Previously Harrison-Meyer Steelworks, Graves-Meyer Steelworks (commonly abbreviated as GMS) is a manufacturing corporation and the ruling body of the Vuurstahl Empire. Though originally an arms manufacturer, the heavy sanctions imposed by the Tempestian Union, along with the resignation of its former leader, led to Gearwinder Dietrich Meyer focusing on post-war diversification. Many of its subsidiaries have since found new fields to explore in addition to their previous work on mech design, and Vuurstahl is back on its way to becoming the most productive nation on Tempestas.
