As the hidden entrance to the Aerie settlement came into view, I felt a palpable shift in the atmosphere compared to our previous arrivals.

A small crowd had gathered, led by Mateha, her weathered face etched with anxious hope. Word of our return, and our success, must have somehow preceded us. The suspicionthat had greeted us initially was gone, replaced by desperate anticipation.

"You return," Mateha breathed as we reached the entrance, her gaze immediately locking onto the carefully wrapped bundles we carried. "And you bring the mountain's heart-song back with you."

"We retrieved six stones, Healer," Iros reported formally, though relief and satisfaction resonated from him. "The Depths were unstable. The Lurkers have multiplied. Pravoka is injured."

Mateha's attention immediately shifted to Pravoka, her healer's instincts overriding everything else. After quickly assessing the wound and instructing others to take him to the healing chambers, she turned back to us, her focus returning entirely to the stones.

"Come," she urged, her voice tight with controlled excitement. "Quickly. To the Harmony Circle. We must know what these pure stones can reveal, what hope they offer against the growing discord."

We followed her through the settlement. The whispers that trailed us this time were different -- hushed tones of awe, reverence, hope.

"They found the heart chamber." "They faced the Lurkers." "The Sound-Seer carries the pure harmony." The stories were already taking shape.

Iros brushed against me as we walked, a subtle graze of shoulders. Just contact. Just confirmation. And yet it lit something inside me—quiet but unshakable.

Mateha led us directly to her dwelling, the small, clean cave dominated by the simple stone altar holding the Harmony Circle device. The air within felt charged, expectant, waiting.

"Place the retrieved crystals within the circle," Mateha instructed, her voice hushed, reverent. "Their combined songwill be stronger, clearer than any we have heard in generations. Perhaps strong enough now to pierce the dissonance."

My hands trembled slightly as I carefully unwrapped the largest crystal, the clear one veined with silver-blue light that had resonated so strongly with my markings in the heart chamber.

Its surface was cool, smooth, pulsing with a gentle, rhythmic energy that felt like a quiet promise. Following Mateha's guidance, I placed it in the central holder.

Iros, Nirako, and I then carefully placed the other five stones in the surrounding holders, matching shapes and resonance patterns as Mateha directed.

As the final stone clicked into place, the effect was instantaneous and profound. The crystals flared with brilliant white light, far brighter than Kozlan's single shard had produced.

A low, resonant hum built steadily, deeper and purer than I had ever felt, a complex chord of perfect harmony that vibrated through the floor, through the air, sinking into my very bones, aligning something deep within me.

My markings responded instantly, blazing with silver-white light, not painfully this time, but with a feeling of pure, exhilarating connection, like plugging into a perfectly tuned power source.

The residual tension from the Depths, the constant background ache -- it vanished, replaced by a profound sense of clarity and focused peace. The ambient energy of the Aerie, the mountain, even Iros standing close behind me -- it all resolved into distinct, understandable patterns.

"The Harmony Circle sings with true power now," Mateha whispered, awe and reverence in her voice. Tears glistened in her ancient eyes. She looked at me, hope burning fiercely.

"Place your hands here, Sound-Seer. Let this amplified harmony guide your markings. Feel the mountain's true song... and reach out. Perceive the dissonance now. Understand its source. Find its weakness."

Taking a deep, steadying breath, drawing strength from the pure resonance filling the chamber and the unwavering support I felt from Iros, I placed my palms flat in the smooth stone depressions of the Harmony Circle.

The connection surged through me, stronger, clearer, more focused than any previous interface. Shielded and amplified by the pure harmony stones, my perception expanded exponentially.

The visualization exploded behind my eyes, sharp, detailed, breathtakingly clear. A three-dimensional map of energy and sound unfolded.

I saw the Aerie, a beacon of stable blue-green harmony. I saw the Shardwing roosts, their individual signatures still showing faint traces of the jagged red interference, but the underlying pure tones were strong, fighting back.

And then, extending my perception westward, I saw the source. The Echoing Caves. The vast, artificial complex. The failing core. The fractured crystal matrix pulsing with chaotic, uncontrolled power.

And theintent-- the structured dissonance designed to overwhelm, to dominate. Weaponized resonance.

"It's... a weapon," I breathed, the certainty absolute now, chilling me despite the warmth of the Harmony Circle. "Or part of one. The energy broadcast... it's deliberately disruptive."

Echoes flooded my mind, clearer this time, carried on the resonance -- fleeting images of conflict, of Nyxari turning this power against each other, of catastrophic failure during the Great Division.

"I can see the core," I described aloud, my voice steady despite the awe and terror the image inspired. "A fractured crystal matrix in the central chamber. It pulses irregularly, broadcasting the dissonance."

I focused deeper, tracing the energy flows now visible through the interference thanks to the stones' power. "Secondary systems -- defenses -- damaged but potentially active. And a primary power conduit feeding the core... wildly unstable. Fluctuating. That must be the cause of the 'Quieting' cycles Kozlan mentioned."
