The forge master Gratz, a Human, ran the Gratz Foundry, a foundry located in the Boneyard of the city on the planet Nox. While fleeing the Je'daii Order in 25,793 BBY, the darksiders Daegen Lok and Xesh arrived at the Gratz Foundry, where Xesh used the foundry's equipment to create a pair of Forcesaber weapons.
