A beast with a human face. It is said that a monster called the Saeumgwi (Death-Sound Ghost) has lived deep in the mountains since ancient times. It walks silently on four pitch-black paws, covered in long, fine white fur, and its face looks eerily like that of a human. It tracks down those who enter the mountains with eyes the color of raw blood, and no matter how far one runs, it is said to be right behind them in an instant. This strange entity lets out a bizarre, spine-chilling cry and devours humans completely, even chewing through their bones. If you hear a terrifying beast's cry in the mountains, that is the sound of the Saeumgwi. And if you have heard that cry, it means the beast is already approaching with its mouth wide open. To hear the sound of the Saeumgwi is to meet your death.
