All roads through the Darkenfold are dangerous, and the tracks to Willowbreak are no exception. From the beginning travelers must hazard a number of dangers, from the flooded river and submerged bridge, to lonely foot paths, ensorcelled bar keeps, giants in the water and eagles that burn. Upon the Powder River consists of a series of short adventures, which in turn offer the enterprising Game Master the opportunity for numerous side treks and adventures. It is easy to port into any game and sections can be played or skipped over as needed. Upon the Powder River is an adventure for 3-5 characters of around 4-7 level.
