From the Front Cover:
A storm of unparalleled fury has been ravaging the peaks of the Earthspur Mountains for a tenday, and the Monastery of the Yellow Rose sits in its eye for now. Some monks have fled the monastery to the safety of Mulmaster and beseech you to convince their more obstinate brothers to retreat to the city before the eye of the storm shifts, and the monastery is in terrible danger. Can you brave the elements and convince the monks to escape? An eight-hour adventure for 5th-10th level characters.
