Melusine
The Serpent’s Shadow and the Lion’s Pride
The morning sun struggled to pierce the thick, enchanted glass of the Great Hall windows, casting a pale, watery light over the four long house tables. For most students, it was a typical Friday after Samhain, but the air in the hall felt fundamentally shifted.
At the Slytherin table, the change was palpable. The three Black sisters—Bellatrix, Andromeda, and Narcissa—were sitting shoulder-to-shoulder for the first time in years. There was no cold distance, no pointed silence; they were leaning in, whispering with a frantic, renewed intimacy that drew stares from across the room. Nearby, Severus Snape and Regulus Black sat so close their robes brushed, their eyes bright with a shared understanding that looked far deeper than mere friendship.
Melusine Asante di Panzilo entered the hall with her usual silent, predator-like gait. She was wearing her cargo pants and the blue tank top, the silver scars on her arms catching the morning light. She didn't look at the sisters. She didn't acknowledge the soul-bonded pair she had liberated the night before. True to her word, she walked straight to the very end of the sixth-year section—the seat of the outcast—and pulled a plate of kippers toward her.
"She’s sitting there again," Narcissa whispered, glancing down the table. "After what she did for us... why does she stay in the shadows?"
"Because she’s smart," Bellatrix replied, her voice lacking its usual erratic edge. "She’s watching. She’s waiting to see if we’re worth the effort she spent on us. Look at the High Table."
Dumbledore was watching Melusine with a gaze so intense it bordered on hostile. Beside him, Professor McGonagall looked troubled, her eyes darting between the strangely unified Black sisters and the girl at the end of the table.
The school day began with History of Magic. Professor Binns dithered on about the Goblin Rebellion of 1612, his voice a droning lullaby. While most students doodled or slept, Melusine sat with a piece of parchment, her quill moving in rapid, jagged strokes. She wasn't taking notes on the lecture; she was drawing complex, geometric diagrams of ley lines and magical intersections. When Binns mentioned a specific blood-ward used by the goblins, Melusine snorted audibly.
"Something to add, Miss Asante?" Binns asked, surprised to be interrupted.
"The ward failed because they used iron rivets in a copper-based ritual, not because of the wizarding reinforcements," Melusine said flatly, not looking up. "Basic alchemy. You can't bind earth-magic with conductive metals without a grounding source."
The Gryffindors in the back, led by Sirius Black, began to snicker. "Listen to the transfer," Sirius called out. "Thinks she’s smarter than a ghost who lived through it."
Melusine didn't even turn around. She simply flicked her fingers, and a tiny spark of blue light hissed through the air, momentarily silencing Sirius’s voice as if his vocal cords had turned to lead. By the time he could speak again, the moment had passed, and Melusine was back to her diagrams.
In Transfiguration, the task was to turn a teapot into a tortoise. While the rest of the class struggled with the precise wand movements McGonagall had demonstrated, Melusine barely moved her hand. She didn't use the standard 'M' shaped flourish. Instead, she tapped the teapot twice, whispering a word that sounded like the crackle of dry leaves.
The teapot didn't just become a tortoise; it became a snapping turtle with a shell made of polished lapis lazuli.
"An... unconventional result, Miss Asante," McGonagall said, peering over her spectacles. "The prompt was a common garden tortoise."
"Common is boring, Professor," Melusine replied. "And the lapis provides better protection against predatory spells. Form follows function."
Across the aisle, a Hufflepuff boy named Arthur was sweating, his teapot merely growing a tail and beginning to whistle. Melusine watched him for a moment. Without a word, she reached over and tapped his shoulder.
"You’re holding the tension in your wrist," she said, her voice surprisingly gentle. "Don't fight the porcelain. Imagine the water inside it turning into blood and bone. Try a circular motion at the end, not a flick."
Arthur blinked, adjusted his grip, and tried again. The teapot vanished, replaced by a perfectly healthy, if somewhat confused, tortoise. He looked at Melusine with wide, grateful eyes. She simply nodded and returned to her own work, ignoring the suspicious glares from the Marauders.
Potions was a double period, and the tension was stifling. Slughorn was beaming, delighted by the "mysterious new talent" in his classroom. They were brewing the Draught of Living Death. While Lily Evans worked with clinical, textbook precision, Melusine was doing something entirely different. She was crushing her sopophorous beans with the side of a silver dagger rather than cutting them, and she added a sprig of dried wisteria that wasn't on the ingredient list.
"Miss Asante!" Slughorn cried, waddling over. "What are you doing? Wisteria is highly volatile in a sedative brew!"
