The "jumper quarries" were marble quarries in the High Ontis region of Ralltiir. By the Imperial Period, the quarries and nearby mines were tapped out and the region's numerous tunnels was used as a base by criminal organizations and the Alliance to Restore the Republic. One Rebel cell formed a tunnel network that reached from the jump quarries to the Grallia Spaceport's Docking Slip 120-54, 40 kilometers away.[1]
