Over a century and a half ago, the gods got into a quarrel. We don't have all the answers as to exactly what was going on; all we know is that roughly 80% of the world's population was killed in the process.

We call the event '77. Despite it being over and done, the world still faces the aftermath today. Political extremists have taken the opportunity to claw their way into positions of power.
The world's problems are far from over.