"Only if you don't neutralize the alkaloids first," Melusine said, gesturing to the lavender she had soaked in moonstone oil. "The wisteria allows the drinker to maintain a thread of consciousness while the body sleeps. It prevents the 'death' part of the draught from becoming permanent if the dosage is miscalculated."
Severus Snape, working at the next table, paused. He looked at her cauldron, then at his own. He caught her eye, and Melusine gave him a tiny, imperceptible nod. Severus immediately reached for his own silver dagger and began crushing his beans.
By the end of the lesson, Melusine’s potion was a perfect, clear violet, while Lily’s was the standard silver. Lily looked between the two cauldrons, her face darkening.
"That’s not how the book says to do it," Lily whispered harshly as they cleaned up. "You’re cheating. You’re using shortcuts."
"It’s not a shortcut to understand the soul of the plant, Evans," Melusine replied, packing her vials. "It’s a conversation. Maybe if you stopped shouting at your ingredients, they’d listen to you."
The final class of the day was Care for Magical Creatures, held out on the edge of the Forbidden Forest. The air was crisp, smelling of pine and damp earth. Professor Kettleburn was introducing the class to a herd of Thestrals.
"Most of you won't see 'em!" Kettleburn shouted, gesturing to the seemingly empty clearing. "Only those who have looked death in the eye can perceive the beauty of these beasts."
Melusine walked forward without hesitation. To most of the students, she appeared to be stroking the air, but those who could see—the few who had known tragedy—saw her hand resting on the skeletal, leathery neck of a massive black stallion. The Thestral nuzzled her palm, its white, pupil-less eyes soft.
"They're beautiful, aren't they?" Melusine murmured.
"What are you doing?" Lily Evans demanded, standing a few yards away. She was staring at the empty space, her frustration finally boiling over. "There’s nothing there! Stop pretending there’s something there just to make yourself look special."
Melusine looked at her, her gaze cold and distant. "You can't see them, Evans? How fortunate for you. It means your world is still small and safe."
"They can only be seen by those who have witnessed death," Professor Kettleburn explained gently.
Lily’s face flushed a deep, indignant red. "Well, obviously! It’s because she’s Dark! She’s probably killed people! Did you see her when she arrived? Those scars, those weapons... she’s unnatural. It's a trick, some kind of Dark Magic to make us think she’s some tragic figure."
Lily began to pace, her voice rising in a frantic, uncontrolled fit of rage. "You come here in the middle of the year, you ignore all the rules, you show off in every class, and you act like you're better than everyone else! You’re nothing but a violent, Dark-magic-using freak! How can the Headmaster let someone like you stay here? You don't belong at Hogwarts!"
The class went silent. Even the Marauders looked a bit taken aback by the sheer vitriol in Lily’s voice. Melusine stood perfectly still, her hand still resting on the Thestral. She didn't snap back. She didn't draw a weapon. She just looked at Lily with a hollow, bewildered expression.
"How can you be so mean?" Melusine asked softly. "I haven't said a word to you that wasn't a response to your own bile. Is your world so fragile that the mere existence of someone different makes you want to burn it all down?"
Lily sputtered, unable to find an answer. Kettleburn quickly stepped in, dismissing the class early to avoid a full-blown riot.
As the sun began to set, painting the sky in bruised purples and oranges, most of the students gathered near the Black Lake to enjoy the last of the warmth. Melusine, seeking escape from the overwhelming, chaotic energy of hundreds of teenagers, climbed into the high branches of an ancient oak tree on the outskirts of the lawn.
She sat there, hidden by the golden leaves, trying to breathe. The magic of the school was loud—uncontrolled, emotional, and messy. It grated against her skin like sandpaper.
Suddenly, a commotion broke out below. Two small figures were sprinting across the grass, their green-trimmed robes fluttering. They were first-year twins, a boy and a girl, their faces pale with terror.
"Get back here, you slimy little snakes!"
James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew were in hot pursuit, their wands out. James was laughing, throwing minor stinging hexes at the children’s heels.
"Let’s see if snakes can swim!" Sirius shouted, a mean glint in his eyes.
The twins ran past a group of Gryffindor prefects and older students, including Lily Evans. None of them moved. Lily actually laughed, pointing at the boy as he tripped and scrambled back up.
"They’re just giving them a scare, Mary," Lily said to her friend, her voice carrying in the evening air. "It’ll teach them not to be so arrogant."
Melusine didn't think. She didn't plan. She simply dropped.
She fell from the branch like a stone, landing silently on the grass directly between the terrified twins and the Marauders. She caught the girl by the shoulder, pulling both children behind her back.
