The earthworks of the Great Frontier Trench stretched across four miles of bitter salt plain like an unstitched wound in the grey clay. For eighteen winters, rain, wind, and frost had gnawed at the low roof walls, melting the crisp, military angles of the stone retaining walls into sagging hummocks choked with yellow dock, wild mustard, and dead thistle stems.
Tomas Reed stepped down into the sunken floor of the trench, his iron-shod boots sinking to the welt in a slurry of cold silt and rotting hazel hurdles. The air below the low roof wall was still, cold, and dead. He smelled of stale sulfur water, decomposed willow bark, and the bitter stone iron of the underlying subsoil. He reached up, grasping the splintered stub of a stone retaining wall post to steady his balance. His left wrist brace hummed with cold stiffness.
He paused on the wet clay bench. That let his fingers flex rhythmically—thumb to index, thumb to middle, thumb to ring, thumb to little finger. Five slow cycles of tension and release brought the warmth back to his scarred thumb joint before he touched the baggage straps. On a winter morning like this, the cold tightened the gristle of his old glass jagged cut until his grip strength dropped by a third. A porter who ignored his tendon care would find his hand frozen open before noon, unable to hold a reins-rope or an iron pen.
