Rain lashed against the windows of the small cottage in Godric's Hollow.
Inside, the nursery was filled with the soft, warm glow of a crackling fireplace, though the air felt heavy with unspoken dread.
Wails rose from the two cribs placed side-by-side near the window.
Harry cried with a fierce, demanding strength, his tiny fists flailing against his blankets.
Lia's cries were quieter, a breathless, rhythmic weeping that seemed to echo the tension in the room.
Sybill Trelawney's voice still haunted the minds of the Order.
A son marked by sacrifice.
James Potter stood by the window, his knuckles white as he gripped his wand.
Lily stood over the cribs, her fingers brushing Harry's dark tuft of hair before moving to Lia's softer, downy brow.
Wards flared red.
Gold sparks suddenly rained down outside as the perimeter defenses shattered into brilliant, fading embers.
Remus Lupin burst through the fireplace in a rush of green flames, his face pale and splattered with soot.
"He's here," Remus breathed, coughing as he stepped onto the rug.
James didn't hesitate.
He grabbed infant Lia from her crib, wrapping her tightly in a warm woolen blanket, and shoved her into Remus's arms.
"Take her," James ordered, his voice cracking with desperation. "Our prophecy only speaks of a son. Save Lia. Go!"
Remus looked at the baby girl, then at James.
A terrible, silent understanding passed between them.
Without a single word, Remus spun on his heel and disappeared with a sharp, echoing crack of Apparition.
Upstairs, Lily slammed the nursery door, dragging a heavy oak wardrobe across the frame with a desperate flick of her wand.
Downstairs, the front door exploded inward with a deafening blast.
Heavy, deliberate footsteps echoed on the stairs, slow and terrifying.
James stood at the bottom of the landing, his wand raised high.
"Lily, take Harry and run!" he yelled.
Green light flared, illuminating the hallway in a sickly, emerald glow.
James fell, his eyes staring blankly at the ceiling.
Cold air rushed into the nursery as the door splintered into kindling.
Lord Voldemort stepped over the wreckage, his crimson eyes locking onto the crying boy in the crib.
"Not Harry, please," Lily begged, throwing her arms wide to block the crib. "Take me instead!"
"Step aside, girl," the high, cold voice commanded.
She refused.
Green light erupted again, casting long, twisted shadows against the walls.
Lily collapsed like a broken doll.
When the Dark Lord turned his wand toward the infant, he expected an easy victory.
He did not expect the ancient magic of a mother's sacrifice to manifest.
A blinding barrier of pure gold light erupted from the child.
Rebounding magic tore through the room, shattering the ceiling and blowing the roof into the night.
Voldemort's body disintegrated, his soul ripped apart and scattered into nothingness.
Silence descended upon the ruined cottage.
---
Ash drifted through the night air like black snow.
Remus returned to Godric's Hollow hours later, his legs shaking as he walked up the gravel path.
Lia was asleep in his arms, tucked beneath his heavy traveling cloak.
He climbed the shattered staircase, his eyes burning as he looked at the wreckage.
Harry was crying in his crib, a jagged, bleeding cut shaped like lightning on his forehead.
Sirius Black burst into the room moments later, his face pale and his eyes wild with grief.
"They're gone, Remus," Sirius choked out, dropping to his knees beside Lily's body. "They're gone."
Remus knelt beside him, placing a gentle hand on his friend's shoulder.
"We have the kids," Remus whispered. "We have to protect them now."
Looking at the twins, the two men made a silent vow.
Neither child would ever grow up alone.
Justice came swiftly in the quiet weeks that followed.
Without the chaos of an ongoing war, the Ministry conducted a thorough investigation.
Peter Pettigrew's betrayal was brought to light before he could escape the country.
Sirius was fully exonerated, his name cleared of all treason.
Together, the two men built a quiet life in a cottage far from the prying eyes of the wizarding world.
Years blurred into a beautiful, chaotic routine.
Harry grew up adventurous and reckless, constantly scraping his knees and dragging his sister into trouble.
Lia was different.
She watched people with an intensity that made adults uneasy.
She wanted to know why Sirius smiled when he looked at old photographs, or why Remus's voice softened when he spoke of the past.
"Why do they do that?" she would ask, her grey eyes bright with curiosity.
Remus taught her to read before she was five, filling her room with history books and magical theories.
Sirius taught her to fly, laughing as she performed perfect, calculated banks instead of Harry's wild dives.
Harry never saw her as anything other than his twin sister.
Lia never saw Harry as a legend.
They were just family, bound by the ashes of a night they barely remembered.
