"Lapis blue skies way up high; Limestone peaks beyond your reach; Fields of emerald green beneath your feet." That's what Damien believed the outside world to be -- a 'paradise'. But after escaping a fifteen-year imprisonment from under his father, Damien discovers that the world he yearned to explore had been long overtaken by a lethal, monster-infested fog. Left with nothing to live for, Damien must now face an ultimatum: surrender to death... or change the world.
