The crew discovers the official survey grade is false and Ione forces a safer line through visible labor.
Morning showed the lie in daylight. The official grade marks, painted red on survey poles, promised a gentle rise toward dry ground. Tamsin's level said the rail would dive into peat, drown the first engine, and take half the camp with it. Ione stood knee-deep in mud while workers watched her face for the court habit of blaming instruments. She checked the bubble herself, then checked the string line against Brindle's stone markers. The numbers disagreed with the palace. The mud agreed with the numbers.
"If we pull yesterday's sleepers, we lose the only work that looks like progress," said Harl, the oldest spike hand. His beard dripped rainwater onto the false map. "If we keep them, progress kills us," Ione said. That answer did not feed anyone. It did not put dry socks on swollen feet. She knew the silence after it was not disloyalty. It was arithmetic. Tamsin folded her arms. "You can order it." "I can pay for it first."
Ione took the courier's unused wagon tarp and spread it on the ground as a counting cloth. Two emerald chips remained from the broken cuff, one pearl clasp, and the gold hinge from her traveling mirror. "Hazard wage for pulling false sleepers. Double ration for crews working in standing water. Brindle's people get nail credit for every buried stone they raise." Harl stared at the cloth. "You are selling your mirror?" "Apparently I look better with a route." Someone snorted. The mutiny lost its first tooth.
The work was ugly. Men levered up sleepers that sucked at the mud like mouths. Ogres drove stone cribs under the new bed while children from the reeds sang toll counts to keep the spacing. Ione carried tally flags herself because the camp had no spare clerk and because nobody could call a princess distant while she fell twice in front of the ballast pile. Minister Orlan's courier tried to leave with the old map. Tamsin caught his reins. "Field document," she said. "It stays where the field can insult it."
By noon the corrected line ran three rods north, higher, harder, and much more expensive. The level bubble finally settled between its marks. Harl struck the first new spike and did not look at Ione when he said, "That will hold." From a rail hand, it sounded like a medal. Brindle placed one old survey peg beside the new line. Its hidden notch matched Orlan's private office mark. The minister had known the marsh would sink.
The changed grade also changed the camp kitchen. Water no longer pooled where the cook tent stood, and the crew noticed before they noticed the line. A woman with ballast dust in her hair set down a pot of beans and said, "If the floor stops drowning my fire, I can feed night shift." Ione added cook tent drainage to the route board. Tamsin gave her a sidelong look. "That is not track." "Hungry hands lay crooked track."
Ione drove the first corrected survey flag herself. The mud swallowed her boot to the ankle and made a rude sound when she pulled free. Harl laughed before he remembered princesses punished laughter. Ione handed him the next flag. "If the line is going to mock me, it can mock us accurately." The laugh became work.
The victory lasted until the new grade pointed into the black trees beyond Ashfen. No bird crossed that ridge. Iron scraps near the roots trembled without wind. Tamsin wiped mud from the route map and swore softly. "Blackroot Cut." The crew stopped cheering. Brindle's chain clicked once. "Royal men went around and starved three villages. Railway cannot." Ione looked at the dark ridge, then at the line of workers waiting to learn whether she would finally choose the easy lie. "Then tomorrow," she said, "we ask the trees what maintenance they have been owed."
