Brine churned at Tahirih’s knees, thick with black trench-bile. Kivanc’s weight nearly drove her under. He was solid iron and dead mass, his chest weeping thick indigo poison from the barb wound. "Keep your feet," she hissed at him, though his head hung limp against her clavicle. "Stand, damn you." He gave no answer save a wet, rattling gasp. The Kasir’s lower gallery groaned beneath three hundred fathoms of sea-pressure; the ward-lines groaned with the sound of snapping bronze cable. Tahirih caught Kivanc beneath the armpits, hauling him backward through a pressurized bulkhead into the south stairwell. Mizrak darted ahead, his spine-tail stiffened into an arched quill, his claws clicking on wet flagstones. The beast leapt against a lead-weighted valve, throwing his diminutive body onto the release lever. With a hiss of suction, the bronze hatch swung inward, admitting them to the conservatory. Here, the estate’s upside-down gravity took hold. Up was down. The glass dome formed a bowl beneath their feet, looking out into the sunless trench where luminous leviathans glided through pitch-black water. Suspended above them hung inverted beds of night-blooming belladonna, black orchids, and moss beds steeped in damp peat. The air smelled of loam, crushed mint, and the sharp tang of ozone. Tahirih dropped Kivanc onto a bed of crushed ferns. His skin had taken on the curdled grey of sea-foam. The venom-barb had pierced three inches below his collarbone, missing the artery but pumping trench rot straight toward his pericardium. Black veins branched across his pectoral muscle like lightning strikes. "Look at me," she ordered, ripping his soaked silk doublet down the center. Buttons scattered across the glass floor like hail. "Kivanc. Focus." His eyelids lifted by a fraction. The illusion on her face was gone, washed away by the tide and burned out by her casting. Her true features—high cheekbones, smooth olive skin untouched by fire, lips parted in fierce concentration—were laid bare under the eerie bio-luminescence from the deep outside. He didn't speak. He couldn't. His teeth clicked together in a violent tremor. Tahirih sank to her knees straddling his hip, pressing both palms flat over the puncture. She didn't bother hiding her craft anymore. Paranoia screamed at her to flee, to slip through the drainage ducts while he died and take her freedom with both hands. But the binding in her chest pulled like a fishhook set in raw meat. If his spark went out, the rebound would tear her mind to ribbons. *Not for you,* she told herself, gritting her teeth until her gums bled. *I am saving my own skull. Nothing more.* She plunged her consciousness down into the wound. Her power wasn't a gentle salve; she was a shadow-weaver, forged in the soot-alleys of the canal districts where thieves lived on stolen breath. She gathered the dark fluid pooled around his ribs, knotting it into needles of solid void. She hooked the needles into the foreign venom, pulling slowly, steadily, dragging the toxic slurry out grain by grain. Kivanc arched his back, a strangled howl tearing from his lungs. Blood bubbled between his lips. "Quiet!" she snapped, digging her knees into his hips to pin him to the earth. "Take it. You survived an arch-fiend, you bastard, don't choke on a mouthful of bile now!" Ink-black droplets rose from the hole in his chest, hovering in the zero-gravity eddies between their faces. Tahirih caught the globes of venom with a flick of her wrist, condensing them into a dense, marble-sized orb of dark glass, then threw it against the floor, where it cracked into harmless dust. His breath caught in a dry wheeze, then slowed. The grey hue receded, leaving his skin pale as salt. Tahirih leaned back, panting, wiping salt-crust from her forehead. Her muscles burned from the strain. Then, a low sound broke the silence. A dry, ragged rasp. Kivanc was laughing. She stiffened, reaching for the dagger at her boot. "Have you lost what little sense you had?" He lay flat on his back, staring up at her with unfocused, fever-bright eyes. His gaze traced the arch of her brow, the line of her jaw, the unmarked curve of her neck where the burn disguise had vanished completely. "I knew," he murmured, his voice slurred with fever. His chest hitched as another cough racked him, but