The silence that followed lasted approximately four seconds.
Then Ron Weasley, from somewhere in the back row, breathed, "Wicked," and the whole class exhaled at once, like a held note finally released.
Cael was already writing.
Not with his hand — his hand was resting flat on the desk, perfectly still. The Grimoire was writing itself, the quill moving in quick, sure strokes across parchment that seemed to drink the ink, recording the last residue of the transformation in old Fey script: diagrams, structural notations, the precise architecture of the metamorphic instruction he had given his own body forty seconds ago. He tilted his head, read one line, added a small correction in the margin in his own hand, and closed the cover.
The Grimoire glowed faintly at its gold-cornered edges. Then it stilled.
McGonagall had turned back to the blackboard.
She was writing the theory of cross-species transfiguration in precise, measured strokes, each letter exact, chalk never squeaking. Every student in the room was watching her write — every student except Hermione, who was watching Cael with the focused attention of a scholar who had just discovered a primary source in a used bookshop and was trying to read the spine without appearing to stare.
"You're writing about it," she said, under her breath.
"The Grimoire writes itself when I observe magic," Cael said, equally quiet. "I just add the notes it misses."
"It writes itself."
"Fey magic. It's connected to me — when I understand something, it records it."
Hermione opened her notebook, made a small, complicated sound — the specific sound of someone whose organisational framework has just been challenged by evidence — and wrote Fey Grimoire — autonomous notation — cross-reference magic texts — ask later (PRIORITISE!!!) written in capital careful underlined letters. She underlined prioritise twice. Then she added a small star.
Up at the board McGonagall spent the next twenty minutes walking them through the foundational principles of transfiguration: the necessity of holding a complete and unbroken mental image, the biological complexity that made each species its own unique problem, the years of dedicated study required before any competent witch or wizard ought to attempt even a partial transformation. She demonstrated with a matchstick. It became a needle in under two seconds — clean, silver, catching the light from the windows like a small cold star.
The class was suitably impressed.
McGonagall turned to face them. Her eyes moved — briefly, precisely, the way a hawk moves its head to confirm a location — to the first row.
"Before we proceed," she said, "I believe this class has a question they are collectively too polite to ask."
Heads turned toward Cael with the unanimity of a tide.
He looked up from the margin note he had been adding, found twenty pairs of eyes on him, and said, "Oh. Yes, alright."
McGonagall folded her hands in front of her. "Perhaps you might explain, for everyone's benefit, how a first-year student with no formal magical education performed a complete animagus transformation on his first day of term."
She said it without accusation. Without censure. She said it like a scientist presenting a specimen for the room's consideration — already certain of what she was looking at and simply wanting the name confirmed.
Cael closed the Grimoire. "Two things," he said. "The first is that I am a metamorphagus."
The room went quiet in a different way — not the stunned silence of thirty seconds ago, but something more careful, more attentive. Like an audience leaning forward.
"A natural one," he continued. "Controlled and conscious. My body already knows how to transform — it is simply part of what I am. The ritual process exists because it teaches a body to do something it does not naturally do. Mine already does it. The ritual would be like teaching a fish the theory of swimming."
"And the second thing?" McGonagall asked.
"Magic Speak." Cael folded his hands on the desk, unhurried. "I can communicate in magical languages. Not a blanket ability — each creature species has its own specific language, and I speak them individually. But the Fey tongue is one, and it is, in essence, the language of instruction. It tells living things what to be. I spoke two words in Fey to my own body — animagus transformation — and my metamorphagus form provided everything else. It was less a transformation and more a conversation."
Harry Potter, in the third row, was staring with his mouth open in a way he was entirely unaware of. This was, Cael suspected, a face he would make rather often this year.
Ron had his quill hovering half an inch above blank parchment — the specific pose of someone taking notes mentally and intending to write them up later, which was Ron's version of academic engagement.
Seamus Finnigan, two seats left of Ron, whispered something to Dean Thomas that contained the words "two words" and "just two words."
McGonagall allowed the murmuring to last three seconds, precisely, before the room remembered itself.
"So," she said, and she was not quite smiling — it was something more restrained than a smile, something that lived in the corners of her eyes only, "you bypassed years of mastery and months of ritual preparation by giving your metamorphagus body a verbal instruction in a dead magical language."
"More or less, yes."
"In my classroom."
"Yes."
"On the first day of term."
