Charon moved with the silent, fluid grace of a phantom. The service corridors of the Azure Dragon spire, a place of humming machinery and sterile plasteel, were his natural habitat.
He was a creature of the unseen spaces, of the paths that existed between the walls. To him, the fortress was not a bastion of power, but a complex, three-dimensional web, and he was the spider at its center.
He had studied the blueprints for weeks, memorized the patrol routes, and bypassed the security sensors with an ease that bordered on contempt.
The mission was simple: eliminate Elder Valerius, the loud, clumsy asset who had outlived his usefulness.
The ensuing chaos, the accusations that would fly between the clans, would be the perfect smokescreen for the Vanguard's next, larger move.
It was clean. It was efficient.
It was his art form. He reached the ventilation access panel for the main council chamber, a small, unobtrusive grate in a forgotten corner of a dusty maintenance shaft.
His senses, honed by decades of espionage and augmented by subtle Vanguard technology, told him the area was clear.
There were no energy signatures, no heat traces, no electronic signals. It was a perfect, silent approach.
But his finely-tuned instincts, the animal part of him that had kept him alive for so long, felt a single, infinitesimal tremor of wrongness.
It was like a single, discordant note in a flawless symphony.
He couldn't place it, couldn't define it, but it was there.
He paused, his hand hovering over the grate.
From their hiding place a level below, Ryu felt Charon's hesitation.
The spymaster's energy signature, once a cold, steady line, had developed a tiny, questioning flicker.
"He senses something," Ryu breathed, his voice barely a whisper.
"He's hesitating. Joric, are you ready?" Joric, his fingers a blur on his datapad, gave a curt nod.
"The trap is primed. But he has to be fully inside the vertical shaft. If he's even a meter outside of it, the effect will be diluted." Kiera held her breath.
The entire plan hinged on this moment.
It relied on Charon's arrogance, on his belief that no one could possibly be hunting him in his own hunting ground.
If he turned back, if he chose a different route, their chance was gone. Valerius would be killed, and they would be trapped in a fortress that wanted them dead.
In the maintenance shaft, Charon made his decision. He dismissed the feeling of wrongness as a ghost, a flicker of paranoia.
He was the apex predator here. There was no one who could touch him.
With a final, silent movement, he slipped the grate open and lowered himself into the vertical ventilation shaft.
The moment his feet left the corridor, Ryu gave the signal.
"Now." Joric slammed his hand down on his console.
The effect was not an explosion. It was far more insidious.
Deep in the bowels of the spire, Joric's override command slammed shut a series of critical valves in the atmospheric control system.
At the same time, it opened a primary coolant line, redirecting thousands of liters of super-chilled, liquid nitrogen gas, the same gas used to cool the clan's primary fusion reactor, directly into the council chamber's ventilation shaft.
The temperature inside the narrow, enclosed space dropped from a comfortable twenty-two degrees Celsius to nearly two hundred degrees below zero in less than three seconds.
It was not an attack; it was a flash-freezing. Charon, the master of stealth and subtlety, was caught completely, utterly, by surprise.
His advanced combat suit, designed to mask his heat signature, offered no protection against a sudden, absolute thermal inversion.
He had time for a single, choked gasp before the super-chilled gas hit his lungs. The moisture in the air flash-froze onto his body, encasing him in a thin, glittering layer of ice.
He was a serpent, trapped in a nest of his own making, and the world had just turned to absolute zero.
