So, I realized my Madame Prince is a bit OOC compared to the books. She's a bit nicer than she should be, but I'm gonna put that down to the fact she hasn't lived through the worst of the Marauders pranks yet. Also, according to the wiki we really have no time frame of when she took up the position of Librarian at Hogwarts, so I'm going with her having been there when the Marauders were.

By the way, I do not own Harry Potter or anything that you may recognize from another source within this story. Harry Potter is the property of the lovely J K Rowling, and I will never stop being grateful for the wonderful world and characters she created.

April 19th, 1973

Remus was undoubtedly the most studious of his group of friends. While he wasn't totally immune to moments of procrastination, he was nowhere near as bad as the other three. This meant that while Sirius and James were off setting up a prank on the fourth floor somewhere and Peter was mid wizards chess game, Remus was heading down to the Library to work on his Potions essay.

He'd be in the common room but Peter alone was distracting enough, let alone the other two when they came back laughing and on an adrenaline high from their latest mischief. He was lucky, incredibly so, to be allowed an education at all given his condition, and he wasn't about to waste it. So he'd just finish his essay as quickly as possible and then see about joining his friends.

He set his school bag down on one of the tables and got out his Potions text and a blank roll of parchment. Professor Slughorn had assigned an essay on Shrinking Solutions and so Remus flipped to that section of the book, pulled out a quill and got to work.

A while later and Remus sat back and stretched his aching hand. He had finished all but the conclusion, but when he glanced at his watch he decided he'd finish later. He had just enough time to drop off his books in the dormitory and then head down for dinner.

As he closed his Potions book and gathered his supplies, he glanced around and wasn't surprised to see that the library was much emptier than he remembered. He tended to block out the rest of the world when he was focused and while that meant he was less likely to get distracted, it also meant he tended forget the time.

His book bag made an ominous ripping sound when he slung it over his shoulder but when it did nothing else, he sighed and made for the door. If it split all the way through he could always just fix it with magic, but one could only do that so many times before the material started to become thin and tear prone and he'd already fixed a handful of rips so far. It'd actually belonged to his father when he went to Hogwarts so it did also have some sentimental value, but he'd need a new bag eventually, something his family really didn't have the money for.

A loud laugh pulled him out of his thoughts and when he glanced over he was a bit surprised to see Hadrian Moores and Lily Evans sitting with Snape and Sirius' little brother, Regulus. The four had their own homework spread out in front of them, but Hadrian was evidently in the middle of telling some sort of story given his wild hand gestures. Lily and Regulus seemed captivated by whatever he was saying, with Lily seconds away from a fit of giggles. Snape was holding his quill over his parchment, but he had a small smile on his face and would glance over every few seconds.

They made an unlikely foursome, two Gryffindors and two Slytherins but Remus wouldn't begrudge them for it. However, he knew that if either James or Sirius were here it would be a different story.

Since the fight between Sirius and Regulus that Sirius refused to talk about and the other three only knew about from the Hogwarts rumor mill, Sirius had evidently lumped Hadrian in the same category as his brother. Remus hadn't ever actually spoken to Hadrian himself, but as he looked on he couldn't picture him being the suspicious sort Sirius tried to paint him as.

James, on the other hand, didn't necessarily have anything against Regulus or Hadrian himself, but he'd side with Sirius regardless and he wouldn't be pleased to see them sitting with Snape or Lily, for completely different reasons of course.

James tried to hide it, but Remus knew that he fancied Lily. He'd get jealous anytime he saw her sitting with another boy and he had a tendency to stare at her with a dopey look on his face.

Remus quickly looked away and made for the doors when he saw Hadrian start to gather up his school work and stand. He certainly wouldn't mind a conversation with the other Gryffindor but he didn't want it to start off with Hadrian questioning why Remus had been staring at him.

The hallway was empty and Remus supposed everyone else had already headed down for dinner. He hiked up his bag a bit more and then made for the Grand Staircase. He'd only made it a handful of steps when a strange sound had Remus stopping in his tracks.

One of the only perks to being a werewolf was that he had far sharper senses than normal. His sense of smell was by far the most improved, but Remus had also found that his hearing and vision, especially at night, benefitted as well. He would also occasionally get strange feelings that made the hairs on the back of his neck rise. He supposed it was the animal instincts of the wolf, but Remus didn't like thinking about that too much. He liked to keep that part of him as separate as possible from his day to day life.

Now however, as the sound repeated itself, Remus wasn't going to try and ignore that feeling. He very slowly pulled out his wand and followed the sound around the corner to an empty classroom. As he came closer to the door he could make out what sounded like laughter in addition to the first sound, which he now realized was something repeatedly thumping against the inside of the door.

Ever so slowly Remus reached out and wrapped his hand around the nob. The metal was cool against his palm and after a moment to take a deep breath, Remus pulled it open.

It took a second for Remus to process what he was seeing, and then he dropped to his knees next to Peter, who had both his hands and feet bound together with rope. Peter opened his mouth but no sound emerged and Remus realized he'd also been magically silenced.

