Quest:Ow! My knee.

Upon rescuing the wife in Help! my house is on fire! she reveals that she has hurt her knee and asks if they could go to the local herbalist/medicine man and get her something to make sure it doesn't get infected.

The herbalist knows just the thing but hasn't got any at the moment and asks the player to fetch them some.

The player will be rewarded when they return with the herbs and not a moment before.
