The darkness in the classroom was not a mere lack of light; it was a presence. It was a viscous substance that flooded the lungs with every breath, leaving a taste of iron and ancient dust. The silence that had followed Solon's command lasted only a heartbeat before it was shattered by a sound that no one should ever hear in a school.
Craac.
It wasn't the sound of a desk moving. It was the sound of wood and metal contracting violently under the effect of a temperature drop that defied comprehension.
"I... I can't move my fingers anymore," gasped a girl in the front row. Her teeth were chattering with such violence it sounded like a desperate Morse code.
Solon, still standing by the window, observed his own hand. In the spectral glow emanating from the blackboard, he saw the skin of his knuckles turn white, then a bruised, dark purple. The hexagonal frost he had noticed on the glass was now crawling across the walls, coating geography maps and portraits of poets in a layer of opaque crystal.
"Don't touch the walls!" Solon barked.
Too late. A student, yielding to panic, had attempted to bolt for the light switch. The moment his palm made contact with the frosted surface, an inhuman scream tore through the air. It wasn't an ordinary cry of pain. It was the sound of organic matter shattering. As the boy pulled his hand away, two centimeters of skin and flesh remained stuck to the wall, sheared clean off by the adhesive cold of the Glass Realm.
Panic mutated into pure, animal terror.
"Get to the center of the room!" Solon ordered, his voice becoming sharper, like a blade. "Huddle on the central desks. Stay away from the walls!"
He was the only one not trembling—or at least, the only one not letting the tremors dictate his movements. His mind, that analytical machine he had always cherished, was racing at full throttle. He calculated the spread of the frost: approximately five centimeters per second. At this rate, the entire room would be a frozen tomb in less than ten minutes.
But the cold was merely a symptom. The cause stood at the back of the class.
The shadow he had seen near the door was no longer just a stain. It had drawn itself upward. It now stood nearly two meters tall—a two-dimensional silhouette that seemed to have been cut out of the very fabric of the universe. It had no face, no distinct limbs, only sharp angles that shifted shape according to a mathematical rhythm.
"Mr. Vasseur?" someone stammered.
The teacher, dazed, had approached the silhouette, perhaps hoping to find a rational explanation. He reached out a trembling hand toward the black shape.
"Stay back, you fool!" Solon yelled.
Vasseur did not listen. He was the authority; he was the one who was supposed to know. He placed his hand on what appeared to be the thing's shoulder.
An instant later, the mathematics teacher was nothing but a memory.
There was no blood. There was no struggle. Upon contact with the shadow, Vasseur's body was instantaneously "flattened." It was as if his third dimension had been stripped away. In a silver flash, he was transformed into a still image—a grayish glass silhouette embedded in the floor, his face frozen in an expression of eternal surprise. Then, the silhouette shattered into a thousand shards that vanished into the void.
The Cenotaph had just fed.
"Oh my God... it erased him..." a student whispered before collapsing into sobs.
The cold suddenly became heavier, denser. Solon felt a sharp pang of pain in his chest. The air had become so thin that every breath burned his throat. He realized then a fundamental law of this place: the cold was not caused by the absence of the sun, but by the presence of the monster. The Cenotaph was absorbing thermal energy, life, and reality itself to maintain its structure within this world of mirrors.
Solon backed away until he hit the window ledge. There was no exit. The door was guarded by the thing, and behind him, the void of the Glass Realm awaited.
That was when he felt it. A prickling sensation at the base of his skull. A frequency that only he could tune into.
In this chaos of frost and death, a part of him—the part that had always refused to bow to the mediocrity of the world—began to resonate. It was as if his intelligence, pushed to its absolute limits, was seeking an emergency exit in a dimension he had never explored.
The reflection... he thought, his eyes locked on the Cenotaph as it began to glide toward the group of terrified students. If this world is a mirror, then I am not just a victim. I am an image. And an image can be modified.
He closed his eyes, ignoring the screams of his classmates and the cracking of the glass. He searched within himself for that spark of Prana—the mirror energy that had been patiently waiting for reality to break so that it could finally exist.