"Oh ho, the cavalry has arrived!" rang a voice from the other end of the room. Remus looked up, cursing himself for not paying attention, to see two older boys both dressed in green and silver. "We were wondering if anyone was going to come looking or if we'd just have to leave him here," the boy continued. He slid off of the desk he'd been perched on and stepped forward, the other boy coming up behind him.

Remus pointed his wand at them, mindful of the still bound Peter. "What did you do to him?" he said, aware that he could sound as brave as he wanted, but there wasn't a thing he could do against them. They looked to be about fifth years and no matter how advanced at Defense Against the Dark Arts Remus was, he'd be no match for them in a duel.

"Nothing permanent," the boy sneered, twirling his wand between his fingers. "We just wanted some payback for that nasty trick you brats played on us the other day."

For a moment, Remus just looked up at them uncomprehendingly before remembering quite abruptly the prank Sirius and James had convinced them to help set up. Sirius had somehow found out where the Slytherin Common Room was and they'd spelled the corridor leading up to it so that anyone who walked down it was drenched in foul smelling green ooze. The best part had been that even if the ooze was removed, the smell remained, no matter how many times you scourgify'd yourself.

Now however, Remus didn't find it near as funny as it had been when they'd returned to their dormitory, sleep deprived but drunk off of their merrymaking. They'd been so sure that no one had seen them as they set it up. With James' cloak they had only been visible for the brief moments it took to actually cast the spells, but Remus supposed it would only take a fleeting glance of red and gold for the four of them to be suspect given they already had a reputation for mischief around school.

"Looks like the jig is up," the other boy mocked, walking forward until he was a few scant feet away from Remus. "Or, I suppose we could just do the same to you."

Remus quickly pointed at the boy's chest but he only threw his head back and laughed. "You think you stand a chance against us?" he scoffed.

"Expelliarmus!"

Remus spun around, or as much as he could on his knees, and saw Hadrian, wand pointed squarely at the nearer Slytherin. The boy's wand had been flung out of his hand and when the other Slytherin raised his, the same happened to him as well. Now wandless they didn't appear nearly as confident.

"I thought the House of Slytherin was renowned for its ambition and cunning," he said, stepping around Remus and Peter. "Picking on students three years your junior doesn't display intelligence nor skill."

"Are you a first year?" the first boy asked incredulously.

Hadrian huffed a breath and then twitched his wand toward the door and Remus hurriedly dragged Peter to one side. "Yes, I am and unless you want the whole school to know that not only were you disarmed by a first year, but also tied up and left for someone to find like you were going to do to them, I'd suggest you leave."

"You expect me to believe a first year could conjure rope?"

Hadrian smiled and from what Remus could see of his face, it wasn't a particularly nice expression. "I just disarmed you, didn't I? But I'd be happy to provide you with a demonstration if that wasn't convincing enough."

There was a beat of silence where the two Slytherins glanced at each other and then, neither looking pleased with the situation, nodded slightly. Hadrian stepped to one side as they picked up their wands and strode from the room without a word.

Once their steps could no longer be heard, even by Remus, Hadrian lowered his wand from where he'd pointed it at the doorway to Peter. "Finite," he said quietly.

"Thank you!" Peter gasped immediately, squirming a bit to try and sit up. Remus helped him while Hadrian wandered over to the far end of the classroom. "I've been stuck like this for a half hour!"

"Are you alight?" Remus questioned as he tugged the rope over Peter's wrists. Peter nodded his head, still breathing deeply. Together they managed to get to rope off of Peter's ankles and Remus helped him stand.

"They didn't hurt me, just tied me up and took my wand," Peter said, leaning on Remus when he wobbled a bit.

"Speaking of which," Hadrian said, striding back across the room. In his hand he held Peter's wand, which he then held out for Peter to take.

"Thanks," Peter said gratefully, stowing it back in pocket.

"We would've been stuck in here if not for you," Remus agreed.

Hadrian had a faint dusting of pink across his cheeks. "It wasn't a big deal," he said, rubbing the back of his neck.

"Not a big deal?" Peter squawked. "You took down two fifth years Slytherins! And you're younger than us!"

Hadrian shifted a bit, looking faintly uncomfortable though the pink didn't fade. He opened his mouth, but couldn't seem to think of anything to say and shrugged instead.

The three stood quietly for several seconds before Hadrian cleared his throat. "We'd best hurry if we don't want to miss dinner." Remus and Peter nodded and followed him out of the room. "See you later," he said, picking up his book bag from the floor.

"Thanks again!" Peter called to his retreating back. The two then slowly made their way to the Grand Staircase. It took until the fifth floor before Peter could walk normally and Remus vaguely wondered if they should have gone to the Hospital Wing to make sure his circulation hadn't been cut off. They were almost to the Fat Lady when Peter spoke up.

"I don't know what he did to Sirius, but Hadrian doesn't seem too bad," he said quietly.

Remus nodded, but didn't reply because just then the portrait sung open to emit a grinning Sirius and James, obviously just back from another successful prank.

"Where've you two been?" James said, running a hand through his hair.

Remus glanced down at Peter and they locked eyes for a second. "Nowhere," they replied together.
