The Visitor
The Visitor is a large extraterrestrial spacecraft occupying Earth orbit and regularly circumnavigating the globe. After its arrival in 2017, the Visitor destroyed electrical power around the world and caused the rapid decline and self-desctuction of human civilization.
Description
The Visitor is a large, regular triangular-shaped spacecraft approximately 93 miles wide and six miles tall. It appears to be made from a dull, dark-grey metal. There are no visible windows, joins, centers of control, communication arrays, or means of propulsion.
The Visitor appears to have some type of display located on its bottom, which can be observed from the surface with the assistance of binoculars or a telescope. This display lights up with odd, twisted symbols that may bear some resemblance to the ancient language of Enochian. Cultists who worship the Visitor as the hand of God, or a god in its own right, are convinced this is its attempt to communicate with people. There have been no known successful efforts to decipher the message, if it is in fact a message.
Orbit
The Visitor orbits at the lower edge of the mesosphere, about 31 miles above Earth. It takes three days to circle the world, generally moving from North America down to Africa and then back up again through Asia in a steady pattern.
Effects
As it orbits, the Visitor emits strange energies that interfere with the operation of electronics. Anything with wires will be shorted out when the Visitor gets within 5,000 miles. Even simple flashlights fail when the Visitor comes back into range. It is also believed the energies emitted by the Visitor affect local weather patterns as the arrival of the Visitor is usually preceded and followed by severe thunderstorms.
