Chapter TWO · Tide’s Tango

Consciousness returned to Santali on a spike of acute pain.

The pain was peculiar—not the sharp tear of the wound, but a deeper, liquid burn that seemed to seep backward along the nerve pathways, as if a syringe of low-temperature flame had been emptied into his veins. The anticoagulant component of the NTX toxin was dismantling his microcirculation; he could feel the fine rupture of subcutaneous vessels like the sensation of countless red-hot needles between muscle and fascia, slowly burrowing and scorching.

He kept his eyes closed.

Awareness rose like a diver from the abyssal depths, gathering intelligence on the ascent. The feel of dry, clean fabric against his skin. The subdued hum of central air. The scents of antiseptic and… blood. And something fainter, barely there—a cold, sharp essence, like frost on a windowpane at dawn.

His fingers traced a minute path across the surface beneath him—a high-grade cashmere blend. Italian. Bespoke. The armrests bore subtle wear, yet were meticulously maintained. The safe house owner had taste. And caution.

Primary datum: he was alive. The wound bore a professional-grade pressure dressing.

Assessment:

Identity: conspecific (probability > 0.8).

Motivation: obscure.

Threat Level: Tentatively Code Yellow.

Initial scan complete, Santali sharpened his focus. His hearing came online first—the faint, precise sound of a page turning, five meters at three o'clock. The paper had heft; likely a file or chart. Next, smell. Beyond the baseline, came the faint, sweet aroma of warmed milk.

Finally, vision.

He cracked his eyelids. Darkness. Not an absence of light, but the total, physiological void of a severed signal. The retinal burn had faded into numbness—textbook optic nerve trauma. The Arcana recoil had a ~20 minute delay. How long was I out?Judging by blood loss and the throat-parched dryness from mouth-breathing, at least four hours.

Estimated blindness duration: 48 to 72 hours.

The knowledge lodged in his gut like cold iron, but his expression did not flicker. Years of training had rendered emotional control autonomic, as natural as breath.

“Awake.”

The voice came from his three o'clock. Neutral, deliberately lowered, yet Santali discerned the precision beneath—female, under twenty-five, healthy vocal cords untouched by smoke or liquor.

His face assumed that practiced, harmless smile. He turned his head slightly toward the sound. His unfocused violet eyes resembled dust-covered gems in the light.

“A pity… for such beauty to witness this disarray.”

As he spoke, his right hand rested casually on the couch arm, fingertips tapping twice in an almost imperceptible rhythm. A probe—a professional would note the anomalous frequency; to anyone else, a nervous tremor.

X leaned against a lab bench, a freshly prepared syringe in hand. Her gaze settled on his face, lingered on those sightless eyes, then dropped to his tapping fingers.

Morse: .. / .-(I A)

Nonsense, or a test. She offered no reaction, placing the syringe on the glass table and sliding it forward. Glass on glass sounded stark in the silence.

“The wound is sutured. Couldn’t source official NTX antiserum in time. This is… improvised.” Her tone remained flat, a clinical report. “Seeking patient consent. Do you want it?”

Santali caught the syringe with precise timing—guided by sound, trajectory, the shift of air. His thumb brushed the barrel, gathering data.

-1ml disposable. 25G. Solution temp: 12.3°C. Chilled, not ambient.-

He uncapped it, collected a bead of solution on a fingertip. He didn't sniff it overtly. Instead, he smeared it casually on his hand, then, under the guise of shifting position, brought the back of his hand near his face.

-Odorless. Viscosity elevated. Optical clarity >98%.-

“The LD-50 of your bespoke serum? Adverse effects?” he inquired, tone airy. Concurrently, he blotted the residue into the couch fabric—a toxicological sample, should this be a poison.

X noted the micro-gesture. A flicker of something akin to interest crossed her eyes, then vanished. She turned back to the bench, preparing a second vial.

“Both unknown. You’d be the first trial.” A pause, the air seeming to congeal. “You can refuse. The door is that way. S. Clean work. Poor timing—”

The last few syllables fell softly, like a stone into still water.

Santali's fingers tightened infinitesimally. The plastic syringe creaked under the strain.

-She knows my designation. Source: 'Crimson Tide' leak? Or higher clearance. Using the codename: maintaining distance, acknowledging value. A surface threat, a practical test.-

He relaxed his grip, the smile on his face unchanged, even brightening slightly, the expression reaching his eyes with practiced ease. “NTX triggers DIC（disseminated intravascular coagulation） and multi-organ failure within forty-eight hours.” He lifted the edge of his shirt, revealing the professionally dressed wound. “I’ll be your sample.” Then he added, “Need a baseline blood draw, Doctor?”