the crooked grin stayed on his lips. "You knew nothing. You were blind." "The ash-scarred daughter of House Danis," he whispered, blood speckling his bottom lip. "Her hands were always too steady. Her stride never hesitated in the dark. I had my scribes check the records three times. The burns were supposed to have melted the tendons in her right arm. But you... you poured tea without a single tremor." Tahirih froze, her ribs tightening. "You knew she was dead?" "I knew the creature living under my roof was an impostor. A spy, perhaps. A mercenary waiting for my throat." He lifted his head an inch, his gaze burning through her like hot tallow. "So I drafted the divorce. To throw you out before you put a blade through my ribs. To keep my hands clean. But I never... by the drowned gods, I never dared hope." A terrible stillness descended upon the greenhouse. "Hope what?" she asked, her voice dropping to a knife-edge. "That the viper pretending to be my meek wife..." Kivanc reached up, his knuckles grazing her chin, firm and cold, "...was the same phantom who bled me dry upon the silk sheets and vanished into the rain." Tahirih knocked his hand away with brutal precision. "You speak nonsense. The poison has scrambled your brain." "The scent doesn't lie, my sweet thief. Even beneath sea-water. Bitter myrrh." Before she could draw her dagger to settle the argument, Mizrak let out an ear-piercing shriek. The glass dome above them exploded. Shards the size of broadswords rained downward, whistling through the gravity-well. Tahirih threw her cloak over Kivanc instinctively, her cloak hardening into an umbrella of solid shade as heavy glass pelted the fabric like hail. Six figures dropped through the breach, suspended on thin wire-lines. They wore the lacquered, segmented carapace of rival executioners—the Iron Hydras. In their gauntlets, heavy cross-pikes gleamed with rune-light designed to sever magical conduits. "The Lord-Exarch is bleeding!" the lead killer called out, boots hitting the soil with a muffled thud. "Take his head! Our patron pays double if the woman’s tongue is intact!" They didn't look at her face. To them, she was just the useless bride cowering over a dying master. Kivanc struggled to rise, pushing up on one elbow, his teeth bared in fury. "Tahirih, get behind—" "Stay down, you idiot," she said softly. She rose to her feet. The meekness, the hunched posture of the disgraced bride, the timid downward tilt of her chin—she discarded them all like an old snakeskin. Tahirih opened her arms. The shadows pooled beneath the inverted flower beds did not simply stretch; they tore. Ribbons of razor-sharp void erupted from the glass floor, blacker than the abyssal ocean surrounding them, shrieking through the air with the sound of shearing metal. The lead assassin raised his pike to parry. Her strike cut through the steel weapon, through his brass armor, and through his ribcage in a single clean crescent. He was dead before his boots left the moss. The remaining five barely had time to reset their footing. Tahirih swept forward, moving with the terrifying, fluid grace of a creature born in bottomless depths. A lash of compressed dark snapped out, wrapping around two necks and snapping them with a sharp double-crack. The third raider lunged with a venom-spike; she stepped inside his guard, caught his wrist, and twisted until bone splintered through leather, driving his own blade through his visor. The final two tried to engage their wire-lines to flee back up through the shattered dome. Tahirih clenched her fist. The shadows under their boots rose like living pitch, dragging them down into the soil, snapping their spines against the floorboards before they could scream. Silence fell over the greenhouse, save for the patter of falling seawater through the open roof. Six corpses lay steaming in the cool air, butchered in less than four breaths. Tahirih stood amidst the carnage, her sleeves drenched in gore, the lethal vortex of her magic slowly settling into long, hungry ribbons around her boots. Her chest rose and fell in jagged rhythms. Slowly, she turned around to retrieve her cloak. Kivanc was sitting upright against the bench, fully conscious, the fever gone from his eyes, watching her with a hunger that made the trench beasts outside look tame.
