>Dark Earth takes place several centuries in the future, when a meteor collision with Earth (referred to as the "Great Cataclysm") has thrown up great clouds of ash and dust, blocking out the light of the sun. Those not killed in the collision were soon hunted by strange creatures of darkness, and so they began to seek a refuge from the "Dark Earth" - pockets of land where the light of the sun breached the clouds. Eventually they found such places. Called "Stallites", these places of light became cities, and the survivors built temples in honor of the light. The game is set in a Stallite called Sparta.
>By the time of the game, many centuries after the establishment of Sparta, most of the citizens have forgotten their history and now worship the light as a god, Solaar. The city is run by Sunseers, priests of Solaar, who maintain order and prevent the creatures of darkness from entering the city limits. The game focuses on Arkhan, a "Guardian of Fire", one of the military protectors of the city.
