I don't own


Dumbledore sat in his office at Hogwarts, contemplating the short, but blunt letter he had received from Lord Slytherin:

Dear Headmaster Albus Dumbledore,

I know that you are most likely shocked to hear from me, but I have an offer for you, an offer that I daresay you will most likely want to consider strongly before voicing your response. Here it is, My Father and I, in a duel against you and a chosen partner. Winner takes all, two rules, no unforgivable, and no interference. This war must come to an end.

Lord Slytherin.

Dumbledore knew that this was a once in a lifetime offer, a chance to have a fair duel, two against two, to decide the war. He knew that he really had no choice but to accept, and find a suitable dueling partner. He thought immediately of his brother, Aberforth Dumbledore, who to the surprise of most is actually an excellent dueler, and can give Albus himself a run for his money. Deciding to floo him as soon as possible, Dumbledore wrote a response to Lord Slytherin and sent it off with Fawkes. He can only hope Abe and him can stand up to the two Dark Lords.

There was a flash of flames, and Fawkes appeared in front of Harry and Voldemort. Harry grinned at his father, and went to take the letter.

Dear Lord Slytherin,

You are right, this war must end. Therefore I Albus Dumbledore hereby accept your offer and request that we meet under a truce with a ministry official to arrange the details of the location and such. The location of the meeting is yet to be decided as I have to inform the ministry. I will inform you of the neutral meeting spot by tomorrow morning.

Albus Dumbledore.

Harry showed the letter to Voldemort.

"So, it is almost to an end. Good, you were right Harry, it has to end. If we take down Dumbledore and the ministry in one go, then we should be clear to deal with Merlin," Voldemort said thoughtfully.

"Right, but I think if we all teamed up on him, we might have a chance, I'm uneasy about the girls being in that fight, but I know we don't have any choice in the matter," Harry was not happy with that fact.

"We have to have faith in them that they can handle themselves, we've seen them fight before, and since then they have only gotten ever so stronger, they will be fine," Voldemort explained slowly to Harry. Harry knew he was right, he just didn't want Ginny to get hurt. Harry nodded, and went to go explain to his wife what was agreed upon.

Two days later:

Harry and Voldemort stood at the entrance to the Dusty Unicorn, an old bar. Why they had chosen this spot for their negotiations, Harry hadn't a clue. Harry and Voldemort walked inside and saw the minister of magic sitting at a long table with Albus Dumbledore, and another old man, Harry assumed this was the Aberforth Dumbledore that he guessed Albus would select as his dueling partner. They both swiftly sat down without saying a word.

"Alright lets get this over if, the duel will be a two on two duel, and the winning pair gets the losers unconditional surrender. Now, will the duel be to the death, first blood, knock out, or surrender?" Minister Fudge questioned all four wizards, jotting things down all the while.

"To the death," All four of them answered almost immediately.

"Any specific rules?"

"No interference, no unforgivable, and I believe it would be only fair to add no parseltongue magic," Albus Dumbledore put this out, expecting heavy resistance for this rule. To his and his brothers great shock, both of the Dark Wizards said nothing, and merely nodded. They could still fight just as well using only regular magic.

"Very well. I believe a good spot for the duel would be a clearing on an island off the coast of Britain. We will take about 3 weeks to build a suitable arena and let the world know" Minister Fudge finished writing out the magically binding contract, and then handed it to the Dumbledores "Sign please," as they both signed it there was a flash of light. "And you two also," Fudge then handed the parchment to Harry and Voldemort, who both signed it after quickly scanning the contents to make sure there wasn't any loopholes or anything. Fudge took the contract, and stood up. "Excellent, you will be owled the coordinates the day before the duel, to insure nothing is done to give either parties the advantage or disadvantage, have a nice day," With that, Fudge tipped his hat and left. Harry and Voldemort followed his lead and apparated away before either of the Dumbledores could say anything. Now that hard part, seeing their wives and explaining to them the contract…this could be bad.

After about an hour of being screamed at, Harry and Voldemort made it out of the house alive, to go relax and be thankful the yelling is over. Meaning they locked themselves in the nearest wine cellar for two hours.

