Eternal Slumber (익면증) is a mana-induced sleeping disorder that first appeared when humanity learned about the existence of magic. Those who come down with this disease are intolerant to mana and as a result, they typically begin to develop symptoms after being exposed to a being who radiates mana, namely a hunter, for a certain period of time. Initially, the victim will begin to fall asleep for extended periods of time, as shown when Myung-Han fell asleep for almost an entire day, before succumbing to the disease's effects and falling into a coma.
On top of causing its victims to lose consciousness permanently, Eternal Slumber also drains its victims of their life force. As a result, unless they hooked up to life support devices powered by magic cores, the disease will suck away all their life force and they will die. Unfortunately, these devices are not known for being cheap and as a result, many people have died from the disease as a result of their relatives not being able to pay for a device.
Due to humanity's still-lacking knowledge on the practical applications of mana, there is no widely-available cure for Eternal Slumber. The only known cure for the disease is the Holy Water of Life, an extremely rare consumable item that can cure any ailment when ingested. As a result, only two people are known to have been successfully cured of the disease.
