I have a story in mind which is something along the lines of the Christian apocalypse. Replacing the horsemen are four demons that each control one of humanities darker emotions. They are Fear, Pain, Hatred and Ruin. Each one more powerful than its predecessor but they will not be the main characters of the story. It will be more centred around humans fighting back in vain. I intend for this story to end with the world in ruins and humanity wiped out so I have made the four demons far superior to anything the remnants of humanity can muster though I have questioned whether this is wise. Should they have some weakness to allow the humans a glimmer of hope?
