Weather fell silent, her expression respectful. It was not necessary for her to tell us that the message was over.
“How do I know this is true?” Van Ness asked quietly.
“I can’t give you any guarantees,” Weather said, “but there was one word I was also meant to say to you. Your wife believed it would have some significance to you, something nobody else could possibly know.”
“And the word?”
“The word is ‘mezereon.’ I think it is a type of plant. Does the word mean something to you?”
I looked at Van Ness. He appeared frozen, unable to respond. His eye softened and sparkled. He nodded, and said simply, “Yes, it does.”
“Good,” Weather answered. “I’m glad that’s done: it’s been weighing on all of our minds for quite some time. And now I’m going to help you get home.”
Whatever “mezereon” meant to Van Ness, whatever it revealed to him concerning the truth of Weather’s message, I never asked.
Nor did Van Ness ever speak of the matter again.
She stood before the hexagonal arrangement of input dials, as I had done a thousand times before. “You must give me authorisation to make adjustments,” she said.
My mouth was dry. “Do what you will. I’ll be watching you very carefully.”
Weather looked amused. “You’re still concerned that I might want to kill us all?”
“I can’t ignore my duty to this ship.”
“Then this will be difficult for you. I must turn the dials to a setting you would consider highly dangerous, even suicidal. You’ll just have to trust me that I know what I’m doing.”
I glanced back at Van Ness.
“Do it,” he mouthed.
“Go ahead,” I told Weather. “Whatever you need to do—”
“In the course of this, you will learn more about our engines. There is something inside here that you will find disturbing. It is not the deepest secret, but it is a secret nonetheless, and shortly you will know it. Afterwards, when we reach port, you must not speak of this matter. Should you do so, Conjoiner security would detect the leak and act swiftly. The consequences would be brutal, for you and anyone you might have spoken to.”
“Then maybe you’re better off not letting us see whatever you’re so keen to keep hidden.”
“There’s something I’m going to have to do. If you want to understand, you need to see everything.”
She reached up and planted her hands on two of the dials. With surprising strength, she twisted them until their quadrants shone ruby red. Then she moved to another pair of dials and moved them until they were showing a warning amber. She adjusted one of the remaining dials to a lower setting, into the blue, and then returned to the first two dials she had touched, quickly dragging them back to green. While all this was happening, I felt the engine surge in response, the deck plates pushing harder against my feet. But the burst was soon over. When Weather had made her last adjustment, the engine had throttled back even further than before. I judged that we were only experiencing a tenth of a gee.
“What have you just done?” I asked.
“This,” she said.
Weather took a nimble, light-footed step back from the input controls. At the same moment a chunk of wall, including the entire hexagonal array, pushed itself out from the surrounding metallic-blue material in which it had appeared to have been seamlessly incorporated. The chunk was as thick as a bank-vault door. I watched in astonishment as the chunk slid in silence to one side, exposing a bulkhead-sized hole in the side of the engine wall.
Soft red light bathed us. We were looking into the hidden heart of a Conjoiner drive.
“Follow me,” Weather said.
“Are you serious?”
“You want to get home, don’t you? You want to escape that raider? This is how it will happen.” Then she looked back to Van Ness. “With all due respect . . . I wouldn’t recommend it, Captain. You wouldn’t do any damage to the engine, but the engine might damage you.”
“I’m fine right here,” Van Ness said.
I followed Weather into the engine. At first my eyes had difficulty making out our surroundings. The red light inside seemed to emanate from every surface, rather than from any concentrated source, so that there were only hints of edges and corners. I had to reach out and touch things more than once to establish their shape and proximity. Weather watched me guardedly, but said nothing.
She led me along a winding, restrictive path that squeezed its way between huge intrusions of Conjoiner machinery, like the course etched by some meandering, indecisive underground river. The machinery emitted a low humming sound, and sometimes when I touched it I felt a rapid but erratic vibration. I couldn’t make out our surroundings with any clarity for more than a few metres in any direction, but as Weather pushed on I sometimes had the impression that the machinery was moving out of her way to open up the path, and sealing itself behind us. She led me up steep ramps, assisted me as we negotiated near-impassable chicanes, helped me as we climbed down vertical shafts that would be perilous even under one-tenth of a gee. My sense of direction was soon hopelessly confounded, and I had no idea whether we had travelled hundreds of metres into the engine, or merely wormed our way in and around a relatively localised region close to our entry point.
“I’m glad you know the way,” I said, with mock cheer-fulness. “I wouldn’t be able to get out of here without you.”
“Yes, you will,” Weather said, looking back over her shoulder. “The engine will guide you out, don’t you worry.”
“You’re coming with me, though.”
“No, Inigo, I’m not. I have to stay here from now on. It’s the only way that any of us will be getting home.”
“I don’t understand. Once you’ve fixed the engine—”
“It isn’t like that. The engine can’t be fixed. What I can do is help it, relieve it of some of the computational burden. But to do that I need to be close to it. Inside it.”
