Again rays struck at it. Cosmic and moleculars with blinding pencils of light. For now in the close space of the Wall was an atmosphere, the air of two great warships, and though the space was great, the air in the ships was dense.

The rays struck its awful face. The face burst into light, and black, greasy smoke steamed up, as the thing writhed and twisted horribly, awful screams ringing out. Then it was free, and half the face was burned away, and a grinning, bleeding, half-cooked face writhed and screamed in anger at them. It darted at the nearest ship, and ripped out that ray that burned it—and quivered into death. It quivered, then quickly faded into mist, a haze, and was gone!

A last awful thing—a thing they had not noticed as all eyes watched that Thing—was standing by the rent in the Sphere now, the gigantic Thessian, with leering, bestial jaws, enormous, squat limbs, the webbed fingers and toes, and the heavy torso of his race, grinning at them. In one hand was a thing—and his jaws munched. Thett's men stared in horror as they recognized that thing in his hand—a Thessian body! He grinned happily and reached for a battleship—a ray burned him. He howled, and leaped into their midst.

Then the Thessians went mad. All fought, and they fought each other, rays of all sorts, their moleculars and their cosmics, while in their midst the Giant howled his glee, and laughed and laughed—

Eventually it was over, and the last limping Thessian ship drove itself crazily against the wreck of its last enemy. And only wreckage was left.

"Lord, Arcot! Why in the Universe did you do that—and how did you conceive those horrors?" asked Morey, more than a little amazed at the tactics Arcot had displayed.

Arcot shook himself, and disconnected his controls. "Why—why I don't know. I don't know what made me do that, I'm sure. I never imagined anything like that dragon thing—how did—"

His keen eyes fixed themselves suddenly on Zezdon Fentes, and their tremendous hypnotic power beat down the resistance of the Ortolian's trained mind. Arcot's mind opened for the others the thoughts of Zezdon Fentes.

He had acted as a medium between the minds of the Thessians, and Arcot. Taking the horror-ideas of the Thessians, he had imprinted them on Arcot's mind while Arcot was at work with the controls. In Arcot's mind, they had acted exactly as had the ideas that night on Earth, only here the demonstration had been carried to the limit, and the horror ideas were compounded to the utmost. The Thessians, highly developed minds though they were, were not resistant and they had broken. The Allies, with their different horror-ideas, had been but slightly affected.

"We will leave you on Ortol, Zezdon Fentes. We know you have done much, and perhaps your own mind has given a bit. We hope you recover. I think you agree with me, Zezdon Afthen and Inthel?" thought Arcot.
