Chapter 539: 539. Two Lines of Light and Zero Witnesses

William accepted the scolding with the practiced deference of a student who had heard it all before, a meek expression on his face, and a silent, internal promise to do better that both he and Grock knew was hollow.

Promises made in the heat of a lecture rarely survived the reality of exhaustion.

To prove a point, William gripped the hilt of Aetherion. "It’s not neglected, Grock... Watch."

He channeled a precise stream of mana into the weapon’s core. The sword responded with a low, harmonic hum that vibrated through his bones.

He initiated the first mode shift: the blade split with a metallic shriek, rearranging its molecular structure from a single-edged shortsword to a deadly double-edged one.

Then, with a surge of power that made his veins bulge, he commanded the transformation to the Greatsword mode.

The weapon elongated, the weight redistributing itself with a grinding sound of shifting metal that echoed off the courtyard walls. The mana flowed through the blade like molten silver, visible even in the fading daylight.

"See?" William said, his breath coming slightly faster from the exertion. "Fluid... and even stable."

On the far side of the yard, the mundane rhythm of academy life continued. Ellie appeared on the cross path, a basket of laundry balanced precariously on one hip.

She moved with that same careful, measured gait she had adopted since the morning, too controlled, too deliberate. She was a hundred paces away, a distant figure against the stone buildings, and she did not so much as glance in their direction.

She kept her eyes fixed on the path ahead, her shoulders squared as if bracing against an invisible wind.

Then, it happened.

Aetherion shivered in William’s grip.

It wasn’t a mechanical malfunction. It wasn’t the recoil of the mana shift.

It was a small, sharp tremor—almost nothing, the kind of microscopic vibration a tuning fork produces when someone strikes a note just outside the range of hearing.

The vibration was so sudden and so unnatural that William nearly lost his grip on the Greatsword’s form; the blade wavered between states, the metal groaning as it struggled to maintain its shape.

William froze. He held the sword perfectly still, his knuckles white against the leather grip, watching with bated breath as the tremor gradually faded.

He watched until Ellie disappeared through the heavy oak doors of the dormitory, taking the source of the disturbance with her.

The silence that followed was deafening.

"It did that," William said, his voice barely above a whisper.

His heart was hammering against his ribs. "The blade... it reacted to her."

Grock stopped mid motion. He set down his polishing cloth with deliberate slowness, his bushy eyebrows knitting together.

The jovial dwarf who had been boasting about honey cake was gone, replaced by something older, harder, and infinitely more dangerous.

"That blade has never trembled without a reason," Grock said, his voice dropping into a gravelly register. "I know every thread of mana I wove into its core."

"I know its temperament better than I know my own kin."

"Aetherion doesn’t flinch for nothing... It doesn’t react to ghosts or coincidences." He stepped closer, his eyes boring into William’s. "What exactly did you feel?"

William couldn’t answer. His mind was racing, replaying the sensation the way the sword hadn’t just vibrated but seemed to cringe, as if something in the air had suddenly become hostile.

Grock followed the unspoken line of William’s gaze toward the empty dormitory doorway.

The dwarf’s expression darkened. He lowered his voice until it was nothing more than a rough murmur that seemed to come from somewhere deep underground.

"That girl," Grock began, his eyes narrowing. "Her magic... it’s too clean, William... almost too perfect."

"An ordinary elf’s magic has texture; it has a scent."

"Even the purest mana smells of something: ozone, pine, rain, summer heat..."

"But her magic? It doesn’t smell like anything... It’s a void. A perfect, terrifying emptiness."

William felt a chill that had nothing to do with the evening air. "What do you mean?"

Grock’s jaw tightened. "I’ve caught a scent like that exactly once before."

"A long time ago, in a place where the sky burned red and the screams never stopped... A place I’d rather not remember."

William’s blood ran cold. "Where, Grock?"

"Doesn’t matter." Grock’s face closed like a shutter, the conversation ending as abruptly as a guillotine blade falling.

The old soldier was retreating behind his walls. He picked up the basket of honey cake with unnecessary ceremony and thrust it toward William.

"Eat the cake. Now."

His eyes met William’s, stern and unyielding. "Bad thoughts are easier to fight on a full stomach."

"And you’re going to need your strength."

