In the most ancient of days visitors from the stars came to the earth. During the first age of man they walked the earth with the race called Adam; teaching them the basic elements of science and civilization. Through the centuries, myth and legend reflected an ancient but incomplete understanding of these events. Throughout the ages artifacts have been discovered that point to a glorious history in the ancient past; and perhaps an uncertain future. A strange tablet unearthed in the 1930's by a German archaeological team may be the key to unlocking the mystery of the origin of man. The artifact is discovered to be a powerful example of extra terrestrial techlogy that leads Dr. Samuel Ech to a mysterious object on the outer fringe of the solar system. Will this discovery lead to the extinction of humanity? Or will it save our world from certain destruction?
