Mwahahahaha! I'm sorry for the cliffy at the end of the last chapter, I couldn't help myself! It just had to be done! Yet again, I am making this up as I write so this'll be interesting.

Usual disclaimer, not getting any money, don't own Harry Potter, not a millionaire, just a high school student with too much imagination and more than a touch of insanity.

As soon as the hat shouted out Slytherin, Harry had passed the hat over to a shell-shocked McGonagall and calmly made his way over to take a seat beside Draco at the Slytherin table. As soon as he was seated he smiled at Fred, George and Tom while sending out a mental cheer of

'Mission successful! We now have at least one member in every house. Let the pranks begin.'

The answering smirks were positively deadly.

Next, all four of them turned to smirk up at Severus at the head table. Severus promptly lost what little colour he had.

Up at the head table, Severus quickly turned to his fellow heads of house. "Pomona, Filius, Minerva, I feel it is my duty to warn you of the very real danger now present in this castle."

The other teachers watched his ghostly white face with rapidly growing alarm.

"Severus, whatever is the matter?"

Minerva exclaimed worriedly. Severus swallowed thickly before continuing.

"You are of course aware of the antics of the Weasley twins?"

His fellow teachers tentatively nodded in assent. A growing suspicion forming in their minds.

"Well I'm afraid to inform you that the other half of their team is now present in the form of the Potter-Black twins. Those two have been playing pranks from the moment they met."

All the teachers in hearing distance paled dramatically at that. Minerva, the groups spokesperson, wet her lips nervously before enquiring,

"What do you mean by that? Surely they can't be that bad."

Severus' bark of laughter was far from reassuring.

"They're worse. The first time I met them, they'd just cast a wandless sleeping charm on Sirius and the first words spoken about them were; 'What is it now? Hovering? Flying? Animate inanimate objects? Coloured rain? Rainbows? Knives? Flooding? The apocalypse?' Rolanda, I feel it my duty to inform you that they've been flying without a broom for as long as I've known them. Not to mention the memorable time they collaborated with the Weasley twins to stick all the furniture to the ceiling and avoid suspicion entirely for weeks. They may all be genius' but they are also the devil incarnate."

The staff table was struck speechless for several minutes before Pomona Sprout finally summed up their feelings with a breathy

"Sweet Circe, how will we survive? How will the school survive?"

Unaware of the fear they were evoking, the group of troublemakers were busy socialising with their housemates. Or each other whenever possible. Harry was having a rather enjoyable conversation with Draco and Teddy Nott when he was suddenly tugged backwards to lean on Fred's shoulder.

"Meet you in the Room of Requirement tonight after curfew. We need to plan our attack carefully if we are to succeed."

Harry nodded gently.

"I'll let Tom know. Are we including Draco and Neville in these plans?"

"Of course. The more hands the smoother this will run."

Harry made a soft sound of agreement at the back of his throat before briefly resting his head against Fred's head and neck before pulling himself back towards the table.

"Sorry about that gentlemen. Ea back there is far too impatient for his own good."

The two boys looked at him in confusion. As a muffled "Oi!" sounded from behind Harry Teddy finally spoke up.

"I'm sorry, but why did you call Weasley that?"

Harry grinned before launching into his explanation.

"Me and Tom grew up in the Hebrides surrounded by Scottish culture and language. When we were young, mum taught us to speak Gaelic and this caused us to give our friends pet names. Fred is Ea, which means fire. George is Kincaid, or warrior. Tom is Raonull or Mighty power and I'm Dour meaning From the water. Neville has one too. He's Artek, our rock. It's strange, for names chosen by small children, they fit scarily well. Fred is fiery and intelligent. George is protective and fierce. Tom is the most magically powerful of us all. I'm smooth and relentless and Neville is the quiet strength that keeps our wild personalities in check."

"Damn right."

Came Fred's muffled voice from directly behind Harry at the Ravenclaw table.

Harry's grin turned mischievous in seconds.

"Of course, they also work as prankster or Marauder names. We use them during prank operations, or at least, versions of them. Fred's always Ea, Kincaid turns to Caid, Raonull to Rao while mine and Nevilles stay the same."

The two Slytherins smirked back and returned to their food. The next time Harry had the chance he leaned in close to Draco to whisper,

"We're meeting the others after curfew, be ready to sneak out."

Draco's eyes widened comically even as he nodded his eager assent. Harry grinned before mentally calling out.

'I presume that familiars are to be present.'

'Of course.'

Chorused back to him. Lips twitching slightly he informed Draco,

"Bring Bahadur with you."

The other boy was only too happy to agree.

