In the Potions classroom deep beneath the castle…
A Slytherin student watched as a Gryffindor at the next table nearly caused his cauldron to explode due to a mistake. His first instinct wasn't to sneer.
Instead, he frowned and muttered a quiet reminder, "Idiot. The skin of an African Tree Snake has to be sliced counterclockwise. It's written clearly in the book."
The Gryffindor froze for a moment, then scratched his head. For the first time, he gave Slytherin a sincere, grateful smile. "Thanks, mate."
In a quiet corner of the library…
A Gryffindor Quidditch player noticed a Slytherin struggling over an Ancient Runes assignment. He approached—not to provoke, but awkwardly offering help.
"I heard Lord Lin Sen started with this book—Advanced Rune Translation. It's tough, but… want to try working through it together?"
The Slytherin looked up at the slightly goofy yet utterly sincere face in the sunlight. After a long silence, he gave a small nod.
Scenes like these became more and more common.
There was no grand reconciliation ceremony. No impassioned speeches.
Yet the thousand-year divide between Slytherin and Gryffindor—once as vast as a chasm—began, under the sunlight of this new era of equality and shared pursuit of truth, to slowly melt away.
Until one day…
Standing by the window of the Headmaster's office, Dumbledore saw an older Gryffindor student walking side by side with a Slytherin, laughing as they headed toward Hogsmeade. As they walked, they passionately debated an innovative application of the Memory Projection Charm.
This wise old man—who had weathered countless storms and witnessed two wizarding wars—felt his eyes grow moist.
He knew.
The thousand-year debate between Salazar Slytherin and Godric Gryffindor had finally, at last… found its perfect answer.
And the one who gave that answer…
Was the student he was most proud of—and the one he understood the least.
At that moment, a true rebirth of Hogwarts quietly arrived.
Under the light of this new era, Hogwarts' reconstruction and reform flourished at an unprecedented pace.
The "handshake" between Slytherin and Gryffindor became a symbolic event, marking the complete end of an age defined by prejudice and division.
And once everything gradually settled into order…
A proposal—jointly initiated by the Hogwarts Board of Governors, the new Minister for Magic Kingsley Shacklebolt, and Daphne Greengrass, leader of the "New Nobility Council," and unanimously approved by all members of the Order of the Phoenix and Hogwarts faculty—was formally put forward.
To honor Lin Sen—for his immeasurable, indescribable, immortal contributions to Hogwarts, the British wizarding world, and beyond—
They would erect an eternal statue of him within Hogwarts Castle.
The proposal met no resistance.
Everyone believed it was only natural… even insufficient.
On the final day of the term…
The Great Hall was once again filled with people.
But this time, it was not for celebration, nor for judgment.
It was to witness history.
At the front of the hall, where the staff table once stood, four lifelike statues stood quietly—Godric Gryffindor, Helga Hufflepuff, Rowena Ravenclaw, and Salazar Slytherin.
At the very center, the most honored position, was concealed behind a massive curtain embroidered with the Hogwarts crest.
Dumbledore, the legendary headmaster nearing retirement, stepped slowly before it.
Looking out at the sea of excited, reverent, expectant faces, a gentle smile appeared on his aged face.
"For a thousand years," he said, his voice imbued with magic, "these four great founders have stood as the foundation and glory of Hogwarts."
"They left us this sanctuary of knowledge."
"And today," his voice turned solemn and grand, "we welcome… the fifth—and most special—guardian of Hogwarts."
"He surpassed all legends as a student."
"He ended the darkest era by his own hand."
"With wisdom and generosity, he ushered in a new age of light."
"His name is—"
Dumbledore's voice rang out, each word filled with power:
"—Lin Sen!"
With a sharp wave of his wand—
The curtain parted.
And the moment the statue was revealed, the entire hall erupted into thunderous, unending applause and cheers.
There stood a new statue—crafted from pure magical gold and eternal mithril.
It was Lin Sen.
One hand rested behind his back, while the other gently supported an open book, symbolizing boundless knowledge and truth. His gaze was calm, fixed on the distance; within those deep eyes seemed to lie the stars of the universe, carrying a serenity and wisdom beyond the mundane world.
The statue did not depict his world-shattering power.
Nor his overwhelming dominance.
What it showed… was an eternal seeker.
A guide of civilization.
From this day forward, it would stand here forever—beside the four founders—guarding this ancient castle.
