Jon looked around but saw no one else. Suddenly another picture, the picture of a world of white desert where the sky was deep blue and each object cast double shadows, filled his mind. "This isn't the world you took me to before ..." he exclaimed.
"No," came the quiet voice, "this is not the world we took you to before. Listen. We are homeless wanderers of space. Our origin was not only in another galaxy, but in another universe, eternities ago. By way of this universe we can move from star to star without transversing any segment of time, unless we desire. Thus we have dwelt quietly in the dead cities of myriad suns till now. We have never tampered with any living species, though there is something in us that yearns for the extinct cultures.
"Recently according to our standards, though still much older than your solar system, a dark force has come into the universe. It has evolved similarly to us, and also leaps among galaxies in moments. Yet it holds no culture sacred that it finds, and has already tampered with a score of civilizations. It is younger than we are, and can only exist in one individual at a time, while our entity has three lobes, so to speak. This rival thinks nothing of completely changing the mind of its host, giving deadly information, even new powers. We are bound only to ride with your minds, warn you, guide you, but changing your body before your minds, and that only to keep you from death. So it will be your own greed, your own selflessness that will eventually win or lose this battle. Therefore it will be won or lost within the framework of your own civilization."
"Then tell us this," came a voice that was not Jon's. "What is on the other side of the radiation barrier?"
"But we have told you already. And you have guessed. Toromon is at war with an economic condition. Beyond the barrier is a civilization which is controlled by the Lord of the Flames. He is only in one member of their number, and any time he may move to another, although it is not likely."
"Are they our enemies?"
"Your only enemies are yourselves. But he must be evicted none the less. To do that, all you must do is confront the individual who is bearing him, the three of you together. But you must all be within seeing distance of him at once. For we work through your minds. What you cannot perceive, we cannot affect."
"How will we do this?"
"One of you has already been made immune to the radiation barrier. So will the rest of you when it becomes necessary. This is what you will do for us, and it will also remove the threatening element of the unknown that distracts Toromon from her own problems."
"But why our planet?" a voice asked.
