That would be an interesting idea! However, we'll have to see what everyone else says. Some people may find the plot a bit too complicated to have so many characters in.
I'm back! Okay I'm coming up with a random plot as I type so here I go! When you die, what do you expect? Anyone would expect that you'll go to a safe haven in the sky or go to place below our feet. Reality check! It isn't like that. Our government is corrupt as it is but what if a secret is unfolded before us? When you die you leave behind an essense that can be captured and used to hijack another person's body. What if that essense and the controlled person are used as weapons? What would happen? World domination? Apocalypse? What would happen if a band of people were strong enough to resist any essence thrown at them? What if those people started a war and became our saviors? But what would happen if they lost... I'm not sure where that plot is going...