While we were talking, Weather had brought us to a box-like space that was more open than anywhere we’d passed through so far. The room, or chamber, was empty of machinery, save for a waist-high cylinder rising from the floor. The cylinder had a flattened top and widened base that suggested the stump of a tree. It shone the same arterial red as everything else around us.
“We’ve reached the heart of the engine-control assembly now,” Weather said, kneeling by the stump. “The reaction core is somewhere else—we couldn’t survive anywhere near that—but this is where the reaction computations are made, for both the starboard and port drives. I’m going to show you something now. I think it will make it easier for you to understand what is to happen to me. I hope you’re ready.”
“As I’ll ever be.”
Weather planted a hand on either side of the stump and closed her eyes momentarily. I heard a click and the whirr of a buried mechanism. The upper fifth of the stump opened, irising wide. A blue light rammed from its innards. I felt a chill rising from whatever was inside, a coldness that seemed to reach fingers down my throat.
Something emerged from inside the stump, rising on a pedestal. It was a glass container pierced by many silver cables, each of which was plugged into the folded cortex of a single massively swollen brain. The brain had split open along fracture lines, like a cake that had ruptured in the baking. The blue light spilled from the fissures. When I looked into one—peering down into the geological strata of brain anatomy—I had to blink against the glare. A seething mass of tiny bright things lay nestled at the base of the cleft, twinkling with the light of the sun.
“This is the computer that handles the computations,” Weather said.
“It looks human. Please tell me it isn’t.”
“It is human. Or at least that’s how it started out, before the machines were allowed to infest and reorganise its deep structure.” Weather tapped a finger against the side of her own scalp. “All the machines in my head only amount to two hundred grams of artificial
matter, and even so I still need this crest to handle my thermal loading. There are nearly a thousand grams of machinery in that brain. The brain needs to be cooled like a turbopump. That’s why it’s been opened up, so that the heat can dissipate more easily.”
“It’s a monstrosity.”
“Not to us,” she said sharply. “We see a thing of wonder and beauty.”
“No,” I said firmly. “Let’s be clear about this. What you’re showing me here is a human brain, a living mind, turned into some kind of slave.”
“No slavery is involved,” Weather said. “The mind chose this vocation willingly.”
“It chose this?”
“It’s considered a great honour. Even in Conjoiner society, even given all that we have learned about the maximisation of our mental resources, only a few are ever born who have the skills necessary to tame and manage the reactions in the heart of a C-drive. No machine can ever perform that task as well as a conscious mind. We could build a conscious machine, of course, a true mechanical slave, but that would contravene one of our deepest strictures. No machine may think, unless it does so voluntarily. So we are left with volunteer organic minds, even if those selfsame minds need the help of a thousand grams of nonsentient processing machinery. As to why only a few of us have the talent . . . that is one of our greatest mysteries. Galiana thought that, in achieving a pathway to augmented human intelligence, she would render the brain utterly knowable. It was one of her few mistakes. Just as there are savants amongst the retarded, so we have our Conjoined equivalents. We are all tested for such gifts when we are young. Very few of us show even the slightest aptitude. Of those that do, even fewer ever develop the maturity and stability that would make them suitable candidates for enshrinement in an engine.” Weather faced me with a confiding look. “They are valued very highly indeed, to the point where they are envied by some of us who lack what they were born with.”
“But even if they were gifted enough that it was possible . . . no one would willingly choose this.”
“You don’t understand us, Inigo. We are creatures of the mind. This brain doesn’t consider itself to have been imprisoned here. It considers itself to have been placed in a magnificent and fitting setting, like a precious jewel.”
“Easy for you to say, since it isn’t you.”
“But it very nearly could have been. I came close, Inigo. I passed all the early tests. I was considered exceptional, by the standards of my cohort group. I knew what it was like to feel special, even amongst geniuses. But it turned out that I wasn’t quite special enough, so I was selected out of the programme.”
I looked at the swollen, fissured mind. The hard blue glow made me think of Cherenkov radiation, boiling out of some cracked fission core.
“And do you regret it now?”
“I’m older now,” Weather said. “I realise now that being unique . . . being adored . . . is not the greatest thing in the world. Part of me still admires this mind; part of me still appreciates its rare and delicate beauty. Another part of me . . . doesn’t feel like that.”
“You’ve been amongst people too long, Weather. You know what it’s like to walk and breathe.”
“Perhaps,” she said, doubtfully.
“This mind—”
“It’s male,” Weather said. “I can’t tell you his name, any more than I could tell you mine. But I can read his public memories well enough. He was fifteen when his enshrinement began. Barely a man at all. He’s been inside this engine for twenty-two years of shiptime; nearly sixty-eight years of worldtime.”
“And this is how he’ll spend the rest of his life?”
“Until he wearies of it, or some accident befalls this ship. Periodically, as now, Conjoiners may make contact with the enshrined mind. If they determine that the mind wishes to retire, they may effect a replacement, or decommission the entire engine.”
“And then what?”
“His choice. He could return to full embodiment, but that would mean losing hundreds of grams of neural support machinery. Some are prepared to make that adjustment; not all are willing. His other option would be to return to one of our nests and remain in essentially this form, but without the necessity of running a drive. He would not be alone in doing so.”
