A/N: Welcome to quite probably the least planned out story I have ever written! This is, as the description suggests, a collection of different time travel stories featuring characters and times in the Harry Potter universe. As of the moment of my writing this, I have seven stories currently planned. All of them are barely more than concepts. The current plan is to finish each story before moving on to the next, though I suppose if you wanted I could try to write them all simultaneously; that would probably get confusing. Each story will likely take between three and four chapters, depending on how much happens, but I also kind of just made up that number cause like I said, these really aren't planned.

A few brief things about these stories:

a) The past isn't going to change, it's not one of those "redo everything" fics.

b) The Next Gen characters who show up (will any show up?) will be approximately the way they are in my fanfic "Tales From the Diaries." You definitely don't have to read that fic to understand this one, but that's where the ages and houses are coming from.

c) Harry Potter and the Cursed Child is not considered canon. Period. Nothing from that book will show up in my fanfiction.

If any of this is a problem for you, you have been warned, and you may stop reading here.

So, without further ado...

ADVENTURES IN TIME TRAVEL, PART ONE: AFTER THE WAR

Chapter One: Happy Birthday?

May 2, 2018, just after midnight

"...Happy Birthday to you!"

"Thanks, you lot," said Victoire, a faint smile starting to form on her lips. "I appreciate it."

"Well, we thought you deserved a birthday celebration," Dom said, grinning. "Only the best for my sister."

"We love you, sis," said Louis.

"We all do," added Molly. "You're one of my two favorite older cousins."

Victoire chuckled. "Gee, thanks."

"I made the mini fireworks, you know," James said.

"I helped!" Fred added.

"Basically," said Rose, "We all helped because we wanted you to have a good birthday."

"Because you're great," Albus added.

She smiled again. "Well, you all did a great job."

"But you're still not happy," Dom said. It wasn't a question.

"You know I hate my birthday. Always have." She had always had her birthday parties some time closer to the middle of May, growing up, but her family had always tried to do something small on her actual birthday, and it had always been a miserable experience. Everyone would be sad. Uncle George never came. It had grown into one of the worst days of the year for her. But people still tried to celebrate. It wasn't just for her; they were trying to make something positive happen on what was a terrible day. But it had really made her dislike her birthday.

"At least you get to have a birthday on the day Voldemort died," said Rose, always the one for the positive spin.

"Yeah," said Victoire. "Him and everyone else. It's so strange with Teddy... I mean, he sent me a letter today that said 'Happy Birthday.' Just those words. Happy Birthday, from my boyfriend, on the day his parents died."

"Oh, so we are using the b-word now?" Molly asked, raising her eyebrows.

Victoire rolled her eyes. "Yes, we made it official over the Christmas holidays, years of just sneaking off together to go have secret chats and also snog a little bit were getting a bit ridiculous. But we decided not to tell anyone unless they asked because we're tired of people prying."

"Well, now we have to know everything," said Dom.

"Maybe not everything," said Fred.

"Yeah, leave out the gross bits," said Louis.

"Alright, that's enough. All of you, get to bed. It is past curfew time and as your Head Girl I can not condone you being out of your house dormitories at this late hour."

"I'm in my house dormitory," said Albus.

"Right, you're fine. The rest of you, thank you again, I love you, goodnight."

"Night, Vic," they chorused, leaving the dormitory.

She shook her head and went to bed, drifting off into a strange and dreamless sleep.

When she woke up in the morning, something was off. Her dormitory was empty. Why was that? Had she overslept? She hoped not; she had a lot of work to get done today. She frowned as she went to get dressed, then gasped when she realized it wasn't her things under the bed. What was going on?! Had someone pulled a prank of some kind and switched people's things around? She was definitely in the same bed. Shaking her head, she looked around, but her things were nowhere to be found, and none of these things looked like those of her doormmates, either. She walked out into the common room, which was also empty. Something wasn't right here. She walked outside to the hallway, and nearly had a heart attack. The hallway was filled with rubble and dust, and large chunks of the wall appeared to be blown out, like there had been multiple small explosions. Had James set off more of his mini fireworks? It didn't seem like something he would do. She walked down the hallway and saw that the debris and damage continued. What was going on? What had happened overnight, and how had it not woken her? The staircase up to the first floor was also covered in debris, and what appeared to be blood. Her heart raced. What was happening? On her way up the staircase, two girls who looked her age ran down it past her. One of them shot her an odd look. She kept walking, past more and more damage, and passed a boy who also looked around her age. "What happened?" she asked.

"What happened?" The boy gave her a dumbfounded look. "What are you, an idiot? What do you mean, what happened? To the school? Battles aren't won with no damage." He kept walking, and Victoire frowned. Battles? What did he mean, battles? And suddenly a horrible thought began to rise in her head, a horrible, impossible thought.

She kept walking, past a few more people, until she reached the entrance hall. As soon as she looked into the Great Hall, she knew her fear had been correct. It was full of people. Many of them were injured. And in the distance, she thought she made out a line of bodies. She had traveled back in time. She didn't have a clue how, but somehow, she had gone back exactly twenty years. It was still May 2, but now it was the May 2. May 2, 1998. The day that would haunt all of her adult family members for the rest of their lives.

No sooner had she thought this then a girl around her age walked out of the Great Hall. She was around her age now, but her features were unmistakable. "Hermione," she said, without thinking.

Her eighteen-year-old aunt looked up. "Yes, that's me." She frowned. "You look like someone I know... but a little bit different."

"I would imagine so," said Victoire. She did look like her mother. "Are, uh, are the Weasleys in there?"

Hermione looked at the room behind her, then back at Victoire. "Whether they are or not, they're really not looking to be bothered right now."

"I know," said Victoire. As horrible as Fred's death was for everyone in the future, she knew it was worse at this time. "But something's happened to me, something I don't understand, and I need to know what is going on and how to fix it."

"And you think they can help you?" Hermione asked, her eyes narrowed.

"Yes."

"Why?"

She didn't know if it was safe to say that she was from the future or who she was. But then, how could her family help her if she didn't tell them? "I've time traveled from the future."

Hermione raised her eyebrows. "All the time turners were destroyed years ago."

"No time turner was involved here," Victoire said. "And those only traveled back a few hours, anyway."

Hermione's eyes widened. "How far in the future are you from?"

Victoire swallowed. "Twenty years."

"Twenty years?" Hermione looked shocked, intrigued, and suspicious. "That's never happened."

"I know."

"And it still doesn't quite explain why you think the Weasleys can help you."

"You're very smart, I think you already figured it out."

Hermione looked at her for a second, then nodded slowly. "It's Fleur you look like. You're her and Bill's daughter, aren't you?"

Victoire nodded. "Victoire Weasley."

Hermione took a deep breath. "Alright. I'll take you to where they are. But if you really are a Weasley from the future, then I'm sure you know what happened here tonight."

"Yes," said Victoire. "I do. And I wish I didn't have to do this, but I don't know who else to ask for help than my family."

Hermione nodded. "Come with me, then."
