With the route settled, Paxa Sel pulled her small calfskin ration ledger from her apron pocket and laid it beside her wooden tea bowl.
The healer dipped a steel pen into a small travel inkpot and ruled three clean upright columns across the unlined paper. Out on the frontier, romantic notions of courage and fellowship always collided with the brutal arithmetic of heat intake and water transport.
“An expedition isn’t an army,” Paxa said, her pen scratching against the page with dry, rhythmic care. “The common mistake made by lowland merchants is hiring twelve strong lads from a tavern, buying six heavy baggage wagons, and setting out with flags flying. Within five days, twelve men and six draft horses eat three hundred pounds of grain and drink four hundred gallons of water. By the second week, half the party is doing nothing except hauling provisions to feed the other half. When a gully washes out, the wagons get stuck, the draft beasts founder in the mud. The expedition collapses before it crosses the county line.”
She looked around the kitchen table, her sharp gaze resting on each face in turn.
“We travel light, we travel fast, and we keep the party small,” Paxa continued. “Four people. No more. Four mouths can live on two pack frames and my grey mule. Four people can sleep under a single oiled canvas tarp, share a single fire without drawing the attention of ridge bandits, and move through rough scree without leaving a road wide as a cattle drive.”
She listed the four names in her ledger:
1. Kezra Venn: Step Mapmaker. Team navigator, strata sounder, and spatial anchor. 2. Yseld Arken: Professional Route Finder. Scout, high-ground pathfinder, and defensive outer edge guard. 3. Paxa Sel: Field Healer. Medical clerk, water ration master, and mule driver. 4. Fellis Dain: Survey Rigger. Knot specialist, clockwork advantage hoists, and anchor stone cutter.
“I’ll join the march as far as the Saltglass caravan junction,” Paxa said. She looked at Maud. “I have a standing seasonal contract with the apothecary guilds down in the bitter salt basin to inspect their stone shipments and certify sulfur purity. If we travel together through Blackglass, your daughter has medical oversight while her nervous system adapts to the class recoil. My mule carries the heavy water casks and replacement copper wire. In Saltglass, we reassess.”
Paxa opened her medical kit and set out its contents on the bench to show the packing discipline.
“Medical supplies take priority over personal luxuries,” Paxa said, pointing to each item. “Six rolls of boiled linen bandages, sealed in beeswax cloth against moisture. Three bottles of willow-bark spirit-extract for high fevers and systemic inflammation. Two jars of pine-tar and sulfur salve to dress pack galls on the mule and blistered heels on humans. A flask of packed salt water to maintain electrolyte balance. Four sets of ashwood finger and limb splints. And my brass pitch pipes to monitor Kezra’s sound nerve function after every transit.”
She turned back to her ledger, dipping her pen once more.
“Now for the ration arithmetic,” Paxa continued. “In the fiery scree of Blackglass, four adults walking twelve miles a day need one and a half pounds of dry rations each per day: very thirsty barley meal, dried field peas, smoked bacon, hard cheese, and dried sour plums to prevent scurvy. That’s six pounds of food a day, forty-two pounds for a seven-day crossing. We can carry that on two wooden pack frames without straining human backs. Heavy grain and cured meats sit at the bottom of the frames, tight against the spine to keep the balance point low. Emergency tinder, spare socks, and medical bandages stay at the top in greasecloth sacks.”
“And cooking fires?” Fellis asked from his stool. “Do we light fires on the plateau?”
“Only in sheltered ravines after dark,” Yseld replied, her raspy voice cutting in. “Dry birch peat and willow charcoal only—no damp pine that throws white smoke into the sky. On the Blackglass ridge, smoke can be seen from ten leagues away. The ridge herders who collect illegal tolls watch the horizon like hawks. In dry camps, we eat cold very thirsty barley mixed with oil and a pinch of salt. It tastes like gravel, but it keeps legs moving.”
“And water?” Yseld asked, turning back to Paxa. “Blackglass has three known seepages, but the second one dries up after the eighth month. In Saltglass, surface water is poison.”
