Boo, ya bastard!

You've been killed, and there's no changing that. Unfortunately for your killer, you've managed to hang onto the mortal world as a ghost. New and clueless as you are to the whole ghost thing, you're not sure what you can do yet, but you're determined to haunt them and make them regret killing you if it's the last thing you do! Which it probably will be, you don't know how long you'll have the resolve to keep yourself from passing on to whatever comes next after death.
