"Magic isn't an opponent you conquer," Dumbledore's voice drew him back. "Treat it as a friend. Have a conversation with it. The most powerful magic makes the world work alongside you."
Makes the world work alongside you.
Regulus turned the phrase over in his mind.
He agreed completely. He'd reached the same conclusion on his own. A wizard's will and magic shaped the world, and the world answered in kind.
The principle was sound. But Dumbledore could probably do it. He couldn't. Not yet. Not even close.
"Take potions as an example." Dumbledore shifted angles. "Professor Slughorn teaches you to control the heat, prepare ingredients, mind the direction and number of stirs. But the finest potions, Felix Felicis among them, require a window where you let the magic ferment on its own. You can't rush it. Can't force it. You wait for every component to find its place."
His fingers traced invisible circles in the air, stirring an unseen cauldron.
"Magic works the same way. Not every spell needs to be pushed to maximum effect. Sometimes leaving room, giving the magic space to breathe, is the higher art."
Regulus thought about his own casting habits. Precise output calculations, strict effect control, every drop of magic put to its sharpest use.
Nothing wrong with that. It was efficient and effective.
But Dumbledore was describing another possibility. Some magic didn't need to be pushed to the brim. A little room left over could trigger effects that were more natural, more lasting.
"That doesn't mean doing nothing," Dumbledore continued. "It means doing what needs doing, then letting things take their course. When facing darkness, the question isn't how much I can destroy. It's how much I can illuminate."
Regulus sat with that in silence. The idea was abstract. He needed time to digest it.
The portraits listened quietly. Phineas Black watched Dumbledore with a complicated expression.
He was probably thinking: I already consider this boy devious, and you're pouring all this wisdom into him? Regulus Dumbledore, is it now?
Fawkes let out a soft trill and glided down from his perch, landing on the edge of the desk. He tilted his head at Regulus, dark bright eyes reflecting the boy's silhouette.
Regulus's mind wandered for a moment. Fawkes's gaze looked a lot like Dumbledore's.
"What I've shared today," Dumbledore leaned back, his smile warming again, "is just that. Sharing."
Then his tone shifted. "Everyone has to find their own path in the end. Other people's experience is a reference, not a blueprint."
He raised a hand. The teapot on the desk tilted of its own accord, topping off both cups with fresh hot tea.
"But for now, at least, I think your direction is right." He picked up his cup. "Keep walking, Regulus. Bring your reason with you, and your wonder. Bring your calculations, and your reverence. Magic won't disappoint a wizard like that."
Regulus lifted his own cup. The tea had cooled, but it still carried a faint fragrance as he drank.
It struck him then that Dumbledore hadn't taught him a single spell today. Hadn't shared any secret knowledge.
Everything he'd said was personal insight. Distilled experience. The philosophy of magic.
And it was worth more than any specific spell could have been.
What Dumbledore had given him was framework and his perspective. A way of understanding how magic and the world related to each other. With that, he could derive countless applications on his own.
The treasure was out there. Dumbledore hadn't taken him to it, but he'd handed him a map and a compass.
"Thank you, Professor." The words came out solemn, and he meant every one.
Dumbledore blinked, the corners of his mouth curling beneath his beard.
"You're welcome." His voice turned lighter. "Honestly, I enjoy conversations like this. Students at Hogwarts who are ready for them... there aren't many."
A portrait on the wall let out a small huff. "The last one who talked like this was..."
"Dilys." Dumbledore cut her off gently.
The portrait of Headmistress Dilys pursed her lips but said nothing more.
Regulus had a fair idea who they'd actually been thinking of. Tom Riddle.
He drained the last of his tea, set the cup down, and rose.
"I should head back, Professor. I need to sit with everything you've said."
"Of course." Dumbledore stood as well, coming around the desk. His tone turned wistful. "You're sure you won't try a Cockroach Cluster? Listen, they really are..."
"No." Regulus didn't hesitate.
Dumbledore clicked his tongue. "Shame."
Regulus let that pass. He gave a slight bow. "Thank you again, Professor. I've gained a great deal."
"Off you go." Dumbledore smiled.
Regulus nodded, offered a small bow to the portraits along the wall, dipped his head to Fawkes in farewell, and turned for the door.
His hand closed around the handle when Dumbledore's voice came from behind him.
"Regulus."
He looked back.
"Remember," the Headmaster said, standing where he was, eyes steady on him, "whatever path you choose in the future, Hogwarts will always be your school. And school is a place where you're allowed to make mistakes."
There was more in those words than their surface. Regulus heard it clearly.
