Harry Potter: A Certain Ancient Rune Professor of Hogwarts (TL)

At night, deep in the forbidden forest.

A large black dog ran desperately, his lungs wanted to burst out, the shadow and shape of the trees in the inky black forest became jagged claws, he crossed a forest stream and turned around to look behind him warily.

The terrifying three-headed dog did not pursue him.

He slumped on the ground and stretched his body. He looked at a sliver moon, the full moon had just passed, and he wondered how his old friend is doing now, whether he would draw his wand as soon as he saw him and give him a nasty blow.

Still, he considered using full moon day as a chance to abduct his old friend and tell him the truth about what happened.

But unfortunately, the shrieking shack which he remembered for being so lively before, had become extraordinarily deserted, with a thick layer of dust gathered with no sign of use.

‘Maybe I’m the only one who remembers that place.’

He thought that this might be the reason why the passage towards whomping Willow wasn’t blocked off.

But even if it’s blocked, it does not matter to him. He knew many secret passages, and the one-eyed witch on the third floor of the castle is his best bet, of course, it leads to the cellar of Honeydukes Sweetshop, which is full of customers.

Dementors constantly patrolling Hogsmeade day and night, so he glanced from afar and rushed away.

He didn’t dare to gamble, he would probably only get one chance, this isn’t school, it’s not about fighting with those young Death Eaters, this is war. He told himself to be patient.

Likewise, he wondered how long he could hold out though, there used to be people who would remind him and tell him not to be impulsive, but now he is all alone.

Just like some time ago when he had been unable to resist and sneaked to the edge of the Quidditch field just to get a look at the boy with the messy hair, like his dad, at the time he had a strong urge to rush out, and he was almost driven mad by that feeling.

He didn’t know if the information that he is Animagus had been revealed, his old friend had seen him transform too many times, just as he could recognize the vile rat at a glance, and his old friend could surely recognize him at a glance.

Maybe, at this moment, the Ministry of Magic Auror holding a picture of a black dog in their hand.

But they certainly could not recognize his current self. The black dog stood up, looked at his reflection in the stream, and let out a low whine that sounded like a satisfied laugh.

In the water there is a big, skinny, bony dog with a perfectly visible skeleton, black fur tangled together and bunched up stiffly. No different from a stray dog.

Perhaps he can go back to Diagon Alley and rummage through the rubbish cans or something … big black dog gulped, no, must be cautious.

The big dog made his way to the creek and took a few sips of water, his stomach twitched, and his eyes kept surveying the stream to see if there is a small fish passing by, a small shrimp would do. But he undoubtedly got disappointed.

‘Can’t turn into a human, I’ve shown up in Diagon Alley, I can’t appear anywhere else, especially near Hogwarts.’ He thought.

There was heavy rain that night, the chance was too good for him to stop from trying to enter the castle, the portrait wouldn’t care about him, he would be nothing more than some little wizard’s pet, or a playmate that guy Hagrid had got for his dog.

By the time a professor realized he is there, he’d be through with it.

But a buzzing at the castle gate made him flee, he didn’t know what it was, maybe an alarm of some kind?

He had seen quite a few of these gadgets when he was a kid.

It must be Dumbledore who managed to get it there, as he knew Nicolas Flamel.

Dumbledore …

The big dog’s eyes lit up, then quietly became dim again.

He must HATE me now! They believe I’m the traitor!

But I am the cause of James and Lily’s death, and I am indeed the culprit.

The big black dog’s mind kept racing around, and it’s hard to form a complete thought, so he started thinking about the three-headed dog he met today.

He had seen it at Hagrid’s hut from afar, when it was only as big as a coconut, and Hagrid was playing fetch with it, and even the hound beside it could easily mow it down.

But after only a week or so, the little thing that could have been slapped away by him grew to the size of a door. That was absolutely magic!

He heard Hagrid huffing as he said he shouldn’t have been so selfish, and he should have let it run free in the forbidden forest.

Damn! The three-headed dog now runs towards him. If he had known, he would never have lent the motorcycle to Hagrid.

After so many years, it probably got scrapped long ago.

Or maybe it had been set free? He had seen a broken car deep in the forbidden forest, which he thought had been abandoned, and was prepared to get into it and sleep on it – even if it’s broken, it’s still much better than the wet ground, and at least there’s a cushion.

As a result, that thing flashed its headlights on, shaking him nearly unconscious, and then that car came crashing towards him, making him flee once again in disarray …

Half an hour later, by accident, the big black dog found a mouse hole, haha, today is my lucky day.

With a full meal, he had the strength to hold out for at least two more days.

He lay down on the ground and began to think about the problem. He is unable to think thoughtfully in his big dog form, and he refused to be named and became a pet dog for food, so he simply tried to recall a familiar face.

I don’t know how long passed until he thought of the big ginger cat, a clever chap that he found he had come to like, even though he is a dog.

The cat could catch mice openly and honestly.

Through it, he knew quite a lot of information about the rat, foremost, that rat is right next to the boy, and that thought alone made him grumpy.

The big black dog began to count his ribs, which is his newfound way to remain calm. One, two, three … a total of thirteen pairs of ribs, the last one is the shortest and thinnest, the average person could not spot it, he thought smugly.

He finally calmed down.

For the time being, there is no need to worry … that rat is a coward, he knew it since he was in school, and every time there was a group fight, he would hide in the back and sneak attack.

Then there is that nasty guy, and his snake students, the danger is everywhere, but he is isolated.

The big black dog stood up, glanced in the direction of Hogwarts from afar, then turned around and left in the other direction.

He is going to make a trip to Muggle town, where there is little danger, and he can slip into a Muggle house to find something to eat.

Soft white bread, fresh and delicious vegetables, and, of course, meat.

The big black dog’s mouth drooled like crazy.

He ran slowly, which is the most energy-efficient way, and something he only recently discovered. Previously it was not like this, he always ran in the forefront.

It became dawn and the big black dog slipped quietly into the nearest house, a small house painted red, a colour he liked.

There is no TV in the room, which is even better, he doesn’t want to see any news about being called a dangerous fugitive, even though there probably won’t be one in muggle country.

The big black dog’s nose kept twitching as he turned and ran into the kitchen, where he saw a snow-white cat, too young to be smart from a glance, he thought.

Not bothering with the angry cat, he took a chunk of ribs from the kitchen, and on his way out, he patted the white cat on the head, leaving a dirty paw print.

Walking out of the small house, he left quietly with the meat in his mouth, and on the way, he saw two short, middle-aged men with probing eyes. As they discussed in low voices-

” Did you decide which one you’re going to start with?”

“Not sure yet, this town is too poor, how about a different place?”

“No, just pick a random house.”

Then they saw a large black dog slowly emerge from the shadows, it is thin and bony, showing its teeth, looking at them fiercely.

“Run!”

The big black dog watched them disappear, and his mood became cheerful as he let out a howl happily. Then the town filled with barking dogs, and the lights of a few homes turned on.

‘Damn, I’ve done something stupid again.’

He can’t stay here anymore. The big black dog went back into the grass, picked up the ribs, and left quickly.
