so i accessed the feature by spam jumping on a tilted building, scaling the wall to the top. It was a gray building with 2 rainbow things coming out of it. (Best description i got)Then I jumped off on top of a hill and walked as far as possible until all the mist disappeared. Maybe you could do a jump scare and death when walking towards the edge of the map, I was shitting my pants when walking because it felt like something would jump me.
