Prologue

Betrayal

"So, how does it feel to be kneeling before your superior?"

"Superior?" A snarky voice came from the dark "Fool, he answers to no one, you Weasel"

"I didn't say you could speak, Malfoy!"

Screams resonated through the emptiness that were the Hogwarts Dungeons as one Ronald Bilius Weasley used the Cruciatus Curse on the once proud Slytherin Prince, or, at least, the would be prince, if it weren't this timeline. A body moved in the shadows, eyes cast to the ground but overall neutral-looking

"Stop it, Ron" His voice was still smooth, still entrancing, laced with the emerald and golden magic that characterized him. "Are you really that twisted to take pleasure in the screams?"

"If they come from Death Eaters like you guys, then yes"

"You sick fre-GHAA" Draco's voice cracked again as a short Crucio was sent his way

"I SAID STOP IT!"

For a moment, Ron's wand twitched, not because he did, but because the wand he was using wasn't really his. It was, after all, the elder wand, one of three Hallows that once had belonged to death itself, the most powerful offensive artifact and the wand that could do almost anything as long as the user had enough will and magic to go along with it, but first and uttermost, it was a wand, and they worked for whom they chose.

"Oh, Potter, just because you defeated the Dark Lord you think that you are all powerful, don't you?" Ron lightened up the room with a Lumos to see the mentioned male more clearly. "Harry. James. Potter… I don't get why all the girls at school were so fixated on you." The third person chained to the wall snickered slightly, but Ron made as if he hadn't heard her. "You are your parents' disgrace, you know? Not only did you not end up in Gryffindor, but you let yourself be corrupted by these slimy snakes. You made friends with all the wrong people, slytherins, lunatics, know-it-alls and cowards" Ron sighed, but he heard a chuckle.

"Disgrace? I assure you, they are very proud of me, Weasley. And even if they weren't, they are dead." Harry lifted his head, staring at the redhead with a burning emerald gaze that made him actually take a step back, forgetting that he was chained with anti-magic cuffs "How can you disappoint those who are dead?" Ron dropped the wand and hit Harry hard in the face, making him turn his head and spit out blood, but the Potter heir made no sound...only to break into laughter.

"You've lost it…"

"Have I really?" Harry's wrist snapped to the side despite being restrained by the chains that bound him to the wall. Ron only had a brief moment to turn, wide-eyed, only to find himself face-to-face with Draco.

"What?"

"Stupefy!"

Ron barely managed to dodge, but Draco smirked as he held the elder wand that the redhead had dropped just a second ago. "Weasley, you should know by now that dropping your wand isn't wise, specially when you are in presence of its true owner."

Ron's expression was terrified, but it lasted only a couple of seconds before a smirk illuminated his features. "Wow, look who's really lost it…"

"Draco, behind you!" Luna warned, but it was too late, a green spell hit Draco square in the chest as he had turned around to try and defend against the attack; he fell, his face frozen in shock but his body like that of a rag doll, hitting the ground heavily, the wand rolled on the ground.

"Ron, my boy, what did I warn you about?"

"That they were powerful dark wizards, I'm sorry, headmaster, I was careless."

Dumbledore stepped into the light, making Harry growl in anger. The young male's eyes clouded as a memory assaulted him suddenly.

He stood in front of Voldemort, Horcrux free after they had gone to the goblins and let them transfer it to an object in order to destroy it. Draco and Neville had gone to kill Nagini while Luna and Hermione searched and obliterated Ravenclaw's tiara. Meanwhile, not two, but three armies faced off in the school grounds, the Death Eaters, the Phoenix Order plus a small group of students that called themselves Dumbledore's Army and, the third group that surprised the other two sides, the Black Knights, made up of grey wizards mostly, along with about half of the Hogwarts students and lead by none other than Harry himself.

But here, in the core of the forest, everything was silent, both the Dark wizard and the Chosen One stared at each other before they raised their wands, and used their pure magic to attack each other, no longer were they messing around with silly spells.

At once, two rays of energy launched themselves from the wands, one a mix of red and black while the other one was green. Fighting for control, they pushed and pulled, sometimes calling each other, sometimes fiercely ripping themselves apart.

"Give up, Potter, you can't win against me"

"That's what villains say when they're about to lose!" Said Harry as his green magic slowly started to be tainted with golden glimpses. At the same time, everything about Harry seemed different, emerald eyes turning to golden, his black hair seemingly now a pure white, but worst was the shadow that loomed over the younger's body, with the same golden eyes and two hornlike figures on its head. The Dark Lord stared at the apparition with shock.

"What is this magic?"

The younger wizard said nothing as the pure magic that emanated from his body consumed Voldemort, leaving nothing of him. After that, everything fell back to silence; even the sounds of the battlefield had dulled out, or they might've actually stopped, the Death Eaters should be feeling the fall of their Lord, he honestly didn't know. He felt nauseous, probably because of the overuse of magic.

