...and I'm going to fucking give it to them. (Note: This submission is largely so I don't forget the details of this plan once I'm less pissed off.)

My take on Dracula for my 1640's Demon Hunting Game
PCs camp for the night in a dry pine forest. Fire skill of the person that made it is usually pretty good, but during the first watch the unexpected happens: a spark lights the surrounding woods and a brush fire quickly starts. Be quick or it could turn into a disaster that could affect the entire region.
