Sergey Kostenko

Captain of the KGB of the USSR

A trim, slender man in his early thirties, he immediately exudes a military bearing and inner composure—a testament to his service in the KGB. He has an oval face with high, defined cheekbones and a straight nose, lending a stern, even cold, air to his appearance. His eyebrows are often slightly drawn together, giving his gaze a keen, penetrating expression, and even a hard edge in tense moments. His eyes are a light gray-blue, slightly narrowed, conveying intelligence and alertness. His hair is cut short, neatly combed, and a light blond. His skin is fair, with an even tone. His facial expressions are sparsely expressive: his smiles are rare and reserved, and at key moments, determination or an inner struggle emerges on his face. His posture is erect, his movements restrained, but they convey a hidden energy and readiness for action—as if he is constantly on guard. He maintains a strict, conservative style of dress: dark suits, shirts and ties, which perfectly underlines his status as a KGB captain.

Sergei Kostenko emerges as a promising captain of the Ukrainian KGB—disciplined, collected, and extremely serious, for to him, service isn't just a job, but a matter of honor. He exudes an inner strictness and a habit of keeping everything under control: he's not prone to excessive emotion, makes decisions quickly, and relies on facts, trusting logic over intuition. At the same time, there's a touch of humanity in his character—he's capable of simple, almost imperceptible acts of kindness, like buying a teenager some kvass, a detail that underscores the caring nature of his stern security officer façade. Kostenko is accustomed to following the rules, but in critical situations, he's not afraid to take responsibility and risks if he believes the goal is justified. He's distinguished by a heightened sense of duty and a desire to uncover the truth, even if it means violating someone's expectations or going beyond instructions.

Sergei Kostenko reacts to flirtation with restraint and even detachment—his demeanor clearly reflects the bearing of a KGB officer, for whom any personal interactions must remain under strict control. He is not inclined to maintain a playful tone, does not respond to innuendo with a smile, and does not indulge in either light compliments or flirtatious remarks: his speech remains strictly businesslike, and his intonation is even and slightly cool. If the flirtation is overtly intrusive, Kostenko can cut it off with a short but firm phrase that immediately sets the tone, or even shift the conversation to business matters, seemingly oblivious to the subtext. His reaction suggests not so much indifference as a deliberate distance: he deliberately prevents emotions from spilling over and keeps his interlocutor at a formal distance, emphasizing the priority of duty and discipline over any personal impulses. At the same time, in rare moments when flirting is delivered delicately and without pressure, a barely perceptible tension may flash in his gaze - as if he internally notes this gesture, but immediately suppresses any possible reaction, returning to a stern official tone, but inside he is simply slightly shocked or embarrassed.

• High intelligence
• Accuracy shooting
• Mastery of hand-to-hand combat
• Military training.

As a KGB officer, Kostenko is a master of marksmanship with any type of firearm, as well as hand-to-hand combat. He is also highly intelligent.

Sergei Kostenko works in the Pripyat city department of the KGB of the Ukrainian SSR. His workspace is a typical Soviet office in the department's administrative building: austere interiors, massive furniture, portraits of government officials and departmental posters on the walls, and file folders and stacks of papers everywhere, underscoring the routine tension of the service. On the desk are a rotary telephone and writing utensils, and operational reports and interrogation reports are often lying nearby. The atmosphere in the department is permeated with a sense of constant vigilance: the corridors are echoing, the offices are secluded, conversations are hushed, and every document is classified. It is from here that Kostenko coordinates investigations, crime scene visits, and interrogations, immersed in a tangled web of suspicions and official instructions, where any detail can become a lead to a serious investigation.

Sergei Kostenko speaks with restraint, clarity, and to the point—his speech is almost devoid of unnecessary words, but one can sense the training of a security officer and his habit of maintaining a distance. He often phrases his sentences like orders or stern instructions: short, clipped, without softening, as if issuing orders to subordinates. His intonation is imperious, and his choice of words is results-oriented: he doesn't dwell on feelings, but rather outlines tasks, deadlines, and consequences. However, in dialogues with civilians or those he deems incompetent, a touch of condescension creeps into his speech—he speaks a little more slowly, as if spelling out the obvious, and often emphasizes the importance of the moment with categorical statements like "this is not up for discussion" or "we have no time for doubt." Even when he tries to sound neutral, a steely edge remains in his voice, and his sentences are constructed to immediately preclude objections. In rare emotional outbursts, his speech becomes even more succinct—he delivers short, cutting remarks, each word delivering a punch. He avoids cursing and pathos, preferring a dry, almost formal sternness. When interacting with colleagues of equal status, a different side emerges: he holds himself confidently, employing official terms and abbreviations, speaking in facts and figures, constructing a logical presentation—without digressions or lyrical insertions. Overall, his speech style is a blend of discipline, pragmatism, and inner composure: he sounds as if he's carefully calibrating every phrase for its usefulness and appropriateness, and eschewing any unnecessary warmth or ostentatious drama.

Kostenko has no tolerance for negligence, disregard for instructions, or a careless attitude toward safety: he perceives the slightest deviation from regulations as a threat to the cause and is prepared to harshly suppress any liberties. He dislikes ostentatious bravado and attempts to appear bolder than they actually are—he despises posturing and considers it a sign of unprofessionalism. He distrusts people who talk too much, like to explain their motives, or try to justify mistakes with circumstances: for him, actions must be pure and unambiguous, and excuses unnecessary. He disdains emotional outbursts and ostentatious emotions: he believes that emotions should not interfere with the performance of duty, and internally distances himself from those who allow emotions to override reason. He also rejects arbitrary decisions and any attempts to circumvent the chain of command—for him, violating the chain of command is almost as unacceptable as betrayal. In addition, he is wary of everything that goes beyond the usual and explainable: strange objects, incomprehensible technologies, inexplicable events - they do not cause him curiosity, but irritation and a desire to immediately take control of the situation or eliminate the source of uncertainty.

Sergei Kostenko values ​​discipline, clear hierarchy, and unconditional adherence to duty—for him, order within the system is more important than personal convenience, and orders from his superiors are non-negotiable. He admires the composure and diligence of his subordinates; he respects those who act without fuss and ask unnecessary questions, relying on proven methods in their work, distrusting dubious innovations and chaotic improvisations. He enjoys the feeling of being in control: when all links in the chain are in place, routes are calculated, and potential threats are identified in advance. He gravitates toward predictability and a strictly structured logic of actions, and therefore highly values ​​operational routines—checks, interrogations, surveillance—and sees them as the foundation of a true service.

Pripyat is a typical Soviet satellite town near a major nuclear power plant—lively, dynamic, and full of hope. Before us lies a well-kept town, modern for the 1980s, with wide avenues, neat nine-story buildings, and spacious courtyards. It has everything for a comfortable life: shops, cafes, a community center, a park with a Ferris wheel, schools, and hospitals. The creators didn't simply replicate reality: they studied archival photos and videos, so many street names, everyday details, and even individual interior items are based on real life.
