Chapter Text
Persephone Lily Potter sat on the narrow edge of her bed and watched the sun drag itself over Little Whinging.
The sky was pale gold at the horizon, bruised blue above it. Privet Drive was still half asleep, neat curtains shut, trimmed hedges motionless, every house pretending to be respectable and whole. It made her hate the street even more.
Her hands were clasped too tightly in her lap. Her nails bit crescents into her skin. She barely felt it.
Sirius was dead.
Even now the words refused to settle properly in her mind. They slid against each other like broken glass.
Dead.
Gone.
Lost to the Veil because he had done what Sirius always did—rushed forward, laughing in the face of danger, as if the world had not already taken too much from him.
‘Dammit, Sirius,’ she thought, staring out at the rising sun until her vision blurred. ‘Why couldn’t you stay behind for once? Why couldn’t you choose caution just once?’
Her throat tightened.
Then, because grief in Persephone had always worn anger’s face, the sorrow inside her sharpened.
Nothing held her here anymore.
That thought settled cold and clean in her chest.
For nearly two years, Sirius had been the reason she kept playing the game. The reason she kept smiling when expected. Nodding when expected. Pretending she believed in the shining righteousness of the Light, in Dumbledore’s benevolent grandfather routine, in the fragile little golden girl mask they had all helped build around her.
Sirius had loved her.
Not the symbol. Not the prophecy. Not the weapon.
Her.
And because he had loved her, she had let herself believe she could survive a little longer as the girl everyone wanted her to be.
Now he was gone.
Now there was nothing left worth pretending for.
Her mouth curved, slow and sharp.
‘At least I don’t have to pretend to agree with the Light anymore,’ she thought. ‘And Remus… Remus will come around. Eventually.’
That thought softened the edge of her grief for half a heartbeat before another, much blacker one took its place.
Dumbledore.
The name slid through her mind like a blade drawn across silk.
She wanted—oh, she wanted—to wipe that twinkle right out of his eyes.
He thought himself subtle. Wise. Untouchable. He thought himself such a marvelous actor, such a magnificent manipulator.
He really wasn’t.
Persephone had known for years that something was wrong. Knew it in the little things first: in the way choices around her narrowed whenever they should have opened. In the way truths arrived late, filtered, curated. In the way Dumbledore looked at her as if she were both child and chess piece.
Mostly chess piece.
How the man fooled the masses, she did not know. Then again, most people were idiots. Frighteningly willing idiots, in her experience.
A brutal pounding on her bedroom door tore through the silence.
“Girl, get up and make breakfast! We don’t have all day!”
Petunia.
Persephone did not even flinch.
Something inside her, something tightly wound and long-contained, uncoiled.
‘Well,’ she thought, rising to her feet with eerie calm, ‘if I’m not pretending anymore, I suppose I don’t have to play nice with the Dursleys either.’
That had always been the funny part, really.
They had all believed they were shaping her.
The Dursleys with their fists, their starvation, their contempt.
Dumbledore with his secrets, his nudges, his careful silences.
Even Hogwarts, in its own way, with its expectations and its easy boxes.
None of them had understood what Privet Drive had actually made.
Persephone had learned young that something was wrong with the world she lived in. Learned even younger that nobody was coming to save her. By the time she was five, she had already begun testing the edges of what she could do. Magic had answered her like something waking up and recognizing its own.
The Sorting Hat had been right.
She would have made an excellent Slytherin.
Another bang rattled the door.
“Freak, do you hear me? I said get the hell up!”
A smile touched Persephone’s mouth.
It was not a nice smile.
‘Time to show them who the real freak is,’ she thought.
She opened the door.
Petunia Dursley stood there in her dressing gown, thin mouth pinched, eyes bright with the ugly sort of fury only small-minded people ever managed to perfect.
Persephone smiled brightly.
“Good morning, Aunt Petunia.”
Petunia’s lip curled. “Freak, shut up and go make breakfast.”
Persephone tilted her head, almost thoughtful.
“Mm. No,” she said lightly. “I don’t think so. Today, you’re going to make breakfast for me.”
For one long second, Petunia simply stared.
It was almost funny—watching her try to comprehend defiance from a creature she had spent years treating as less than human.
Then Petunia’s face hardened, and she raised a hand to strike her.
The hand never landed.
Petunia gave a short, choked gasp as invisible force caught her and slammed her backwards into the wall. Her feet left the carpet. Her dressing gown twisted around her legs as magic pinned her there, utterly still.
The temperature in the hall seemed to drop.
Persephone stepped forward.
Her expression never changed. Her voice remained almost cheerful.
“You really don’t understand, do you, Aunt Petunia?” she asked softly. “Those days are over.”
Her eyes glimmered, green gone stranger, deeper, like light caught in poisoned glass.
“I let you do it,” she said. “I let you, your walrus of a husband, and your whale of a son belittle me, beat me, starve me, work me from sunrise to sundown—”
Petunia made a thin, horrified sound.
“—and still,” Persephone continued, voice lilting and terrible, “you wouldn’t have spat on me if I’d been on fire.”
