As far as I understood it, the captured ones are in effect slaves - imprisoned in their drying heads (decomposing would be too unpleasant ;) ), suffering in torment until they are thrown at something and break... becoming incorporeal, at which point I would assume they would be quite angry, and attack anything at hand (except for the Headsman, who they greatly fear). What happens to the ghosts, when they serve their immediate purpose? Will they descend into the underworld, or just be left behind, roaming and being a danger to the Living? Or will they be allowed into normal afterlife, after this torment?
While I am not sure I would use The Headsman as an NPC, it has that distinct boogeyman quality, that makes for a thrilling dark tale at the fire, and a moral as well - the worst of the worst will be met by the Headsman.
On improving him, perhaps he remembers his former service with sadness, and may stop for a moment at an altar of his religion (just find out which it is!), or may be partial to exchange a word or two with people carrying a certain symbol. Of course this does not prevent him from judging, he will never give up, and continue until his terrible work is done.
A question, though, on the nature of his judging, while he is on the way to the guilty: does he simply cut down anyone he meets, or does he choose, and leaves some alive (or only the truly innocent... which would be very few)? Go to Comment
