A/N: Hey guys! So, have you heard of The Librarians? I never have, until I watched the first two episodes of the show and it was AMAZING! Utterly fantastic. So, putting my favorite HP characters into play, namely the Golden Trio, Remus, and Sirius (Sorry Ginny fans-there won't really be any Ginny in this fic!) they become the Librarians-in-Training! Or at least Harry, Ron, and Hermione, (plus Crookshanks-he's the Library cat) are the LITs, and Sirius is the Guardian. (Also, Sirius and Remus are in a relationship. Mostly long distance.)

Remus has control of his transformations and can transform whenever he pleases.

This is post-DH. Fred isn't dead, Sirius got his name cleared, Remus was never romantically involved with Tonks, Dumbledore is dead but is the past Librarian, and he past the Library down to Remus when he ended school. Only Sirius knew about it, because he was dating Sirius at the time. This is an AU story, assuming they went back to Hogwarts to finish their education. They also get additional powers from being LITs.

Let's start, now. I present to you: THE LIBRARIANS!

"REMUS, YOU'RE KEEPING a secret from us," Hermione said over breakfast. The Golden Trio, along with Crookshanks and Sirius, were living in the Lupin household, a place that was Remus' and had been bought by the werewolf and Sirius. Sirius himself had been cleared, and gleefully gotten rid of Number 12, Grimmauld Place… well , more like replaced it with this big place, this bright airy mansion, in a different layout then before. It was their's… all their's. And the three teens known as the Golden Trio who had saved the world had helped, and on their insistence moved in with the remaining two Marauders.

Sirius was now the DADA professor, and Remus was a librarian.

They had all changed since the war. Remus had become his mischievous self again, and Sirius and himself had began pranking the GT. They had also revealed to the Golden Trio of their relationship (or at least their romantic relationship in the past, starting in their fourth year and then continuing it up until the point of Halloween 1981) and Hermione had jumpstarted it back up again by putting them under the Imperius Curse and making them kiss each other. And once they were kissing and Hermione released them, they finally admitted defeat and got back together.

Hermione and Harry had also changed their clothing styles. Harry was now officially a hipster. He wore beanies, skinny jeans, boots, suspenders, and bow ties. He switched his accessories up every day, but the only thing he wore all the time were his dark green converses. He had drawn a 3D black lightning bolt, coloring it in, in honor of what he and his friends had done. He always kept his glasses.

Right now he was wearing a black beanie, a white dress shirt, a dark grey vest that was buttoned up beginning at below his nipples, black skinny jeans, and his ever present converses. He also had a dark green velvet bowtie.

Hermione had begun to wear skirts and dresses more. Before, she was all jeans and hoodies, but now she was a stylish bookworm. She was wearing a teal and white leopard print sweater over a white polo shirt, a white skirt that went to just above her knees, a thin belt over the skirt, maroon tights, and black lace up ankle length boots. Her hair was, as usual, in loose caramel colored ringlets that touched her shoulders.

Hermione was right, Remus was hiding something. The scarred werewolf smiled and tied his shoulder blade dark blond long hair back. "Yes, you are right, Hermione, I am hiding something. Do you want to help the world out again?"

Harry's head whipped up, his messy black hair moving and his sparkling emerald green eyes focused on Remus. "Yes!" Harry said. "What does this involve?"

"Even better, what are the foods like?" Ron asked, "I'm looking for a new adventure."

"So we are," Hermione said, grinning, and turned back to Remus. "What is it, Moony?"

"Magic," Remus said, "a different kind of magic. It's ancient magic, in artifacts. I am the Librarian." At the 17-year-olds blank looks, he took some letters from under the table and handed it to each of them.

The Golden Trio and Sirius looked at the letters. It was written in slanted, glowing script that wasn't Remus'. Harry opened his letter first, being presented with a blank piece of paper at first. Then words started appearing on the page, glowing emerald green:

Harry James Potter,

You have been selected to

be one of three

Librarians-In-Training.

Go to the Applechance library and show Cho Chang the letter.

Good Luck!

The Library

Ron's and Hermione's letters basically read the same thing, except for Sirius' which read:

Sirius Black the Third (Also Known As Padfoot)

You have been selected to

be the Guardian to the

Librarians-In-Training and

the current Librarian, Remus John Lupin.

Go to the Applechance library and show Cho Chang the letter.

Good Luck!

The Library

Remus added, "Let's Apparate."

The five Apparated, and landed behind the wall of a library. It was the Applechance Library, just like in the letters. It was a small library however. Remus walked towards the front door and the 4 followed him. The front desk was inhabited by a young Asian woman. "Hello, Remus, Sirius, Harry, Ron, Hermione."

She was wearing a white blouse that had a collar and was buttoned beginning at her collarbone, and the sleeves were pushed up to above her elbows. She also had on a black pencil skirt and black heels. She walked out from behind the desk, smiling. "They've gotten the letters, Remus?"

"They have," The werewolf said, smiling. A black cat with blue eyes came from behind the desk, jumping on Cho's head.

"Hello, Slick," Remus said.

"Hi Remus," The cat said, its tail flicking. The GT looked at the cat in shock. "What? Have you never seen a talking cat?"

"No!" Hermione said, shaking her head, "this defies all logic, even magical logic… I want to see more, I need to see more. Let's go to the Library!" She was now bouncing on her heels and looked around. Cho tapped over to a library bookshelf and put her fingers on a book, tilting it from the bookshelf. The shelf opened.

"This is more about magical artifacts then anything," Remus warned them as the door opened to reveal an elevator. They all stepped inside it, and Cho pressed the button for L. L for Library.

Finally they reached the library and Hermione was out first, rushing down the stairs. On either side of the stairs were gold lions, and on the back of the golden lions were bronze eagles, black badgers, and around the necks of the lions, silver serpents. The Golden Trio gasped when they saw the Library.

"Th-this is the Library?" Ron gasped out.

"It's AMAZING!" Hermione gushed, running forward, her skirt swishing. "The pure amount of information and knowledge!"

"And the art!" Harry agreed, his eyes wide behind his glasses. "The artifacts, the history! Even so called regular artifacts!" He rushed forward as well, dragging Ron along with him. Remus, Sirius, Cho, and Slick stood at the steps of the Library, the cat around Cho's shoulders.

"This is where you work?" Sirius asked. Remus smiled, nodding, and he walked down the steps, Sirius following him. Cho and Slick went back upstairs, to the regular non-magical library. The Golden Trio was currently exploring the Library.

"Guys, come here for a second," Remus called. The Golden Trio slowly and reluctantly made their way to Remus and followed him to the right wall, where many doors were. But there were two adjoining glass doors with intricate patterns on them. Remus pushed the doors open.

The Golden Trio gasped. There were shiny wooden floors, and there looked to be a compass in the middle. There was a long table over the compass, and there were bookshelves to the left, lined up neatly. There were a round table and two chairs in the middle of the shelves, and a staircase that spiraled upwards on the right side. To the left were 2 doors. There was a wall that encompassed the stairs, and against the wall was a bookshelf of fictional books. The staircase led up to another level that was encased by glass supports, and there were more bookshelves on the left side. In the mini hallway there was a doorway. There was a book on a pedestal on the first floor that was by the first bookshelf.

"This… is the Annex," Remus said, as the Golden trio looked around in amazement. "This is my main workspace, and where I live sometimes. Speaking of which, our first mission is to get the Crown of King Arthur. I can't do it alone… ready?"
