From the cover: "An old dwarven mine, buried deep in the Abbor-Alz and infested with undead, holds many treasures. Most prized of these are deposits of precious metals brought by a falling star said to be purer than any other in the Flanaess. Now powerful forces struggle for control of the mines but with whom will you side? A one-round Living Greyhawk Core Special adventure set in the Bright Desert and the Abbor-Alz for characters level 1-15 (APLs 2-16)."
