Right before or right after the end of WWIII which I am not clear, three days of darkness will take place as God will finish cleaning up the earth from its evil inhabitants. For 72 hours, hell will be unlocked and empty of all demons. Devils spirits will be allowed to carry away people alive. All man-made structures, cities, buildings, factories, etc. which are not occupied by the blessed ones will be burned down or destroyed. “The earth is thrown from its course and the sun won't give her no longer any shine. Darkness will be on the whole globe seventy-two hours long. During this darkness no light will burn, except the light of the faith and sacred candles, which is preserved to everyone, who fulfilled loyally the request of the God Mother. The true Christians will close and cover windows and doors during this time and assemble around the cross and the picture of the most Blessed Virgin, in order to pray. ... Do not look out of the window and do not be curious, what is going on outside, otherwise you have to die!"
"Darkness for three days and nights. Beginning with a terrible thunderstrike with earthquakes.No fire burns. One can neither eat nor sleep, but only pray. ...Lightning penetrates into the houses, terrible curses of devils are to be heard. They will imitate the voices of your loved ones asking to come inside. Earthquake, thunder, sea noise. Who looks curiously out of the window, will die immediately. Admire the precious blood of Jesus and call Maria. The devils take the Godless ones in live bodies. These ones ask in vain for an extension of their life." "The plague rules, large black marks can be seen on the arms. Sulfur steams fill everything, as if the whole of hell has been released.A cross appears in the sky. This is the end of the darkness.The earth is a corpse field like a desert. Humans come out quitely, frightened from their houses. The corpses are collected on waggons and buried in mass graves. Neither railways nor ships function, nor cars as in earlier times. The factories do not work, the fast pace of former times has stopped."
"...During the war the big darkness comes, which lasts 72 hours." "It will become dark at a day during the war. Then a hail impact, consting of lightning and thunder, breaks out and an earthquake vibrates the earth. Please do not go out of the house at that time. The lights do not burn, except candle light, the current stops. Who inhales the dust, gets a cramp and dies. Do not open the windows, cover it completely with black paper. All open-standing water become poisonous and also all open-standing meals, which are not in locked doses. Also no meals in glasses, because they would not cover it up completely. Outside the death by dust goes around, many humans die. After 72 hours everything is over. But again: Do not go out of the house, do not look out of the windows, and keep the candle light burning. And pray. Overnight there will die more humans than in the two world wars before."
-"The year 1999 will bring destruction, followed by peace. A darkness of 72 hours will precede peace. The time of the year may be autumn, for there will be snow on the mountains, but not yet in the lowlands. The sign if the Cross will appear in the heavens. The war will end as quickly as it began, and a natural phenomenon will end it. The last battle will be near Cologne, and it will be won by the West...”
-No more modern lifestyle with its conveniences will exist after three days of darkness.
-Whole nations will vanish. Two-thirds of mankind will be abandoned by God.
-Thus, when you see the WW III coming to an end, be prepared for three days of darkness, gather your children and grand children, tape your windows shut, lock your doors, hang the crucifix or blessed objects by doors and windows, have one blessed candel and matches ready (electric or battery-run items will be useless.) You might need ear-plugs, little food and water even I do not think you can eat or drink any. When the sun rises and the demonic howling and thunder stops, you can come out of your house and it will feel like spring-time as everything will be renewed. However, you might have to move away from your house because dead burned bodies will be everywhere. Surrounded you will be dead bodies, burned buildings and houses but consider yourself blessed to be alive.
-Life eventually will return to normal but you have to work with bare hands and rely on the land to live as there will be no more modern conveniences, science, or industries. There will abundance of rich land to live on as the earth will be completely void of its evil inhabitants. Some blessed ones will die also but they will return to God. Some non-catholics who can be converted later will be protected also. Only ones who are devoted to Our Lord and blessed Mother will have the best chance to survive. The Rosary will save you.

May God Bless you.
