Hi, this is my 3,928,374th Albus Severus Potter story, I think I have a problem. Anyway, I don't think I've done one anything like this before and I'm kinda anxious to see how it plays out. You guys always seem to enjoy these, so let's get started, shall we?

This is a cast listing of all my characters:

Ella: Maia Mitchell
Alexia: Gigi Hadid
Sev: Logan Lerman
Scorpius: Bertie Gilbert
Austyn: Ariana Grande
Bryn: Jamie Blackley

PARTY IN THE ROOM OF REQUIREMENT

FRIDAY

MIDNIGHT TO DAYBREAK

I charmed the last flyer onto the wall before disappearing into an alcove as the prefects made their rounds. Luckily, I was an absolute master of charms and made the flyers invisible until tomorrow and next to impossible to remove, painful boils would cover anyone who tried to spell them off. They would also hide themselves from the professors and evaporate after classes were finished Friday. The last thing I needed was for the party to be a bust before it even happened. I did have a legacy to keep up after all.

Once the coast was clear, I slipped out of the alcove and stuck to the shadows until I found the secret passage back to the dungeons. The passage was on a thing called the Marauder's Map, a map of all the secret parts of campus handed down to James Potter from his father. He and my big brother Stef were best friend from the first time they met. He passed the knowledge down to me; the two of us were always really close even if I was a year younger.

The only person in the common room was my best friend Alexia and she was asleep on one of the couches. I smirked and immediately hatched a plan to prank her. It was always an adventure being my friend and she knew but stayed anyway. Most of the time she wasn't the target of the pranks, but sometimes she made the opportunity impossible to avoid.

I knew better than to do something permanent, I would never hear the end of it. Even knowing about her vanity, I quietly muttered a spell under my voice to turn her hair green temporarily. I wasn't bragging when I said I was good at charms, she wouldn't be able to reverse it without my help. I also knew she wouldn't look at her hair until tomorrow morning and it made the prank even sweeter. Part of being a prankster was knowing your targets.

"Lexi, I'm back," I whispered, shaking her shoulders and watching her slowly wake up. "The flyers are in place, the party's going to be the talk of the castle for years to come."

She just muttered under her breath and headed to the staircase without looking to see if I was following her. She was my backup in case the secret passage was blocked hence why she was in the common room at 3 am. Sometimes the portraits liked to play pranks of their own and block some of the secret passages, it was appreciated but annoying at the same time, and ignore people when they asked for entrance. It was always good to have a second option.

The next morning Alexia's screams were my alarm and it made me laugh. The other girls groaned and sat up groggily, glaring over at me. I guess they'd shared a dorm with me long enough to know it was my fault when she screamed most of the time.

"Morgana Eleanor!"

She used my full name, I must've really upset her. I still couldn't wipe the smirk off my face as I got out of bed and went into the bathroom to assess the damage. She was standing in front of one of the mirrors with a towel around her body and a pissed expression on her face.

"Reverse it this instant!" she shrieked, holding out a lock of seaweed-colored hair. "I know it was you and I know I can't reverse it without making it worse!"

"I thought you said you could pull off any look, Lexi?" I mused, leaning back against the doorframe with my arms crossed over my chest. "Does that not include green hair? What about your inner Slytherin?"

"I'm not kidding, Ella. Reverse this right now," she whined, even stomping her foot for emphasis. "I can't very well expect Arthur Bigins to ask me to the party looking like I just spontaneously grew legs and escaped from the Black Lake!"

"If he doesn't love you at your Poison Ivy, he doesn't deserve you at you Storm," I quipped back, making a Muggle reference I knew she wouldn't get.

She turned around and glared at me with her hands on her hips. If I didn't change it back, I would have to deal with her complaining for the rest of the day. Today was supposed to be filled with people trying to figure out who planned the party and me putting said party together. I didn't have time for her to be pissed, she had to help me.

I went back to my bed and grabbed my wand before reluctantly changing her hair back. The color stayed pretty bright over night; I was getting better at charms. That meant my flyers were going to be almost undetectable by anyone other than students. An excited shiver coursed up my spine: this party was going to be so much fun!

"You're going to help me get the Room ready for tomorrow night, right?" I asked as I watched her do her makeup.

"Do I have a choice?" she retorted, saying the spell to keep it in place. "I basically agreed to help you do everything when we became best friends first year, even the crazy things that land us in detention."

