The last gleaming sliver of Komarr’s true-sun melted out of sight beyond the low hills on the western horizon. Lagging behind it in the vault of the heavens, the reflected fire of the solar mirror sprang out in brilliant contrast to the darkening, purple-tinged blue. When Ekaterin had first viewed the hexagonal soletta-array from downside on Komarr’s surface, she’d immediately imagined it as a grand Winterfair ornament, hung in the sky like a snowflake made of stars, benign and consoling. She leaned now on her balcony overlooking Serifosa Dome’s central city park, and gravely studied the lopsided spray of light through the glassy arc overhead. It sparkled deceptively in contrast to the too-dark sky. Three of the six disks of the star-flake shone not at all, and the central seventh was occluded and dull.

Ancient Earthmen, she had read, had taken alterations in the clockwork procession of their heavens-comets, novae, shooting stars-for disturbing omens, premonitions of disasters natural or political; the very word, disaster, embedded the astrological source of the concept. The collision two weeks ago of an out-of-control inner-system ore freighter with the insolation mirror that supplemented Komarr’s solar energy was surely most literally a disaster, instantly so for the half-dozen Komarran members of the soletta’s station-keeping crew who had been killed. But it seemed to be playing out in slow motion thereafter; it had so far barely affected the sealed arcologies that housed the planet’s population. Below her, in the park, a crew of workers was arranging supplemental lighting on high girders. Similar stopgap measures in the city’s food-producing greenhouses must be nearly complete, to spare them and this equipment to such an ornamental task. No, she reminded herself; no vegetation in the dome was merely ornamental. Each added its bit to the biological reservoir that ultimately supported life here. The gardens in the domes would live, cared for by their human symbiotes.
