Edda had spent eight seasons working the limestone drifts of Tier Four. She knew the sound of dying stone long before the dust began to fall.
When a hanging wall gave up its solid strength, it didn’t scream or crack like seasoned timber. It hummed first—a deep, low-hum shudder that traveled through the soles of a driller’s boots and shook inside the marrow of the shinbones. Then came the spall. Tiny, razor-sharp flakes of white spar-stone spitting from the bedding planes as the crushing load exceeded the stone’s shear limit. Only after the spall had peppered a crew’s leather aprons did the true failure arrive. It tore through four-course stonework with the dull, muffled crunch of a falling mountain.
Edda stood three feet from the breach in the granite solitude wall. He felt that exact shaking humming through the soles of her heavy quarry clogs.
Her braced left forearm was bound tight against her midriff inside the bib of her leather apron, the coarse linen wraps stiff with dried vinegar and yellow pus from the earlier roof fall in the southern drift. Her thumb and forefinger were blackened, swollen to twice their natural girth where the iron drilling guide had clipped her hand. Every breath she drew dragged the sharp, bitter-salt sting of crushed lime into her lungs. That made her ribs ache beneath her coarse woolen tunic.
