At Hogwarts, the story begins with deconstructing Avada Kedavra.

Inside the hidden spaces of the Ravenclaw Tower.

The dome directly reflects the starry sky, with a starry chessboard suspended in mid-air, radiating that eternal, deep blue that belongs to Rowena Ravenclaw.

Lucien sat in a high-backed chair, his robe half-undone on his left shoulder.

The air was thick with the pungent smell of white perfume. The gruesome gash caused by the stray bullet from the accidental collision of the Shattering Bone and the Explosion Curse, a low-level spell, was slowly healing.

Outside the tower, the wound could not be stopped even by Snape's potions, but here it could be easily treated with white cinnabar.

He gently waved his wand, and the suspended starry chessboard rearranged. Stardust gathered, outlining several figures.

On one side is the red lion representing Harry, Ron, and Gryffindor; on the other side is the green viper representing Malfoy and Slytherin.

At the edge of these two beams of light, a golden star that should have been at the core connection point, Hermione Granger, was now dim and lonely, drifting on the edge of the galaxy.

Lucian reached out and through the illusory stardust, fiddling with the chess piece that represented Hermione.

That proud little witch, whose intelligence made her seem out of place, was experiencing the darkest moment of her life. She tried to stop the conflict but was hated by both sides; she wanted to prove herself right but discovered that even the savior Harry had chosen blind loyalty over the rules.

"What an interesting experiment."

Lucian gazed at the chessboard, the swirling stars in his eyes slowly shifting.

He reviewed the achievements of the past few days. He had instigated a full-scale war between the two houses, forced Snape and Professor McGonagall to intervene, and ultimately shattered the beliefs of the Muggle-born witch.

To outsiders, this was a campus brawl he instigated to satisfy his perverse sense of humor.

In reality, this is not the case. Behind this seemingly chaotic entertainment lies his purpose: to measure the changes in the behavioral logic of the world's will.

Lucian raised his hand and projected the Halloween troll incident from months ago onto the left side of the chessboard.

That night, when he tried to sever the bond between the savior and the little witch, the world's will reacted violently and directly. Golden threads fell from the void, brutally invading the brain and forcibly distorting memories and emotions, like a clumsy screenwriter forcibly forcing actors back into their roles.

Because that's the foundation. The troll incident was an absolute necessity for the formation of the magical trio.

But this time is different.

Lucian looked at the corridor brawl that had just ended on the right side of the chessboard.

Its nature was several times worse than the Troll Incident. The conflict between Gryffindor and Slytherin escalated dramatically. Hermione Granger not only failed to integrate into the group, but was also completely excluded from the main cast due to her sense of superiority and the resulting isolation.

The plot has already taken a certain detour.

However, this time there was no golden thread falling from the sky, nor any forced brainwashing or dehumanizing manipulation. The world's will merely inflicted a physical wound on him through the spell's failure by two idiots.

This reaction is too mild.

It could even be described as a compromise.

Why did this change occur?

Lucian stood up, his robes tracing an arc in the starlight. He walked to the center of the chamber, feeling the magical pulse beneath his feet—the heartbeat of Hogwarts magic.

The ancient star map on the dome was turning silently, and the air was filled with the lingering fragrance of magic left over from hundreds of years ago.

He had reached a preliminary conclusion in his mind.

First of all, this brawl does not involve the main plot of defeating the Dark Lord; it is a subplot of school life, involving only the confrontation between the two houses. Moreover, Malfoy and Harry successfully became enemies, so the stress response mechanism of the Great Calamity was not fully triggered.

Secondly, and most importantly.

During the Troll Incident, he was merely a gifted outcast. But afterwards, he solved the statue's trials, inherited the hidden space, and gained Ravenclaw's legacy.

He was no longer an outsider who could be erased at any time. He bore the mark of the founder of Hogwarts, which gave him greater weight and a certain degree of immunity in this world, or rather, in this magical sanctuary.

The world's will still reject him, but it can no longer distort the reality around him as easily as crushing an ant.

"As the weight has increased, the way of rejection has also changed."

Lucian smiled with satisfaction and removed all the bandages.

This is extremely valuable intelligence. It means he can begin to intervene more deeply without constantly worrying about being brainwashed by illogical causal weapons.

As long as Harry Potter isn't killed directly, and Voldemort's main soul isn't destroyed directly, the world will have to swallow its anger and endure most of the plot deviations because of his special status.

But this is only a preliminary inference.

To confirm the upper limit of his tolerance, he needed a more suitable control group—an event that both belonged to the main storyline of Harry Potter's growth and offered room for maneuver.

He pictured a tall, rugged figure.

Rupert Hagrid.

Lucian's gaze fell toward the edge of the forbidden forest, toward the hunting lodge.

Judging by the timeline, that famous half-giant who was easily fooled and emptied his pockets should have already received that dragon egg, which was destined to cause a lot of trouble, from some stuttering man wearing a turban.

In the established script, the birth of the dragon is a crucial turning point. It makes Harry realize that as long as he shouts for love and justice, even if he violates school rules, there will be no real punishment. It binds the trio together during their nighttime adventure and ultimately leads to the critical moment when they must enter the Forbidden Forest to be punished and confront Voldemort.

Even more fatally, after this incident, they were completely captivated by Gryffindor's courage and developed a path dependency, forever remaining reckless.

All of these elements combined form the story of the savior's battle against the dark king.

What if he knocks a link off this chain?

What if Hermione, disheartened, refuses to participate in this obviously rule-breaking and foolish thing anymore?

Without the little witch's overall planning, could the savior and his red-haired friend really successfully send a fire dragon up the tower?

What if the fire dragon wasn't sent away on time and instead caused even bigger trouble?

How will the Great Calamity repair this broken storyline? Will it unleash the golden thread of brainwashing once more, or trigger an even more uncontrollable butterfly effect?

Lucian waved his wand, and the light and shadow on the Starry Chessboard vanished.

He summoned a book, the cover of which boldly proclaimed: "The British Code of Smuggling Prohibited Magical Creatures and Penalties."

Now that the stage is set up and the actors are in their places.

So, it's time to drop an indelible ink stain into the savior's adventure diary.

"Hagrid, you'll thank me."

Lucian chuckled and closed the book.

"After all, who wouldn't prefer a stronger, healthier... and more deadly fire dragon?"

He left the statue space and walked to the tower window.

The forbidden forest outside the window swayed in the strong wind.

As the days passed, the discussions in the castle about the conflict that night gradually subsided.

But instead, there is a more direct confrontational sentiment.

Everything is building up, waiting for that upcoming Quidditch weekend.
