"This was just a secondary job, done in passing," he said, "but it's a good thing we found this out when we did. It'll change our whole primary plan. Now, we'll have to slog it out the hard way. On no account can anyone refract. It might be suicide. We'll have to talk to travelers. We want to know what abnormal or unusual developments have taken place in what country in the last twenty years. Then, we'll have to check them out. We've got a lot of work to do." He looked around. "Ciernar."

"Yes, sir?" The communications operator looked up.

"Send in a report on this to Group. Make it 'operational.'"

Konar tilted his head a little. "Say, chief, you said the transvisor's fear was amplified by my mentacom. What if I wasn't wearing one?"

"You wouldn't feel a thing," Meinora smiled. "But don't get any ideas. Without amplification, you couldn't control your shield properly. You'd have protection, but your refraction control's entirely mental, and levitation direction depends on mental, not physical control, remember?"

"But how about you? You don't use amplification. Neither do several of the other team chiefs."

Meinora shrugged. "No," he admitted, "we don't need it, except in abnormal circumstances. But we don't go around scaring transvisors. They can't kill us, but they can make us pretty sick. You see we're a little sensitive in some ways." He shook his head. "No, the only advantage I've got is that I can spot a transvisor by her mental pattern—if I get close enough. There's a little side radiation that can be detected, though it won't pass an amplifier. When you've felt it once, you'll never forget it. Makes you uncomfortable." He smiled wryly.

"And you can believe me," he added, "when I do get close to a transvisor, I'm very, very careful not to frighten her."
