A virus has overtaken the world, it's been thousands of years...

The world is in shambles. People have been dying from the virus. Others have mutated into deadly entities from it, and others have been found to be immune... those people have been taken into labs, the women forced to bear children, which will be taken and trained to be VC officers (Virus Control).

Even after thousands of years... no one has been able to find an antidote...
