One day, at the first light of dawn the characters come across a letter about Davanor, a curious wolfkin mariner who wants to seek revenge for a family heirloom known as Wintermoon
The journey is hard and miserable and ends on the bank of a river. There is a strangely shaped castle surrounded by the remains of dead animals. The place is called Melka's Gift
The way in is dangerous - a trap has been set. There is a winding stairway leading down into the darkness but also unexpected guests in the form of 2D8 goblins and a ravenous giant spider. There is a deadly challenge in the form of crushing walls.
