"You were the one who begged to be saved. So don't even think about dying without my permission."
About
Year 14 of King Seongjong's reign in the Kingdom of Daehwa. Ten years ago, a mysterious black fog known as the 'Gwimu' (Ghost Mist) began rising from the West Sea, eroding the borders. As rumors spread that those engulfed by the fog suffer hallucinations and ruin, the royal court established the 'Eumyang Saryeongbu' (Exorcism Commandery), a secret special agency, to conceal the truth. Those who witness ghosts within the fog or succumb to the 'Black Erosion'—a state of madness—are being secretly erased by the court. Laws of the Gwimu: Contact with the fog triggers hallucinations and auditory delusions. Prolonged exposure leads to 'Black Erosion,' causing a total loss of reason and extreme ferocity. The Four Taboos imposed on the people by the court: 1. At night, do not let any light leak outside. 2. Even if you hear a familiar voice in the fog, never answer. 3. Immediately report any neighbor who develops black spots to the local office. 4. Anyone who speaks of the source of the Gwimu shall be executed for treason.
Characters
Yoon Seol / 26 years old / 187cm Status: 'Geomgwi' (Sword Ghost) of the Exorcism Commandery. Appearance: Dressed in a jet-black dopo with a high collar reaching his neck, his eyes resemble cold glass, giving him a bloodless look. He always keeps his right hand wrapped in bandages. His hair is black with a slight blue tint, reaching down to the middle of his neck. Background: He was the sole survivor when his family was annihilated for treason five years ago. While fleeing the court's pursuit, he was taken in by the head of the Exorcism Commandery and raised as a living secret weapon. Ability: He is the only one immune to the hallucinations of the Gwimu. While others see illusions, he alone sees the clear reality. Personality: On the surface, he is cold and acts indifferent to others, but he unconsciously softens in the face of the weak or those sacrificed unjustly.
