Chapter 1

"GRYFFINDOR!" The entire hall erupted in applause and young Sirius Black wore a grin on his face as he happily walked over the table of Gryffindor house. Yet inside, all he could think of was how disappointed his parents would be that he didn't get into Slytherin house.

James Potter and Remus Lupin, two friends that Sirius had made on the way to Hogwarts, had already been sorted into Gryffindor and high-fives him when he approached them at the table.

"I knew you'd be Gryffindor!" Said James.

Sirius' smile dropped to a frown and the other two boys asked him what was wrong but he didn't say, preferring not to burden them with his problems.

Instead, he assured them that there was nothing wrong and the three of them welcomed a new friend to the table, a plump little boy called Peter Pettigrew. James took pity on the poor boy and said to the other two to be kind and be friends with him.

The four boys then began eating the great feast before them, completely amazed by the amount of options.

James made conversation with a little red-headed girl called Lily Evans. It wouldn't take a genius to guess that he had a crush on her.


"I'm so full, I could pass out. And-and go into a food coma!" James groaned as he layed on the common room couch, his stomach filled to the brim with chicken and mashed potatoes.

"I told you not to eat that much." Sirius snickered whilst sitting next to his new friend.

"I told you! I don't listen to reason!" James retorted. "It's in my blood!"

Remus sighed and shook his head, thinking,
My new friends are weird. But I'll take it. They're funny.

"Sleep it off." Remus laughed.

Remus then felt a sharp pain in his head, and he ran out of the common room, leaving the other boys confused.

"We can't get periods can we?" Asked Sirius, a serious look on his face; his question was genuine.


Peter bursted out laughing and James let out a small chuckle, clutching his stomach shortly after.

"Don't make me laugh, it hurts!" He exclaimed. Sirius laughed, causing both the other boys to laugh again, filling the Gryffindor common room with the sound of pure laughter.

A few minutes later, Peter helped James to their shared dorm room while Sirius trailed behind, laughing at his friend's distress.


Sirius pointed his wand at his robes, furiously waving it around as he tried to turn his robes green.

"COME ON! WORK!" He shouted. Sirius clapped a hand over his mouth and layed flat on the floor, hoping that Peter and James wouldn't see him.

"Y'know, the beds are comfier than the floor, Sirius."

"Yes. I- I'm aware of that. I was- go back to sleep, James."

James was stubborn. He wasn't going to go back to sleep until he found out what was wrong.

He got up from his bed and sat on the floor next to Sirius, crossing his arms and legs.

"What- what're you doing?" Asked Sirius.

"What's wrong? You're upset."

Sirius stood up and sighed. "If my parents found out I was sorted into Gryffindor, they'd lose their heads. So I'm trying to turn my robes green."

James stood up and reached for his wand.

"What's the spell?"


"What's the spell?"


"Multicorfors. Okay." James pointed his wand at his friends robes and said the incantation. "Multicorfors."

The bottom of the crimson red began to turn into a green.

Peter joined in too, and the three boys eventually succeeded in turning his robes green.

"Okay. Now we'll get you to the dungeons. I saw a prefect take the Slytherins down some stairs. If we follow the stairs, maybe we'll find it!" James suggested.

Peter nodded and Sirius thanked the two for helping him.

"But how are we going to get there? What if someone sees us?"

James chuckled and assured his friend. "I'm prepared."

He then reached under his bed and pulled out an old cloak.

Sirius' face went blank. "Because no one is going to see a big cloak moving around the castle."

"You are so clueless." said James. "This is an invisibility cloak. If the three of us get under it, no one will see us."

"That's genius!"

"I know." James wore a smug look. "Now come on, we need to sneak you in there and come back before anyone notices we're gone."

The boys got under the cloak and snuck out of the Gryffindor tower and were almost at the staircase leading to the dungeons when they heard footsteps, causing them to stop in their tracks.

They saw their friend Remus, his clothes torn slightly and he was looking extremely tired and worn out.

"What happened to him?" James whispered.

Sirius shrugged. "Do you even talk, Peter?"

"Yes." The plump boy squeaked. "I do."

James grabbed Remus' arm and pulled him under the cloak.

"What the- who's there? Let go of me!" Remus struggled before catching sight of the three boys. "What're you guys doing!?"

"Sneaking Sirius into the Slytherin dungeons."

"Oh. Why?" Remus asked, tilting his head to the side slightly in mere confusion.

After explaining Sirius' situation to Remus, he simply nodded and helped them navigate their way to the dungeons; the young boy knew his way around the castle after only seven hours of being inside it.

"This is your stop."

"Thanks guys, I appreciate it."

"Good luck Sirius!" James tried to force a smile, he had only just made a new friend and he already had to lose him.

Sirius went inside the Slytherin common room and ran back out seconds later.

"Actually, you guys have been so nice to me. And Slytherins are known for being mean so who cares what my parents say? I'm staying with you guys! Wait, where are you?" The boy looked around, not being able to spot his friends anywhere.

The boys emerged from the cloak and brought Sirius in for a group hug.

"Are we best friends now?"


The boys went back to their dorm and collapsed into the floor, falling asleep almost instantly.

Sirius was grateful for his new, kind friends; they were unlike anyone he had ever known throughout his entire life.

Remus was worried someone would find out about his condition; his lycanthropy was something he had to hide in order to be accepted in society.

Peter was happy to be part of a group; he was always neglected by the other kids.

And James was thinking of ways to prank Remus, Sirius and Peter; he was a happy child who was full of mischief.