I realised, belatedly, where all this was heading. “You say he’s under a heavy burden now.”
“Yes. The degree of concentration is quite intense. He can barely spare any resources for what we might call normal thought. He’s in a state of permanent unconscious flow, like someone engaged in an enormously challenging game. But now the game has begun to get the better of him. It isn’t fun any more. And yet he knows the cost of failure.”
“But you can help him.”
“I won’t pretend that my abilities are more than a shadow of his. Still, I did make it part of the way. I can’t take all the strain off him, but I can give him free access to my mind. The additional processing resources—coupled with my own limited abilities—may make enough of a difference. ”
“For what?”
“For you to get wherever it is you are going. I believe that with our minds meshed together, and dedicated to this one task, we may be able to return the engines to something like normal efficiency. I can’t make any promises, though. The proof of the pudding . . .”
I looked at the pudding-like mass of neural tissue and asked the question I was dreading. “What happens to you, while all this is happening? If he’s barely conscious—”
“The same would apply, I’m afraid. As far as the external world is concerned, I’ll be in a state of coma. If I’m to make any difference, I’ll have to hand over all available neural resources.”
“But you’ll be helpless. How long would you last, sitting in a coma?”
“That isn’t an issue. I’ve already sent a command to this engine to form the necessary life-support machinery. It should be ready any moment now, as it happens.” Weather glanced down at the floor between us. “I’d take a step back if I were you, Inigo.”
I did as she suggested. The flat red floor buckled upwards, shaping itself into the seamless form of a moulded couch. Without any ceremony, Weather climbed onto the couch and lay down as if for sleep.
“There isn’t any point delaying things,” she said. “My mind is made up, and the sooner we’re on our way, the better. We can’t be sure that there aren’t other brigands within attack range.”
“Wait,” I said. “This is all happening too quickly. I thought we were coming down here to look at the situation, to talk about the possibilities.”
“We’ve already talked about them, Inigo. They boil down to this: either I help the boy, or we drift hopelessly.”
“But you can’t just . . . do this.”
Even as I spoke, the couch appeared to consolidate its hold on Weather. Red material flowed around her body, hardening over her into a semitranslucent shell. Only her face and lower arms remained visible, surrounded by a thick red collar that threatened to squeeze shut at any moment.
“It won’t be so bad,” she said. “As I said, I won’t have much room left for consciousness. I won’t be bored, that’s for sure. It’ll be more like one very long dream. Someone else’s dream, certainly, but I don’t doubt that there’ll be a certain rapturous quality to it. I remember how good it felt to find an elegant solution, when the parameters looked so unpromising. Like making the most beautiful music imaginable. I don’t think anyone can really know how that feels unless they’ve also held some of that fire in their minds. It’s ecstasy, Inigo, when it goes right.”
“And when it goes wrong?”
“When it goes wrong, you don’t get much time to explore how it feels.” Weather shut her eyes again, like a person lapsing into microsleep. “I’m lowering blockades, allowing the boy to co-opt my own resources. He’s wary. Not because he doesn’t trust me, but because he can barely manage his own processing tasks, without adding the temporary complexity of farming some of them out to me. The transition will be
difficult . . . ah, here it comes. He’s using me, Inigo. He’s accepting my help.” Despite being almost totally enclosed in the shell of red matter, Weather’s whole body convulsed. Her voice, when she spoke again, sounded strained. “It’s difficult. So much more difficult than I thought it would be. This poor mind . . . he’s had so much to do on his own. A lesser spirit would already have buckled. He’s shown heroic dedication . . . I wish the nest could know how well he has done.” She clamped her teeth together and convulsed again, harder this time. “He’s taking more of me. Eagerly now. Knows I’ve come to help. The sense of relief . . . the strain being lifted . . . I can’t comprehend how he lasted until now. I’m sorry, Inigo. Soon there isn’t going to be much of me left to talk to you.”
“Is it working?”
“Yes. I think so. Perhaps between the two of us—” Her jaws cracked together, teeth cutting her tongue. “Not going to be easy, but . . . losing more of me now. Language going. Don’t need now.”
“Weather, don’t go.”
“Can’t stay. Got to go. Only way. Inigo, make promise. Make promise fast.”
“Say it. Whatever it is.”
“When we get . . . when we—” Her face was contorted with the strain of trying to make herself understood.
“When we arrive,” I said.
She nodded so hard I thought her neck was going to break. “Yes. Arrive. You get help. Find others.”
“Other Conjoiners?”
“Yes. Bring them. Bring them in ship. Tell them. Tell them and make them help.”
“I will. I swear on it.”
“Going now. Inigo. One last thing.”
“Yes. Whatever it is.”
“Hold hand.”
I reached out and took her hand, in my good one.
“No,” Weather said. “Other. Other hand.”
I let go, then took her hand in my metal one, closing my fingers as tightly as I dared without risking hers. Then I leaned down, bringing my face close to hers.
