Bound By Duty

From the introduction: Civil disorder threatens to throw the leaderless town of Ylraphon into chaos. You find respite from this political strife when the Chiang Emporium hires you for an escort mission. The task: sail south to accompany a Chiang Emporium envoy on a return voyage to Ylraphon, where her wedding is to take place upon her arrival. The voyage is perilous, but not nearly as complicated as what awaits when you finally make it back to town. A 4-hour adventure for 5th-10th level characters (optimized for 8th level)
