I Solemnly Swear

By headsfullofstars

Summary: Harry travels back in time to the Marauders Era in hope to save countless lives from Voldemort. He goes by the name 'Harry Turner', and attends Hogwarts in the 1970s. Hopefully a good read in spite of the probably generic plot line.

Disclaimer: I would like to state that I am only a thirteen year old girl and that despite I wish they were, no characters are mine besides 'Harry Turner' himself. The story is all mine, however.

Chapter 3

The First Day

Harry woke quite abruptly the next morning to the sounds of laughter. He jumped up, startled, and chortled when he saw all boys surrounding a fairly aggravated looking Sirius.

"Go away Peter, or I swear to Merlin.." Sirius growled as Peter hit him round the head with a pillow. The intention of the words was to scare the boys away, though Sirius' bedhead and serious face just made the others laugh even more. "It's not funny!" He barked.

"Sirius, get up." James laughed, throwing another pillow in Sirius' direction. The miffed boy grabbed the pillow and flung it across the room, scowling at the boys, who were quite frankly having a laughing fit.

"Bloody hell." Sirius groaned, causing a laugh to erupt from Harry's mouth. All boys turned to look at the half-asleep boy and smirked.

"See? Even Harry's up." Remus said, gesturing to Harry as Peter pulled off a look that screamed 'Merlin help us', though he too was clutching his stomach as he laughed.

"Sirius, we're going to miss breakfast!" Peter said, frowning as a loud stomach-grumbling noise filled the room.

"And we're getting our class schedules this morning!" Remus reminded them cheerfully.

"Well, if I don't have a schedule that means I can skip class, so I'd rather stay in bed thank you very much." Sirius said with a mock smile, before slamming his head against his pillow and hiding under the covers.

"You'll get your schedule at some point." Remus said with a frown.

"Yeah, they won't let you off that easily." Harry laughed as he clambered out of his bed.

"Ugh!" Sirius groaned dramatically as he jumped out of bed with an irritated expression.

"About time!" James said, rolling his eyes.

"How long do we have?" Sirius asked as he entered the bathroom.

"10 minutes?" James said. Sirius spun on his heel to face the boys, his eyebrows raised.

"Your joking?"

"Nope, I'm being serious." James smirked. Sirius glared at the boy, a fake laugh escaping his lips as the other boys erupted into a fit of laughter, before turning to face the mirror.

"How am I going to do my hair in 10 minutes?" He groaned, combing through his hair.

"Well, if you had gotten up when we told you too, you would have had half an hour to do your hair." Remus said, rolling his eyes in a mock-like way.

"If every mornings going to be like this then Merlin help us." Harry said as he threw on his robes.

After around 20 minutes, the boys stammered out of the common room, racing the get to the Great Hall before classes started. They were ten minutes later than they had planned to be as a result of Sirius' insisting that he couldn't possibly leave the common room without his hair absolutely flawless. The Great Hall was a festival of sights and smells as they entered, the smell of freshly cooked breakfast wafting around them. All boys rushed over to the Gryffindor table and seated together on the end of the row.

"When does mail come?" Sirius asked curiously as he helped himself to some food.

"Either today or tomorrow, I'm guessing." James said around a piece of toast, as he shrugged.

All boys watched attentively as a Gryffindor prefect sporting red and gold made their way down the table, handing out class schedules. Remus snatched eagerly at his whilst the other boys took theirs reluctantly.

"Double History of Magic first, with Slytherin? Are they serious?" James groaned, looking down at his schedule with hostility.

"No, but I am Sirius." Sirius laughed, causing a fit of laughter throughout the five boys. Peter spat out the pumpkin juice he had been enjoying all over the table and began cracking up laughing, which only caused the volume of laughter to double.

"You.. did not... just.. say that!" James breathed in between laughs.

Soon the breakfast food began to disappear and the Great Hall began to empty as students filtered out towards their classes. The five boys gathered their bags and began to make their way towards the History of Magic classroom.

"Bugger." Sirius said as they reached another dead end.

"We need to hurry up, we're going to be late." Harry said, looking around desperately.

