Ace Books, 1972
Price I paid: 75¢
Two alien powers contended for that world. One, Eliff, had assumed a godlike identity; the other, Udrig, imprisoned beneath the polar ice cap, was branded as the evil one―the would-be destroyer of the planet.
Unknown to himself, Teron of Korv was the key to their conflict. If he could meet the right girl, the noble Eldra the Seventh, and if they could combine their powers―the fight would be resolved.
Against that meeting worked Udrig’s human agents, certain that the legends were wrong and Udrig was truly the Good One. In favor of the meeting was Eldra herself and the mysterious forces of the orbiting Eliff.
Guardians of the Gate is a space adventure reminiscent of the questing of Tolkien, the legendry of Merritt, and the action of Andre Norton.