The next day it was time to explain to all the death eaters the conditions of the duel. They were not exactly pleased that they were being robbed of the chance to 'prove themselves' to their masters. But after a death eater got mutilated by Harry and Voldemort having cast a spell on him at the time, they realized something. Don't complain about ANYTHING when your Dark lords both have horrible hangovers, else you will have a painful experience, not necessarily be killed.

The next three weeks passed fairly quickly, Harry and Voldemort spent hours each day training with the death eaters, teaching them more deadly spells, and practicing dueling as father and son. They trained the death eaters because, while they had signed that contract that said the looser will surrender, well the death eaters only listen to Voldemort, and if he dies, there is no one to command them, meaning they can do whatever the bloody hell they choose to do. Not that Harry or Voldemort even thought of what would happen if they lost, they knew the chances of them loosing are very low. But they had to at least pretend that the duel was difficult, else the public would believe they had cheated. They also spent the evenings spending quality time with their wives, they knew the chance of them dying were very low, but Ginny and Lily weren't going to take any chances, and so spend as much time with each other as each couple could.

And so the day of the big duel finally arrived. When the Dark Lords and their wives apparated the arena, they were shocked at just how…massive the place was. It was about the size of two football field put together, they had plenty of space. And as they looked around, there had to be at least a million people cheering and waiting to see one of the greatest duels of this age. All of a sudden there was a very loud voice over the roar of the crowd as Minister Fudge addressed the crowd

"Greetings to all! Welcome to what will soon be known as the greatest duel ever seen in the history of magic! We will waste no time in this duel, the fight will be to the death. It is to be Lord Voldemort, and Lord Slytherin, fighting as a team against the two brothers, Albus and Aberforth Dumbledore. The winner of this duel will also be the winner of the war that has been going on for the past several years. Good luck to all!" with that several aurors escorted the Dark Lords wives up to a special viewing box.

The duelers walked to the center of the dueling arena and then there was a magical gong, as it initiated the duels prelude. The four wizards bowed to each other and as soon as they finished, all three immediately sent blasting charms towards the others, while Harry instead dodged. As if by some instinct, Albus and Voldemort started dueling with only each other, and so did Abe and Harry.

Aberforth and Harry:

Harry dived to the side as Abe sent a stunner towards him, while rolling Harry used the electricity in the air to fly upwards a few feet and sent a powerful white spark towards him in the shape of a curse, to make it seem like he was using magic. After all, he didn't want to bother with the staff so he decided to use lightning instead and make it seem like he was using magic. Abe blocked it by conjuring a stone wall, he then leaped over the wall and used his magic to amplify his jump so he soared slightly underneath Harry and sent a reducto towards him. Harry, not expecting the attack, took it in the stomach and fell about twenty feet to the ground. Abe landed and ran over to him, intending to finish him off while he's hurt. As soon as Abe got to Harry, he surprise him with a bolt of lightning to his wand. There was a tremendous explosion as the wand blew up, causing Harry and Abe to fly through the air before landing with a thud several yards apart from each other. Abe seemed lost of what to do during a duel when his wand had just been destroyed. So picking himself up, he ran over to Harry, and started punching him. Harry took a right hook to the nose before he side stepped during another swing, and swept forward with his left foot, knocking Abe to the ground. Harry, not giving Abe any chance to recover, quickly curb stomped Abe in the jaw. And then Abe rolled away and kick out with his leg, also knocking Harry over. Abe then lifted his leg and kicked downward, hitting Harry with his heel in the stomach. As Harry doubled over in pain, Abe stood up, kicked Harry in the side of the head. As Abe stood there catching his breath Harry stood up and with both of his hands clasped together, smacked the side of abes face. With Abe on the ground, Harry balled up his fist and charged it up with a small amount of electric charge, before slamming it into Abe's face, there was a small white spark as his fist connected with abes nose, and then Aberforth Dumbledore, was dead. The crowd screamed in fear as Lord Slytherin triumphed over his foe. With a deep breath, Harry sat down next to the corpse, and watched his father and Dumbledore duel, as Harry sat down, he saw his father hit Dumbledore in the side with a skewering curse.

