Chapter One:

Meet the Marauders

Freda and George Weasley snuck into Harry Potter's dormitory, their brother's best friend, their friend as well, at Hogwarts. They wanted to look at the Marauder's Map, which they had given to him. They needed to know where the teachers were, as it was late at night, and the twins were going to decorate the Great Hall for Valentine's Day. They didn't actually go to Hogwarts, they left halfway through the last year, but they were some of the best pranksters Hogwarts had ever seen. Except maybe for the Marauders: Moony, Wormtail, Padfoot, and Prongs. They would give anything to meet these people, who were the twins' role models. Little did they know, they had already met them, and would meet them again, very soon.

"Where is it?" Fred grumbled. They were searching through Harry's trunk, by the light of their wands, because it was the middle of the night.

"What's this?" George asked, pulling out a scarlet box. The twins opened it up and pulled out the time turner Harry, Ron, and Hermione used to visit Harry's dead parents, Lily and James Potter, in the past, as well as his dead godfather, Sirius Black, and recently acquired godfather, Remus Lupin.

Fred and George didn't know this, so unwittingly turned it and went back twenty years in the past.

Fred and George looked around the room they just landed in, the Gryffendor Common Room. Fred asked, "Why are we here? We were just up in the dormitory."

George, who was reading a newspaper sitting on a table, gasped and asked, "How did we get here?"

"I don't know. What do you mean?"

"Fred, it is February 13th, 1975."

Fred's jaw dropped, then said, "Let's go explore. See who's here that we know."

They walked up to the Sixth Year Dormitories on the boy's side and heard voices, using Extendable Ears, whispering from inside, "Okay Padfoot, let's go. Moony and Wormtail will be waiting for us."

Fred and George looked at each other like Christmas had come early. Their role models and teachers were just on the other side of this door. The twins had to see them and meet them. They barged into the room, and their jaws dropped when they saw the people inside. "Harry?" Fred asked in disbelief.

"Sirius?" George asked, in the exact same manner as his brother.

"What?" The two boys asked in unison.

"He's not Harry," George pointed out, "Look at his eyes."

"He can't be Sirius either," Fred challenged, "He's younger than we are, and his eyes have life in them."

"What?" The boys asked again, "Who are you?"

"We are Fred –" Fred began.

"And George Weasley," George finished.

"Ron!" The boys exclaimed.

"Yeah, he's our younger brother," Fred said, his voice filled with disgust at the fact that the people he regarded as role models only thought of his little brother.

"So, are you from the future?" One boy asked.

"Yeah," George said simply.

"And you know Harry Potter?" The other asked hopefully.

"Of course!" Fred exclaimed.

"Who doesn't?" George said sarcastically.

"Well, you got my name right. I am Sirius Black," Sirius said.

"And I'm James Potter," James said.

"Oh my god," Fred and George said.

"So, let me get this straight," George said, "James is Prongs, Sirius is Padfoot, and Remus is Moony."

James added, "And Peter is Wormtail."

"Don't talk to us about him," Fred said through gritted teeth, "We don't like him."

"I don't want to know why," Sirius said, "And you guys are Fred and George Weasley, brothers of Ron — "

"And Bill, and Charlie," Fred interjected.

"And Ginny, and – ugh — Percy," George put in.

"And Harry and Hermione's friend," Sirius said.

"As well as the second best pranksters Hogwarts has ever seen. We are first," James said proudly.

"Well…actually," George said, "I think we tied with you, after last year."

"What happened?" Sirius asked eagerly.

"Well, our Defence Against the Dark Arts teacher was a real witch. In both ways," George said.

"Harry told us. He made that point quite clear," James said.

"So, after Dumbledore left, she was headmistress…a terrible one at that. We decided that some fun would be perfect on her first day. We set off twenty boxes of our fireworks," Fred said.

"Your fireworks?" Sirius asked skeptically.

"Yeah, we invented them. We'll show you guys some of our stuff later, we own a joke shop. Please continue George," Fred said in a 'Percy' like manner.

"It was hilarious!" George said laughing, "She spent her first day as head running around the school chasing these out-of-control fireworks. Later on, we set Nifflers in her office; they attacked her. And, finally."

"As a monument to the school we have loved so much," Fred interjected.

"As the grand finale, we set up one of our portable swamps in a corridor!" George finished.

"It was a riot!" Fred laughed.

"What did she do to you?" Sirius asked in-between laughs.

"Nothing!" Fred said. James and Sirius gawked at them.

"This is the best part!" George informed them.