William took a piece of the cake. The honey was rich, complex, and layered exactly as Grock had promised; the sweetness hit the tongue first, followed by a deep, floral undertone that lingered like a memory.

"It’s incredible, Grock... Truly."

The old dwarf visibly puffed out his chest, a rare moment of unguarded pride crossing his scarred features. "Of course it is."

"My wife knows the alchemy of sugar better than most court wizards know their own spells." He immediately cleared his throat, attempting to reclaim his gruff demeanor. "Now, enough pleasantries."

"This edge, look at it again, William... If you don’t maintain it properly, the mana will start eating the steel from the inside out."

Grock returned to his relentless scolding, but William found himself listening only halfheartedly.

His mind was anchored to Grock’s earlier words: ’A place I’d rather not remember.’

William knew Grock’s lineage. The dwarf was the third generation of his family to serve the Astraea Combat Academy.

He wasn’t just a craftsman; he was a living archive. A man who carried the scars of three generations of warfare possessed stories that were older than most of the stone buildings surrounding them.

If Grock was refusing to speak, it wasn’t out of secrecy; it was out of genuine, bone-deep trauma.

A strange unease settled in William’s gut. He glanced down at Aetherion, which lay across the stone bench.

The blade had been polished to a mirror finish, reflecting the bruised purples and oranges of the twilight sky. But as his eyes traced the edge, something caught his peripheral vision.

In the reflection of the steel, hanging in the empty air behind his own shoulder, he saw two thin, vertical lines of pale, ghostly light.

They were faint, almost ethereal, like threads of silk suspended in water.

William’s heart skipped a beat. His hand instinctively flew to the hilt of the sword, but when he spun around, the courtyard was empty.

Only the long shadows of the evening stretched across the stones. The wind rustled through the nearby trees, but there was nothing there.

No intruder, no magical residue, and no sign of life.

When he turned back to the blade, the reflection was normal just the sky, the bench, and his own startled expression.

’Was I seeing things?’ he wondered, a cold sweat prickling at his hairline. ’Or was the sword showing me something that wasn’t there?’

He made a silent decision: he would not mention this to anyone. Not to Grock, not to Lia, and certainly not to Ellie.

He was already beginning to assemble a dangerous collection of unspoken truths, and he loathed what that said about the trajectory of his life. He was becoming a man who carried secrets like weapons, and weapons tended to draw blood.

The night before the festival arrived with an oppressive stillness. William lay in his narrow bed, staring up at the dark ceiling of his dormitory.

He tried to force his breathing into a rhythm and tried to summon the exhaustion that would drag him into unconsciousness, but sleep remained elusive.

Every time he closed his eyes, the darkness behind his eyelids became a canvas for his anxieties. He saw the thin lines of pale light dancing in the reflection of Aetherion.

He saw Ellie’s pale, unsteady hand pressed against her lower back as she tried to steady herself. He saw Clara’s face, the raw vulnerability she had shown when she admitted she needed time.

The images blurred together into a single, suffocating weight.

After midnight, when the academy had fallen into that deep, hollow silence that only exists in the dead of night, the system chimed in his ear.

The sound was sharp, clinical, and utterly devoid of emotion.

[Moderate Alert: Anomalous energy within a potential bond has increased.]

William’s eyes snapped open. He remained motionless, listening to the steady pulse of his own blood in his ears.

[Name: Ellie Von Synthia.]

[Anomaly Level: 38%.]

[Source: Unidentified. Energy structure does not match any recorded racial data.

[Recommendation: Monitor regularly. Avoid forced intervention without additional information.

William sat bolt upright in bed, the sheets pooling around his waist. His breath came quick and shallow. The blue light of the system interface cast eerie shadows across his room.

He stared at the words, reading the last line three times, each pass making the implications more terrifying than the last.

’Does not match any recorded racial data.’

The implications tore through his mind like a blade. He thought of Grock’s warning about the ’clean’ magic, the scentless void.

He thought of the way Aetherion had shivered when she passed.

"Racial data," William whispered aloud, his voice cracking in the empty room. "You’re telling me she isn’t an elf?"

His mind raced through every classification he knew: human, elf, dwarf, beastkin, demon, and spirit. None of them fit.

If she wasn’t what she appeared to be, then what was she?

And more importantly, what kind of catastrophe was walking the halls of the academy in the skin of a girl who could barely carry a basket of laundry?
