The Isles of Vecta or Wict

On 26th September 1983 the Soviet Union early warning system falsely detected the launch of multiple  intercontinental ballistic missiles from bases in the United States. The Soviets immediately retaliated to what they thought was a US first strike nuclear attack. Within 12 hours over 60,000 thermonuclear weapons had been detonated destroying all of the world’s population centres. Within a year only a few thousand humans remained.

Many years of drastic global cooling and warming cycles followed. Sea levels rose then fell. Over the centuries traces of pre-war human structures, science and culture almost disappeared. However the few human survivors gradually began to establish small communities, mostly on isolated Islands. Primitive civilisation started to re-emerge and a thousand years after the war a map of one of these Islands was printed.
