Terror Out of Space (Version 2) - Leigh Douglass BRACKETT

"An eerie story of a silver land beneath the black Venusian seas. A grim tale of brooding terror whirling out of space to drive men mad, of a menace without name or form, and of the man, Lundy, who fought the horror, his eyes blinded by his will. For to see the terror was to become its slave—a mindless automaton whose only wish was to see behind the shadowed mysterious eyelids of "IT". From the publishers blurb about this story in Planet Stories, 1944 where it was first given to the public. - Summary by Publisher
