Also, Tractor Ray. The opposite of a presser beam (or ray), the tractor beam is a device, consisting of a force field confined to a collimated beam, which is normally used by a voidfaring craft to retrieve or secure its cargo or passengers. In other words, the Tractor Ray attracts large objects to its source vessel over a distance. During the early cycles of AnarchEra, space-going pirates quickly learned that a ship’s tractor beam (or ray) could be used to waylay the ships of their victims, in much the same way as the pirates of ancient Terran legend purportedly used grappling hooks to trap and board enemy vessels.
