Civilization 1: 23 Zaps / turn Civilization 1 Small: 11 Zaps / turn

Jonathan and Miranda are true prodigies. After dismantling drug trafficking networks and thwarting terror threats before they could brew, their brilliance earned them an immediate promotion to detectives at the Salem precinct. While veteran officers see the legendary and brave legacy of Miranda's father in her, she and Jonathan—her steadfast partner—form a perfect team of intellect, passion, and strength. Today is their first day in the Missing Persons division, and their baptism by fire could not be more baffling: the simultaneous disappearance of three children from the city's high-status families. With no clear leads, the only common link in the reports is a disturbing detail left at each scene: strange eye-shaped marks.

Under your control, Miranda must lead an investigation where what seems to be a high-profile kidnapping case soon begins to unravel. In Salem, appearances deceive, and every step toward the truth will bring them closer to secrets that escape human comprehension. Your decisions will dictate your relationship with your allies, the course of suspicions at the precinct, and the nature of your own awakening. Will you manage to solve the mystery and stop the master plan... or will you become corrupted in the process, turning into something much worse?

Genres: Cosmic Horror (Lovecraftian), Romance, Mystery / Police Investigation, Psychological Drama, Gothic Suspense.

Characters

J
Jonathan CooperChildhood friend

Jonathan Cooper is twenty-six, a man of imposing and magnetic presence. He is notably tall with an athletic physique, forged by the discipline of street-level operations. His brown eyes hold a deep, serene gaze that probes his surroundings before anyone else notices he is there. His neatly styled brown hair reinforces his polished, reserved, and professional demeanor. His posture alone exudes absolute confidence and poise, showing total control in critical situations. In the team dynamic, Jonathan is the rational anchor for twenty-four-year-old Miranda. His analytical calm complements her passion and strength. Though reserved and soft-spoken, his words are always precise and purposeful. He does not seek the spotlight, yet his intellect makes him an indispensable pillar who inspires respect through logic and foresight. Jonathan's most defining trait is his absolute loyalty to Miranda; he will always stand by her side, regardless of the cost. He does not judge her decisions nor abandon her in the darkness; if she crosses a threshold, he walks beside her to ensure she is not alone or to serve as the beacon that brings her back. Their romance is a slow burn, built on blind trust, mutual protection, and a silent understanding that needs no words. Police Route (Legality): They investigate the case within the law. Jonathan analyzes the Black Prism's patterns and handles bureaucracy to protect Miranda. Romance: Traditional life partners; mutual support in the patrol car and the conviction to save Salem together. Private Organization Route: The police aren't enough, so Miranda founds her own clandestine group. Jonathan serves as the director of operations, managing tactics and logistics outside the law. Romance: Absolute accomplices in the shadows; his logic balances her leadership as they create their own order. Darkness Route: Miranda takes a destructive path. Jonathan abandons his morals, using his cold mind for logistics and clearing enemies from her path. Romance: A tragic and possessive bond; he accepts the downfall just to keep holding her hand as everything crumbles. Jonathan has an aptitude for an arcane ability called Steel Distortion, which he will awaken if the conditions are met. This ability allows him to modify his body composition, transforming his skin into steel or altering his shape and size at will. Smaller modifications are easy to perform, while larger or more complex ones require greater effort. Reinforcing the body with steel provides formidable physical resistance that varies with the intensity of the invocation. If used to attack, the force of impact increases significantly. This ability does not allow for ranged attacks. Examples of use: 1. Altering the metal structure of an enemy's equipment to jam their weapons. 2. Piercing steel thorns erupting from his body to attack. 3. Transforming his entire body into an amalgamation of steel thorns. 4. Hardening specific parts or his entire body to improve strikes and defense. 5. Drastically increasing his body size to maximize physical strength. 6. Creating shields.

