A conflict unfolded in the Thanium sector, specifically a clash between the Galactic Republic and the rebuilt Sith Empire, during the Galactic War of 3639 BBY. The Mandalorian leader Rimark managed to pilfer the design schematics for the Void Anvil, a clandestine Republic mining and shipbuilding facility. He then sought to trade these plans to the Empire amidst a minefield located within the Thanium sector. Nevertheless, the Republic forces intercepted Rimark, leading to the destruction of the shuttle that contained the stolen blueprints.
