" The Troll Patrol was an institution unique to Dun Hythe. Long ago, the city leaders had recognized the need to control and direct the heavy wagon traffic that flowed to and from the port area. They organized a patrol of citizens for this purpose and all went well for a while. No one knows who allowed the first troll to join up, but word immediately spread throughout the troll community that one of their number had a paying job with unlimited donuts. Soon after that, every opening in the patrol attracted dozens of trolls who brazenly persuaded non-trolls to withdraw their applications. Within a few years, trolls had taken over the organization.
Trolls proved to be particularly inept at traffic control. A member of the Troll Patrol could station himself in the middle of a deserted intersection and, within minutes, he would create a traffic-snarling mess. To keep the enraged wagon drivers under control, the trolls relied upon truncheons. A whack or two in the head always knocked a driver groggy and made him a lot less noisy. "