---
On their eleventh birthday, two owls arrived during dinner.
Harry snatched his letter first, tearing the envelope open with messy enthusiasm.
"Hogwarts!" he shouted, waving the parchment. "I'm going!"
Lia looked at her plate.
Two letters sat beside her cup.
One was written in the familiar green ink of Hogwarts.
A silver seal adorned the second envelope, heavy and cold to the touch.
"What's that one?" Harry asked, his mouth full of potatoes.
Remus sat down beside her, his expression warm.
"I sent some of your essays to them, Lia," Remus explained gently. "They only accept twelve students a year from across the globe."
"Asterion is different," Sirius added, leaning over the table. "They teach magic, law, and diplomacy. But it's in Switzerland."
"If I go there..." Lia paused, looking at her brother's excited face. "Who will I be?"
Remus smiled gently.
"Whoever you decide to be."
Harry grabbed her hand. "I'll miss you. But you're too smart for Hogwarts anyway."
Sirius grinned, ruffling her hair. "Go make Britain jealous, kiddo."
She made her choice that night.
Lia wanted to see who she was outside of her brother's shadow.
In Britain, she would always be the twin of the Boy Who Lived.
In Switzerland, she could be herself.
---
Snow-capped peaks surrounded the towering spires of Asterion Academy.
Lia adjusted her silver-trimmed robes as she walked through the high-arched corridors.
Switzerland was cold, but the education was fiery.
Asterion did not divide its students by house or personality traits.
Instead, they were judged solely on their merit, their intellect, and their adaptability.
Lia thrived in this environment.
She spent her mornings mastering advanced transfiguration and her afternoons debating political philosophy with international scholars.
"Magic is not just a tool for combat," she argued during a public forum in her fourth year. "It is the architecture of influence."
Her professors watched her with quiet awe.
She was not just brilliant; she was hyper-observant.
While other students memorized wand movements, Lia memorized the micro-expressions of her peers.
She learned how a twitch of the jaw signaled a bluff, and how a slight shift in posture revealed insecurity.
House-elves in the kitchens knew her by name, always delighted when she stopped to ask about their families.
Difficult research projects never intimidated her; she volunteered for the hardest assignments to master problem-solving.
By her fifth year, she had won three international academic debates and published a paper on the reformation of magical law.
Her reputation began to bleed across the borders.
Back in Britain, the wizarding world was unprepared.
"Have you heard?" a Gryffindor student whispered in the common room. "That Asterion prodigy is transferring."
"I heard she's a Potter," a Ravenclaw added, looking up from her book.
Hogwarts erupted into chaotic speculation.
Gryffindor assumed she would join her brother.
A Potter belonged in red and gold, simple as that.
Ravenclaws argued she belonged with them.
A girl who debated academy professors and rewrote spell theories couldn't possibly go anywhere else.
Hufflepuffs spoke of her kindness.
Stories had traveled of her helping younger students and thanking the academy house-elves by name.
Slytherins remained quiet.
They didn't care for rumors of kindness, and they certainly didn't expect a Potter to have real ambition.
They barely looked up when the topic arose.
---
Graduation from Asterion was a grand, solemn affair.
Lia stood at the podium as the valedictorian, her silver medal gleaming against her chest.
Invitations arrived from every major magical institution in the world.
Durmstrang offered her a specialized track in dark defense.
Beauxbatons promised her a seat in their diplomatic corps.
Even Ilvermorny sent a golden owl, offering her a full research fellowship.
Lia turned them all down.
She chose Hogwarts.
Albus Dumbledore had written to her personally, but her decision wasn't out of loyalty to him.
Hogwarts was the heart of Britain.
Its four Houses were not just dormitories; they were four distinct philosophies of power.
To lead, one had to understand how people chose to follow.
She needed to understand Britain from the inside.
---
September first arrived with a torrential downpour.
Inside the Great Hall, thousands of candles floated beneath an enchanted ceiling mimicking the stormy sky.
Harry sat at the Gryffindor table, tapping his fork anxiously.
Beside him, Hermione Granger adjusted her robes.
"Do you think she'll be sorted into Gryffindor?" Hermione asked.
"Of course she will," Harry said, though his voice held a trace of nervousness.
At the staff table, Albus Dumbledore watched the entrance doors with a quiet smile.
Professor McGonagall stepped up to the podium, a long scroll of parchment in her hands.
Silence fell over the Great Hall.
Every eye fixed on the heavy oak doors at the back.
McGonagall cleared her throat, her voice echoing off the stone walls.
"Lia Potter."
Heavy oak doors swung open.
