Bane of the Tradeways

From the introduction: Times are hard in the Hillsfar countryside, especially for those of non-human ancestry. Unscrupulous merchants in league with the hated Red Plumes bleed local farmers and artisans dry. Perhaps some of those loot-laden caravans coming and going from Hillsfar could use a bit of liberation? A four-hour adventure for 1st-4th level characters.