"Defiantly," Fred agreed, "So, we are standing in the Entrance Hall with her, the whole school standing off in a gigantic circle around us. She says," Fred imitated Umbridge's false girly voice, "'You two are about to learn what happens to wrong-doers in my school.' I say, 'You know what, I don't think we are. George, I think we've grown out full time education.' Then George says, 'You know, I've been feeling that way myself.' And we summon our brooms from her office, because she had already given us and Harry a lifelong ban from flying, and the brooms blast two holes into her door."

George continued where his brother left off, "Fred says, 'We won't be seeing you.' And I say, 'Yeah, don't bother to keep in touch.' And, as we flew out, we tell Peeves, 'Give her hell from us!' And to everyone's amazement, including ours, he salutes us!"

"From what Harry, Ron, and Hermione told us," Fred finished off the story, "That was talked about for days, and everyone was horrible to her, but Peeves was the best."

"I'm so glad that poltergeist was brought up the right way," George said, wiping fake tears from his eyes.

James and Sirius were in hysterics by the end. "That. Was. Great!" Sirius said.

"Ron told us a little bit about you guys, but we thought you were just the below-average wanna-bes," James said.

"How do you know Harry, Ron, and Hermione anyway?" Fred asked suspiciously.

"They were here!" James exclaimed, "From the end of September to the middle of October!"

"That's where they were!" George exclaimed.

"We had so much fun!" Sirius said, but his face fell slightly, "But Hermione…well, let's just say she didn't let us do everything we planned."

Fred said sadly, "Sadly, Hermione can be like that." George nodded gravely.

"But you two are a complete different story," Sirius said slyly, "I'm sure you'd like nothing better than cause some havoc in the past Hogwarts!"

"Yeah!" Fred exclaimed.

"Duh!" George said.

"Then we'll start tomorrow at eight o'clock sharp!" James said, and Sirius, Fred, and George all saluted him.

"Where were you guys last night? Peter said that you didn't show up, and now he's in the Hospital Wing!" Remus said angrily to James and Sirius, not noticing Fred and George. It was the next morning, and Remus was talking about last night, which was full moon. Fred and George pushed their way past James and Sirius and each gave Remus a big hug. Imitating his older brother, Percy, Fred said, "Remus old chap! How lovely to see you!"

After pushing his twin aside, in the same Percy-imitation, George said, "How are you Remmy? Haven't seen you in ages! Literally!"

"Who are you?" Remus asked, trying not to sound rude.

"We are…" Fred said.

"Drumroll please!" George interrupted, and James and Sirius began to roll their tongues.

"Mr. Fred and George Weasley!" The twins said in unison.

"Do you happen to know someone named Ron?" Remus asked, surprised.

"Yeah, he's our brother," Fred said, losing all enthusiasm.

"So you're from the –" Remus started.

George cut him off, "Yes we are! And we also know Harry and Hermione."

"Don't say the 'f' word," Sirius warned, sounding as if it was a swear word.

"So, these two tell us that we are tied with them as the best pranksters Hogwarts has ever seen. Isn't that awesome?" James said quickly, changing the subject.

"Oh yes! So, what have you guys done to tie us?" Remus asked dully. He didn't really trust the twins.

"Oh, you wait Moony! It's amazing! All of the pranks they've done and they have their own joke shop line. Weasley's Wizarding Wheezes," James said proudly, "We've seen some of the stuff they've invented, it's better than Zonko's!"

This sparked Remus' interest. "So, what have you done?"

Fred and George grinned at each other mischievously. They would have never guessed that Remus Lupin was one of the infamous Marauders. He was always a good boy, and a prefect. Of course, not all prefects were good, they reminded themselves, Tom Riddle (now known as Voldemort), and their own two brothers, Bill and Ron. Ron was always getting in trouble with Harry; Bill had a fang earring, long hair in a low ponytail, and he was a curse breaker for Gringotts, the wizard bank.

"Well, there was this one time…" Fred started, and he and George spent the next forty-five minutes telling him about every prank and thing they had invented.

By the end, Remus was laughing like a maniac, as well as James and Sirius. Remus then put on a straight face, and said seriously, "You two should see Dumbledore. He most likely already knows you're here, and he'll tell you how long you can stay. Go now, otherwise I well not tolerate you staying here and I'll go to Dumbledore myself."

Fred and George glanced at each other, both thinking, 'Now this is the Remus Lupin we know.'

They obediently followed them, but left them at Dumbledore's office. They entered, explained their situation and asked what they should do.

"Well, well, well, it seems you two will need a place to stay. Not in the dormitories, seeing as you graduated last year, twenty years from now. You can go and stay in one of our guest rooms. Just go to the portrait of Merlin on the fourth floor across form the History of Magic classroom. The password is 'Nifflers.' Make yourselves at home! I'm sure Mr. Potter, Black, and Lupin already have!" Dumbledore said and the twins left the headmaster's office.
