King's Cross Station had seen many things in its hundred and fifty years of existence.
It had seen wars begin and end. It had seen royalty pass through its doors so many times the stonework had practically stopped noticing. It had seen, on one memorable occasion in 1973, a man attempt to smuggle a live ostrich through the main concourse in a hat, and had survived that too.
It had never seen anything quite like the Flamel-Pendragons on a school run.
They arrived the way they did most things — without announcement and with the particular quality of presence that made the crowd part around them without quite knowing why. Nicolas had his hat on at an angle that suggested the morning had involved an argument with a mirror. Perenelle had a list. Edouard had somehow acquired coffee from somewhere despite the fact that they had been in a car for the past forty minutes. Caedmon was telling a story to nobody in particular about a train journey he'd taken in 1887 that had involved a runaway horse and a very confused station master, and seemed to find it funnier each time he told it.
In the middle of all of it walked Cael, Albion across his shoulders and Astrape on his arm and a bag of chocolate that he was working through with the focused dedication of someone who had been told by his grandmother that chocolate was supplementary and had decided to address this diplomatically before she could enforce it.
He was going to Hogwarts.
He had known this since the letter arrived. He had thought about it through the grimoire ceremony and the visit to Newt and approximately six hundred chocolate frogs' worth of the intervening weeks. He had been perfectly calm about it.
He was still perfectly calm about it.
He was almost entirely certain he was calm about it.
"You've got everything?" his mother said, appearing at his elbow.
"Yes."
"Grimoire."
He touched it at his belt. "Yes."
"Astrape's feed."
"Yes."
"The—"
"Mum." He looked at her. "I have everything."
Seraphine looked back at him. She was doing the thing she sometimes did where she looked at him and forgot, for just a moment, to look like herself — the expression that lived underneath the composed fierce competence of her, the one she didn't give to anyone else. It lasted approximately one second before she straightened and became herself again.
"Right," she said. "Good."
She reached out and fixed his collar. It didn't need fixing. She fixed it anyway.
Platform Nine and Three Quarters was everything the muggle side of King's Cross was not — loud and warm and smelling of steam and magic and the particular excitement of several hundred children going somewhere wonderful. The Hogwarts Express stood gleaming and red at the platform's edge, enormous and cheerfully certain of itself, already breathing great clouds of white steam into the September air.
Cael stepped through the barrier and stopped.
He had read about the Express. He had heard about it from Dumbledore, who had mentioned it with the particular fondness of someone who had made the journey many times. He had formed a mental image.
The mental image had not included the noise.
"Brilliant isn't it," his father said, appearing beside him with the easy warmth of a man who had been looking forward to this moment for some time. He was looking at the platform with the expression he wore when something genuinely pleased him, which happened often because Edouard Flamel was, constitutionally, someone who found the world genuinely pleasing. "I always wanted to go. Your grandmother wouldn't hear of it. Private tutors." He shook his head sorrowfully. "No train."
"You had better magical education than anyone on this platform," Cael pointed out.
"That is completely beside the point," his father said, with great dignity.
Albion surveyed the platform from Cael's shoulder with the expression of a creature cataloguing territory. Several nearby owls noticed him and went very still. A cat on top of a nearby trunk took one look and relocated to the other side of the trunk. A boy with red hair and something on his nose walked past, did a double take at Albion, and walked into a post.
Caedmon materialized at Cael's other side. He was still laughing about the 1887 horse story. He looked at the platform with the bright eyes of someone for whom six centuries had not dimmed the capacity for finding things interesting, which was perhaps his most extraordinary quality in a family full of extraordinary qualities.
"Right then," he said, and put a hand on Cael's shoulder. He said something else, quietly, in the old language — the one that predated French and English both, the one the family used for things that mattered. Cael's magic speak translated it without effort.
You are the best of all of us, boy. Go show them what that means.
Cael looked at his grandfather.
Caedmon grinned — the grin of a man who had ruled an empire for centuries and had recently decided that being an embarrassing grandfather was considerably more enjoyable. "Also write. Every week. Or I'll send a howler."
"You don't know how to send a howler," Cael said.
