No power on earth, not even the empire, could force the Dwarves out of their mountain homes. They are the masters of iron and stone, and their fortresses are unbreakable.
Out of their mountains they did come, however, by the hundreds of thousands. The sweet aroma of wealth and fame drew them out as surely as the smell of cheese brings the mouse to the trap. Once the war for Sargothia had been won, there were cities to rebuild and plans for more to be built.
Bridges, aqueducts, walls and roadways all needed the masterful touch of Dwarven craftsmanship to meet the needs of man. Common wares were no longer sufficient and the human race possessed the wealth of seven kingdoms to pay the Dwarves for their best.
Imperial trade coin is minted of copper not gold, but its value is just as good and sometimes higher than the yellow metal. For their expertise, the Dwarves were made wealthy and given high status among men.
