As a king of the holy realm, your God-given task is to expand your kingdom and be triumphant over all who try to oppose you. But remember, not everyone can be king, only those who fully balance their growing economy will succeed. Your army is important to expand your reach as well as protect those who serve under you, build castles to enable a growing army. But your population will also want homes to live in, for this they will produce gold from trade and work your farms for food.
