A plague has hit the local area.<br />
In humans it affects only the most vulnerable, the children and the very old, and even than it's little more than a summer cold. 24 hours of sniffles and then it's gone, barely noticeable really.<br />
To sheep however it is fatal and the whole economy of the area is in serious trouble. If this keeps up the area could well be facing famine.<br />
Somebody (enter the PCs) must find the rare herbs needed to make a cure.”