"...Well, who knew it'd be this easy…" He wiped the sweat from his forehead. His few moments of victory were sorely taken from him, for he was hit by a red spell and, as he fell unconscious, he could only thing one thing...

"Dumbledore." He growled, eyes flashing menacingly.

"Harry, my boy, I wish we didn't have to meet again like this..."

"What did you do to the rest of my family?"

"...Family?" Harry swore that the twinkle in the old man's eyes became brighter and he wanted nothing but to beat the lights out of those traitorous eyes. "You must be confused Harry… Your family's already dead."

"You know what I mean!"

"...Of course, I know. Ronald, could you leave us alone?" The Weasley didn't hesitate to follow the request, always the blind sheep.

"Yes, sir."

As the youngest of the red-haired clan left, Harry stared into the old man's eyes, trying to find a weakness, but finding none. It was difficult for people to be afraid when they had the upperhand. He could feel Luna's blue eyes boring into him in worry.

"What. Did. You. Do?"

"Now, let's not be too hasty, my boy."

"I am not your bloody 'boy', old git. You better tell me what you did to everyone or I'll-!"

"No need to get aggressive. They are here in the castle, some of them." The man's personality seemed colder "Some weren't very welcomed by my students, after all, they were dangerous dark wizards. Some don't even remember having been under your command."

"You…"

"Harry, calm down" Called the slightly aloof girl, but it was difficult when he felt so intensely.

"You monster, they did nothing to you!"

"But they would've, my boy. Alas, one shouldn't be sad for those who are dead, but rather pity those who decided to stay alive, especially the ones who strayed from the light...Now, some last words?"

"Fuck off"

Dumbledore rolled his eyes "So immature. We could've done so many things together, my boy." He lifted a hand and snapped a spell at Harry, a familiar, acidic green one.

He closed his eyes and braced himself, knowing that this was the end of the line. This was the moment when everything he had worked so hard to achieve was dissolved into nothingness. Still, he couldn't bring himself to feel remorseful.

But the blow never came, someone was in front of him, shielding him with their body.

"I-What? Luna? What did you do?"

"Now's not the moment Harry James Potter, I have limited time for this."

He looked at his surroundings. It seemed as if time itself had stopped, a drop of water stuck in the air. Then he noticed something else, he was free of cuffs. Luna bent down, picking up the elder wand and walking up to Harry with it and another familiar necklace in hand.

"What is happening, Luna?" He asked, trying to sound brave despite how tired he felt.

"...Listen well Harry, you only have one chance for this. I have come to give you a choice. Either you die here or you shall rise. Accept my gifts and I will grant you the power to obtain revenge."

He looked into her gaze. This wasn't Luna who was speaking to him. It might've been her body, her voice, but her right eye was a dull blue while the other was a bright golden, almost like a lit fire. She reached out with both hands, in one the elder wand and in the other the pendant that he himself had given to her in which the resurrection stone was embedded.

"What are you?"

"Time's running out, Harry James Potter. Choose. Do you want to end this life of yours or will you honor your mortal friend's wish and accept my blessings in order to be granted my power."

"But-"

"Now!"

"I…"He sucked in a sharp breath before exhaling softly. His eyes were unfocused, not looking at anything in particular"I do…"

"Perfect, close your eyes, this will hurt."

Before he got a chance to ask what she meant, white, hot, excruciating pain blasted through every pore in his body, he could feel it under his skin, as if a hundred of hot needles inserted themselves in his body or as if a strong venom was soaring through his veins. He opened his mouth to try and scream.

But he couldn't.

In his head, various images went off, so many in fact, that he couldn't comprehend what was being shown to him. Voices and noises pierced his mind as he fell to the ground once again, feeling as if he were about to be shred into pieces. He writhed in pain, trying to get rid of the horrible feeling of hopelessness. His body tensed and relaxed.

Blurry faces were shown to him and colors that his brain wasn't able to handle. He shut off from reality only to be thrown into another and another and another...

And only then did he wake up.

He blinked in an attempt to clear his eyesight and, almost as if in command, everything brightened up, at least to him. In the darkness, he heard the clicking of a tongue and the sound of a body being pushed along the cold, stone floor.

"Stupid girl, when did she loosen from the restraints?" Dumbledore huffed. "You are all young, stupid. You have yet to understand the full picture...not that it would've made any difference. Now...Where were we?"

Dumbledore turned and found himself staring into golden slitted eyes.

A/N:

A bit quick paced for my liking, but still, I sort of enjoyed this prologue :D

So, what do you guys think? I've had this idea on my head for quite a long time ago and only today was I able to finish it up and upload it. I'm a bit of a sucker for the Avengers x Harry Potter Crossovers, so it was a matter of time before this happened XD

Edit (Day: 01/2018):

I rewrote some parts of this chapter to improve it, but it is mostly the same. No need to read it all over again. I'm currently going on a corrective rampage for this story (And nothing can stop me, muehehehe!)
