The throne room of the Pillar Hall smelled of unwashed wool, cold iron, and burning frankincense. Ashur-Dan did not sit upon gold; he sat upon an unworked slab of black basalt, his heavy-knuckled hands resting on the pommel of a broad, square-nosed executioner's falchion. "The girl burned three cedar screens, two silk drapes, and cracked an aqueduct feeder," Warden Ishtar said, his high, reedy voice echoing off the limestone columns. The eunuch knelt on both knees, though his eyes darted like vipers toward the dais. "Worse, Sire. When my wardens tracked her to the lower flue, she was gone. Vanished like a river mist. She carries a witch’s blight. Her brother Lugal rots from the blood-spoil, yet she walked through soot without a blister on her soles. And who hides her? The High Diviner’s acolytes closed the copper-faced gates of the North Spire in my face." At the perimeter of the dais, Azarmêdh stood with his long fingers tucked inside the embroidered sleeves of his ash-grey mantle. His face was empty of guilt, empty of defense. He merely watched the Emperor's knuckles tighten against the iron guard. "A concubine," Ashur-Dan rumbled. The sound came from deep within his chest, gravelly and scarred by years of screaming orders over dust-choked battlefields. "A nameless daughter of a border-tanner burns my inner palace, and my chief eunuch comes to me bleating about sorcery? You bring me ashes, Ishtar. You do not bring me her head." "Sire, the divination bells chimed outside the sanctum hours before the blaze!" Ishtar pressed his forehead to the flagstones. "Azarmêdh harbors a heretic! She has inverted the sacred order!" Ashur-Dan lifted the blade an inch. The iron clinked against the stone, sharp as a whip-crack. "Azarmêdh." "The woman is no witch," the High Diviner said softly. His tone carried no haste, no deferential tremble. "She is a mechanic. And unlike the Warden, she understands that iron serves the realm better than tallow candles." "Silence!" Ishtar hissed, rising onto his shins, venom pooling in his round, smooth cheeks. "Order her flayed, my Lord! Drag the sickly whelp from the lower kennels and let the dogs have him before her eyes! The law of the Gilded Cage cannot bend for—" The heavy cedar doors at the hall’s southern threshold groaned. Heads turned. Four mute laborers in charcoal wool trudged through the opening, dragging a wheeled platform plated in boiled leather. Upon it rested the Sky-Harbinger. The rust had been scraped clean, replaced by the reek of rendered lard and vinegar. Polished brass counterweights gleamed like dull gold under the torchlight. Springs of tempered spruce, bound in braided cord, hummed under tension. Walking directly behind the siege engine, her hands smeared with black tallow grease and her linen tunic cinched tight with a boiled-leather belt, stepped Ninsianna. Her step was measured. Thirty-two inches per stride. Chin level. Eyes front. She did not lower her gaze to the floor, nor did she flinch when fifty imperial halberds shifted in unison toward her throat. "You," Ashur-Dan said. His gaze flicked over her ruined garments, stopping at the blackened soot stained into her hairline. "The fugitive." Ninsianna halted five paces from the dais. She dropped to one knee, but kept her head upright, locking her gaze directly onto the Emperor’s broad, scarred nose. In her previous life, she had faced down tribunal generals with fewer bloodstains on their tunics; Ashur-Dan was simply an artillery officer who had won his crown with brute force. "I am Ninsianna, of the lower courts," she said, projecting her voice from her diaphragm so it sliced cleanly through the humid gloom. "I did not flee to save my skin. I fled to salvage your artillery." A collective gasp rustled through the gathered scribes and harem overseers. Ishtar leaped to his feet. "Impudent dog! She speaks without leave! Guard—" "Hold," Ashur-Dan barked. His dark eyes narrowed, darting from Ninsianna's steady face to the intricate brass contraption beside her. "The Harbinger has not sung since my grandfather died beneath the walls of Qatna. Three master artisans from the western gulf lost their ears trying to align its gearing. You claim you solved it in a night?" "The apparatus was never broken, Sire," Ninsianna stated, rising without waiting for permission. She stepped to its flank, slapping her palm against a heavy iron crank. "It was jammed because your artisans treated ballistics like an act of prayer. They oiled the pinions with tallow, which rotted and seized the differential. They assumed the arc of fire was a straight incline governed by the gods." She seized a square-headed iron key and shoved it into the brass housing. With a savage twist, she engaged the spring. A rapid, metallic chatter—*clack-clack-clack-whirrr*—erupted from the engine's chest. Cogs clicked into alignment with terrifying precision. An articulated arm of jointed timber and iron swung upward, snapping to a forty-two-degree angle with a crack that set the guards back a step. Ninsianna pointed to a brass