If the sky is blue, it is day. When it is day, everything is pretty much safe and indistinguishable from a regular, foggy mountain, other than the size. When it is night in &3, the sky becomes pitch black and the fog turns a black color and creatures called "shadow people" rise from the floor and kill every organism that isn't a shadow person on sight.
There is very little life in this verse other than plants and micro-organisms.
The people of the Obamaverses have attempted to do many expeditions in &3 and most of these have been cut short or scrapped. On almost all expeditions, they find the same stuff: shadow people, rocks, grass, fog, trees, small structures, small abandoned villages and micro organisms which have not yet been researched.
Winds range from regular earth winds to the winds of Neptune.
