The tower was visible. There was no way across.
Sera stopped before Najeon’s old bridge. Wind passed through its two missing boards. The custodian’s stop board remained on this side. Bringing timber today did not justify removing it first. The orchard detour still reached the permitted ground-floor observation room. They were seeking another eye height here, in place of the forbidden upper floor, without declaring that existing path gone.
Seventh morning after the closure notice. Sera, Liv, and Tio had taken the gentler village road with the western village custodian. Her knee required two rests. An adult carpenter and carrier from the village brought heavy materials by handcart. Tio’s sore finger still belonged nowhere near a hammer.
Nume stayed at Roan to check boat maintenance. A captain could not follow all day to inspect one new support. They had left drawings of rocks and coastal obstructions actually seen on earlier voyages. Those were questions for today’s ground, without supplying a substitute boat trial.
Both reserves remained boxed at Roan. Edin and Varen maintained the ordinary beacon and prepared comparison times. Today’s aim was another patch of ground for two people in different positions, without lighting a stone to gain a lane.
Tio eyed the timber. “Not enough for a bridge.”
“We didn’t come to check that.”
He looked relieved. A few dry planks invited demands to join a broken way. This ravine lacked bearing places as much as board length.
Liv indicated the low wall. Behind it lay a broad ledge where someone might sit without stepping beyond the cliff. Yesterday’s dry rectangle now contained roots and cracked stone.
Before approaching, Sera asked who had recently walked there and which way rainwater ran. The custodian had patrolled inside the wall, without checking the lower outer surface. They would begin inside.
The carpenter pressed ground with a long stick and removed loose surface stones. Sera did not record that as a complete test of human weight. Leaving the edge clear, the adults gradually narrowed their search from dry ground within.
The first candidate offered a clear view. No trees obscured the outer rock. Delighted, Sera raised her ruler, then saw a fine ground crack leading toward water.
The carpenter shook his head. Extra beams would fall with the soil if it slipped. She marked the first rectangle stopped. Giving up the clearest place made the remaining drawing look suddenly small.
Liv suggested one step farther behind the wall, though it hid the target rock’s lower part. Sera admitted she had thought observation points must see more.
“A place to see more, or a place to stand longer. Today we may need the second.”
Neither choice guaranteed a usable point. Another actual position must share its target. Sera selected a white scar near the rock’s top.
Tio said it vanished when seated. From a low box, the wall cut his eye line. Had Liv said it, Sera might have understood immediately. From a young carpenter she first wanted to answer: raise the support.
She swallowed that reply and sat herself. At bent-knee height, half the sea vanished. White bird droppings showed on a smaller rock leftward. A mark that might wash away in days could not be a permanent target.
The custodian identified an old quarry face, a square cut high on rock. Sera examined it in cloud shadow and sun. Both allowed identification, though higher tide might hide its lower line.
They narrowed the observation. Not the whole rock: its upper cut together with the large peak behind. Confusion in fog or changing tide meant stop. Today supplied one tidal condition, without proving every other.
For support height, Tio first drew out a broad board. The adult carpenter waved it away. An observing stand needed no large platform merely because of its name. More area caught more wind and left less room to inspect underneath.
Tio fell quiet. Sera recognized the face of someone hearing their first chart challenged. She did not explain for him, but waited while the carpenter demonstrated the structure with empty hands.
This low platform would not project people toward water. It provided comfortable footing on dry ground and consistent height for ruler and reflector. If using it required clinging to an outer rail, they would abandon the candidate.
Tio shortened his drawing’s long line. Behind the reduced support remained room for one retreating step. Sera entered that space as a dimension. A place to flee sounded frightening; room to turn made it part of the design.
The first assembly finished before lunch. Adults drove nails and moved heavy boards. Tio read dimensions and chose component directions. Sparing his hand did not leave him without work, though sometimes it emerged from his pocket as if wanting the hammer.
