Entry hall 447 was the sight transit station that linked the Clepsydra Tower to the Great Silt Basin, housing the delicate condensing lenses and white spar-stone polarization prisms that translated the clock’s clockwork motion into focused beams of light.
On the central Parian marble workbench, Qiao Ming laid out his final tools: a brass sight hair-width, three pairs of bone tweezers, a vial of refined cedar-wood full-body VR oil, and the Folded brass star-compass.
Beside the tools rested the six-inch metal tube of star-fallen quartz, unwrapped from its protective linen.
In the steady, warm lamplight of the workshop, the crystal was breathtaking. Its body was flawless, fully free of the cloudy inclusions or bubbles that plagued mortal glass, possessing an unnatural, diamond-like clarity that seemed to drink in the surrounding light and focus it into glowing amber fire within its core.
Yan Zhiqiu sat upon an ash stool opposite him, her hands steady, her eyes magnifying the crystal through the sighting diopter of her star compass.
“Look at the sixty-four facets,” she said, pointing with a bone metal pen. “Each facet is a sight track. In the royal libraries, our secret codes were written in two dimensions—lines of ink across a flat sheet of thick parchment. But this crystal is a three-space-folding ledger. The alchemists of the Azure Firmament Sect engraved their memories into the stone using focused rays of clear spirit-light, creating thousands of tiny interference patterns inside the crystal lattice.”
