The Essence Flow

Chapter 197: Owe Me One

The academy was a tomb of silence, save for the gentle, sighing breeze that nudged against the leaded glass windows. A sliver of moonlight, pale and cold, cut across the endless rows of bookshelves, illuminating dust motes dancing in the still air. In the heart of this vast, sleeping knowledge sat Professor Kaen, a solitary sentinel in the quiet dark.

It was the hour of the wolf—2 AM—when the world belongs to ghosts and secrets. As the self-appointed protector of the library’s lore, Kaen often kept these late vigils, a silent guardian against more than just overdue books.

“I’m sure this place will be a circus of panic by next week…” he murmured to the silent shelves, the words absorbed by the leather-bound volumes. He could already feel the impending chaos of midterms—the frantic energy of students trying to cram centuries of theory into a few sleepless nights. The thought brought a faint, wry smile to his lips.

It vanished in an instant.

His head tilted, a predator catching a scent on the wind. His gaze, usually veiled by academic detachment, sharpened and slid toward a large window overlooking the shadowed courtyards. His eyes narrowed to slits, reflecting the faint moonlight.

The breeze died. The very air grew taut.

“Looks like we have guests,” he whispered, the words no longer idle musing but a low, promising threat. Outside, where nothing should have been moving, a shadow had detached itself from the others. It was wrong. It was moving. And it was inside the wards.

A deeper blackness coalesced against the moonlit slate of the dormitory roof. Two figures, etched from shadow and silence, stood where no one should have been.

“Based on the report—the anomaly’s signature should be emanating from here,” the first shadow murmured, his voice a low-frequency hum that barely disturbed the night.

His partner’s gaze swept downward, towards the scarred earth near the forest’s edge—a grim reminder of a battle that had left its mark on both land and memory. “Yeah. The one who completely erased Subject #4.” A cold, professional respect tinged his words. “Let’s make this quick.”

With a whisper of polished metal, a blade appeared in his hand, its edge catching a sliver of moonlight like a sharp, hungry smile.

A nod from his partner. A second artifact was produced, not a weapon of immediate violence, but one of calculated isolation. It was a disc of dark, non-reflective metal, about the size of a plate, with a faint, pulsating violet glow at its core.

A thumb pressed a nearly invisible switch.

Thrum.

A wave of invisible force expanded outward—not a sound, but a void of it. The gentle rustle of leaves, the distant chirp of crickets, the very hum of the world itself was snuffed out within an instant, replaced by an unnerving, absolute silence. An isolator. Designed to mute all sound and sever any form of essentia-linked communication within its radius. They were now in a bubble of perfect, undetectable quiet.

The second operative then produced a third device: a sphere of brushed bronze that hovered just above his palm. Its surface shimmered to life, projecting a green, radar-like sweep of concentric circles. Dozens of faint, pulsing dots appeared on the display—the life signs of every sleeping student in the dorm.

A gloved finger traced the empty perimeter. “No one is awake. No patrols. The field is clear.”

A thin, predatory smile in the darkness. “Perfect.”

The night air grew cold and still, the only sound the soft scuff of their boots on the rooftop slate. They moved with practiced silence, two predators scanning the rows of darkened windows below.

"Here it is," the first shadow whispered, his voice a blade of sound in the oppressive quiet. He pointed a gloved finger downward. Through the glass, they could see two figures asleep in their beds. On the far side, Elliot slept turned toward the wall. And directly below them, lying perfectly still, was their target—Voidwalker Towan.

"Sorry to bother you."

The voice came from directly behind them. It was calm, conversational, and utterly impossible.

Both operatives whirled. The second shadow’s hand flew to his radar, his eyes darting to the screen. The green display still showed only the pulsing dots of the sleeping students in the rooms beneath them. The rooftop was, according to every reading, completely empty.

"But you can't be here," Professor Kaen finished. He stood bathed in a sudden shaft of moonlight, his features sharp and composed. He wore no weapon, made no threatening gesture. He simply stood there, where the radar insisted nothing stood.

"You said no one was around?!" the first shadow hissed, his knife held ready.

His partner could only stare, dumbfounded, at the device in his hand. He thrust the screen toward his companion, his own face a mask of disbelief. The radar’s sweep was clean. The rooftop was a blank, green field.

