The "Prana Fluid Dynamics" lecture had been droning on for forty minutes. Inside the elite auditorium of the Exorcist Academy, the air was thick with the hum of air conditioning and the rhythmic tapping of laptop keys. Alistair, the group's natural-born leader, leaned back in his chair, staring at the watch on his wrist. To him, this was all boring theory. He yearned to be back in the field, hunting anomalies, feeling the heat of his own power coursing through his veins.
Beside him, Selena was taking notes with frantic precision. She had been feeling it since dawn a mounting pressure in her sinuses, like the heavy air before a hailstorm.
"Don't you feel that?" she whispered to Thales and Yuna, who were sitting in the row behind her.
Thales, the technical genius of the group, didn't look up from his tablet. "Atmospheric pressure is dropping by 4 hectopascals per minute. It's likely a localized disturbance caused by the Agency's stasis drills in the basement. Nothing to—"
He cut himself off. His tablet screen had suddenly gone pitch black, save for a single line of silver code scrolling in an infinite loop: [SYSTEM_OVERRIDE: ARCHITECT_LOGIC].
Suddenly, silence fell. A total, suffocating silence. The hum of the AC, the murmurs of a hundred students, the scratching of pens... it all vanished. Even the beat of their own hearts seemed muffled, as if wrapped in cotton. Outside, the rain that had been lashing against the roof a second ago stopped instantly.
The four students stood up as one and rushed toward the massive floor-to-ceiling windows overlooking the city of Lyon.
What they saw froze the blood in their veins.
The rain was no longer falling. Millions of droplets were suspended in mid-air, frozen in place, turning the sky into a forest of jagged crystal pearls. Time hadn't stopped; it had been recalculated.
Then, the columns appeared. At the four cardinal points of the district, pillars of violet light erupted from the sewers, piercing the asphalt like the lances of giants. Within seconds, a translucent membrane, etched with glowing silver circuitry, rose to meet the clouds.
The sky, usually a dull gray, turned a spectral electric purple. Lyon had vanished behind a wall of pure geometry.
"We're trapped," Yuna whispered, her hand instinctively gripping the hilt of her short blade. "This isn't an Agency barrier. It's... it's a cage."
Through the glass, far off in the Place Bellecour, they spotted a figure. A man walking alone, clad in a long black coat that seemed to swallow the dim daylight. With every step he took, the world around him transformed. The asphalt turned to glass; the streetlamps twisted into impossible fractal arches.
Behind him, three forms emerged from the shadows like nightmares made manifest.
Raphael, Muriel, and Azrael did not walk; they glided, their mere presence causing the windows of parked cars to shatter in their wake. For the four students, the recognition was a physical shock.
"It's the anomaly from the sewers," Alistair growled, his hands igniting with an unstable blue flame. "Solon... he isn't dead."
Suddenly, the classroom intercom, which had been disconnected for years, crackled to life. A cold, emotionless voice a sound like grinding glass echoed through the entire academy.
"Alistair. Selena. Thales. Yuna. You spent six months studying me like a lab rat. Today, I am changing the protocol. Welcome to the architecture of your own end."
The ceiling of the auditorium began to spiderweb with cracks. Stalactites of black ice began to grow instantly along the walls. Muriel had activated her Demonium of Frost on the ground floor, and the cold was climbing the building's structure like a virus.
"We have to get out of here!" Thales shouted. "If the Mirror World saturates the building, we'll be fused into the walls!"
As they lunged for the exit, the heavy oak doors were torn from their hinges by a seismic shockwave. Raphael stood in the hallway, his fist still smoking with ochre energy. The colossus of geometry looked at them, and the floor beneath their feet began to liquefy into jagged shards.
The war wasn't at their gates. It was already inside their sanctuary.
