A couple of days later Bzya's shifts should have allowed him another break. Adda searched for Farr, but couldn't find him, so he went down to the bar alone. He entered, awkward and self-conscious in his dressings, peering into the gloomier corners.

He couldn't find Bzya, and he didn't stay.

IN THE INTERIOR OF THE STAR there were no sharp boundaries, merely gradual changes in the dominant form of matter as pressures and densities increased. So there was no dramatic plunge, no great impacts as the "Flying Pig" hauled itself deeper: just a slow, depressing diminution of the last vestiges of Air-light. And the glow cast by the wood-lamps fixed to the walls was no substitute; with its smoky greenness and long, flickering shadows, the gloom in the cabin was quite sinister.

To Dura, hunched over herself in her corner of the ship, this long, slow descent into darkness was like a lingering death.

Soon, though, the ride became much less even. The ship swayed alarmingly and at one point was nearly upended. The laboring pigs, their shadows huge on the ship's roof, bleated pathetically; Hork laughed, his eyecups pools of green darkness.

Dura's fingers scrabbled over the smooth wooden walls in search of purchase. "What's happening? Why are we being pummeled like this?"

"Every Bell hits underMantle currents. The only difference is, we've no Spine to steady us." Hork spoke to her slowly, as if she were stupid. Since their single physical encounter, his aloof hostility had been marked. "The substance of the Mantle at these depths is different from our Air... or so my tutors used to tell me. It's still a superfluid of neutrons, apparently, but of a different mode from the Air: it's anisotropic — it has different properties in different directions."

Dura frowned. "So in some directions it's like the Air, and it doesn't impede our progress. But in others..."

"...it feels thick and viscous, and it batters against our magnetic shield. Yes."

"But how can you tell which directions it's Air-like?"

"You can't." Hork grinned. "That's the fun of it."

"But that's dangerous," she said, uneasily aware of how childlike she sounded.

"Of course it is. That's why the Harbor suffers so many losses."

...And this is where I sent my brother, she thought with a shiver. She felt strangely, retrospectively fearful. Here, drifting through this anisotropic nightmare, it was as if she were fearing for her brother for the first time.

Still, after a while Dura found she could ignore — almost — the constant, uneven buffeting. Immersed in the hot, fetid atmosphere of the ship, with the warm stink of the pig-farts and the patient, silent work of Hork at his control box, she was even able to doze.

Something slammed into the side of the ship.
