An orbiting light planet, Prospit, is charged with its defense, while the distant dark planet of Derse covets its destruction. The Armies of Light and Darkness duel there in a perfect stalemate until a player prototypes a Kernelsprite. Then, their real battle begins, one that Prospit is destined to lose. The planet at the center of Skaia is known as The Battlefield, which hosts the war between the forces of Prospit and Derse. The Battlefield is portrayed as a chessboard.