"I'll learn," Caedmon said pleasantly. "Specifically for this purpose."
Cael believed him entirely.
Nicolas had been hovering for the past several minutes with the energy of someone who had something to say and was trying to determine the right moment. He abandoned waiting for the right moment entirely and simply pulled Cael into a hug that was considerably more enthusiastic than dignified and went on for long enough that Perenelle put her hand on his arm.
"Nicolas," she said.
"I know," he said. He did not let go immediately.
"Nicolas."
He let go. He looked at Cael with six hundred and fifty years of life behind his eyes and the expression of a man for whom this particular moment — this specific morning, this boy, this platform — was the finest thing those six hundred and fifty years had produced.
"Every week," he said. His voice was entirely steady. This was impressive.
"Every week," Cael said.
Perenelle took his face in both her hands the way she had done since he was small enough that she had to crouch to do it. Now she barely had to look down. She looked at him for a moment — warm and steady and entirely herself — and then she kissed his forehead once, precisely, the way she did most things.
"Eat properly," she said. "The chocolate is supplementary."
"I know," Cael said.
"You don't know," she said, with great affection. "But you'll learn."
She let him go.
His mother was last.
The platform moved around them — steam and noise and families and owls and the great red train breathing steadily at the edge of it all — and Seraphine stood in the middle of it and looked at her son and the platform might as well not have existed.
She didn't fix his collar again. She didn't give him a list. She didn't say everything she could have said, everything that six centuries of waiting and eleven years of loving this specific impossible child had accumulated into something too large for a train platform on a Tuesday morning.
She pulled him in instead. Both arms. Properly. The way she hadn't since he was small, the way she was always too careful about because she was his mother and she was teaching him to be strong and strong people didn't cling.
She clung, briefly, fiercely, with the particular desperation of someone who had waited five hundred years for something and was now watching it walk onto a train.
Then she let go.
"Be good," she said.
"I'll try," he said.
Something moved in her eyes. "Be brilliant then. That comes more naturally."
He smiled at her. She almost smiled back. Then she straightened — every inch of her composed and fierce and entirely herself — and nodded once, and he picked up his bag and turned toward the train.
He didn't look back. She had told him once, years ago, when he was small. Walk forward, she'd said. The people who love you will still be there when you turn around later. Don't look back from doorways.
He walked forward.
The compartment he found was empty and toward the middle of the train, which suited him. He stowed his trunk, settled Albion on the luggage rack — Albion inspected it thoroughly, found it structurally acceptable, and arranged himself across it with the air of something claiming territory — and sat down by the window.
Astrape took the seat beside him.
Excalibur leaned against the seat opposite with the quiet certainty of something that had been leaning against things for nine hundred years and knew how to do it properly.
Outside the window the platform was still full. He found his family without trying — his grandfather's hat visible above most of the crowd, his grandmother's steady posture, his father's easy stance, his mother standing very straight and very still.
Caedmon was somehow still telling the 1887 horse story to a bewildered looking family nearby. They hadn't asked for it. They were getting it anyway.
Cael watched until the train shuddered and began to move, and the platform slid slowly backward, and his family grew smaller, and then smaller still, and then the barrier appeared and swallowed them and there was only the grey London sky and the tracks ahead.
He opened the chocolate.
Albion's head appeared over the edge of the luggage rack with impeccable timing.
"Supplementary," Cael told him.
Albion stared at him.
Cael gave him a chocolate frog. Some principles were better discussed after breakfast.
He was on his fourth frog and Albion was engaged in what appeared to be a deeply personal dispute with his own tail when the compartment door slid open.
A girl stood in the doorway with the expression of someone who had already been up and down this train twice and was running out of patience with it. Bushy brown hair, bright eyes that moved fast and catalogued faster, a slight breathlessness that suggested she'd been hurrying.
"Have you seen a toad?" she said. "A boy named Neville's lost one."
"No toad," Cael said. "Sorry."
She nodded and began to turn away.
Then her brain caught up with her eyes.
