Part the Second: TerrainEvery province has a primary terrain, which broadly represents, both, the topography of the province and its general climate. Primary terrain determines the base maximum province level (MPL) and the base growth rate multiplier (GRM) for a given province, as well as the overland movement cost for regiments moving into the same.
Each province may have as many as two types of secondary terrian. Secondary terrain may modify the base MPL and the base GRM of a province, to a limit of that secondary terrains base MPL and GRM figures. When sets of MPL/GRM modifiers from two types of secondary terrain differ, only the most disadvantageous set applies, as MPL/GRM modifiers from two types of secondary terrain do not stack.
Terrain also determines the base maximum source potential (MSP) for a given province. The base MSP in a province without secondary terrain is the MSP (rounded down to the nearest integer) associated with its primary terrain. In provinces with secondary terrain, the base MSP is the highest MSP (again, rounded down to the nearest integer) associated with any terrain present, with one caveat: the MSP of any secondary terrain counts as if it were one category (or 0.5 point) lower than its standard rating.
The following table, TERRAIN I, lists the many types of terrain and related information about MPL, GRM, and MSP; and it also details the overland movement costs associated with each type of terrain for regiments of infantry and of cavalry.