James and Sirius skidded to a halt, their eyes widening.
"Move aside, Panzilo," James snapped, his wand leveled at her chest. "We’re just having a bit of fun. Traditional house rivalry, you know?"
"I don't care about your houses," Melusine said, her voice a low, dangerous growl. One of her tattoos—a dragon entwined with thorns—began to glow with a faint, pulsing blue light. "I will not stand by and see children cry. Not again. Not ever."
"They're just Slytherins," Sirius spat. "They’re born evil. We’re just getting a head start on them."
"They are children!" Melusine roared, the sheer force of her magic causing the grass at her feet to frost over. "And you are cowards! Four against two? Older students against first-years? Is this the 'Light' Dumbledore brags about?"
James took a step back, his bravado wavering as he saw the raw power rolling off her. But he couldn't back down—not with the whole school watching.
"I challenge you to a wizarding duel!" James shouted, his voice cracking. "Right here. Right now. Unless you're too 'Dark' to fight fair."
Melusine looked at him with utter contempt. "Yeah. Sure. Whatever keeps your ego from bruising, Potter."
She turned around, dropping to one knee in front of the shaking twins. "Go," she whispered, gesturing toward the lake where a tall Slytherin prefect was watching. "Go to your prefect. Tell him everything. You're safe now."
The twins nodded fearfully and bolted toward the group of Slytherins. Melusine stood back up, turning to face James.
Remus Lupin stepped forward, looking uncomfortable. "As a prefect, I'll... I'll officiate. First to disarm or incapacitate wins. No Unforgivables."
"Begin!" Remus shouted.
James didn't wait. "Expelliarmus!"
Melusine didn't even draw her wand. She stepped to the left, the red light of the spell whistling past her ear. She moved with a fluid, terrifying speed, dodging a second and third hex with the grace of a dancer.
She reached into her belt and drew a wand—not the one Dumbledore had given her, but a dark, gnarled thing made of elder and serpent bone.
"Sectumsempra!" she barked.
The spell didn't just slash; it hit James like a physical weight, blasting him off his feet and sending him tumbling across the grass. His wand flew from his hand, spinning through the air. Melusine caught it effortlessly.
The lawn went dead silent.
"I win," Melusine said. She walked over to the groaning James, dropped his wand onto his chest, and turned her back on him without a second glance.
The Marauders scrambled to help James, shouting about the infirmary and how "this isn't over," but Melusine was already walking away.
By the lake, the Slytherin prefect, Lucian, was tending to the twins. He turned to Severus Snape, who was standing with the Black sisters.
"Severus," Lucian said, his voice hushed. "That spell she used... wasn't that the one you were working on in the common room last month?"
Severus felt a chill go down his spine. "Yes. But only you, the other prefects, and my friends know about it. I haven't even written it down in my main journal yet."
"Then how did she know it?" Andromeda asked, her eyes fixed on Melusine’s retreating back.
"She said she learned from the best," Regulus whispered, a strange smile touching his lips.
That evening, the Slytherin common room was quieter than usual. When the students entered, they found Melusine in her usual chair by the fire. She had changed into a high-necked, sleeveless crop top of deep blue, her tattoos and scars gleaming in the firelight. A long, rustic maxi skirt flowed around her legs, and she wore an oversized sage-green cardigan draped over her shoulders.
She looked peaceful, her eyes buried in a book, a large blue stone on her necklace catching the light.
Severus walked up to her, the rest of the house lingering behind him. "The spell, Melusine," he said quietly. "Sectumsempra. How?"
Melusine looked up. Her eyes were weary, but there was a flicker of something like warmth in them as she looked at him and Regulus.
"I told you. I learned from the best," she said. "In another time, in another place, you were the only one who had the courage to create something that could actually stop a monster. I just remembered the lesson."
She refused to elaborate further, turning her gaze back to her book.
One of the first-year twins, the little girl, walked up to Melusine’s chair. She didn't say anything; she just reached out and tentatively touched the edge of Melusine’s cardigan.
Melusine looked down. "I've seen children cry," she said, her voice loud enough for the entire common room to hear. "I've seen them broken by people who thought they were heroes. I will not stand by and see it happen twice. Not while I have breath in my body."
The little girl smiled and sat down on the rug at Melusine’s feet. One by one, the other Slytherins began to move. They didn't crowd her, and they didn't ask more questions, but the atmosphere had changed. The invisible wall at the end of the table was gone.
Bellatrix sat in the chair opposite her, Narcissa and Andromeda taking the sofa nearby. They didn't need to say it. The House of Snakes had found its protector, and for the first time in a long, long time, they felt like they were home.
