This Tweak & Toss "adventure" is a rather simple set-up/problem for the party to deal with. The design is deliberately vague in several areas to make it easy to integrate with your current campaign. Perfect for when the party goes "left" when you expected them to go "right", any GM/DM/Judge can easily drop this into the current campaign.
The idea behind this Tweak & Toss is that the local region has experience some sort of tremor or earthquake. A group of traders has not been able to rendevouz with their Dwarven & Elven counterparts and would like the party to track them down.
