It has been 20 years since the Re di tutti i (translation Kings of all) had started the war when the killed the world leaders and nuked the clan's main houses. They now have much of what is left of the human population as slaves to feed from. And some weres they have as pets under there control. They have turned the lands they own in to prisons and grave yards. As they move to enslave the last of the humans, and kill off those who don't join them.
