The cloud doesnt have much of a smell. It looks like fog until it’s on you and then it’s two late. A couple of sucking breaths and your chest is one fire and your eyes are bleeding. Terrible stuff, but if you think it is tough on the living, you should see what it does to the dead

There is a group that believes no good can come of trying to change to future to render a prophecy or prediction incorrect. They believe that meddling will either cause the prediction to be true in the first place, or make something worse or more extreme happen.
