"Planet Krypton was born over 6 billion time cycles ago from a gaseous
mass flung off by our giant red sun. Yet, until only 10,000
years ago, Krypton was still primitive wilderness - but in those
100 centuries, a race of intellectual supermen evolved and a
scientific empire was born!
"It is a world of awesome beauty - with such wonders as the
jewel mountains - monstrous peaks of pure crystal... formed of
the skeletons of giant crystal birds which filled the skies of
prehistoric Krypton.
"But men dared challenge this world's often brutal nature,
successfully carving their cities into the harsh frozen wastes of
Krypton's poles - creating the dazzling splendor of Antarctic City!
"Thus the greatest civilization in the history of our world came
to be - for never have the people of Krypton hesitated in facing
the unknown - nor have we ever turned from any quest for
knowledge which could bring us even greater glory as a people!"
