A bitter fog rolled off the canal basins at dawn. It curled through the broken brickwork of Slum Ward 9.
Inside the warehouse, the fire had burned down to glowing birch embers. Arthur woke to the metal cold of the sub-basement air. Beside his camp cot, Toby Mallow was already stirring, lighting an animal fat candle with shivering fingers and pulling his wool coat tight.
“Arthur,” Toby whispered, his breath puffing white in the candle flame. “Look at the chimney.”
Arthur sat up. In the far corner of the hall. There, the sixty-foot brick chimney pipe met the western wall, stood Grimm.
The fifty-two-pound jet-black hound was standing motionless in a ninety-degree angle. His broad, square nose was pressed firmly into the mortar seam. His eyes buried in was dark brickwork, his tail tucked tight against his hocks. He stood rigid, resembling a statue of fiery dark rock.
Beside the workbench, Toby’s canvas knapsack lay overturned. A paper wrapper that had held two dried beef biscuits lay shredded across the floor, licked spotless.
“Hungry mental shifted weight,” Arthur murmured, swinging his legs over the cot.
Toby pushed his glasses up his nose, squinting at the dog. “He stole my breakfast, Arthur. Then he shoved his face into a brick corner so he wouldn’t have to look at me.”
“In his mind, if his eyes are buried in the stonework and he can’t see you, then you can’t see him either,” Arthur said. He pulled on his boots. “It’s a gut shame reaction. He knows he breached domestic boundaries, but his old family territorial pride forbids begging on their knees. So he makes himself invisible.”
“He’s fifty kilos of black fur in an empty room,” Toby muttered. “He’s about as invisible as a locomotive.”
Toby picked up the wrapper, walked over. Then he dropped a crust of dry bread onto the stones behind Grimm’s rear paws. “You’re a thief, mutt. But it was stale anyway.”
Grimm didn’t move for ten seconds. Then, with painful slowness, his left ear swiveled backward toward the bread. The hound backed out of the corner with silent steps, vacuumed the crust with one flick of his tongue, and right away lay down across Arthur’s boots, resting his heavy chin on the leather toes.
Arthur rested a hand on Grimm’s muscular scruff. The dog’s coat was dense, the underlying bone structure solid.
A sharp, clamorous rattle shook the iron courtyard gate.
It sounded like an angry crowd hammering iron bars with wrenches, with the cries of frightened animals and shouts of men.
“Guards?” Toby asked, his hand flying to his ledger box.
“No,” Arthur said, feeling the shakes through the soles of his boots. “Guards don’t bring animals in distress.”
Arthur pulled the heavy door open and stepped into the freezing fog.
The muddy courtyard was packed from wall to wall. More than forty people stood outside the gate. Coal haulers, town drain cleaners, rag collectors, and canal bargemen, their oilskins coated in gray frost. And beside almost every worker stood a beast.
There were wire-haired sewer terriers used to clear vermin from stormwater chimney pipes. Heavy scrap hounds that pulled iron hand-barrows. And stunted heavy cart ponies with matted manes.
Every single animal was in acute body distress.
A town drain cleaner stepped forward, clutching a shivering sewer terrier. “Master Vance! Word reached the South Pumping Station about Old Rusty. You have to look at Nip. His mouth won’t stop bleeding, and his paws are falling apart!”
“My pony collapsed three blocks from the depot, master!” a wagon driver shouted. “Her legs are stiff as pine, and her skin is peeling off in sheets!”
“Bring them inside,” Arthur commanded, swinging the gate wide. “Toby, open the holding pens. Light the second hearth. We need boiling water and clean cloth.”
The hall filled rapidly with coughing animals, wet boots, and anxious voices. Arthur stood at the three-ton zinc slab, snapping on rubber gloves.
“Form a single line along the eastern wall,” Arthur projected his voice with razor-sharp power. “Toby will take your names, beast species, and ration sources. Keep larger beasts tied to wall rings. No shouting.”
Arthur lifted the first patient onto the zinc slab—the wire-haired sewer terrier named Nip.
The little hound weighed twelve pounds, racked with spasmodic tremors. When Arthur parted the dog’s lips, the stench was appalling. The gingival margins were swollen, spongy, and weeping dark blood that failed to clot. Several premolars were loose in their sockets, rocking under light touch.
He examined the paws. The horn-protein of the claws was dry, brittle. Then he cracked down the center, exposing raw, inflamed blood-vessel tissue beneath. The terrier’s coarse coat came away in Arthur’s fingers in greasy clumps. That left pale, leathery skin covered in white flakes.
Arthur slid his fingers down the terrier’s inner thigh to palpate the main thigh blood vessel and the next-door superficial mana channel.
Instead of the supple, elastic vessel of a healthy Iron-Rank beast, the channel felt like a stiff copper wire. The blood-vessel wall was hard, rigid, and crusted with gritty stone deposits.
“Mana-vein turning to stone,” Arthur murmured.
Beside the table, Toby recorded findings with a trembling hand. “Arthur, three more handlers report matching symptoms in their scrap hounds. Loose teeth, cracked claws, and hair loss. Is it a plague from the deep rifts?”
“Plagues are specific to taxonomic families,” Arthur replied evenly. “A viral bloody fever infecting canines doesn’t at the same time attack the blood-vessel systems of equines and burrow-hogs. Look at the pony tied to post four.”
Arthur walked to the heavy cart pony. The animal stood with head hanging low, knees locked, thick spit dripping from swollen gums. Its hooves were split along the coronary bands, breath shallow and rapid.