For generations of Hogwarts students to admire, learn from, and follow.
Amid the roaring cheers…
The man at the center of it all, Lin Sen himself, seemed… distracted.
He had handled the aftermath of the war, founded the Institute of Arcane Studies, and set the tone for a new era of peace and justice.
He had refused every position offered by the world, and declined Dumbledore's request to become headmaster.
Because he had realized something.
There was still one very important thing he hadn't done.
He hadn't graduated from Hogwarts.
And so, at the start of the new school year…
As the Hogwarts Express once again sounded its familiar whistle and carried students toward the reborn castle—
Before the stunned gaze of new students, and the fervent reverence of the old—
Lin Sen, the man hailed worldwide as a "god," calmly donned the simple robes of a seventh-year student.
He chose to return.
To complete his final year—as a student.
It puzzled everyone.
Yet, upon reflection… it felt exactly right.
A true seeker of knowledge, untouched by fame or power.
From then on, Hogwarts gained a unique sight.
In Potions class, as Professor Slughorn nervously explained complex brews, the "god" sitting in the corner might casually point out a more efficient step—leaving the professor overjoyed.
In the library, when Hermione and Daphne puzzled over ancient runes, the "living legend" would stroll by, offer a key insight, and recommend an ancient text not even found in the Restricted Section.
On the Quidditch pitch, after Gryffindor's victory, Harry Potter would fly past the Astronomy Tower and solemnly salute the figure sitting quietly atop it, gazing at the stars.
He was a student.
And yet… everyone's teacher.
He was within the school.
And yet… beyond the world.
Wherever he went, he received the most sincere greetings and reverent gazes.
He became something unprecedented in Hogwarts history—
A true…
"Legendary Student."
The new school year at Hogwarts was full of vitality.
And among the many changes, the most eye-catching was the Defense Against the Dark Arts class—once considered cursed—now welcoming its most prestigious and unquestionably powerful professor ever:
Kingsley Shacklebolt.
The newly appointed Minister for Magic, known for his integrity and ability, shocked everyone by personally taking on the role.
"Nothing is more important," he said, "than teaching the next generation how to recognize, resist, and ultimately defeat darkness."
On the first lesson of the term…
The seventh-years entered a packed classroom, filled even along the corridors with students auditing the class.
Because everyone knew—
Not only was the "Minister Professor" present…
But also…
The "living legend."
Lin Sen sat quietly in the back by the window, reading an ancient tome older than Hogwarts itself.
As if nothing around him mattered.
Kingsley stepped to the podium. His sharp gaze swept the room, briefly pausing—almost imperceptibly—on Lin Sen, a flicker of deep reverence in his eyes.
"Good afternoon, students."
He taught brilliantly—from the principles of the Shield Charm to the emotional core of the Patronus; from identifying dark creatures' weaknesses to maintaining composure in battle.
Every word carried the weight of real experience.
Even Sirius Black and Remus Lupin, serving as practical instructors, nodded in approval.
But after finishing…
Kingsley stopped.
Closed his book.
Turned.
And faced the back of the classroom.
Then—before everyone's stunned eyes—
The Minister for Magic bowed deeply to a student.
"Lord Lin Sen."
His voice was humble, sincere.
"What I have taught are merely the small techniques mortals have developed in the dark to protect themselves. My knowledge is limited."
He looked up, eyes burning with devotion.
"But we have all witnessed the miracle you performed—the Eternal Bastion."
"So…"
His voice trembled slightly.
"Would you be willing… to show us…"
"What true defensive magic is?"
Silence fell.
Absolute.
All eyes locked onto the figure in the back.
At the center of all attention—
Lin Sen finally closed his book.
He looked up.
Those calm eyes, like a universe of stars, swept across the room.
He did not answer.
He simply stood.
And walked to the podium.
Each step seemed to echo through history.
Then, facing the crowd of eager faces, he spoke:
"What you have learned… is technique."
"What I will teach you… is the Way."
He raised his right hand.
"Your defense is passive—blocking. Like this."
His gaze fell on Sirius Black.
"Mr. Black. Use your strongest attack."
"I—I?" Sirius stammered, panicked. "I can't possibly—"
"This is a lesson."
After a struggle, Sirius raised his wand, gathering all his power.
"Stupefy!"
A massive red beam shot toward Lin Sen—strong enough to fell a dragon.
