Dragonne
A/several dragonne {There are enough that violence should look unwise, tho not unthinkable.} has a herd of unusual goats. The dragonnes apparently just deem them food, but somebody else thinks they have a much better use and wants to cut a deal with the monster, offering more of more common goats or a steady supply of free meat, or... Of course, direct dealing with a creature known to eat people is not for the faint of heart and the party is hired to deal with the situation.
The party will have to bargain with creatures who will have a rather dim view of the idea and avoiding trouble should be difficult. But any good idea that can be shown to benefit the dragonnes should be possible. [Since dragonne are IQ6 and wis12, they may be easily conned by the right pitch, but will catch the party if the pitch is just a bit different. In any case, if the party does get away with something, they had best stay out of the area thereafter.]
