Talk to Malene; a monster stole a parcel she was expecting and she asks you to find it for her. The problem is that monster who stole it is hiding near the lighthouse and won't come out. She mentions another adventurer named Dalzakk who might know how to lure the monster out. Dalzakk lives in a house on Kulatz Bridge.
(Optional) Go to Dalzakk's house, he isn't home so talk to Gwill. Gwill gives you the hint about the monster, put a quus behind the lighthouse.