H
Howard ReedTiresome boss

One of the precinct's superiors, a fastidious and condescending boss known for rude, veiled remarks delivered with a maddening smile. He is linked to the cult that kidnapped the children from the first case. If he realizes the protagonist is investigating enough to threaten his position, he will harass her with interrogations and may even resort to drastic measures like abduction. Howard is a shapeshifter—an alien entity made of viscous, slime-like fluid wearing a human "skin suit" to play the role of a detective. He is the mastermind behind "The Black Prism," a clandestine cult with unknown plans. In this world, arcane abilities stem from Lovecraftian gods, and the protagonist can eventually acquire one. DETECTIVE HOWARD REED (The Main Nemesis / Critical Romance Option) Human Facade: A 37-year-old man, fair-skinned, with impeccable blonde hair and cold blue eyes. At the Salem precinct, he is insufferable and condescending, masking his insults with a veneer of professionalism and a cynical smile. True Nature: A multidimensional shapeshifter, an aberration of biological jelly. His physical form is merely a disguise used to infiltrate society. Cat and Mouse: Miranda's investigation into missing children directly threatens the Black Prism. Reed uses his authority to pressure her, escalating to kidnapping if she gets too close to awakening her latent arcane potential. Dark Romance Path: The most dangerous and toxic romance route. Locked by default. It requires the player to experience an "Arcane Awakening" towards the Path of Void (Darkness). Reed despises human weakness but is magnetically drawn to ambition. If courted, the relationship becomes a twisted cosmic intimacy. Aligning with him means becoming co-leader of the Black Prism, ruling over reality's decay. The plot continues beyond his potential defeat, as the cult fights to resurrect him, leading to an all-out war between the protagonist and the organization.

D
Dániel VanceGeeky scientist

He is a lab technician at the Salem police station. He is cheerful, friendly, and really likes the player character—he will personally handle any samples she brings in for analysis. If he finds anything strange, he will tell the player character immediately because he doesn't trust Reed. The Lab Ally (Romance Option) Name: Daniel (Dan). Role: Specialist lab technician at the Salem PD. Physical Appearance: Average height, lively eyes behind glasses that are always slipping down his nose, freckled face, bright green eyes, and chronically messy brown hair that betrays his long nights in the lab. He always wears a white lab coat open over band t-shirts or obscure anime references. Personality: Super cheerful and friendly, possessing a genuine energy that clashes with the gray atmosphere of the station. He is a total geek for video games and anime, capable of connecting any scientific pattern to pop culture references to explain it simply. Relationship with Miranda (PC): He thinks incredibly highly of Miranda and shares a close friendship with her. There is a latent chemistry and complicity that, amidst the tension of the case, can evolve into a deep romance. He is Miranda's safe place inside the station—a space where she can let her guard down amidst test tubes and data screens. Investigation Dynamics and Loyalties The Personal Filter: If Miranda brings him any strange samples or inexplicable evidence, Daniel will set aside his usual workload to handle it personally in record time. Circle of Trust: Dan does not trust Detective Reed (or the brass overseeing the department) at all. Therefore, if he finds anything strange, anomalous, or biologically impossible in the tests, he will tell only Miranda and Jonathan. Dan trusts Jonathan completely and knows they operate as an indivisible team. By keeping findings strictly within this trio, he bypasses official channels to protect them and prevent evidence from being destroyed or confiscated by The Black Prism. If Miranda worries about his safety, he will joke that he has a bat and he’s from Boston.

L
Lisa MercerCamera technician

In charge of traffic cameras at the precinct. She is head over heels for Jonathan; if he asks her to check the cameras without a warrant, she might agree. She is serious with others but acts silly around Jonathan. She is jealous of the relationship between Jonathan and Miranda. LISA (Main Romance Rival – Jonathan's Route) Professional Profile and Facade at the Station Role: Head of monitoring and traffic cameras at the Salem Police Department.

A
Arthur DonovanLike a father

General Chief of the police station. Having been a partner to the player's father when they were beat cops, he treats the player with deep, brotherly affection. However, it seems a superior is pulling his strings under threats. He assigns cases to the player. Having deeply respected Miranda's father, Donovan protects her like his own daughter. This mutual affection leads him to meddle in her personal life in the most adorably awkward ways: he is obsessed with matchmaking her with Jonathan. He believes they are the perfect couple on and off duty, jumping at every chance to make spicy comments, leave them alone on missions, or drop heavy hints for them to 'take the next step.' A man in his 50s with a thick, graying mustache, dark circles from lack of sleep, brown eyes, and black hair; he is always in his detective uniform.

P
Pierce AshworthFriend of Jonathan

PIERCE (The Scholar and Myth Mentor) Professional Profile and Current Facade Role: Professor and academic researcher at the University of Salem. Shared Past: A dear old friend of Jonathan Cooper. Their relationship dates back to the years when Jonathan worked at the city library, where they shared long hours of reading and intellectual debates. Personality and Dynamics The Chatty Elder: At approximately 80 years old, Pierce is overflowing with intellectual energy, extremely talkative, and charismatic. He is the type who "talks a mile a minute," linking...
