A new take on hell that leaves you gasping on the edge of panic.
A beautiful, broken land tended by feudal families. Densely forested, this land holds many mysteries in the areas not cleared, and some mysteries are dangerous.
There lies a valley, far to the west, on the shores of The Great Northern Sea, that has a mist that is both blessing and curse. All those that breath the mist heal with remarkable speed, so fast that only the mightiest blow or the truest strike can fell the smallest beast. The warriors who settled this land became soilders of great renown, for not only were they impenetrable defenders, they were warriors whose aim and might were unsurpassed.
A plague has hit the local area.
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.
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.
Somebody (enter the PCs) must find the rare herbs needed to make a cure.
