The lake monster is only attacking the Bremen fishing parties. There are various stories about the creature, all of which do not collaborate each other.
Tali, a half-elf researcher, informs the group of the monster, though is interested more in why the monster is here, but not to kill it. They give the party a notebook to record any details about the creature.
Is this a Plesiosaurus? A human, named Ravisin gave the Plesiosaurus the ability to speak. She has been told by Ravisin to attack the people of Bremen. Ravisin is a druid with long hair to the floor. This is the only description that the creature can give.
The creature agrees that if the Bremen's extend a sign of friendship when they meet the creature, it will stop attacking them. The party tell the fishermen about this.
