By the time Sargeras returned to Hogwarts, it was already the afternoon of the following day.

The purpose of this trip had been fulfilled perfectly. Sitting comfortably in the chair behind his office desk, he quietly gazed at the delicate hourglass resting in his hand, a pure, satisfied smile slowly spreading across his face.

The Time Turner — the Ministry of Magic's top-secret artifact, strictly restricted to authorized users only. This was an extremely rare and peculiar magical device, and its function boiled down to a single, astonishing purpose — time travel!

He could still remember that, in his previous life, the famous theoretical physicist Stephen Hawking had once proposed the Chronology Protection Conjecture. Hawking believed that quantum effects would ultimately prevent large-scale time travel, thereby avoiding all those troublesome paradoxes that plagued science fiction.

More than twenty years had passed since then, yet fragments of those theories still lingered faintly in his mind. After all, there was a time when he had placed unwavering faith in the power of science.

But ever since crossing over into this world, that faith has shifted… now, he believed in magic.

The longing to return to the past — surely, that was a desire every person had harbored at some point in their life.

Sargeras was no exception. Or rather, had been no exception — those were the kinds of thoughts he'd entertained before his transmigration. Now, his research into the Time Turner wasn't driven by any foolish yearning to rewrite regrets. His only goal… was to deepen his understanding of magic itself.

After carefully examining the hourglass from top to bottom, his brows furrowed ever so slightly, entirely beyond his control.

"Let me think…" Sargeras murmured to himself, sinking into deep thought. "There are a few things I need to be cautious about. The Grandfather Paradox… The Butterfly Effect… The first could lead to logical contradictions capable of collapsing the entire timeline. As for the second… even the tiniest change could ripple outward, snowballing into a future that becomes completely unrecognizable, beyond anything we could predict or recognize."

The true nature of a collapsed timeline was the breakdown of reality's logical continuity. And the consequences of that… far exceeded anything human comprehension or control could ever hope to contain. It wasn't merely the destruction of the physical world. It was a fundamental erasure of existence itself… a denial of meaning, of causality… even of free will.

Sargeras tried to wrap his head around the concept of time travel using the knowledge he possessed — but in the end, he gave up almost immediately. After all, if the reason something happened in the past was actually the result of his future self interfering with that very past… wouldn't that be cause and effect turned completely upside down? An endless, maddening loop with no beginning or end?

"Enough thinking for now." He waved his hand dismissively, shooing the raven, Noctis, out of the room. He had made up his mind — the first thing he needed to do was fix the Time Turner in his hand, then… he would try it for himself.

That was the only way.

Only then could he truly and thoroughly comprehend the mechanisms behind the workings of time magic.

————————————————————

The core of the Time Turner was woven together from two things: Time Dust and Threads of Fate. These two elements represented, respectively, the embodiment of the laws that governed the movement of the celestial bodies… and the tangible manifestation of cause and effect.

And as for the Time Turner in his hand… the problem clearly lay with the Time Dust.

Long-term use would inevitably consume a portion of the Time Dust, and that subtle yet relentless depletion disrupted the delicate balance between the two forces, ultimately leading to the device's malfunction.

To repair it, he would have to recalibrate the resonance frequency between these two energies and restore their equilibrium.

The problem was… Sargeras currently didn't have any spare materials on hand to replenish the missing components for the repair.

"If I can't restore the original balance for now… could I perhaps achieve… a new one?" The moment the thought crossed his mind, inspiration struck like lightning. He quickly decided to try a different approach — he would extract a portion of the Threads of Fate and rebuild the equilibrium from scratch.

"I really am a genius," Sargeras couldn't help but admire himself, his voice brimming with excitement at his own brilliance.

With a clear direction in mind, the repair process progressed rapidly. After three full days and two sleepless nights of tireless effort, the Time Turner finally regained its former vitality — it was as good as new, gleaming faintly with magical energy once more.

"A piece of cake!" He examined the hourglass in his hand with great satisfaction, unable to hide the excitement bubbling in his chest.

"Let's start with a one-minute test." Stepping out into the corridor, Sargeras carefully set the dial and flipped the hourglass over.

In an instant, his entire body froze in place, as though time itself had pressed pause — yet, his mind remained astonishingly clear and active.

Through the tall windows, he saw the birds outside fly backward across the sky… the setting sun reversed itself, gradually transforming back into a blazing midday sun… his raven, Noctis, fluttered in and out of the window repeatedly… in the distance, the autumn leaves shifted from golden yellow back to fresh, vibrant green… the snowflakes drifting through the air gathered from the ground and flew back into the sky… even the furnishings in his office rearranged themselves, changing position before his eyes… unfamiliar faces came and went, disappearing and returning as if reality itself were stuck in a strange loop.

