Crassus took the newly fabricated device, a small implant designed to be placed into the base of the skull, interfacing with the brainstem. Crassus termed in the "Nodule Synchronisation device mark one" It worked by synchronising all the nodules through controlling the signals from the brain, thus meaning they reached the nodules at the correct time. This would allow the generation of the fields, which would raise or lower the mass of an object, allowing it to be manipulated in a fashion not dissimilar to the Psionic psychokinesis, only instead of manipulating energy to apply force this method manipulated mass, indirectly manipulating the movement rather than directly.
Now to imbed it into the volunteers and hope that they survive...
