The mental voice ceased abruptly. Then sudden, vivid pictures flashed stereoptically across Jim's brain and were as quickly gone. He saw a city he recognized as M'Tonak, and the city was teeming with people. Jim knew that must have been many, many years ago. The scene changed. As through another's eyes, he caught a blurry vision of this evil entity flashing from out of the sky to land near the city. He felt some of the consternation and then horror as the populace died by the score in the streets. There was no apparent reason except the presence of the alien thing. Just to look at the blinding brilliance of it was to die. Jim caught confused pictures of all available weapons being rushed to the scene to do battle with the thing, but to no avail; as the M'Tonakians died, the entity grew tremendous in proportions and in power. These pictures flashed away and Jim saw others; the last few scientists of M'Tonak, in a barricaded place where they worked frantically on a weapon with which to battle the alien thing. They completed the weapon but they could not destroy the entity. After a terrific struggle they subdued it temporarily by means of certain rays and beams. In this manner they at last brought it into captivity within the glassite well. "Bhruulo says all this happened hundreds of years ago," the voice came again within Jim's brain. "He is the last of that final group of scientists who subdued me. _I_ have only a vague remembrance--" "Bhruulo says!" Jim gasped, struggling with the significance of the idea. He looked up and saw the spherish, effulgent thing spinning with silent amusement. "Is Bhruulo's longevity, then, such an unusual thing? I do not know. Your time-scheme means little to me. Perhaps Bhruulo's great age is due to his perpetual proximity to me, I only know that, unlike other Martians and Earthmen, he is immune to my strongest powers now." Jim sensed a certain bitterness in that mental voice, almost a hatred for Bhruulo. Looking up at the greenish, brooding globe, Jim ventured a daring question. "Don't you sometimes long to be--free again?" He felt the tendril-fingers grasp his mind again with a fierce tenacity. He cried out against the physical pain of it, but even through the pain he heard the throbbing answer. "Free! Yes, Earthman! Bhruulo glories that he has me trapped here. Often I remember those olden days when I almost conquered the city of M'Tonak and the planet Mars! Bhruulo has promised me those days again, and much more. He says he is preparing for it, but I do not know what he means. I only know that I tire of waiting!"
