“Any other options?” Syrinx asked.

“As I see it, we have four in total,” Samuel said. “We can try and get the almanac through a trade exchange. We can use force.” He paused to smile apologetically as his fellow Edenists registered their disapproval. “I’m sorry,” he said. “But we have that ability, therefore it should be examined. Our weaponry is likely to be superior, and our electronic and software capability would definitely be able to extract information from their memory cores.”

“That’s an absolute last resort,” Syrinx said.

“Totally,” Joshua agreed firmly. “This is a culture which wages war over any spare mass on a scale we’ve never seen before. They might not have sophisticated weapons compared to ours, but they’ll have one hell of a lot of them; and Lady Mac is in the front line. What are the other two?”

“If Quantook-LOU proves uncooperative, we simply find a dominion which will help us. We’re not exactly short of choice. The last option is a variant of that: we leave straight away and find a Tyrathca colony.”

“We’ve established a reasonable level of contact with Quantook-LOU and the Anthi-CL dominion,” Sarha said. “I think we should build on that. Don’t forget time is a factor as well, and we came here so we wouldn’t have to deal with the Tyrathca.”

“Very well,” Syrinx said. “We’ll follow Joshua’s tactic for now. Set up a major commercial trade, and tack on the almanac data as a subsidiary deal.”

Joshua kept the same team with him when he returned to the diskcity. This time they were shown directly to Quantook-LOU’s private glass bubble.

“Have you found trade items within your ship, Captain Joshua Calvert?” the Mosdva asked.

“I believe so,” Joshua said. He glanced round the translucent chamber with its barnacles of alien machinery, vaguely disquieted. Something had changed. His neural nanonics ran a comparison check with his visual memory file. “I’m not sure if it’s relevant,” he told his crew through the affinity link, “But several chunks of hardware bolted onto the piping are different now.”

“We see them, Josh,” Liol answered.

“Anybody got any ideas what they could be?”

“I’m not picking up any sensor emissions,” Oski said. “But they’ve got strong magnetic fields, definitely active electronics inside.”

“Beam weapons?”

“I’m not sure. I can’t see anything that equates to a nozzle on any of them, and the magnetic field doesn’t correspond to a power cell. My best guess is that they’ve rebuilt this whole chamber as a magnetic resonance scanner: if they’ve got quantum interface detectors sensitive enough they probably think it will allow them to look inside our armour.”

“Will it?”

“No. Our suit shielding will block that. Nice try though.”

“Did you examine the processor I gave you?” Joshua asked Quantook-LOU.

“It has been tested. Your design is a radical one. We believe we can duplicate it.”

“I can offer more advanced processors than that. As well, we have power storage cells that operate at very high density levels. We offer the formula for superstrength molecular chains; which should be very useful to you, given your shortage of mass.”

“Interesting. And what would you like in return?”

“We saw your ship returning from the sun. Your thermal dissipation technology would be extremely useful to us.”

The negotiation took off well, Joshua and Quantook-LOU reeling out lists of technology and fabrication methods. The trick was in trying to balance them: was optical memory crystal worth more or less than a membrane layer that could guard metal surfaces against vacuum ablation? Did a low-energy carbon filtration process have parity with ultrastrong magnets?

As they talked, Oski kept monitoring the new hardware modules. The magnetic fields they put out were constantly changing, sweeping across the translucent bubble in waves. None of them were able to penetrate their suits. In return, her own sensors could pick up the resonance patterns they generated inside the Mosdva. She slowly built up a three-dimensional image of their internal structure, the triangular plates of bone and mysterious organs. It was an enjoyable irony, she felt. After forty minutes, the magnetic fields were abruptly switched off.

Liol was paying scant attention to the negotiations. He and Beaulieu were occupied reviewing the data coming in from their ELINT satellites. Now they had the observation subroutines customized properly, there was a lot of activity to see on the darkside. Trains moved everywhere, following a simple generalized pattern. Large full tankers made their way inwards from the rim, offloading cargo at the industrial modules, then once they were empty, they turned and went directly back to the rim. Goods trains, those loaded with items produced inside industrial modules, ran in every direction. Liol and Beaulieu were beginning to think they might even be independent trading caravans, forever touring round the dominions. Something Joshua hadn’t asked was if the Mosdva had currency, or if everything was bartered.

“Another vent,” Beaulieu commented. “It’s only seventy kilometres from the captain’s location.”

“Christ, that’s the third this morning.” Liol ordered the closest satellite to focus on the plume. Bobbles of liquid were oscillating amid the gas squirting out towards the nebula. Ebony shapes, radiating brightly in the infrared, thrashed around inside it, their motions grinding down the further away they got from the darkside. “You’d think they’d have better structural integrity after all this time. Everything else they do seems to work pretty well. I know I wouldn’t like to live with that kind of threat looming over me, it’s worse than building a house on the side of a volcano.” His subconscious wouldn’t leave the notion alone; there was something wrong about the frequency of the tube breeches. He ran a quick projection through his neural nanonics. “Uh, guys, if they suffer structural failure at this rate, the whole diskcity will fail inside of seven years. And I’ve included some pretty generous rebuilding allowances in that.”

“Then you must have got it wrong,” Kempster said.

“Either that, or this isn’t a normal event we’re witnessing.”

“Venting again,” Beaulieu called out. “Same web as the last, barely a hundred metres apart.”

In the Oenone ’s bridge, Syrinx gave Ruben an alarmed look. “Access all the visual records from the ELINT satellites,” she said. “See what kind of activity there is in the vent areas prior to the actual event.”

Ruben, Oxley, and Serina nodded in unison. Their minds merged with the bitek memory processors governing the satellites.

“Do we tell Joshua?” Ashly asked.

“Not yet,” Syrinx said. “I don’t want him alarmed. Let’s see if we can confirm the cause first.”

An hour after they began negotiating, Joshua and Quantook-LOU had finalized a list of twenty items to exchange. It was to be mainly information, formatted to the digital standard used by the Mosdva, with one physical sample of each item to prove the concept wasn’t merely a boastful lie.

“I’d like to move on to pure data now,” Joshua said. “We’re interested in as much of your history as you’re prepared to release; astronomical observations, particularly those dealing with the sun’s expansion; any significant cultural works; mathematics; the biochemical structure of your plant life. More if you’re willing.”

“Is this why you have come?” Quantook-LOU asked.

“I don’t understand.”

“You have ventured around the nebula, sixteen thousand light-years by your own telling. You believed the Tyrathca were all that lived here. You say you came purely to trade, which I do not believe. There can be no meaningful trade between us, the distance is too great. At most it would take two or three visits by ships such as yours to level all differences between us. Your technology is so superior we cannot even scan through your spacesuits to verify you are what you say you are; which means that any machinery you see here you will be able to understand and duplicate without our assistance. In effect, you are giving us a multitude of gifts. Yet you are not driven by altruism, you pretend you are here to trade. You persevere in the task of gaining information from us. Therefore, we ask, what is your true reason for coming to this star?”
