The Horn of Plenty

Publisher's blurb: This fourth-level adventure is designed to work with the free basic rules offered by Wizards of the Coast. ... When a powerful magic item is stolen from a wealthy farming association, the leaders turn to a band of reliable and - most importantly - discrete adventurers to retrieve it. Their journey takes them into a cave system filled with sickness and rot, and thrusts them into a debate over applying magical solutions to practical problems. Where will their loyalties fall when forced to make a tough choice?
