地球連邦
In the year 2348, humans have been exploring the vast reaches of outer space for four centuries and have established peaceful contact with various alien civilizations. People now emigrate from one planet to another. However, some problems arise with a couple of alien races, so the Earth Federation begins developing a Plasma-power weapon to protect the Earth from any outside threats. Dr. Edward Bilstein, a Nobel Prize-winning German-American physicist for the Earth Federation, uncovers the secret to humanity's "sixth sense": a technique for capturing the energy of the human mind, an energy source he calls "Plasma Power". The Plasma weapon is built, and Bilstein gains fame and fortune for the invention. It is discovered by the Earth Federation that Bilstein experimented on actual human bodies during his research on Plasma Power. He is arrested and exiled from Earth, imprisoned in a satellite that orbits the Planet Zeta, while development of the Plasma weapon is indefinitely suspended. Word of Earth's possession of a super weapon spreads throughout the universe and it reduces hostile confrontations.