“Water is the hard limit,” Paxa agreed, her face darkening. “In dry country, an adult carrying a thirty-pound load must drink three quarts of water every twenty-four hours to maintain kidney function and prevent delirium. Four people need three gallons a day. My mule can carry two ten-gallon oak kegs in her wicker side panniers without breaking her stride. That’s twenty gallons, nearly a seven-day supply if we supplement with boiled slow leak water whenever Yseld finds a seep. But if the mule goes lame. Or an oak bung leaks, we’re thirty miles from a well with three cups of water per person. That’s the reality of the road.”
Paxa closed her inkpot with a sharp click. “Every extra person you add beyond four breaks the water equation. Add a fifth person, and you need a second mule. A second mule needs forty pounds of oats or dry fodder because there’s no grass on the bitter salt flats. Carrying that fodder adds another sixty pounds of pack weight, which slows your pace by two miles a day. Slower pace means more days in the dry zone, which needs more water kegs. That’s the logarithmic trap of desert travel: giant expeditions die of thirst trying to carry enough water to feed the beasts carrying the water.”
Across the table, Maud Venn had listened to the arithmetic in total silence. Her hands rested flat on the scrubbed pine boards, her broad shoulders tense beneath her woolen shawl. Paxa’s pen stopped scratching. Then, the master potter lifted her head, her gaze bypassing Kezra, Yseld, and Paxa to fix directly on the young man sitting by the hearth.
“No,” Maud said.
The word fell into the warm kitchen like an iron pig dropped on a hearthstone.
Fellis Dain blinked, his mug of watered cider pausing halfway to his lips. “Mistress Venn?”
“Not you, Fellis,” Maud said, her voice trembling with a ferocious, protective anger. “Kezra is my daughter. She has this strange, frightening class in her bones. She has her brother’s letter burning in her pocket. If she must walk into the mountains to search for Davren, I can’t lock her in the loft. Even so, God knows my heart breaks to see her go. But you’re nineteen years old, Fellis Dain. When your mother died of the winter cough twelve years ago, I washed her shroud with my own hands. I brought barley porridge to your father’s house every night for three months. Your father broke his back in the clay pit to teach you the rope trade and leave you an honest living. You have a good shop in this village. You have the parish contract for derrick lines and kiln cables. You’re not a Venn. You have no business dying of thirst in a bitter salt desert for our family’s sorrow.”
Paxa Sel reached across the table, laying her hand over Maud’s trembling fingers. “Mistress Venn,” the healer said. Her voice dropped into a quiet, solemn rhythm that held the kitchen still. “I have buried companions in the lowlands who marched with pride and forgot water. I’ve seen what happens when an expedition carries too much freight and too little discipline. I don’t take nineteen-year-old riggers onto bitter salt flats for sport. I take Master Dain because without an anchor craftsman who can test bedrock with a hammer, your daughter will slip from an unseated pin before she reaches the second ridge. We’re not gambling with his life. We’re taking the exact field skill needed to keep four people breathing.”
Maud looked from Paxa to Fellis, her breathing slowing as she took in the healer’s steady, unbending eyes. “And the bitter salt water?” Maud asked, her voice cracking slightly. “They say the salt water in Saltglass burns the throat like lye.”
“We carry three pounds of ground alum crystals and two bags of crushed willow charcoal,” Paxa explained. She pointed to her pack pannier. “When we draw water from a saline slow leak, we stir in half a spoonful of alum. The alum flocculates the suspended mud and heavy stone salts. He dropped them to the bottom of the pot in ten minutes. Then we decant the clear surface water through charcoal cloth. It removes the bitter soda taste and leaves the water safe for human kidneys. I have run this filter on three border circuits. No patient under my watch has ever suffered kidney failure from desert water.”
Maud looked at the worn leather panniers resting against the wall. “Then take two jars of sheep fat from my dry-chest,” the master potter said. He wiped her eyes on her apron hem. “The bitter salt dust eats through dry leather in four days. If you don’t grease your boot welts and the mule’s harness every evening before sunset, the salt will rot the stitches until your packs fall into the scree.”
