Terror in Shadowcliff Vale

From the introduction: The [characters] are on the road through Shadowcliff Vale when they meet a traveler leaving the village. He tells them that nothing has been heard from the lord of Shadowcliff or anyone else from the castle in over a week, nor have the gates even been opened in that time. The villagers are worried, and both the goblins of the forest and wild beasts have begun venturing closer and closer to the village. He suggests that they use caution if they continue toward the village, and to stop at the tavern if they wish to learn further.