"The magic was fascinating." A pause. "I apologise for any disruption."
McGonagall regarded him for a long, steady moment — the gaze of someone composing a very particular response with the same care she gave her chalk letters.
"You transformed into a golden manticore with silver wings and an amethyst poisonous tail," she said, "in the middle of my introductory lesson."
"Yes."
"The disruption," she said, "was considerable."
"Yes."
"I am," she said, after the barest pause — a pause that contained several things— "Impressed."
She turned back to the blackboard.
"That said," she added, without turning, "the rest of you will be beginning with matchsticks. Open your textbooks to page two."
Hermione already had.
She had four new tabs.

The lesson continued without further transformations.
Cael worked through the matchstick exercise alongside everyone else, which was — a piece of cake.
Neville Longbottom's matchstick, two seats down, melted slightly across the middle — not what was asked for, but an interesting result. More force than control; the magic was there, running hotter than he knew. Cael said as much, quietly enough that only Neville heard, and Neville looked startled, then grateful, and his next attempt produced something that was at least attempting to be a needle.
"The tip is better," Cael said.
"Still looks like a very determined piece of wood," Neville said sadly.
"Give it another go. Think cold. Needles are cold things."
Neville frowned in concentration. The matchstick on his desk shivered — and then, slowly, the tip went silver.
It was half a needle. But it was half a needle more than it had been.
Neville stared at it with an expression of cautious, disbelieving wonder, as though he expected it to change its mind.
Hermione's needle was perfect by her third attempt. She picked it up, examined it at eye level, set it down, and made a small annotation about what had changed on the second try versus the third. Then she glanced at Cael's matchstick, which had become a needle on the first attempt and had since been left alone while he read about something else.
"You're not going to try for anything more complicated?" she asked.
"It would feel like cheating," he said, and he meant it.
She considered this. "That's surprisingly principled."
"McGonagall is teaching the class, not just me. Turning the matchstick into something elaborate would make it about me again. It's already been about me once today."
Hermione looked at him for a moment. Then she looked back at her needle and added another note. This one had a small asterisk and the words contextual restraint — deliberate.
When the bell rang, the class gathered their things with the particular energy of people who had witnessed something and were not yet sure what to do with it. The conversations that broke out into the corridor had the quality of pressure releasing — everyone suddenly able to say what they had been holding in for an hour.
"— just said two words—"
"— a manticore, a manticore, they have venom in the tail, Seamus—"
"— knew it was a metamorphagus thing, obviously, I knew that—"
"You absolutely did not know that, Dean—"
McGonagall remained at her desk.
"Mr. Flamel-Pendragon," she said, without raising her voice, without looking up from her papers.
Cael was already on his feet. "I will catch up with you," he said, to the others.
Harry nodded, easy about it, and headed for the door. Ron followed, already mid-question about whether the matchstick-to-needle was graded on appearance or metallurgic accuracy. Hermione paused at the threshold — a visible pause, the kind that had an internal argument attached to it — and looked back.
"I will tell you everything," Cael said.
"Everything," she said.
"Everything."
She went. Slowly. But she went.
The door swung shut. The classroom settled into the particular quiet of rooms recently vacated. Morning light came through the high windows at a sharp September angle, making long pale rectangles on the stone floor. Albion, who had spent the entire lesson sleeping under Cael's bench and whom McGonagall had made the executive decision not to acknowledge, stretched all four legs in sequence, rose, and walked to stand beside Cael's feet with the gravity of someone arriving at an important meeting they had always planned to attend.
McGonagall set down her quill.
"I am going to ask you something," she said, "and I want you to answer honestly, rather than diplomatically."
"Alright."
She looked at him steadily. "Have you already covered the Hogwarts curriculum?"
Cael considered this — genuinely, not as a performance of consideration, but as a question that deserved an accurate answer. "Most of it. Not all. There are areas of magical theory the upper years cover that I have not formally studied, and there are practical subjects where I have no structured instruction at all — Herbology, certain branches of Care of Magical Creatures, Potions, the practical frameworks of Flying." He paused. "But the majority. Yes."
"Transfiguration."
"My mother is a grimoire practitioner. The theoretical framework of transfiguration is embedded in Fey magical structure — I have lived with it since I was old enough to read her notes." Another pause; this one was more careful. "I could still learn from your classes, Professor. You teach the reasoning behind the technique, not merely the technique. The why underneath the what. That is what I lack the most."
