Layroh was abruptly interrupted by a scream of maniacal fury from Olsen, a shambling Swede who stood near the edge of the group. Ever since Layroh's unmasking the Swede had been staring at him with eyes rigidly wide in terror like those of a bird confronting a snake. The steady contemplation of the horror of the blaring red thing behind Layroh's empty eye-sockets had apparently at last driven the Swede completely insane. He snatched a revolver from his belt as he leaped forward, and fired once. His shot struck Layroh in the forehead. The bullet ripped through the surface of Layroh's face, then glanced harmlessly aside as it struck metal underneath. Layroh never even staggered from the impact. The black ray from the projector caught Olsen before he could fire again. There was a searing flash of flame, then a swiftly melting cloud of blue-white radiance, and the Swede was gone. Layroh swung the projector back to menace the others. "I had forgotten that _yaharigans_ of Earth have weapons that might be annoying," he said evenly. "Two more of you have pistols--Garrigan and Ransome. Toss them away from you at once. Hesitate--and the black ray speaks again." Sullenly the two men obeyed his order. "Good," commended Layroh. "In the pits where you are going you will have little use for pistols. When I again take you from those pits you will quickly learn why I brought you with me. _Yaharigans_, I have called you, and _yaharigans_ you shall be--Earthly counterparts of those miserable beasts of Rikor who have for ages been bred only for the one purpose of supplying food for the Shining Ones. I knew that when I found the cavern the process of awakening the Shining Ones would require that they be carefully fed with the calcium and lime from the bones of living _yaharigans_, the normal food of all Rikorians. * * * * * "The few _yaharigans_ I had brought from Rikor were consumed on my long trip to Earth. So I had to recruit a party of human beings to go with me and serve as the necessary food for the Shining Ones. My search for the cavern took longer than I had expected for I knew only its approximate location. My own body at last had to have sustenance. Last night the Negro, Jeff Peters, provided that sustenance. "I shall feed those of you who remain to the first group of Shining Ones to be awakened. After that we shall be strong enough in numbers to sally forth and capture ample food for awakening the rest of our comrades. Then in our full strength we shall emerge and again become masters of a planet upon which your crude race shall exist only as _yaharigan_ herds for our sustenance." Layroh's resonant voice ceased. Keeping the black ray projector alertly covering the men, he strode over to a closed metal door in the wall just beyond them. He took a small tube from a rack beside it and opened the door by sending a flash of yellow light into the mechanism of its lock.