She was being dramatic, we'd only had detention a handful of times. For all the pranks I did, I almost never got caught. My big brother, James Potter, and Freddie Weasley always took most of the heat so I could go undetected. Now that they'd all graduated, the burden fell to me and I was prepared to carry it. I was a seventh year after all, it was my job to keep Hogwarts interesting.

"Maybe old Art likes bad girls, Lex?" I suggested as I headed to the showers. "Just something to think about!"

Alexia was the conscience I often times ignored. I did whatever I wanted most of the time without thinking of the consequences. Drank too much, did too many pranks, and missed too much class. With all that being said, she still had my back no matter what happened and I had hers. She even let me borrow her notes when I wasn't in class, a perk of having the exact same schedule. Just like best mates were supposed to do.

The party tomorrow night was the talk of the Great Hall at breakfast that morning. I couldn't wipe the smug smirk off my lips because of it. People were almost as excited about my party as they were for my brother's. I couldn't wait to write him after Saturday and tell him how well it went.

Just as I was thinking that, the owls flew overhead and dropped our post onto the breakfast plates. I had a letter from Stef and a postcard from my Gram. She didn't quite understand how the post worked so she always sent things to mum and then Stef sent them to me. It was the perk of having a wizard brother in an otherwise muggle family. Slytherin had become far more accepting since the Great War, or maybe I was just too manipulative to go into any other house…

Ella,

I've heard from my sources you've placed flyers around school that can't be seen by professors and are immovable from the walls. I'm very impressed, that's some next level charms, little sister. I guess you're going to fill my shoes just fine, even if you were the one that always charmed my things –but that's not the point.

There are ulterior motives for this letter, I regret to inform you. James, Freddie, and I were having a pint the other day and he told me about his little brother's misguided affections for a certain brunette with a secret septum piercing. Sound familiar?

Sev Potter thinks you're the hottest thing next to Firewhisky, little sister. Imagine if you got married! I'd be related to my best mate and my sister would be a freakin' Potter. How sick would that be?!

Right, I got a bit off topic. It's very important that you get Sev to come to your party and open up more. He's too reserved right now and that's not how anyone needs to spend their last year at Hogwarts; you've got to get drunk at least once. As for how you're going to get Head Boy, never done a thing wrong Sev Potter to go to your unapproved soiree, I'm not sure. But something tells me you can use your feminine wiles to get just about anything.

Your loving and very impressed brother,

Stef

"So I take it by the smile on your face Stef approves of your party?" Austyn said, sitting down across from me and Alexia at the table.

"So you've seen the flyers? Are you impressed?"

"I thought Stef snuck back in and did it for a second, then I remembered he couldn't charm his way out of a wet paper sack and knew you'd done it. Color me impressed," she said, winking saucily at me. "I've got your alcohol covered, doll."

Her dad owned a Firewhisky distillery and she had access to as much alcohol as she wanted at the legal age of seventeen. Stef also taught me it was all about who you know, the more connections the easier it was to pull things off AND get away with them. Granted, Austyn was my friend before I knew about her father, but it was helpful sometimes.

"You're a peach, Aus," I complimented, spooning gravy onto my plate. "Guess what ingenious knowledge my boisterous brother just bestowed upon me?"

"Some sick alliteration?" Bryn said, sitting by Austyn and finishing off our group.

He played Quidditch with my brother and took my virginity fifth year. Granted, Stef didn't know about the latter and I had no plans on telling him in the immediate future. Big brothers didn't like to know that their mates deflowered their younger sisters…or so I'd heard. Even if Bryn was more my mate than his, he'd probably take it seriously and try to beat him up or something else masculine of the sort.

"He told me Sev Potter fancies me and said I have to make sure he comes to the party tomorrow," I replied after I stuck my tongue out at Bryn teasingly. "It's apparently an Azkaban-worthy crime to let him leave Hogwarts without getting drunk at least once, or so our brothers think."

"Sev Potter fancies you?" Alexia exclaimed dramatically. "He never leaves the library. Has the poor thing ever even seen you? Do you even know where the library is?"

I maneuvered my wand through the air and caused her to drop her eggs onto her lap instead of in her mouth. When she glared at me, I just smiled patronizingly at her and winked for extra effect. She couldn't complain because she'd deserved it.

"It makes sense. Don't the boring, shy boys always love the wild girls?" Austyn asked, taking more bacon from the tray between us. "He's pretty cute, for a guy who doesn't really talk, I mean."

I just nodded and started thinking about the way to get him to the party. Stef was right, everyone needed to party at least once before they left Hogwarts. It would be criminal if I let the poor boy rot in the library for the rest of the year, right?