They all sighed in relief as they finally arrived at the door of Professor Binns' classroom.

"This should be good, I love History." Sirius said, an excited expression plastered across his face. They all entered the classroom and were alleviated to find that the professor hadn't actually arrived to the lesson next. All boys quickly made their ways over to the remaining unoccupied tables. Remus and Peter seated into the front table, while James and Harry seated into the table behind. They smiled apologetically up at Sirius, who shrugged it off and searched the room for an empty seat. The class was already so full that there was only one seat left - the one behind James and Harry, besides.. her. Well that's just bloody fantastic. She probably loathes me like her sisters, too. He thought to himself as he walked hesitantly towards the table.

"Hi." Narcissa almost whispered as Sirius seated himself, which earned her a surprised expression from her cousin. "What? Just because your in Gryffindor doesn't mean I can't talk to you." The blonde said, twirling a strand of her hair around her fingers; it was a childhood habit of Narcissa's, one she usually did when she was nervous. Her hair was tied up elegantly in a half-up half-down, with a dark green ribbon that was tied in a bow.

"Your sisters don't seem to think that." Sirius said with a shrug, looking through his bag for a piece of plain parchment. Narcissa opened her mouth to speak, but quickly closed it again as the door at the front of the class opened, and a ghost walked out.

"Hello, class. I'm Professor Binns and I will be your History of Magic teacher." The ghost said, eyeing the students carefully. He then launched into a full introduction to what they would be learning about that year. Not once did he crack a joke, or even a smile. He was, decidedly, a very boring man - well, ghost.

"...So I want you all to pair up with the person sitting next to you, and discuss how many events you already know of before we get started."

Professor Binns stalked over and sat at his desk. A low murmur broke out in the room of people discussing events in wizard history that they knew off. Sirius and Narcissa, however, sat in complete silence.

"Damn it Sirius, why are you ignoring me?" Narcissa cried, her face a scowl as she stared at Sirius, who was a little startled by the sudden outburst.

"Well, technically, you weren't talking either, which means we were both ignoring eachother." Sirius said matter-of-factly.

"So that's how it's going to be?" Narcissa asked, frowning at Sirius.

"Yes, that's exactly how it's going to be, seeing as you probably despise me just like your sisters." Sirius growled.

"It's not my fault you betrayed our family and chose Gryffindor!" Narcissa snarled, biting her tongue as she instantly regretted the words that slipped out of her mouth. Sirius glared at her for a moment, before turning his back to her and scrawling notes down onto his parchment.

"Sirius.. wait-"

"No, Narcissa." Sirius barked, not even turning to face her. Narcissa sighed exasperatedly, before turning her back to Sirius' and writing notes onto her own parchment. Sirius swore he could see tears in her eyes as he turned to face her, but brushed it off immediately, deciding he didn't care how she felt. He didn't exactly feel up to confiding in her after her sudden outburst.

"I hate History." Sirius groaned as the five boys exited the classroom.

"So much for loving History then." James laughed. Sirius sighed disappointedly.

"Hey, what's up?" James asked, craning his neck to face his visibly upset companion.

"Nothing." Sirius lied.

"What were you and that girl arguing about?" Peter asked, tilting his head slightly.

"What girl?"

"The blonde one, the one you were sat next to."

"Narcissa? Oh, it's nothing."

"She's your cousin, right?" Harry asked curiously.

"Yeah." Sirius sighed.

"Maybe you should talk to her." Remus said.

"Yeah, like that would go well; hey, Narcissa, look I know everyone in our family like hates me right now, including you, but do you want to talk?" Sirius said sarcastically, a wry smile on his face.

"Oh come on mate, it can't be that bad." James said tiredly.

"Look, I'll talk to her if you want me to." Harry said.

"Yeah, good luck with that." Sirius said, rolling his eyes. "She's the most stubborn girl I've ever known."

"She can't be that bad." Harry said with a smile.

"Oh, but she can." Sirius said, a slight smirk on his face. "She's a Black, of course she can."

A/N: Yes I know, this chapter is shorter compared to the others, but there really wasn't that much to include. I promise the next one will be longer, and a lot more interesting.
