Yeah, so things are definitely different in this AU. Lucians is our OC and who we'll be following for most of this story, and he's extremely powerful. But don't worry, he's not at the pinnacle of power in this world; he's got others to look out for.
...
The Great Hall blazed with the light of thousands of floating candles. Their warm glow reflected off the enchanted ceiling, which tonight showed a clear, star-dusted sky, and off the long house tables already crowded with students. The air smelled of polished wood, old stone, and the promise of food that had not yet appeared. At the Gryffindor table the familiar cluster had gathered: the Weasley siblings, Neville Longbottom, Seamus Finnigan, Dean Thomas, Hermione, Ron, and Harriet herself. Conversation rose and fell in comfortable waves as everyone compared summers, complained about homework that had already been assigned, and speculated about the new Defence professor whose books had taken over half the shop windows in Diagon Alley.
Ginny was missing, of course. She would be among the first-years still waiting outside. Harriet found herself glancing toward the great oak doors more than once, remembering with sudden clarity how it had felt to stand on the other side of them only a year ago, heart hammering, the Sorting Hat's song still echoing in her ears.
Ron was in the middle of an exaggerated story about a garden gnome that had bitten Fred's ankle when the doors finally swung open. Professor McGonagall entered first, her tartan robes crisp, expression as stern as ever. Behind her came the line of first-years, small and wide-eyed, still damp from the boats. Ginny walked near the middle of the group, freckles standing out against pale skin, her gaze sweeping the Hall with open wonder. Harriet felt a small, unexpected pang of protectiveness.
The first-years were led to the front. The Sorting Hat, patched and battered, sat on its stool and immediately launched into its annual song. Harriet listened with only half her attention. Her eyes had drifted past the nervous eleven-year-olds to the open doorway at the far end of the Hall.
Lucian stood there.
He had changed out of the Muggle clothes. The plain black school robes suited him strangely well, though they bore no house crest yet. His long dark hair was tied loosely at the nape of his neck, and the jagged black scar across his face caught the candlelight like a crack in porcelain. He remained just inside the doors, posture relaxed, hands in his pockets, watching the ceremony as though it had nothing to do with him.
Whispers began almost at once along the Gryffindor table.
"Who's that?" Neville asked, squinting.
Hermione glanced over, then frowned. "That's Lucian. The boy from the train. I told him you were a friend of ours. Didn't he find you?"
Neville shook his head. Seamus and Dean both claimed they had never seen him. Percy, sitting further up the table with the other prefects, leaned over with the air of someone who possessed important information.
"He's the transfer from Diagon alley," Percy said in a low voice. "They often keep transfer Sortings separate so the student isn't overwhelmed by the first-year ceremony. Perfectly standard procedure."
The Sorting continued. Names were called, the Hat shouted house after house, and the first-years scattered to their new tables to applause. Ginny was Sorted into Gryffindor amid loud cheers from the Weasleys. Harriet clapped hard enough to sting her palms, smiling when Ginny slid into the seat across from her looking both terrified and delighted.
When the last first-year had been placed, Professor McGonagall the Hat, but instead of carrying it away she simply set it back down and returned to her seat. A few students noticed the oddity and murmured. Harriet felt the same low unease she had felt on the train when Lucian spoke of promises.
Albus Dumbledore rose.
The Hall quieted at once. The Headmaster looked as he always did at the start of term: half-moon spectacles gleaming, long silver beard neatly combed, eyes twinkling behind a calm smile. He spread his arms in welcome.
"Good evening, and welcome—welcome once again to another year at Hogwarts. To our returning students, it is a pleasure to see you. To our first-years, congratulations on the journey and the Sorting. Before we begin the feast, and before I trouble you with the usual announcements regarding the Forbidden Forest and Mr Filch's ever-growing list of banned items, there is a small matter of unusual business."
He stepped out from behind the staff table and began a slow circuit toward the Sorting Hat, speaking as he walked.
"Transfers to Hogwarts are rare. Exceedingly rare. In my time as Headmaster I have overseen only a handful. This year, however, we are fortunate enough to receive one. Because the circumstances are… particular, I elected to keep the student's name from the ordinary lists. I hope you will forgive an old man's indulgence. I have not had the pleasure of using the Sorting Hat myself for a number of years, and I find I rather missed it."
A low ripple of curiosity moved through the Hall. Harriet glanced at the staff table. Professor McGonagall was speaking rapidly behind her hand to Flitwick. Madam Hooch looked openly puzzled. Snape's face was a careful mask, but his eyes were fixed on Dumbledore with unusual intensity.
