This 144-page supplement helps GMs and players develop a detailed medieval fantasy setting shaped by D20 magic. It provides guidance and game-ready information on kingdoms, cities, manors, aristocratic wealth, landholding, government, religion, and everyday occupations. Generation and construction systems cover settlements, fortifications, economies, and population, while an economic simulator helps determine costs, incomes, cultivated land, building numbers, and other practical details. The material supports campaigns involving abandoned keeps, political influence, noble finances, and the path from adventurer to ruler.
