The single animal fat candle on Maud Venn’s kitchen table guttered slightly as a draught slipped beneath the heavy cedar door.
Kezra stood over the printed merchant chart, her right index finger planted firmly on the snow-capped symbols representing the high northern Spine. The flame cast her shadow long and dark against the plaster wall. It trembled as the mountain wind brushed the cedar shingles overhead. Across the room, leaning against the rough corner plaster beside the clock, Davren’s ash walking stick stood in the shadows. Its carved grip dark with the oil of his hands, an unanswered question left behind eighteen months ago.
“Look at where we’re,” Kezra said. Her voice rose with an impatience she could no longer suppress. “Kilnstep sits in the southern foothills of the Spine. Alderfast is thirty leagues due north, tucked between the second and third granite ridges. If we walk north, every mile we march brings us closer to Davren. If we turn east across Blackglass and then southeast into Saltglass, we’re marching directly away from him. It’s forty leagues of desert and fiery rock in the wrong direction! We would be spending a month walking toward the low country while my brother is trapped behind the frost!”
Yseld Arken didn’t blink. She didn’t raise her voice or brush Kezra’s finger from the paper. Instead, she reached into her leather vest, pulled out a sharpened piece of black willow charcoal. Then she set it down on the pine table beside Kezra’s hand.
“Draw it,” Yseld said simply.
Kezra stared at her. “Draw what?”
“Draw the northern road,” Yseld commanded, her raspy voice flat and fully empty of mockery. “Pick up that charcoal and draw the route from Kilnstep to Alderfast. Show me which ravine carries the trail past the timberline. Show me which side of the third ridge has running water after the first autumn freeze. Show me where a pack mule can cross the Black Ravine without breaking its legs on loose scree. And show me what scale of stone blocks the pass into the basin.”
Kezra’s hand hovered over the willow charcoal. The dark wood was light and brittle between her fingers.
She looked down at the white parchment of her open notebook. She looked at the printed merchant chart with its neat little drawings of pine trees and blue rivers. She tried to picture the high ridges where she had carried Eddic down the mountain six days ago. Beyond that first limestone shoulder lay the great granite wall of the Spine—a jagged, white barrier rising six thousand feet into the grey sky. It was flanked by the dark, tangled resin forests of Hushwood.
Her mind searched for a landmark. She remembered Davren talking about the gorge, about the old road wardens’ post that had burned twenty years ago, about three limestone stair treads... But between those three stair treads and the village of Kilnstep lay fifty miles of unmapped upright wilderness.
“The northern approaches aren’t an open road, Venn,” Yseld explained, her voice steady and relentless. “The lower valleys are choked by Hushwood—ancient resin pine forests where the needles fall four feet deep and rot into acidic sponge. There are no pack trails through Hushwood. The timber is so dense that a mule can’t turn its pack frame between the trunks. The deadfall creates natural brush dams that turn every gully into a stale mire. Above the timberline, you reach the Black Ravine. It’s an upright gorge four hundred paces deep, carved by ice-slow meltwater, with walls of rotten shale that shear off under the weight of a goat. Where do you cross the Black Ravine?”
Kezra stared at the blank white margin of her paper, the charcoal motionless in her grip.
“And what about the weather?” Yseld continued, leaning over the table. “In the high Spine, katabatic winds roar off the glaciers at sunset, plunging the heat by forty degrees in twenty minutes. If you’re caught on an open col without a cut-stone shelter, the wind will freeze your eyelids shut before midnight. Three different routes have been tried by lowland climbers. The western chimney, which is choked with ice roof ledges that collapse in the afternoon sun. The central gorge, which ends at a sheer five-hundred-foot waterfall wall. And the eastern cross. There, the black shale slides into the deep pit every autumn. Which of those three death traps do you plan to take your mother’s neighbor through?”
Paxa Sel leaned forward, resting her chin on her hands. “And there’s the physical reality of the human body, Venn. At nine thousand feet, the air holds half the oxygen of this valley. A climber burns four thousand calories a day merely shivering in a wet coat. Without acclimatized lungs, lung fluid swelling sets in within forty-eight hours: fluid fills the air sacs of your lungs, you begin coughing pink foam. You drown in your own secretions on a barren rock shelf. In cold gale conditions, a human mind loses executive judgement. You tie knots with fewer turns, you misread compass bearings. You forget to check anchor pins. Who carries the oxygen draughts? Who carries the splints when someone slips on black ice?”
