After Winter Dark Campaign Setting

From the back of the book: For a thousand years the world of Erde was bound to the service of the horned god, Unklar. Ruling from the towers of Aufstrag he blanketed all in Winter's Dark. His reign ended in a wash of rebellion and war. New powers rose in his stead. Men carved new kingdoms from his dying empire, dwarves rose from the ashes of history, and the elves returned from the lands of Fay with a vengeance! The world was born anew!
