I had run it in Chapel Hill for my group down there right before I left as a two-night game, so it would have had to have been rewritten for the Game Day. Basically, a small village in the Connecticut River Valley has lost contact with the colonial leaders in the eastern part of the state. A small group is sent out to find out what's wrong. From there, it's cultists and terrible things that man wasn't meant to encounter.
When I ran it the first time, it had some moments that didn't come off the way I wanted them to, but it also had some truly creepy moments — one of the characters that my group created was a Puritan minister with some psychic powers, and he ended up having some nasty visions (my favorite was a dissociative moment where he envisioned modern Massachusetts with all its trappings), and there was also an encounter with some colonists hunting witches/referencing the Salem Witch Trials, which was still a long time off during KP's War. I was using these to underline the wrongness of what was going on in the village and how it influenced the area around them (it was like a taint...the closer you got, the stranger things were).
Given a few weeks and a chance to rewrite/modify it, I'd be happy to run it as a play-by-post if you did want to play it. Naturally, the visions and what not that I've described above wouldn't be in it, but there's plenty of colonial history to mine for fun things.
