Vashir drew his hand back instantly, breaking contact. Cool terrace wind swept across Nivem's knuckles where his palm had rested. The moment, fragile and charged, disintegrated into the crisp rooftop air. She straightened, the pretense of treating his arm a flimsy shield against the abrupt intimacy they’d shared.
“A ransom note?” Vashir’s voice was a low growl, all hint of tenderness gone, replaced by the flinty edge of command. “Give it here, Piroz.”
Piroz practically flung the parchment at him. It spiraled through the air, landing with a soft slap against Vashir’s chest. He snatched it, his gaze devouring the elegant, looping script. His jaw tightened, a muscle jumping in his temple.
Nivem watched him, a knot of unease coiling in her stomach. Whatever Omidar had written, it was clearly potent. Vashir’s eyes, usually so controlled, flashed with a dangerous, barely suppressed fury.
“He claims,” Vashir’s voice was strained, each word clipped, “that if I do not publicly confess to the Qalani Herald—confess that Zandor Industries is responsible for the Petrifying Plague in the lower districts—he will initiate a cascade failure of the main atmospheric pressure valve in the Spire’s central processing core.”
Piroz made a choked sound. Nivem felt a cold dread seep into her bones. The main atmospheric pressure valve. That wasn't just a threat to a department; it was a threat to the entire tower. To the entire district it anchored.
“A cascade failure?” Nivem asked, her voice quiet but firm, cutting through the sudden silence. “That would… destabilize the entire aerostatic foundation. The Spire would collapse.”
Vashir nodded once, a grim, sharp movement. “And everything within a three-klick radius would be crushed, pulverized by the kinetic force. Thousands dead, Nivem. Including everyone in this building.”
The words hung stark in the late afternoon. Countless citizens dead. Her ledger calculations and the quiet dream of buying back her lost greenhouse suddenly shrank to trivia beside the prospect of an urban crater.
“He can’t be serious,” Piroz whimpered, clutching at his chest. “He’s just trying to scare us.”
“Omidar is serious,” Vashir contradicted, his eyes still fixed on the note. “This isn’t a bluff. He knows the Spire’s infrastructure intimately.” He looked up, his gaze sweeping over Nivem, then Piroz. “And he wants a public confession within twenty-four hours. Or he brings down Qalani’s tallest building.”
She needed access to laboratory glassware and live specimens immediately. The personal sanctuary fund could wait; stopping an aerial detonation could not.
“Piroz,” Nivem said, her voice turning crisp. “That encrypted memo from this morning mentioned the lower ward affliction. I need everything in the filing stacks on Omidar. His personnel jacket, department postings, and archived lab notebooks.”
Piroz blinked, momentarily stunned by her intensity, but then nodded vigorously. “Right away, Nivem! Consider it done! I’ll bypass security protocols; I’m practically a ghost in the archives!” He scurried away, his earlier terror now channeled into frenetic action.
Vashir studied her, brass-colored irises narrowing. “You think he has a connection to the contagion beyond just being a victim’s father?”
“He attacked the forty-fifth floor pipeline with a botanical agent, Mr. Zandor. He deployed a targeted neutralizing resin. That is not the work of an ordinary grieving parent; it is the work of a seasoned cultivator,” Nivem replied. “He knows your processing lines intimately. I need to examine his old data.”
Less than an hour later, Piroz returned to the rooftop aerie, breathless and triumphant. He held a thick data slate, a small, triumphant smile on his face. “Found him! Omidar. He wasn’t just an employee. He was a Senior Phytologist in the Arcane Plant Science Wing. Until three months ago.”
A senior phytologist. That explained the precision of his attack. “Did he specialize in anything particular?”
Piroz tapped across the slate glass. “Yes! Here it is. His primary project was mitigating industrial effluent toxicity on magical flora. He tested bio-assimilation of runoff using resilient specimens. Specifically, the night-flowering Zatar.”
Nivem stopped breathing for a second. Her own signature perfume—the scent clinging to her skin that Vashir had pursued across the city—derived from that exact genus. A night-flowering Zatar. Its restorative sap was the singular biological agent capable of countering mineral calcification in living tissue.
“A fully mature night-flowering Zatar,” Nivem said under her breath. “That is the missing reagent. It flowers once a decade. The only viable stalks I’ve seen were held in private conservatories.”
Vashir stepped around the terrace table, fixing his gaze on her. “Private conservatories, you say?” His voice lowered. “Curious timing. The alchemical report on the woman from the Gala mezzanine identified that exact distillation. Night-flowering Zatar.”
Her collar suddenly felt stifling against her throat. No. Not here, and not over an inventory discrepancy.
“I purchased one at auction last week,” Vashir continued, watching her skin for any flinch. “A living, mature stem. It sits in my biometric vault on the sixtieth floor. Fully sealed.”
The very blossom needed to neutralize the district's petrifaction was sitting thirty yards above them, secured behind runic tumblers by the man hunting her across Qalani. To crack the biometric locks without setting off the spire's alarms would require raw botanical resonance—her resonance.
“You know how to cultivate the sap, don’t you, Nivem?” Vashir took half a step closer, the distance between them shrinking until she caught the crisp clean linen of his coat. “The vault's wards are keyed to biological resonance. An ordinary arcanist would scorch the petals trying to bypass the seal. It requires a master.”
