Boosters are a cybernetic form of body-improvement, achieved by implanting metallic and synthetic components into the living body along with command and control electronics and sensors that are directly linked to the subject's nervous system. Originally developed as prosthetics to replace lost limbs, elective 'boosters' are now commonplace with the galactic militaries, though still relatively rare with civilians.

As Torei has access to advanced biotech as an alternative way to improve on the human body, booster technology never really took hold there. The only thing that comes close is the dreaded stimhibitor 'jewelry' that also features a nerve-machine interface, albeit for more nefarious purposes.
