The White Sphere is an alien artifact and probably an artificial intelligence, which fell to Earth in 2506. The device is a white sphere the approximate size of a tennis ball, but heavy enough to require three people to lift.
All available data relating to the white sphere is derived from the surviving records of the EAA Science Division records from the testing between the fall of the sphere and the disappearance of the sphere following its infamous warning on May 1, 2506.
The warning given by the sphere led to the abandonist movement and its exodus from Earth and the Cradle Worlds and the Battle of Vega. Many suspect a tie between the White Sphere and the Scourge who invaded Human Space a mere two days after the exodus of the White Sphere’s followers.
