“There were people who once knew how to harness energies that we haven’t yet discovered, or rather, rediscovered,” Dr. Taisho said as she strapped the leathery cuff around his right wrist. “They did so by learning about the world around them and building tools to understand and then use the forces and energies they observed. Wars and calamities overcame the world and most of the knowledge and the tools were destroyed or lost. There are those in the present time who are trying to regain that knowledge. They are finding some of the tools and devices and testing them to see if they still work. This is one those devices.”
