My name sighed from the pale lips of Verel, and her body went limp in the silver tentacles that held her. Kel Aran had not moved again. I was left alone to face the stalking monster.

The gigantic robot came to the brink of that pool of darkness, and stood swaying there. The swarm of his guards were dwarfed about his feet. The bright blue lenses surveyed us coldly for a time, and then a thick, bronze-throated voice rasped thunderously:

"I know you, Bari Horn. I believed that I had killed you in your laboratory, a million years ago. How your puny lump of watery flesh has survived this time I do not know—but now you face a better weapon than I had that day."

In the shaft of red from above, the iron giant swayed in grotesque triumph.

"No trick even of yours, my maker," came that mighty rumble again, "can match the power of my geodesic mirror. For it deflects the lines of space at my will. The dimensions of space and time are no barriers to the mirror. I can hurl you out of this universe. And I shall—"

The great voice sank rustily.

"—after you are dead."

Desperately, I groped for some argument that might induce the robot to spare some fraction of mankind. Malgarth was a machine. He must respond to logic.

"Consider, Malgarth," I gasped through the strangling coils about my throat. "A man made you. Machines and men are complements. Either would be less without the other. You are stronger than I—but steel must rust, and life is eternal!"
