To Change the Past

Chapter One

Living in the Present

Saviour-of-the-World, Boy-Who-Lived, Chosen One and 21-year-old Harry Potter sat in the Headmasters' Office at Hogwarts, contemplating life through the amber depths of his glass of Firewhiskey.

His demons of the past refused to stop passing in front of him. No matter what happened, he could always see their faces. Ron, Luna, Susan, Cho, Fred, George, Ginny, Bill, Fleur, Charlie, Arthur, Molly, Remus, Tonks, Dumbledore, Draco, Sirius, Cedric, Hermione...

The last name really set him off. Her loss had hit him the hardest. Even now, 4 years later, he still couldn't bear to think of her. Of her smiling eyes, her perfect nose, bushy hair and succulent mouth...

All of a sudden, he was pulled from his dark thoughts by the arrival of his one surviving friend, Neville Longbottom. The only person to have suffered as much as he. His brother in all but blood. The one who stood beside him to the very end, helping him to bring around the end of the Dark Lord Voldemort. The one whom he wanted to consult on this matter.

"Drinking doesn't help all that much Harry," he started half-heartedly. "Trust me, I've tried."

Hedwig, who had alighted upon Harry's shoulder trilled, and a weak chuckle came from him. "You may be right there mate, but you can't deny the peace it brings."

This time it was Neville who chuckled. "Alright, you win. So what did you want me for?"

"Take a seat." Harry got up to pour out another tumbler for his brother. As Neville took it, he sat back down and hesitated, not sure whether or not to say what he was thinking. "Hey Nev, what if I were to offer us a chance to change everything for the better, to fix all the wrongs?"

The glass froze on its way to Neville's mouth, slowly lowered once more to the table. "Explain."

"Remember when we were searching for the last Horcrux? The one that was in me? Well, after I did old Moldy in, his memories started assaulting me. All of them, from when he was born to the day he finally died, are now sitting inside my head."

Neville blanched. Harry had been literally forced to live another life in the last 6 months! To Neville, it was certainly an explanation to his somewhat detached behaviour in the past half year.

"Did you know what he was researching at the very end? I'll let you know in two words – Time Travel."

"Time travel?" he parroted.

"Yea, and the day we confronted him was just as he'd figured it out. Only reason he couldn't do it was because he didn't have the necessary requirements. Do you realise what this means?" Now, Harry was pacing the office, the portraits following his moves attentively. "We can make it all right! We can change the past!"

"Er, Harry? What good would that do us?"

Here, Harry sat back down again. "When I was living through Tommy's memories, you know what I realised? It wasn't all his fault. It was his surroundings that dictated his future corruption. It was something Albus even alluded to in his Pensieve lessons back in 6th year."

"Harry, what exactly are you proposing?"

"Mate, I'm saying we should go back before he was born, and make it better for him! Think about it – no Dark Lord, no deaths, no Slytherin rivalry rubbish. The world will prosper from it!"

"Ok Harry, if you really think it's the right thing to do, how do we go about it?"

"Well, I was thinking..."

**********

Harry and Neville stood on the hill in what was left of Hogsmeade. In Harry's pocket was a shrunken trunk, the only thing they were takinbg into the past. In the six months since Harry's revelation, they had prepared as well as they could for their trip to the past.

Harry, or rather James Harrison Evans, stood at his 6'1 frame, garbed in a simple travelling cloak and his dragon-hide boots, incidentally Hermionie's gift from their engagement...

He jerked himself from his reminiscing to look upon Neville, now named Frank Neville Evans. For their trip to the bast, they had adopted the persona of two brothers, now blood-brothers due to a ritual from Riddle's memories. Harry had shoulder-length brown hair, though had retained his mother's green eyes. He had higher cheek bones, and together these helped to make for a totally different look altogether. Neville appeared similar, except with his natural brown eyes instead.

Between them, they had an incredible amount of resources in the trunk. 72,000,000 galleons – the proceeds of the entirety of the Potter, Black and Longbottom estates. Gryffindor's sword, Harry's wand and Voldemort's as well, though now Neville used it to great effect. Their journals, detailing all they knew of the past. His prized possessions – Basilisk battle robes, his father's invisibility cloak, the marauder's Map. And finally, Hedwig – Harry's erstwhile phoenix companion, transformed following her apparent death at the hands of Voldemort.

"You ready girl?" A soft trill marked her affirmation. "Nev? Or should I say Frank?"

"As ready as I'll ever be." He chuckled back. Then, Harry nodded to Hedwig, and in a burst of brilliant white flame the trio disappeared.

Three figures appeared in a flash of light on the highest hill in Hogsmeade village. The snow on the ground arround them instantly evaporated.

"Are we here?"

"Only one way to find out." Tempus.

10:10 am, December 3rd, 1926. "There you go. We did it! Let's go to Gringotts." With a non-existant 'pop', the hill was bare once more.

Neville and Harry, Frank and James, reappeared on the top step of the Wizarding Bank. With a final nod to eachother, they walked through the impressive white marbles threshold and into the Goblin territory.

Inside, the bank looked identical to what it had been in the past, or rather the future. The two brothers marched straight through to an unoccupied counter, and sat down.

"How may I help you?" The obviously bored goblin attendant inquired.

"We would like to open a new account in the name of Evans."

The goblin sneered at them. "I doubt you have enough gold to interest us."

Harry smirked back "Oh really?" He took the trunk out of his pocket, enlarged it and opened the money compartment for the goblin. "Is that enough?"

To say the goblin was shocked would be an understatement. Now, he was all smiles (well, as much as a goblin could smile) and praises, opening the account with all due haste. Within minutes, Frank and James were the holders of the third-largest vault in gringotts, barring those of Merlin and the Four Founder's. Leaving the attendant in a slight daze, the two brothers left the bank, chuckling to one another.

A/N: Well, there's the first chapter in my first fanfic. Please let me know what you think, and what to change, no matter what it is!