"...He... doesn't appear?" he stammered, his professional composure cracking as he finally looked from the impossible screen to the very real, very present man standing before them. The implication was a cold shock: their technology was useless. They were blind. And they were not the hunters on this roof anymore. They were the prey.

The night held its breath.

“An Essentia radar, huh?” Kaen’s voice was calm, almost academic, as his eyes flicked to the device in the operative’s trembling hand. A faint, disdainful smile touched his lips. “A pity. I don’t use such… crude energy.”

“…What?” the second shadow stammered, his mind struggling to process the statement. How does one not use Essentia?

“Abort the mission!” the first operative barked, his voice sharp with a fear that overrode all training. In one fluid motion, he spun and launched himself from the roof’s edge, a silhouette against the moonlit grounds, already calculating his escape route through the dark forest.

But as he turned to flee, Kaen merely lifted his hand.

A complex, shimmering rune—a geometry of pure, ancient power that hurt the eyes to look upon—flared to life above his palm. From its center, threads of incandescent energy, silent and searing, lanced out into the night.

“If that’s your choice…” Kaen said, his tone one of mild disappointment.

A bolt of silent lightning—a paradox of blinding light and absolute soundlessness—crossed the distance instantly. It didn't strike the fleeing man; it encased him. A cage of crackling, paralyzing energy froze him mid-stride, suspending him in a prison of light just inches from the sanctuary of the trees. He hung there, a statue of terrified potential energy.

The remaining operative stood rooted, his will to fight utterly shattered. “No way…” he whispered, the words a choked gasp. “Our files… our files say you were killed three hundred years ago!”

“You too?” Kaen replied, sounding almost bored. He turned his hand, the terrifying rune now orienting on the second shadow. “I’ve heard that many times already.”

(I gotta report this to Askael!) The thought was a scream in the operative’s mind. With a desperate, last-ditch move, he hurled a small orb to the rooftop at Kaen’s feet.

It erupted not with fire, but with a dense, grey, Essentia-charged smoke, designed to blind sensors and obscure all vision. In a heartbeat, the entire roof was swallowed by an impenetrable, swirling fog.

Kaen didn't even flinch. He simply exhaled a soft sigh that was somehow louder than the silence. “That isn’t enough to fool me.”

He walked forward, the unnatural smoke parting before him like a respectful curtain, refusing to even touch his robes. He reached the roof’s edge and looked down, his eyes pinpointing the faint, fading heat signature of the second operative, who was now desperately sprinting through the isolated bubble of silence.

Kaen’s hand extended.

FLASH.

A second spear of silent, precise lightning descended from the clear sky. It struck the runner just as he reached the treeline, the impact flawless and absolute. He crumpled without a sound.

The isolator artifact on the roof flickered and died.

Suddenly, the world rushed back in—the sigh of the wind, the chorus of crickets, the distant murmur of the night. Kaen stood on the edge of the silence he had not created, but had ended.

“Shouldn’t have isolated this space in the first place,” he commented to the empty night, before turning his back on the forest and its two fallen intruders.

Kaen stood for a moment longer on the precipice, a solitary sentinel against the moonlit sky. His gaze softened as it drifted back to the dormitory window below. Inside, the two brothers slept on, utterly unaware of the violent storm that had just been quelled mere meters from their slumber. Elliot had rolled over, one arm dangling off the bed. Voidwalker Towan lay perfectly still, his face peaceful, a stark contrast to the formidable presence he housed.

A faint, almost imperceptible smile touched Kaen’s lips. It was not a smile of triumph, but of quiet guardianship, a look worn by those who protect secrets too great to ever be known.

“You owe me one,” he murmured into the night, his voice a whisper meant for sleeping ears alone.

Then, as if he were a figment of the moonlight itself, he simply dissolved. There was no flash, no sound, no disturbance of air. One moment he was there, a silhouette against the stars, and the next, the space he occupied was empty.

Back in the silent library, a single page of an open book turned, though no window was open to let in a breeze. Professor Kaen was already seated at his desk, his expression once again that of a mild-mannered academic, as if he had never left. The only evidence to the contrary was the faint, lingering scent of ozone on the night air, slowly fading away
