From publisher blurb: Nuvak Highmoor, the guild master of the Dungeonsweepers, approaches the PCs about a possible mission for them. According to local rumors, a small band of Drow have been spotted creeping about the Southwest Sector of Burden’s Peak after nightfall. Nuvak instructs the PCs to post a watch over the Southwest Sector to try and determine the authenticity of these claims.
