The Torvil Anfract has a bad reputation, but the reality is worse. Phrases like “multiply-connected space-time” and “macroscopic quantum phenomena” don’t tell the half of it. Anfract is the noun formed from the adjective anfractuous, which means full of twists, turns, and windings; but that gives no more than a flavor of the real thing. Even the knowledge that the whole Anfract is a Builder artifact, of unimaginably vast proportions, fails to deliver the right message.

Of more significance is the fact that less than a quarter of the ships that have entered the Anfract have ever come back to report what they found there. If getting in is difficult, it is nothing compared to the problem of getting out.

Louis knew all that. For seven full days, the Indulgence had crawled alongside granular sheets of quantum anomalies, seeking an opening, or eeled its way through knotted space-time dislocations. For all that time, Louis had watched Atvar H’sial snoozing, and had thought dark thoughts.

Cecropians were accustomed to having sighted slaves who did all their dog work. Atvar H’sial, deprived of her Lo’tfian slave, J’merlia, seemed to be taking Louis Nenda for granted as an acceptable substitute. She never gave a thought to the fact that Louis might miss his own Hymenopt slave, Kallik, at least as much as she missed J’merlia. And she blithely assumed that he would bring them out of the Anfract, with not one ounce of help from her.

For seven days Louis had got by with catnaps in the uncomfortable pilot’s chair. He had made bathroom runs — literally — and wolfed down his meals in spare seconds. Atvar H’sial, for the few hours a day that she had been awake, had spent her time in the galley, making evil-smelling liquid refreshments to suit her exact tastes.