Kezra’s chest felt tight. She looked down at the willow charcoal in her hand. She felt the brittle carbon crumble slightly under her thumb.
“And then,” Paxa added softly, “there’s the question of your class. What’s your current rank?”
Kezra swallowed. “Step Mapmaker. Four paces square, two paces deep.”
“Can a Step Mapmaker move a mountain slide?” Paxa asked, her cold and exact voice cutting through the room like a razor knife. “Davren’s letter says the gorge gallery collapsed. A mountain collapse in the Spine doesn’t mean four wheelbarrows of gravel that you can shovel aside with a garden spade. It means eighty thousand tons of shattered limestone boulders, each one the size of a hay barn, wedged together under thousands of tons of hanging cliff. If Davren is behind eighty thousand tons of rock, can you move four paces of gravel, wait twenty-four hours for your global lock to expire, move another four paces, and hope he hasn’t starved while you wait? To breach a sealed mountain pass, you need higher ranks. You need Plot scale—sixteen paces square and eight paces deep. You need Reach scale—sixty-four paces square and thirty-two paces deep. And according to the old laws, how does a map maker unlock those ranks?”
“By completing honest circuits across distinct ecologies and walking nonstop routes,” Kezra answered quietly.
“Exactly,” Yseld said, tapping the charcoal against the table. “The class doesn’t advance by wishing, and it doesn’t advance by sitting in a pottery shed. It advances when your boots sound the subsoil of different stone ecologies. Kilnstep gives you limestone marl—your first ecology. The march east across Blackglass gives you fiery dark rock—your second distinct ecology. The march southeast into Saltglass gives you bitter salt plains—your third ecology. That’s three distinct ecologies and sixty miles of nonstop walked route before we even turn back toward the Spine. By the time we find Joric Thane and locate the supply trail that feeds the northern passes, your book will have the circuits and the scale to handle real rock.”
Yseld pointed to the eight-sided brass token lying on the table.
“And more than that,” Yseld said softly, “Joric Thane owns the only supply line that reaches the southern approaches to Alderfast. If Davren cut that die, he was trading with Thane’s outposts. Thane maintains fortified waystations, deep water tanks of fresh water, and blacksmith shops where mules can be re-shod. His outriders know every hidden gully and every seasonal spring between the desert and the mountains. Traveling through Saltglass isn’t wandering into wasteland. It’s following the only established logistics line that penetrates the southern flank of the Spine. You can’t navigate the bitter salt plains by wheel ruts. The wind blows the salt crust smooth every three hours. You navigate by sighting against ancient dark rock fiery plugs and taking bearings on fixed star angles.”
Fellis Dain leaned over the table, his eyes shining with practical excitement. “And on that route, we can carry enough rope and anchor pins to secure every stage. If we go north into uncharted gullies, we carry forty pounds of rope and use it all on the first cliff, with nothing left to haul gear out of the next ravine. But on the caravan route, we can replenish hemp and iron at Thane’s waystations.”
Kezra looked at the chart. The logic was cold, iron-hard, and fully unbeatable. Her desire to run straight north was the impulse of an impatient sister. The detour southeast was the strategy of an expedition that intended to come home alive.
She set the willow charcoal down on the pine table.
Kezra walked to the corner of the kitchen where Davren’s ash walking stick rested against the plaster. She ran her palm over the smooth, dark wood of the grip. She felt the hollow where his fingers had rested. Her brother had always run ahead of her, impatient with measuring ropes and plumb lines, trusting his speed to carry him past danger. But speed had failed him in the high pass. If she was to find him, she couldn’t run. She had to measure every pace of the earth.
“We go southeast,” Kezra repeated, her voice firm and resolute. “Across Blackglass to Saltglass. We find Joric Thane, we trace the brass tokens. We build the circuits that will let’s open the Spine.”
