from back cover:
Some of the most powerful super heroes in the uiverse havea tall order ahead of them. They have to enter the realm of DEATH itself to rescue GALACTUS, who is a prisoner there.
That's right. And if the super heroes fail, the very universe may come to an end! The Left Hand of Eternity is designed for cosmically powered super heroes like SILVER SURFER, NOVA, FIRELORD, THOR, and DR. STRANGE--but any character can play.
