“If an invention works only when no one needs it, you have built a demonstration, not a solution.”
— A workshop maxim attributed to travelling artificers
The trouble with a brilliant idea was that it rarely survived contact with the ground. Khepri’s newest invention had made that contact three times before breakfast. On the fourth attempt, its wooden frame collapsed beneath six sacks of grain. A weight rolled out of the wreckage and struck his foot.
“Ow!”
“That,” Ibara said, “is what happens when you ask two thin pins to carry six sacks.”
Khepri balanced on one foot. “I was testing the pins.”
“And you’ve discovered?”
“The joint turns the load onto the pins. I need wider ones.”
“Six sacks. Two thin pins. Count the load before you build.”
Ibara’s workshop occupied two wagons at the edge of the Elune caravan. One held tools, benches and small drawers filled with precisely labelled components. The other housed finished commissions: prosthetic supports, surgical frames, a mechanical loom and several inventions Khepri had been instructed not to examine without supervision.
He liked everything about the workshop except that last rule.
Ibara stooped over the shattered frame, her broad shoulders filling the space beside the bench. Greying coils were cropped close above her square, bronze-brown face, and a faint scar crossed one eyebrow. Her strong, work-worn hands moved among the broken pieces with practised care.
“Remind me what it’s meant to do.”
“Carry patients. Lighter than our present stretchers, stronger, easier to store. It folds.”
“It folded under six sacks. That’s not the folding you want.”
“I meant it to fold at the hinges, not under the patient.”
She lifted a broken joint between two fingers.
“Show me the drawings.”
Khepri retrieved a stack of pages from his satchel. He had begun them after watching Meka’s bearers struggle to move him without unnecessary jolting. He remembered how carefully they had timed each step, and how every uneven patch of ground had demanded another adjustment. The work had followed him through supper and into the night, even after Simi threatened to hide his charcoal.
Ibara spread the drawings across the bench and wrote three words above them.
*Strength. Weight. Movement.*
“Those are your problems,” she said.
“Why does the hinge take so much of the weight?”
“Start with these.”
She pointed to the main support.
“You’ve strengthened the frame here.”
“By making it thicker.”
“And therefore heavier.”
Khepri frowned.
“You’ve made the joint smaller so it folds neatly,” she continued. “What happens when the load shifts?”
“The joint takes more weight.”
“And breaks, as it has just demonstrated.”
He pulled the drawing closer. His design demanded strength and mobility from the same part. The more freely it moved, the less reliably it held the patient. But fixing it in place would leave him with an ordinary stretcher.
Ibara placed two wooden pieces before him, one rigid and one fitted with a small hinge.
“What if the support carrying the weight isn’t also responsible for folding?”
Khepri stared at them.
“Separate the functions.”
“Perhaps.”
He began drawing again. By the time he had moved the folding joints away from the load-bearing rails, the device was stronger on paper. It was also bulkier.
“It won’t fold as small.”
“No.”
“I wanted both.”
“Then you’ll need to work for both.”
His eyes settled on a drawer of refined bronze alloys.
“What about lighter joints?”
“We could use those.”
“How much?”
Ibara named the price. Khepri nearly dropped his charcoal.
“For two joints?”
“Bronze costs money. So does the time it takes me to prepare it. You’ll pay for both.”
He sat back. The alloy would solve one problem but consume resources better used elsewhere. He could reinforce only the critical joints, use ordinary bronze for smaller connections and let carefully chosen timber carry the main load.
He began calculating. At first, every compromise seemed like a defeat. Then the drawing acquired a different kind of elegance: each part with a distinct purpose, no unnecessary weight, nothing pretending to do three jobs when one would suffice.
Ibara inspected his revised design.
“The rails carry the weight now.”
“Will it hold six sacks?”
“I haven’t tested it yet.”
“That will do for today. Next, we persuade it to work outside your head.”
Khepri nudged the broken pin with his boot and opened his drawings again.

Simi arrived at Meka’s recovery shelter carrying two wooden boards and a handful of coloured discs.
The boy was awake, propped against pillows. His mother sat beside him, peeling an orange. The immediate danger from his head injury had been treated, but he still struggled with some movements, especially in his left arm. The physicians were watching his recovery carefully.
Meka eyed the boards.
“What are those?”
“A game.”
“Finally.”
His mother chuckled. “He’s decided the ceiling has become boring.” She adjusted his blanket where it lay near his left hand; Meka pretended not to notice.
“There are twenty-three beams,” Meka announced.
“Twenty-four,” Simi said.
He counted again, then gave her an accusing look. She placed the simpler board on the table. Coloured discs could be moved along shallow grooves into matching hollows. A second board had narrower paths.
Meka immediately reached for the harder one.
“That looks better.”
“We’ll start here,” said Physician Tàlé, joining them.
“I’m twelve.”
“Then let’s start with what you can manage. Your right hand first, please.”
Meka accepted the challenge.
Using his right hand, he moved a blue disc to its place without difficulty. Then Simi asked him to try with his left.
His fingers closed awkwardly. He lifted the disc, but it slipped as he tried to follow the groove. He picked it up a second time; his hand drifted sideways, and the disc fell onto the table.
He pushed the board away.
“Stupid game.”
His mother lifted a hand.
“I can do it,” he snapped, then looked ashamed of his tone.
Simi kept her voice steady.
“I believe you. But we don’t have to finish it this way.”
He studied her suspiciously.
“What way?”
“What do you usually do when you’re not climbing orchard walls?”
“Fishing. Running. Making kites.”
“Kites?”