plate inscribed with three sliding scales. "The northern frontier is plagued by the Grey Creep. Husks do not tire; they charge through marshes and ravines where standard catapults cannot guess the drop. This apparatus does not guess. Input the elevation of your battery. Input the estimated wind shear from the valley drafts. Dial the counterweight ratio here." Her fingers danced across three iron pegs, setting the values with ruthless speed. She yanked the secondary trip-cord. The gears screamed, spinning in a blur of interlocking brass. A calibrated pointer along the lower quadrant swung across the brass arc, coming to an abrupt, violent stop against a notched pin. "Five hundred and ten paces," Ninsianna declared, her voice flat, cold, and absolute. "Load an eighty-pound iron sphere, burn twelve ounces of black pitch at the base, and release. It will clear the parapet of a siege trench at eighty cubits and strike within a five-yard radius every single time. Rain, mist, or dark. It removes the human error from slaughter." Silence fell over the hall. It was absolute. The muttering of the scribes ceased entirely. Ashur-Dan stood up. He left his great iron sword leaning against the black basalt throne. He descended the three stone steps, the heavy rings on his boots ringing out on the marble, until he stood less than two paces from Ninsianna. He smelled of sweat and old leather. He looked at the spinning governor, then down at Ninsianna’s grease-stained hands. "You lie," the Emperor whispered. "Place a target at the far end of the outer yard," Ninsianna said, not giving an inch of ground. "Hang a commander's standard from the parapet. Load a dry stone. If the stone misses by more than a man’s breadth, have Warden Ishtar take my skin. But if it hits, you admit that science trumps superstition." Azarmêdh tilted his head, a ghost of an amused smile playing at the corners of his lips. Ishtar’s jaw worked soundlessly, his face mottled with purple fury. Ashur-Dan stared at her for ten agonizing seconds. Then, a low, rasping rumble escaped his throat. It grew into a full-throated roar of laughter that shook the torches in their brackets. "A concubine who talks like a siege engineer!" Ashur-Dan struck his own thigh with a massive fist. "By the gods of the dirt, the Spire has produced something useful at last!" He spun around, fixing Ishtar with a look of predatory scorn. "Ishtar! You wanted her whipped for an apron-full of burned silk? You idiot. She has handed me the key to reducing the stone citadels of the northern lords before the freeze." Ishtar fell back to his knees, his hands trembling against his silk skirts. "Sire... she... the laws of the harem..." "The harem exists to serve my empire, not to rot in perfumed boredom," Ashur-Dan sneered. He turned back to Ninsianna, his eyes burning with an intense, covetous hunger. Not the hunger for flesh—he had five hundred women for that—but the hunger of an autocrat who had just seen a weapon that could preserve his bloodline. "Name your price, girl. Silk? Rubies? The rank of Lady of the Third Basin?" Ninsianna did not blink. "Keep your stones, Emperor." The scribes drew in their breath at the blunt refusal. "I want two things," Ninsianna said, her tone level and unyielding. "First, absolute custodianship over the lower vaults of the Imperial Library—specifically the logistical ledgers, trade maps, and cartographical surveys of the northern marches. Second: Lugal is to be taken from the lower quarters immediately. He will reside in my personal suite in the East Pavilion, guarded not by harem eunuchs, but by four of your own Iron Guard, answering only to my command." Ashur-Dan’s eyes narrowed into slits. His paranoia, never asleep, twitched behind his brow. "You ask for military records. And royal guards for a dying tanner's whelp." "I ask for the tools to calibrate more siege works for your army," Ninsianna countered instantly, parrying the suspicion before it could take root. "And I ask for the safety of the only kin I possess. If Lugal dies of neglect while I rebuild your war engines, every gear will stop turning." A dangerous tension hung in the air. For a breath, it seemed the Emperor might draw his blade and cleave her where she stood for her insolence. Then he spat on the floor. "Granted," Ashur-Dan decreed. "The East Pavilion. The keys to the lower maps. But hear this, Ninsianna: if the Grey Creep breaches the Red Sluice before the autumn moons because your calculations faltered, Lugal will be thrown into the beast-pits while you watch." "He will not die," Ninsianna said. "And neither will your borders." Ashur-Dan turned his back and strode up the dais, already shouting orders to his quartermasters to haul raw ore to the foundries. Ninsianna stood motionless as the court erupted into chaos. Across the flagstones, Warden Ishtar slowly rose from the floor. He did not look at the Emperor. He looked straight at Ninsianna, his lips peeled back from his teeth, his pale eyes burning with a venom that no clockwork engine could measure.
