Build Yourself up. Sovereignty is within your grasp!

The first story only Uses my own Characters. Not a fan-fiction. the story will have evolution qualities for humans and creatures as well as the environment. The other two fan fiction I have will be smashed into this one. World has gone haywire. Creatures of horror rule micro-universes. Humankind has shrunk down to small levels. The main character wakes up from a coma in a world no longer like his own. What to do?
