“Sabotage?” Ilona asked, her voice quiet against the cold draft from the passage. Her training compelled her to weigh every archive she had ever studied against this revelation. The disaster that ruined Stefan’s standing had been deliberate. Stefan’s features hardened into sharp angles. “Not just sabotage, Lady Ilona,” he said, the words dry and even. “A betrayal. From within.” He gestured to the narrow corridor revealed by the sliding panel. “Come. The truth isn’t something I can simply articulate. It must be seen.” Ilona took a breath and stepped into the passage, stone chilling the soles of her slippers. Leaving Stefan unassisted meant watching Matei’s prospects dissolve before the winter court. The iron seam slid shut behind them with a crisp click, leaving only the amber lens of Stefan’s handheld lamp to cut the dark. The corridor opened into a circular vault, its walls lined with shelves holding aged calfskin rolls, escapement assemblies, and burnished calipers. In the center, an oak trestle bore an uncompleted bronze sphere laced with interlocking rings. The space smelled of mineral grease and copper slag. Stefan swept his lamp over a cubby, pulling free a roll tied with faded twine. He spread it flat across the trestle, holding the corners down with lead ingots. “This,” he said, tapping the draft, “is the blueprint for the celestial sphere. It was meant to track the planetary orbits through pure resonance.” Ilona leaned closer, her scribe’s eyes instantly drawn to the delicate script and precise lines. The draft displayed staggering precision, ringed with counterweights and balance springs. Yet her gaze caught on several tiny notations inked beside an energy conduit. “On the day of the collapse,” Stefan said, staring at the margin notes, “I assumed my calculations were inviolable. The final calibrations were underway, overseen by apprentices and a young Lord Joric. He spent weeks lingering near the assembly, offering unsolicited praise.” Stefan traced a finger down the inked vellum. “He lingered by the primary Kinemetal conduits, suggesting adjustments to the regulator pins under the guise of assistance.” Stefan tapped an escapement fork. “He claimed tuning the primary flux modulator would sharpen the gear train’s timing.” Ilona followed his finger. “A minor adjustment?” “On the surface, yes. Anyone studying the balance without knowing the internal tension curves would consider it sound. But it generated a slow drag against the escapement.” Stefan tapped the parchment margin. “It was built to fail during public demonstration, masking the interference as unstable resonance from my own hand.” Stefan pressed his palm flat over the ink. “The failure tore through the main power arbor and shattered the central manifold, taking my standing with it.” Ilona studied the notation. “So Joric induced the shear strain while framing your draft as reckless. It gave his faction the leverage to push your house aside.” She met his gaze. “Yet technical drafts alone will not convince the tribunal.” “No,” Stefan admitted. “We need documented transactions. After the catastrophe, two foremen left the city entirely. One of them, Hektor, oversaw procurement and logged every brass shipment.” Motes drifted in the lamp beam as Stefan sorted through rows of cloth-bound registries. Ilona moved along the lower cubbies, running a finger down calfskin spines until she located a narrow volume behind a cedar partition. “This bears your house crest,” she said, blowing away the gray dust. Stefan took the book and turned the stiff folios. “Here. Irregular drafts made out to Hektor, far beyond standard wages. And a settlement paid two days before the disaster.” He tapped a cramped mark near the tally column. “That signet belongs to Joric’s family vault.” Ilona studied the red wax impression. “Physical evidence. With this register and the technical sheets, we can draft a formal petition for the high magistrates.” A low oscillation traveled through the flagstones, followed by the distant crunch of gears from the main laboratory beyond the wall. Stefan straightened, his hand gripping Ilona’s sleeve. “That sound belongs to a heavy sentinel unit. It has no fuel cell installed.” The cycling whine rose in pitch. A dull red beam filtered through the floor seam of the concealed iron partition, accompanied by the rhythm of brass talons scraping masonry. “Its safety relays have been forced,” Stefan said. He stepped in front of Ilona, putting his shoulders between her and the seam. A jarring impact shook the iron plate as steel claws struck the exterior casing, showering sparks into the gap. Beyond the iron panel, gears screamed at maximum torque. The sentinel rammed the partition again, bucking the hinges and gouging raw grooves through the metal face as Stefan braced his weight against the shuddering frame to keep Ilona clear of the breach.
