Chapter 411: A Star Already There

The archive’s reply arrived with copies of the requested sections and a referral.

Master Sera Denhal, Sovereign Dawn. Instruction in the preparation of existing stellar workings. Contact details and workroom hours attached.

Ren arranged an appointment and sent her copies of his observations. Then he used the contact on Halvern’s grey card to ask whether the general could attend. Halvern had overseen his advancement to Six; Ren wanted him there while they discussed preparing for Seven.

Halvern checked the appointment and agreed.

Sera met them in a workroom with a long table beneath a shuttered window. She came forward to shake Ren’s hand, then greeted Halvern. She looked no older than the general, though the coat she wore had been mended at one elbow.

"Put your pages here."

She moved her papers to clear a space. Old black ink stained the turned-back edge of her cuff.

Ren laid out the apparatus sketches, the two single-station sittings and the combined sheet from the matched observations. The original entries followed, with the extract and the archive’s new material beneath them. His other notes remained at home.

Sera drew the first sketch closer.

"Were both boards clear of the tree’s shadow?"

"Throughout the readings. The first is west of the trunk, on open ground. We chose another clear stretch for the second."

"And the ground beneath them?"

"Firm soil with grass. There are flowers near the first station, clear of the stand."

She checked the measured heights and the direction marked on both arrangements. Halvern sat beside the table, where he could read without moving her pages.

"Lyra Moonwhisper surveyed the separation," Ren said. "She took the second station."

Sera turned to Lyra’s entries, then compared them with the combined sheet. She stopped at the unpaired slot.

"A cloud reached her board," Ren explained. "I’d already marked mine. We kept that reading and agreed on another time for both."

"I see the replacement here." Her finger moved to the clock entry. "You compared the slates before and after?"

"Together, at the first station. The offset hadn’t changed within what we could read."

She laid the sheet flat.

"You haven’t resolved a difference with this arrangement. The small separations between your marks fall inside the uncertainty you recorded."

"So we need the stations farther apart?"

"That may help. Better-defined shadow edges may help too. You have enough information here for someone else to judge what you could distinguish. Keep it when you make the next comparison."

Ren looked at the six pairs.

"We couldn’t get a distance from them."

"You haven’t measured the difference you’d need for that. And a smooth track wouldn’t establish stability or integration." She pulled the extract toward her. "For the next part, you asked about heating."

From a cupboard beneath the window, she took two cases. Each held a dull dark plate on a pale, layered mount, a clip-on instrument and a screen on a hinged arm.

"These are a matched pair. One assembly for each station."

She lifted them onto the table and opened the shutter enough to admit a strip of sunlight. With the screens raised, light reached both plates while shields beneath them covered the supports. Ren leaned closer to see how the instruments fitted against their edges.

"Before separating them, run them together through the exposure and recovery described here." She laid a method sheet beside the cases. "Enter both readings. The comparison tells you how closely the instruments agree under those conditions. Repeat the clock check with whoever takes the second station."

"Inside the world, before we start," Ren said.

"And again afterward. Put both checks with that series."

He marked the two places on the method sheet. Their earlier clock comparison belonged to the afternoon they had observed; he would take a fresh one with the receivers.

She lowered the screens over the plates. The instruments continued changing after the light was cut off.

"Record that part too. Use the intervals on the sheet, even if one appears to settle first."

Ren touched the pale, layered edge of one mount.

"The mounts keep the table’s heat out?"

"They reduce it. The supports are shielded as well. Expose the plate as the method shows."

She reached for a notebook with wrinkled page edges and opened it to two drawings of a receiver. The first stood on a flat block. Beside it, readings had been crossed out; the replacement drawing showed layers beneath the plate.

"The stand was heating it from underneath. I kept blaming the plate."

Ren bent over the page. She had retained the first drawing and its readings, with the altered arrangement beside them in different ink.

"You found it when you changed the support?"

"Yes. I had to repeat the series."

She closed the notebook and turned the method sheet toward him.

"Keep the prescribed orientation at both stations. Match the exposure and shaded intervals. Note cloud, accidental shade and any interruption. Take a series across the daylight period at your first station, with simultaneous readings at the other at the agreed times."

"I’ll ask Lyra when she’s available. The measuring cord belongs to her post; she took it back."

"Arrange that before choosing the intervals. You need someone at the other station, and both of you need the same schedule."

Ren read the setup instructions while the receivers cooled. Sera pointed out the separate entries for the instrument comparison and the later station readings.

"Leave your Fire out of the measurement," she said. "Take the response the plate gives you."

