So there was to be treachery, Hanson thought. He wasn't surprised. He was probably lucky to have even three friends. The Satheri would hardly feel very grateful to a mandrake-man who had accomplished something beyond their power, now that the crisis was over. They had always been a high-handed bunch, apparently, and he had served his purpose. But he covered his thoughts in a neutral expression and went forward quietly toward the huge council room.

The seventy leading Satheri were all present, with Sather Karf presiding, when Hanson was ushered into their presence. He moved down the aisle, not glancing at the seated Satheri, until he was facing the old man, drawing Nema and Bork with him. There were murmurs of protest, but nobody stopped him. Above him, the eyes of Sather Karf were uncertain. For a moment, there seemed to be a touch of friendliness and respect in them, but there was something else that Hanson liked far less. Any warmth that was there vanished at his first words.

"It's about time," Hanson said flatly. "When you wanted your world saved, you were free enough with offers of reward. But three days have passed without mention of it. Sather Karf, I demand your secret name!"

He heard Nema gasp, but felt Bork's fingers press against his arm reassuringly. There was a rising mutter of shock and anger from the others, but he lifted his voice over it. "And the secret names of all those present. That was also part of the promised reward."

"And do you think you could use the names, Dave Hanson?" Sather Karf asked. "Against the weight of all our knowledge, do you think you could become our master that easily?"

Hanson had his own doubts. There were counter-magical methods against nearly all magic, and the book he had read had been only an elementary one. But he nodded. "I think with your name I could get my hands on your hearts, even if you did your worst. It doesn't matter. I claim my reward."

"And you shall have it. The word of Sather Karf is good," the old man told him. "But there was no mention of when you would be given those names. You said that when the computer was finished you would wait for my true name, and I promised that you should have it when the time came, but not what the time would be. So you will wait, or the agreement shall be broken by you, not by me. When you are dying or otherwise beyond power over us, you shall have the names, Dave Hanson. No, hear me!"

He lifted his hand in a brief gesture and Hanson felt a thickness over his lips that made speech impossible.

"We have discussed your reward, and you shall indeed have it," Sather Karf went on. "Exactly as I promised it to you. I agreed to find ways to return you to your own world intact, and you shall be returned."

For a moment, the thickness seemed to relax, and Hanson choked a few words out through it. "What's the world of a mandrake-man, Sather Karf? A mandrake swamp?"
