Hogwarts, for all its ancient magic and storied history, had quietly abandoned the idea of being a serious institution somewhere around the third goblin rebellion.
No one had written that down, of course. There were no official decrees, no policy changes, no sternly worded letters. It was more… cultural. A slow drift into chaos that everyone acknowledged but no one questioned—because, frankly, it worked.
Heather Potter certainly wasn't going to question it.
She lounged at the Gryffindor table, feet propped up on a chair she wasn't technically using, idly stirring her tea with the end of her wand. The tea had long since gone cold, but that didn't matter. It was the principle of the thing.
Across the hall, Daphne Greengrass sat like a statue carved from frost and mild disdain, her posture perfect, her expression unreadable. She hadn't moved in at least five minutes.
Heather squinted at her.
"Do you think she blinks?" she asked.
Ron, halfway through eating something that vaguely resembled eggs, paused. "Who?"
Heather pointed lazily. "Ice Queen of Slytherin."
Ron followed her gaze, then shrugged. "Probably. Would be weird if she didn't."
"Mm. I'm not convinced."
As if summoned by doubt alone, Daphne blinked.
Heather gasped softly. "There it is. Rare sighting."
Daphne's eyes flicked over—sharp, precise, and unmistakably aware she was being observed. For a moment, there was a silent exchange: cool judgment meeting carefree curiosity.
Then Daphne turned away, dismissing her entirely.
Heather grinned. "I like her."
"Why?" Ron asked.
"She looks like she'd stab someone for breathing wrong. That's commitment."
At the staff table, things were… less composed.
Professor Sprout was in the middle of an intense negotiation with Professor Flitwick, their voices low but urgent.
"I'm telling you," Sprout muttered, pushing a small parchment across the table, "supply's been inconsistent since the third years started experimenting."
Flitwick adjusted his glasses, frowning at the parchment like it contained the secrets of the universe. "You can't expect quality control if you outsource to amateurs."
"They're not amateurs," Sprout snapped. "They're students. There's a difference."
"That's worse."
Nearby, Professor McGonagall was nursing what was very obviously not tea.
"Is that… whiskey?" Hermione whispered, scandalized.
Heather didn't even look. "Breakfast of champions."
At the center of it all sat Dumbledore, humming cheerfully to himself while attempting to stack toast into a structurally unsound tower.
"Balance," he murmured, placing another piece on top. "Life is all about balance."
The tower collapsed.
Dumbledore clapped once, delighted. "Ah! A lesson."
"No one knows what lesson that is," McGonagall said flatly.
"Neither do I," Dumbledore agreed. "But it felt important."
Defense Against the Dark Arts was… technically still a class.
Today's professor—a wizard whose name Heather had forgotten within seconds of hearing it—was attempting to explain the dangers of dark creatures.
"…and so, you must always remain vigilant," he concluded, pacing nervously. "Darkness can take many forms."
A hand shot up.
He hesitated. "Yes… Miss Potter?"
Heather leaned back in her chair. "Hypothetically, if the darkness is more organized than the school, do we report it or take notes?"
There was a pause.
"…I beg your pardon?"
"Well," she said, gesturing vaguely, "I've seen more structure in the black market greenhouse operations than in our timetable. Just wondering which one we're meant to learn from."
A few students snorted.
The professor looked like he might faint.
"Miss Potter, that is highly inappropriate—"
"Is it wrong, though?" she asked, genuinely curious.
He opened his mouth.
Closed it.
"…No," he admitted weakly.
"Thought so."
Later, in the greenhouses, the air was thick with the scent of damp earth and something far more questionable.
Heather crouched beside a row of suspiciously vibrant plants, watching as a Hufflepuff carefully tended to them like they were delicate works of art.
"Those aren't for class, are they?" she asked.
The student glanced around before leaning in. "Extra credit."
"Right."
At the far end, Professor Sprout stood like a general surveying her troops.
"Careful with that batch!" she called. "Last time we had a mix-up, Professor Slughorn tried to grade a teapot."
Heather nodded slowly. "Efficient system."
"Very," the Hufflepuff said proudly.
That evening, as the castle settled into its usual hum of barely-contained disorder, Heather found herself once again watching Daphne.
The Slytherin sat alone, reading, untouched by the chaos around her.
Calm. Controlled. Untouchable.
Heather tilted her head.
"Hey," she said, sliding into the seat across from her without invitation.
Daphne didn't look up. "You're in my space."
"Technically, it's a chair."
A pause.
Then, slowly, Daphne closed her book and met her gaze.
There was something sharp there. Assessing.
"You're either very brave," Daphne said, "or very stupid."
Heather grinned. "Why not both?"
Another pause.
Then—just barely—Daphne's lips twitched.
"…Perhaps."
Heather leaned back, satisfied.
Yeah.
She definitely liked her.
This is a preview, don't take it as requirement. I had Harry genderswapped because people like Heathers personality more in women than men, it feels more natural. If I'm wrong about that, tell me and I'll do my best to not make that mistake again.
Now, this is idea will have two chapters to it, there will be the preview(this) chapter, and a staff rulebook, so if you want to use this idea, I recommend reading the next chapter with it.
Last note, just because I genderswapped Harry, doesn't mean you need to do the same, just use a different character, or make an oc for your story if you wish. A preview chapter only gives you an idea of what the story is supposed to be about, it doesn't need to be used in the story itself.
