Years ago, Earthgov placed Multivac, a medical facility, in a stationary orbit above Mercury. The facility nearly met with disaster when it was discovered that Mercury was home to a native life-form composed entirely of agitated plasma. These Mercurians would unknowingly pass through Multivac's protective dome as well as through some of the facility's patients.
