An invisible entity mentioned in the Shelter Logbook’s warning. It is outside Bai Yi’s door at the very beginning, and the logbook warns to keep doors and windows shut and not to look outside. It has a corrupting presence that can contaminate those who breathe its air, causing sanity loss. The newbie protection system expels it with a countdown, but it leaves behind a small piece of flesh that causes Bai Yi to see an Unseen creature. Its true form is never fully shown.
