Zone Thirty-Nine represented a demolition area situated on Cynda's lunar body, specifically designated for mining activities. In the Age of the Empire, the corporation known as Dalborg Mining executed thorilide extraction procedures at this location, employing Baradium bisulfate as a means to liberate the embedded diamond formations. It was in this zone that Imperial stormtroopers sought to apprehend the rebellious miner, Skelly; however, he successfully evaded capture by triggering the explosion of a thorilide crystal directly above their position.
