Four arms protruded from the body, branching out sixty centimeters above the hip joints. They were similar to the legs in respect of their size and all-around flexibility; differing only at the tip that split into a neat quad pincer arrangement that was quite capable of snipping through medium-sized branches. On the top of the main body four gill-like vents were spaced equidistantly around the crest, drawing air down into its lungs. Between them were the food inlets, mini trunks of rubbery flesh that had some independent movement. Motiles grazed on specific vegetation for the chemicals they contained, but mainly they sucked up water saturated with base cells. Both were processed in a large double stomach. The pap could be semidigested before being regurgitated to feed an immotile; after full digestion the residue was excreted from a single anus at the base of the body.
Above the gills and mouths, the body’s crown divided up into the four sensory stalks, which were the most pliable of all its limbs, capable of bending and twisting in every direction. At the very apex of them was the delicate nerve receptor, a thin impulse-permeable membrane stretched over raw ganglions; slightly below them were the eyes, then a pressure-sensitive blister that could detect sound waves, a plume of thin chemically responsive fibers that smelled the air, and a cluster of tactile cells capable of detecting temperature.
For such creatures, modifying the area around the pool to their own requirements was a relatively simple matter. They had long since mastered the rudiments of tool use, and quickly adapted sharp stones and sections of hard bark from the nearby trees. Using these as shovels and scoops, the twelve of them dug a shallow pond slightly upstream from the main pool, then lined it with stone taken from the excavated soil.
With the work complete, the four largest motiles waded into the pond, and once again linked their nerve receptors. This time the union went a lot deeper than simply connecting their thoughts. Their bodies were pressed up tight together, ready for amalgamation. The process was triggered by an internal hormone deluge brought on by the mental merger. Over the subsequent five weeks they underwent a tremendous metamorphosis. Their four separate bodies slowly coalesced on a cellular level to produce a single entity. Where their skin touched, it softened and melted away, creating a single giant body cavity. Inside that, their brains fused together and expanded; a transformation pattern followed by most of the major organs. The muscles simply wasted away, providing a source of nutrition to power the other changes. Legs shrank until they were nothing but a circular series of solid fleshy lumps that supported the new large body. Arms shriveled and dropped off, there was no need for them now. Digestive organs stretched out, and spread up around the new singular brain, like shoots of ivy twining around a tree trunk; underneath the brain, there was a new growth. The reproductive system that until now had been nascent began to grow into fully viable organs. Only the sensory stalks remained the same, feeding the developing brain a dodecagonal impression of the world around it.
At the end of the process, the new immotile Prime, MorningLightMountain, began to secure its territory. The remaining eight motiles came and went continually, feeding the immotile with their regurgitated pap. They had been instructed to gorge themselves on specific types of plants, enriching their food with certain vitamin types.
Triggered by the nourishment contained within its food, MorningLightMountain’s reproductive organs began to ovulate. The first batch of a hundred nucleiplasms was discharged from its body into the water, allowing them to drift down to the large pool. Base cells began to congregate around them.
By themselves, Prime base cells followed a life cycle similar to amoebas; they absorbed food through their membrane walls, and reproduced by fission, remaining a single-cell life-form that inhabited most of the planet’s waterways. But they also carried the DNA for a lot more than that. It was the nucleiplasms that initiated the multicellular stage, releasing activants for new sequences in the DNA, and switching off the amoeba-stage sequence. The cluster of cells around the nucleiplasm began to change, developing fresh organelles that provided specific functions. Like any multicellular organism, the cells began to specialize. The immotile had a degree of control over the type of nucleiplasm it gestated inside its reproduction system. By consciously controlling hormone secretion into the nucleiplasm, it could dictate the size of various organs, and by doing so design the structure and composition of a motile. If it needed heavy work doing, it would produce a batch of nucleiplasms that would congregate the largest and strongest motile. In a time when its territory was under threat, nucleiplasm to engender soldiers would be released.
The first herd of MorningLightMountain’s motiles began to wade out of the pond after three weeks of congregation. The existing motiles guided them over to the immotile, who touched its nerve receptors to theirs. Memory and instructions flashed through the impulse-permeable membrane, filling the motiles’ virgin brains with a compact version of its own thoughts.
Over the first decades, MorningLightMountain began to shape and fortify its valley. In those days there were few non-Prime life-forms left in the equatorial lands. Those that did still inhabit the valley such as the birds and a few rodentlike creatures were swiftly hunted down and exterminated—no immotile would tolerate competition for its own resources. The wild jungle was gradually cut back, the swamps drained into a network of canals that irrigated the big ferns that motiles ate. Stone was quarried, and used to construct a simple igloo-dome over the immotile as protection from the elements and any rogue predators from other territories. Metal ores were mined, and fires were used to forge crude weapon tips. The congregation pool was dredged and lined with stone.
After forty-five years of unrestricted growth, MorningLightMountain was reaching the limits of its management capacity. Over a thousand motiles were at work in the valley, and supervision was becoming difficult. A second immotile was amalgamated to compensate for the shortfall. MorningLightMountain’s pool and dome were extended, and four motiles brought together a couple of meters away from it. While the amalgamation was progressing, MorningLightMountain had six of its nerve receptors linked with those motiles undergoing the merger, pushing its thoughts into the new-growing brain. When it was all over, the two were permanently linked by four nerve receptors, producing an immotile duo with a much expanded mental capacity, and capable of organizing many herds of motiles.
A new phase of productivity began. The valley, when properly agrarianized, was capable of supporting thousands of motiles. To MorningLightMountain’s disappointment, however, it took almost all of its motiles just to keep the valley maintained. Thirty-five years later, a third immotile was amalgamated next to the initial duo. That was around the time it began to trade with immotiles of surrounding territories. Metal ores were exchanged for the use of soldier herds to repel a territory that was starting to encroach the top of the valley ramparts. Food ferns were swapped for hardwood trunks that made better spears and clubs. Ideas were bartered, chief among them the concept of plows and crop rotation brought in from immotiles thousands of kilometers away. It was the start of true agriculture for the Prime civilization, and the associated revolution that the innovation always introduced. The amount of produce that could be grown by a motile doubled within a decade. Seeing the possibility of the concept, the immotiles began to experiment, studying how the plants grew, what soils were best. MorningLightMountain itself was the one who worked out cross-pollination as a method of increasing yield and breeding new varieties. It was the start of the scientific method, and all that implied.