—The question served three purposes:

one, compliance with medical procedure; two, addressing her as 'Doctor' to frame their interaction within a temporary, functional contract; three, a logical, veiled probe—requesting a standard safety check implied a expectation of professional protocol, testing her response.

X turned. She held a second syringe, now wearing sterile gloves. Her movements were economical: tearing the packaging, drawing the solution, expelling air bubbles.

“Unnecessary.” She approached, standing at an angle that placed her above him, yet Santali sensed her focus wasn't on his face, but on his abdominal wound. “Serum volume sufficient. A tenfold dilution allows for periwound infiltration. Success probability: 89%. Failure risk: procedural disruption of the vascular barrier may accelerate systemic toxin dissemination.”

Hn... craft is professional; intent isn‘t.

The earlier comment now resonated as a final test. A probe of his willingness to trust in extremis, or more precisely, the degree to which he would cede control to an unknown variable with intent for the chance to survive.

She reached to remove the bandage. Her technique was professional, fingers avoiding the wound area, peeling back the layers from the edges. Santali felt the slight sting of the dressing separating from his flesh, but he didn't flinch. Only his abdominal muscles contracted instinctively for a fleeting moment before he forced them to relax.

The bandage came off, revealing the wound beneath. The suturing was impeccable—3-0 absorbable suture, even spacing, clean wound-edge approximation. But the surrounding skin was a mottled purple, non-blanching upon pressure—signs of tissue necrosis and hematoma.

“I pulled your file off Crimson Tide,” X stated, preparing the injection apparatus, her voice as level as if reading a lab report. “Some… inconsistencies were noted. Our objectives may have points of convergence.”

She looked up, her gaze meeting his eyes. Those unfocused violet orbs seemed to ‘look’ back, creating an illusion of deep insight despite their blindness.

“Consider a limited collaboration. In our line of work, there are no permanent enemies, only permanent interests.”

Santali remained silent for precisely 2.7 seconds—a calculated duration, short enough to avoid seeming hesitant, long enough to avoid appearing rash.

Then he moved. His hand rose, not fast, but with a trajectory so precise it closed around the wrist of her hand that was tending his wound. The grip wasn't forceful enough to cause pain, but sufficient to halt her movement.

“Cooperation is acceptable,” he said, his voice lowering. The jade-like facade developed fine cracks, revealing something cold and sharp beneath. “But I require the terms of exchange—what you offer, and what you require in return.”

X’s wrist twitched, employing a specialized technique—not a brute-force, but a fluid rotation, slipping free like an eel. The motion was swift and subtle, invisible to most operatives.

“I offer seventy-two hours of absolute security, professional medical support, and partial intelligence on the ‘Nightwatchers’ system,” she stated, resuming her work. The needle pierced the edge of the necrotic tissue. “In return, I require the complete decryption of page seven of the Crimson Tide file, and… your interpretation of his final words.”

Santali’s breathing rhythm altered for 0.8 seconds.

-She knows page seven is encrypted; knows Crimson Tide spoke before dying. Intel source clearance level… significant.-

“Deal,” he said, this time without hesitation. “But I require confirmation of the serum’s safety profile—I’ll be the test subject, but you disclose the composition.”

A reasonable bottom line. X nodded, retrieving a sheet of paper from the bench covered in handwritten chemical formulae.

“Primary component: Synthetic prothrombin complex concentrate, dosage 1.3 times standard, to counter the NTX anticoagulant effect. Excipients: Custom cryoprotectant matrix to reduce frostbite risk; neuro-sedative component, minimal dose, targets peripheral pain pathways only.”

Each word was clear, cold, falling into the quiet room like surgical instruments being laid out on a sterile tray. This wasn't an explanation; it was a demonstration.

Santali's mind raced through calculations: NTX half-life, his own clotting factor levels, potential hepatic/renal impairment…

—Prothrombin complex overdose risked thrombosis, but the NTX would counteract it; the theoretical balance point was between 1.2 and 1.5 times. So 1.3 was precise, with adjustment margin. The neuro-sedative… to prevent shock, or something else? Red-flagged unknown.

“Proceed,” he finally said.

As the needle penetrated the wound, pain lanced up his neural pathways. Santali bit the inside of his cheek, the taste of iron spreading. The habitual, faint smile miraculously remained on his face, though fine beads of sweat rapidly formed on his temples.

