A dark cloud, 300 to 400 meters high, pitch black, will come from the north-northeast across the world. It will be so dense that no light penetrates. Unlike earlier seers who described three days of darkness, the Stuttgarter Seer warns it may last longer — weeks even — because fine mineral dust and particulate will not settle quickly. Those who inhale the dust in the open will die. Homes must be sealed; blessed candles must be lit.
