Dura forced herself to smile. "It's a long story."

Rauc squeezed Brow's arm. "She can tell you later."

Brow rubbed his nose, still staring at Dura. "We see upfluxers sometimes. In the distance. When we're working in the far upflux, right at the edge of the hinterland. You see, the further upflux you go toward the wild forests, the better the trees grow. But..." He stopped, embarrassed.

"But the more dangerous it gets?" Dura maintained her smile, determined for once to be tolerant. "Well, don't worry. I don't bite."

They laughed, but it was forced.

Rauc introduced the woman with Brow. She was called Kae, and she and Rauc embraced. Dura observed them curiously, trying to make sense of their relationship. There was a stiffness between Rauc and Kae, a wariness; and yet their embrace seemed genuine — as if on some level, beneath the surface strain, they shared a basic sympathy for each other.

Brow tugged at Rauc. "Come and see the others; they've missed you. We're going to eat shortly." He glanced at Dura. "Will you join us?"

The woman Kae approached Dura with brisk friendliness. "Dura, let's leave these two alone for a while. I'll show you around the caravan... I don't suppose you've met people like us before..."

—

Dura and Kae Waved side by side along the length of the caravan. Kae pointed out features of the caravan and described how it worked in a brisk, matter-of-fact way, her talk laced with endless references to Dura's assumed ignorance. Dura had long since grown tired of being treated as an amusing freak by these Parz folk, but — for today — she bit back the acid replies which seemed to come so easily to her. This woman, Kae, didn't mean any harm; she was simply trying to be kind to a stranger.

Maybe I'm learning to look beneath the surface of people, Dura wondered. Not to react to trivia. She smiled at herself. Maybe she was growing up at last.

The chain of trunks slid through the Air at about half an easy Waving speed. There were teams of harnessed Air-pigs, their harness sets fixed — not to Air-cars — but to the rope links in the chain of trees. The pigs squealed and snorted as they hauled at their restraints of leather. Humans, some of them children, tended the animals. The pigs were fed bowls of mashed-up Crust-tree leaf, and their harnesses were endlessly adjusted to keep the teams hauling in the same direction, along the long line of trunks.

People hailed Kae as she passed, and they glanced curiously at Dura. Dura guessed there must be a hundred people traveling with this caravan.

The women paused to watch one team being broken up. The animals were released from their harnesses, but they were still restrained by ropes fixed to pierced fins. The animals were led away to be tied up in another part of the caravan to rest, while a fresh team was fixed into place.
