Wormholes opened as close as possible to the stars of each new incursion system. Strong beams of light shone back through, brightening the asteroids and equipment that orbited the interstellar wormhole at the staging post. Ships were dispatched through to the dangerous environment, forming a protective perimeter. As predicted, the humans had not thought to station any defenses around their stars.
MorningLightMountain began firing its corona-rupture machine at the forty-eight new stars. The covering ships began their interference strategy.
Only at one star, Hanko, did the humans dispatch a starship to investigate. MorningLightMountain could do nothing more now but watch and wait. The corona-rupture machines were the most heavily automated apparatus it had ever built. It would never be able to place an immotile cluster in one of the small vessels, so it had to rely on electronics, which was a point of concern.
Several rival immotiles had developed their own versions of the corona-rupture technique during the centuries before the barrier imprisoned them. None could ever test it; to do so would be to kill all Prime life on the homeworld. It had remained a theory for over a thousand years, until the imprisonment ended.
When it wiped out the other immotile groups, MorningLightMountain was surprised that several of them had actually built and maintained corona-rupture machines. Investigation of their dwindling thoughts showed they were concerned about its own dominance, and believed the machines to be the last deterrent. With wormholes open to other star systems, MorningLightMountain had begun a comprehensive research project, firing the different kinds of corona-rupture machines at its disposal, and observing the results, using them to refine the design. It was gratifying to discover its own design was among the best.
Now it watched as the ruptures began, evolving into solar flares that jetted out vast clouds of particle radiation that would soon envelop the Commonwealth worlds. All the non-Prime life dwelling on the planets would sicken and die. It was the simplest, most effective solution to the problems it was facing. MorningLightMountain had suffered unexpected setbacks as it began to grow its crops on the new twenty-three worlds. Often it would see the seeds germinate, only for the young shoots to suffer some unknown malaise and wither away. The malady was different on every planet, and often varied from continent to continent.
Strangely, it was data that it mined from human sources that gave it the reason. Soil bacteria was different everywhere: non-Prime. Something it hadn’t realized, but it was obvious with hindsight. In addition, there were a myriad of spores and viruses, micro-organisms, and insects that would consume or clash with Prime-life plants. Humans countered this problem with genetically modified terrestrial crops that could grow on their newly acquired worlds. They twisted their food symbiosis plants into nonterrestrial versions; crops looked the same but their cellular biochemical functions were subtly different. Nothing humans did surprised MorningLightMountain anymore; but it was unable to understand how they could betray their biological heritage so casually. Did the integrity of their evolution mean nothing to them? Apparently not.
The human starship at Hanko had jumped away from the growing flare, but now it returned, emerging so close to the star that MorningLightMountain had trouble tracking it. A sensor on one of its covering ships detected a pulse of electromagnetic energy that might have been the starship firing something with a fusion drive. Then the ship jumped clear again. MorningLightMountain waited to see what would happen. It could not envisage a weapon capable of destroying a corona-rupture machine.
After the flare radiation had scoured each of the new forty-eight planets clean of its antagonistic alien life, MorningLightMountain would introduce Prime life onto all of them. It would be the true beginning of Primeforming the galaxy. With their food dead and rotting, the humans would be forced to abandon their worlds, leaving their valuable industrial equipment behind them. Should they choose to stay and fight for possession of their dead planets, the fleets were ready to overwhelm their defenses without any risk to itself. This was an economic method of incursion. MorningLightMountain had expended an inordinate amount of resources to rebuild and salvage from the wreckage of conflict on the new twenty-three, as well as countering all the guerrilla sabotage. Human equipment and technology were useful, but it was paying too high a price for acquiring it. And this second incursion included the Big15 world, Wessex, with its expansive industrial facilities. This time, MorningLightMountain would not be beaten back.
