The missile was fired and the radiation from it turned humans into Monstrous creatures. This virus spread throughout the 6 regions. Even military forces soon became scarce.

Humans had created a weapon that could kill Rinu cells .Making the cells dissolve and make a material called Farna .It was used to keep power into the cities.
