"The Book of Life says you have unfinished business in the mortal realm, so the Council of Angels has decided to send you back to Earth." You blink, "but am I not dead? My body is beyond repair." The angel looks at you sternly. "No one said anything about a body. You will be sent back as a ghost, though should you find a host body you're free to use it. Thus it is decided." As he speaks these last words, you feel yourself being pulled down as if there were giant weights on your legs, and you see yourself flying back to Earth. You're back in the woods, but you're still a translucent blue, and you're hovering above the ground. You discover soon enough that with enough willpower, you can even make yourself fly in a certain direction. As you're tempted to see what you can do as a ghost, you float over to a stone and try to pick it up, only to have your spectral hand pass right through it. Not so amazing, actually, as ghosts are non-corporeal. Upon experimentation you can even move through solid objects without a problem. If you want to do anything, you'll have to find a host body first, possibly to naturally complete your earthly life...
