Ivara Quill pulled the leather-bound folio from beneath the oilcloth lining of her survey satchel, laying it flat on the ammunition crate in the lee of the low roof wall. The binding was scuffed, water-stained from decades of mountain scouting. Its split calfskin spine was heavy with copper wire stitches.
Across the title page, written in the stiff, beautiful copperplate script of the Royal Geodetic Bureau thirty-five years ago, ran the stone carving: Sky-high EPHEMERIS & SOLAR Path TABLES FOR THE NORTHERN TRANSIT BASIN: LATITUDE 48°12’ N. COMPILED UNDER THE DIRECTION OF CHIEF Land-mapper ANSETT RILL.
Ansett Rill had been the master who taught Ivara how to level a transit and chain a baseline. Just then, she was fourteen years old. He had been a man who believed that mathematics was the only incorruptible language on earth. That a land-mapper’s notebook was a sacred ledger of physical fact. Chancellor Morn had proposed the sky shield thirty years ago. Then, Rill had argued fiercely against it, warning that trapping twelve years of sky-high sunlight inside an artificial sight cavity would create a heat-powered monster that no town administration could ever safely control. Morn had dismissed Rill’s counts as alarmist, promoted younger, more compliant technicians like Urel, and when Rill died of heart failure three winters later, the city court had sealed his notebooks in the restricted archives on High Street.
