Yuri’s mouth opened, but no sound emerged. His pupils contracted violently, as if witnessing something utterly horrifying.

X and Santali exchanged a glance—a complete sentence. He’s hiding something critical.

But there was no time for interrogation. Santali checked his wrist unit and stood. “We move in forty-two minutes. X, final check on the sleds. Mr. Yuri…” He leaned down, patting the old man’s shoulder with a gentleness reserved for a child. “Try to remember. Your life is tied to ours now. We breathe, you might breathe. Understood?”

Yuri nodded, a mechanical jerk.

As Santali turned toward the snowmobiles, X’s voice came from behind, now close at his shoulder. “You seem… excited.” Her proximity was almost a touch. “Facing a potential trap, a normal reaction is caution.”

Santali tilted his head. In the lamplight, their shadows were welded together on the ice—a pool of twin darknesses that seemed to stain the frozen surface.

“Shouldn’t I be?” he murmured, as if confiding a delightful scandal. “Thirty below. Mechanical nightmares. A hidden fortress guarding humanity’s ultimate secret… Infinitely more compelling than ‘sawing’ away at a violin in some opera house.”

His eyes crinkled, his smile inappropriately brilliant—a man dressing for a ball, not a battlefield.

X was silent for two measured heartbeats. Then her hand rose. Her index finger brushed the fine cut on his cheek—sustained during the day’s scramble along the ice ridge. Her touch was cool, with the dry, clinical texture of surgical rubber, slow and light.

"Pity." The words left her on a breath as cold and fine as gossamer, skimming the shell of his ear. "A face this lovely, marred. Your future in a dress would lack its… flawless charm."

Santali’s smile stilled for a half-beat, then reignited, even brighter. “Is Dr. Anna worried for me?” he asked, using 'Lev's' earnest, hesitant tone, though his eyes curved into sly crescents. "Don't fret. I brought scar gel. And besides…"

He inclined forward, a fraction that brought the warmth of him into her space.

“Imagine. A delicate line, tracing the cheekbone of a beauty in a Silk-Sheath… wouldn’t it add a certain… tragic romance? Make her utterly… unforgettable?”

X’s hand hung suspended for a second. A faint tremor passed through her lashes. She retracted her touch and turned away.

“Pervert.” She moved toward the snowmobiles, her steps crisp.

But Santali saw it—in the moment she turned, the pale curve of her ear, nearly translucent against the crimson of her hair, flushed with a sudden, vivid warmth, like a streak of sunset igniting a frozen plain.

He remained, his smile lingering like a secret.

Interesting.

Nearby, Yuri’s gaze darted between them, brimming with pure, uncomprehending bewilderment. He pulled his scarf higher, suddenly feeling that the chill in the air had been displaced by something far more… convoluted.

These two people… one moment dissecting deadly threats with surgical calm, the next seamlessly engaging in this… flirtatious banter. Was this the psychological armor of elite operatives? Or simply a more refined madness, unique to those who danced with death?

Forty minutes later, they were ready. The snowmobiles had been coated in matte arctic white and fitted with dual-stage suppressors. All three had pulled on full winter camouflage gear. X disassembled her sniper rifle and secured it in a specialized carry-case strapped to her back. Santali checked and sorted every round of ammunition, then performed an action that made Yuri frown: he retrieved a small canister from the equipment pack, attached a thin hose, and began spraying a colorless gas over the cartridges.

“What’s that?” Yuri asked, unable to curb his curiosity.

“Liquid carbon dioxide,” Santali said, his fingers deftly loading the treated rounds into a magazine. “Forms a micron-thick dry ice layer on the casing. Vaporizes upon firing, briefly alters the local air density and temperature. Combined with my… specialized techniques, it stabilizes trajectory or creates a bit of misdirection.”

He didn’t say Arcana, but X understood.

He didn’t say Arcana, but X understood. She flicked a glance his way but said nothing, merely performing a function check on her own Glock—her sidearm received no such treatment.

“We split up,” X declared, her voice slicing through the cold air and preempting any further query from Yuri. “Once inside the facility, I operate alone.”

Santali’s hands went still for a fraction of a second, hovering over the magazine. “Reasoning?”

“Three primary zones. Separation is tactically efficient,” she said, her tone leaving no room for debate.“And our covers don’t match—you’re the academic, I’m the asset. A trio draws eyes.”

The logic was flawless, but Santali knew it wasn’t the whole truth. X was withholding. Or probing. He didn’t press, offering only a curt nod.

“Encrypt comms to the highest protocol. Status checks every ten minutes. If you’re silent for three minutes past the check-in, we assume you’re compromised.”

