“ A casual remark by one of the party about something met on a previous adventure leads to a summons to and grilling by the Mages' Guild (or equivalent), probably resulting in an expedition back to that area to recover the things for study by the Guild. The party's presence will be 'requested' for this expedition.”
“ There are reports of a monster that lurks in the tops of trees and drops down on unsuspecting people. It causes them no damage but it frightens them with a hide-like face with big dead eyes, drooling and barking like a dog while unsuccessfully attempting to have intercourse. The PCs investigate and find that it is the local village moron that is doing the spelunking in the woods. How can they explain this otherwise pleasant and merry man that it is wrong to put on a mask, drop down from trees and attempt intercourse with relatives and neighbours.”
“ The Orcish Mustang - a semi-wild horse tamed and domesticated by orcs to serve as their mounts. Large, strong bodied, and fearless as they live among orcs. On the other hand, bad tempered, with teeth problems, sometimes have hoof problems, and agressive. In lean times, or when an animal dies, the orcs suddenly have a dearth of meat, and hide to work with.”