She turned back. Slowly. Her gaze moved across the compartment with the focused inevitability of someone whose cataloguing system had just flagged something significant and was going back to examine it properly. The luggage rack — where Albion had paused his tail dispute to watch her with one golden eye. The seat beside Cael — where Astrape sat surrounded by a faint halo of silver electricity, crackling softly. The belt — where the Grimoire glowed with quiet gold persistence. The seat opposite — where Excalibur leaned with nine centuries of patience.
Then his face.
Her mouth opened.
"Prince C—"
The silencing field went up without thought — wandless, wordless, containing the sound within the compartment so efficiently that the word simply stopped existing outside it. She froze. Her hand went to her throat.
"Sorry," Cael said immediately, dropping it. "Sorry. Reflex." He held out the bag. "Chocolate frog?"
She stared at him.
"You're—" she started, much quieter now.
"A student," Cael said. "First year. Same as you, I'd imagine." He offered the chocolate again. "Please sit down. You're making Astrape nervous."
Astrape, who had never been nervous in her life, crackled with silver lightning in a way that suggested she found this characterization inaccurate.
The girl sat down. She did it with the careful deliberateness of someone whose legs had made the decision slightly ahead of her brain. She took the chocolate frog. She held it without eating it. She was looking at Albion.
"Is that," she said, with great precision, "a dragon."
"Yes. Albion." Albion, hearing his name, looked down from the luggage rack with the expression of someone who had decided she was probably acceptable. "He's friendly."
"He's golden," she said.
"Yes."
"And he has four legs. And separate wings."
"Yes."
"Most dragons have two legs and wing-arms," she said, in the tone of someone reciting something they had read and were now revising in real time. "I read that in Dragon Species of Great Britain and Ireland."
"Most do," Cael agreed. "Albion's a bit different."
She processed this. Then her eyes moved to Astrape, who crackled once — a small sharp arc of silver that jumped between her primary feathers and made the girl's hair lift slightly with static.
"The owl," she said.
"Astrape. Thunderbird blood. She can't really help the lightning, it's involuntary." He paused. "Mostly."
Astrape looked at the window with the dignity of someone declining to confirm or deny.
The girl's eyes moved to the Grimoire. Then to Excalibur. They stayed on Excalibur.
"Is that a sword."
"Yes."
"You brought a sword to Hogwarts."
"It's a family heirloom," Cael said, with the complete unconcerned simplicity of someone for whom this was simply true and had never been anything other than true.
She looked at it for a long moment. At the blade. At the hilt. At the way it leaned against the seat as though it belonged there, which it did, because it belonged wherever he was, because it had belonged with his family since Arthur and that was simply how things were.
"Is that Excalibur?" she said.
Her voice had gone very quiet.
"Yes," Cael said, already looking back at his chocolate.
Silence.
"You just—" She stopped. "You said yes."
"It is Excalibur," he said, mildly puzzled by the need for elaboration. "So yes seemed right."
She stared at him with the expression of someone whose internal filing system had just received a folder it had no cabinet for. She stared at the sword. She stared back at him. She opened her mouth and closed it once.
"I'm Hermione," she said finally. "Hermione Granger."
"Cael," he said. "Just Cael, on this train. Please."
She nodded. Then, because she was clearly someone whose brain did not have an off switch regardless of circumstances — "I saw you. In the muggle news. You were at a state function. In London."
"Probably," he said.
"There was quite a lot of coverage. More than usual." She was watching him carefully with the focused attention of someone who had learned that the most interesting information lived in the gaps between what people said. "Was there a reason for that specifically?"
Cael's hand stopped moving toward the chocolate bag.
Something crossed his face. Brief and entirely unmistakable. His ears went slightly pink.
"Not particularly," he said, in the tone of someone who had decided that was the answer they were giving and no further questions would be entertained.
Hermione looked at him for a moment with the expression of someone filing an answer under incomplete and marking it for future review. She said nothing further about it. For now.
"Right," she said pleasantly.
He offered her another chocolate frog. She took it this time.
"You cast that spell without a wand," she said, after a moment. "Or words."
"Yes."
"How?"
"Some people can," he said simply. "Wands are a European tradition mostly — British, French, parts of Eastern Europe, North America. Other magical communities use different methods. Chants. Focus stones. Talismans. In India and parts of Africa and Japan the magic works through completely different channels." He touched the Grimoire briefly. "My focus is this."
