You have explained most of the literary questions very well: Who? What? Where? When? and How?
My only remaining question is "Why?"
Why? Because it’s fun. Because we like each other. Because everyone can play here as long as they follow the simple rules. Because when you show up on the Undead Thread and go “AAAARRRRRRRGH!” eventually somebody will come by and say, “Now, now dear. Have a Guinness and hug a kitten.”
