Yoshii explains the politics behind Lux: At one time it was ruled by the Elder of Gabe, but in recent times the power has switched to Organ because of their military strength and efficient organization. He says that the people of Lux have lost their 'natural healing process' in their bodies. He also says that the Class built their own world to live in isolation from the people of Lux. Doc explains all about the Texhnolyze process. Basically, is connects to the body's nervous system and transmits its own 'neural information' to the brain (hence why people with Texhnolyze have crazy vision). She also explains that the reason it all works is because of Lafia, which is mined in the Mine. Lafia basically relaxes the body's instinct to reject organs that are alien to the body and allows Texhnolyze to sync with the body.
