The Widening Seam

Behind them, forty people and twelve oxen froze in place, pressing their shoulders flat against the inner limestone wall. Even the draft oxen understood the void. The heavy animals leaned inward, their muffled hooves shifting with gentle scuffs that made no more noise than dry leaves blowing across sand.

Faris watched a hairline seam along a dolomite shelf four paces ahead of Kian-dar’s boots widen by a fraction of an inch. A thin trickle of white dust spilled over the edge, dropping soundlessly into the gorge. Kian-dar waited without moving a muscle until the dust cleared, then took a long, balanced stride across the split, planting his split-leather boot on a solid outcrop of dark basalt. He turned back, tapping the exact spot on the stone where Faris’s foot should land.

Faris stepped across, catching the firm basalt with the ball of their foot. Reaching back, Faris took the lead halter of the dun bull, easing the animal forward with a steady, unbroken pull. The bull paused, its nostrils flaring as it caught the draft of empty air rising from the drop, but Faris held the line firm, offering steady support rather than a violent yank. The bull yielded to the steady tension, stepped across the fracture with its muffled hooves, and brought its four-hundred-pound burden safely onto the basalt shelf.

One by one, the twelve beasts and forty survivors crossed the first fault line without dislodging a single stone.

As the afternoon baked the western scarp, the air against the rock was as dry and burning as a baker's oven. The sharp, alkaline stench of calcined marl mingled with the oily smell of sheep tallow and hot leather, leaving a metallic taste of lye on the back of Faris’s tongue. Faris’s forearm burned from maintaining constant tension on the guide line, but their mind ran the numbers with cold, practiced precision: three thousand paces traversed, nearly two hundred feet of elevation gained, thirty-five pints of water drawn for the handlers during the brief halt at the mid-ledge alcove, eight hours of daylight left before dusk turned the narrow shelf into a fatal trap.

Ahead, the High Spire trail narrowed dramatically as it approached the Devil’s Rib—a sharp, outward-jutting buttress of fractured slate where the canyon wall bent hard to the south.

Kian-dar halted ten yards before the turn. He dropped to one knee on the path, clearing away a layer of loose shale chips with his forearm to examine the underlying rock. His hood fell forward over his forehead, obscuring his expression, but the hard angle of his shoulders signaled trouble.

He looked back at Faris, holding up four fingers, then pointing straight down into the gulf.

Four-foot gap. Sheer slate ledge with underlying structural shearing.

Faris moved forward along the cliff face, sliding their back against the hot, chalky rock until they stood beside Kian-dar’s shoulder.

The buttress was a knife-edge. The shelf had dwindled to less than twenty-eight inches—barely wide enough for a broad-backed ox to squeeze past the overhanging wall with its water bladders. To make matters worse, a section of the rock had broken away during the primary collapse, leaving a fragile span of gray shale held together by nothing more than compacted red clay and dried lichen.

If an ox stumbled or scraped its pack frame against the inner rock wall, the lateral shock would blow the brittle bridge into the canyon.

Kian-dar met Faris’s eyes, his expression unreadable beneath his dust-caked brow, his fingers resting lightly on the hilt of his short knife. The silent question was unmistakable: Do we cut the loads and dump the water, or do we risk the beasts?

Faris gave a sharp, decisive shake of the head. Without the three hundred and forty gallons of salvaged water strapped to the twelve oxen, forty people would perish of dehydration or alkali poisoning within three days in the high limestone barrens. The water was their only leverage against the arid plateaus ahead.

Faris passed the signal down the line: Single beast interval. Handlers brace drag-lines. Hug the inside wall.

Faris took the dun bull’s halter directly. Shortening the lead to twelve inches, Faris kept the animal’s head pinned down and turned inward toward the mountain, preventing it from seeing the hundred-foot drop below its left shoulder.

Faris took the first step onto the shale span. The rock gave a faint, brittle scrape beneath their boot leather, but the clay foundation held. Faris took a second step, easing the dun bull onto the narrow bridge. The heavy bull stepped forward with deliberate care, its shoulders brushing within an inch of the bulging rock face, clearing the pinch point and planting its hooves on the wide basalt ledge on the other side of the Devil’s Rib.

Kian-dar caught the lead rope on the far side, looping it securely around a stubborn ironwood root wedged in a deep fissure.

One by one, Faris brought the pack train across. Ox Two, Ox Three, Ox Four—each beast crossed the narrow neck with muffled hooves, its water casks clearing the rock wall by inches. The survivors crossed between the animals, planting their feet exactly where Faris had trodden. Soraya-shah crossed ninth, her ironwood stick wrapped in oiled canvas, her eyes fixed entirely on the rock face ahead, refusing to look down at the jagged stones below.

Then came Ox Nine.

Ox Nine was a heavy, broad-chested roan bull carrying two forty-pound water bladders and four lashed crates of dried peas. Nevan led the beast by its nose ring from the front, while Baraz braced the rear drag-rope to keep the pack from swinging against the rock.

As the roan stepped onto the center of the shale bridge, a sudden thermal updraft roared out of the gorge, carrying a swirling gust of white alkaline dust.

The stinging powder drove directly into the roan bull’s left eye. The beast flinched with a violent jerk of its head, ripping the lead line from Nevan’s gloved grip. The left corner of the heavy ash pack frame slammed hard against an outcropping horn of limestone.

The lateral impact kicked the roan’s hindquarters outward toward the abyss.

The bull’s left rear hoof missed the edge of the shelf.

A sharp, tearing crack rang out along the scarp. A three-foot slab of the shale bridge sheared away, shattering into a cascade of sharp gray plates that fell into the void.

The roan bull let out a strangled, muffled bellow behind its tallow respirator and dropped heavily onto its belly, its hind legs thrashing in empty air. The forty-pound water bladder on the outward side pulled the pack frame down over the lip, dragging the eight-hundred-pound animal steadily toward the brink.

Nevan lost his footing on the loose scree, dragged forward onto his knees toward the edge. Behind the beast, Baraz threw his entire weight backward, digging the heels of his leather boots into the gravel as the drag-rope burned through his gloves.

Faris drew their curved carbon-steel skinning knife from their belt, the blade catching the blinding sun as they lunged across the crumbling gap. Beneath their boots, the sympathetic vibration of the cracking shelf hummed through the bedrock, shivering like a struck wire.
