All that day they hiked north, threading a complicated path through the Juventa Chaos. That evening they came to a small mesa, its whole cap covered by an apple orchard. A ramp road led the way up to this grove. The trees had been pruned to the shape of cocktail glasses, and now new shoots rose straight up from the gnarled older branches. Through the afternoon they pulled ladders around from tree to tree, pruning the thin shoots away and thereby harvesting some hard, tart, unripe little apples, which they saved.

In the center of the grove was a open-walled round-roofed structure. A disk house, they called it. Nirgal walked through it, admiring the design. The foundation was a round slab of concrete, polished to a finish like marble. The roof was also round, held up by a simple T of interior walls, a diameter and a radius. In the open semicircle were kitchen and living space; on the other side, bedrooms and bathroom. The circumference, now open to the air, could be closed off in inclement weather by clear walls of tenting material, drawn around the circle like drapes.

There were disk houses all over Lunae, the woman who had butchered the antelope told Nirgal. Other groups used the same set of houses, tending the orchards when they passed through. They were all part of a loose co-op, working out a nomad life, with some agriculture, some hunting, some gathering. Now one group was cooking down the little apples, making applesauce for preservation; others were grilling antelope steaks over a fire outside, or working in a smokehouse.

Two round baths right next to the disk house were now steaming, and some of the group were shedding their clothes and hopping into the smaller bath, to clean up before supper. They were very dirty; they had been in the back country a long time. Nirgal followed the woman (her hands still spotted with dried blood) and joined them in the bath, the hot water like another world, like the heat of the fire transmuted to liquid that one could touch, in which one could immerse one’s body.
