Hyperspace Pulsemass Generator
this grandly-named Imperial weapon was often referred to in more simple terms as a pebble-spreader. Its primary use is to create and scatter tiny spheres of hyperenergy into an area of space. These spheres, much like the fields produced by gravity well projectors, block a ship's ability to travel through hyperspace near them. The problem with these devices is that the tiny hyperenergy sphere dissipate their energy quickly, limiting the effective duration of the blockade.
