Holes of Narrowsend

From Introduction: In Holes of Narrowsend, the party is in mid trek over high terrain and descends a mountain into a peaceful looking village. But appearances can be deceptive and the PCs have stumbled into a war between the poor villagers and a band of rampaging bugbears, which has moved into the sacred holes of Narrowsend on the mountain overlooking the village. Can the player characters free the folk of Narrowsend, or will the wrath of the peasants' goddess bring death to all?