Dumbledore patted his robes, frowning slightly.
"I had the parchment right here a moment ago…" He searched an inner pocket, then another, then produced a small folded square of cream-coloured paper with a flourish that suggested the delay had been deliberate. He unfolded it, adjusted his spectacles, and looked out over the silent Hall.
"Please welcome," he said, and every syllable landed with quiet precision, "His Majesty, Lucian Draven von Soren el'Theron Sanguin Bloodthorne."
The name rolled out slowly, each syllable given its full weight.
The name rolled through the Hall like distant thunder.
For a long moment nothing happened.
Then the candles flickered, not as though a wind had touched them, but as though the light itself had hesitated. The air grew heavier, thicker, charged with something old. Harriet felt it press against her skin the way the air pressed before a storm.
At the Slytherin table the change began slowly. A seventh-year prefect near the far end went very still. Then another. One by one, older students in green and silver began to rise, not in a sudden rush, but in a staggered, reluctant wave, as though each of them was fighting the instinct and losing. They stood and bowed from the waist, faces pale, eyes fixed on the floor.
The ghosts followed.
Nearly Headless Nick's head lolled further forward as he inclined the ragged stump of his neck. The Bloody Baron swept into a deep, formal bow that sent his chains clanking softly. The Fat Friar clasped his hands and bent. The Grey Lady drifted lower until her feet almost touched the floor. Even Peeves, hovering near the rafters with a mouthful of chalk he had been about to drop, froze, eyes wide, and performed something that might once have been a courtly bow if Peeves had ever known what courtly meant.
Harriet's heart was beating too hard. She watched Lucian begin the long walk from the doors toward Dumbledore. He did not hurry. He did not look at the students who were standing. He moved the way someone moved when they had been raised to understand that rooms would part for them.
Percy Weasley stood so quickly his chair scraped. He grabbed Fred's sleeve, then George's, hissing urgently. The twins rose, looking bewildered. Ron remained seated, mouth open, until Percy's furious whisper reached him.
"Get up, Ronald, or Father will send a Howler that will make Mum's look like a love note."
Ron stood. Harriet found herself on her feet without deciding to stand. Something in the air simply required it. Hermione rose beside her, one hand gripping the edge of the table.
Further down the Gryffindor table Oliver Wood was staring at Lucian with an expression Harriet had never seen on him before. Hermione leaned across.
Hermione's voice was barely audible. "I've never even heard of them."
"Oliver… who are the Bloodthornes?"
Oliver's voice came out rough, almost hoarse.
"If Dumbledore isn't playing some kind of joke… that boy is one of them. They're not just another pureblood family. They're the royal line. The ones who rule Britain and America both, magical and Muggle, from the shadows. Most people think they're a myth. They're not. And they haven't set foot in this castle in centuries."
Hermione's face went pale. Percy, still standing rigidly, added in a near-whisper, "Claiming the name falsely is said to carry a curse that follows your blood for generations. If he is truly a Bloodthorne…"
He did not finish the sentence.
Lucian reached the stool. Dumbledore's smile was warm, but there was something older and more careful beneath it.
"Welcome to Hogwarts, Your Majesty."
He gestured for the Hall to be seated. The sound of hundreds of students sitting down again was loud in the charged quiet. Lucian sat. Dumbledore lifted the Sorting Hat and settled it onto the boy's head with both hands.
The Hat's mouth tore open at once.
"Well," it said, and the voice carried to every corner. "A Bloodthorne. It has been a very long time. Not since the days when Merlin himself sat where you sit now, if these old seams can still be trusted."
Lucian's mouth curved, the first real expression he had shown since entering the Hall.
"It's good to be remembered."
The Hat fell silent while it worked. The silence stretched. Students leaned forward. At the Slytherin table Draca Malfoy sat rigid, hands clenched in her lap. Vivienne watched from further down the bench, eyes narrowed, calculating.
At last the Hat spoke again, almost conversationally.
"Courage enough to walk into danger without flinching. A mind carrying more knowledge than is comfortable at your age. Friendship with creatures most wizards would run from. And underneath it all… a quiet, relentless drive to prove yourself on your own terms. Ambition. Cunning. A natural understanding of power. I know exactly where you belong."
The Hat's voice rose to its familiar roar.
"SLYTHERIN!"
The Slytherin table erupted. Applause, cheers, and more than a few looks of pure calculation swept the green-and-silver ranks. The rest of the Hall reacted more unevenly: confusion from the younger students, unease from those who understood the name, and from the oldest purebloods a kind of wary, assessing silence. Lucian removed the Hat himself, returned it to Dumbledore with a small nod, and walked the short distance to the Slytherin table. He took the empty place beside Draca Malfoy as though it had been waiting for him.