Petunia’s breath came too fast. For the first time in her life, she was looking at her niece as if she had no idea what stood in front of her.
Good.
Persephone smiled wider.
“So no,” she said. “We won’t be doing things your way anymore. We’ll be doing them mine. If you’d like to keep living.”
Petunia swallowed convulsively.
She was frightened. Properly frightened.
And still, because she was Petunia Dursley, because cruelty and stupidity often walked hand in hand, she grasped for the one threat she thought might still matter.
“Y-your freak school will expel you for this,” she said. “You’ll be thrown out!”
Persephone’s face changed instantly.
She widened her eyes. Pressed a hand to her chest. Drew in a dramatic breath.
“Oh, no,” she gasped in mock horror. “Whatever shall I do?”
She held the expression for several beats.
Then she laughed.
Petunia went white.
“That would be true,” Persephone said pleasantly, “if I were using a wand.”
Petunia stared.
Persephone leaned in slightly.
“But I’m not. Wandless magic, Aunt Petunia. Honestly, do try to keep up.”
Petunia’s mouth opened.
Nothing came out.
Persephone’s smile sharpened.
“I had the Trace removed in third year,” she said. “And before you ask—yes, I know exactly what I’m doing.”
That, more than anything, was what frightened Petunia most.
Not the magic.
Not really.
It was the certainty.
The control.
This was not accidental. Not childish. Not wild.
Persephone knew exactly what she was.
Dumblewhore’s first great mistake had been giving her the invisibility cloak in first year.
Once Persephone had possessed it, Hogwarts had opened. Not all at once, but enough. Enough to slip into the library after curfew. Enough to read what she was never meant to read. Enough to realize the world was stitched together with lies and omissions and fear.
Dark magic. Light magic. Grey magic.
People sorted them into boxes because people were simple, and simple made them feel safe.
Persephone had never been simple.
She believed in the equality of all magic.
She also knew what her own core felt like.
Dark.
Petunia’s breath shook.
Persephone’s expression turned sweet.
“So,” she asked, “are we going to have a problem?”
Petunia swallowed again. Then, very slightly, she shook her head.
“N-no.”
“Good.”
With a flick of her fingers, the magic released her.
Petunia stumbled forward, clutching at the wall.
Persephone stepped back, all bright civility again.
“Now,” she said, “we’re going downstairs. You’re going to make breakfast. And while you do, I’ll explain the new rules.”
She turned and walked toward the stairs without waiting to see whether Petunia followed.
Of course she did.
In the kitchen, Persephone sat at the table like she belonged there, like she had always belonged there. Petunia moved stiffly around the room, pulling pans out with trembling hands.
The smell of frying eggs and bacon slowly filled the air.
Persephone rested her elbows on the table and folded her hands.
“After breakfast,” she said, “you’re going to call down your fat husband and your incompetent son. We need to have a family discussion.”
Petunia’s face twitched, but she said nothing.
For once, wisdom had found her.
The silence did not last.
Heavy footsteps thundered overhead. The stairs creaked in protest. A moment later Vernon and Dudley Dursley waddled into the kitchen, pink and broad and offensively alive.
Vernon took one look at the table, at Petunia cooking, at Persephone sitting calmly in a chair as though she had every right to it, and his face turned the color of raw meat.
He jabbed a finger toward her.
“Girl, what the hell do you think you’re doing?”
He advanced.
Petunia spun around. “Vernon, don’t—”
Too late.
Persephone did not even rise from her chair.
Vernon dropped.
He hit the floor with a wheezing scream that never made it past his lips. His whole body seized. His face contorted, veins standing out in his neck as agony tore through him.
Petunia shrieked.
Dudley froze.
Persephone watched, expression unreadable.
After several long seconds, Petunia turned to her with tears in her eyes.
“Please!” she gasped. “Please, Persephone, let him go!”
Persephone went still.
Her name.
Petunia had never used her name.
Not once.
For a moment—just a moment—that landed harder than it should have.
Then she cut the curse.
Vernon collapsed against the linoleum, shaking violently, gasping for breath.
Dudley finally found his voice and started shouting.
Petunia rounded on him so fast he nearly toppled backward.
“Dudley, shut up!”
He gaped at her.
Persephone looked at her cousin with open disgust.
“Dudley,” she said coolly, “it’s a new day. We’re doing things my way from now on.”
She clasped her hands together sharply. The sound cracked through the kitchen like a starting gun.
“Rule one,” she said, “any assault on my person will be met with extreme consequences.”
Vernon was still dragging himself upright, pale and shaking, when she turned to him.
His eyes were wide. For the first time in her life, he looked afraid of her.
Good.
“G-g-girl,” he stammered, “w-wh-what d-d-did you do t-to m-me?”
Persephone’s smile came back.
“That,” she said brightly, “was the Cruciatus Curse.”
Silence fell.
“If held long enough,” she added with a little tilt of her head, “it drives people insane.”
Vernon looked as though he might faint.
“W-what,” he whispered, voice breaking, “i-is the meaning of this?”
Persephone leaned back in her chair.
Her smile deepened.
“Well, Uncle Vernon,” she said, “let me tell you a little story.”
