Redemption Ark

Clavain issued a neural command to the simple subpersona of the tender, and with a lurch they detached from the dark whale-like hull of Nightshade. The tender whisked him inwards, through the great rushing clockwork of the centrifugal wheels, towards the green heart of the null-gee core.

This stronghold, this particular Mother Nest, was only the latest to be built. Though there had always been a Mother Nest of sorts, in the war’s early stages it had only been the largest of many camouflaged encampments. Two-thirds of the Conjoined had been spread throughout the system in smaller bases. But separation brought its own problems. The individual groups had been light-hours apart, and the lines of communication between them had been vulnerable to interception. Strategies could not be evolved in real time, nor could the group-mind state be extended to encompass two or more nests. The Conjoiners had become fragmented and nervous. Reluctantly, the decision had been taken to absorb the smaller nests into one vast Mother Nest, hoping that the advantage gained through centralisation would outweigh the danger involved in placing all their eggs in one basket.

With hindsight, the decision had been massively successful.

The tender slowed as it neared the membrane of the null-gee core. Clavain felt utterly dwarfed by the green sphere. It glowed with its own soft radiance, like a verdant miniature planet. The tender squelched through the membrane, into air.

Clavain dropped a window, allowing the core’s atmosphere to mingle with the tender’s own. His nose prickled at the vegetative assault. The air was cool and fresh and moist, its smell that of a forest after an intense midmorning thunderstorm. Though he had visited the core on countless occasions, the scent nonetheless made Clavain think not of those previous visits but of his childhood. He could not say when or where, but he had certainly walked through a forest that had this quality. It had been somewhere on Earth — Scotland, perhaps.

There was no gravity in the core, but the vegetation that filled it was not a free-floating mass. Threading the sphere from side to side were spars of oak up to three kilometres long. The spars branched and merged randomly, forming a wooden cytoskeleton of pleasing complexity. Here and there the spars bulged sufficiently to accommodate enclosed spaces, hollows that glowed with pastel lantern-light. Elsewhere, a cobweb of smaller strands provided a structural mesh to which most of the greenery was anchored. The whole assemblage was festooned with irrigation pipes and nutrient feedlines, threading back into the support machinery lurking at the very heart of the core. Sun lamps studded the membrane at irregular intervals, and were distributed throughout the green masses themselves. Now they shone with the hard blue light of high noon, but as the day progressed — they were slaved to twenty-six-hour Yellowstone time — the lamps would slide down through the spectrum towards the bronze and russet reds of evening.

Eventually night would fall. The spherical forest would come alive with the chirrups and calls of a thousand weirdly evolved nocturnal animals. Squatting on a spar near its heart during nightfall, it would be easy to believe that the forest reached away in all directions for thousands of kilometres. The distant centrifugal wheels were only visible from the last hundred metres of greenery beneath the membrane, and they were, of course, utterly silent.

The tender dodged through the mass, knowing precisely where it had to take Clavain. Now and then he saw other Conjoiners, but they were mostly children or the elderly. The children were born and raised in the one-gee triplet, but when they were six months old they were brought here at regular intervals. Supervised by the elderly, they learned the muscle and orientation skills necessary for weightlessness. For most of them it was a game, but the very best would be earmarked for duty in the arena of space war. A few, a very few, showed such heightened spatial skills that they would be steered towards battle planning.

The elderly were too frail to spend much time in the high-gee rings. Once they had come to the core, they often never left. Clavain passed a couple now. They both wore support rigs, medical harnesses that doubled as propulsion packs. Their legs trailed behind them like afterthoughts. They were coaxing a quintet of children into kicking off from one side of a woody hollow into open space.