And in the final moments of this strange, impossible scene… even the walls and ceiling surrounding him faded away completely… vanishing into nothingness

By the time he regained control of his body, he found himself already standing on a massive boulder in the middle of the wilderness.

Sargeras turned his head slowly, scanning his surroundings with sharp, cautious eyes — yet for the first time in a very long while, there was a flicker of confusion in his expression.

Where the hell… had this thing taken him?

Hogwarts… was gone?

The bewilderment on his face was quickly replaced by an undeniable trace of horror.

So… this was at least a thousand years in the past!

At that realization, Sargeras finally quieted down… completely.

He picked up the hourglass in his hand, examining it over and over again, but no matter how closely he looked, he couldn't spot anything wrong with it. The fine sands within still defied gravity, flowing steadily from bottom to top… everything appeared to be working as it should. So where… exactly… had the problem occurred?

It seemed… the Time Turner had sent him to a timeline where he didn't originally exist at all.

Sargeras had no idea how that was even possible. After all, Time Magic was far too complex, and he had only just started dabbling in it not long ago.

Maybe… maybe once the sand inside the Time Turner completely finished flowing backwards, he would be able to return to his original timeline?

"That will probably take a few days…" Sargeras estimated in his mind, watching the speed at which the golden sands drifted through the hourglass.

But thankfully, he still had his wand and all his other essentials on him. He quickly checked over his belongings, and to his surprise, even managed to fish a small half-full bottle of Felix Felicis out of his pocket.

Thank you, Veiliss! Regardless of whether this so-called luck potion for traveling through time actually worked or not, he didn't hesitate — tilting the bottle, he carefully let three drops fall onto his tongue.

"At least a thousand years… hopefully, it's still within its shelf life," Sargeras sighed helplessly. But almost as soon as the words left his mouth, he caught himself, a faint trace of amusement flickering across his face.

"Wait… that doesn't make any sense. Technically, this thing wasn't even manufactured yet. Its production date is still over a thousand years in the future. So how could it possibly be expired?"

He forced himself to stay optimistic. After all, could things really get any worse than this?

Taking a deep breath, Sargeras once again surveyed his surroundings, stubbornly searching for even the faintest trace of something that matched his memory of Hogwarts. But in the end… he gave up once more.

Time had left its marks on this land far too deeply. If he weren't witnessing it with his own eyes, he never would have believed that this barren, desolate wilderness was actually what the site of Hogwarts looked like… over a thousand years in the past.

"What are you looking for?"

A cold, crystalline female voice suddenly came from behind him. Sargeras's entire body tensed in an instant, his back straightening like a taut bowstring.

The voice was so close… it felt as though someone was whispering right beside his ear. Yet, to his utter disbelief, he hadn't noticed a single soul approaching — it was simply impossible.

"Shadowless step!"

Without a second thought, Sargeras instinctively triggered his teleportation spell. Three consecutive space-jumps cracked through the air with sharp, ear-piercing sonic booms.

His figure blurred, leaving behind three faint afterimages as he reappeared ten meters away, standing atop a large stone.

By the time he stabilized himself, his wand was already raised, aimed squarely at the source of the voice. Crimson light gathered at the wand's tip, and the surrounding air visibly warped under the searing heat of the brewing spell.

It was only now that he finally saw the figure clearly.

A tall woman stood there, cloaked in flowing silver-blue robes. Her eyes were calm, detached, with an air of refined grace about her, as though she couldn't care less about the wand pointed straight at her.

"What was that you just drank?" the woman asked again, her tone peculiar — flat and emotionless, with barely a ripple of fluctuation.

Sargeras's face darkened considerably.

Because at that moment, he could feel countless invisible threads of magic creeping toward him like an enormous spiderweb, quietly spreading in all directions. Those threads were as fine as gossamer, yet they carried a terrifying, penetrative force, prying relentlessly at the mental defenses surrounding his mind.

In the brief exchange of only a few sentences, the woman had already launched more than a dozen covert attempts to invade his consciousness. If not for his formidable Occlumency barriers… his mind would have been thoroughly rummaged through by now.

"Impressive Legilimency…" Sargeras's voice was ice-cold, his expression hard as stone. "But unless you want to end up as a corpse, I suggest you stop trying to break through my Occlumency… immediately."
