In the year 1340 of the Shire Reckoning, one year before the departure of the Lonely Mountain expedition, the Grey Wizard had yet to visit the Shire, the Dwarf King was still forging weapons in the Blue Mountains, and the dragon still slept deep within the mountain…

In that very year, a young wizard unexpectedly crossed into Middle-earth, carrying the Hogwarts Sign-in System.

Overnight, Hogwarts Castle rose from the ground, standing tall and majestic on the lands of Middle-earth; flying broomsticks streaked across the skies, becoming a unique sight in this world.

In the wild lands, the legend of a black-robed wizard began to spread silently.

He was a friend of the Elves, a bane to the Orcs, a nightmare to the Trolls, and the lifelong nemesis of the Dark Lord Sauron.

Years later, when the Dark Lord was defeated, the Elves sailed West, and the Age of Men began—Duir, who had signed in at all corners of Middle-earth, looked toward the fabled lands in the West.

In the shadow of the green lantern, Carl tapped Voldemort's diary with a hook stained with evil despair.

"Poor lonely ghost, you are mine, come out and play, how are we going to carry out this pleasant torture?"

On the day when the owl delivered the Hogwarts admission letter, Carl was excited, but also glad that he did not choose "Harry Potter" when he copied books to make money. He was just one step away from biting into the special melon of Avada. After Professor McGonagall arrived, Carl discovered his talent (external plug-in): "Detect Minerva McGonagall, Animagus Transformation... Match Nidalee, Vastaya Xayah Transformation..."

It is understandable that they can transform into a cat, but why did Professor Snape match Viego? "Forever lost my love! Defeat with a single glance!

Soar into the sky with the giant dragon of the Black Forest;

learn the fairy magic in the Fairy Garden;

meet the goddess of luck at the Fountain of Good Fortune with the brave;

combine the three holy relics into one in the face of the god of death;

in a world where wizards exist, are fairy tales the fantasy of genius or embellished history?

Through the mist of history, across the boundary between this world and the next.

Avalon, please show the truth of the world to the wanderers.

"My dream used to be to become a best-selling fairy tale writer in the Muggle and wizard worlds."

The reporter from the Daily Prophet raised the microphone, "What about now?"

"I have written my life into a fairy tale that I am most satisfied with... Look, whether it is Muggles or wizards, is there anyone who can refuse my story?"

He was at Hogwarts, and had just become a Half-Blood Prince.

In 1976, 16-year-old Severus Snape welcomed a new life.

That year, Voldemort had not yet split his soul into seven pieces.

That year, Nagini was still hiding in the forests of Albania.

That year, Pandora was still doing wonderful experiments at Hogwarts.

That year, Ms. Rosmerta was in her prime and very graceful.

That year, Snape decided to experience this wonderful world.

In 1991, Harry Potter, who was looking forward to campus life, stood on the platform of the Hogwarts Express, accompanied by his parents, godfather, Uncle Remus and a snow-white owl, and hugged and said goodbye to them one by one. The wind blew his bangs aside, revealing his smooth forehead above his green almond-shaped eyes. He just felt that he was the happiest little wizard in the world. The last person to say goodbye to him was his godfather, Sirius Black. "Harry, remember, have fun!" Black squatted down, his grey eyes sparkling, "If anything happens, you know, just look for Uncle Regulus—" This is a story about a game geek who plays "Assassin's Creed" and travels through time to the story of Regulus Black, a relative of Harry Potter. Regulus is responsible for hard work, and others are responsible for happiness! Protagonist: All..

If Dumbledore had not defeated Grindelwald.

If the war between wizards and Muggles really broke out.

If the finger witch that the faded one failed to meet was reborn in the body of an 11-year-old wizard girl.

My name is Hermione Granger, and I will rebuild the magic circle of this broken world.

What era is it now? Are you still using traditional magic wands?

Come try this round wand, which can release three spells at the same time, and its main feature is the surprise effect.

Let’s take a look at this one. This staff is 1.5 meters long and made of iron wood. Dragon breeders all say it’s good.

There is also a cool lightning wand, a two-handed wand with double the power, an easy-to-operate trigger wand, and a finger-sized 7.62...

As the only designated heir of the Ollivander family, Siren feels that he needs to give the backward wizarding world a little shock.

Edward traveled through time again and came to a mysterious world.

From then on, there was a stranger here who could travel between the two worlds regularly.

So, what will he bring to both worlds?
