Dry Spell

From the publisher's website:

An unusually severe drought in a remote area recently worsened dramatically when three lakes dried up almost simultaneously. The locals suspect foul play, and the foulest player they know is a bugbear named Relgore -- the leader of a highly successful group of humanoid bandits. Could he be seeking revenge for the militia attacks that recently dispersed his band? Check out the latest miniadventure for D&D v3.5 by Darrin Drader.
