Chernobyl before the accident that made the region inhabitable (some members of the Ukranian Communist Party could made a failed reopening of the powerplant)
In a turn of events that surprised no officials at Fastiv when they finally heard about it from the few survivors, who themselves died of radiation poisoning shortly afterwards, something - to this day the area remains too radiated to find out - horrible had apparently happened at the plant, and some sort of meltdown had occurred. The net result was many deaths, and the irradiation of much of the Pripet marshes.
