A building
as you approach the shape reveals itself as a largish building.
You find the door which slides open and you are sucked in along with a bit of the mist before it is closed again.
then you see a circle of light shine underneath you and a computerised voice says "SCANNING... clean... access granted."
Then another door slides opens and you walk through to see a number of what look like radiation suits.
