The slave shuddered as the dour, slow-moving overseer began walking stiffly toward them. "Don't let the fact that he's an overseer fool you. He's smarter than most of his kind, but just as ugly. He's a mandrake, and you can't afford to mess with him."

Hanson looked at the ancient, wrinkled face of the mandrake and shuddered. There was the complete incarnation of inhumanity in the thing's expression. He passed ropes around the corners until the mandrake turned and rigidly marched away, the blows of his whip falling metronome-like on the slaves he passed. "Thanks," Hanson said "I wonder what it's like, being a true mandrake?"

"Depends," the slave said easily. He was obviously more intelligent than most, and better at conserving himself. "Some mandrake-men are real. I mean, the magicians want somebody whom they can't just call back—direct translation of the body usually messes up the brain patterns enough to make the thinkers hard to use, especially with the sky falling. So they get his name and some hold on his soul and then rebuild his body around a mandrake root. They bind his soul into that, and in some ways he's almost human. Sometimes they even improve on what he was. But the true mandrake—like that one—never was human. Just an ugly, filthy simulacrum. It's bad business. I never liked it, even though I was in training for sersa rating."

"You're from this world?" Hanson asked in surprise. He'd been assuming that the man was one of the things called back.

"A lot of us are. They conscripted a lot of the people they didn't need for these jobs. But I was a little special. All right, maybe you don't believe me—you think they wouldn't send a student sersa here now. Look, I can prove it. I managed to sneak one of the books I was studying back with me. See?"

He drew a thin volume from his breechclout cautiously, then slipped it back again. "You don't get such books unless you're at least of student rating." He sighed, then shrugged. "My trouble is that I could never keep my mouth shut. I was attendant at one of the revivatoria, and I got drunk enough to let out some information about one of the important revival cases. So here I am."

"Umm." Hanson worked silently for a minute, wondering how far coincidence could go. It could go a long ways here, he decided. "You wouldn't have been sentenced to twenty lifetimes here by the Sather Karf, would you?"

The slave stared at him in surprise. "You guessed it. I've died only fourteen times so far, so I've got six more lives to go. But—hey, you can't be! They were counting on you to be the one who really fixed things. Don't tell me my talking out of turn did this to you."

Hanson reassured him on that. He recognized the man now for another reason. "Aren't you the one I saw dead on his back right next to me this morning?"

"Probably. Name's Barg." He stood up to take a careful look at the net of cording around the stone. "Looks sound enough. Yeah, I died this morning, which is why I'm fairly fresh now. Those overseers won't feed us because it takes time and wastes food; they let us die and then have us dragged back for more work. It's a lot easier on the ones they dragged back already dead; dying doesn't matter so much without a soul."
