The Great Hall of Hogwarts was nothing short of breathtaking.

The enchanted ceiling mirrored a starry sky, while floating chandeliers bathed the impeccably aligned tables in a soft, warm glow.

The ancient stone walls, adorned with the vibrant banners of Gryffindor, Slytherin, Hufflepuff, and Ravenclaw, exuded a timeless sense of historical majesty.

It was the inaugural night of a new school year, and anticipation hung in the air as the Sorting Hat had just assigned a young witch to Slytherin when Albus Dumbledore rose, his gentle smile lighting up his face.

His affectionate gaze swept over the students as he prepared to speak.

"Welcome to another year at Hogwarts!"

His warm voice echoed through the hall.

"Before we begin our feast, I'd like to share a few words: Nitwit! Blubber! Oddment! Tweak! Thank you."

The hall erupted into laughter and applause, as was customary, while everyone eagerly awaited the feast.

However, before the dishes could appear, a thunderous sound reverberated through the castle, reaching even the farthest corners of the magical world.

Suddenly, two immense curtains of light appeared in the sky.

One was as white as snow, radiating a blinding purity; the other was black as an abyss, absorbing all light around it.

The contrast was terrifying, and a deadly silence fell over the hall.

Dumbledore reacted instantly, casting a protective spell for the students.

But, to his surprise, the spell did not respond.

His usually calm face contorted in shock.

Albus Dumbledore, the "White Devil", felt his magic effortlessly blocked by an invisible force.

It wasn't just him who was astonished; professors and older students also felt the same paralyzing force.

For the first time, they experienced what it was like to be defenseless like Muggles.

"Stay calm. Everything is under control!"

Dumbledore's voice was firm, trying to contain the rising panic.

Even in the face of the situation, he remained composed.

But before he could continue, words began to appear on the curtains of light.

[This is the Dual Comparison Room, where the protagonist of this world will be compared to the protagonist of a parallel world.]

[During the broadcast, questions will be asked. Correct answers will be rewarded with various forms of magic, abilities, resurrection, longevity, magical power, and more.]

[Remember: while the broadcast is active, everyone's magic will be sealed, and no attacks will be allowed.]

[A chat room will soon be formed. Only relevant characters will be invited to participate.]

The hall plunged into silence once more as everyone read the projected messages.

"Fred, look at this! Do you think it's some kind of alchemical item?"

George whispered, his eyes sparkling with curiosity.

"Don't be silly, George! This is clearly alien technology! I bet an invasion is about to happen!"

Fred replied, and the Weasley twins burst into laughter, infecting the younger students with their cheer.

"Harry, what do you think this curtain of light is?"

Ron was still trying to process what was happening.

"How would I know? I'm not even really a wizard yet. I don't know much about magic."

Harry shook his head, as confused as his friend.

"Besides, didn't you see that even Dumbledore seems surprised? If he doesn't know, how would I, just an ordinary kid, know?"

Hermione, already impatient with the two's ignorance, huffed and rolled her eyes.

"It's obvious these curtains are here to show us something. Pay attention to the messages!"

Meanwhile, Minerva McGonagall quickly approached Dumbledore.

"Albus, what is happening? What kind of magic is this?"

Snape also silently approached, his somber expression reflecting the same question.

Dumbledore didn't answer.

He was focused on a smaller curtain of light, separate from the two main ones, apparently the "chat room" mentioned.

Then, a familiar voice echoed.

Gellert Grindelwald: "What kind of magic is this? Is there magic I don't know?"

The impact was immediate.

A collective chill ran through the hall, and the magical world trembled.

For the older wizards, memories of the chaos caused by Grindelwald resurfaced.

His charisma, devastating power, and loyal followers were grim reminders of the days before Voldemort's rise.

Dumbledore's heart raced at the sight of his old friend's name.

He barely managed to maintain his composure as he read, but a whirlwind of emotions consumed him.

Fred Weasley: "Hey, George, looks like we can chat too."

George Weasley: "Seems like we're important, haha!"

Molly Weasley: "You two, be quiet now, or you'll be grounded forever!"

Lucius Malfoy: "Hmph, of course, the Weasleys... A disgrace to purebloods."

Arthur Weasley: "Careful what you say, Lucius. You wouldn't want your house searched, would you?"

Lucius Malfoy: "Arthur Weasley!!"

The chat room quickly turned into a heated debate, easing the tension.

But then, a specific message caught the attention of many, especially one person.

Snape's eyes were fixed on the screen, unable to believe what he was seeing.

The message mentioned his greatest love and regret.

Lily Potter: "Excuse me, does anyone know how my son is? His name is Harry Potter."
