The new map system is based on hexes, as before. Each hex is a province and is divided into 6 districts. Each district has two parishes. Each parish has a characteristic terrain which is hilly, wooded or farmland.
At the centre lies the provincial capital city which is surrounded by an adjacent parish which is star-shaped. Cities are typical late sixteenth century Vauban-style fortress-towns.
Each nation gets a single major river - Danube or Rhine-sized, which rises on its teritory and flows into the Cold Sea.
Onto the basic province terrain map there is a road net which is superimposed. All junctions represent a market town. Between each market town is a day's march for infantry. Market towns have medieval style town walls.
I made six terrain maps and six road nets which are compatible. Rolling dice decided which two were set together to make a province map.
