There was nothing there were I went. It was into the clouds. We had to share the sky with all of man's flying machines. I'm ghost with my human body. So I'm called a ghoul.
It might sound like we are evil creatures who eat people. But that is not it. We are the invisible, forgotten, and dead. As such we have to follow the rules of the dead. No bothering angles, stay out of everyones way and be not seen or heard by anyone. If you are seen you are made permutably invisible. If heard you can no longer speak. None of these things are needed to survive and communicate. But it dose take away the fun of things.
The ghosts can't speak, can make sounds to communicate and scare people at night. They have no body to protect. The damage is terminate, nothing to do. You have to live your days out in a broken body. Those days end when the last of your relatives die. Then your end is chosen by the same test as everyone else. The one where you go to heaven or hell. No one tells you about the in between.
Where the spirits are created.