She looked at the glowing book with the expression of someone adding an extremely large item to an already substantial list.
"Can I—"
"No," he said. Warmly. Clearly. "It's personal."
She accepted this with visible effort and the quiet dignity of someone who respected information being handled carefully even when she personally wanted all of it immediately.
"Are there other abilities?" she asked. "That are unusual."
"Some," he said. Which was true and told her nothing and he said it with a warmth that made the door feel friendly rather than closed.
She recognized the door. She let it be.
"What house do you think you'll be in?" she said instead.
"Gryffindor," he said.
"How do you know?"
He thought about it for a moment. "The flag looks like my royal flag," he said simply.
Hermione stared at him. "That's not really how it works."
"It'll work out," he said, and reached for another chocolate frog.
She looked at him for a long moment with the expression of someone filing this answer alongside the pink ears and the incomplete explanation and the sword and the dragon and the glowing book, into a growing folder labeled Cael — ongoing.
Albion descended from the luggage rack at this point with the deliberateness of something that had made a decision. He landed on the seat beside Hermione — she went very still — and examined her at close range with one golden eye, with the focused assessment of a creature that took these evaluations seriously.
"He's deciding," Cael said.
"About what?"
"Whether he likes you."
"How will I—"
Albion headbutted her hand. Once. Firmly. Then climbed back to the luggage rack and resumed his tail disagreement as though the entire interaction had not occurred.
Something shifted in Hermione's expression. The cataloguing paused. Just for a moment, just long enough for something genuine to come through — delight, uncomplicated and real, the kind that didn't perform itself.
"He's wonderful," she said.
"Don't," Cael said. "He's already impossible."
She laughed. Properly. It changed her face entirely.
They changed into their robes in turns without discussing the arrangement — it was simply the obvious thing to do and they were both people for whom obvious things did not require negotiation. Hermione stood at the compartment door with her arms folded and an expression that made two older students who had slowed down to look through the glass reconsider their life choices. Astrape sat on her shoulder during this time and crackled with silver lightning at anyone who looked twice.
"She's very useful," Hermione said, when Cael emerged.
"She knows," Cael said.
Astrape looked at the corridor with the quiet satisfaction of a job completed to personal standards.
Outside the windows Scotland had appeared at some point while they weren't looking — dark hills and silver lochs and sky going deep purple at the edges, wild and large and very certain of itself. The train moved through it with the ease of something that had done this journey many times and loved it every time.
Cael ate chocolate. Hermione read a textbook and asked questions about things that interested her and accepted partial answers on things that were personal with the grace of someone who understood the difference. Albion slept. Astrape watched the dark hills pass with the focused attention of a creature that took landscapes seriously.
It was, Cael thought, a perfectly good start.
When the announcement came Hermione put her book away and looked at the window with an expression she was doing her best to keep neutral and not entirely succeeding.
"Nervous?" Cael asked.
"A little," she said. Then, more honestly: "Quite a lot."
"It'll be fine," he said.
"You can't know that."
"I can't not know it either," he said.
She thought about this. It seemed to help, which had been the intention.
The lights of Hogsmeade station appeared in the darkness outside. The train began to slow with the comfortable inevitability of something arriving somewhere it had always been going. Albion woke. Astrape stood. Excalibur caught the light from the window and held it — gold and steady and entirely patient — as Cael picked it up the way he always picked it up, the way he had since he was two years old, without thinking about it because there was nothing to think about.
Hermione watched him do it.
"Just Cael," she said quietly. Reminding herself.
"Just Cael," he agreed.
The train stopped. Cold Scottish air came flooding in from the corridor. And somewhere out in the dark beyond the platform, enormous and warm and entirely certain of itself:
"Firs' years! Firs' years over here!"
Hermione picked up her bag. Cael picked up his. Albion arranged himself across his shoulders with the dignified authority of something that had decided this was its position and intended to keep it. Astrape crackled once, briefly, silver in the dark.
They stepped out onto the platform together into the cold and the noise and the beginning of everything.
