They went hunting for the Lake monster! The knew where the children were being held, but decided to look into the lake monster for the heck of it XD. So, despite the strong protests from the party Fighter, ("Look how big that tooth is!!!!") they went out in the midde of night on a very dark and foggy night in 3 boats. After sitting around for a while, the Figher (also an elf), hears something swimming up from beneath one of the other boats. He tries to warn the other boat, but alas, it is too late. The montser breaks through the boat the other character (who was by far the most powerful and overpowered PC in the party) was in, bites him for almost instantly lethal damage (he was at -3 hp), and drags him down into the depths. The other PC's promptly row back to shore. Because of their actions, the lake has been closed to all activity, are down their most powerful party member, and they were given gold by Vhalantru in compensation for their loss and the warning about the presence of the monster that their comrades death has given them. Until that session, I did not know the infinite limit of PC stupidity. What do you guys think?
