“What was it?” he asked a little breathlessly.

“I don’t know: it was something terrific. I think it’s still watching us.”

“Shall we leave?”

“No: I was frightened at first, but I don’t think it will harm us. It seems simply-interested.”

Alvin was about to reply when he was suddenly overwhelmed by a sensation unlike any he had ever known before. A warm, tingling glow seemed to spread through his body: it lasted only a few seconds, but when it was gone he was no longer Alvin of Loronei. Something was sharing his brain, overlapping it as one circle may partly cover another. He was conscious, also, of Theon’s mind close at hand, equally entangled in whatever creature had descended upon them. The sensation was strange rather than unpleasant, and it gave Alvin his first glimpse of true telepathy-the power which in his race had so degenerated that it could now be used only to control machines.

Alvin had rebelled at once when Seranis had tried to dominate his mind, but he did not struggle against this intrusion. It would have been useless, and he knew that this intelligence, whatever it might be, was not unfriendly. He relaxed completely, accepting without resistance the fact that an infinitely greater intelligence than his own was exploring his mind. But in that belief, he was not wholly right.

One of these minds, Vanamonde saw at once, was more sympathetic and accessible than the other. He could tell that both were filled with wonder at his presence, and that surprised him greatly. It was hard to believe that they could have forgotten: forgetfulness, like mortality, was beyond the comprehension of Vanamonde.

Communication was very difficult: many of the thought-images in their minds were so strange that he could hardly recognize them. He was puzzled and a little frightened by the recurrent fear-pattern of the Invaders; it reminded him of his own emotions when the Black Sun first came into his field of knowledge.

But they knew nothing of the Black Sun, and now their own questions were beginning to form in his mind.

“What are you?”
