The following table, inspired by those found in many classic modules, details an example of rumours that might be heard in any large city; though I had it in mind for the area around Upaplavya, in the Matsya kingdom (a good relatively peaceful minor kingdom in which to start a campaign).  Any of these rumours can serve as a potential adventure seed.
