Marrow in the Mud

A warm drop struck the crown of Tobechi-adu’s reed hat with the hiss of frying fat, eating a clean, smoking circle through the dried river grass. Beneath the rim, he tilted his ear upward into the white blindness of the fog, counting the hollow splatters that followed across the black silt. Something heavy had dropped from the Seventh Rib three hours past, cutting through the updrafts before the leeches caught it, and Tobechi-adu meant to reach the impact hollow before the afternoon updrafts dispersed the marrow fumes across the canyon floor.

He planted his bamboo stilts four feet into the grey mud, leaning forward to keep the broad baskets of his boots from seizing in the river silt. Eight hundred feet above, invisible behind three layers of curdled cloud, the great spine of Ozu-Eke spanned the gorge. Down here, the world was cold tallow, decaying reeds, and the steady, sulfurous drip of ancient vertebrae weeping into the dark.

A second drop landed on his shoulder mantle of boiled ox-hide. The hide hissed, turning pale yellow around the splash, but the wax held.

Tobechi-adu reached into the wicker creel strapped to his breast and uncorked a gourd with his thumb. The grease in the air tasted of copper filings and lye. Normally, what fell from the span was harmless limestone dust, dried mule droppings, or the watery vinegar of superficial frost-rot. When the marrow ran hot enough to singe hide, it meant an axle was grinding directly against an unpinned joint. It also meant money in the lower villages, where smiths paid six copper pence a dram to temper scythe-blades in beast-grease.

He dragged his left stilt free of the sucking bank with a wet pop. Ten paces ahead, the grey reed beds lay flattened in a radial blast.

The crater was six yards across, filled with boiling, milky water that smelled of scorched brass and scalded hair. The force of the drop had driven whatever fell two cubits deep into the silt, leaving only a froth of scum and shattered rushes around the lip.

Tobechi-adu halted his stilts at the margin of the pool. He reached to his hip for his ash-pouch, uncinched the hemp drawstring, and flung three handfuls of charred sheep-bone into the steaming water.

The bone-ash bit the grease with a crackle like burning brushwood. White curds separated from the murk, floating to the perimeter in waxy disks. That was the trick to the canyon floor: let raw marrow sit in stagnant water and it bred skin-rot within an hour, but dust it with lime and bone-ash before the air cooled, and the poison settled into usable fat.

He knelt upon his woven leg-pads, unhooking his wide horn ladle.

In the center of the pit lay the steaming sediment of the fall.

Whatever human had dropped had been swallowed whole by the swarm eight hundred feet above, his flesh and iron gear devoured mid-air into the gaping maws of the leeches. But the parasites could not digest southern bronze; refusing the alloy of copper and tin, the swarm had spat out a heavy armlet, and its plummeting weight had dragged down a trailing wad of regurgitated bile and undigested iron dross through the fog. Only curdled grey froth and porous slag remained in the crater, hissing faintly where the acid gnawed into the river silt.

Highborn constables from the southern provinces paid fortunes for embossed carriage harness and guild-stamped steel, Tobechi-adu reflected, only for an eighty-foot downdraft to feed it to the canyon floor as caustic froth for peasant scythes.

He reached with his horn ladle toward a puddle of uncurdled fluid pooling in a depression of molten slag. The fat there gleamed with an oily violet sheen, clear of reed-grit.

Before the ladle touched the liquid, the sludge in the hollow shifted.

A cluster of segmented white bodies boiled out of the grey broth. They were not the common canyon grubs that scavenged drowned goats—these were finger-length, ribbed in pale horn, and possessed of five-ringed mouths ringed with needle-like calcium teeth. Their skin was translucent, showing the bright, curdled marrow pulsing through their bellies in rhythmic spasms.

Tobechi-adu froze, resting his weight back on his heels.

There were forty of them, packed tight in the boiling depression. Common leeches lived solitary in the wet fissures of the under-ribs, sluggish from centuries of cold mist. These moved with a frantic, communal purpose, weaving between each other like maggots in a sun-ripened carcass, their tails anchored in the dense marrow scum at the center of the pit.

One of them reared its blunt snout toward the damp salt of his skin.

Tobechi-adu reached for his pouch of salted sulfur, but the creature did not recoil from the yellow powder. It launched itself across the water, hitting the woven wicker of his chest creel with the dull thump of a thrown pebble.

The impact jarred his ribs. He dropped the ladle and seized his horn scraping-knife, slashing down across the wicker. The blade sheared through the creature's tail, squirting yellow slime across his knuckles.

A second leech sprang from the mud before he could recover his balance.

It struck his left wrist, slipping past the boiled-hide cuff where his skin was wet with sweat. Its tooth-ring bit deep into the meat above the tendon before he could drive his thumb into its soft neck.

A blinding cold tore up his arm.

It was not poison. The marrow entered his blood like an iron spike driven through ice, freezing the pulse in his throat and turning his vision white.

In that frozen split-second, his mind left the canyon mud entirely. He felt the terrifying, vast weight of an arched sky, the crushing pressure of six leagues of mountain granite, and three hundred iron stakes driven through the living ligaments of his back while his jaws were pinned shut with river silt. The creature had never been slain. It had only been staked into the rock while it slept, smothered under millions of wagon-wheels, its living spine calcified by centuries of mortal lime and mortar.

The beast was not dying of age. It was waking beneath the harness.

The shock flung Tobechi-adu backward into the reeds. He gasped, his lungs burning on the sulfuric fog, and fell hard against the roots of a wild willow.

His left arm throbbed with a dull, leaden ache. The dead leech lay limp on his forearm, its segmented hide deflated, having emptied its marrow into his vein before dying.

Tobechi-adu tore the carcass from his flesh with his teeth and spat it into the water. The wound wept clear, viscous fluid that did not mix with the blood running from his thumb.

He sat in the crushed grass for several breaths, his chest heaving, the canyon silence ringing in his ears like struck bronze.

Above the mist, far out of sight, a dull rumble traveled down the rock. It was the heavy, shuddering groan of iron axles grinding across bone, followed by the faint chime of church-bronze bells from the northern tollhouse.

Tobechi-adu looked down at the steaming depression. Half-submerged in the grey foam, resting upon the porous iron slag, lay a broad bronze armlet. It bore the raised crest of the Southern Duchy—a horned bull trampled by iron chains—unpitted by the acid because its alloy was copper and tin, untouched by marrow-rot.

He reached forward with the tips of two fingers, plucked the armlet from the scum, and wiped it against his thigh. Then he unstoppered his two remaining clay gourds, skimmed the violet grease pooling in the hollows of the molten slag, and sealed the corks with river mud.

The villagers in the low settlements thought the bridge was eternal stone, a gift from ancient ancestors who had tamed the sky. They bought his tallow to grease cart-wheels and light lamps.

Tobechi-adu pushed his stilts back into the grey sludge and turned his face toward the massive, mist-shrouded pilings of the northern abutment. He had two gourds of living marrow at his belt, a southern duke’s bronze in his creel, and an iron agony still humming in the marrow of his own arm. He would not sell this fat to the smiths. He had to climb the ribs before the waking beast broke its tether.
