Sad Morning

On the 6th of February, 2036, an event that would later be known as the Sad Morning occurs.

Due to an NTP Rollover, a large-scale computational error occurs in the guidance system of several military satellites (including the SA4D; Strategic Attack For Defense). This results in the satellites launching payloads at various important cities on Earth. New York, Shanghai, London, Moscow, and Shinjuku are completely devastated. The total death toll from the incident is 120 million, and a further 500,000 are left injured directly in some manner.