“Understood.” X pulled her frost-rimmed goggles down, swung a leg over the lead snowmobile. “I’ll take point. Follow in three minutes. Maintain five hundred meters.”

The engine growled to life. She sped into the night, the machine carving a pale scar across the moonlit ice before disappearing behind a jagged pressure ridge.

Santali watched the emptiness where she had vanished. The habitual, easy smile slowly bled from his face. He turned to Yuri, his eyes regaining that unfathomable, still-water calm.

“Our turn.”

The arctic night was breathing.

This was no metaphor. As Santali and Yuri glided across the snow, they could feel a pulse beneath the ice—a slow, heavy throbbing like the heartbeat of a colossal beast. The wind lashed snow into swirling phantoms that glowed under the moonlight, a spectacle both breathtaking and lethally disorienting.

The first wave of the Sentinel materialized on the thermal scanner three kilometers out. X's warning came through the bone-conduction earpiece, her voice as calm as a weather report: "Two o'clock. Five units. Speed, four meters per second. Visual contact in two minutes. Recommend a detour left of the pressure ridge."

Santali adjusted course. The snowmobile arced into the shadow of an ice mound. He retrieved the VSS from its case but didn't assemble it immediately. Instead, he closed his eyes, his fingers tracing faint patterns in the air.

Yuri watched, baffled. Then he felt the change—the wind shifted.

The breeze, previously slicing in from the port side, died, then rose anew from ahead, flowing deliberately toward the Sentinel's last known position. It gathered the luminous snow mist, weaving it into a dense, drifting curtain that swallowed their thermal plume and engine exhaust whole.

"Move," Santali opened his eyes. The snowmobile glided forward. They skimmed the edge of the patrol route, passing within less than a hundred meters at the closest point. The bio-mechanical hybrids showed no awareness, continuing their mechanical sweep.

Yuri glanced back, a chill settling in his gut. Not because of the Sentinel, but because of Santali's casual gesture—no visible energy surge, no sound, just the wind obeying. What kind of technology was this? Or was it…

He didn't dare ask.

The rest of the journey passed relatively smooth. They avoided three more patrols and reached the outskirts of the target facility at 04:21. The structure loomed larger than the maps indicated, and more… grotesque. Its hemispherical black shell resembled the carapace of some colossal beetle. Most of the solar panels studding its surface were shattered, and the antenna array was twisted at unnatural angles.

There were no windows, no obvious entrance—just a single, unremarkable airlock on the flank, marked by a faint, pulsing red diode.

The surroundings made Yuri's stomach lurch, bile rising in his throat.

The ice here was no longer pristine. Scattered across it were not mechanical debris, but things that had once been ‘flesh’. Frozen limbs, sickly with a bluish-purple pallor, lay like discarded parts of some malformed doll. Half-thawed masses of tissue glistened with the dull sheen of offal, their surfaces writhing with vein-like protrusions. Occasionally, relatively intact skeletons could be seen, but their forms were twisted—spines with extra segments, ribs growing in spirals, empty eye sockets, and jawbones mutated into pincer or sucker-lined maws.

Some of the remains were still "moving." Not the struggle of life, but the irregular twitching caused by internal decomposition gases, or the slow, maggot-like curling of not-yet-dead nerve endings. One particularly shapeless lump of matter had dragged itself across the ice, leaving a glistening, translucent trail.

Further away, several of the Sentinel were conducting methodical "clean-up." They used their mechanical claws to shred the still-quivering matter before…… tossed them into a gaping pipe on the building's side. From the depths of the pipe came sounds: wet, heavy grinding, viscous tearing, and the intermittent, crisp crunch of bone being pulverized.

"They're feeding," Santali observed, his tone still unnervingly calm. "Feeding whatever's inside."

Yuri clamped a hand over his mouth, swallowing convulsively.

X's voice came through then: "I'm in position. At your ten o'clock, three hundred meters, on the ice mound. Two live guards at the airlock, in full hazmat gear, armed with KRISS Vectors. Suggest you enter via the ventilation shaft—ground level, rear of the structure, disguised as an exhaust grate."

Santali adjusted his binoculars. He saw it—a grate, but impossibly small, perhaps fifty centimeters across. He and Yuri might barely squeeze through, but with their gear, it would be tight.

"What level of access?" Santali asked.

"Split up," X continued. "I'll clear the guards, create a three-minute window. Once you're in, I'll head to the main entrance—I have an access card, obtained from 092A."

"What level of access?" Santali asked.

"Not important." X paused. "Rendezvous in ten minutes at the main ventilation junction. If I'm not there…"

"I'll blow the place up looking for you," Santali finished, his tone as light as if suggesting an after-dinner stroll.

A faint, almost inaudible laugh came through the earpiece. "Fine. Suit yourself."