“Matching sickness,” Arthur said. “Systemic blood-vessel breakdown, horn-protein dystrophy, and outer channel turning to stone across three distinct mammalian orders. This isn’t an infection. It’s a body-energy toxin.”
Arthur returned to the zinc slab. With a quick nick of a brass lancet to the terrier’s ear margin, he collected two drops of dark tiny blood vessel blood onto a quartz slide.
He flipped his jeweler’s monocle over his right eye, focusing spiritual intent into the living assay.
The world pulled back into micro-cellular clarity. Through the lens, the red blood cells appeared abnormal—shrunken, crenated, membranes crumpled like withered leaves. Floating in the clear star-fire were millions of needle-sharp crystal-clear precipitates, tumbling through fluid and shredding endothelial cells.
An amber test frame locked across his vision:
Arthur’s eyes narrowed.
Ingested quarry lime and man-made white spar-stone.
The test slate confirmed what his cold and exact instincts suspected. The beasts were suffering from acute, systemic phosphate depletion driven by an overwhelming surcharge of heavy-duty white lime-chalk.
Every mammalian engine needed a delicate balance between calcium and phosphate. An animal ingested massive quantities of insoluble bitter-salt chalk. Then, the bitter-salt load stopped gastric acid, destroying the stomach’s ability to break down proteins.
Worse, excess free calcium bound dietary phosphorus in the intestine, forming insoluble calcium phosphate salts that were excreted in dung. Starved of bio-available phosphorus, the animals’ cells couldn’t synthesize adenosine triphosphate—the chemical fuel for mitochondrial breathing.
Deprived of cellular energy, connective tissues failed. Connective tissue production collapsed, causing gums to bleed and teeth to loosen. Horn-protein synthesis halted, cracking claws. And to clear circulating stone excess, their bodies deposited jagged white spar-stone crystals directly into the elastic walls of mana channels.
It was a heavy-duty scurvy, engineered by chemical adulteration.
“Kael!” Arthur called out, spotting the old wagon driver standing near the entrance holding Old Rusty’s lead. “Come here.”
Kael hurried over. “Yes, Master Vance?”
“What did you feed Old Rusty before he broke down two days ago?”
“The same thing everyone feeds their beasts in Ward 9, master,” Kael said. He pointed to a burlap sack slung over a wagon driver’s shoulder. “Vanguard Town Ration Pellets. The Grade-A working mix from the spreading depot. Thirty copper tokens for a fifty-pound sack. Private mills charge three silver coins for whole oats, so nobody in the slums can afford anything else.”
Arthur stepped to the wagon driver holding the sack. “Open it.”
Arthur reached in and pulled out a handful of the commercial feed.
The pellets were dull gray and chalky. He smelled faintly of rancid pork lard that masked an acrid stone odor.
Arthur walked to the shelf, uncorked a vial of packed acetic acid. Then he crushed two pellets into a baked-clay saucer. He poured three drops of acid over the powder.
The crushed pellet erupted into a violent, frothing boil, releasing dense clouds of carbon dioxide and leaving behind a gritty sludge of insoluble sand and crushed limestone.
Toby stared at the bubbling dish, eyes wide behind his glasses. “It’s effervescing! Feed shouldn’t boil when you add vinegar!”
“Feed shouldn’t contain seventy percent powdered limestone,” Arthur said, his voice cold. “Real working beast rations are made from steamed bone meal, rolled barley, and rendered fat. Bone meal is rich in organic calcium phosphate, which draft animals need to maintain dense bone and conduct mana through their channels.”
Arthur crushed another pellet, feeling the gritty grit of quarry tailings.
“Someone replaced the organic bone meal with heavy-duty lime, quarry dust, and slaked chalk,” Arthur continued. He turned toward the silent workers. “They sprayed it with just enough rancid fat to fool the animals into eating it. The chalk stopped their stomach acids and leached usable phosphate from their skeletons. Their cells are choking from the inside out.”
A collective gasp echoed through the hall.
“The academy depot is poisoning our beasts?” the drain cleaner cried, clutching his bleeding terrier.
“Not poisoning to kill,” Arthur replied grimly. “Poisoning to steal. Quarry dust costs three coppers a ton at limestone pits. High-grade bone meal sells for forty silver tokens a sack to high-born breeding stables in Sector 1. Whoever runs the Ward 9 depot is skimming the nutritional core from the town supply, pocketing hundreds of thousands of credits, and feeding your animals construction waste.”
Toby grabbed the burlap feed sack. That turned the coarse fabric toward the lantern light to inspect the blue stenciled lettering across the weave.
His face went pale.
“Arthur,” Toby whispered, his knuckles whitening against the burlap. “Look at the shipping stamp.”
Beneath the faded seal of the Vanguard Town Board was a crisp corporate mark. A winged griffin perched atop an iron vault.
“Crestline Agricultural Logistics,” Toby read, his voice trembling with fury. “That’s Dean Horatio Pendelton’s private shell company. The same Pendelton who sat beside Gregory Vance in the VIP box yesterday.”
Arthur looked across the hall at the dozens of shivering dogs, weeping ponies, and scared workers.
“Pendelton,” Arthur said softly. His fingers tightened around the cold zinc rim of the cutting-open table. “He didn’t just try to steal my family charter. He’s starving an entire district to line his pockets.”
Grimm rose from Arthur’s boots, his black glass fur bristling along his spine, a low, earth-shaking growl rumbling from the depths of his chest.
