I forced myself to look past the blinding light, focusing my senses, pushing through the pain barrier with the breathing techniques Mateha had taught me. Three short inhales, one long exhale. Center. Filter. Analyze. Slowly, painfully, the chaotic visualization began to resolve into something marginally coherent.

"It's... the core matrix," I managed, describing the patterns forming in my mind. "A massive crystalline structure... fractured. Badly. It's pulsing erratically, sending out waves of raw, unstable energy."

I could see the feedback loop now with terrifying clarity—energy surging, overloading, feeding back into the damaged core, amplifying the instability with each cycle.

"And conduits... huge power conduits... one is glowing critical red. It looks ready to rupture."

The sheer scale of the power contained—and failing—within that chamber was staggering. It dwarfed the control terminal, dwarfed even the Harmony Circle. This was the heart of the ancient machine, and it was dying violently.

"The warning glyphs," Iros noted grimly, his eyes fixed on the complex symbols carved around the massive doorway. "Extreme energy hazard. Unstable containment. Neurological disruption." He paused, his voice dropping. "Sacrifice."

The final word hung heavy in the superheated air. Sacrifice. What had the ancient Nyxari meant? Sacrifice of the operator? Sacrifice of the facility itself to contain a greater catastrophe? The ambiguity was chilling.

"We knew the risks," I said, meeting Iros's intense golden gaze. Fear was a cold knot in my stomach, but looking at him, seeing the shared determination in his eyes, somehow made it bearable. The memory of last night, the intimacy we shared, was a tangible warmth against the fear, a reminder of what we were fighting to protect—not just the Aerie, but the possibility of a future.

"Nirako, Pravoka," Iros addressed the Aerie warriors. "Secure this antechamber. Watch for any further automated defenses or structural collapse. Allow no one and nothing to interfere once we begin."

The two Nyxari nodded curtly, their faces grim but resolute. They moved to flank the doorway, spears held ready, their loyalty absolute despite the obvious terror this place inspired in them.

"Jen," Iros turned back to me, his hands gently gripping my shoulders, forcing me to meet his gaze. "What I am about to ask of you... it is beyond what anyone should face."

I sensed his internal conflict—his duty, his knowledge that I was the only key, warring with his need to protect me from this danger.

"Are you certain you can do this? There is no shame in turning back."

I looked past him, towards the pulsing red inferno visible through the doorway. I thought of Rokovi's madness, of the Aerie children facing starvation if the Shardwings couldn't hunt, of the potential for this failing system to shatter the entire mountain range. I thought of the future we might build, human and Nyxari, if we survived. And I thought of the connection between us, the strength I drew from him, the trust he placed in my abilities.

"I'm terrified," I admitted honestly, my voice trembling slightly. "But I saw the stabilization protocols on the terminal. I know the counter-harmonic sequence."

I met his gaze, finding my resolve. "And I know that if we do nothing, the consequences will be far worse. We have to try, Iros. I have to try."

He searched my face for a long moment, then nodded slowly, accepting my decision, though the worry in his eyes didn't lessen.

"Then tell me what you need from me. How can I help create the opening you require?"

We stepped closer to the doorway, peering into the core chamber itself. The sheer scale was massive. The fractured crystal matrix dominated the center, suspended within a web of energy conduits, pulsing with that angry red light, radiating intense heat. The roar of power was deafening. Smaller crystalline structures—regulators, buffers, capacitors perhaps—were scattered around the core, many shattered or dark. The overloaded primary conduit I'd sensed pulsed visibly, the metal casing glowing cherry-red, clearly under immense strain.

"The feedback loop," I explained, shouting slightly to be heard over the roar, pointing towards the core. "It's cycling energy back into the fractured matrix faster than the damaged regulators can handle it. That's causing the overload, the dissonant broadcast."

I focused, visualizing the energy flows. "The counter-harmonic sequence needs to be introduced directly into the core interface—that crystalline hemisphere on the control platform beneath the matrix."

I indicated a raised platform by the base of the core structure, upon which rested an interface terminal similar in design to the one in the control room, but larger, more complex, and currently bathed in the core's unstable energy.

"But the feedback intensity... it's too high," I continued. "Connecting now would be like... sticking my hand into a sun. My markings would be overwhelmed instantly. We need to disrupt the feedback cycle, even for a few seconds, create a window of reduced energy flow."

Iros followed my gaze, his tactical mind assessing the physical components.

"That primary conduit," he said, pointing to the one glowing critical red. "It feeds the core directly. If I could temporarily divert its power flow, or dampen its resonance using the harmony stones..."

"Yes!" The idea clicked instantly. "Dampen the resonance! The stones reacted so strongly to my markings, to the Harmony Circle. If you place them at key junctions along that conduit," I traced the path with my finger, visualizing the energy nodes, "they might absorb some of the chaotic energy, create a localized harmonic field that disrupts the feedback loop momentarily."

He studied the conduit, the surrounding structures, calculating angles, risks. "The heat is intense. The energy discharge risk, extreme. But it might be possible." He looked at the harmony stones Nirako still carried. "We have six stones. Where should they be placed for maximum effect?"

I closed my eyes, extending my senses, visualizing the chaotic energy flow along the conduit, searching for the points of maximum dissonance, the nodes where a counter-harmony would have the greatest impact.

"Three points," I determined finally, opening my eyes and indicating specific junctions. "Two stones at each point, placed simultaneously. It will create a brief harmonic resonance shield, interrupting the primary feedback surge."

"How brief?" Iros asked, his gaze sharp.
