Gundark, a moniker used by an arms dealer, was the head of his own arms ring and was the author of the illicit datalog Gundark's Gear Datalog. His operations were mainly based in the Outer Rim, with sightings reported on locations such as Elshandruu Pica, within the Minos Cluster, and also in the Parmic sector. Gundark's business involved trading military-grade weapons, military-grade explosives, and items that were stolen; furthermore, he was thought to have had connections to Black Sun in the past. His stocky physique hinted at origins on a world with significant gravitational pull, and he kept his face hidden using a sunvisor or goggles at all times.
