The end-piece helped this story. Me? I found .....the parson who exchanged his soul for that of the local tinker a nasty character. He went off to do whatever missionary work he likes... apparently without a care of the world. I suspect that bastard’s final fate isn’t set yet. If Satan {the dude with the sword at the waterfall} is so easy with his broken promises, the preacher gets his reserved-spot-in-hell in the end.
The story had a Dante’s Inferno vibe to it.
And no. It has NOTHING to do with the movie-musical, Grease. :)