The sensation of infusion was peculiar—first an icy chill, then a heat, followed by a numbness spreading from the injection site. The pain became muffled, distant, as if viewed through frosted glass. He could feel it—not through touch, but via his aerokinetic sensitivity to fluid dynamics—the deeply necrotic tissue, starved by toxin and ischemia, was slowly dissolving and separating under the drug's influence.

Fresh blood, with faint pressure, began reperfusing the microvasculature.

“Crimson Tide file, page seven. Physical encryption,” he began, voice trembling slightly but clear, during a lull in the pain. “Triple-layer composite. First layer: Caesar cipher, shift 7. Second layer: Rail fence cipher, key 3, but read sequence is serpentine, starting top-right. Third layer…”

He paused, not from hesitation, but as an intense, cramping spasm seized his abdominal muscles, stealing his voice. X’s hand remained perfectly steady, ceasing injection the moment the spasm began. Her left index and middle fingers pressed firmly against his femoral pulse point—less a medical gesture, more a battlefield technique to control blood flow and slow local drug metabolism.

Thirty seconds later, the spasm subsided.

“Third layer,” Santali gasped, “is image steganography. The plaintext from the first two layers must be converted to ASCII binary stream, then mapped onto the least significant bits of the RGB values of a specific baseline star chart…” He recited a string of precise, seemingly random coordinates and a deep-space chart designation.

X noted it, but did not immediately verify—that would be too eager, revealing her true need.

“Crimson Tide’s final words?” she asked, continuing the injection.

“‘The key awaits at the altar’,” Santali replied instantly, without concealment. Then, his purple eyes turned toward her. “Verbatim. Repeated three times.” He paused, subtly returning the probe. “Do you know… what the ‘key’ and the ‘altar’ specifically refer to?”

X’s hand hesitated almost imperceptibly. The syringe was nearly empty, about 0.2 ml remaining.

“‘The key’… may refer to an individual with a specific genetic marker, or an unstable dominant Arcana genotype. Data is scarce and contradictory,” she finally answered, her voice still even, though her pace seemed slightly measured, as if choosing words with care. “‘The altar’… associated intel is vague. Probable location points within the Arctic Circle.”

With that, she steadily injected the last of the fluid, withdrew the needle cleanly, and began re-bandaging. Her movements were more meticulous than before, the pressure even, almost… gentle.

Santali allowed her to proceed. He sank back into the couch’s unyielding cushions, letting the tension drain from his body, tracking the drug’s passage through his system as the sharpest edges of pain receded. In its wake rose a profound fatigue, seeping from the marrow of his bones. Alongside it, a strange, unfamiliar sense of stillness—not safety, but the grim respite of finding a makeshift shelter from a storm, even if the owner of the roof remained a mystery.

“One last question.” His eyes remained closed, his voice lowered by weariness yet cutting directly to the core. “Why extract me? Letting me die in that alley, taking whatever you wanted… it would have been simpler. Lower risk for you.”

The bandage was secured, a clean surgical knot tied. X took two steps back, peeled off the bloodied disposable gloves, and dropped them into a biohazard bag. She turned to face him, her expression still unreadable, like the surface of a lake thinly iced over.

“Two reasons,” she stated, her voice resuming its neutral chill. “First, a live, potentially cooperative intelligence source holds more value than a corpse. You are currently the only person who has made direct contact with Crimson Tide’s final intelligence and succeeded in decrypting part of its encryption. Your mind is more critical than any storage device.”

A rational calculation. Santali listened in silence.

“Second,” she paused briefly, her gaze sweeping over his pale face before fixing on a point in the middle distance, as if weighing her words or stating a simple fact, “ ‘Crimson Tide’… I was the one who terminated him. His effects are, technically, my ‘spoils of war’.” Her voice dropped lower, acquiring a terse, possessive edge. “I don’t like others touching what’s mine.”

The answer was a blend of truth and obfuscation; Santali could hear it. He didn’t press, merely giving a slight nod.

“Understood. Then… a productive partnership, Doctor.”

“Call me X,” she corrected, turning towards the kitchen. “You need rest. The serum requires six hours for full integration. I’ll prepare something liquid.”

After she left the living area, Santali slowly opened his eyes—still to absolute darkness. He raised a hand, tracing an invisible pattern in the air.

At his will, the air currents stirred, swirling, coalescing into a line of minute beads of condensation upon the couch’s velvet armrest. The beads slid, arranged themselves, forming a line of cipher legible only to the wind:

[Test passed. Provisional security status: Blue.]

With a dismissive wave of his hand, he scattered the moisture, the message vanishing as if never there. Then he let himself sink into the couch, fully yielding to its embrace.

Outside, over Moscow, the sky was beginning to lighten.
