Lochfell's Secret (3.5e)
Stories of misfortune are often exaggerated¸ especially when they have been retold many times. For that reason¸ most people aren't taking seriously the claim that a sea monster living along the coast is eating whole ships full of sailors and swallowing entire families. But there's no denying a few facts - the town of Lochfell is losing its citizens to a sea monster (one that walks on water no less)¸ someone is stealing that same town's dead¸ and ships are beginning to choose other ports for unloading their goods. Such a scenario could doom the residents of the small port town to either a monster's gullet or the poorhouse.
"No one seems to know whether the town's two ongoing problems are connected¸ but the sea monster never leaves behind a corpse to bury. Is it collecting bodies for some dark purpose? Or did some more powerful evil creature create the sea monster to do its dirty work?
"Someone in Lochfell knows the answer¸ and it's up to the PCs to find it out.
