As they ate they learned more about the sanctuary, mostly from Ariadne, who sat beside them. It had been built and occupied by the descendants of people who had come to Mars and joined the disappeared in the 2050s, leaving the cities and occupying small refuges in this region, aided in their efforts by the Sabishiians. They had been heavily influenced by Hiroko’s areophany, and their society was described by some as a matriarchy. They had studied some ancient matriarchal cultures, and based some of their customs on the ancient Minoan civilization and the Hopi of North America. Thus they worshipped a goddess who represented life on Mars, something like a personification of Hiroko’s viriditas, or a deification of Hiroko herself. And in daily life the women owned the households, and would pass them on to their youngest daughters: ultimogeniture, Ariadne called it, a custom of the Hopi. And as with the Hopi, men moved into their wives’ houses on marriage.

“Do the men like it?” Art asked curiously.

Ariadne laughed at his expression. “There’s nothing like happy women for making happy men, that’s what we say.” And she gave Art a look that seemed to pull him right over the bench toward her.

“Makes sense to me,” Art said.

“We all share the work— extending the tunnel segments, farming, raising the children, whatever needs doing. Everybody tries to get good at more than just their specialty, which is a custom that comes from the First Hundred, I think, and the Sabishiians.”

Art nodded. “And how many of you are there?”

“About four thousand now.”

Art whistled his surprise.

That afternoon they were taken down the tunnel through several kilometers of transformed segments, many of them forested, and all containing a large stream that ran down the floor of the tunnel, widening in some segments to form big ponds. When Ariadne brought them back up to the first chamber, called Zakros, almost a thousand people showed up for an open-air meal in the largest park. Nirgal and Art wandered around talking to people, enjoying a plain meal of bread and salad and broiled fish. The people there appeared receptive to the idea of a congress of the underground. They had tried something like it years before, but had not gotten many takers at the time— had lists of the sanctuaries in their region— and one of the older women said, with authority, that they would be happy to host it, as they had a space large enough to handle a great number of guests.

“Oh, that would be marvelous,” Art said, glancing at Ariadne.

Later Nadia agreed. “It will help a lot,” she said. “A lot of people will be resistant to the idea of a meeting, because they suspect the First Hundred of trying to take charge of the underground. But if it’s held here, and the Bogdanovists are behind it . . .”
