The apocalypse did not arrive without warning. For three days, the whole world remained overcast, but no one connected the dots. On the fourth day, the entire city, country, and planet were suddenly shrouded in white mist. Humans and animals alike passed out, while only the plants grew wildly once more. When the white mist receded, everything seemed to have returned to ancient times. The dead came back to life, and plants and animals instantly rose to the top of the food chain. With water and power cut off, the technologies people relied on to survive seemed insignificant in the face of these powerful forces.