Draca turned her head just enough to look at him. Her voice was low and tight.
"What the hell was that?"
Lucian reached for a goblet, entirely unhurried. "A Sorting. I believe that's what they call it here."
"You know what I mean." Her eyes flicked to the older students still watching him with something close to reverence. "The bows. The name. You're a Bloodthorne."
He took a sip of pumpkin juice, then set the goblet down with care. "I did mention I was a transfer under special circumstances."
"You sat with us on the train," Draca said, the words edged with something that might have been betrayal. "You talked about Quidditch. You never said a word."
Lucian's mouth curved, small and private. "You never asked."
Vivienne leaned in from Draca's other side, voice silky and dangerous. "Father is going to lose his mind when he hears about this."
"I imagine he will," Lucian agreed mildly. "He seemed dramatic when we met."
Marcus Flint, sitting further down, let out a low, incredulous laugh. "A Bloodthorne. In Slytherin. This year is going to be interesting."
Dumbledore had returned to the staff table. He raised his arms once more, still smiling that careful smile.
"Thank you for that most interesting Sorting. Now, the usual notices. The Forbidden Forest remains, as ever, forbidden. Mr Filch has asked me to remind you that the list of objects forbidden inside the castle has been extended this year; the complete list is posted on the door of his office. And finally, I am delighted to introduce our new Defence Against the Dark Arts teacher, Professor Gilderoy Lockhart."
Lockhart stood, beaming, and offered a little wave. The applause he received was scattered and distracted at best. Most of the Hall was still watching the dark-haired boy now seated among the Slytherins. Lockhart's smile flickered, then returned at full wattage, though it no longer reached his eyes.
Dumbledore smiled at the relatively weak welcome and turned back to the students. "Thank you, Professor Lockhart; now let the feast begin."
Dumbledore clapped his hands once.
Food appeared. Roast meats, Yorkshire puddings, vegetables, gravies, pies, everything the house-elves could invent in a single breathless moment. The feast had begun, but the usual roar of conversation was replaced by intense, low-voiced discussions at every table.
At the Gryffindor table Ron finally found his voice.
"He's a what?"
No one answered him immediately. Harriet kept her eyes on the Slytherin table. Lucian was unfolding a napkin with calm precision while the students around him openly measured him. He did not look triumphant. He did not look overwhelmed. He looked, if anything, mildly inconvenienced by the entire production, as though the dramatic reveal had been a piece of theatre he would have preferred to skip.
She remembered the boy in Muggle clothes on the train, the easy way he had teased her about scars, the brief shadow that had crossed his face when he spoke of a promise. None of that had prepared her for the way the castle itself seemed to recognise him, or for the sight of ghosts bowing one by one, or for the slow, heavy authority that had filled the Hall when Dumbledore spoke his full name.
Hermione was already speaking in a low, urgent voice to anyone who would listen. "The Bloodthornes. I've never seen the name in any of the standard histories. Not once. If they're real, if they actually rule both magical and Muggle Britain and America from the shadows, then everything we think we know about the Statute of Secrecy is… incomplete."
Oliver Wood rubbed a hand over his face. "My dad used to tell stories. Said his grandfather once saw a Bloodthorne during an old war. Said the man walked through a battlefield like it was a garden path and the Dark wizards just… got out of the way. I always thought he was making it up."
Fred leaned in, unusually serious. "Did you see Peeves bow? Peeves. I didn't know he could do that without exploding."
George nodded. "Nick looked like he was about to cry. Or as close as a ghost can get."
At the Slytherin table the conversation was sharper, more calculating. Older students spoke in low, rapid voices about bloodlines and old debts and what it meant that a Bloodthorne had chosen their house. Draca sat rigid beside Lucian, still processing. Vivienne watched him with the cool interest of someone already revising every plan she had made for the year. Lucian himself ate with quiet efficiency, answering the occasional question with the same calm vagueness he had shown on the train, offering nothing he did not wish to give.
Harriet reached for her goblet. Her hand was not entirely steady.
Around her the feast continued. The taste of the food barely registered. The year had only just begun, and already the ground beneath her feet felt less solid than it had an hour ago. She kept glancing across the Hall, unable to stop herself. Every time she did, she found Lucian already looking elsewhere, as though the weight of an entire school's attention was nothing more than mild weather.
The candles burned on. The enchanted sky wheeled slowly through its stars. And Hogwarts, for the first time in centuries, had a Bloodthorne in residence.