He would have to allow for its cooling time when he arranged the intervals with Lyra.

"This measures the response of this plate under recorded conditions," she said. "The soil beside it may behave differently. So may the water, or something growing there. Bring those observations too."

He added a note to his own page, then copied the marks identifying the two assemblies. He tucked the method sheet beneath the lid of the first case.

"I’ll be away for a while," Ren said. "I can take the first readings before I leave. I’d like to return for instruction afterward."

Sera nodded and turned the extract to its fourth group.

"Then we’ll arrange the examination for when you’re back. This part needs someone who can read the stellar working in place. The boards and receivers give us observations to begin with."

"The world’s called Verdance. It already has a sun. I want to learn how to stabilize that working and integrate it properly."

"I’ll come as your guest, with you there. We’ll start at the receiving locations and examine the relationship to the stellar working. We can decide what further observations are needed from what we find."

Ren agreed. Sera moved the papers clear of a larger fitted case at the other end of the table.

Inside it, two grown stones rested a hand apart. A cultivated connection joined them through the bed of the case. Sera laid her fingers beside the first stone and brought the assembly into operation.

Warmth rose above the source. The receiving stone warmed more slowly.

"This is the teaching working. The source, the receiver and the connection are all within reach." She indicated each in turn. "The later exercise is to maintain the transfer while the receiver changes what it can accept. Its response also returns through the connection."

"At Kilnreach I held the release across one joint," Ren said. "Tobin kept the feed and the rest of the branch."

"What you read there will help. Here you’ll also follow what reaches back to the source and how it affects the next part of the transfer. We can change the receiver while keeping the whole assembly in front of us."

She placed her other hand beside the receiver.

"I’m keeping the source steady. Watch what changes at this end."

She altered the receiving working. The warmth from the receiving stone eased, while the source remained steady.

Sera indicated a dressed contact close to the receiver.

"You can read here. Leave the working with me."

The contact was warm beneath his fingers. He followed the arriving Fire through it, then felt a response returning along the connection as the receiver accepted less. The outgoing transfer changed with it. A steady source did not mean an unchanging flow into the receiver.

Farther toward the source, that returning response met a part of the working he could not follow. Sera maintained the transfer while he tried to distinguish its course, but he lost it at the same place.

Ren lifted his hand.

"I can follow the return as far as there." He indicated the nearer stretch. "I lose what it does at the source."

"We’ll work through that part when you return."

She ended the demonstration and let the connection settle before closing the case.

"The teaching assembly stays here. The receivers are the ones you’re borrowing."

Ren looked back at the two dark plates beneath their screens.

"How much can their readings miss?"

"On one preparation I helped oversee, a candidate’s plate readings had settled. A growing terrace in her world kept warming after we’d expected the response to settle there too. We stopped the preparation and examined the terrace before continuing."

"Had the receiver been set up wrongly?"

"No. The plate had settled. The terrace hadn’t." Sera rested her notebook beside the closed teaching case. "We needed to account for both."

Halvern drew Ren’s combined sheet closer and looked at the two station marks.

"Who can report from the places these stations don’t cover?"

"Eira and Vesper can keep records where they’re working. The coastal group can report from the water." Ren considered the distance beyond the landing. "That leaves ground none of them regularly cross. Their reports won’t cover all of Verdance."

"Mark where they come from," Halvern said. "And keep the places you haven’t watched on the plan."

Ren took out his page and noted that beneath the receiver arrangements. He could ask the others to watch conditions they knew: changes in the growing beds, the shallows and the occupied coast. Sera would still have to judge how those observations related to the stellar working.

Halvern waited until he had finished writing.

"I’ll be there for the attempt. We’ll set the stopping limits from Sera’s examination and the preparatory work before you begin."

Ren nodded. The receiving records were something he could start now, while the instruction and examination remained ahead.

Sera brought the empty cases closer to the plates.

"Keep the original station marks. If you want a longer separation, add a station and record how it relates to them. If the ground changes, measure the positions and heights again. Keep the earlier arrangement with its readings."

"Even if I can’t reproduce it?"

"Especially then. Write down what changed. Otherwise we’ll be comparing two different setups without knowing it."

Ren gathered his pages while she checked the loan entry and gave him a copy. They agreed that he would send word on his return to set the teaching session and the visit to Verdance.

He packed the first receiver with its screen folded clear of the instrument. The method and identification records lay beneath the lid, where he could find them before unpacking it.

"Keep the first set," Sera said. "When you come back, we’ll see what changed."

Ren lowered the second receiver into its own case and set it beside the first.
