The Green Trio

September 15th, 1994

Becoming the school's drug dealers had, by all accounts, been just a happy accident, but the creation of the plant itself had been Cersei's passion project for the first half of their fourth year. As Luka could vividly recall, the girls had spent weekends in the Greenhouse up until Christmas where they grew acquainted with the likes of Neville Longbottom and various herbs until Cersei had finally been able to find the perfect combination. A combination that, unlike regular weed, negated the chances of experiencing a bad trip and threw in a slight amount of hallucinations just for the fun of it.

For a few short weeks after, it'd been entirely for the trio. They'd smoked in the courtyard at lunch, tucked away from the view of nosey professors and rats disguised as students, and gone to class giddy. During Divination, Magic Cap had turned quite useful. On multiple occasions, Trelawny had praised Diana for her ability to read the crystal ball so precisely and nobody was the wiser until rumours made their rounds of what the girls were on. It was only on the first trip to Hogsmeade after winter break anyone actually approached them.

"How much are you selling it for?" said a sixth year Slytherin.

"What?"

"Off it," he'd said. "Everyone knows what you lot have been up to."

Without missing a beat, Luka had answered, "Two galleons for a gram."

Like most things at Hogwarts afterwards, everybody knew—or rather everyone who wouldn't go snitching to the staff knew. There'd been a few veiled attempts to get the girls caught, but they had loyal customers and ears in every social group.

Besides, what teacher would really believe the trio were actually capable of doing what they were doing? Cersei was well liked and on the Hufflepuff Quidditch team, Diana had never set a toe in detention or spoken against a teacher, and Luka gave the appearance of a model student to the point of being made a Prefect.

It was the perfect alibi. 

Sitting on a stone ledge in the courtyard, Luka couldn't help but smirk at the thought as she counted out galleons. They'd made well over a thousand galleons in one semester last year; it'd been two weeks and they'd already made over a hundred.

"Someone's coming," Diana alerted and Luka promptly slid the money into an enchanted coin purse, dropping it in the inside pocket of her robes. The perfect crime.

As the person got closer, Cersei stood, "It's Seamus."

Luka looked up. "Honestly I thought he forgot."

"'Ello there, ladies!" the Gryffindor said, stopping in front of them. "Business going well for ya? I'm fourth year now, ya know?"

Luka sighed, a hint of amusement laced through her breath. "We know, Seamus."

"I can buy from you now, can't I?"

"We were hoping you would." Diana said.

When they'd started selling, the girls had laid out rules for themselves, barring anyone under fourth year from purchasing Magic Cap for obvious reasons (getting eleven year olds high wasn't exactly something they wanted to partake in). The Gryffindor standing in front of them had been one of many third years who'd tried to find a way around it and failed.

Seamus grinned. "Right, how much can 4 galleons get me?"

"Two grams," Cersei said, reaching into her robes and pulling out three baggies. "For you, we'll make it three."

His smile grew, stretching from ear to ear, as he passed her his coins. "Have you ever thought of having a hand in Gryffindor?" he said, nervously glancing at Luka before shifting his attention back to Cersei. "Some of 'em just don't trust the lot of you. Reckon they'd feel better buying in the common room. Less of a chance of being caught, ya know?"
