From the introduction: A local druid tells your party of an unnatural pall of smoke that has appeared at a lonely, rocky point on the coast nearby. The druid suspects powerful magic, and fears that the delicate balance of nature has been upset. He offers to loan the PCs his small rowboat for use in investigating, and to give them two specially brewed potions as a reward when they return.
