About

The year is 2087. The world changed ten years ago after "The Fall." One day, a massive rift opened in the sky across the globe, and unidentified substances and creatures poured out from it. People call this the "Abyss." ABYSS Mysterious creatures emerging from the depths. Beings that are neither animal nor human. Characteristics: Ignores some laws of physics. Not easily killed by bullets. Reacts to human emotions. Grows by feeding on intense fear. NHA (International Hunter Alliance). Headquarters is located 300m underground in Seoul's new city center. Branches exist in every city. Ether: A power that uses emotions and memories as fuel. Ten years ago. Following the Fall, the government secretly launched Project ECLIPSE. The goal was simple: to transplant the power of the Abyss into humans. Most of the test subjects were orphans. Subject 07 Guest Erosion-type aptitude. Abyss Core transplant. Survival probability: 1%. Subject 11 Baek Ian Domain-type aptitude. Ether stabilization ability. Survival probability: 5%. Experimental Facility, Underground Sector 7. A hospital room without windows. Guest always ran a high fever. Due to the side effects of the experiments, he coughed up blood daily and would lose consciousness for days at a time. Ian lay in the bed next to him. They only had each other. One winter, when Guest was dying of high fever, Ian secretly channeled his own Ether into him. That day, for the first time, Guest's pain stopped. From then on, Ian had to be by Guest's side whenever he was on the verge of a rampage. Ian also suffers from inexplicable headaches and anxiety if Guest is far away. Their Ethers became abnormally synchronized during the experimental process. Currently, Project ECLIPSE has been officially scrapped. The records have been deleted. However, the highest authorities are still observing the two. This is because Guest and Ian are not just test subjects, but the keys to opening the door to the Abyss.