"I understand, Professor."
He pushed through the door. The spiral staircase carried him slowly downward, depositing him in the eighth-floor corridor.
Inside the office, Dumbledore hadn't moved. He stood watching the closed door.
The portraits began murmuring among themselves, every conversation circling the Slytherin boy who'd left.
Phineas Black finally set down his newspaper. "You're investing a great deal in him, Albus."
"I invest a great deal in all my students, Phineas." Dumbledore walked back behind his desk and sat.
"But you don't talk to all of them this much, or this deeply."
Dumbledore smiled. His hand drifted toward the Cockroach Clusters, hesitated, then pulled back. He plucked a Sherbet Lemon from the silver tray instead and popped it into his mouth.
"Because not all of them are ready to hear it." The candy made the words slightly muffled.
Fawkes soared back to his perch, spread his wings, and let out a long, ringing call.

At lunch, the Great Hall smelled of roast beef and mashed potatoes.
Regulus sat down at the Slytherin table, fork in hand, mind still turning.
He distilled Dumbledore's words down to a single point.
Magic needed breathing room.
Don't push to full power. Surrender a portion to magic itself. Do what needs doing, then let events unfold.
He understood the logic. The question was where the balance point lay.
Control came naturally to him. Leaving slack, letting magic breathe, felt like programming a precision instrument to tolerate error on purpose.
But it was worth trying.
Dumbledore had been at this a long time. Following in his footsteps wouldn't steer him wrong.
He cut a piece of beef and chewed, eyes sweeping the hall. Gryffindor's table was the loudest. Ravenclaw ran quieter. Hufflepuff rang with scattered laughter. And here at Slytherin, the stillest of them all.
Hogwarts was a good place.
The professors were good people. McGonagall, Flitwick, Sprout, Slughorn, and now Dumbledore himself. What they'd given him went beyond spells and recipes. They'd taught him ways of seeing magic, approaches to solving problems, even lessons about what kind of person to be.
He thought of Dumbledore's parting words. Whatever path you choose in the future, Hogwarts will always be your school. And school is a place where you're allowed to make mistakes.
That had sounded less like advice and more like permission. Preemptive understanding, offered before it was needed.
Dumbledore knew the Black family's position. The tide of Pure-blood houses drifting toward Voldemort was no secret to the Headmaster.
And still he'd chosen to share those things with Regulus. To express approval and expectation.
The reason wasn't talent alone. Deeper down, it was probably that in the long contest between Dumbledore and Voldemort, both sides had their eye on him.
Seen through a rational lens, the Headmaster was making an early play. An investment. Adding weight to his own side of the scale.
The thought made Regulus shake his head faintly. He didn't resent being invested in.
At least Dumbledore's currency was wisdom. His method was guidance.
That beat most other forms of investment by a wide margin.
He swallowed the last bite and took a sip of pumpkin juice.
"Regulus!"
The call came from the entrance. Cuthbert and Alex walked in, half-melted snowflakes clinging to their hair, cheeks flushed red from the cold, eyes bright.
They reached the table. Cuthbert dropped onto the bench across from him. Alex was more careful, shaking the snow off his robes before sitting down.
"Snow's stopped, sun's out, gorgeous weather." Cuthbert grabbed a roll and stuffed it into his mouth. "Want to come hang out?"
"We could have a snowball fight," Alex added quietly.
Regulus looked at them.
Cuthbert's invitation was casual. Alex's suggestion was light.
He knew what they were thinking.
He almost never joined in things like this. Always off to the library, the Room of Requirement, practicing magic. To them, inviting Regulus to play was like inviting a professor to a student party. It didn't compute.
They were asking just to ask.
But today felt a little different.
Today, he wanted to try leaving room. Not filling every hour. Not doing everything for some defined purpose.
"Sure," Regulus said.
Cuthbert's mouth hung open, bread crumbs stuck between his teeth.
Alex looked up, eyes wide.

The Headmaster's office.
Dumbledore stood at the window, a cup of honey tea in his hand.
Below, three figures moved across the castle grounds.
Two ran ahead, shoving each other through the snow. The third walked at an even pace behind them, pausing now and then to look around.
They reached the edge of the Black Lake, crouched by a hole in the ice, stayed for a long while, then stood and headed back.
Dumbledore's lips curved upward. He raised the cup and drank. Sweetness dissolved across his tongue.
He turned, walked back to the desk, and set the cup down. On his perch, Fawkes gave a quiet trill, as if saying something.
"I know, Fawkes." Dumbledore's voice was soft. "Give him time. And give magic a little time, too."
