Is it okay to post my current outline in this thread? I've mostly been brainstorming on tying things together. The basic plot is that long ago a witch hunter is rumored to have buried treasure in a mountain temple near the town. There was recently an earthquake in the area, with a strange cloud forming over the mountain. People are interpreting this as a sign that the treasure has been revealed and several parties have ventured up the mountain but not returned. The players arrive in town just as multiple expeditions are setting up the mountain and may get roped into helping one of the groups or set up themselves. This results in a race to see who can find the treasure first as the players journey through dark woods and up the treacherous mountain. Who are these other parties and what do they want with the treasure? What secrets do they hide? Play to find out!
I can post the outlined encounters if people want.
