The terrain through which a character travels affects how much distance he or she can cover in an hour or a day (see table below). A highway is a straight, major, paved road. A road is typically a dirt track. A trail is like a road, except that it allows only single-file travel and does not benefit a party traveling with vehicles. Trackless terrain is a wild area with no paths.
