowly take control of the British wizarding world, starting with the Ministry of Magic. Two years on, the only resistance that remained resided in the school of Hogwarts. Now, Voldemort aimed to crush the resistance once and for all, beginning with the death of Dumbledore.
The grounds of Hogwarts were in chaos. Different spells filled the air as the Order of the Phoenix and any willing student defended against the onslaught of the Death Eaters. While the Death Eaters had strength in numbers, the Light side was more coordinated and had trained endlessly for this purpose.
Voldemort and Dumbledore were engaged in battle in the middle of the grounds, spells flowing from their wands, spells flowing from their wands, neither gaining the upper hand though it was evident Dumbledore was tiring. It was taking everything he had just to keep up with the Dark Lord. It was at the moment that Dumbledore suddenly stumbled, leaving him off-balance and vulnerable to an attack. But before Voldemort could capitalise on the opportunity, something else caught their attention.
A massive orb of light had suddenly materialised on the grounds, not far from where Dumbledore and Voldemort were. It was slowly increasing in brightness, until it became so bright that everybody had to shield their eyes or risk turning blind. by the time they could see again, the situation on the battlefield had changed.
A translucent bubble of some sort had sprung up around Dumbledore and Voldemort, obscuring everyone' view of whatever happened within. One notable difference, however, was that instead of the expected two blurred outlines, there was now a third person within the bubble.
On another part of the grounds, a cloaked figure had begun his task of taking down as many Death Eaters as possible, en route to one particular Death Eater named Bellatrix Lestrange. What was unique about this person was his method of killing the Death Eaters: instead of casting spells, the man used his bare hands or a weapon hidden up his sleeve, moving silently and quickly, like a wolf.
Dumbledore and Voldemort gazed at the newcomer in surprise. The stranger had shortly-cropped hair, and was wearing a simple T-shirt and jeans. He held no wand in his hands, but his stance was one of confidence, despite appearing unarmed in front of two of the most powerful men in the world. His most identifying features, however, cemented the two men's beliefs of his identity: a lightning bolt scar on his forehead and bright green eyes.
Voldemort broke the silence first. "Potter!" He hissed in disbelief.
"Why hello Tom, how've you been? Not too bad I presume, seeing as how you've almost taken over the British wizarding world. But, enough of pleasantries, I have a certain snake infestation to deal with." Harry smirked.
Before Dumbledore could interject, Harry cut him off. "I have nothing to say to you old man, so don't even bother. I'm more than aware of what your actions, or lack thereof, have done to me. I'm taking down Voldemort but not as a favour to you all, but merely to get rid of a potential threat to my future."
That being said, harry threw his first curse, wandlessly. Voldemort was almost too startled to raise a shield, but managed to do so in the nick of time, only to watch in horror as it collapsed immediately. Subsequent attempts to do the same thing failed as every curse Harry threw tore down even the strongest shield Voldemort could muster.
The Dark Lord was thus forced to conjure objects or dodge the incoming spells in order to have the slightest opportunity to attack. He was in for the second shock of his life when the infamous unstoppable Killing Curse smashed against an unknown shield harry had summoned and came to a halt, before being absorbed into the shield.
"Surprised, Tom? I didn't just hide away the past two years doing nothing; I was researching a way to stop the unstoppable Killing Curse and I found it," Harry stated in a mocking tone.
Harry then conjured some lions to distract Voldemort for a while before launching his attack plan. a wave of his hands immobilised Dumbledore, preventing him from doing anything, even accessing his own magic. harry then bent down and began inscribing runes into the ground, finally revealing his wand for this task.
Harry moved in a rough circle around Voldemort, pausing every few moments to either block a spell sent his way or conjuring more distractions for Voldemort. Just as he was done inscribing the runes, Voldemort had finished dealing with his many distractions.
Blocking another spell from Voldemort, Harry initiates the next stage of his plan. he flared his magic, causing the runes on the ground to light up and activate. A perfectly spherical barrier sprang up, this one glowing a faint gold. Immediately, Voldemort could feel his magic slipping away, as if something was draining it.
"Do you know that when babies are traumatised, they tend to have outbursts of magic? parents would then cast a shield around them, one which would be able to absorb the erratic magic flowing around. I've expanded on that, such that the shield would forcibly absorb any magic within its boundaries, even those from magical objects, rendering portkeys useless." Harry said conversationally.
Hissed curses and expletives few from Voldemort's mouth as he tried all he knew to break down the barrier, but as soon as the spell left his yew wand, it instantaneously dissipated and was absorbed by the barrier.
"It's no use, Tom, the barrier can't be taken down, unless I wish it to be so. Just quietly await your death, alright?" Harry chuckled disconcertingly. Within a few minutes, it was over and Voldemort lay on the ground, dead forever.
Harry let our a breath he didn't know he had been holding. A wave of his wand took down the barrier and removed all traces of the runes that had been inscribed. Turning to Dumbledore, he freed the aged wizard and gave a wry smile. Without another word, he vanished from the spot, leaving Dumbledore to deal with the uproar that was bound to occur.
Harry reappeared in the safe house where Remus already was. "Problem settled. What about yours?"
Remus smiled at the look of sheer joy on his adopted godson's face. "I doubt anyone would be able to find all the pieces of Bellatrix after what I've done."
harry laughed joyously. "So what are we going to do now, Remus? Neither of us wants to have any more contact with the wizarding world any longer. I've emptied all of the Potter vaults and changed all our wizarding currency to muggle currency. Basically, we can just up and leave now."
"Then that's what we'll do. I've found that the United states hardly has a wizarding population. Plus, I've actually stayed for a short while at one of the towns before, so we'll settle down at that place first."
"Oh really? Which town?"
"Forks, Washington."
A.N.: Ok, this is my first time writing a Harry Potter and Twilight crossover. To be clear, this story is definitely going to have slash, so if you don't like it don't read it. Please review, but I do not wish to have readers telling me what pairings they would like to have. I've already decided and nothing's going to make me change my mind. Thanks in advance!
