IN THE TEETH OF THE LEVIATHAN RANGE

They found the valley on the seventeenth day. It shouldn't have existed-a vast, sheltered basin hidden between the tallest fangs of the Range. And it was alive.

A forest of stone trees, sculpted by millennia of wind into uncanny organic shapes, covered the floor. A river of milky-blue glacial meltwater flowed silently. And the air hummed. The secondary rhythm Kaelen had heard was now a palpable thrum, emanating from a vast, arched entrance in the valley's far wall.

"The Source of the Pulse," Kaelen whispered, his scribe-plate alive with swirling, beautiful patterns.

"A geode chamber of unheard-of size," Borin breathed, his technical zeal overriding his caution. "The resonant energy... it could power a city!"

Jaspar's eyes glinted with pure, avaricious fire. "Not a city. An empire. This isn't a route through the mountains. This is the prize. A battery of limitless power."

Renn placed a hand on her ice-axe. "Our mandate is survey, not extraction."

"Your mandate," Jaspar hissed, "is funded by my treasury. And I say we claim it." He signaled to the two hulking, silent guards he'd brought. They hefted packs laden not with climbing gear, but with demolition charges.

A furious argument erupted. Kaelen stood at the precipice, staring into the archway. The Song from within was mournful and majestic. It wasn't just energy. It was aware. He felt it in his core, a gentle, ancient attention focusing on them-the irritants in its skin.

"Stop," he said, but his voice was lost in the shouting.

Jaspar's men rushed the archway. Renn moved to intercept, a blur of motion. Borin yelled about unstable resonance.

Kaelen did the only thing he could think of. He slammed his listening-stone down onto his scribe-plate with all his strength.

CRACK-SSSSSSSHOOOOOM.

The sound was not loud, but profoundly wrong-a shattering of sacred harmony. The clear quartz exploded. The shockwave of dissonance rippled out, visible as a warp in the air.

The mountain responded.

The ground didn't quake; it recoiled. The arched entrance seemed to clench like a muscle. Stone teeth ground together above it, sealing it shut with a final, deafening boom, crushing Jaspar's guards within. The stone forest trembled, and the river changed course, its water turning a furious, opaque white.
