When the party arrive in Easthaven, they discover that the wizard, Dizan, is being burned alive that evening. They do what they can to speak to him, but he is incinerated.
In the city, the captain of the guard, Imdra Arlaggath, tries to get the party to go out onto the lake to find some fishermen that have gone missing, but the party decide not to do it. At the seance, the party discover that the fishermen are in Maud Chiselbone's cauldron.
The party go out and find the fisherman's boat and footprints heading into some caves. They naturally follow the footprints.
It turns out that the human fishermen were killed by an undead frost giant that haunted the cave and cooked by a Lake Hag. The party kills the giant and encounters the Lake Hag who they make a deal with. The Hag gives the party her magic couldron and promises them the chest from under the lake. They must leave an hour before midnight and travel North for an hour.
They return to town to claim their prize.