Much later, after getting settled in his new home and the house meeting, Harry sat on his bed, waiting for curfew to pass. There had been some minor issues, the older students seemed happy to ignore him and he only received hostility from Pansy Parkinson, Gregory Goyle and Vincent Crabbe. All the other first years were either friendly or politely distant. Harry suspected Severus' influence among the upper years, after all, he knew how much respect his pseudo uncle could invoke.

Finally, curfew was called and all students were in their rooms. Soon enough, Draco was standing beside his bed, Bahadur bumbling around his feet cutely. Harry instantly rose, Andraste already curled gently around his neck.

"Alright, I'll cast as powerful a repelling spell as I can and we'll go meet George outside our common room. I don't know the school yet so he'll have to lead the way."

Harry stood focused for a few seconds until he felt his magic wrapping securely around their forms. Bahadur proved a minor set back as he'd never done this with a separate animal other than a person. Soon enough they were moving off towards the common room entrance and then to the corridor beyond. As soon as they were beyond the entryway Harry sent out his magic until it brushed George's and he grinned, gently tickling the older boys magic until a voice called out.

"Oi! Harry! Knock it off and add me to your ward/spell thingy."

Smirking, Harry swiftly obeyed. As soon as George was safely able to see them, he set upon Harry, arm wrapped around his head, his other hand messing up his hair. Laughing, Harry struggled until he finally escaped to hide behind Draco who watched the whole scene with obvious bemusement. George huffed before throwing an arm around Draco's shoulders and guided him off down the corridor, nose firmly in the air. Still laughing, Harry jogged after them before slinging his arm around Draco's waist while keeping an eye on Draco's Panther.

Soon enough, they were standing in front of a blank stretch of wall. They didn't have to wait long for the other three to join them. Once everyone was there, Fred stalked backwards and forwards in front of the wall three times as a door formed. It was a plain, unassuming door that instantly caused attention to slide away from it. In other words, it was perfect. Glancing around, Fred pulled it open and ushered them all inside.

The room they found themselves in was cosy with a hint of professionalism. A fire crackled in the hearth while a table took up the centre of the room, a whiteboard stood in front of the table while the walls were lined with bookshelves. One wall held a detailed map of Hogwarts that seemed to work exactly like the Marauders Map the twins now held in their possession. Thick carpets covered the stone floor and the room simply screamed comfort and secrecy. Grinning deviously at each other, the group of six sank into chairs around the table, Fred and Harry automatically sitting directly in front of the whiteboard and also the head of the table. Familiars were placed gently in front of the fire as the group settled in for a serious discussion.

Harry spoke first.

"As our newest member I feel like Draco requires a name. All in agreement?"

Five hands solemnly rose into the air as Draco blushed and hunched slightly in his seat.

"Alright then, as chairman of these talks I would like to suggest Gaothaire, meaning free wind. Referring both to his current, birdlike elegance in appearance and our future hope of rescuing him from his parents dominating control."

Draco sat up proudly at this, a contented smile lighting up his features while the others nodded their approval.

"Aire for short."

Declared Neville, grinning across at the smaller boy. Noises of assent were made and the meeting progressed. Fred spoke up next.

"You all know why we're here. A prank attack that has long been anticipated. Now we need to plan."

The mood grew impossibly more focused as Harry rose and picked up a pen, turning to the whiteboard.

"Our target is Dumbledore. He has never been touched in pranking history. We need to change that. Now, ideas."

George spoke up first.

"I say we target those Lemon Drops he's continually snacking on."

The suggestion was eagerly recorded as Fred grinned at his twin.

"Excellent idea Kincaid, any potion we spike them with will be constantly renewed without Dumbledore knowing."

The whole table was now filled with laughter. Draco was the first to speak next.

"You know how much he loves Gryffindor, Why don't we douse them in a potion that not only makes him bald, therefore ridding him of his most defining feature, but also make his features snakelike, possibly green and silver scales."

Tom whooped.

"Gaothaire, that is pure genius! Now, I know there isn't a potion that would suit our needs, so Ea, Dour, you'll have to start experimenting. Think you can do it?"

Fred and Harry exchanged a look, silently communicating in some way before facing the rest of the room.

"Give us-"

"-a week and-"

"-we'll have-"

"-the potion."

The whole group exchanged more smirks, this time of a decidedly vicious quality. Neville spoke next.

"I think that the two twins need to do a school wide prank to announce their presence. No singling people out, nothing malicious, just like our rules state."

The group of four's smirks grew even wider before George purred out.

"Oh don't worry, this one we've had set up for months."

Their resultant laughter was far from reassuring for the other two children.

I know this is short, but I'll write again soon enough. Hope you enjoyed it and thank you to you all for reading this and letting me know what you think. It means a lot to know that people enjoy my work so much.
