A/N: We, Lady Alianne and Elspeth25 are rewriting this fanfic. The one that was up before did not please us. Also, a reviewer pointed out that there was a similarity between the fic and another one. The similarity wasn't intentional, of course. However, we were not satisfied with the way things were going, so we're rewriting this.

Summary: The Marauders and Lily have read the Harry Potter series. They started changing the future by having Peter take an Unbreakable Vow to never join Voldemort or betray the Potters. Now they are in the process of doing other things to change the future.

Disclaimer for entire fic: We do not own the Harry Potter world. It belongs to J. K. Rowling.

Remus put down the piece of paper that had appeared after they had finished the last book, which was full of information of what happened to various people between Voldemort's defeat and the epilogue. "Well, that was interesting," he said.

"Yeah," said James. "I never realized that Dumbledore was into guys instead of girls."

"Well, what do we do now?" asked Sirius. "We've got all this knowledge. We know that unless things aren't changed, Remus and I will die, along with Dora, Hedwig, Mad-Eye Moody, Dobby, and some other good people. We've realized that Snape isn't so bad after all, and we know the location of all the Horcruxes. We know how Voldemort is defeated and how the world is a better place after that,"

"We tell Dumbledore what happens," said Lily firmly. "We have him read the books, and this way, the Horcruxes can be found and destroyed right now. Then Voldemort can be killed without having James and me die."

"That's a good idea," said Peter. "In fact, we could find Ravenclaw's tiara now and hand it to Dumbledore so he can destroy it. Since it's in this room."

They all left the Room of Requirement and thought about a place to hide things. When they returned, they began sorting through all the piles of things. Finally, Remus found the tiara. They wrapped it up and left the room.

The next day, the five of them presented the books to Dumbledore and explained things. "So these books somehow were sent back in time to you?" asked Dumbledore. "And you learned what's going to happen in the future, if it wasn't changed?"

"Yes," responded Remus. "Only the future is going to be changed now. When we read the third book, we discovered that Peter was persuaded to join Voldemort sometime after graduation. He then betrayed where Lily and James were living and faked his own death. Peter was horrified by this and willingly took an Unbreakable Vow to never do it."

Dumbledore raised his brows. "Oh dear, the future is definitely changed."

He flipped through the first book, but James said, "That one isn't that important. It's the sixth and seventh books that are really important. Voldemort has created Horcruxes. Two of them are destroyed in the sixth book, and my son Harry and his friends seek out and destroy the remaining ones in the seventh and final book."

Dumbledore looked up. "Really? Then that means we can find them and destroy them now. Then Voldemort would be defeated and everything would be fine again."

"The Horcruxes are Hufflepuff's cup, Ravenclaw's tiara, Slytherin's locket, a diary that Voldemort bought, and a ring which turned out to be one of the Deathly Hallows, the Resurrection Stone," said Lily. "There were two more in the books, but they were created later. One was Voldemort's snake Nagini, which was created many years after his defeat, and the other was Harry. That was accidental, though. When Voldemort tried to kill Harry as a baby, part of his soul got blasted off and entered Harry."

Dumbledore looked thoughtful. "Well, all we need to do is find the Horcruxes and destroy them. Where were they hidden?"

"The cup was hidden in Bellatrix Lestrange's Gringotts vault," answered Peter. "The tiara was hidden in the Room of Requirement at Hogwarts, along with a ton of other stuff that Hogwarts students had hidden. The locket was hidden in a cave that Voldemort had found on a trip to the seaside with the other kids from his orphanage. The diary was left with Lucius Malfoy, who then planted it on Ginny Weasley during Harry's second year. The diary then possessed Ginny and made her open the Chamber of Secrets and cause the basilisk there to Petrify Muggleborn students. And the Resurrection Stone was hidden in the house Voldemort's mother's family, the Gaunts, once lived in."

"However, I don't think you can look for the locket now," said Sirius. "It wasn't made and hidden until after my brother Regulus became a Death Eater, and as he's only a fourth year now, he's not one yet. The cup and diary may or may not have been left with the Lestranges and Malfoys at the moment. However, the tiara and Resurrection Stone can be destroyed now. In fact, we have the tiara with us now."

Dumbledore examined the tiara, then said, "I will destroy this Horcrux, then begin the search for the Resurrection Stone and destroy it. I will also read the books that have been given to you and see to the other Horcruxes. I ask you five to not mention anything you have read, at least for now. You may go."

When the holidays ended and term started again, Lily sought out Severus Snape. She told him that she forgave him for calling her 'mudblood' last year and asked him to be friends with her again, as long as he stopped being so friendly with people like Mulciber. Snape was perfectly willing to agree, for he did want to be friends with Lily again.

The Marauders also sought out Snape. They did nothing when Snape pulled out his wand, other than to put up their hands. "Wait," said James. "We don't want to fight."

Snape was surprised, but he didn't lower his wand. He kept it raised, a wary look on his face. "We want to apologize," said Sirius. "We're sorry for all the bullying we've done to you. And I am very sorry for telling you how to get past the Whomping Willow. You really didn't deserve any of it, even if you are in Slytherin."

"And I am sorry for not telling James and Sirius to stop bullying you," said Remus. "Well, I did sometimes ask them to stop, but I should have done so more often."

Snape stared at them. "Is this some sort of joke? Or a way to catch me off guard?"

"No!" exclaimed Peter. "We're really sorry for what we did. I shouldn't have egged Sirius and James on so often. Like with the incident after our Defense OWL."

"I know we can't exactly become friends, like you were with Lily," said James. "But we truly regret how we've tormented you for the past five and a half years and we humbly ask for your forgiveness. However, we will understand if you don't want to forgive us. We just hope you'll accept our sincere apology, and we promise to never bother you again during your remaining time at Hogwarts."

Snape nodded curtly. "Apology accepted. Though whether I forgive you or not depends on whether or not you hold to your promise to leave me alone." He strode away.

True to their promise, the Marauders left Snape alone for the remaining year-and-a-half they were at Hogwarts. Lily and Snape tried to resume their old friendship, but it didn't go so well. Snape wasn't pleased to find out that Lily had decided to go out with James. When he protested that she hated James, she said sharply, "Well, during the holidays, I saw a different side to him. He was charming and sweet and a concerned person."

"But I love you!" cried Snape. "I can't stand seeing you with James."

"Sev, you can never be more than a platonic friend to me," said Lily gently. "I love you as a friend, but not as a boyfriend or potential husband. I'm sorry."

After that, the friendship petered out. Snape kept his promise of not associating with people like Mulciber, however.

Dumbledore destroyed the tiara and Resurrection Stone. He didn't make the mistake of thinking of the ring as anything other than a Horcrux, and therefore the problem in the books was avoided. He had read all the books, and concluded that as there was no access to basilisk venom at the moment, he'd have to use Fiendfyre to destroy all the Horcruxes.

Sirius decided to become serious with Elizabeth Potter, who was James' first cousin once removed, rather than going from girl to girl. Being with Beth was good for Sirius, who calmed down a bit, though he still had his penchant for pranks.

By the time they all graduated, the diary and cup had been found and destroyed also. Now all that was left was the locket, if Voldemort wasn't killed before he could create it. James proposed to Lily and she said yes. Sirius proposed to Beth, who also said yes. A double wedding was planned for next June, with Remus and Peter as best men and Lily and Beth's friends Mary MacDonald and Alice (soon to be Longbottom) as bridesmaids. Everything was proceeding wonderfully.
