Each hexagon is dominated by a certain terrain. This terrain can range from volcanoes to grassland to forest. The terrain affects the speed with which a unit can move through the hexagon, which races are likely to be found there, and other factors as well. There are many different roads and trails across the map. Roadways may be thought of as running from the center of one hexagon, to the center of an adjacent hexagon, and do on.
Roadways affect movement only between hexagons so connected.
Many rivers and streams flow through the Savage Frontier. They may be thought of as running between hexagons, along the edges that separate them. A unit traveling on a bridge is subject to both the effects of the waterway and the roadway.