Sera did not order rest each time. She waited for him to put down the nail tin and choose the drawing. Twice he reached out; the third time his hand stayed pocketed. Such choices needed practice too.
The unloaded support lifted on one side. A small stone beneath had tilted. Rather than adding nails, the carpenter raised the board and inspected its base. Sera learned again that seeing distant water accurately began with looking close beneath.
They ate inside the wall. The carrier had another load that afternoon and asked when to leave. Investigation materials had not arrived free. The custodian counted permitted maintenance stock separately from today’s components and sent the remainder back.
Sera did not imagine a larger platform. Extra timber created no extra hours. After the little place was finished, the adults must return to their next work.
Liv split barley bread. Sera described Nerin’s seedlings: because the captain watched the lane, their owner could watch soil.
“Who’s watching the ground today?”
The carpenter kept turning toward the repaired support as he chewed. While they trusted timber, he could not leave it alone. After eating, Sera took the duty of guarding the unloaded frame. Once, the carpenter had time to look at the sea.
In the afternoon they agreed an order for seated testing on dry ground. The carpenter inspected support and boards first; then the custodian sat. Nobody jumped at the edge or loaded several people together. Sera watched for movement beneath before reading distant targets.
Her turn followed. Bending her knee slowly, she found stable footing. No reflector was fixed yet, but the repeated eye height was perceptible. She accepted the ruler with delight.
Liv found the same target from another dry place apart from the wall. Two different positions, without adding a mirror to multiply one pair of eyes. Sera recorded each location, eye height, and tidal time.
Two people identifying one rock here did not make a safe connection to Roan. No boat marker was present; no stone was lit. They had confirmed target identification from two land candidates only. She did not title it a new lane.
A gust shook the custodian’s hand-held reflector. Tio wanted a higher windbreak beside the support. If it caught the whole wind, the carpenter said, it might drag the frame along.
Sera hesitated, then stopped. It must remain a candidate for gentler wind. Finding a good place did not oblige them to force it through bad conditions. Before a large windbreak, Tio made a stop sign.
Before leaving, the carpenter demonstrated the fastenings directly to the custodian. This was no viewing platform for anyone to mount after they departed. Rope and signs restricted approach; loose joints and ground needed checking before next use.
Sera added a drawing showing, even without reading, that people must not stand outside. Tio drew a large person and small reflector. The figure kept leaning, making them laugh. Finally they drew the place farther inside, where someone could stand straight.
Could it be used after the next rain? The carpenter had tested dry ground today. After rain, pooled water and soil below required rechecking. Sera did not bury that explanation in small print. Immediately under the first line she wrote check before use.
Tio put his name at the drawing’s edge. Was that allowed when he had driven no nails? He had selected materials and changed the height, the carpenter said; record those tasks. Beside his name, Tio entered chosen boards and revised dimensions. Like names behind yesterday’s map, this platform retained who had done what.
They looked across the bridge before leaving. Najeon’s upper floor remained forbidden. Its poorly recovering stone still lay in its chest. A new platform had repaired neither. It provided another choice for limited observations while the tower could not be used.
Sera delighted in that choice’s size. A day’s work had not changed the archipelago, but tomorrow someone could stand on actual ground. Smaller than a great promise, the achievement could be carried home.
They reached Roan before daylight ended. Resting his leg, Varen received their drawings. Edin checked approach conditions and stopping criteria. Thirteen days remained. Neither reserve had been lit. For the next test, they would consider one limited stone use and land comparison, without sending a boat.
Liv placed her timekeeper on the table. Sera set Roan’s hourglass beside it, preparing to check the requirement of one target at one time. They had not yet compared them today.
Tio drew two empty observation fields beneath the platform sketch. Sera almost entered tomorrow’s target, then raised her pencil. Two positions existed, but nobody had seen whether those eyes opened at the same moment.
Liv opened the hourglass cover.
“If tomorrow’s values differ, which will you call wrong first?”
Sera left both fields empty. They had ground on which to turn. She would have to be ready to leave the times of failed observations on the page as well.
