But he couldn't keep her out of his mind. "No," she said, "you're wrong. I was not speaking metaphorically. My nervous system is attuned to my people's; it is a hereditary trait bred into my family. So being the ruler is not a pleasant station to occupy."

It certainly wouldn't be, he thought, if she was telling the truth—to suffer every pang that was suffered on the planet, and, if the attuning were psychic also, every sorrow. He expected her to pick the disbelief out of his mind, but she smiled and went on to tell him about her planet.

Ferr was not a large world. Moreover, it was essentially a barren one. It had been rich only because it had previously engaged in sub-rosa commerce with Mattern's universe. "And the last traffic was long, long ago," she told Mattern. "In a day much before mine, when my mother ruled."

"What happened? What stopped the traffic?"

"Our captain died of old age, and we have had trouble finding a successor to him."

"Why is it so hard to get somebody else?" Mattern asked bluntly.

She paused. When she spoke again, it was so obliquely that he did not realize immediately that it was an answer. "Time was when we had more contact with your people. There were many who knew of the xhindi, although few had actually encountered us. It was not difficult for us to get humans to work with us then. But the barbarians took over your world and your people lost the knowledge of how to get through to us. And when they regained it, we were not why they wished to get through. Much of the problem is in making people believe that we exist."

He nodded. "The flluska call you demons."

"There are still some on Earth who call us demons, Mattern. Your rulers and administrators do not call us demons—no, they are too learned for that—but your Space Service, by means of divers spells and conditionings, prevents most of those who pass through hyperspace from seeing and hearing us. And, of those who do, most are too frightened for negotiation."