Something shifted in McGonagall's posture — a small, private thing, barely visible. The adjustment of someone who has been told something accurate and receives it as such.
"There is," she said, "another metamorphagus at Hogwarts. A seventh-year student. She has been studying the theory of her own ability for five years, and she has never managed a fully controlled transformation."
Cael said nothing. He understood this was not the whole of what she was about to say, and that the appropriate response to an unfinished sentence was silence.
"Her name is Nymphadora Tonks," McGonagall said. "She goes by Tonks. She is — energetic." The word carried a great deal of unspoken information. "I would like, with your agreement, to introduce you. Not to ask you to instruct her — I would not place that responsibility on an eleven-year-old student. But to speak with her, if you are willing. One metamorphagus to another."
"Of course," Cael said, without hesitation. "I would be glad to."
The shift in McGonagall's posture this time was slightly more pronounced: the particular straightening of someone whose plan is proceeding along better lines than they had allowed themselves to hope.
"Good." She allowed it to settle for a moment. "There is also something else I would like to discuss — but I think it would be best discussed together with the Headmaster and Professor Flitwick. Would you be available this afternoon, after your last lesson?"
Cael looked at her. In the angled morning light, his gold eyes caught the window and held it — warm metal, not cold, the colour of the last hour before sunset. "Yes. I am available."
"Three o'clock. The Headmaster's office."
Albion, at Cael's feet, made a sound — small, precise, the draconic equivalent of clearing one's throat.
"He says," Cael said, with a trace of amusement he did not particularly suppress, "that he would also like to attend."
McGonagall looked down at the dragon: cat-sized, golden, regarding her with large and entirely too knowing eyes, with the patient composure of someone who has already decided the outcome of this conversation and is simply waiting for the humans to catch up.
"He may attend," she said, with the full gravity of someone formally admitting a dragon to a faculty meeting.
Albion inclined his head once. Minimally. As though this were no more than his due.
★ ★ ★
The morning moved through Charms and History of Magic and a Potions lesson that Cael found genuinely interesting in ways Snape appeared both to notice and to find slightly irritating, in the specific way that a man who has decided to dislike something finds it inconvenient when the something turns out to have merit. Though he seemed to have some—opinions—about Harry.
Cael did not try to be interesting. He simply paid attention and asked two questions — about the precise role of heat transference in the early stages of the Forgetfulness Potion, and about whether the stirring direction had a mechanical or a symbolic function — that were, unfortunately for Snape's prepared narrative about pampered princelings and inherited arrogance, exactly the right questions.
Snape answered them. Both times. Without expression. In the voice of someone providing information against their better judgment.
He deducted two points from Gryffindor at the end of the lesson for "unnecessary verbosity." No one, including Cael, was entirely sure which question had been the unnecessary one.
History of Magic was Professor Binns, who had died at some point in the previous century and not allowed it to interrupt his schedule. He spoke about goblin rebellions the way sediment forms — slowly, consistently, without apparent awareness of the effect. He did not notice his students. His students did not notice him. Cael tried to focus and was… asleep in minutes. Hermione took notes on the notes. Ron was also asleep inside four minutes, which was, by any honest accounting, impressive.
Lunch was loud and good. Albion ate an entire roasted chicken and part of a bread roll and then sat on the table looking fundamentally satisfied with himself. Astrape had her favorite bacon and tried not to acknowledge Albion.
Fred Weasley, from three seats down, watched this and said, with sincere admiration, "Mate. That's the dream."
"He has a faster metabolism than a small country," Cael said.
"All the best people do," George said.
"We've been thinking," Fred said, leaning forward with the air of a man presenting a proposal he has already fully committed to, "about the kitchen."
"I have no thoughts about the kitchen," Cael said pleasantly.
"Interesting," George said. "Because the kitchen has some very interesting thoughts about Filch."
"I was not involved in any conversation about Filch and his cat."
Hermione, without looking up from her book: "Cael."
"I am not involved," Cael said.
"No one said anything about the cat," Fred said, nodding. "Very inspiring."
"We should all take lessons," George agreed.
"I am going to eat my lunch," Cael said, and ate his lunch, and did not look at the twins, and absolutely did not, when Hermione looked up at the clock and then back at her book, extend one hand in their direction beneath the table to accept the small folded plan that George pressed into his palm.
He did not do that.
