IN THE TEETH OF THE LEVIATHAN RANGE

The letter arrived on a day that tasted of iron and ending. Kaelen, once a celebrated peak-scribe of the Celestial Spires, now mended fishing nets in the salt-rot port of Marrow's End. The parchment was thick, creamy, and utterly out of place among the fish scales and frayed hemp.

It bore a single line, stamped with a wax seal depicting a mountain being sundered by a spear.

"The Range hungers for those who can listen. Your debt to the Guild is recalled. Assemble at the Sky-Bitten Lodge in three days. Refusal is default."

Kaelen's hand, scarred from an old ice-fall, did not tremble. The debt. The one he'd taken to save his sister's life, the one that had bound him to the Guild of Measurers in the first place. He'd thought his disgrace-his failure to accurately chart the shifting Serpent's Spine, which had cost two climbers their lives-had voided it. He was wrong. The Guild never forgot.

The Sky-Bitten Lodge was a fortress of weathered timber and stubbornness, perched on the last true foothill before the world went vertical. Inside, the air was thick with the smell of boiled leather, cold stone, and ambition. The party he was to join was already there.

There was Renn, the Guild's appointed Pathfinder, a woman of few words and eyes the color of glacial silt. She moved with the lethal grace of someone for whom climbing was a form of thought. Borin, the Gear-Granny, was a squat, irritable genius whose pack seemed to contain a small forge and an entire mechanics' workshop. He was already arguing with the fourth member, Jaspar.

Jaspar was not Guild. He was Iron Dynasty, an emissary from the lowland empire that viewed mountains as obstacles to dominion. He wore opulence like armor fur-trimmed coat over articulated steel, a weather-glass that glowed with internal light. He was funding this expedition, and he made it plain.

"The Leviathan Range is the last blank space on our maps," Jaspar said, his voice smooth as oiled stone. "My masters wish a route, a pass through its teeth for the Silk-and-Steel Road. You will find it."

Renn merely glanced at the map unfurled on the table. It showed the Leviathan Range not as peaks, but as a jagged jawbone biting the sky. The interior was blank, labeled only: "Here Be Pulse."

"We're not paving a road," Renn stated flatly. "We're assessing viability. For the Guild. The Range decides what's possible."

Jaspar's smile was thin. "And I decide what's profitable."

Kaelen's role was clear and cruel. He was the Scribe, the Cartographer. His job was to listen. The Guild's doctrine held that the oldest, wildest mountains were not inert stone; they had rhythms, whispers of seismic breath, telluric currents they called the "Pulse." A good scribe could hear it through special resonating stones and calibrated needles, mapping not just rock, but the mountain's mood. It was this skill, now rusted with disuse and guilt, that the Guild had bought with his debt.

Borin shoved a pack into his arms. "Your gear. Don't lose the listening-stones. I don't carve 'em for fun."

The pack was heavier than it looked. It felt like his past, strapped to his back once more.
