Master Swordsmith's Forge (Empire) is a Empire resource building in Total War: Warhammer. The Old World has very few master swordsmiths, for they are the finest craftsmen in the realm and always in demand.
Background
To be a master swordsmith takes many years of perfecting your skill to hone blades to their sharpest edges. These men are no mere blacksmiths, they are swordmakers for Kings and Emperors and can command a hefty price for their services.
