A nickel-iron fist seemed to be hanging in the volume of space she had just swept out above the beach. The Kulak. Stout spars jutted from it here and there: anchor points for hair-thin lines of rigging that extended in various directions, seeming to disappear in the vast distance. Moving carefully lest she turn an ankle on a cobble, Kathree circled around it until she could peer down the hole in the center. There, she saw movement: rings of light, each of them similar to the Great Chain, stacked up the interior, each spinning at a different rate, but all protected within the lumpy shell of the asteroid, many kilometers thick. This triggered a programmed camera movement that took her by surprise and obliged her to plant her feet and steady herself by laying a hand on Cantabrigia Five’s forearm. The povv, or point of virtual view, took a slow dive down the center of the Kulak, which had now expanded far beyond the basket-sized volume to surround her. She could not control the speed of the movement but she could gaze in all directions and see through the glass roofs of the ring-shaped cities, picking out green fields where youngsters were kicking balls, blue ponds around which lovers strolled hand in hand, bustling high-rise districts, residential utopias, cozy schools, and military bases where Betas and Neoanders practiced martial arts and marksmanship under the billowing red flag.
