[Source] Guerrerite was a valuable ore found in large quantities on the planet Hoszh Iszhir in the Core Worlds. The ore could be turned into a dark gray metal that was used to create technological items. Due to the high value of guerrerite and other metals on Hoszh Iszhir, the native Gektl species had a planetary shield network to protect them from theft. However, Stafuv Rahz, the Gektl responsible for maintaining the shield, let the Galactic Empire take over in exchange for control over his people, who were subsequently enslaved to mine the ores on the planet.