“My cousin and I make them. Mine are better.”
“According to you?”
“Obviously.”
Simi picked up a soft length of cord.
“Do you tie the strings yourself?”
Meka nodded.
“Then perhaps the kind of movement you’re practising will help you do that again.”
Tàlé drew the board closer.
“Kite strings need careful fingers. We’ll practise for a little while today.”
He helped the boy position his arm comfortably and adjust how he approached the task. Simi held the board while Meka tried again, this time with assistance and a smaller movement to complete.
The disc slipped. He tried once more. It travelled a little farther. By the end of the short session, he had placed two discs into their hollows. His left hand was trembling, and he looked exhausted.
“One more,” he demanded.
“Tomorrow,” Tàlé replied.
“I can do another.”
“I know you’d like to. Let your hand rest now.”
Meka sighed. Simi recognised the expression. It was the same one Khepri wore whenever someone took away his tools.
“Will I make kites again?” Meka asked.
Tàlé considered the question.
“Let’s practise the movements you use for tying a kite. We’ll see what gets easier.”
Meka tapped the edge of the harder board.
“Then bring that one tomorrow.”
“We’ll ask Tàlé what you’re ready for,” Simi told him.
“Everybody says that.”
Meka looked away, and his mother rested a hand on his shoulder.
Later, when he was resting, Simi helped the physician update the recovery notes.
Tàlé wrote down what Meka had managed: two discs placed, one dropped, ten minutes before his fingers began to shake. He asked Simi to leave room on the page for the tasks the boy wanted to try next.
“I thought the operation would be the hardest part,” Simi admitted.
“It was the most urgent part,” he said. “That isn’t always the same thing.”
At Meka’s bed, his mother had tucked the abandoned game beneath the table, where he could see it on waking.
“His life was saved,” Simi said. “But he still has so much to do.”
“He’s been asking about kite string since he woke,” Tàlé said.
She remembered the tale of Nàrúmi, whose knowledge had travelled through the work of a thousand healers. In the recovery shelter, that story seemed less distant than it had beside the cooking fire.
Tàlé opened a set of transport records.
“Would you help me with these?”
Simi drew her stool closer. The pages recorded how patients were moved between shelters and wagons. Some could walk with assistance. Others required careful support. The more serious a person’s condition, the more thought went into each movement.
“How do you choose a carrier?” she asked.
“By considering the patient, the people carrying them and the place they need to travel.”
“My brother’s building one.”
Tàlé looked up.
“Ah.”
“He’s taking it seriously. Ibara makes him measure everything.”
“Is Ibara supervising him?”
“Yes.”
“Then someone will check the measurements before he uses it.”
Simi told him what she knew of Khepri’s design: a light frame, folding supports, a way to keep the patient steady over uneven ground.
“Promising,” he said. “But who loads the patient onto it?”
“The bearers?”
“How? Can they reach from both sides? Will the rails obstruct them? How wide is the frame? How long does it take to set up when somebody urgently needs moving?”
Simi stopped writing.
Simi drew a space for the bearers’ hands beside the frame. Her brother had measured the machinery; now she had to make sure people could use it.
“If it takes four people just to load a patient,” he said, “how will two bearers manage on the road?”
She drew a rectangle on a spare sheet and began changing its edges.
“Would a removable side help?”
“It might. Provided it couldn’t open by accident.”
Simi added handles, access spaces, restraints and door widths to the drawing. Each addition called for another measurement, and she kept working.
* * *
Before leaving, Simi watched attendants help a patient from a bed onto a transport carrier. They stopped to adjust their handholds, then had to manoeuvre carefully through a narrow doorway. The machine had performed its task, but only because experienced people had adapted to it. Khepri’s diagrams assumed an orderly load centred perfectly in the frame; living people, she realised, rarely arrived in the perfect position. She made a note about access from either side, and another about allowing room for the bearers’ hands. When Meka’s mother asked what she was drawing, Simi explained her brother’s project. The woman told her how unsettling it had been to see the bearers struggle to move her son comfortably. Simi added a final instruction to the page: make it gentle as well as strong. She smiled, imagining Khepri’s outrage at the growing list of requirements.
* * *
At the end of the day, Ibara found Khepri still bent over his fourth design. He had made the principal supports sturdier and moved the folding joints away from the load. He had spent several hours calculating the materials and then another hour complaining about their cost.
“Does it meet your requirements?” she asked.
“Most of them.”
“Which doesn’t it meet?”
“I haven’t tested the clearances.”
Ibara studied the drawings.
“Check the door width before you call it finished.”
A porter squeezed past them with a patient, catching his sleeve against the narrow doorframe. Khepri glanced at the carrier drawing in his hands. Its clean, generous measurements suddenly looked ridiculous.
He crossed out a joint, moved the locking rail and began again, this time allowing enough room for the doorway.
At supper he found Simi reading through a page of patient observations. She had drawn a hand beside one note, marking where Meka’s grip still faltered after the operation. When Khepri mentioned his new carrier, she asked where the patient would hold on and whether the frame would allow a physician to reach him without lifting him again. He had no good answer.
Simi did not mock him. That was more unsettling than if she had.
“Can I borrow your observations?” he asked.
“These are patient notes, Khepri. Ask Tàlé what you’re allowed to see.”
“Right.”
“And you can ask me how a patient actually moves.”
He looked down at the drawings, already seeing which supports would make that difficult.
“Tomorrow, then.”
“Tomorrow,” she agreed.
Simi folded the notes and kept them out of his reach until he promised to ask Tàlé first.
