An Impenetrable Door

It was another familiar darkness.

Countless Winky 'doors' in the darkness seemed to beckon to him.

The door he was most familiar with, the one he entered through for the first time, slowly approached him.

Harry opened his emerald green eyes, and a familiar yet strange room appeared before him.

This is his bedroom at the Black House. If you look at the bedroom layout upside down, it's not much different from when he left.

He turned the snake-head-shaped bedroom doorknob and opened the door.

Cold beams of light shone on Harry, and combined with his silver, reflective wizard robes, he now had the appearance of a ghost.

And this dark and terrifying room is his haunted house.

Harry understood that the Mirror World was a reflection of the real world.

Therefore, in the real Black Family Manor, it was also illuminated by candles that emitted a cold, desolate light.

After he left the Black House, even the rooms on the third floor, far from Regulus's room, were bathed in the same cold, desolate light as yesterday's birthday.

Sirius seems to have become accustomed to this lighting, for Regulus's sake.

Looking at the snake-shaped chandelier and the cool-toned candles on the candelabra on the table next to it, Harry couldn't help but think this.

Harry began to descend the dark staircase, and a row of wrinkled heads gathered on the wall panel next to him felt very familiar to Harry.

He was already used to the Dark Wizard elements in the Black House.

Even the large umbrella frame made from a Troll's severed leg was fascinating to Harry.

However, the appearance of the Troll umbrella also meant that he had arrived at the first-floor Entrance Hall.

He was not far from his destination for the day, the Boiler Room —which was also Kreacher's bedroom.

Narrow stone steps; rough stone walls; a dark room; a dark ceiling with heavy iron pots and pans hanging from it.

"It truly lives up to its reputation as the Grim Old Place (Grimmauld Place in short)," Harry remarked three minutes later, already standing in front of the boiler room.

However, as Harry got closer to his destination, the sticky, slippery, and cold magic became more and more apparent.

A series of wailing and sobbing sounds came from under the door.

Even though there was a door between them, Harry experienced a series of hallucinations as he heard the sounds.

It was a neat nest made of tangled, messy strips of cloth.

He saw the thing that made the sound!

The shape of that thing was that of a naked child, curled up in a nest, with rough, red skin that looked like it had been peeled off.

Harry swallowed hard. Although the thing was small, weak, and injured, he didn't want to get close to it.

However, he still moved over little by little, his hand slowly reaching for the doorknob of the Boiler Room, ready to slip away at any moment.

But as he turned the doorknob, ready to push it open, he suddenly realized he didn't have the courage to do it, like a coward.

"Perhaps reciting a prayer outside the door would also be helpful."

Such thoughts kept churning in his mind.

When he came to his senses, he had already let go of the doorknob, put his hands together, and knelt down in front of the Boiler Room door.

"Creator of Myriad Stars, master of the Opposite World, one who has broken free from fate and wields divine power! Those Fate-Similar Person yours call your name in your kingdom—" Unbeknownst to Harry, two identical yet slightly distinct voices rang out from his mouth.

Both of them began to pray at the same time.

As the prayer progressed, he felt a grand, vast consciousness envelop him, as comfortable and serene as being in the amniotic fluid in the womb.

The hallucinations became more and more obvious. The little monster, who had been sobbing helplessly in the cloth nest, suddenly jumped up and let out a series of eerie and terrifying roars at him behind the door.

But the door was like an insurmountable chasm, blocking the prayer behind it, "The remaining traces and memories will appear and be reforged under your Third Vision of exploring destiny!" like a bullet stuck in a rut, blocked by this thin door.

Harry then realized that the prayer might only work if he entered the room or even touched the little monster.

As the prayer ended, that sacred consciousness began to detach from his body.

A strange feeling, like that of a bride being abandoned by her husband, inexplicably welled up in her heart.

Taking a deep breath, Harry gripped the doorknob again—

"How could this be!" Harry realized he couldn't open it.

"Alohomora!" Harry chanted, pointing his wand at what appeared to be the lock.

But the door remains the same.

"Open Portal!" This crude spell, capable of smashing locks but sometimes leaving a smoking hole in the keyhole, was uttered by Harry.

The door remained completely still.

"Open Sesame!" Harry uttered the more violent "Open Sesame" spell, which ripped the door off the hinges and chopped it into pieces.

But this door, as if subjected to multiple counter-spells, remained completely unchanged.

"Confringo! Reducto! Diffindo! Avada Kedavra!" Harry gasped for breath, staring at the familiar yet strange door.

It wasn't as dirty as it looked when I first saw it.

But it seems that while removing the dirt, it also underwent a complete re-creation.

The entire door was practically Fianto Duri.

Apart from the door-opening spell, even the most destructive spells he haphazardly used at the end had no effect on it.

Even the Killing Curse, which can kill everything, has no effect on it.

"I've got it!" Harry seemed to have thought of something.

He pulled a small knife from his robe.

This is a multi-purpose knife, one of his birthday gifts.

Because in addition to being used as a knife, it also functions as an ear pick and nail clippers.

So Harry often carries it with him.

Furthermore, while at the Weasley family, Fred and the others taught him how to open doors using Muggle methods.

So Harry inserted the knife through the crack between the door and the wall, slid it from top to bottom, then pulled it out and bumped it with his shoulder.

But—the door was still tightly shut, just like before.

Not only that, when Harry looked down, he found that the blade had melted.

Harry slumped to the ground, staring at the door that didn't look very sturdy.

The sound of the little monster sobbing behind the door seemed to be mocking him.

"No, there must be other ways!" Harry encouraged himself again.

The Mirror World is a reflection of the real world.

The room he couldn't open was Kreacher's bedroom.

He can't do it, but that doesn't mean Kreacher can't.

Maybe Sirius could do it too.

Perhaps this is Sirius recently cast in the Boiler Room, which Sirius uses as a storage room for valuable items?

If all else fails, he can write to Ryan.

With a last glimmer of hope, Harry vanished from the spot through the smooth mirror of an iron basin.