Voldemort and Dumbledore:

Voldemort blocked Dumbledores blasting charm before it came even close to him. With a sadistic smirk on his face, Voldemort sent a powerful blood boiling curse at him as he sidestepped a stunner sent towards his eye. Not giving Dumbledore any time to recover Voldemort sent a series of blood freezing, blood boiling, concussion, cutting, and blasting curses at Dumbledore, who managed to dodge all the most harmful ones, before getting hit by the blasting curse, as he flew through the air Dumbledore sent back a powerful explosion hex, hitting Voldemort in the chest while he was distracted glancing at his son. Flying through the air Voldemort managed to cast a slowing spell on himself and landed safely, sending a spell that was normally used only to collapse large buildings at Dumbledore, who, recognizing the spell, used a magically amplified jump to leap out of the way of the deadly curse. While he was in the air Dumbledore sent three blasting charms at Voldemort in rapid succession, Voldemort thinking quickly, conjured a stone wall, and then two walls behind that, to block all the curses and temporarily give him some cover with the dust. While Dumbledore couldn't see anything threw the cloud of dust, Voldemort conjured several metal spears and banished them all towards Dumbledore, hoping to get at least one hit. He got lucky, two of the spears got Dumbledore in the leg, one in his calf, the other right above his knee. As Dumbledore bent over to try to remove the spears, Voldemort cast a skewering curse and nailed a direct hit on Dumbledores side, causing blood to spill out. As Dumbledore screamed in pain, Voldemort sent a piercing curse and hit Dumbledore in the forehead, and kept going out the back of his head, and so Albus Dumbledore died, with a hole in his skull. Voldemort looked over to check on his son, and saw him walking towards him.

Father and son, as one clasped arms and together, raised them high in their victory. Finally, they had taken down the Ministry and Order of the Phoenix resistance all in one arena. Now they had one last task before they left the magical world, they had to eliminate Merlin. Or die trying.

Two minutes later:

"NO. I CANNOT LET THIS HAPPEN, I WILL DESTROY YOU FOR YOUR CRIMES," a loud angry echo boomed out from the center of the arena. Harry and Voldemort looked around for their wives, and relaxed as they apparated to their husbands side.

"Its time to finish this," Harry whispered into Ginny's ear as he gave her one last kiss. Lily and Voldemort merely looked at each other, the other already knowing what they were thinking.

There was a flash of light as Merlin appeared before them, he wore deep blue robes and had his hood down, so they could see his face. It was ancient. His dark blue eyes seemed to know everything. He had silver hair down to his shoulder, and a long silver beard similar to Dumbledore's. Knowing that they had little time before his aura would start draining them, they all acted immediately, Harry and Voldemort put their power together and managed to summon a wyvern. A wyvern is much larger and much more powerful than any other creature in the world. They one they summoned appeared to be a dragon made of stone, but more snake-like. And he was massive, his eye was about the height of Voldemort, to make a comparison. As the wyvern shrieked and leaped towards Merlin, Harry flew into the air and started focusing all his power on creating a lightning storm that would continuously strike merlin and only merlin. As he was doing this Voldemort summoned all his death eaters and anyone else on their side to assist them. While Ginny and Lily simply started sending massive spells towards him, venom tsunamis mostly. It was a spell that sent a tsunami made of pure basilisk venom towards the enemy. After that there was a large flash of white light and the ground shook as merlin vanished all the nearby traces of magic, every spell that had been sent towards him, whether it was from Lily and Ginny, or the hundreds of death eaters that had suddenly appeared in the arena, it was all vanished. With an angry blood curdling roar, the wyvern fell as merlin cast a spell at the beast that appeared to be a large ball of white energy that split up into eight different balls of energy and hit him, each causing a tremendous explosion. Sharing looks, Harry and Voldemort each cast the most powerful thing they could at Merlin, Harry's choice being the strongest bolt of lightning that he could muster, while Voldemort cast a self invented curse, he called it the Devils Downfall curse. He only used it once, but the one time he cast it, it actually made him fear using it because of how powerful it was. Lily and Ginny both sent meteor curses at him. All four attacks hit him at the exact same time, and the arena was blasted apart as Merlin literally exploded, his body seeming to cause as much destruction as a small nuke.

Finally, the true battle was over. But at what cost?

Haha! weren't expecting that were you!? Oh well.
