Before this, Before the demons everything was as fine as daisy's well that's a lie. We had war's, virus, and famine. We cared only for ourselves and forgot that our action's can affect others. We were selfish, and now we have no choice but to try and stick together, hide and see if we can even survive this.
Lilith, War and Death are all together, taking children as hosts for new demons, making the men and women fuck and fight until they are satisfied. Even with the knowledge of what they are doing we can't stop them, people have already tried to rebel but nothing ever came of it except bodies being dragged around by shadows shaped like dogs.
There are many rebellions going on at this current time but no one has go to the demons and horsemen themselves, they are killing off the lowly demons that go through the gate with them.
Famine and Pestilence are in Russia, killing crops and spreading disease killing people slowly, no one can keep up but they are trying. They are fighting for their right to live, famine and pestilence are so slow that people may be able to survive there a while and possibly escape but that is hopeful thinking.
Rogue is in Greenland just slaughtering everyone she see's luckily people have caught on to this and have started to hide away to escape her sword, but its only a matter of time before she finds them once again.
The rest we do not know where they will turn up or how many more will appear. I hope for everyone's sake that it's just theses. The four horseman of the apocalypse, Lilith and Rogue. But once again that's hopeful thinking.
