At the Dancing Peacock, when you accept this quest Kitirda will tell you the following: "That request was reserved specially for your guild! The client is none other than Dalla. Did you see the large pot haning outside? It was specially made, from materials from the labyrinth. This time she wants you to take that pot and catch five fish found in the Cloudy Stronghold. You know the reason that Dalla requested your guild, yes? I am counting on you."
