Wow pretty cool! Thanks! Please keep 'em coming!
Seems like The Hollows is a popular starting spot. I think it's suggested in the book to start there, isn't it?
So far my favorite idea (not that the others are not good, not at all!) is pellejones' crossroads idea.
Not sure it's "in medias res" enough to my liking, as I like to start a campaign in an action moment to get the hype high right from the get go.
I'd probably start in a short action scene of some sort and then drop then at the crossroads. Maybe something like they are getting chased by a monster or an orc warband or something similar and they stumble at a crossroads and need to quickly decide where they're going. If they are not careful, maybe the monster/threat will track them up to wherever "safe place" they end up.
