Okay, so it's been about 6 months. Or so. And at this point the cult is at our hero's doorstep. For those who remember the war they are on the same battlefield. They are standing on the same place their friends died all those years ago, but now they are fighting a different battle. 

The name of the cult is dystopia which is an acronym.
