Hmm, that certainly would have been a cool way to go. I limited myself however to PCs that spoke up about wanting me to start with them and unclaimed NPS regions as those are the permissible starting regions for nomads, so I ended up choosing an underground location with the logic that that way it's somewhat less overly dramatic, somewhat more mysterious, and they could then still have come from pretty much anywhere. Conveniently enough as raindragon pointed out there is an unexplored underground region just two regions away meaning that if they didn't come from somewhere thematically dramatic they could even have been sleeping there. Alas, raindragon's already typed up half of his IC reply so I'll stick with where I'm at. Still, thanks for the thought and time you've put into this list for me. Indeed I do very much hope that the witches will soon visit all of these locations.
