A battle-hardened former UDT/SEAL non-commissioned officer defined by cold, calculating pragmatism and an indomitable will. Seventeen years prior, his parents were butchered in a brutal conspiracy; the recent assassination of his aunt drags him back to his ancestral roots in Gwichon Village. Operating under an icy, borderline sociopathic demeanor, Mumyeong combines military-grade counter-intelligence with psychological warfare. He does not merely seek to kill the village conspirators - he systematically dismantles their minds, manipulates their greed using ancestral property deeds, and forces their occult syndicate to cannibalize itself from within. Powers: Master of UDT/SEAL close-quarters combat (CQC), lethal combat knife handling, advanced marksmanship, forensic counter-surveillance, tactical trap-setting, and high-level psychological interrogation. Possesses an iron mental fortitude that grants him natural resistance to fear-inducing spiritual hallucinations.

A world-weary, highly cynical senior detective from the Gangwon Police Department. Assigned to investigate a chain of missing persons and anomalous homicides tracing back to Gwichon Village, Kang San initially views the case through a strictly forensic lens. However, as humanly impossible crime scenes and altered autopsy reports pile up, his rational worldview shatters. Despite intense pressure from corrupt superiors to bury the files, his relentless commitment to justice forces him to confront the supernatural horrors buried in the mountain woods. Powers: Master criminal investigator, expert marksman with standard-issue police revolvers, proficient in hand-to-hand law enforcement restraint techniques, high situational awareness, and sharp deductive reasoning capable of piercing cult deceptions.

The tyrannical, blind patriarch of Gwichon Village who has governed the secluded region since at least 1995. Beneath his veneer of a frail, traditional village elder lies a ruthless occult mastermind who maintains his longevity, wealth, and authority through human sacrifices, illegal real estate land-grabs, and dark shamanic pacts with "The Mother." Paralyzed by the fear of losing his control, he executes outsiders, burns evidence, and sacrifices innocent villagers without hesitation to preserve the settlement's dark covenant. Powers: Mastery of dark shamanic rituals, curse casting via sacrificial vessels, psychological manipulation, absolute socio-political control over Gwichon Village residents, and the ability to channel malevolent spiritual entities to inflict afflictions upon dissenters.

An enigmatic, quiet young woman living in Gwichon Village who finds herself constantly positioned at the boundary between the mortal realm and the supernatural. Possessing innate spiritual sensitivity, Ga-eun is plagued by terrifying visions of vengeful spirits and ancient atrocities. As the village's spiritual wards collapse, she becomes the living anchor through which the tragic history of the village - and the wrath of the entity Maher - is channeled into the physical world. Powers: Latent spiritual mediumship, premonitory visions, resistance to localized hexes, and an intuitive resonance with ancient shamanic talismans (bujeok).

The guilt-ridden son of Village Chief No Seok-dae. As a child, Uju was forced to witness a bedridden youth sacrificed as a substitute offering to secure his family's prosperity and health. This foundational trauma left him deeply alienated from the village's corrupt traditions. In adulthood, Uju seeks atonement for his bloodline's sins by quietly aiding Ga-eun, defying his father’s directives, and leaking critical truths to outside investigators. Powers: Intimate insider knowledge of Gwichon Village’s hidden tunnels, kiln locations, and occult practices; skilled in stealth and evasion; basic survival capabilities.

A heavily scarred, physically imposing brute who serves as the Village Chief’s primary muscle. Seokho manages nighttime village patrols, silences inquisitive outsiders, and destroys forensic evidence of the cult's sacrifices. Cruel and greedy, he is easily provoked and becomes an unwitting pawn in Mumyeong's psychological real-estate schemes. Powers: Heavy physical strength, street brawling, intimidation tactics, proficiency with blunt weapons and hunting tools.

A dependable, highly analytical detective within the Gangwon Police Department working directly under San Kang. Min-guk serves as the practical backbone of the investigation, cross-referencing cold-case missing persons reports, tracking illegal land-deed transfers, and uncovering the financial paper trail left by Gwichon Village's elite. Powers: Advanced forensic analysis, digital cross-referencing, investigative interviewing, standard police firearm handling, and tactical backup support.

The village’s former, revered traditional mudang (shaman) who dedicated her life to appeasing restless mountain spirits and keeping the ancient curses at bay. When the greedy village council votes to fell the sacred Village Guardian Tree, her spiritual link breaks, leading to her sudden, tragic death from supernatural shock. Her demise removes the final barrier protecting Gwichon from total demonic consumption. Powers: Traditional Korean shamanism, ancestral spirit pacification, talisman crafting, ritual exorcism, and spiritual ward maintenance.

The tragic origin point of Gwichon Village’s overarching curse. Decades prior, Soon-ah, a pregnant village woman, was brutally murdered beneath the sacred tree by the village elders to secure dark prosperity and cover up illicit crimes. Reborn as the malevolent psychic entity "Maher" alongside the dread presence of "The Mother," her spirit executes horrific, karmic retribution on all descendants and conspirators tied to the village council. Powers: Demonic possession, biological necrosis, induction of acute visual and auditory hallucinations, telekinetic fire generation leading to spontaneous human combustion, and reality-warping spiritual dread.

An ordinary young supermarket worker in Gwichon Village whose mundane existence is shattered after handling a contaminated occult object linked to the village's 1995 rituals. His rapid physical and mental decay serves as an alarming early warning of the awakening dark forces in the area. Powers: None; ordinary civilian afflicted with acute shamanic skin lesions, severe fever, and supernatural decay.
