Psi-wave device

A psi-wave device.

Psi-wave devices are implants used by the Prytt for interrogation purposes. They are connected directly to the brain stem of an individual and slowly adapt to their psi-waves, eventually allowing the Prytt direct access to the individual's memory engrams. The devices can also be calibrated to connect two individuals, making them unable to move too far from one another without causing both to experience nausea. While the main purpose of this is to keep prisoners from wandering too far from one another, it also has the side effect of allowing them to read one another's thoughts.
