The Dalgyal-gwisin is a ghost whose face is smooth as an egg, with no eyes, nose, or mouth at all. The terror erupts when a seemingly ordinary person turns around to reveal a face with nothing on it.
Its core is the total erasure of the features that mark identity, placing it in the same faceless-horror lineage as Japan’s Noppera-bo. The belief that seeing it spreads it makes the gaze itself the channel of contagion.
